[0002] Medical devices generally include a walking base, an execution device arranged on the walking base, and a display device for human-computer interaction. In order to enable users to better use the display device, the display device is generally set to a position-adjustable structure. Current display devices generally include a display screen and a support device, and the support device is adjustable, which is used to adjust the position of the display screen to meet the user's needs for viewing the display screen more comfortably. These adjustable support devices need to be locked during the movement of the walking base and the transportation or storage of the display device, otherwise the support device may change the position of the display screen, thereby causing damage to the display screen or the support device. The current locking structure of the support device is generally arranged on the outside of the support device, and the risk of damage to the locking structure is high, and it affects the overall aesthetics of the support device. Summary of the invention

[0003] The purpose of the present application is to provide a supporting device, a display device and a surgical robot to solve the technical problem in the prior art that the locking structure is set externally and causes a high risk of damage.

[0004] To achieve the above purpose, the technical solution adopted in this application is:

[0005] In one aspect, a support device is provided, the support device comprising:

[0006] A support seat, wherein the support seat is provided with a limiting groove;

[0007] A first cantilever, the first cantilever being rotatably disposed at one end of the support seat;

[0008] A second cantilever, one end of the second cantilever being rotatably arranged at an end of the first cantilever away from the support seat, and the other end of the second cantilever being provided with a limiting rod;

[0009] A locking structure, wherein the locking structure includes a locking hook and a locking shaft, wherein the locking hook is rotationally connected to the first cantilever, the locking shaft is slidably arranged in the first cantilever, and the locking shaft can slide in a direction close to the limiting groove, the locking hook has a stowed state and an unfolded state, in the stowed state, the locking hook is disengaged from the limiting rod, and the locking shaft is disengaged from the limiting groove; in the unfolded state, the locking hook is hung on the limiting rod, and the locking shaft can be inserted into the limiting groove.

[0010] First, by setting the locking structure including the locking hook and the locking shaft, and the locking hook can be hung on the limiting rod of the second cantilever, and the locking shaft can be inserted into the limiting groove of the support seat, the locking structure can simultaneously lock the first cantilever and the second cantilever to the support seat, that is, the locking structure can simultaneously limit the rotation of the first cantilever relative to the support seat and limit the rotation of the second cantilever relative to the first cantilever. This design can simplify the locking operation of the support device and improve the convenience and efficiency of the locking operation; secondly, the locking shaft is arranged inside the first cantilever, which can not only make the connection structure between the first cantilever and the support seat more compact, but also reduce the damage risk of the locking structure and improve the aesthetics of the support device.

[0011] As an embodiment, the locking structure includes a first elastic member, which provides a force to the locking shaft toward the support seat, and a first linkage portion is provided at one end of the locking shaft close to the locking hook, and a second linkage portion is provided at one end of the locking hook connected to the first cantilever. In the stored state, the first linkage portion abuts against the second linkage portion, and the second linkage portion restricts the locking shaft to a position disengaged from the support seat; in the expanded state, the first linkage portion disengages from the second linkage portion, and the first elastic member drives the locking shaft to move in a direction close to the support seat.

[0012] By providing the first elastic member that can drive the locking shaft to be inserted into the limiting groove, and providing the first linkage part and the second linkage part that are transmission-connected, the user only needs to adjust the state of the locking hook to achieve locking and unlocking control of the locking hook and the locking shaft, thereby effectively improving the operational convenience of locking and unlocking the support device.

[0013] As an embodiment, a limiting surface is provided at one end of the support seat close to the locking structure, and the limiting groove is opened on the limiting surface; when the locking hook is in the expanded state, the locking shaft is inserted into the limiting groove, or the locking shaft abuts against the limiting surface, and when the locking shaft abuts against the limiting surface, the locking shaft will be inserted into the limiting groove within 360 degrees of rotation of the first cantilever.

[0014] On the premise of having the first elastic member, by setting the limit surface and setting the limit groove on the limit surface, the locking hook can be directly switched to the expanded state when the first cantilever is in any position, that is, no matter what position the first cantilever is in, the locking hook can be switched to the expanded state at any time, and the locking structure will not be stuck abnormally, and when the first cantilever is rotated a certain angle in the expanded state, the locking shaft will complete the action of inserting into the limit groove. Therefore, this design can save the user the operation of adjusting the first cantilever to a predetermined position before switching the state, thereby effectively improving the convenience of operation.

