Detailed Description

In the following description, reference is made to or shown in the accompanying drawings for the purpose of illustrating the general principles of the invention, and not for the purpose of limiting the same.

Referring to fig. 1 to 4, a fixing device 100 of the present application includes a base 1, two guiding members 2, a movable member 3, and two limiting mechanisms 4. The base 1 is used for bearing an object to be held. The base 1 may include a bottom plate 11, four frame bodies 12 and four fixing members 13. The number of the frames 12 and the fixing members 13 included in the base 1 can be varied according to the requirement, and basically, the number of the fixing members 13 is not less than the number of the frames 12.

The bottom plate 11 may include four engaging holes 111 and eight through holes 112. Each of the fitting holes 111 may penetrate the bottom plate 11 in a longitudinal direction, two through holes 112 may be formed around each of the fitting holes 111, each of the through holes 112 may be formed by recessing a side wall of the bottom plate 11 in a transverse direction, and each of the fitting holes 111 communicates with two adjacent through holes 112.

Each fitting hole 111 is used for fitting one fastener 13, and each fastener 13 includes two lock holes 131. Each of the locking holes 131 of each of the fixing elements 13 fitted into the fitting hole 111 of the base plate 11 communicates with one of the adjacent through holes 112. Each frame body 12 may have two fixing holes 121. The two screws S can be engaged with the two fixing holes 121 of each frame 12, the two locking holes 131 of each fixing member 13, and the two through holes 112 of the base plate 11, so as to fix the frame 12 and the base plate 11 to each other. The number of the fitting holes 111 and the number of the through holes 112 included in the bottom plate 11, and the number of the fixing holes 121 included in each frame body 12 are not limited to the above description.

In practical applications, each locking hole 131 is a hole with a screw thread, and each through hole 112 and each fixing hole 121 may be a through hole without a screw thread, but not limited thereto. Each frame 12 may be an L-shaped column structure, and four frames 12 may be correspondingly disposed at four corners of the bottom plate 11, and when the object to be held is disposed on the bottom plate 11, the four frames 12 are correspondingly held at four corners of the object to be held.

In a preferred embodiment, each fixing member 13 may be made of a material having a hardness higher than that of the base plate 11, so that the connection strength between the fixing member 13 and the base plate 11 can be greatly improved, and the problem of tooth slippage of the locking hole 131 of the fixing member 13 during the assembling process can be greatly avoided.

According to the above, by engaging the four fixing members 13 with the bottom plate 11 and engaging the plurality of screws S with the locking holes 131 of the fixing members 13, the frame body 12 is fixed to the bottom plate 11, and when the locking holes 131 slip, the related personnel only need to replace the fixing members 13, and do not need to replace the bottom plate 11.

The two guide members 2 are disposed on the base 1 at intervals, and each guide member 2 includes a plurality of engaging structures 21. The shape of each guiding member 2 may be a substantially cylindrical structure, and each engaging structure 21 included in each guiding member 2 may be, for example, a groove formed by recessing the guiding member 2 on a side away from the movable element 3, and the shape of each groove may be, for example, a cylinder, but not limited thereto, and the shape of each groove corresponds to the shape of the limiting element 41 and can be engaged with each other. The height of any one of the engaging structures 21 included in one of the guiding members 2 relative to the bottom plate 11 is the same as the height of one of the engaging structures 21 included in the other guiding member 2 relative to the bottom plate 11, and the number of the engaging structures 21 included in one of the guiding members 2 is the same as the number of the engaging structures 21 included in the other guiding member 2, that is, the two guiding members 2 may be completely the same members.

The movable element 3 is movably connected to the two guide members 2. Specifically, the movable member 3 may have two through holes 31, and the two guide members 2 are correspondingly disposed through the two through holes 31. In the drawings of the present embodiment, each through hole 31 is a closed through hole penetrating through the movable element 3, but each through hole 31 is not limited to a closed through hole, and in different embodiments, the through hole 31 may be in the form of a notch communicating with the outside.

Each limiting mechanism 4 is connected with one end of the moving part 3, and the two limiting mechanisms 4 can be matched with the two guide members 2, so that the moving part 3 cannot move relative to the bottom plate 11, and the moving part 3 and the bottom plate 11 can jointly fix the object to be fixed. Moreover, the two position-limiting mechanisms 4 can be operated, so that the moving member 3 can move relative to the two guiding members 2, so that the moving member 3 no longer holds the object to be held together with the bottom plate 11, and when the two position-limiting mechanisms 4 are operated, related personnel or equipment can further cause the moving member 3 to move along the two guiding members 2 in a direction away from the bottom plate 11, and accordingly leave the two guiding members 2. In the drawings of the present embodiment, the movable element 3 is a plate-shaped structure, but the shape of the movable element 3 is not limited to this, and the shape of the movable element 3 may vary according to the shape of the object to be held.

As shown in fig. 5 to 8, each of the stopper mechanisms 4 is connected to one of the guide members 2 and one end of the movable member 3. Each of the stopper mechanisms 4 may include: two limiting members 41, two elastic restoring members 42 and an operating member 43. The number of the stoppers 41 included in each stopper mechanism 4 is not limited to two. The number of the elastic restoring elements 42 included in each of the limiting mechanisms 4 is not limited to two.

