Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of locking, and particularly relates to a locking mechanism and a locking system. BACKGROUND

[0002] In an industrial production line, a locking mechanism is needed to install a screw or other locking part into a threaded hole of a product. However, in the process of installing the locking part, the locking mechanism usually needs to use a cylinder or other driving part to separately drive the locking part to gradually extend into the threaded hole. The wall of the threaded hole also exerts a force on the locking part, so that the locking part is easily reversely pressed against the locking mechanism, resulting in that the locking mechanism is greatly pressed, the components of the locking mechanism are damaged, and the locking process of the locking part is affected. SUMMARY

[0003] The embodiments of the application aim to provide a locking mechanism and a locking system, which can solve the problem that the locking mechanism is easily damaged by pressure in the related art.

[0004] In a first aspect, the embodiments of the application provide a locking mechanism, which comprises a supporting part, a locking part and an elastic part. The locking part is slidably arranged in the supporting part along a first direction. The locking part is used to connect a locking part to be locked. The elastic part is connected to the locking part.

[0005] When the supporting part drives the locking part to move along the first direction, the locking part can lock the locking part to be locked. The locking part to be locked exerts a force on the locking part, so that the locking part moves in the opposite direction of the first direction relative to the supporting part, and the elastic part is elastically deformed.

[0006] In a second aspect, the embodiments of the application also provide a locking system, which comprises a robot and the above-mentioned locking mechanism. The robot is connected to the supporting part. The robot can drive the locking mechanism to move along the first direction.

[0007] In the embodiments of the application, the locking mechanism is provided in a sliding form, and the elastic part is additionally provided. During the process that the supporting part drives the locking part to move along the first direction, the locking part to be locked gradually extends into the threaded hole. The wall of the threaded hole exerts a force on the locking part to be locked, so that the locking part to be locked reversely presses the locking part. Therefore, the locking part moves in the opposite direction of the first direction relative to the supporting part, and the elastic part is elastically deformed. The elastic force of the elastic part acts on the locking part to be locked. The elastic performance of the elastic part is used to buffer the locking part, so as to avoid that the locking part is damaged due to too large instantaneous pressure. Moreover, the elastic force of the elastic part can also drive the locking part to reversely reset, so that the locking part continues the next round of locking process.

[0033] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0034] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a category and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0035] The locking mechanism and the locking system provided by the embodiments of the present application will be described in detail below in combination with the drawings and specific embodiments and their application scenarios.

[0036] Please refer to Figures 1-8 The locking mechanism 10 disclosed in the embodiments of the present application includes a support 100, a fastening component 200, and an elastic member 300, wherein the support 100 can be a support plate, the support 100 serves as a mounting base for the fastening component 200 and the elastic member 300, and the robot 20 can drive the locking mechanism 10 to move through the support 100; the fastening component 200 is used to connect a to-be-fastened member S to fasten the to-be-fastened member S, and the to-be-fastened member S can be but is not limited to a screw.

[0037] The locking component 200 is slidably disposed on the support member 100 along the first direction A. Optionally, the locking mechanism 10 further includes a guide rail 110 and a slider. The guide rail 110 extends along the first direction A, and the support member 100 is provided with the guide rail 110. The locking component 200 is connected to the slider, and the guide rail 110 and the slider are slidably engaged, so that the locking component 200 can slide relative to the support member 100; or, the locking component 200 can also be slidably connected to the support member 100 through other structures. In this embodiment, the first direction A is parallel to the extension direction of the locking component 200.

[0038] The elastic element 300 is connected to the locking component 200. Optionally, the elastic element 300 can be, but is not limited to, a spring. The first end of the elastic element 300 is a fixed end, and its position remains unchanged. The second end of the elastic element 300 can directly abut against the locking component 200. Alternatively, the second end of the elastic element 300 and the locking component 200 can be connected by welding, bonding, or other methods. In short, when the locking component 200 slides relative to the support member 100 due to the counter-drive of the locking component S, the second end of the elastic element 300 moves relative to the first end of the elastic element 300, and the elastic element 300 generates elastic deformation and accumulates elastic potential energy.