[0015] As an embodiment, the limiting surface is the top surface of the support seat, the locking shaft is located above the support seat, and the locking shaft is aligned with the limiting surface, and the locking shaft is slidably connected to the first cantilever along the vertical direction.

[0016] By arranging the locking shaft above the support seat and aligning it with the limiting surface, when the locking hook is in the deployed state, in addition to the downward force of the first elastic member, the locking shaft is also driven downward by its own gravity. This design of using two driving forces to drive the locking shaft downward can improve the reliability of the locking shaft being inserted into the limiting groove. This design can be well applied to the support seat with insufficient peripheral space and ample height space.

[0017] As an embodiment, the limiting surface is a side surface of the support seat, the locking shaft is located at the periphery of the support seat, and the locking shaft is aligned with the limiting surface, and the locking shaft is slidably connected to the first cantilever along a horizontal direction.

[0018] The locking shaft utilizes the force of the first elastic member toward the center direction of the support seat to insert the locking shaft into the limiting groove. This design is suitable for the support seat with insufficient height space but ample peripheral space.

[0019] As an embodiment, the locking structure includes a drive mounting frame, the drive mounting frame is arranged in the first cantilever, and the drive mounting frame is located on a side of the locking shaft away from the support seat, and one end of the first elastic member is sleeved on the drive mounting frame;

[0020] A driving groove is provided at one end of the locking shaft away from the supporting seat, and the other end of the first elastic member is inserted into the driving groove and abuts against the groove bottom of the driving groove.

[0021] By sleeved one end of the first elastic member on the drive mounting frame and inserting the other end into the drive groove, the first elastic member can be reliably fixed, and interference between the locking shaft and the drive mounting frame in the storage state can be avoided, thereby ensuring the reliability of the locking shaft being inserted into the limit groove, and facilitating the improvement of the compactness of the overall combined structure of the locking shaft, the first elastic member and the drive mounting frame, thereby reducing the difficulty of accommodating these combined structures in the first cantilever.

[0022] As an embodiment, the first cantilever is provided with a clearance hole. In the unfolded state, the locking hook passes through the clearance hole, and the clearance hole can limit the locking hook from sliding along its thickness direction.

[0023] The locking hook is restricted from sliding along its thickness direction by the clearance hole, so that the locking hook can better restrict the rotation of the second cantilever in the first plane and the second plane, that is, the locking hook can effectively restrict the rotation of the second cantilever in the horizontal plane and the vertical plane.

[0024] As an implementation manner, the width of the clearance hole is equal to the thickness of the locking hook.

[0025] By designing the width of the clearance hole to be equal to the thickness of the locking hook, the sliding of the locking hook can be more accurately limited, ensuring that the locking hook will not slide along its own thickness direction in the unfolded state, thereby enabling the locking hook to better limit the rotation of the second cantilever in the first plane and the second plane, that is, the locking hook can effectively limit the rotation of the second cantilever in the horizontal plane and the vertical plane.

[0026] As an embodiment, the locking structure includes a driving knob assembly, which is rotatably arranged on the first cantilever, one end of the driving knob assembly extends out of the first cantilever, the other end of the driving knob assembly is inserted into the first cantilever and passes through the locking hook, and the driving knob assembly is transmission-connected to the locking hook.

[0027] By providing the driving knob assembly extending outside the first cantilever, the convenience for the user to control the rotation of the locking hook can be improved.

[0028] As an embodiment, the driving knob assembly includes a central axis, and an outer knob and a positioning block fixedly arranged at both ends of the central axis, the central axis passes through the locking hook, and the central axis and the locking hook are slidingly connected along the axial direction of the central axis, and the first cantilever is provided with a positioning groove, and when the positioning block is embedded in the positioning groove, the rotation of the locking hook is restricted.

[0029] By arranging the positioning block on the locking hook and arranging the positioning groove matching the positioning block on the first cantilever, the position of the locking hook can be reliably positioned, thereby improving the reliability of locking or storage.

[0030] As an embodiment, the number of the positioning grooves is two groups, wherein the opening angle of the positioning grooves in one group corresponds to the unfolded state, and the opening angle of the positioning grooves in the other group corresponds to the stored state.

[0031] By providing two groups of positioning grooves, and the two groups of positioning grooves correspond to the storage state and the deployment state respectively, the locking hook can be reliably positioned in both the storage state and the deployment state.

