In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

The embodiment of the application provides a regulating frame for an optical device, which can be applied to any optical device, such as an optical device of a detection type, an optical device of an imaging type and the like. Optical devices are generally among the more sophisticated instruments that are required to provide a more precise optical path. However, in the manufacturing process, due to the influence of the machining accuracy of parts, the assembly process, or the like, the optical path of the optical device may be deviated, and thus the detection may not be realized.

Taking a detection optical device as an example, micro-raman is used as a nondestructive detection technology, and can perform micro-area detection and imaging test on a sample. However, due to the influence of the processing precision of parts or the assembly process, the laser emitted by the raman probe cannot vertically hit the sample to be measured after being reflected. After different microscope lenses are switched, when the microscope stage is adjusted up and down, laser spots cannot be kept consistent at the same point position, and even possibly run out of an imaging area.

The adjusting bracket provided by the embodiment of the present application is described below with reference to an application scenario of a raman probe.

As shown in fig. 1 and 2, the adjusting bracket includes: base 1, mount 2 and sleeve 4. Mounting hole 21 has been seted up to mount pad 2, and mount pad 2 is connected with base 1 through at least one first displacement adjustment mechanism 3, and first displacement adjustment mechanism 3 is used for adjusting mount pad 2 along the displacement of the relative base 1 of first direction. The sleeve 4 includes a first end 41 and a second end 42, the first end 41 is used for placing the optical device, the second end 42 is limited in the mounting hole 21 by a second displacement adjusting mechanism 5 and a third displacement adjusting mechanism 6, the second displacement adjusting mechanism 5 is used for adjusting the displacement of the sleeve 4 relative to the mounting base 2 along the second direction, and the third displacement adjusting mechanism 6 is used for adjusting the displacement of the sleeve 4 relative to the mounting base 2 along the third direction. The second direction, the third direction and the first direction are mutually vertical, and the second direction and the third direction are positioned on the same plane.

The first end 41 of the sleeve 4 may have a different structure for different optical devices, and the optical devices may be stably placed. Taking the raman probe as an example, since the raman probe is generally cylindrical, the first end 41 of the sleeve 4 may be provided with a cylindrical cavity 411, and the raman probe may be fixed within the cylindrical cavity 411.

In the embodiment of the present application, the number of the first displacement adjustment mechanism 3, the second displacement adjustment mechanism 5, and the third displacement adjustment mechanism 6 may be at least one. Wherein, through the relative base 1's of the adjustable mount pad 2 of first direction of first displacement adjustment mechanism 3 displacement, the direction of first direction can point perpendicular to base 1 (or mount pad 2), can make mount pad 2 deflect relative base 1 like this to drive sleeve 4 and deflect relative base 1, it is thus visible, first displacement adjustment mechanism 3 can adjust raman probe's laser outgoing angle. The sleeve 4 can be adjusted to move in a plane formed by a second direction and a third direction through the second displacement adjusting mechanism 5 and the third displacement adjusting mechanism 6 together, the second direction and the third direction can both refer to directions parallel to the base 1 (or the mounting base 2), and therefore the second displacement adjusting mechanism 5 and the third displacement adjusting mechanism 6 can realize the translation of the raman probe in the plane.

In other words, the first direction, the second direction and the third direction together form a three-dimensional space, for convenience of understanding, the first direction can be understood as a Z-axis of the three-dimensional space, and a plane formed by the second direction and the third direction can be understood as an XY plane of the three-dimensional space, so that the raman probe can be moved in the three-dimensional space by the first displacement adjusting mechanism 3, the second displacement adjusting mechanism 5 and the third displacement adjusting mechanism 6, and thus the laser emitting direction of the raman probe can be flexibly adjusted, and further the detection path of the raman probe can be flexibly adjusted.

Since the mount 2 needs to be moved in a first direction relative to the base 1, there may be a spacing between the mount 2 and the base 1, the magnitude of the deflection of the mount 2 relative to the base 1 being related to the spacing. Since the sleeve 4 is defined in the mounting hole 21, the position of the sleeve 4 in the XY plane is defined within the area defined by the mounting hole 21, and therefore, the amplitude of translation of the sleeve 4 in the XY plane is related to the size of the mounting hole 21. The size of the above-mentioned space and the size of the mounting hole 21 may be determined according to various factors, for example, the machining accuracy of the optical device, the assembling accuracy of the optical device, the length of the optical path, the accuracy that the optical path needs to satisfy, and the like. For example, if the machining accuracy of the optical device is larger than the theoretical accuracy, the deviation of the optical path of the optical device may be larger, which requires the optical device to move in a larger space, and thus the distance between the mounting base 2 and the base 1 and the size of the mounting hole 21 may be larger.