Each limiting member 41 can be engaged with one of the engaging structures 21 of the adjacent guiding members 2, in this embodiment, the shape of each engaging structure 21 is a cylindrical groove, and the shape of each limiting member 41 is a substantially cylindrical structure, but the shapes of each engaging structure 21 and each limiting member 41 are not limited thereto. Each elastic restoring component 42 is connected to each limiting component 41. Each operating element 43 is operable to transition between a restrained state (as shown in fig. 5 and 6) and a released state (as shown in fig. 7 and 8).

When the operating element 43 is operated to switch from the limiting state (as shown in fig. 5 and 6) to the releasing state (as shown in fig. 7 and 8), the operating element 43 drives the limiting element 41, so that the limiting element 41 is no longer engaged with the adjacent engaging structure 21, and the elastic restoring element 42 is pressed to generate an elastic restoring force. When both the operating elements 43 are operated to change from the restricting state (as shown in fig. 5 and 6) to the releasing state (as shown in fig. 7 and 8), the movable member 3 can move relative to the two guide members 2.

When the operating element 43 is no longer operated and is converted from the released state (as shown in fig. 7 and 8) to the restricted state (as shown in fig. 5 and 6), the elastic restoring force generated by the pressing of the elastic restoring element 42 drives the limiting element 41, so that the limiting element 41 is again engaged with the adjacent engaging structure 21. When both the operating elements 43 are no longer operated and are switched from the released state (as shown in fig. 7 and 8) to the restricted state (as shown in fig. 5 and 6), the movable member 3 cannot move relative to the two guide members 2.

As described above, in short, when the two operation components 43 are not operated, the two operation components 43 may be in the limited state (as shown in fig. 5 and 6), and the limiting member 41 included in each limiting mechanism 4 is correspondingly engaged with one of the engaging structures 21 of the adjacent guiding members 2, at this time, the movable member 3 is limited and cannot move relative to the two guiding members 2, and the movable member 3 and the base 1 can jointly hold the object to be held.

In contrast, when the two operating components 43 are operated simultaneously and the two operating components 43 are both converted from the limiting state (as shown in fig. 5 and 6) to the releasing state (as shown in fig. 7 and 8), each limiting member 41 of each limiting mechanism 4 will not be engaged with one of the adjacent engaging structures 21, and at this time, the movable member 3 can move along the two guiding members 2 in a direction away from the bottom plate 11 or close to the bottom plate 11.

More specifically, referring to fig. 6 and 8 to 12, each of the limiting mechanisms 4 may further include a main body 44, an auxiliary member 45, and an auxiliary elastic restoring member 46. The body 44 has an accommodating groove 44A and four locking holes 44B, and one end of the movable member 3 is disposed in the accommodating groove 44A. The screws S can be engaged with the four locking holes 44B of the body 44 and the locking holes 32 at one end of the movable member 3, so that the position-limiting mechanism 4 is fixed to one end of the movable member 3.

The body 44 includes two through holes 44C, each through hole 44C penetrates the body 44, the two elastic restoring elements 42 are disposed in the two through holes 44C, and one end of each elastic restoring element 42 is fixed to the body 44. Each through hole 44C is formed with an opening 44C1 on a side of the body 44 adjacent to the receiving groove 44A. Each resilient return member 42 may be a tension spring. Each of the position-limiting members 41 is inserted into an expansion spring (elastic restoring element 42) located in the through hole 44C, and one end of each of the position-limiting members 41 is exposed to one of the openings 44C1 at one end of the body 44 adjacent to the movable element 3. The other end of each elastic restoring component 42 is fixed to the limiting component 41.

As described above, each body 44 can be fixed to one end of the movable member 3 by four screws S, and one end of each stopper 41 protruding out of each opening 44C1 of the body 44 can be correspondingly engaged with one of the engaging structures 21 of the adjacent guide members 2. That is, the two limiting mechanisms 4 are fixedly disposed at two ends of the movable member 3, and one end of each of the two limiting members 41 of each limiting mechanism 4 can be correspondingly engaged with the two engaging structures 21 of the adjacent guiding members 2.

As shown in fig. 6 and 8, when the operating element 43 is switched from the limiting state (as shown in fig. 5 and 6) to the releasing state (as shown in fig. 7 and 8), one end of each limiting element 41 moves away from the movable element 3, and is no longer engaged with the adjacent engaging structure 21, and the extension spring (elastic restoring element 42) connected to the limiting element 41 moves together with the limiting element 41 and is pressed to generate an elastic restoring force.

As shown in fig. 6 and 8, when the operating assembly 43 is no longer operated and is converted from the released state (as shown in fig. 7 and 8) to the restricted state (as shown in fig. 5 and 6), the elastic restoring force generated by the compression of the expansion spring will restore the position of the limiting members 41 to the state of not being driven, and one end of each limiting member 41 will be engaged with one of the adjacent engaging structures 21 again.

As shown in fig. 6 and 8 to 12, the auxiliary member 45 may be fixed to an end of the body 44 away from the movable member 3 by 4 screws S, and the auxiliary member 45 may include a through hole 451, where the through hole 451 is disposed through the auxiliary member 45. The number of screws S used for fixing one side of the main body 44 by the auxiliary member 45 is not limited to 4.

The operating member 43 may include an operating member 431, four links 432, and two pivots 433. The number of links 432 and the number of pivots 433 included in the operating member 43 are not limited to those shown in the drawings. In various embodiments, the operating member 43 may only include two links 432 and one pivot 433.