[0032] As an embodiment, the driving knob assembly includes a second elastic member, one end of the second elastic member is connected to the first cantilever, the other end of the second elastic member is connected to the central axis, the outer knob or the positioning block, and the second elastic member can drive the positioning block to embed into the positioning groove.

[0033] By providing the second elastic member, the positioning block can be kept in the embedded positioning groove, thereby ensuring that the position of the locking hook is reliably fixed, thereby improving the reliability of locking or storage.

[0034] On the other hand, a display device is provided. The display device includes a display screen and the above-mentioned supporting device, wherein the display screen is mounted on the supporting device.

[0035] On the other hand, a surgical robot is provided, which includes a surgical cart, and a robotic arm and a display device arranged on the surgical cart.

[0036] The beneficial effects of the support device, display device and surgical robot provided by the present application are:

[0037] First, by setting the locking structure including the locking hook and the locking shaft, and the locking hook can be hung on the limiting rod of the second cantilever, and the locking shaft can be inserted into the limiting groove of the support seat, the locking structure can simultaneously lock the first cantilever and the second cantilever on the support seat, that is, the locking structure can simultaneously limit the rotation of the first cantilever relative to the support seat and limit the rotation of the second cantilever relative to the first cantilever. This design has a high overall structural integration and a compact structure, and can simplify the locking operation of the support device, thereby improving the convenience and efficiency of the locking operation.

[0038] Secondly, the locking shaft is arranged inside the first cantilever, which can not only make the connection structure between the first cantilever and the support seat more compact, but also reduce the damage risk of the locking structure and improve the aesthetics of the support device.

[0039] Again, by providing the first elastic member that can drive the locking shaft to be inserted into the limiting groove, and providing the first linkage part and the second linkage part that are transmission-connected, the user only needs to adjust the state of the locking hook to achieve locking and unlocking control of the locking hook and the locking shaft, thereby effectively improving the operational convenience of locking and unlocking the support device.

[0040] Finally, on the premise of having the first elastic member, by setting the limiting surface and setting the limiting groove on the limiting surface, the locking hook can be directly switched to the expanded state when the first cantilever is in any position, that is, no matter what position the first cantilever is in, the locking hook can be switched to the expanded state at any time, and the locking structure will not be stuck abnormally, and by rotating the first cantilever by a certain angle in the expanded state, the locking shaft will complete the action of inserting into the limiting groove. Therefore, this design enables the user to save the operation of adjusting the first cantilever to a predetermined position before switching the state, thereby effectively improving the convenience of operation.

[0060] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0061] This embodiment provides a supporting device, such as Figures 1 to 5 As shown, the support device includes a support seat 1, a first cantilever 2, a second cantilever 3 and a locking structure 4. The support seat 1 is provided with a limiting groove 121. The first cantilever 2 is rotatably arranged at one end of the support seat 1, and one end of the second cantilever 3 is rotatably arranged at one end of the first cantilever 2 away from the support seat 1. A limiting rod 31 is arranged at the other end of the second cantilever 3. The locking structure 4 includes a locking hook 41 and a locking shaft 42. The locking hook 41 is rotatably connected to the first cantilever 2, and the locking shaft 42 is slidably arranged in the first cantilever 2, and the locking shaft 42 can slide in a direction close to the limiting groove 121. The locking hook 41 has a storage state and an unfolded state. In the storage state, the locking hook 41 is disengaged from the limiting rod 31, and the locking shaft 42 is disengaged from the limiting groove 121; in the unfolded state, the locking hook 41 is hung on the limiting rod 31, and the locking shaft 42 can be inserted into the limiting groove 121.

[0062] First, by setting a locking structure 4 including a locking hook 41 and a locking shaft 42, and the locking hook 41 can be hung on the limiting rod 31 of the second cantilever 3, and the locking shaft 42 can be inserted into the limiting groove 121 of the support seat 1, the locking structure 4 can simultaneously lock the first cantilever 2 and the second cantilever 3 on the support seat 1, that is, the locking structure 4 can simultaneously limit the rotation of the first cantilever 2 relative to the support seat 1 and limit the rotation of the second cantilever 3 relative to the first cantilever 2. This design has a high overall structural integration and a compact structure, and can simplify the locking operation of the support device and improve the convenience and efficiency of the locking operation; secondly, the locking shaft 42 is arranged inside the first cantilever 2, which can not only make the connection structure between the first cantilever 2 and the support seat 1 more compact, but also reduce the risk of damage to the locking structure 4 and improve the aesthetics of the support device.