When the adjusting bracket of this application embodiment is used, at first can install the base 1 of adjusting bracket in the fuselage of micro-raman instrument earlier to make the raman probe stretch into in the sleeve 4, wherein, fifth through-hole 43 has been seted up to the lateral wall of sleeve 4, when the raman probe arrived the first end 41 of sleeve 4, can utilize fasteners 9 such as bolts to pass fifth through-hole 43, fix the raman probe. After the raman probe is fixed, the position of the laser emitted by the raman probe on the sample to be measured can be observed, and then the laser emitting direction of the raman probe can be adjusted through the first displacement adjusting mechanism 3, the second displacement adjusting mechanism 5 or the third displacement adjusting mechanism 6. Namely, by adjusting the first displacement adjustment mechanism 3, the mount 2 is deflected with respect to the base 1, that is, the laser emission angle of the raman probe is adjusted. The sleeve 4 can move along the second direction through the second displacement adjusting mechanism 5, and the sleeve 4 can move along the third direction through the third displacement adjusting mechanism 6, so that the Raman probe can move in a plane formed by the second direction and the third direction, namely, the Raman probe can move in a plane parallel to the mounting base 2. And repeatedly adjusting each displacement adjusting mechanism in such a way until the laser emitted by the Raman probe vertically hits on the sample to be measured.

The adjusting frame that this application provided can realize sleeve 4 at the displacement of first direction, second direction and third direction, that is to say realizes the removal of raman probe in three-dimensional space, and then realizes the regulation of raman probe's detection route.

In some embodiments, at least two first displacement adjustment mechanisms 3 may be provided to deflect the mount 2 relative to the base 1 in at least two directions. For example, two first displacement adjustment mechanisms 3 are provided, one of which is provided on the left side and the other of which is provided on the right side, and when performing an adjustment operation, the first displacement adjustment mechanism 3 on the right side can be held stationary, and the mount 2 is adjusted to be deflected to the left or right side by operating the first displacement adjustment mechanism 3 on the left side, and so on.

In the embodiment of the present application, the support 7 may be provided to adjust the deflection in as many directions as possible by the first displacement adjustment mechanism 3 as few as possible, and to improve the smoothness and continuity of the deflection angle during the deflection process, and the relative stability between the base 1 and the mount 2. The embodiment in which the support 7 is provided will be specifically described below.

As shown in fig. 3, the adjusting bracket further includes a supporting member 7, the supporting member 7 is located between the base 1 and the mounting base 2, and when the first displacement adjusting mechanism 3 adjusts the displacement of the mounting base 2 relative to the base 1, the mounting base 2 can deflect relative to the base 1 with the supporting member 7 as a fulcrum.

The support 7 may be a part whose surface is a circular arc surface, for example, the support 7 may be a spherical support 7, the support 7 may be a hemispherical support 7, the support 7 may be an ellipsoidal support 7, or the like. Thus, when the mounting base 2 deflects relative to the base 1 by taking the supporting piece 7 as a fulcrum, the supporting piece 7 can provide continuous and smooth deflection support for the mounting base 2, so that the accuracy and the stability of adjusting the laser emitting angle of the Raman probe can be improved.

The support 7 may be a separate component from the base 1 and the mounting base 2, or may be a component previously provided to the base 1 or the mounting base 2.

Illustratively, the supporting member 7 is a separate component from the base 1 and the mounting seat 2, the supporting member 7 is spherical, a first spherical groove for the supporting member 7 to be inserted into is arranged on the surface of the base 1 facing the mounting seat 2, a second spherical groove for the supporting member 7 to be inserted into is also arranged on the surface of the mounting seat 2 facing the base 1, a part of the supporting member 7 is inserted into the first spherical groove of the base 1, and a part of the supporting member 7 is inserted into the second spherical groove of the mounting seat 2.