The operation member 431 may include a pushing portion 4311 and an operation portion 4312, the pushing portion 4311 is disposed through the through hole 451 of the auxiliary member 45, and one end of the pushing portion 4311 protrudes out of the auxiliary member 45. The other end of the pushing part 4311 can be fixed to the operating part 4312 by 2 screws S. The operation portion 4312 is used for pressing by a user. When the user presses the operating portion 4312, the pushing portion 4311 moves relative to the auxiliary member 45.

Each link 432 includes a through hole 4321 and a pivot hole 4322. Both ends of each pivot 433 are inserted into two shaft holes 44D of the body 44. The position of the body 44 adjacent to each shaft hole 44D may be provided with a screw S for limiting the movable range of the pivot 433 located in the shaft hole 44D relative to the body 44, and the movable range of each pivot 433 relative to the body 44 can be limited by two screws S. Each pivot 433 is disposed through the two pivot holes 4322 of the two links 432, and the two links 432 can rotate relative to the pivot 433 under the action of external force.

Each limiting member 41 may include a longitudinal structure 411 and a transverse structure 412, one end of the longitudinal structure 411 is connected to the middle position of the transverse structure 412, and the shape of each limiting member 41 is substantially T-shaped. The end of the longitudinal structure 411 opposite to the end connected to the transverse structure 412 is used for engaging with the engaging structure 21, and the two ends of the transverse structure 412 are respectively inserted into the two through holes 4321 of the two connecting rods 432.

In practical applications, the longitudinal structure 411 may include a locking hole 4111, the resilient restoring element 42 is sleeved on the longitudinal structure 411, the locking hole 4111 is used to provide a stud S1 for locking, and one end of the resilient restoring element 42 abuts against the stud S1 locked in the locking hole 4111. The longitudinal structure 411 of the elastic restoring element 42 is sleeved on, and is to be inserted into the through hole 44C of the body 44, and one end of the elastic restoring element 42 sleeved on the longitudinal structure 411 may be fixed on one side of the body 44 by two screws S, for example.

In a preferred application, each of the operating elements 43 may further include two limiting sleeves 434, and each of the limiting sleeves 434 is sleeved on one of the pivots 433. The two connecting rods 432 and the limiting sleeve 434 are sleeved together on the same pivot 433, and the limiting sleeve 434 is correspondingly located between the two connecting rods 432. Each of the limiting sleeves 434 is used to prevent the two links 432 from moving toward each other when they rotate relative to the pivot 433.

One end of the auxiliary elastic restoring element 46 is inserted into a through hole 44E of the main body 44 and fixed to the main body 44, and the other end of the auxiliary elastic restoring element 46 is fixed to the pushing portion 4311 of the operating assembly 43. In practical applications, the operating element 43 may further include an auxiliary element 435, the auxiliary element 435 is fixed to the pushing portion 4311, and the auxiliary elastic restoring element 46 is correspondingly sleeved on the auxiliary element 435. By providing the auxiliary member 435, the auxiliary resilient restoring member 46 can be restricted from being deformed substantially in an axial direction.

As shown in fig. 6 and 10 to 12, when the operating element 43 is in the restricting state, the two elastic restoring elements 42 and the auxiliary elastic restoring element 46 are in the non-pressed state (or may be in a slightly pressed state), while each link 432 is in the non-rotated state, and one end of the pushing portion 4311 is disposed adjacent to one end of each link 432.

As shown in fig. 6 and 8 to 12, when the operating portion 4312 is pressed, the operating portion 4312 moves toward the auxiliary member 45, and the operating portion 4312 drives the pushing portion 4311 to move, so that one end of the pushing portion 4311 pushes against the auxiliary elastic restoring member 46 and one end of each of the adjacent links 432. The links 432 pushed by the pushing portions 4311 rotate relative to the pivot 433. The rotated link 432 drives the transverse structure 412 of the position-limiting member 41 to move away from the body 44, the longitudinal structure 411 of the position-limiting member 41 moves along with the transverse structure 412, and one end of the longitudinal structure 411 moves towards the inside of the through hole 44C, and one end of the longitudinal structure 411 can no longer protrude out of the opening 44C1, so that the longitudinal structure 411 is no longer engaged with the adjacent engaging structure 21. During the movement of the longitudinal structure 411 relative to the body 44, the stud S1 fixed on the longitudinal structure 411 pushes against one end of the elastic restoring element 42, and the elastic restoring element 42 is compressed.

As described above, simply speaking, when the operation element 431 of the operation element 43 is pressed and the operation element 43 is converted from the restricted state (as shown in fig. 5 and 6) to the released state (as shown in fig. 7 and 8), the pushing portion 4311 pushes the adjacent link 432 and the auxiliary resilient restoring member 46, and the auxiliary resilient restoring member 46 is pressed and generates the resilient restoring force.

When the operation member 431 of the operation assembly 43 is no longer pressed, the elastic restoring force generated by the pressing of the auxiliary elastic restoring member 46 pushes the pushing portion 4311, so that the pushing portion 4311 moves away from the connecting rods 432, and accordingly, the operation member 431 is no longer pushed against each connecting rod 432, and the operation portion 4312 returns to the non-pressed position; when each link 432 is no longer pushed by the pushing portion 4311, the elastic restoring force generated by the pressing of each elastic restoring component 42 will move each limiting member 41 toward the guiding member 2, so as to drive each link 432 to rotate relative to the body 44, and return each link 432 to the position where it is not pushed by the pushing portion 4311.

