In other words, the size of the damping force feedback is controlled by controlling the difference of the abutting degree between the abutting surface on the abutting part and the rotating shaft, so that the trigger key device can adjust the size of the provided damping force feedback, and the user experience is improved. Meanwhile, when different resistance feedback effects are not required to be generated by the trigger key device, the driving piece of the abutting component can drive the abutting piece to move, so that the abutting surface on the abutting piece is separated from the rotating shaft in the trigger key and the friction damping force cannot be applied to the rotating shaft. When the key body is pressed, the key body is not influenced by the butt of the butt surface on the butt piece, so that the effect of 'no change of hand feeling' is realized. Therefore, the trigger key device can switch states between providing different damping force feedbacks and not having dynamic damping force feedbacks, so that the trigger key device can be used according to specific actual requirements, and the use convenience of the trigger key device is improved.

And because the damping force feedback that trigger button device in this scheme provided leans on the butt face on the butt piece and the frictional force between the axis of rotation to produce for can adopt the material that coefficient of friction is higher relatively to make butt face and/or axis of rotation, with the frictional force between increase butt face and the axis of rotation, and then make the size of the damping force feedback that trigger button device can provide also relatively great. In this case, the restriction of the magnitude of the driving force of the driving member on the magnitude of the damping force fed back by the trigger key device can be reduced, so that the trigger key device can generate a large damping force feedback even when a small driving member is used. When a smaller driving piece is adopted, the occupation of the trigger key device on the space can be greatly reduced, so that the overall size of the trigger key device is favorably and greatly reduced, and the requirement of miniaturization of the current consumer electronic equipment can be met. Meanwhile, when the volume of the driving piece is relatively small, the possibility of interference between the driving piece and other objects in the trigger key device can be reduced in the installation process, and therefore convenience and safety of installation of the driving piece are improved.

The invention provides a trigger key device.

Referring to fig. 1, fig. 2 and fig. 3, in an embodiment of the present invention, the trigger button device includes a mounting base 10, a trigger button 30 and an abutting assembly 50. The trigger key 30 comprises a rotating shaft 31 and a key body 33, the rotating shaft 31 is rotatably arranged on the mounting seat 10, and the key body 33 is connected with the rotating shaft 31; the abutting assembly 50 comprises a driving piece 51 and an abutting piece 53, the driving piece 51 is arranged on the mounting seat 10, the abutting piece 53 is connected with the driving piece 51, and the abutting piece 53 is provided with an abutting surface 531; the driving member 51 can drive the abutting member 53 to move so that the abutting surface 531 abuts against or separates from the rotating shaft 31, and when the abutting surface 531 abuts against the rotating shaft 31, the driving member 51 drives the abutting member 53 to change the pressure between the abutting surface 531 and the rotating shaft 31. .

