Description

Technical Field

[0001] This application relates to the technical field of electrical equipment, and particularly relates to a positioning component and a spring feeding mechanism. Background Art

[0002] The assembly of a circuit breaker is a precise process, which involves the correct assembly and adjustment of multiple modules. The tripping module is one of the more important modules in the circuit breaker. To ensure the reliability of the circuit breaker during use, the correct assembly of the tripping module is particularly important.

[0003] Generally, when assembling the tripping module, a spring needs to be installed into the tripping module. Moreover, when installing the spring into the tripping module, it is generally necessary to operate through a spring feeding mechanism. However, in the prior art, when installing the spring into the tripping module through the spring feeding mechanism, it is often impossible to control the number of turns of the spring caught in the tripping module, which affects the reliability of the circuit breaker during use. Utility Model Content

[0004] This application provides a positioning component and a spring feeding mechanism to control the initial state of the spring during installation.

[0005] In a first aspect, this application provides a positioning component applied to a spring feeding mechanism. The spring feeding mechanism includes a spring. The positioning component includes: a positioning block, a limiting stop block, and a positioning assembly. The positioning block is provided with a positioning groove and a first installation groove, and the first installation groove communicates with the positioning groove. The limiting stop block is arranged on one side of the positioning block. A positioning protrusion is provided on the side of the limiting stop block facing the positioning groove, and the positioning protrusion is located on the rotation path of the end of the spring close to the limiting stop block. The positioning assembly includes a slider, and the slider is movably arranged in the first installation groove. The slider can drive the spring located in the positioning groove to rotate, so that the end of the spring close to the limiting stop block is limited by the positioning protrusion.

[0006] Through the above solution, the positioning component provided in this application sets a positioning protrusion on the limiting stop block, sets a first installation groove on the positioning block, and sets a movable slider in the first installation groove. When the slider moves along the first installation groove, the slider can drive the spring to rotate until the end of the spring close to the limiting stop block abuts against the positioning protrusion. At this time, the spring is limited, and the spring is in the correct installation state. In this way, when the spring is installed in the tripping module, two turns can be caught in the installation groove of the tripping module, thereby reducing the fluctuation range of the tripping force value of the circuit breaker and improving the reliability of the circuit breaker during use.

[0007] In a possible design, the side wall of the slider is in sliding contact with the groove wall of the first installation groove.

[0008] Through the above solution, the groove wall of the first installation groove can limit the slider. When the side wall of the slider is in sliding contact with the groove wall of the first installation groove, the probability of the slider shaking in the first installation groove can be reduced, thereby improving the stability of the slider when moving out of the first installation groove. In this way, when the slider drives the spring to rotate, the rotation process of the spring is more stable.

[0009] In a possible design, at least one protrusion is provided on the side of the slider facing the positioning groove. The protrusion abuts against the spring.

[0010] Through the above solution, by providing a protrusion on the side of the slider facing the positioning groove, the roughness of the side wall of the slider facing the positioning groove can be increased, thereby increasing the friction between the slider and the spring. When the protrusion abuts against the spring, the friction between the protrusion and the spring can be used to drive the spring to rotate when the slider moves along the first installation groove.

[0011] In a possible design, a relief groove is provided on the side of the first installation groove facing the positioning groove. The protrusion is located in the relief groove.

[0012] Through the above solution, since the protrusion is provided on the side wall of the slider and the slider is in sliding contact with the groove wall of the first installation groove, a relief groove that can accommodate the protrusion is provided in the first installation groove. In this way, the probability of interference between the groove wall of the first installation groove and the protrusion when the slider moves along the first installation groove can be reduced. The probability of the problem that the slider is stuck in the first installation groove and cannot move due to the interference between the groove wall of the first installation groove and the protrusion is reduced, and the reliability of the slider in use is increased.

[0013] In a possible design, the positioning assembly includes a friction block. The slider is provided with a second installation groove, and the second installation groove communicates with the positioning groove. The friction block is arranged in the second installation groove, and the side of the friction block facing the positioning groove protrudes from the slider, and the side of the friction block facing the positioning groove abuts against the spring.

[0014] Through the above solution, by providing a second installation groove on the slider and arranging a friction block in the second installation groove, the slider can drive the spring to rotate through the friction between the friction block and the spring. Moreover, setting the friction block can reduce the probability of direct contact between the slider and the spring, improve the service life of the slider, and thus also reduce the later maintenance cost of the positioning assembly.