[0063] In the specific implementation process, Figure 1 , Figure 3 and Figure 4 As shown, the first cantilever 2 is arranged on the top of the support seat 1, and the length of the first cantilever 2 is equal to the length of the second cantilever 3. In the unfolded state, the second cantilever 3 is located above the first cantilever 2, and the second cantilever 3 is parallel to the first cantilever 2. The axis of the limit rod 31 and the rotation axis of the locking hook 41 are on the same vertical plane. This design of the same vertical plane can reduce the torsional force generated by the second cantilever 3 on the locking hook 41, which is beneficial to ensure the service life of the locking hook 41 and is conducive to the miniaturization of the locking structure 4.

[0064] In the specific implementation process, the first cantilever 2 can rotate in the first plane relative to the support base 1; the second cantilever 3 can rotate in the first plane and the second plane relative to the first cantilever 2, and the first plane is perpendicular to the second plane. Further, the first plane is a horizontal plane, and the second plane is a vertical plane.

[0065] In the specific implementation process, in the storage state, the locking hook 41 is located inside the first cantilever 2. This design can prevent the locking hook 41 from interfering with the movement of the second cantilever 3, thereby ensuring the reliability of the movement of the second cantilever 3.

[0066] In the specific implementation process, Figures 1 to 3 As shown, the first cantilever 2 is connected to the second cantilever 3 through a first composite rotating structure 5, and the first composite rotating structure 5 includes a first connecting arm 51 and a second connecting arm 52 that are rotatably connected. One end of the first connecting arm 51 away from the second connecting arm 52 is rotatably connected to the first cantilever 2, and one end of the second connecting arm 52 away from the first connecting arm 51 is rotatably connected to the second cantilever 3. The first composite rotating structure 5 enables the second cantilever 3 and the first cantilever 2 to rotate relative to each other in two directions perpendicular to each other, that is, the second cantilever 3 can rotate relative to the first cantilever 2 in first and second planes perpendicular to each other.

[0067] In the specific implementation process, Figures 1 to 3 As shown, the supporting device further includes an end bracket 6, and the end bracket 6 is used to install the display screen. The end bracket 6 is connected to the end of the second cantilever 3 away from the first cantilever 2 through a second composite rotating structure 7, and the second composite rotating structure 7 includes a third connecting arm 71 and a fourth connecting arm 72 that are rotatably connected, and the end of the third connecting arm 71 away from the fourth connecting arm 72 is rotatably connected to the second cantilever 3, and the end of the fourth connecting arm 72 away from the third connecting arm 71 is rotatably connected to the end bracket 6, and the second composite rotating structure 7 enables the end bracket 6 and the second cantilever 3 to rotate relative to each other in two directions perpendicular to each other.

[0068] In one embodiment, if Figure 4As shown, the locking structure 4 includes a first elastic member 43, which provides a force to the locking shaft 42 toward the support seat 1. A first linkage portion 421 is provided at one end of the locking shaft 42 close to the locking hook 41, and a second linkage portion 411 is provided at one end of the locking hook 41 connected to the first cantilever 2. In the retracted state, the first linkage portion 421 abuts against the second linkage portion 411, and the second linkage portion 411 limits the locking shaft 42 to a position disengaged from the support seat 1; in the unfolded state, the first linkage portion 421 disengages from the second linkage portion 411, and the first elastic member 43 drives the locking shaft 42 to move toward the direction close to the support seat 1.

[0069] By providing a first elastic member 43 that can drive the locking shaft 42 to be inserted into the limiting groove 121, and providing a first linkage part 421 and a second linkage part 411 that are transmission-connected, the user only needs to adjust the state of the locking hook 41 to achieve locking and unlocking control of the locking hook 41 and the locking shaft 42, thereby effectively improving the convenience of locking and unlocking operations of the support device.