In one embodiment of the present invention, the mounting base 10 may be used to mount and carry the trigger button 30, the abutment assembly 50, etc., so that the various components of the trigger button device may be assembled into a single unit to facilitate its disposable mounting in an electronic device. The projection of the mounting base 10 on the horizontal plane may be square or rectangular, so that the shape is regular and the mounting base is convenient to machine. Of course, the present application is not limited to this, and the projection of the mounting base 10 on the horizontal plane may also be a circle or other shapes, and may be specifically configured adaptively according to the mounting position and space in the electronic device. The forming form of the mounting seat 10 may be a plate-shaped structure, or a frame structure formed by enclosing a plate body and/or a column body, the forming form of the mounting seat 10 is not specifically limited in the present application, and the mounting and the bearing of the trigger button 30 and the abutting assembly 50 can be realized. The pivot shaft 31 of the trigger button 30 may be adapted to be pivotally coupled to the mount 10 such that the trigger button 30 may be pivoted relative to the mount 10 when pressed by a user. The key body 33 may be used to provide an operating position for a user to apply force by pressing the trigger key 30. The key body 33 and the rotating shaft 31 may be an integral structure to increase the stability of the connection between the two. Of course, the key body 33 and the rotary shaft 31 may be provided separately and fixed by a connection structure such as a snap-fit connection or a screw connection. The driving member 51 of the abutment assembly 50 may be used to provide power to drive the abutment member 53 to move to achieve the abutment and disengagement of the abutment surface 531 on the abutment member 53 with the rotation shaft 31. Meanwhile, when the contact surface 531 contacts the rotating shaft 31, the driver 51 may drive the contact member 53 to change the pressure between the contact surface 531 and the rotating shaft 31, thereby adjusting the magnitude of the frictional resistance force between the contact surface 531 and the rotating shaft 31. The driving member 51 can drive the abutment member 53 to rotate, so as to enable the abutment member 53 to approach or separate from the rotating shaft 31. Of course, the driving member 51 may also drive the abutment member 53 to slide so as to move the abutment member 53 closer to or away from the rotating shaft 31. The contact piece 53 may be configured to contact the rotating shaft 31 and apply a frictional damping force thereto when the contact piece 53 is driven by the driver 51, or to be disengaged from the rotating shaft 31 and cancel the frictional damping force applied thereto. The contact surface 531 of the contact piece 53 may be a circumferential surface that contacts the rotating shaft 31, or may be an end surface that contacts the rotating shaft 31 in the axial direction.

In the use process of the trigger key device of the technical scheme of the invention, when the trigger key device is required to generate different resistance feedback effects, the driving piece 51 of the abutting component 50 can drive the abutting piece 53 to move, so that the abutting surface 531 on the abutting piece 53 is abutted with the rotating shaft 31 in the trigger key 30 to apply friction damping force to the rotating shaft 31. The key body 33 is fixedly connected to the rotating shaft 31, and when the key body 33 is pressed, the frictional damping force applied to the rotating shaft 31 by the abutting surface 531 of the abutting member 53 is transmitted to the key body 33 and sensed by the user. When the contact surface 531 contacts the rotating shaft 31, the driver 51 can drive the contact piece 53 to change the pressure between the contact surface 531 and the rotating shaft 31. In other words, the control controls the magnitude of the damping force feedback according to the difference of the abutting degree between the abutting surface 531 on the abutting piece 53 and the rotating shaft 31, thereby realizing that the trigger key device can adjust the magnitude of the provided damping force feedback and improve the user experience. Meanwhile, when there is no need for the trigger button device to generate different resistance feedback effects, the driving member 51 of the abutment assembly 50 can drive the abutment member 53 to move, so that the abutment surface 531 on the abutment member 53 is separated from the rotation shaft 31 in the trigger button 30 and the frictional damping force cannot be applied to the rotation shaft 31. At this time, when the key body 33 is pressed, the contact of the contact surface 531 of the contact piece 53 is not affected, and the effect of "no change feeling" is achieved. Therefore, the trigger key device can switch states between providing different damping force feedbacks and not having dynamic damping force feedbacks, so that the trigger key device can be used according to specific actual requirements, and the use convenience of the trigger key device is improved.

In addition, since the damping force feedback provided by the trigger key device in this embodiment is generated by the friction force between the abutting surface 531 on the abutting member 53 and the rotating shaft 31, the abutting surface 531 and/or the rotating shaft 31 may be made of a material having a relatively high friction coefficient (wherein, only the entire abutting member 53 or a local region of the abutting member 53 where the abutting surface 531 is formed may be made of a material having a relatively high friction coefficient, only the entire rotating shaft 31 or a local region of the abutting member 31 where the rotating shaft 31 abuts against the abutting surface 531 may be made of a material having a relatively high friction coefficient, or the entire abutting member 53 or a local region of the abutting member 53 where the abutting surface 531 is formed may be made of a material having a relatively high friction coefficient together with the entire rotating shaft 31 or the local region of the abutting member 31 where the rotating shaft 31 abuts against the abutting surface 531, and the material having a relatively high friction coefficient may be polycarbonate or polyvinyl chloride, etc.), so as to increase the friction force between the abutting surface 531 and the rotating shaft 31, and further increase the magnitude of the damping force feedback that can be provided by the trigger key device. In this case, the restriction of the magnitude of the driving force of the driving member 51 to the magnitude of the damping force fed back from the trigger button device can be reduced, so that the trigger button device can generate a large damping force feedback even when the driving member 51 is small in size. Moreover, the use of a smaller driving member 51 can greatly reduce the space occupied by the trigger key device, thereby greatly reducing the overall size of the trigger key device and meeting the current demand for miniaturization of consumer electronic devices. Meanwhile, when the volume of the driving member 51 is relatively small, the possibility of interference with other objects in the trigger button device during the installation process can be reduced, thereby being beneficial to improving the convenience and safety of the installation of the driving member 51.