Since the supporting member 7 is independent of the base 1 and the mounting seat 2, when the mounting seat 2 deflects relative to the base 1 with the supporting member 7 as a fulcrum, the supporting member 7 can roll along with the deflection of the mounting seat 2 in addition to providing continuous and smooth deflection support, and in this case, the supporting member 7 can be similar to a ball in a rolling bearing, so that the deflection flexibility of the mounting seat 2 can be improved to the maximum extent, and the degree of abrasion of the supporting member 7 can be reduced.

Of course, the supporting member 7 may be provided in advance on the base 1 or the base 1. For example, the supporting member 7 is pre-installed on the base 1, and the surface of the mounting seat 2 facing the base 1 is provided with a spherical groove for the supporting member 7 to be inserted into, and the supporting member 7 is inserted into the spherical groove. This is not specifically described as it is easily understood.

By providing the support 7, it is only necessary to provide a first displacement adjustment mechanism 3 to achieve the deflection of the mounting base 2 in two directions, as illustrated below:

the support 7 is arranged on the left side and a first displacement adjustment mechanism 3 is arranged on the right side, so that the mounting base 2 can be pivoted to the left or right by means of the first displacement adjustment mechanism 3.

When only one first displacement adjustment mechanism 3 is provided, the support 7, in addition to providing continuous and smooth yaw support, is also capable of spacing the base 1 from the mount 2, maintaining the proper spacing between the base 1 and the mount 2.

Two first displacement adjustment mechanisms 3 may also be provided on the basis of the support 7 to enable deflection of the mounting block 2 in at least two directions, thereby improving the stability of the deflection process of the mounting block 2. Regarding the positional relationship of the two first displacement adjustment mechanisms 3 and the support 7, the positional relationship may be determined according to the arm relationship of each first displacement adjustment mechanism 3 to the support 7. Namely, on the basis that the two first displacement adjusting mechanisms 3 and the support member 7 are distributed in a triangular manner, the positions of the two first displacement adjusting mechanisms 3 are designed according to two conditions that the moment arms from the two first displacement adjusting mechanisms 3 to the support member 7 are equal or unequal.

When the force arms from each first displacement adjusting mechanism 3 to the supporting member 7 are not equal, the supporting member 7 is located between the two first displacement adjusting mechanisms 3, and the two first displacement adjusting mechanisms 3 and the supporting member 7 can be irregularly arranged in a triangular manner.

When the force arms of each first displacement adjusting mechanism 3 to the supporting member 7 are equal, the two first displacement adjusting mechanisms 3 can be respectively arranged at two opposite sides of the base 1, and the supporting member 7 is arranged at the middle point of the connecting line of the two first displacement adjusting mechanisms 3, so that the two first displacement adjusting mechanisms 3 and the supporting member 7 are positioned on the same straight line, and the distance from each first displacement adjusting mechanism 3 to the supporting member 7 is equal.

In addition, the two first displacement adjusting mechanisms 3 and the support member 7 can be arranged in a triangular manner on the base 1, and a connecting line between the three forms an isosceles triangle. For example, when the base 1 has a rectangular shape, the support 7 may be disposed at an intersection area of two sides, and the two first displacement adjustment mechanisms 3 may be disposed at one side of the rectangle, respectively, so that the position connection lines of the support 7 and the two first displacement adjustment mechanisms 3 form an isosceles triangle. When the adjustment operation is performed, one of the first displacement adjustment mechanisms 3 may be held stationary, and by operating the other first displacement adjustment mechanism 3, the mount 2 may be smoothly deflected with the support 7 as a fulcrum.

The structure of the base 1 can be improved according to the isosceles triangle relationship between the connecting lines of the two first displacement adjusting mechanisms 3 and the supporting member 7. Such as designing the structure of the base 1 into an L-shaped structure. The following description will be made in the application scenario in which the displacement adjustment mechanism and the support 7 are applied to the L-shaped base 1.

The base 1 comprises a first arm 11 and a second arm 12 which are perpendicular to each other and are integrally formed, the two first displacement adjusting mechanisms 3 are respectively positioned in the corresponding areas of the first arm 11 and the second arm 12, and the supporting piece 7 is positioned in the transition area between the first arm 11 and the second arm 12.

In the embodiment shown in fig. 1, 3 and 4, one of the first displacement adjustment mechanisms 3 is located on the first arm 11, and the other first displacement adjustment mechanism 3 is located on the second arm 12, so that the one of the first displacement adjustment mechanisms 3 can be held stationary while performing the adjustment operation, and the mount 2 can be deflected about the support 7 by operating the other first displacement adjustment mechanism 3. Thus, the structure of the base 1 is simplified without affecting the relative stability between the mounting base 2 and the base 1.