[0039] When the support member 100 drives the locking member 200 to move along the first direction A, the locking member 200 can lock the member to be locked, the member to be locked S applies a force to the locking member 200, causing the locking member 200 to move relative to the support member 100 in the opposite direction of the first direction A, and the elastic member 300 undergoes elastic deformation, accumulating elastic potential energy. Specifically, during the process of the robot 20 driving the support member 100 to move along the first direction A, refer to Figure 3 As shown, the locking component 200 drives the component S to be locked to the locking area S1. During the locking process, specifically during the locking of the screw, the wall of the threaded hole in the locking area S1 will apply a force opposite to the first direction A to the component S to be locked. Then, the component S to be locked will also apply a force opposite to the first direction A to the locking component 200. The locking component 200 will slide relative to the support 100 in the opposite direction of the first direction A, thereby causing the elastic component 300 to undergo elastic deformation.

[0040] Similarly, after the locking component 200 has finished locking, the locking mechanism 10 is driven by the robot 20 to move in the opposite direction of the first direction A. The locking component S is separated from the locking component 200. Then, the locking component 200 loses the force exerted on it by the locking component S. At this time, the elastic element 300 releases its elastic potential energy and restores its elastic deformation. The elastic element 300 drives the locking component 200 to slide relative to the support member 100 along the first direction A so that the locking component 200 is reset.

[0041] In this embodiment, the locking mechanism 10 configures the locking component 200 in a sliding manner and adds an elastic element 300. During the movement of the locking component 200 along the first direction A driven by the support member 100, the component S to be locked applies reverse pressure to the locking component 200. Therefore, the locking component 200 moves relative to the support member 100 in the opposite direction of the first direction A, causing the elastic element 300 to undergo elastic deformation. The elastic force of the elastic element 300 acts on the component S to be locked, and the elastic properties of the elastic element 300 buffer the locking component 200, preventing it from being damaged by excessive instantaneous pressure. Furthermore, the elastic force of the elastic element 300 can also drive the locking component 200 to reset in the reverse direction, facilitating the continued locking process of the locking component 200.

[0042] In this application, the locking mechanism 10 further includes a guide post 400, which is connected to the support member 100. The guide post 400 extends along a first direction A, and the elastic member 300 is sleeved on the outside of the guide post 400. Optionally, the support member 100 is provided with a transition portion that protrudes from the surface of the support member 100. The end of the guide post 400 can be connected to the transition portion by welding, bonding, or other means to fix the guide post 400 relative to the support member 100.

[0043] This configuration, using the guide post 400 to guide the deformation direction of the elastic element 300, helps the elastic element 300 to accurately generate elastic deformation along the first direction A, avoids the deformation direction of the elastic element 300 from deviating, and also helps the elastic element 300 to accurately restore the direction of elastic deformation in the future, so as to accurately drive the locking component 200 to reset.

[0044] In a further embodiment, reference is made to... Figure 2 As shown, the number of elastic elements 300 is at least two, and the locking mechanism 10 also includes at least two guide posts 400. Each guide post 400 is connected to the support member 100, and each guide post 400 extends along the first direction A. The two guide posts 400 are located on opposite sides of the locking member 200, and each guide post 400 has at least one elastic element 300 on its exterior.

[0045] Optionally, the support member 100 is a support plate, and there are two guide posts 400. Along the second direction, the two guide posts 400 are located on opposite sides of the locking member 200. The second direction is perpendicular to the first direction A, and the first direction A and the second direction are parallel to the plane where the support plate is located. Each guide post 400 may be provided with an elastic element 300 on its exterior, or two elastic elements 300 may be provided on the exterior of each guide post 400. These two elastic elements 300 act on the locking body 210 and the adsorption member 230 mentioned later, respectively.

[0046] In this way, the number of elastic members 300 is increased, which is conducive to increasing the elastic force in the locking process, and in turn is conducive to timely resetting of the locking component 200. In addition, the number of guide columns 400 is increased, and each guide column 400 exerts guidance on different elastic members 300 from different positions, which is conducive to accurate elastic deformation of each elastic member 300 in the first direction A, and avoids deviation of the deformation direction of the elastic member 300.