Referring to fig. 1 and fig. 3, in an embodiment of the present invention, the driving element 51 is a motor 511, the abutting element 50 further includes a transmission element 55, the transmission element 55 is connected to the motor 511 and the abutting element 53 in a transmission manner, and the motor 511 drives the transmission element 55 to rotate so as to drive the abutting element 53 to slide.

It will be appreciated that the driving member 55 is driven to rotate by the motor 511, and then the driving member 55 drives the abutting member 53 to slide so as to make the abutting surface 531 close to or away from the rotation shaft 31. Therefore, the rotation motion of the driving element 51 can be converted into the linear motion of the abutting element 53, and the rotation motion enables only the output shaft of the driving element 51 to rotate without performing telescopic motion along the sliding direction of the abutting element 53, so that the situation that the driving stroke of the driving element 51 needs to occupy a relatively large space on the mounting seat 10 is avoided, a sliding space for the driving element 51 to slide is not required to be arranged on the mounting seat 10, and the overall size of the trigger key device is further reduced. When the driving member 51 is the motor 511, the abutting surface 531 on the abutting member 53 and the rotating shaft 31 generate damping force by friction, and at this time, there is no direct connection relationship between the rotating shaft 31 and the motor 51, and only the motor 511 needs to slide the abutting member 53 by the transmission member 55 for a certain distance and then abut against the rotating shaft 31 by the abutting member 53, so that the motor 511 does not need to be in a locked-rotor working state for a long time, and further the risk that the motor 511 is burned due to long-time locked-rotor can be avoided, so as to prolong the service life of the driving member 51. During the sliding process of the contact piece 53, the contact piece 53 may slide in a direction away from the rotating shaft 31 to realize the contact between the contact surface 531 and the rotating shaft 31, or the contact piece 53 may slide in a direction close to the rotating shaft 31 to realize the contact between the contact surface 531 and the rotating shaft 31. That is, the contact piece 53 may generate a frictional damping force by applying a tensile force to the rotating shaft 31 and making contact therewith, or may generate a frictional damping force by applying a pushing force to the rotating shaft and making contact therewith. In addition, it should be noted that the present application is not limited thereto, and in other embodiments, the driving member 51 may be an air cylinder. At this time, the abutment 53 may be connected to the telescopic end of the cylinder and be slid in a direction approaching or separating from the rotation shaft 31 by the cylinder driving. Because the cylinder has a telescopic stroke, the mounting seat 10 can be correspondingly arranged to be relatively larger so as to adapt to the telescopic movement of the cylinder.

Referring to fig. 1, fig. 2 and fig. 3, in an embodiment of the present invention, the transmission member 55 is a threaded rod 551, and one end of the threaded rod 551 is connected to the motor 511; a threaded hole 533 is formed in the abutting part 53, the threaded hole 533 extends along the sliding direction of the abutting part 53, and one end of the threaded rod 551, which is away from the motor 511, is inserted into the threaded hole 533.