In the embodiment of the present application, the adjustment principle of the first displacement adjustment mechanism 3 can be simply understood as that the deflection of the mounting base 2 is realized by adjusting the distance between the base 1 and the mounting base 2, and the embodiment thereof can be various. For example, the first displacement adjusting mechanism 3 may be a screw rod with an operating handle, the screw rod also penetrates through the base 1 and extends into the mounting seat 2, and the length of the screw rod extending into the mounting seat 2 is adjusted by rotating the operating handle to adjust the distance between the base 1 and the mounting seat 2; for another example, the first displacement adjustment mechanism 3 may be a clamp capable of adjusting a clamping width, the clamp clamps the base 1 and the mounting base 2, and the distance between the base 1 and the mounting base 2 can be adjusted by adjusting the clamping width of the clamp.

The following provides a first displacement adjustment mechanism 3 comprising a resilient connection 32.

As shown in fig. 3 to 5, each first displacement adjusting mechanism 3 includes a first adjusting member 31 and at least one elastic connecting member 32, one end of each elastic connecting member 32 is connected to the base 1, and the other end is connected to the mounting base 2, the first adjusting member 31 is a first adjusting rod having a first operating portion at one end, the first adjusting rod is sequentially connected to the base 1 and the mounting base 2 by threads, the screwing depth of the first adjusting rod into the mounting base 2 can be changed along with the rotation of the first operating portion to adjust the displacement of the mounting base 2 relative to the base 1 along the first direction, and the deformation degree of each elastic connecting member 32 can be changed along with the adjustment of the displacement.

The base 1 may be provided with a first threaded hole 17 for the first adjustment rod to pass through, and the mounting base 2 may be provided with a spherical hole 26 for the first adjustment rod to pass through, or may be provided with a second threaded hole. The first adjusting rod can first pass through the first threaded hole 17 of the base 1 and finally be screwed into the spherical hole 26 of the mounting base 2. Wherein, an elastic connecting piece 32 is further arranged between the base 1 and the mounting seat 2, and the elastic connecting piece 32 can be an elastic piece such as an elastic sheet and a compression spring. When the first operation part is rotated, the depth of the first adjusting rod screwed into the mounting base 2 can be adjusted, so that the deformation degree of the elastic connecting piece 32 between the base 1 and the mounting base 2 is constantly changed.

Take the example that the first operating part is rotated clockwise and the depth of the first adjusting rod screwed into the mounting base 2 is increased. In the initial state, the base 1 and the mounting base 2 are in an equidistant state, and the elastic connection 32 between the base 1 and the mounting base 2 is in a compressed state.

The first operation portion is rotated clockwise, and the first adjusting rod is driven to move through the first operation portion, so that the depth of the first adjusting rod screwed into the mounting base 2 is increased continuously, and the distance between the base 1 and the mounting base 2 is shortened continuously. In the whole process, the compression degree of the elastic connecting piece 32 is increased along with the shortening of the distance between the base 1 and the mounting seat 2. On the contrary, the first operation part is rotated anticlockwise, the first adjusting rod is continuously screwed out of the mounting base 2, and the distance between the mounting base 2 and the base 1 is continuously increased. As the distance between the two is increased, the elastic connecting member 32 is gradually changed from the compression state to the tension state by the tensile force applied by the mounting base 2.

The first adjusting member 31, the base 1 and the mounting base 2 are screwed, and an elastic connecting member 32 is disposed between the base 1 and the base 1. The principle that the threads are continuously arranged and the elastic connecting piece 32 is utilized, so that the whole adjusting process can be continuously carried out, and more accurate adjustment can be realized.

Further, as shown in fig. 3, the first displacement adjustment mechanism 3 further includes a locking member, such as a jack screw. The base 1 is provided with a fourth threaded hole 18 for cooperating with the locking member. The opening direction of the fourth screw hole 18 intersects the opening direction of the first screw hole 17, and the fourth screw hole 18 communicates with the first screw hole 17. When first regulation pole screw in mount pad 2 and reacing and predetermineeing the position, can be with jackscrew screw in base 1 in, fix first regulation pole through the jackscrew in order to avoid because of touching first operation portion, and lead to first regulation pole to revolve in mount pad 2 or screw out to drive sleeve 4 through first regulation pole and take place the motion, make sleeve 4 skew predetermineeing the position.