[0047] Optionally, as shown in Figure 1 The locking mechanism 10 further includes a clamping ring 410 connected with the guide column 400, and the first end of the elastic member 300 directly abuts against the clamping ring 410, so that the first end of the elastic member 300 is a fixed end. The clamping ring 410 corresponds to the guide column 400 in a one-to-one manner. Further optionally, the clamping ring 410 and the guide column 400 can be fixedly connected by welding, bonding or the like.

[0048] Of course, in other embodiments, the locking mechanism 10 can not be provided with the guide column 400, or the number of guide columns 400 is one.

[0049] In the scheme of the present application, as shown in Figure 1 and Figure 2 The locking component 200 includes a locking body 210 and a rotating locking rod 220.

The housing of the electric wrench is the locking body 210, and the rotating rod of the electric wrench can be the rotating locking rod 220. The electric wrench can control the torque and rotation angle of the to-be-locked member S, and the locking effect can be identified through these two parameters.

[0050] The first end of the rotating locking rod 220 extends into the locking body 210, and the two can be rotatably connected through a rotating shaft, or the two can be rotatably connected through a ball. Specifically, the inner wall of the locking body 210 and the surface of the rotating locking rod are provided with annular grooves. Part of the ball extends into the annular groove of the locking body 210, and the other part of the ball extends into the annular groove of the rotating locking rod, so as to realize rotation of the rotating locking rod relative to the locking body 210.

[0051] The locking main body 210 is in sliding connection with the support 100 along the first direction A. Optionally, the sliding block in the above includes a first sliding block 511, the locking main body 210 is connected with the first sliding block 511, the first sliding block 511 is in sliding cooperation with the guide rail 110, further optionally, the locking mechanism 10 further includes a locking mounting plate 510, the locking main body 210 is arranged on the locking mounting plate 510, and the locking mounting plate 510 is connected with the first sliding block 511. Wherein, the locking main body 210 and the locking mounting plate 510, the locking mounting plate 510 and the first sliding block 511 can be fixedly connected through welding, bonding, bolt connection and the like.

[0052] In a further embodiment, the locking component 200 further includes a suction accessory 230, the rotating locking rod 220 is used to suck the to-be-locked member S through the suction accessory 230, and the suction accessory 230 is in sliding connection with the support 100 along the first direction A. Optionally, the sliding block in the above further includes a second sliding block 521, the suction accessory 230 is connected with the second sliding block 521, the second sliding block 521 is in sliding cooperation with the guide rail 110, further optionally, the locking mechanism 10 further includes a suction mounting plate 520, the suction accessory 230 is arranged on the suction mounting plate 520, and the suction mounting plate 520 is connected with the second sliding block 521. The suction accessory 230 and the suction mounting plate 520, the suction mounting plate 520 and the second sliding block 521 can be fixedly connected through welding, bonding, bolt connection and the like.

[0053] The number of the elastic members 300 is at least two, wherein the two elastic members 300 respectively act on the locking main body 210 and the suction accessory 230. Optionally, the number of the guide columns 400 is two, the two guide columns 400 are respectively located on the two opposite sides of the locking component 200, each guide column 400 penetrates through the suction mounting plate 520 and the locking mounting plate 510 respectively, and the outside of each guide column 400 is sleeved with two elastic members 300, the two elastic members 300 respectively act on the locking main body 210 and the suction accessory 230, further optionally, the two elastic members 300 on the same guide column 400 respectively act on the locking mounting plate 510 and the suction mounting plate 520.

[0054] Reference Figure 4 and Figure 5As shown, the suction accessory 230 is provided with a suction cavity 231, and the second end of the rotating locking rod 220 extends into the suction cavity 231. The suction accessory 230 sucks the to-be-locked part S through the suction cavity 231. The suction accessory 230 is provided with the suction cavity 231 and a slot 232 in communication. When the to-be-locked part S extends into the slot 232, the rotating locking rod 220 is in contact with the to-be-locked part S. Optionally, the suction cavity 231 and the suction accessory 230 extend along the second direction. The locking mechanism 10 further comprises a connector 240. An outlet end of the connector 240 is in communication with the suction cavity 231, and an inlet end of the connector 240 is used to connect a vacuum generator. In this way, the vacuum generator generates negative pressure in the suction cavity 231 through the connector 240, so that the suction cavity 231 sucks the to-be-locked part S through the slot 232, and the to-be-locked part S is in a state of continuously extending into the slot 232, ensuring that the rotating locking rod 220 is in continuous contact with the to-be-locked part S, and realizing the connection between the rotating locking rod 220 and the to-be-locked part S.