It will be appreciated that the transmission member 55 is provided as a threaded rod 551, and the abutment member 53 is provided with a threaded hole 533, which is driven to rotate by the motor 511 to bring the abutment into sliding movement by the threaded rod 551. The transmission member 55 and the abutting member 53 are inserted and fixed, so that the installation is more compact and the occupied space is reduced, thereby being beneficial to further reducing the whole volume of the trigger key device. Moreover, the screw rod 551 and the screw hole 533 are driven in a matching manner, which has the advantages of stability and reliability, so that the stability of the abutting piece 53 in the sliding process and the accuracy of sliding to the preset position can be improved, and when the friction resistance of the trigger button device to the user is adjusted to be fed back, the abutting piece 53 can be stably stopped and limited to stably abut against the rotating shaft 31. In addition, the matching of the threaded rod 551 and the threaded hole 533 has a relatively strong self-locking function, so that the abutting surface 531 on the abutting piece 53 can be stably abutted against the rotating shaft 31 to generate corresponding friction damping force only by driving the abutting piece 53 to reach a specified position by the motor 511 through the threaded rod 551, the motor 511 is not required to stop in a working state to limit the rotating shaft 31, and the risk of burning due to rotation blockage limitation is further avoided. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the transmission member 55 may also include a gear and a rack, the gear is sleeved on the motor 511, and the gear is engaged with the gear and further connected with the abutting member 53. At this time, the gear is driven by the motor 511 to rotate, so as to drive the rack engaged therewith to slide, and further drive the abutting member 53 to slide.

Referring to fig. 2 and fig. 3, in an embodiment of the present invention, the abutting member 53 includes a connecting rod 535 and an abutting plate 537, and a threaded hole 533 is formed in the connecting rod 535; the contact plate 537 is connected to an end of the connecting rod 535 facing away from the motor 511, and the contact plate 537 is formed with a contact surface 531.

It can be understood that the connecting rod 535, because of the rod-like structure, is convenient to form the threaded hole 533 therein, thereby improving the convenience of forming the threaded hole 533 on the abutting member 53, and meanwhile, ensuring that the abutting member 53 has certain strength to facilitate prolonging the service life of the abutting member 53. The abutting plate 537 has a plate-like structure, so that the volume thereof can be relatively small, and when the abutting surface 531 abuts against the rotating shaft 31, the possibility of collision and interference between the abutting piece 53 and the mount base 10 or the key main body 33 can be reduced. The cross section of the connecting rod 535 (the cross section in the extending direction of the connecting rod 535) of the abutting member 53 may be square or rectangular, so that the shape of the connecting rod 535 is regular and the processing is convenient. Of course, the cross section of the connecting rod 535 (the cross section in the extending direction of the connecting rod 535) may be circular or other shape, etc. The plane on which the contact plate 537 of the contact piece 53 is located may be perpendicular to the axial direction of the rotating shaft 31 or may be parallel to the axial direction of the rotating shaft 31, and the contact surface 531 may be configured to contact the rotating shaft 31. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the whole abutting member 53 may be formed by a rod-shaped structure.

Referring to fig. 2 and 3, in an embodiment of the present invention, the abutting member 53 is provided with a sliding hole 539, the sliding hole 539 extends in a moving direction of the abutting member 53, one of two opposite hole walls of the sliding hole 539 in the moving direction of the abutting member 53 is formed as an abutting surface 531, and the rotating shaft 31 passes through the sliding hole 539.

It can be understood that, by inserting the rotating shaft 31 through the sliding hole 539 and forming the hole wall of the mounting hole as the abutment surface 531 that abuts against the rotating shaft 31, the two are not easily separated from each other, which is advantageous for ensuring the stability of the abutment. Meanwhile, the arrangement makes the rotating shaft 31 and the abutting piece 53 distributed more compactly, so as to reduce the occupied space, thereby being beneficial to further reducing the whole volume of the trigger key device. Wherein, when the abutment 53 comprises the connecting rod 535 and the abutment plate 537, the end of the abutment plate 537 facing away from the connecting rod 535 is provided with a sliding hole 539. Of course, the present application is not limited thereto, and in other embodiments, the surface of the abutment plate 537 facing away from the connecting rod 535 is formed as the abutment surface 531.

Referring to fig. 2 and fig. 3, in an embodiment of the present invention, the abutting surface 531 is an arc surface structure.