In some embodiments, the resilient coupling 32 is a tension spring. Base 1 is provided with first dead lever 16, and mount pad 2 is provided with second dead lever 25, and the one end of extension spring is connected with base 1 through first dead lever 16, and the other end passes through second dead lever 25 and is connected with mount pad 2.

In the initial state, the extension springs between the base 1 and the mounting seat 2 are all in a stretching state, and the base 1 and the mounting seat 2 are in an equidistant state. When the deflection angle of the mounting base 2 relative to the base 1 needs to be adjusted, a first adjusting rod of a certain first displacement adjusting mechanism 3 can be screwed into the mounting base 2. Because the tension spring is in a stretching state, the tension direction of the tension spring is opposite to the force application direction of the first adjusting rod,

therefore, the force application direction of the first adjusting member 31 is consistent with the restoring force direction of the tension spring, so that when the user rotates the first operating lever to screw the first adjusting member 31 into the mounting seat 2, the operating force required by the user is small under the restoring force of the tension spring, thereby providing convenience for the user to operate.

In some embodiments, the base 1 defines a first through hole 13, a first card slot 14, and a second through hole 15. The first through hole 13 is communicated with the second through hole 15 through a first clamping groove 14, and the first clamping groove 14 is arranged on one surface of the base 1, which is far away from the mounting seat 2.

Third through-hole 22, second draw-in groove 23 and fourth through-hole 24 have been seted up to mount pad 2, and third through-hole 22 communicates through second draw-in groove 23 and fourth through-hole 24, and second draw-in groove 23 sets up in the one side that mount pad 2 deviates from base 1. The first fixing rod 16 is embedded in the first slot 14, and both ends of the first fixing rod extend to the first through hole 13 and the second through hole 15, respectively, the second fixing rod 25 is embedded in the second slot 23, and both ends of the second fixing rod extend to the third through hole 22 and the fourth through hole 24, respectively. The number of the tension springs is two, and two ends of the two tension springs are respectively sleeved at two ends of the first fixing rod 16 and the second fixing rod 25.

As shown in fig. 2, 3 and 5, the base 1 and the mount 2 are spaced apart from each other. One side of the base 1, which is far away from the mounting seat 2, is provided with a first clamping groove 14, one end of the first clamping groove 14 is communicated with the first through hole 13, and the other end of the first clamping groove 14 is communicated with the second through hole 15. When the first fixing rod 16 is embedded in the first slot 14, two ends of the first fixing rod 16 are respectively located in the first through hole 13 and the second through hole 15. One side of the mounting seat 2 departing from the base 1 is provided with a second clamping groove 23, the second clamping groove 23 is similar to the first clamping groove 14 in structure, and two ends of the second clamping groove 23 are also respectively connected with a third through hole 22 and a fourth through hole 24 which are communicated with the clamping grooves. When the second fixing rod 25 is embedded in the second slot 23, two ends of the second fixing rod 25 are also respectively located in the third through hole 22 and the fourth through hole 24. The first fixing rod 16 and the second fixing rod 25 are connected through two tension springs, two ends of the two tension springs are respectively sleeved at two ends of the first fixing rod 16 and the second fixing rod 25, and end portions of the tension springs extend into the through holes and are sleeved at end portions of the fixing rods.

In the initial state, the tension spring between the base 1 and the mount 2 is in a stretched state. Because, the end of the tension spring is sleeved on the end of the first fixing rod 16. At this time, the direction of the tension spring on the first fixing lever 16 is perpendicular to the base 1 and faces the mount 2. Because the first fixing rod 16 is used for fixing the tension spring, in order to facilitate the installation and detachment of the first fixing rod 16, the first through hole 13 for accommodating the first fixing rod 16 may be disposed on a surface of the base 1 away from the mounting seat 2. Thus, the first fixing lever 16 can be fixed in the first through hole 13 by the tension of the first fixing lever 16 by the tension spring. So set up, be convenient for install and dismantle first dead lever 16 and extension spring. In addition, through holes communicated with the two ends of the first card slot 14 are arranged at the two ends of the first card slot, so as to accommodate the end part of the tension spring, namely the joint of the tension spring and the first card slot 14, and avoid the joint from interfering with other parts.