[0055] Further optionally, as shown in Figure 6 and Figure 7 As shown, a plurality of suction holes 233 are arranged at intervals along the circumference of the rotating locking rod 220. The suction cavity 231 is in communication with the slot 232 through the suction holes 233. The suction holes 233 are uniformly distributed or non-uniformly distributed along the circumference of the rotating locking rod 220. When the rotating locking rod 220 extends into the suction cavity 231, in order to ensure the coaxiality of the rotating locking rod 220 and the suction accessory 230, the gap between the rotating locking rod 220 and the suction cavity 231 is small. When the rotating locking rod 220 is occasionally skewed, the gap is blocked, which is not sufficient for the negative pressure gas to pass through to suck the to-be-locked part S. Therefore, by providing the suction holes 233, the slot 232 is in smooth communication with the suction cavity 231 through the suction holes 233, and the suction accessory 230 smoothly sucks the to-be-locked part S.

Further, the at least two elastic members 300 are respectively connected to the suction accessory 230 and the locking main body 210, that is, different parts of the locking part 200 are respectively connected to different elastic members 300, which is conducive to increasing the elastic force in the locking process and driving the overall locking part 200 to reset in time.

By adopting the embodiment, the sealing fixing member 600 is in threaded connection with the adsorption mounting plate 520, which improves the connection tightness of the sealing fixing member 600 and the adsorption mounting plate 520. Since the adsorption mounting plate 520 supports the adsorption member 230, it is beneficial to tightly seal the adsorption cavity 231 by the sealing fixing member 600 and improve the sealing performance.

When the first fixing member 610 or the second fixing member 620 needs to be detached, the connecting member can be loosened to be separated from the third threaded hole 612.

[0072] In the scheme of the present application, referring to Figure 1 and Figure 2As shown, the locking mechanism 10 further comprises a clamping member 720 and a clamping driving member 710. The clamping driving member 710 is arranged on the support member 100. The driving end of the clamping driving member 710 is connected with the clamping member 720. The clamping driving member 710 can drive the clamping member 720 to clamp the to-be-locked member S connected with the locking component 200. When the locking component 200 is connected with the to-be-locked member S, the clamping driving member 710 drives the clamping member 720 to clamp the to-be-locked member S. Optionally, the number of the clamping member 720 is two. The clamping driving member 710 is provided with two driving ends. The driving ends are connected with the clamping members 720 one by one. The clamping driving member 710 can drive the two clamping members 720 to be close to each other to clamp the to-be-locked member S. The clamping driving member 710 can also drive the two clamping members 720 to be away from each other to release the to-be-locked member S.

[0073] Optionally, the locking mechanism 10 further comprises a clamping support member 700. The clamping support member 700 provides a mounting basis for the clamping driving member 710. The clamping support member 700 is connected with the support member 100. The clamping driving member 710 is arranged on the clamping support member 700. The clamping support member 700 and the support member 100 and the shell of the clamping driving member 710 can be fixedly connected through welding, bonding or the like.

[0074] In the embodiment, after the locking component 200 is connected with the to-be-locked member S, the clamping member 720 is used to clamp the to-be-locked member S, so as to fix the to-be-locked member S relative to the locking component 200. This avoids the to-be-locked member S from moving during the transfer and the locking process, so as to avoid the position of the to-be-locked member S from being deviated. This is beneficial to improving the locking accuracy. Moreover, if the position of the to-be-locked member S relative to the locking component 200 is deviated, the clamping member 720 is used to clamp the to-be-locked member S, so as to correct the position of the to-be-locked member S, thereby ensuring the locking accuracy.

[0075] Of course, in other embodiments, the locking mechanism 10 can not be provided with the clamping member 720 and the clamping driving member 710. In the locking process, only the locking component 200 is used to connect the to-be-locked member S.