It is understood that, since the side circumferential surface of the rotating shaft 31 is a curved surface, the abutting surface 531 is configured as a curved surface structure. The contact between the two members can be made more close, so that the contact piece 53 can be brought into stable contact with the rotating shaft 31 to generate a stable frictional damping force. Meanwhile, since the processing tool is generally of a spherical structure, the abutting surface 531 of a cambered surface structure is also convenient for processing and forming. The sliding hole 539 may be a kidney-shaped hole so that both hole walls in the sliding direction of the abutment 53 have a curved surface structure, thereby further improving the convenience of machining. Of course, it should be noted that the present application is not limited thereto, and the sliding hole 539 may be formed only by the abutment surface 531 being a curved surface structure, and the other hole walls being all planar structures. Alternatively, when the contact surface 531 is also formed in a flat configuration, the slide hole 539 may be a rectangular hole.

Referring to fig. 3, in an embodiment of the present invention, a distance between two hole walls of the sliding hole 539 perpendicular to the moving direction of the abutting member 53 is the same as the diameter of the rotating shaft 31.

It is understood that the rotating shaft 31 is abutted by both hole walls of the sliding hole 539 in the direction perpendicular to the moving direction of the abutment 53, so that the abutment 53 is driven by the driver 51. The abutting piece 53 can be correspondingly guided through the abutting matching of the rotating shaft 31 and the two hole walls of the sliding hole 539 in the direction perpendicular to the moving direction of the abutting piece 53, so that corresponding guide structures do not need to be additionally arranged on the mounting base 10 and the abutting piece 53, and the structure of the trigger key device is facilitated to be simplified, the manufacturing cost is reduced, and the whole volume is further reduced. Of course, when the distance between the walls of the sliding hole 539 perpendicular to the moving direction of the abutting member 53 is larger than the diameter of the rotating shaft 31, a sliding rail may be provided on the mounting base 10, and a sliding block may be correspondingly provided on the abutting member 53, and the sliding block is slidably connected to the sliding rail to guide the sliding of the abutting member 53.

Referring to fig. 3, in an embodiment of the present invention, the distance between two opposite surfaces of the abutment plate 537 that are not penetrated by the sliding hole 539 decreases in a direction in which the abutment plate 537 faces away from the connecting rod 535.

It is understood that the distance between the two opposite surfaces of the abutment plate 537 which are not penetrated by the sliding hole 539 is reduced to further reduce the volume of the abutment plate 537, so that when the abutment surface 531 abuts against the rotation shaft 31, the possibility of collision interference between the abutment member 53 and the mounting seat 10 or the key body 33 can be further reduced. The distance between two opposite surfaces of the abutting plate 537 may be gradually decreased, or may be recessed to form a step or at least two steps only at the middle position of the abutting plate 537. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the distance between the two opposite surfaces of the abutment plate 537 that are not penetrated by the sliding hole 539 may be a fixed value in the direction in which the abutment plate 537 faces away from the connecting rod 535.

In one embodiment of the present invention, the abutment plate 537 and the connecting rod 535 are of a unitary construction.

It can be understood that the abutting plate 537 and the connecting rod 535 are integrally arranged, so that the connecting strength of the abutting plate 537 and the connecting rod 535 at the joint can be enhanced, and the overall strength of the abutting rod is further improved, so that the abutting part 53 can stably abut against the rotating shaft 31. Meanwhile, by such an arrangement, the abutting plate 537 and the connecting rod 535 can be manufactured by integral molding, so that the processing processes of the abutting plate 537 and the connecting rod 535 are simplified, and the production efficiency of the abutting piece 53 is improved. Of course, the present application is not limited thereto, and in other embodiments, the abutting plate 537 and the connecting rod 535 may be separately disposed, and then integrally formed by assembling through glue adhesion, screw connection, snap connection, magnetic attraction fixation, or the like.