Regarding the second card slot 23, the third through hole 22, the fourth through hole 24, the second fixing rod 25, etc., the structure and operation thereof are similar to those of the first card slot 14, etc., and will not be described one by one.

In some embodiments, the second displacement adjustment mechanism 5 may include two second adjustment members 52, and the second adjustment members 52 may be threaded rods with operating handles.

The mounting base 2 can be provided with third threaded holes 27 for the screws to penetrate through, and the two third threaded holes 27 are distributed on two sides of the mounting hole 21 and arranged along the second direction. When the second adjusting member 52 is mounted, the end of the screw can pass through the mounting seat 2, reach the mounting hole 21 and finally abut against the outer side wall of the second end 42 of the sleeve 4. In this way, at the position of the adjustment sleeve 4 in the second direction, one of the second adjustment members 52 can be screwed in and the other second adjustment member 52 can be screwed out. I.e. the movement of the second end 42 in the second direction is effected by two second adjustment members 52.

In order to simplify the handling by the user and to facilitate the adjustment of the sleeve 4 by the user, the second displacement adjustment mechanism 5 may be provided with only one second adjustment member 52.

In some embodiments, as shown in fig. 2 and 3, the second displacement adjusting mechanism 5 includes a first elastic sheet 51 and a second adjusting member 52, the first elastic sheet 51 is clamped between the hole wall of the mounting hole 21 and the outer side wall of the second end 42, the second adjusting member 52 is a second adjusting rod having a second operating portion at one end, the second adjusting rod is in threaded connection with the mounting base 2, the second adjusting rod abuts against the outer side wall of the second end 42 through the mounting base 2, the depth of screwing the second adjusting rod into the mounting base 2 can be changed along with the rotation of the second operating portion, so as to adjust the displacement of the sleeve 4 relative to the mounting base 2 along the second direction, and the deformation degree of the first elastic sheet 51 can be changed along with the adjustment of the displacement.

As shown in fig. 2 and 3, the cross section of the second end 42 may be provided with a third locking groove (not shown) for locking the first resilient piece 51. When the sleeve 4 and the second displacement adjusting mechanism 5 are installed, the first elastic piece 51 may be first clamped in the third clamping groove, and then the second end 42 is inserted into the installation hole 21, so that the first elastic piece 51 is clamped between the hole wall of the installation hole 21 and the outer side wall of the second end 42. The second adjustment lever is then inserted into the third threaded hole 27 of the mounting base 2 and the end of the second adjustment lever abuts against the outer side wall of the second end 42 through the third threaded hole 27.

Of course, the first resilient piece 51 may also be disposed independently of the second end 42, i.e. the middle of the first resilient piece 51 is adapted to the outer sidewall of the second end 42. When the first elastic sheet 51 is installed, the first elastic sheet 51 may be placed in the installation hole 21, and two ends of the first elastic sheet 51 may abut against the hole wall of the installation hole 21. Then, the second end 42 is placed in the mounting hole 21, and one side surface of the first elastic sheet 51 is attached to the outer side wall of the second end 42, and the other side surface of the first elastic sheet 51 is abutted to the hole wall of the mounting hole 21.

Take the example that the depth of the second adjusting rod screwed into the mounting base 2 is increased continuously. The second operation part is rotated to enable the second adjusting rod to move along the second direction, at the moment, the second end 42 of the sleeve 4 is driven by the second adjusting rod to be continuously close to the hole wall of the mounting hole 21, and the deformation degree of the first elastic sheet 51 arranged between the hole wall of the mounting hole 21 and the outer side wall of the second end 42 is continuously intensified.

Therefore, the adjustment of the sleeve 4 in the second direction can be realized by utilizing the first elastic sheet 51 and the second adjusting rod which are matched, and in addition, only the second operation part of the second adjusting rod needs to be rotated during operation, so that the operation mode is simplified.

The third displacement adjustment mechanism 6 and the second displacement adjustment mechanism 5 provided by the application have similar structures, and the third displacement adjustment mechanism 6 also comprises a second elastic sheet and a third adjustment rod. It should be noted that the structures of the first elastic sheet 51 and the second adjusting lever can be both applied to the second elastic sheet and the third adjusting lever. In the embodiment of the present application, only the first elastic sheet 51 and the second adjusting lever are taken as an example for description, and the second elastic sheet and the third adjusting lever are not separately described.