As shown in fig. 5 to 8, in summary, when the operation portion 4312 is not pressed, one end of the longitudinal structure 411 of each limiting member 41 is engaged with the adjacent engaging structure 21, and each elastic restoring element 42 and the auxiliary elastic restoring element 46 are in an unstressed state; when a user presses the two operation portions 4312, each pushing portion 4311 moves relative to the auxiliary member 45 and pushes the four connecting rods 432, so that each connecting rod 432 rotates in the direction of the operation member 431, and each limiting member 41 is driven to move in the direction away from the engaging structure 21, so that each limiting member 41 is no longer engaged with the adjacent engaging structure 21, and at this time, the user can move the movable member 3 in the direction away from or close to the bottom plate 11 along the two guide members 2 under the condition that the user continuously presses the two operation portions 4312; after the user moves the movable element 3 to the desired position, the user only needs to press the two operation portions 4312 no longer, and the elastic restoring force generated by the pressing of each auxiliary elastic restoring member 46 and each elastic restoring component 42 drives each pushing portion 4311, each limiting member 41, and each connecting rod 432 to return to the position of the operation element 431 when not pressed, and one end of each limiting member 41 is engaged with the adjacent engaging structure 21 again.

Uploading the two limiting mechanisms 4 of the present embodiment, when the user wants to move the movable element 3 relative to the two guiding members 2, the user must continuously press the two operation portions 4312, which may cause some inconvenience in operation. Therefore, in a preferred embodiment, the holding device 100 may further include an unlocking element 47 and an auxiliary limiting element 48.

As shown in fig. 12 to 14, each unlocking assembly 47 is connected to one of the limiting mechanisms 4, each auxiliary limiting assembly 48 is disposed on the pushing portion 4311 of one of the limiting mechanisms 4, each auxiliary limiting assembly 48 can move along with the pushing portion 4311 connected thereto, and each auxiliary limiting assembly 48 can be engaged with one limiting structure 49 of the limiting mechanism 4. The limiting structure 49 and the auxiliary limiting component 48 engaged with each other can limit the moving range of the pushing portion 4311 relative to the main body 44 together, so that the limiting member 41 is kept from being engaged with the adjacent engaging structure 21.

As shown in fig. 13 and 14, when the operating element 431 is pressed and the pushing portion 4311 pushes the connecting rod 432, the auxiliary position-limiting component 48 moves along with the pushing portion 4311 and is engaged with the position-limiting structure 49; when the auxiliary limit assembly 48 and the limit structure 49 are engaged with each other, the pushing portion 4311 cannot move relative to the main body 44, and the operating portion 4312 of the operating element 431 cannot return to the non-pressed position even if the operating portion 4312 is no longer pressed.

That is, when the user presses the two operation portions 4312 to engage each auxiliary limiting element 48 with the adjacent limiting structure 49, since each pushing portion 4311 is limited and cannot move relative to the body 44, the user can directly move the movable member 3 relative to the two guide members 2 without continuously pressing the operation portions 4312, and thus, the operation convenience of the user can be greatly improved.

As shown in fig. 6, 8, 13 and 14, when the limiting structure 49 and the auxiliary limiting component 48 are engaged with each other, a user can operate the unlocking component 47 to make the auxiliary limiting component 48 no longer engaged with the limiting structure 49, so that the pushing portion 4311 will move in a direction away from the main body 44 under the action of the elastic restoring force generated by the auxiliary elastic restoring component 46 under pressure, and each of the limiting members 41 will move in a direction close to the guiding member 2 under the action of the elastic restoring force generated by the elastic restoring component 42 under pressure, whereby one end of each of the limiting members 41 will be engaged with the adjacent engaging structure 21.

That is, when the user presses the operation portion 4312 to engage each auxiliary limiting element 48 with the adjacent limiting structure 49, and moves the moving element 3 to a desired position, the user can operate the unlocking element 47 to disengage each auxiliary limiting element 48 from the adjacent limiting structure 49, so that the four limiting members 41 included in the two limiting mechanisms 4 are engaged with the adjacent engaging structures 21 again.

In summary, after the user presses the two operation portions 4312, the movable member 3 can be moved to the desired position without continuously pressing the operation portions 4312; after the user moves the movable element 3 to a desired position, the plurality of limiting members 41 included in the two limiting mechanisms 4 can be engaged with the adjacent engaging structures 21 again only by operating the two unlocking assemblies 47, so that the movable element 3 is fixed again.

Referring to fig. 9, 12 to 14, fig. 13 is a partial sectional view of the operation assembly 43 in the limiting state and the limiting mechanism 4, and fig. 14 is a partial sectional view of the operation assembly 43 in the releasing state and the limiting mechanism 4. Each auxiliary limiting assembly 48 may include an auxiliary limiting elastic member 481 and an auxiliary abutting member 482. The pushing portion 4311 may have a through hole 4311A, the auxiliary limiting elastic element 481 is disposed in the through hole 4311A of the pushing portion 4311, one end of the auxiliary limiting elastic element 481 is fixed to the pushing portion 4311, the other end of the auxiliary limiting elastic element 481 is fixed to the auxiliary abutting element 482, and a portion of the auxiliary abutting element 482 is exposed from the through hole 4311A of the pushing portion 4311. When the auxiliary abutting member 482 is pressed to move toward the inside of the through hole 4311A of the abutting portion 4311, the auxiliary limiting elastic member 481 is pressed to generate an elastic restoring force; when the auxiliary propping element 482 is no longer pressed, the auxiliary spacing elastic element 481 generates an elastic restoring force to restore the auxiliary propping element 482 to an unstressed position.