Referring to fig. 1, fig. 2 and fig. 4, in an embodiment of the present invention, the rotating shaft 31 includes a rotating section 311 and a friction increasing section 315, the rotating section 311 is rotatably disposed on the mounting base 10; the friction increasing section 315 is connected to the rotating section 311; the key body 33 is connected to the rotating section 311, when the driver 51 drives the contact member 53 to move, the contact surface 531 contacts with or separates from the friction increasing section 315, and when the contact surface 531 contacts with the friction increasing section 315, the driver 51 drives the contact member 53 to change the pressure between the contact surface 531 and the friction increasing section 315.

It can be understood that the friction increasing section 315 can increase the frictional damping force generated by the abutting member 53 when abutting against the abutting member, thereby improving the resistance feedback effect of the trigger key device on the user. Meanwhile, the arrangement also enables the driving element 51 to adopt the motor 511 with smaller torque force, namely the motor 511 with smaller volume, thereby further avoiding the increase of the occupied space of the driving element 51 due to the need of adopting the motor 511 with larger torque force. That is, the motor 511 with a smaller size can be used as the motor 511, so that the overall size of the trigger button device is reduced, and the installation convenience of the motor 511 is improved due to the influence of the space limitation on the installation base 10. The friction increasing section 315 may be made of a material with a relatively high friction coefficient (e.g., polycarbonate or polyvinyl chloride), or only the surface of the friction increasing section 315 may be made of a material with a relatively high friction coefficient (e.g., polycarbonate or polyvinyl chloride), or the surface of the friction increasing section 315 may be provided with a plurality of protrusions to form a relatively rough surface. In addition, when the rotating shaft 31 includes the rotating section 311 and the friction increasing section 315, the friction increasing section 315 passes through the sliding hole 539.

Referring to fig. 2 and 4, in an embodiment of the invention, a limiting rib 313 is disposed on a lateral peripheral surface of the rotating section 311, a limiting groove 331 is disposed at a position of the key body 33 corresponding to the limiting rib 313, and the limiting rib 313 is embedded in the limiting groove 331.

It can be understood that, by embedding the limiting rib 313 into the limiting groove 331, the abutting area 531 between the rotating section 311 and the key body 33 can be increased, thereby being beneficial to improving the stability of the connection between the rotating shaft 31 and the key body 33. The limiting rib 313 may be disposed in a long strip shape and extend along the axial direction of the rotating section 311, so as to further increase the contact area between the rotating section 311 and the key body 33. Of course, in other embodiments, the limiting rib 313 may be disposed in a block shape. The number of the position limiting ribs 313 embedded may be multiple, and the number of the position limiting ribs 313 embedded may be distributed at intervals along the circumference of the rotating section 311, and then the position limiting grooves 331 may be correspondingly provided in multiple numbers. Of course, the present application is not limited thereto, and in other embodiments, the rotating section 311 and the key body 33 may be connected by screws.

It will be appreciated that the number of the rotation sections 311 is two such that the friction increasing section 315 is located in the middle. The contact surface 531 of the contact member 53 can contact the friction increasing section 315, so as to apply a uniform contact force to the rotating shaft 31, so that the key body 33 can receive a uniform frictional damping force at two opposite ends of the rotating shaft 31 when being operated by a user. Furthermore, the rotating shaft 31 is rotatably connected to the mounting seat 10 through both of the rotating sections 311, and the connecting force of the rotating shaft 31 to the mounting seat 10 is also increased, thereby improving the stability of the installation of the rotating shaft 31 on the mounting seat 10. Meanwhile, the key body 33 may also be connected to the two rotating sections 311, so that the connection between the key body 33 and the rotating shaft 31 is also increased. When the number of the rotation sections 311 is two, only one rotation section 311 may be provided with the limiting rib 313, and certainly, both the rotation sections 311 may be provided with the limiting ribs 313. In addition, it should be noted that the present application is not limited thereto, and in other embodiments, the number of the rotating section 311 and the friction increasing section 315 may be only one; alternatively, the number of the rotation sections 311 has one, and the number of the friction-increasing sections 315 has two and is respectively located at opposite ends of the rotation sections 311.

In one embodiment of the present invention, the rotating section 311 and the friction increasing section 315 are an integral structure.