[0015] In a possible design, a relief groove is provided on the side of the first installation groove facing the positioning groove. The part of the friction block protruding from the slider is located in the relief groove.

[0016] Through the above solution, the slider is in sliding contact with the groove wall of the first installation groove, and the friction block protrudes from the side wall of the slider. A relief groove capable of accommodating the friction block can be provided in the first installation groove. In this way, the probability of interference between the groove wall of the first installation groove and the friction block when the slider moves along the first installation groove can be reduced. The probability of the problem that the slider is stuck in the first installation groove and cannot move due to the interference between the groove wall of the first installation groove and the friction block is reduced, and the reliability of the slider in use is increased.

[0017] In a possible design, the positioning protrusion includes a guiding surface and a stopping surface. The guiding surface and the stopping surface are adjacent in position. The guiding surface can guide one end of the spring close to the limit stop, and the stopping surface can limit one end of the spring close to the limit stop.

[0018] Through the above solution, the setting of the guiding surface not only does not block one end of the spring close to the limit stop when the spring rotates, but also can guide one end of the spring close to the limit stop. In this way, the difficulty of the spring rotating in the positioning groove can be reduced. And the setting of the stopping surface can limit one end of the spring close to the limit stop, thereby limiting the rotation of the spring. When one end of the spring close to the limit stop is limited by the stopping surface, the initial installation position of the spring is corrected.

[0019] In a possible design, the positioning assembly further includes a driving member, and the driving shaft of the driving member is connected to the slider.

[0020] Through the above solution, the setting of the driving member can reduce the labor cost required for correcting the initial installation position of the spring. Moreover, the opening or closing of the driving member can be controlled by a controller, so that the operation process of the slider can be more accurate, the reliability of the slider in use is improved, and further the reliability of the positioning assembly in use is improved.

[0021] In a possible design, the driving member is a cylinder or a hydraulic cylinder, and the driving shaft is a piston rod.

[0022] Through the above solution, the cylinder and the hydraulic cylinder have the advantages of stable power output, fast action speed, high safety, etc. Selecting a cylinder or a hydraulic cylinder to drive the slider to move in the first installation groove can improve the reliability of the slider in the use process, and further improve the reliability of the positioning assembly in use.

[0023] In a second aspect, the present application provides a spring feeding mechanism, including a linear vibrator, a spring, a gripper, and the positioning assembly mentioned in the first aspect above. The linear vibrator is arranged on one side of the positioning assembly, and the discharge port of the linear vibrator is communicated with the positioning groove of the positioning assembly. The spring is located in the linear vibrator, and the spring can enter the positioning groove through the discharge port under the transportation of the linear vibrator. The gripper is located on one side of the positioning groove, and the gripper can grab the spring from the positioning groove.

[0024] With the above solution, the spring feeding mechanism mentioned in the present application can use a linear vibrator to convey the spring into the positioning component, and then the spring is grasped and installed into the tripping module by a gripper. Through the automated procedure, the installation difficulty of the spring is reduced, and the labor cost during the assembly of the circuit breaker is saved. More importantly, the positioning component mentioned in the present application can correct the initial state of the spring, so that after the spring is installed in the tripping module, the reliability of the tripping module can be increased, thereby increasing the reliability of the circuit breaker. Therefore, using the spring feeding mechanism including the positioning component mentioned in the present application can also increase the reliability of the circuit breaker.

[0025] For the spring feeding mechanism provided in the second aspect above, the beneficial effects can refer to the beneficial effects brought by the first aspect and each possible implementation manner of the first aspect, which will not be elaborated here. Description of the Drawings

[0046] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0054] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the drawings.

[0055] A circuit breaker is an electrical protection device that can close and carry current under normal operating conditions, and quickly disconnect the circuit under abnormal conditions, such as overload or short circuit, to protect the safe operation of the electrical system. The tripping module is a key component in the circuit breaker, responsible for automatically cutting off the current when abnormal conditions such as overload or short circuit occur in the circuit.

[0056] A spring is usually provided in the trip module. The main functions of the spring in the trip module are to provide power and maintain the tension of the mechanical structure. Under normal operating conditions, the spring is usually compressed or stretched to store energy. When a circuit fault occurs, the mechanism inside the trip module is triggered, causing the spring to release energy and quickly push the trip module to act, thereby forcing the contacts of the circuit breaker to separate.