Each limit structure 49 may be a through hole penetrating the auxiliary member 45, and each limit structure 49 is disposed to face the adjacent pushing part 4311. In various embodiments, the limiting structure 49 can also be a through hole formed in the body 44.

Each unlocking assembly 47 may include an unlocking abutting member 471, an unlocking elastic member 472, and a fixing member 473, wherein a portion of the unlocking abutting member 471 is disposed through the through hole (the limiting structure 49) of the auxiliary member 45, and one end of the unlocking abutting member 471 penetrates through one end of the through hole (the limiting structure 49) of the auxiliary member 45, and a user can press the unlocking abutting member 471 exposed out of the through hole of the auxiliary member 45. The unlocking elastic member 472 is disposed in the through hole (the limiting structure 49) of the auxiliary member 45, one end of the unlocking elastic member 472 is fixed to the auxiliary member 45, and the other end of the unlocking elastic member 472 is connected to the unlocking abutting member 471.

When the user presses the unlocking abutting part 471 exposed out of the through hole of the auxiliary member 45, the unlocking elastic part 472 is pressed to generate an elastic restoring force; when the user no longer presses the unlocking abutting member 471, the unlocking abutting member 471 will be restored to the non-pressed position under the action of the elastic restoring force. The fixing piece 473 may be fixed to one side of the auxiliary member 45 by two screws S, for example, and the fixing piece 473 serves to limit the movable range of the unlocking elastic piece 472 with respect to the auxiliary member 45.

As shown in fig. 13, when the operation portion 4312 is not pressed, one end of the auxiliary abutting piece 482 abuts against the inner wall of the auxiliary member 45, and is retracted into the through hole 4311A of the abutting portion 4311, so that the auxiliary limiting elastic piece 481 is in a pressed state. As shown in fig. 14, when the operating portion 4312 is pressed and the pushing portion 4311 moves relative to the auxiliary member 45, one end of the auxiliary pushing member 482 correspondingly moves into the through hole (the limiting structure 49) of the auxiliary member 45, and at this time, the pushing portion 4311 cannot move relative to the auxiliary member 45 because a part of the auxiliary pushing member 482 is located in the through hole (the limiting structure 49) of the auxiliary member 45.

As shown in fig. 6, 8 and 14, when one end of the unlocking abutting piece 471 is pressed by a user, the unlocking abutting piece 471 will move relative to the auxiliary member 45, and the unlocking abutting piece 471 is adjacent to one end of the auxiliary abutting piece 482, so that the auxiliary abutting piece 482 will be pushed out of the through hole (the limiting structure 49) of the auxiliary member 45, and the auxiliary abutting piece 482 is no longer engaged with the through hole (the limiting structure 49) of the auxiliary member 45. When the auxiliary propping element 482 is no longer in contact with the through hole (the limit structure 49) of the auxiliary member 45 and the operating portion 4312 of the operating element 431 is not pressed, the elastic restoring force generated by the pressing of the auxiliary elastic restoring element 46 will move the propping portion 4311 to the position where the operating portion 4312 is not pressed, and the propping portion 4311 will not prop against the connecting rod 432, and the elastic restoring elements 42 will move one end of the limit elements 41 toward the adjacent engaging structure 21 and engage with the adjacent engaging structure.

As described above, when the user presses the unlocking abutting member 471 without pressing the operating portion 4312 of the operating member 431, the user will see that the operating portion 4312 automatically moves in a direction away from the auxiliary member 45; that is, when the user presses the unlocking abutting member 471, the user can determine whether the limiting mechanism 4 has limited the moving range of the moving member 3 relative to the guiding member 2 by looking at whether the operating portion 4312 has moved in the direction away from the auxiliary member 45, and accordingly determine whether the user can release his/her hand and can not hold the moving member 3.

Please refer to fig. 15 to 17, which are schematic views illustrating a second embodiment of the holding device of the present application. The holding device 200 of the present embodiment includes: a base 1, two guiding components 5, a movable component 3 and two limiting mechanisms 6. The base 1 and the movable element 3 of the present embodiment are the same as the base 1 and the movable element 3 described in the previous embodiments, and a description thereof will not be given below.

The base 1, the two guiding members 5, the moving member 3 and the two limiting mechanisms 6 in the embodiment are substantially the same in operation relationship as the previous embodiment, that is, when the user does not operate the two limiting mechanisms 6, the moving member 3 is limited by the two limiting mechanisms 6 and cannot move relative to the two guiding members 5; when the user operates the two limiting mechanisms 6, the movable member 3 can be operated to move along the two guide members 5. The present embodiment is different from the previous embodiments in that: the members included in each stopper mechanism 6 and their interlocking relationship are not exactly the same as those included in the stopper mechanism 4 of the foregoing embodiment, and will be described in detail below.