It will be readily appreciated that the mounting socket 2 is also provided with a plurality of fifth threaded apertures 28 adapted to receive the locking members. A locking member may be threaded into the fifth threaded aperture 28 to secure the second and third adjustment levers. So as to prevent the sleeve 4 from continuing to move and further deviating from the preset position due to misoperation or touch after the sleeve 4 moves to the preset position.

The cross section of the second end 42 provided by the present application is a polygon, and two tangent planes of the polygon arranged adjacently may be perpendicular to each other. When the second adjusting rod and the third adjusting rod are abutted against the second end 42, the end surfaces of the adjusting rods are abutted against one surface of the polygon. In this way, the contact area between the adjustment lever and the second end 42 can be increased, thereby improving the stability when the adjustment lever abuts against the second end 42.

As shown in fig. 2, 5 and 6, in one embodiment, the second end 42 has an outer diameter greater than an outer diameter of the first end 41, and the second end 42 has an end surface facing the first end 41. The mounting hole 21 is provided with a step surface 211 which is perpendicular to the hole wall of the mounting hole 21 and is far away from the base 1, and the end surface of the second end 42 is abutted against the step surface 211.

When the sleeve 4 is mounted, the first end 41 of the sleeve 4 may first pass through the mounting seat 2 until the end surface of the second end 42 abuts against the step surface 211. The second end 42 is then constrained within the mounting hole 21 by the second displacement adjustment mechanism 5 and the third displacement adjustment mechanism 6. Since the end surface of the second end 42 is always in contact with the step surface 211, the second end 42 can always move smoothly in the plane of the step surface 211, that is, in the same plane formed by the second direction and the third direction.

In one embodiment, the base 1 has an escape space, which communicates with the mounting hole 21, through which the first end 41 of the sleeve 4 extends to protrude from the surface of the base 1 facing away from the mounting seat 2.

For example, when the structure of the base 1 is a square structure, the base 1 may have an avoidance space formed by a through hole formed in the middle of the base 1.

Of course, the structure of the base 1 may be triangular or the like. For example, in the embodiment shown in fig. 1 and 4, the base 1 may have an L-shaped structure, an escape space may be opened at the intersection of the first arm 11 and the second arm 12, and the base 1 is recessed inward toward the side wall of the sleeve 4 to form an arc surface matching the outer side wall of the sleeve 4. First end 41 based on sleeve 4 is outstanding in the surface that base 1 deviates from mount pad 2, and first end 41 is equipped with fastener 9 again and fixes the lens, sets up and dodges the space, can avoid base 1 and fastener 9 to interfere each other, provides operating space for fastener 9. In addition, the L-shaped structure can also reduce the weight of the base 1 and reduce the difficulty in mounting the base 1.

Further, the structure of the mounting base 2 may be a square structure with a cut-away corner, and the cut-away portion may be disposed on the side of the mounting base 2 not connected to the elastic connection member 32. The weight of the mounting seat 2 is reduced by cutting off a part of the structure. Wherein, the outer contour dimension of the mounting seat 2 can be slightly smaller than that of the base 1. Thus, a certain operation space is provided for the mounting base 2, and the mounting base 2 is prevented from interfering with the base 1 when deflecting relative to the base 1. It will be readily understood that the outer dimensions of the mounting seat 2 may also be equal to slightly larger than the outer dimensions of the base 1, only to ensure that the mounting seat 2 can be deflected relative to the base 1.

In order to save the installation space of the base 1, a plurality of fixing holes arranged at intervals can be arranged on the side surface of the base 1 deviating from the avoiding space, namely the cambered surface, and the base 1 can be installed at a preset position through a fixing piece matched with the fixing holes.

In addition, the adjusting bracket further comprises an end cover 8, and the end cover 8 is provided with a sixth through hole 81 and an opening 82 communicated with the mounting hole 21. The locking member 83 is inserted into the sixth through hole 81 of the end cap 8 and the sixth screw hole 29 of the mounting seat 2. And will install in the one side that the mount pad 2 deviates from base 1, wherein, the aperture of trompil 82 is less than the cross-section external diameter of the second end 42 of sleeve 4, so, can pass end cover 8 when supplying the camera lens, further fix sleeve 4, avoid sleeve 4 to deviate from in the mounting hole 21.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