[0070] In the specific implementation process, Figure 3 and Figure 5 As shown, the support seat 1 includes a support plate 11 and a support shaft 12, the support shaft 12 is vertically arranged, the support plate 11 is arranged at the bottom of the support shaft 12, the first cantilever 2 includes a main body arm 21 and a mounting arm 22 that are fixedly connected, the mounting arm 22 is sleeved on the periphery of the support shaft 12 and is rotatably connected to the support shaft 12, the axis of rotation of the first cantilever 2 relative to the support seat 1 is a vertical line, and the locking structure 4 is arranged on the mounting arm 22. Of course, in other embodiments, it can also be designed that: the mounting arm 22 is inserted into the support shaft 12 and is rotatably connected to the support shaft 12.

[0071] In the specific implementation process, the first elastic member 43 is a compression spring. Of course, in other embodiments, the first elastic member 43 can also be other elastic structures.

[0072] In one embodiment, if Figure 4 and Figure 5 As shown, a limiting surface 122 is provided at one end of the support seat 1 close to the locking structure 4, and a limiting groove 121 is opened on the limiting surface 122; when the locking hook 41 is in the expanded state, the locking shaft 42 is inserted into the limiting groove 121, or the locking shaft 42 abuts against the limiting surface 122, and in the state where the locking shaft 42 abuts against the limiting surface 122, the locking shaft 42 will be inserted into the limiting groove 121 within 360 degrees of rotation of the first cantilever 2.

[0073] On the premise of having the first elastic member 43, by setting the limiting surface 122 and setting the limiting groove 121 on the limiting surface 122, the locking hook 41 can be directly switched to the deployed state when the first cantilever 2 is in any position, that is, no matter what position the first cantilever 2 is in, the locking hook 41 can be switched to the deployed state at any time, and the locking structure 4 will not have any abnormal jamming. When the first cantilever 2 is rotated a certain angle in the deployed state, the locking shaft 42 will complete the insertion into the limiting groove 121. Therefore, this design enables the user to save the operation of adjusting the first cantilever 2 to a predetermined position before switching the state, thereby effectively improving the convenience of operation.

[0074] In the specific implementation process, the number of the limiting grooves 121 is one or more than two. When the number of the limiting grooves 121 is more than two, the first cantilever 2 can be locked at different positions. This design is conducive to improving the diversity of the locking postures of the support device to adapt to different application scenarios.

[0075] In one embodiment, if Figure 4 and Figure 5 As shown, the limiting surface 122 is the top surface of the support seat 1, the locking shaft 42 is located above the support seat 1, and the locking shaft 42 is aligned with the limiting surface 122, and the locking shaft 42 is slidably connected with the first cantilever 2 in the vertical direction. By setting the locking shaft 42 above the support seat 1 and aligning it with the limiting surface 122, when the locking hook 41 is in the unfolded state, in addition to the downward force of the first elastic member 43, the locking shaft 42 is also driven by its own gravity to move downward. This design of using two driving forces to drive the locking shaft 42 to move downward can improve the reliability of the locking shaft 42 being inserted into the limiting groove 121. This design can be better applied to the support seat 1 with insufficient peripheral space and ample height space.

[0076] In the specific implementation process, Figure 4 and Figure 5 As shown, the distance between the axis of the locking shaft 42 and the rotation axis of the first cantilever 2 is equal to the radius of the support shaft 12 of the support seat 1. In the stored state, during the rotation of the first cantilever 2 relative to the support seat 1, the locking shaft 42 is always located directly above the limit surface 122.

[0077] Of course, in other embodiments, it can also be designed that: the limiting surface 122 is the side of the support shaft 12 of the support seat 1, the locking shaft 42 is located at the periphery of the support seat 1, and the locking shaft 42 is aligned with the limiting surface 122, and the locking shaft 42 is slidably connected with the first cantilever 2 in the horizontal direction. In this embodiment, the locking shaft 42 uses the force of the first elastic member 43 toward the center direction of the support shaft 12 to insert the locking shaft 42 into the limiting groove 121. This design is suitable for a support seat 1 with insufficient height space and more ample peripheral space.

[0078] In one embodiment, if Figure 4 and Figure 5 As shown, the locking structure 4 includes a drive mounting frame 44, which is arranged in the first cantilever 2, and the drive mounting frame 44 is located on the side of the locking shaft 42 away from the support seat 1, and one end of the first elastic member 43 is sleeved on the drive mounting frame 44; a drive groove 422 is provided at one end of the locking shaft 42 away from the support seat 1, and the other end of the first elastic member 43 is inserted into the drive groove 422 and abuts against the bottom of the drive groove 422.