[0076] In the scheme of the present application, reference is made to Figure 1 and Figure 2As shown, the locking mechanism 10 further comprises an inductive sheet 810 and a photoelectric sensor 820, one of the inductive sheet 810 and the photoelectric sensor 820 is arranged on the locking component 200, and the other of the inductive sheet 810 and the photoelectric sensor 820 is arranged on the support 100. Specifically, the inductive sheet 810 can be arranged on the locking component 200, and the photoelectric sensor 820 can be arranged on the support 100, or the inductive sheet 810 can be arranged on the support 100, and the photoelectric sensor 820 can be arranged on the locking component 200. Optionally, the inductive sheet 810 is connected to the locking mounting plate 510 by welding, bonding or the like, and the photoelectric sensor 820 is connected to the support 100 by welding, bonding or the like.

[0077] When the inductive sheet 810 and the photoelectric sensor 820 are relatively moved to the preset relative position, the position of the support 100 is fixed, the positions of the locking component 200 and the to-be-locked piece S are fixed, and the locking component 200 stops the locking process. When the inductive sheet 810 and the photoelectric sensor 820 are not relatively moved to the preset relative position, the support 100 continues to drive the locking component 200 and the to-be-locked piece S to move, so as to lock the to-be-locked piece S to the locking area S1.

[0078] Specifically, the photoelectric sensor 820 comprises opposite photoelectric emitters and photoelectric receivers. When the inductive sheet 810 does not extend between the photoelectric emitters and the photoelectric receivers, the photoelectric signal emitted by the photoelectric emitters can be received by the photoelectric receivers. When the inductive sheet 810 extends between the photoelectric emitters and the photoelectric receivers, the inductive sheet 810 blocks the photoelectric signal, and the photoelectric receivers cannot receive the photoelectric signal. When the inductive sheet 810 and the photoelectric sensor 820 are relatively moved to the preset relative position, the inductive sheet 810 extends between the photoelectric emitters and the photoelectric receivers, which indicates that the locking component 200 moves a large distance in the opposite direction of the first direction A relative to the support 100, and the locking component 200 does not correctly perform the locking. At this time, an abnormal situation occurs, so the position of the support 100 is fixed, and the locking process is stopped.

[0079] In this way, the relative position of the locking component 200 and the support plate is sensed by using the inductive sheet 810 and the photoelectric sensor 820, and whether the to-be-locked piece S is successfully locked is detected, so that the position of the support 100 is fixed and the locking process is stopped in time when the locking is abnormal, and the components of the locking area S1 are prevented from being damaged by the continuous abnormal locking of the to-be-locked piece S.

[0080] In the embodiment, the locking area S1 can be an area of the circuit board, the circuit board is provided with a screw hole, the to-be-locked member S is a long screw, and the long screw needs to be locked into the screw hole. When the long screw abuts against the edge of the screw hole, that is, the long screw does not successfully extend into the screw hole, it indicates that the locking is abnormal. During the movement of the support member 100 along the first direction A, the circuit board applies a force to the locking member 200 through the long screw, so that the position of the long screw and the locking member 200 is fixed, the locking member 200 continues to slide relative to the support member 100 along the reverse direction of the first direction A, and then the inductive sheet 810 moves relative to the photoelectric sensor 820. The inductive sheet 810 extends between the photoelectric emitter and the photoelectric receiver until the photoelectric emitter and the photoelectric receiver are in a preset relative position. The position of the support member 100 is fixed, and the circuit board is prevented from being damaged.

[0081] In addition, the end of the locking rod 220 extends into the nut of the long screw, avoiding the need to clamp the locking rod 220 on the nut of the long screw, and being beneficial to improving the qualified rate of locking the long screw.

[0082] In the scheme of the application, referring to Figure 1 and Figure 2 The locking mechanism 10 further includes a camera 910 and a light source 920. The camera 910 is provided with a lens 911, and the light source 920 is used to illuminate the shooting environment of the lens 911. Optionally, the camera 910 and the light source 920 are located on one side of the locking member 200, and the locking mechanism 10 further includes a camera support member 900. The camera 910 is arranged on the camera support member 900, the camera support member 900 is connected with the support member 100, and the camera 910 and the camera support member 900 and the camera support member 900 and the support member 100 can be fixedly connected by welding, bonding or the like.