Each guide member 5 of the present embodiment is different from each guide member 2 of the previous embodiment in that: the plurality of engaging structures 51 of each guide member 5 are provided to face the plurality of engaging structures 51 of the other guide member 5, and each engaging structure 51 is a triangular pillar-shaped structure.

Referring to fig. 17 to 21, each of the limiting mechanisms 6 includes a body 61, two limiting members 62, two elastic restoring members 63, and an operating member 64. The two limiting members 62 are pivotally connected to the body 61, one end of each of the two elastic restoring members 63 is fixed to the body 61, the other end of each of the elastic restoring members 63 abuts against one of the limiting members 62, and the operating member 64 is connected to the body 61. The operating element 64 is operable to transition between a restrained state (as shown in fig. 22) and an unlocked state (as shown in fig. 23).

When the operating element 64 is operated to switch from the limiting state (as shown in fig. 22) to the releasing state (as shown in fig. 23), the operating element 64 drives the limiting element 62, so that the limiting element 62 is no longer engaged with the adjacent engaging structure 21, and the elastic restoring element 63 is pressed to generate an elastic restoring force; when the operating element 64 is no longer operated and the operating element 64 is converted from the released state (as shown in fig. 23) to the restricted state (as shown in fig. 22), the elastic restoring force generated by the pressing of the elastic restoring element 63 drives the limiting element 62, so that the limiting element 62 is again engaged with the adjacent engaging structure 21.

Further, as shown in fig. 19 to 23, one end of the body 61 has an accommodation groove 611, the accommodation groove 611 is used for accommodating a portion of the movable element 3, and the body 61 may be fixed to the movable element 3 by a plurality of screws. The body 61 further includes a receiving hole 612, the receiving hole 612 penetrates the body, and the receiving hole 612 is configured to be sleeved on one of the guiding members 5. It should be noted that the two guiding members 5 included in the holding device 200 of the present embodiment are correspondingly inserted into the two receiving through holes 612 of the two limiting mechanisms 6, and the two guiding members 5 are not inserted into the movable member 3.

In a preferred embodiment, each of the position-limiting mechanisms 6 may further include a cover plate 6A, the cover plate 6A may be fixed to one side of the body 61 by four screws S, and the cover plate 6A is used to shield a portion of the receiving groove 611, so as to prevent external contaminants from directly entering the receiving groove 611.

Each of the limiting mechanisms 6 further includes two pivot shafts 65, the body 61 further includes four shaft holes 613, two ends of each pivot shaft 65 penetrate through two of the shaft holes 613, a screw S may be disposed around the body 61 adjacent to each shaft hole 613, and the screw S can be used to limit the moving range of the pivot shaft 65 relative to the body 61.

Each of the position-limiting members 62 may have a through hole 62A, and each of the pivot shafts 65 is disposed through one of the position-limiting members 62, and the position-limiting members 62 can rotate relative to the pivot shafts 65. The two position-limiting members 62 pivotally connected to the body 61 through the two pivot shafts 65 are correspondingly located in the receiving through holes 612, and each position-limiting member 62 can swing relative to the body 61 under the action of an external force. The end of each limiting member 62 away from the end pivoted to the pivot 65 can be engaged with one of the adjacent engaging structures 21. When one end of the limiting member 62 is engaged with one of the engaging structures 21, if the limiting member 62 swings relative to the main body 61 under the action of an external force, one end of the limiting member 62 can no longer be engaged with the engaging structure 21.

Each elastic restoring element 63 may include an elastic element 631 and a propping element 632, the elastic element 631 is disposed in a through hole 614 of the body 61, one end of the elastic element 631 is fixed to the body 61, the other end of the elastic element 631 is fixed to the propping element 632, one end of the propping element 632 protrudes from the body 61 and is exposed out of the accommodating through hole 612, and one end of the propping element 632 exposed out of the accommodating through hole 612 correspondingly props against the adjacent limiting element 62.

When the position-limiting member 62 swings relative to the body 61 under the action of an external force, the position-limiting member 62 will push against the elastic member 631 of the elastic restoring member 63, and after the elastic member 631 is pushed, the elastic member 631 of the elastic restoring member 63 will be pressed to generate an elastic restoring force, so that when the position-limiting member 62 is no longer under the action of the external force, the elastic restoring force generated by the elastic member 631 will make the position-limiting member 62 return to the position where the position-limiting member 62 swings without the action of the external force.

The body 61 has a recess 615 formed at an end opposite to the end having the receiving groove 611. The operation assembly 64 includes an operation element 641 and four linking elements 642. The operating element 641 is connected to four linking elements 642, and the operating element 641 is disposed in the groove 615 of the body 61. One end of each linking member 642 is fixed to the operating member 641, and a portion of each linking member 642 passes through one of the through holes 616 of the body 61 and is exposed to the receiving through hole 612. Two of the linking members 642 are exposed out of one end of the accommodating through hole 612 and correspondingly abut against one of the position-limiting members 62, and the other two linking members 642 are exposed out of one end of the accommodating through hole 612 and correspondingly abut against the other position-limiting member 62.

As shown in fig. 22 and 23, the operating element 641 can be operated to move relative to the body 61, and accordingly, the four linking elements 642 are driven to move toward the two position-limiting elements 62. When the four linking elements 642 are driven by the operating element 641 to move in a direction close to the movable element 3 relative to the main body 61, the four linking elements 642 can correspondingly push the two position-limiting elements 62, so that the two position-limiting elements 62 swing relative to the main body 61; the end of the position-limiting element 62 that is pushed and swung by the linking element 642 is no longer engaged with the adjacent engaging structure 21, so that the position-limiting mechanism 6 is switched from the corresponding limiting state to the releasing state.