[0079] By sleeved one end of the first elastic member 43 on the drive mounting frame 44 and inserting the other end into the drive groove 422, the first elastic member 43 can be reliably fixed, and interference between the locking shaft 42 and the drive mounting frame 44 in the storage state can be avoided, thereby ensuring the reliability of the locking shaft 42 being inserted into the limit groove 121, and facilitating the improvement of the compactness of the overall combined structure of the locking shaft 42, the first elastic member 43 and the drive mounting frame 44, and reducing the difficulty of accommodating these combined structures in the first cantilever 2.

[0080] In the specific implementation process, Figure 4 As shown, the locking structure 4 also includes a shaft locking mounting frame 45, which is fixedly arranged in the first cantilever 2, and the locking shaft 42 is slidably arranged on the shaft locking mounting frame 45. The driving mounting frame 44 is arranged on a side of the shaft locking mounting frame 45 away from the support seat 1, and the first linkage portion 421 and the first elastic member 43 are both located between the driving mounting frame 44 and the shaft locking mounting frame 45.

[0081] In one embodiment, if Figure 1 As shown, the first cantilever 2 is provided with a clearance hole 23. In the unfolded state, the locking hook 41 passes through the clearance hole 23, and the clearance hole 23 can limit the sliding of the locking hook 41 along its thickness direction. The clearance hole 23 limits the sliding of the locking hook 41 along its thickness direction, so that the locking hook 41 can better limit the rotation of the second cantilever 3 in the first plane and the second plane, that is, the locking hook 41 can effectively limit the rotation of the second cantilever 3 in the horizontal plane and the vertical plane. In the specific implementation process, the clearance hole 23 is set on the mounting arm 22.

[0082] In one embodiment, the width of the clearance hole 23 is equal to the thickness of the locking hook 41. By designing the width of the clearance hole 23 to be equal to the thickness of the locking hook 41, the sliding of the locking hook 41 can be more accurately restricted, ensuring that the locking hook 41 will not slide along its own thickness direction in the unfolded state, so that the locking hook 41 can better restrict the rotation of the second cantilever 3 in the first plane and the second plane, that is, the locking hook 41 can effectively restrict the rotation of the second cantilever 3 in the horizontal plane and the vertical plane. Of course, in other embodiments, the width of the clearance hole 23 can also be designed to be greater than the thickness of the locking hook 41. Although the locking hook 41 can undergo a certain displacement in its own thickness direction in this design, the displacement is limited and the displacement is the margin allowed in the design. The movement in the thickness direction beyond the displacement is still restricted. Therefore, this design can also enable the locking hook 41 to effectively restrict the rotation of the second cantilever 3 in the horizontal plane and the vertical plane.

The locking hook 41 is inserted into the clearance gap 254, and the central axis 461 passes through the second knob bracket 252, the locking hook 41 and the first knob bracket 251 in sequence. The first knob bracket 251 is provided with a first groove 2511, and the bottom of the first groove 2511 is provided with a positioning groove 24, and the positioning block 463 is located in the first groove 2511. In the specific implementation process, the knob bracket 25 is arranged on the mounting arm 22.

[0088] In one embodiment, there are two groups of positioning grooves 24, wherein the opening angle of one group of positioning grooves 24 corresponds to the deployed state, and the opening angle of the other group of positioning grooves 24 corresponds to the stored state. By providing two groups of positioning grooves 24, and the two groups of positioning grooves 24 correspond to the stored state and the deployed state respectively, the locking hook 41 can be reliably positioned in both the stored state and the deployed state.

[0089] In a specific implementation process, the included angle of the two groups of positioning grooves 24 is equal to the included angle of the locking hook 41 in the stored state and in the deployed state.

[0090] In one embodiment, if Figure 6 and Figure 7 As shown, the driving knob assembly 46 includes a second elastic member 464, one end of the second elastic member 464 is connected to the first cantilever 2, and the other end of the second elastic member 464 is connected to the center axis 461, the outer knob 462 or the positioning block 463, and the second elastic member 464 can drive the positioning block 463 to embed into the positioning groove 24.

[0091] By providing the second elastic member 464 , the positioning block 463 can be kept in the embedded positioning groove 24 , thereby ensuring that the position of the locking hook 41 is reliably fixed, thereby improving the reliability of locking or storage.