[0083] In this way, the locking mechanism 10 is additionally provided with the camera 910, and the camera 910 is used for shooting to identify the locking area S1, accurately determine the position of the to-be-locked member S, and save the problem of slow locking process and inaccurate locking caused by relying on human eye vision positioning during manual operation.

[0084] Of course, in other embodiments, the locking mechanism 10 can not be provided with the camera 910 and the light source 920.

[0085] In the related art, after the locking component 200 is connected to the to-be-locked part S, the rotating locking rod 220 is spaced apart from the to-be-locked part S in the first direction A, that is, the rotating locking rod 220 is separated from the to-be-locked part S, so that a linear driving member such as a pneumatic cylinder or an electric cylinder is needed to drive the rotating locking rod 220 to move a certain distance, so that the rotating locking rod 220 is in contact with the to-be-locked part S, and then the rotating locking rod 220 drives the to-be-locked part S to rotate to realize the locking process. However, in this way, the action of the linear driving member increases the time length of the locking process, and reduces the locking efficiency. In the present case, the elastic member 300 is added, and the locking component 200 can be buffered, so that after the locking component 200 is connected to the to-be-locked part S, the rotating locking rod 220 can be directly in contact with the to-be-locked part S, avoiding the problem that the linear driving member and the to-be-locked part S are directly in hard contact in the initial state and need to be separated, so that the linear driving member does not need to be driven to move, the locking time length is saved, and the locking efficiency is improved.

[0086] Based on the locking mechanism 10 disclosed in the present application, the present embodiment further discloses a locking system, as shown in Figure 8 , the locking system comprises a robot 20 and the above-mentioned locking mechanism 10, the robot 20 is connected to the support 100, and the robot 20 can drive the locking mechanism 10 to move along the first direction A. Optionally, the robot 20 can be an industrial robot, the robot 20 is connected to the support 100, and the two can be connected by welding, bonding or the like, and the robot 20 drives the locking component 200 and the to-be-locked part S to move along the first direction A through the support 100.

[0087] By using the present embodiment, the locking component 200 of the locking system is in a slidable manner, and the elastic member 300 is added, so that in the process of moving the locking component 200 along the first direction A by the support 100, the to-be-locked part S applies pressure to the locking component 200 in the opposite direction, so that the locking component 200 moves in the opposite direction along the first direction A relative to the support 100, and then the elastic member 300 is elastically deformed, the elastic force of the elastic member 300 acts on the to-be-locked part S, and the locking component 200 is buffered by relying on the elastic performance of the elastic member 300, so as to avoid damage caused by excessive instantaneous pressure on the locking component 200.

[0088] Optionally, as shown in Figure 8 , the locking system further comprises a workbench 30, a conveyor 40 and a feeder 50, the conveyor 40, the feeder 50 and the locking mechanism 10 are all arranged on the workbench 30, the conveyor 40 can adopt a conveying belt, and is specifically used for conveying the locking area S1 of a product to a position where the robot 20 can transfer the product, and the feeder 50 is used for providing the to-be-locked part S. The robot 20 drives the locking mechanism 10 to move to the feeder 50 to adsorb the to-be-locked part S, and then the robot 20 drives the locking mechanism 10 to move the to-be-locked part S to the locking area S1 for operation.

[0089] In an optional embodiment, the robot 20 is in communication connection with the photoelectric sensor 820, and optionally, the robot 20 is in communication connection with the photoelectric receiver, and the robot 20 acts according to the receiving information of the photoelectric receiver, specifically, in the case that the photoelectric receiver receives the photoelectric signal, it indicates that the sensing sheet 810 and the photoelectric sensor 820 do not move to the preset relative position, and the robot 20 continues to transfer the locking mechanism 10, and the support 100 continues to move along the first direction A; in the case that the photoelectric receiver does not receive the photoelectric signal, it indicates that the sensing sheet 810 and the photoelectric sensor 820 move to the preset relative position, and the robot 20 stops transferring the locking mechanism 10, and the position of the support 100 is fixed.