[0057] However, in the prior art, when the spring is snapped into the installation groove of the trip module, the situation where the number of turns of the spring snapped in is insufficient often occurs. For example, one turn of the spring is snapped into the installation groove of the trip module, or one and a half turns of the spring are snapped into the installation groove of the trip module, and the other half turn of the spring is stuck on the edge of the installation groove. When the above problems occur, it will cause the trip force value of the circuit breaker to fluctuate too much, thus affecting the stability of the circuit breaker trip.

[0058] Therefore, the present application provides a spring feeding mechanism to solve the problem of insufficient number of turns snapped into the installation groove of the spring trip module.

[0059] Figure 1 It is a schematic diagram of the overall structure of the spring feeding mechanism provided by the embodiment of the present application. Figure 2 It is a schematic diagram of the structure of the positioning block provided by the embodiment of the present application. Figure 3 It is a schematic diagram of the slider in the initial state provided by the embodiment of the present application. The initial state of the slider can be the position when the slider has not moved out of the positioning block. As Figures 1 to 3 shown, the present application provides a spring feeding mechanism, including a linear vibrator 600, a spring 700, a gripper 800 and a positioning assembly. The linear vibrator 600 is arranged on one side of the positioning assembly, and the discharge port of the linear vibrator 600 communicates with the positioning groove 110 of the positioning assembly. The spring 700 is located inside the linear vibrator 600, and the spring 700 can enter the positioning groove 110 through the discharge port under the conveyance of the linear vibrator 600. The gripper 800 is located on one side of the positioning groove 110, and the gripper 800 can grasp the spring 700 from the positioning groove 110.

[0060] The linear vibrator 600 can convey the spring 700 by vibration. A channel is provided inside the linear vibrator 600, with the two ends being the feed port and the discharge port respectively. The spring 700 can enter the channel inside the linear vibrator 600 from the feed port of the linear vibrator 600, and then enter the positioning groove 110 of the positioning assembly through the discharge port. The diameter of the channel inside the linear vibrator 600 can be the same as the diameter of the spring 700, or the diameter of the channel inside the linear vibrator 600 can be slightly larger than the diameter of the spring 700 to limit the spring 700 while accommodating and conveying it. When the linear vibrator 600 conveys the spring 700, multiple springs 700 can be arranged in a straight line inside the channel of the linear vibrator 600.

[0061] The positioning component further includes a proximity detector, which can be connected to an external controller. The proximity detector can detect the position of the spring 700 in the positioning groove 110. After the proximity detector detects that the spring 700 is approaching, the proximity detector sends a signal to the external controller, and the positioning component corrects the initial installation position of the spring 700. Then, the external controller controls the gripper 800 to grip the spring 700. Next, when the spring 700 is in the correct installation position, the spring 700 is installed into the tripping module.

[0062] In summary, the spring feeding mechanism mentioned in the present application can use the linear vibrator 600 to convey the spring 700 into the positioning component, and then the gripper 800 grabs and installs the spring 700 into the tripping module. Through an automated program, the installation difficulty of the spring 700 is reduced, and the labor cost during the assembly of the circuit breaker is saved. More importantly, the positioning component mentioned in the present application can correct the initial state of the spring 700. In this way, after the spring 700 is installed in the tripping module, the reliability of the tripping module can be increased, thereby increasing the reliability of the circuit breaker. Therefore, using the spring feeding mechanism including the positioning component mentioned in the present application can also increase the reliability of the circuit breaker.

[0063] The positioning component mentioned in the present application will be specifically described below with reference to the accompanying drawings.

[0064] Figure 4 It is a schematic diagram of the slider moving along the first installation groove provided by the embodiment of the present application. As Figures 2 to 4 shown, the present application provides a positioning component, which is applied to a spring feeding mechanism. The spring feeding mechanism includes a spring 700. The positioning component includes: a positioning block 100, a limit stop block 200, and a positioning component. The positioning block 100 is provided with a positioning groove 110 and a first installation groove 120, and the first installation groove 120 communicates with the positioning groove 110.

[0065] The positioning groove 110 can be a groove provided on the positioning block 100, and the positioning groove 110 can communicate with the discharge port of the linear vibrator 600. In this way, the spring 700 conveyed by the linear vibrator 600 can enter the positioning block 100. The dimension of the positioning groove 110 along the moving direction of the slider 300 can be the same as the diameter of the spring 700, or the dimension of the positioning groove 110 along the moving direction of the slider 300 can be slightly larger than the diameter of the spring 700. In this way, after the spring 700 enters the positioning groove 110, it can be limited in the radial direction of the spring 700 by the positioning groove 110. The first installation groove 120 can be a through groove provided on the positioning block 100, and the opening direction of the first installation groove 120 is different from that of the positioning groove 110. Part of the first installation groove 120 communicates with the positioning groove 110.