In a preferred embodiment, each of the position-limiting mechanisms 6 further includes an auxiliary elastic restoring member 66, one end of the auxiliary elastic restoring member 66 is fixed to the body 61, the other end of the auxiliary elastic restoring member 66 is connected to the operating member 641, and the auxiliary elastic restoring member 66 is correspondingly located between the operating member 641 and the body 61. In particular, the secondary elastic return 66 may be a telescopic spring. When the operation element 641 is pressed by a user and moves toward the main body 61, the auxiliary elastic restoring element 66 is pressed to generate an elastic restoring force, so that when the user no longer presses the operation element 641, the elastic restoring force generated by the auxiliary elastic restoring element 66 restores the operation element 641 to an unpressed position, thereby driving the four linkage elements 642 to move away from the movable element 3.

When the four linkage elements 642 move along with the operating element 641 in a direction away from the moving element 3, each of the position-limiting elements 62 is no longer abutted by the linkage elements 642, and each of the position-limiting elements 62 swings relative to the body 61 under the action of the elastic restoring force generated by the elastic element 631 of the elastic restoring element 63, so that one end of each of the position-limiting elements 62 swings in the direction of the guiding member 5, and finally, one end of each of the position-limiting elements 62 is engaged with one of the engaging structures 21.

In other words, as shown in fig. 22, when the operating element 641 is not pressed, one end of the abutting element 632 of each elastic restoring element 63 abuts against one side of the limiting element 62, so that one end of the limiting element 62 is stably engaged with one of the adjacent engaging structures 21. As shown in fig. 23, when the operating element 641 is pressed, the operating element 641 drives the four linking elements 642 to move toward the moving element 3, and one end of each linking element 642 abuts against the other side of the two limiting elements 62, so that each limiting element 62 swings relative to the body 61, and one end of each limiting element 62 close to the engaging structure 21 swings toward a direction away from the engaging structure 21, and is no longer engaged with one of the engaging structures 21, and at this time, a user can operate the moving element 3, so that the moving element 3 moves relative to the guiding member 5.

In one preferred embodiment, each of the position-limiting members 62 may include a first abutting surface 621 and a second abutting surface 622, and the first abutting surface 621 and the second abutting surface 622 are disposed adjacent to each other. When the operating element 64 is operated to be in the limiting state, the first abutting surface 621 of each limiting member 62 can abut against one side surface of one of the adjacent engaging structures 21 to limit the movable range between the movable member 3 and the guiding member 5, and the second abutting surface 622 of each limiting member 62 can abut against one side surface of the other adjacent engaging structure 21 to limit the movable range between the movable member 3 and the guiding member 5.

More specifically, when the operating element 641 is not pressed, if the movable element 3 is subject to an external force and intends to move in a direction away from the bottom plate 11, the first abutting surface 621 of each of the limiting members 62 abuts against the side surface 511A of one of the adjacent triangular columnar structures (the engaging structure 51), and the movable element 3 cannot move relative to the guiding member 5. Similarly, in a case where the operating element 641 is not pressed, if the movable element 3 is subject to an external force and intends to move in a direction approaching the bottom plate 11, the second abutting surface 622 of each of the position-limiting members 62 abuts against the side surface 511B of one of the adjacent triangular columnar structures (the engaging structure 51), and the movable element 3 cannot move relative to the guiding member 5. Therefore, by making each engaging structure 51 a triangular prism structure and making each limiting member 62 have the first abutting surface 621 and the second abutting surface 622, the movable member 3 is relatively hard to be affected by external force and moves relative to the two guiding members 5 when the operating element 64 is in the limiting state.

In one preferred embodiment, the holding device 200 may further include an unlocking element 67 and an auxiliary limiting element 68. The unlocking assembly 67 is connected with the limiting mechanism 6, the auxiliary limiting assembly 68 is disposed on the operating element 641, the auxiliary limiting assembly 68 can move along with the operating element 641, and the auxiliary limiting assembly 68 can be mutually clamped with a limiting structure 69 of the limiting mechanism 6. The limiting structure 69 and the auxiliary limiting component 68 can be engaged with each other to limit the moving range of the operating element 641 and the linking element 642 relative to the main body 61, and the limiting element 62 is kept from being engaged with the adjacent engaging structure 21.

Specifically, each of the retaining structures 69 may be a through hole formed in the body 61. Each auxiliary limit component 68 may include an auxiliary limit elastic member 681 and an auxiliary abutting member 682. The auxiliary limiting elastic member 681 is disposed in a through hole 641A of the operating member 641, one end of the auxiliary limiting elastic member 681 is fixed to the operating member 641, the other end of the auxiliary limiting elastic member 681 is fixed to the auxiliary abutting member 682, and one end of the auxiliary abutting member 682 protrudes from the operating member 641. When the auxiliary pushing member 682 exposed out of the operating member 641 is pushed by an external force, the auxiliary limiting elastic member 681 is pressed to generate an elastic restoring force, and when the auxiliary pushing member 682 is no longer pushed by the external force, the elastic restoring force generated by the auxiliary limiting elastic member 681 will restore the auxiliary pushing member 682 to a state where it is not pushed by the external force. In practical applications, the auxiliary limit elastic member 681 may be, for example, a telescopic spring.