It can be understood that the rotation section 311 and the friction increasing section 315 are integrated, so as to enhance the connection strength between the two at the connection point, and further improve the overall strength of the rotation shaft 31, so as to prolong the service life of the rotation shaft 31. Meanwhile, the rotating section 311 and the friction increasing section 315 can be manufactured by integral molding, so that the processing processes of the rotating section and the friction increasing section are simplified, and the production efficiency of the abutting piece 53 is improved. Of course, the present application is not limited thereto, and in other embodiments, the rotating section 311 and the friction increasing section 315 may be separately disposed, and then are assembled into a whole by glue, screw, snap, or magnetic fastening.

Referring to fig. 2 and 3, in an embodiment of the present invention, the diameter of the rotating section 311 is the same as the diameter of the friction increasing section 315.

It can be understood that the diameter of the rotating section 311 and the diameter of the friction-increasing section 315 are the same, so that the peripheral surface of the rotating shaft 31 has consistency, and the shape of the rotating shaft 31 is more regular and is easier to manufacture. Meanwhile, the arrangement is such that when the rotating shaft 31 is installed, one end of the rotating shaft can penetrate through the installation seat 10 and the key body 33, thereby improving the convenience of installing the rotating shaft 31. Of course, the application is not limited thereto, and in other embodiments, the diameter of the rotating section 311 may be larger or smaller than the diameter of the friction increasing section 315.

At this time, the one end of the contact piece 53 having the contact surface 531 is slidable in the space when the contact piece 53 is driven by the driver 51. That is, the space formed between the key body 33 and the mounting seat 10 avoids the movement of the abutting piece 53, thereby reducing the possibility of interference between the abutting piece 53 and the key body 33 during the driving process of the driven member 51. When the number of the rotation sections 311 of the rotation shaft 31 is one, the number of the first coupling lugs 333 coupled to the rotation sections 311 may be one. When the number of the rotation sections 311 of the rotation shaft 31 is two, the number of the first coupling lugs 333 to be coupled to the two rotation sections 311 is two. The rotating section 311 is provided with a limiting rib 313, and the first connecting lug 333 is provided with a limiting groove 331 on the hole wall of the first rotating hole 337 for the rotating section 311 to pass through. When the key body 33 is not provided with the first coupling lug 333, the rotation section 311 of the rotation shaft 31 can be directly inserted from a side wall surface of the key body 33. Or the surface of the key body 33 facing the mounting seat 10 is directly connected to the rotating section 311 of the rotating shaft 31.

The second engaging lug 11 may be provided with a second rotating hole 111 for rotatably connecting the rotating section 311 of the rotating shaft 31 thereto. When the number of the rotation sections 311 of the rotation shaft 31 is one, the number of the second engaging lugs 11 rotatably coupled to the rotation sections 311 may be one. When the number of the rotation sections 311 of the rotation shaft 31 is two, the number of the second engaging lugs 11 rotatably connected to the two rotation sections 311 is two. Further, the two second engaging lugs 11 may be located between the two first engaging lugs 333, so that the key body 33 and the mounting seat 10 may be distributed more orderly. When the mounting seat 10 is not provided with the second engaging lug 11, the mounting seat 10 may be recessed to form a groove, and the rotating section 311 of the rotating shaft 31 may be inserted between two opposite groove sidewalls of the groove.

Meanwhile, the installation groove 15 can also be used for positioning the driving machine before installation, so that the driving piece 51 can be accurately installed at the preset installation position. Simultaneously, accomplish at the installation, also can play certain limiting displacement to driving piece 51 through this mounting groove 15 to be favorable to improving the stability of this driving piece 51 installation. The surrounding plate 13 may include two plate bodies disposed opposite to each other, or four plate bodies connected end to end in sequence. While the mounting socket 10 is provided with the surface of the surrounding plate 13 and the area inside the surrounding plate 13 may be formed as the bottom wall of the mounting groove 15 and partly recessed in order to better adapt the shape of the driving member 51.