[0066] Since multiple springs 700 can be conveyed simultaneously within the linear vibrator 600, after one of the springs 700 enters the positioning groove 110, the remaining springs 700 can squeeze the spring 700 within the positioning groove 110. In this way, the spring 700 can be limited in position in the conveying direction of the spring 700.

[0067] Figure 5 Schematic diagram of the structure of the limiting stop provided by the embodiment of the present application. Figure 6 is Figure 5 the enlarged view of part A in. As Figures 4 to 6 shown, the limiting stop 200 is provided on one side of the positioning block 100. A positioning protrusion 210 is provided on the side of the limiting stop 200 facing the positioning groove 110. The positioning protrusion 210 is located on the rotation path of the end of the spring 700 close to the limiting stop 200.

[0068] The limiting stop 200 can be fixedly connected to the side of the positioning block 100 away from the linear vibrator 600. The limiting stop 200 can limit the position of the spring 700. In this way, the probability of the problem that the spring 700 falls out of the positioning groove 110 can be reduced. Moreover, a through groove for installing a proximity detector is also provided on the limiting stop 200.

[0069] Figure 7 Schematic diagram of the structure of the slider provided by the embodiment of the present application. As Figure 3 、 Figure 4 、 Figure 6 and Figure 7 shown, the positioning assembly includes a slider 300, and the slider 300 is movably arranged in the first installation groove 120. The slider 300 can drive the spring 700 located in the positioning groove 110 to rotate, so that the end of the spring 700 close to the limiting stop 200 is limited by the positioning protrusion 210.

[0070] The slider 300 can be in the shape of a long strip. The slider 300 can be slidably arranged in the first installation groove 120. As Figure 3 and Figure 4 shown, there are two states during the use of the slider 300, including the initial state and the moving state. The slider 300 in the initial state partially shields the positioning groove 110. When in the moving state, the slider 300 is partially located in the first installation groove 120, and the slider 300 does not shield the positioning groove 110. During the process of the slider 300 changing from the initial state to the moving state, the side wall of the slider 300 facing the positioning groove 110 abuts against the spring 700, so that the slider 300 can drive the spring 700 to rotate.

[0071] During the rotation of the spring 700, one end of the spring 700 close to the limit stop 200 can abut against the positioning protrusion 210 provided on the limit stop 200. At this time, one end of the spring 700 close to the limit stop 200 is limited by the positioning protrusion 210, and the spring 700 is in the correct installation state.

[0072] In summary, the positioning component provided by the present application sets the positioning protrusion 210 on the limit stop 200, sets the first installation groove 120 on the positioning block 100, and sets the movable slider 300 in the first installation groove 120. When the slider 300 moves along the first installation groove 120, the slider 300 can drive the spring 700 to rotate until one end of the spring 700 close to the limit stop 200 abuts against the positioning protrusion 210. At this time, the spring 700 is limited, and the spring 700 is in the correct installation state. In this way, when the spring 700 is installed in the tripping module, it can just be stuck in two turns in the installation groove of the tripping module, thereby reducing the fluctuation range of the tripping force value of the circuit breaker and improving the use reliability of the circuit breaker.

[0073] When the slider 300 moves along the first installation groove 120, the side wall of the slider 300 may not contact the groove wall of the first installation groove 120.

[0074] Such as Figure 2 、 Figure 3 And Figure 7 As shown, the side wall of the slider 300 may also be in sliding contact with the groove wall of the first installation groove 120.

[0075] When the slider 300 moves along the first installation groove 120, only one side wall of the slider 300 may be in sliding contact with the groove wall of the first installation groove 120, or multiple side walls of the slider 300 may be in sliding contact with the groove wall of the first installation groove 120.

[0076] Through the above settings, the groove wall of the first installation groove 120 can play a limiting role on the slider 300. When the side wall of the slider 300 is in sliding contact with the groove wall of the first installation groove 120, the probability of the slider 300 shaking in the first installation groove 120 can be reduced, thereby improving the stability of the slider 300 when moving out of the first installation groove 120. In this way, when the slider 300 drives the spring 700 to rotate, the rotation process of the spring 700 is more stable.