Each unlocking assembly 67 includes an unlocking abutting member 671, an unlocking elastic member 672 and a housing 673. The housing 673 is provided in the body 61. The unlocking abutting piece 671 is arranged in the housing 673, two ends of the unlocking abutting piece 671 are exposed out of the housing 673, and the unlocking elastic piece 672 is arranged in the housing 673.

The unlocking propping piece 671 penetrates through the through hole (the limit structure 69), and one end of the unlocking propping piece 671 protrudes out of the body 61. One end of the unlocking elastic piece 672 is fixed to the body 61, and the other end of the unlocking elastic piece 672 is fixed to the unlocking abutting piece 671. The unlocking elastic member 672 may be, for example, a telescopic spring. The end of the unlocking abutting piece 671 exposed outside the body 61 is used for being pressed by a user, after the user presses the unlocking abutting piece 671 protruding outside the body 61, the unlocking abutting piece 671 moves relative to the body 61, and one end of the unlocking elastic piece 672 is driven by the unlocking abutting piece 671 to be in a stretched state.

As shown in fig. 21 and 23, when the operating assembly 64 is in the restricted state, the auxiliary abutting member 682 abuts against the side wall of the main body 61 for accommodating the operating element 641, and the auxiliary limiting elastic member 681 is in a pressed state. As shown in fig. 22 and fig. 24, when the operating element 64 is switched from the restricted state to the unlocked state and the operating element 641 is pressed toward the moving element 3, the auxiliary abutting element 682 moves along with the operating element 641 and correspondingly enters the through hole (the limiting structure 69) of the body 61, at this time, since the auxiliary abutting element 682 is no longer pressed, the auxiliary abutting element 682 pushes the unlocking abutting element 671 located in the through hole (the limiting structure 69) by the elastic restoring force generated by the auxiliary limiting elastic element 681.

When the operating element 641 is pressed, and the four linking elements 642 push against the two limiting elements 62, and accordingly when one end of each of the two limiting elements 62 is no longer engaged with the adjacent two engaging structures 21, the auxiliary elastic restoring element 66 is pushed against by the operating element 641 to be in a pressed state, in this state, one end of the auxiliary elastic restoring element 682 enters the through hole (the limiting structure 69) of the main body 61, and the operating element 641 cannot move relative to the main body 61, that is, the operating element 641 cannot move relative to the main body 61 under the elastic restoring force generated by pressing the auxiliary elastic restoring element 66, and the linking element 642 keeps pushing against the limiting elements 62, so that the limiting elements 62 are kept in a state of not being engaged with the adjacent engaging structures 21.

When the user presses the two operation members 641, and causes one end of each auxiliary abutting member 682 to correspondingly enter the through hole (the limiting structure 69) of the adjacent body 61, and the user moves the movable member 3 to the predetermined position, the user can expose one end of the body 61 by pressing the two unlocking abutting members 671, so that each auxiliary abutting member 682 moves relative to the body 61, and accordingly the unlocking abutting members 671 push the auxiliary abutting member 682 located in the through hole (the limiting structure 69) of the body 61 out of the through hole (the limiting structure 69) of the body 61.

When the part of the auxiliary propping element 682 in the through hole (the limiting structure 69) of the body 61 is pushed out of the through hole of the body 61, the operating element 641 is no longer limited and moves in a direction away from the body 61 under the action of the elastic restoring force of the auxiliary elastic restoring element 66, at this time, the four linking elements 642 move together with the operating element 641 and move in a direction away from the limiting elements 62, the two limiting elements 62 rotate relative to the body 61, and one end of each limiting element 62 is engaged with one of the adjacent engaging structures 21.

In short, after the user presses the two operation members 641, the movable member 3 can move to a desired position relative to the base plate 11 without continuously pressing the operation members 641, and then the user only needs to press the two unlocking abutting members 671, the two operation members 641 will automatically return to the non-pressed state, and the two limiting mechanisms 6 will again limit the movable range of the movable member 3 relative to the base plate 11.

It should be noted that, in the holding device 200 of the present embodiment, the plurality of engaging structures 21 are disposed on one side of each guiding member 5 facing another guiding member 5, so as to further reduce the overall lateral width of the holding device 200, and the holding device 200 can have better space utilization.

In summary, in one embodiment of the present disclosure, a user can simply press the two operation members to actuate the movable member relative to the base plate, and when the user moves the movable member to a desired position, the user only needs to press the operation members no longer, and the movable member is limited by the two limiting mechanisms and cannot move relative to the base plate; in another embodiment of the fixing device of the present application (including the unlocking component and the auxiliary limiting component), after the user presses the two operation components, the two limiting mechanisms will no longer limit the movement of the moving component relative to the base plate, and the user can move the moving component relative to the base plate without continuously pressing the operation component. Therefore, compared with the conventional holding device, the holding device of the application is more convenient and time-saving in operation, and related personnel can enable the movable part to move relative to the bottom plate only by simply pressing the operating part. Conversely, users of conventional retention devices require a significant amount of time to disassemble and assemble the nut to enable the movable member to move relative to the base plate.

The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, so that all equivalent technical changes made by using the contents of the specification and drawings of the present application are included in the protection scope of the present application.