[0077] In some possible designs, at least one protrusion is provided on the side of the slider 300 facing the positioning groove 110. The protrusion abuts against the spring 700.

[0078] On one side of the slider 300 facing the positioning groove 110, a plurality of protrusions may be provided. The protrusions may protrude slightly from the side wall of the slider 300. The protrusions may be dot-shaped, block-shaped or striped. When the plurality of protrusions are all striped, the plurality of striped protrusions may be arranged at intervals on the slider 300, or the plurality of striped protrusions may be arranged to cross each other on the slider 300.

[0079] The protrusions may abut against the spring 700 located in the positioning groove 110. Thus, when the slider 300 moves along the first installation groove 120, by using the frictional force between the protrusions and the spring 700, and under the condition that the positioning groove 110 limits the spring 700, the spring 700 can rotate within the positioning groove 110.

[0080] In summary, by providing protrusions on one side of the slider 300 facing the positioning groove 110, the roughness of the side wall of the slider 300 facing the positioning groove 110 can be increased, thereby increasing the frictional force between the slider 300 and the spring 700. When the protrusions abut against the spring 700, the spring 700 can be driven to rotate by using the frictional force between the protrusions and the spring 700 when the slider 300 moves along the first installation groove 120.

[0081] As Figure 2 and Figure 7 shown, a relief groove 121 is provided on one side of the first installation groove 120 facing the positioning groove 110. The protrusions are located within the relief groove 121.

[0082] The relief groove 121 may be a blind groove provided on one side of the first installation groove 120 facing the positioning groove 110. The depth of the relief groove 121 may be selected according to the protruding situation of the protrusions relative to the side wall of the slider 300. When the slider 300 moves along the first installation groove 120, the protrusions can move along the relief groove 121.

[0083] In summary, since the protrusions are provided on the side wall of the slider 300 and the slider 300 is in sliding contact with the groove wall of the first installation groove 120, a relief groove 121 that can accommodate the protrusions is provided in the first installation groove 120. In this way, the probability of interference between the groove wall of the first installation groove 120 and the protrusions when the slider 300 moves along the first installation groove 120 can be reduced. The probability of the problem that the slider 300 is stuck in the first installation groove 120 and cannot move due to the interference between the groove wall of the first installation groove 120 and the protrusions is reduced, and the reliability of the slider 300 in use is increased.

[0084] Figure 8 This is the assembly drawing of the slider and the friction block provided by the embodiment of the present application. As Figure 3 , Figure 7 and Figure 8As shown in the figure, the positioning component includes a friction block 400. The slider 300 is provided with a second installation groove 310, and the second installation groove 310 communicates with the positioning groove 110. The friction block 400 is arranged in the second installation groove 310. The side of the friction block 400 facing the positioning groove 110 protrudes from the slider 300, and the side of the friction block 400 facing the positioning groove 110 abuts against the spring 700.

[0085] The second installation groove 310 can be a through groove provided on the slider 300, or the second installation groove 310 can be a blind groove provided on the slider 300. When the second installation groove 310 is a blind groove, the opening direction of the second installation groove 310 faces the positioning groove 110. The second installation groove 310 can partially communicate with the positioning groove 110, or the second installation groove 310 can completely communicate with the positioning groove 110, or when the slider 300 moves along the first installation groove 120, the second installation groove 310 can communicate with the positioning groove 110.

[0086] The friction block 400 can be a block structure arranged in the second installation groove 310. The friction block 400 can be in interference fit with the second installation groove 310, or the friction block 400 can be clamped in the second installation groove 310. In this way, when the friction block 400 is excessively worn or the friction block 400 ages, the friction block 400 can be removed in time for replacement, which can improve the service reliability of the slider 300.

[0087] In summary, by providing the second installation groove 310 on the slider 300 and arranging the friction block 400 in the second installation groove 310, the slider 300 can drive the spring 700 to rotate through the frictional force between the friction block 400 and the spring 700. Moreover, arranging the friction block 400 can reduce the probability of direct contact between the slider 300 and the spring 700, improve the service life of the slider 300, and also reduce the later maintenance cost of the positioning component.

[0088] As Figure 2 and Figure 4 shown in the figure, a relief groove 121 is provided on the side of the first installation groove 120 facing the positioning groove 110. The part of the friction block 400 protruding from the slider 300 is located in the relief groove 121.

[0089] The relief groove 121 can be a blind groove provided on the side of the first installation groove 120 facing the positioning groove 110, and the depth of the relief groove 121 can be selected according to the protrusion of the friction block 400 relative to the side wall of the slider 300. When the slider 300 moves along the first installation groove 120, the friction block 400 can move along the relief groove 121.

[0090] In summary, the slider 300 is in sliding contact with the groove wall of the first installation groove 120, and the friction block 400 protrudes from the side wall of the slider 300. A relief groove 121 capable of accommodating the friction block 400 can be provided in the first installation groove 120. In this way, when the slider 300 moves along the first installation groove 120, the probability of interference between the groove wall of the first installation groove 120 and the friction block 400 can be reduced. The probability of the problem that the slider 300 is stuck in the first installation groove 120 and cannot move due to the interference between the groove wall of the first installation groove 120 and the friction block 400 is reduced, and the reliability of the slider 300 in use is increased.

[0091] Figure 9 This is a partial structural schematic diagram of the positioning block and the spring assembly provided by the embodiment of the present application. Figure 10 is Figure 9 the enlarged view of part B in Figure 6 、 Figure 9 and Figure 10 As shown, the positioning protrusion 210 includes a guiding surface 211 and a cut-off surface 212. The guiding surface 211 and the cut-off surface 212 are adjacent in position. The guiding surface 211 can guide one end of the spring 700 close to the limiting block 200, and the cut-off surface 212 can limit one end of the spring 700 close to the limiting block 200.

[0092] The guiding surface 211 and the cut-off surface 212 can be two surfaces of the positioning protrusion 210. The guiding surface 211 can be a plane, and the guiding surface 211 can also be a convex arc surface. The cut-off surface 212 can be a plane. The guiding surface 211 can be arranged at an obtuse angle with the side wall of the limiting block 200 facing the positioning groove 110. The cut-off surface 212 can be arranged at a 90° angle with the side wall of the limiting block 200 facing the positioning groove 110. With such an arrangement, when the spring 700 rotates, the guiding surface 211 will not block one end of the spring 700 close to the limiting block 200, and the guiding surface 211 can also play a guiding role for one end of the spring 700 close to the limiting block 200, while the cut-off surface 212 can block and limit one end of the spring 700 close to the limiting block 200.

[0093] In summary, the setting of the guiding surface 211 not only does not block one end of the spring 700 close to the limiting block 200 when the spring 700 rotates, but also can guide one end of the spring 700 close to the limiting block 200. In this way, the difficulty of the spring 700 rotating in the positioning groove 110 can be reduced. The setting of the cut-off surface 212 can limit one end of the spring 700 close to the limiting block 200, thereby limiting the rotation of the spring 700. When one end of the spring 700 close to the limiting block 200 is limited by the cut-off surface 212, the initial installation position of the spring 700 is corrected.

[0094] Figure 11 This is a schematic structural diagram of the positioning component provided by the embodiment of the present application. As Figure 11 shown, the positioning component further includes a driving member 500, and a driving shaft 510 of the driving member 500 is connected to the slider 300.

[0095] The driving member 500 can be disposed on one side of the slider 300, and the driving member 500 can drive the slider 300 to move along the first installation groove 120. The driving shaft 510 can be a shaft-like structure provided by the driving member 500 facing the slider 300. The driving shaft 510 can be connected to the slider 300 in a threaded connection manner.

[0096] In summary, the setting of the driving member 500 can reduce the labor cost required for correcting the initial installation position of the spring 700, and further, the opening or closing of the driving member 500 can be controlled by the controller, so that the operation process of the slider 300 can be more accurate, the reliability of the slider 300 in use is improved, and thus the reliability of the positioning component in use is improved.

[0097] Please continue to refer to Figure 11 shown, the driving member 500 is a cylinder or a hydraulic cylinder, and the driving shaft 510 is a piston rod.

[0098] One end of the piston rod can be connected to the piston of the cylinder or the hydraulic cylinder, and the other end of the piston rod can be connected to the slider 300.

[0099] Through the above settings, the cylinder and the hydraulic cylinder have the advantages of stable power output, fast action speed, and high safety. Selecting a cylinder or a hydraulic cylinder to drive the slider 300 to move in the first installation groove 120 can improve the reliability of the slider 300 in use, and thus can improve the reliability of the positioning component in use.
