Description

Technical Field

[0001] The present application relates to the technical field of workpiece processing, and particularly relates to a torsion spring limiting component of a workpiece processing device and a workpiece processing device. Background Art

[0002] In the related art, a workpiece processing device includes a power device, a driving device, and a cutting device. The power device includes a power motor and a first gear assembly. The driving assembly includes a second gear assembly, a moving plate structure, a connecting rod, and other components. The power motor can drive the first gear assembly to rotate. The rotation of the first gear assembly drives the rotation of the second gear assembly, and the rotation of the second gear assembly can drive the moving plate structure to move up and down along the connecting rod. The movement of the moving plate structure can drive the cutting device to move, so as to move the cutting tool in the cutting device to the surface of the workpiece for operation or reset the cutting tool.

[0003] Chinese Patent Invention No. CN201880058793.9 discloses a part of a cutting device of a manufacturing device, which includes at least one spring (126, 128, 134). At least one spring connects a support member moving device (110) to a support member (106). At least one spring (126, 128, 134) includes at least one non-linear spring (126, 128) around a support rod (108). Each spring (126, 128, 134) is jointly restricted by the support member moving device (110) and the support member (106), and is restricted along the deformation direction of each spring (126, 128, 134).

[0004] When the support member moving device (110) and the support member (106) are driven by the motor 140 and the gear 114, a relative position change will occur, changing the state of the spring (126, 128, 134). The spring (126, 128, 134) is jointly limited by the support member moving device (110) and the support member (106), and at the same time, the spring (126, 128, 134) will also change its shape due to the relative position change of the support member moving device (110) and the support member (106).

[0005] When the support member moving device (110) and the support member (106) are driven by the motor 140 and the gear 114 to generate a relative position change, the limiting effect on the spring (126, 128, 134) decreases. Summary of the Invention

[0054] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0055] Referring to "embodiment" or "embodiment" herein means that the specific features, structures or characteristics described in connection with the embodiment or embodiment may be included in at least one embodiment of the present application. The phrase appears at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0056] As Figure 1 and Figure 2 shown, Figure 1 is a schematic structural diagram of a workpiece processing device provided by an embodiment of the present application, Figure 2 For Figure 1 A partial structural diagram of the shown workpiece processing device. The workpiece processing device 1000 may include a housing 1100, a cover plate 1200, a driving component 1300, a transmission component 1400, a cutting component 1500, and a suction and discharge roller 1600.

[0057] The housing 1100 may include a cavity 1110 and an opening 1120. The cover plate 1200 and the housing 1100 are rotatably connected, that is, the cover plate 1200 can rotate relative to the housing 1100, so as to be able to cover the opening 1120 or open the opening 1120.

[0058] The workpiece processing device 1000 may include a workpiece processing table 1130, and the workpiece processing table 1130 is used to place workpieces to be processed such as metal parts, paper, leather, wood boards, food and other workpieces. The workpiece processing table 1130 may be located at the position of the opening 1120 to facilitate the placement of the workpieces to be processed. Exemplarily, at least part of the workpiece processing table 1130 is located on the inner surface of the bottom of the housing 1100. In an alternative embodiment of the present application, when the cover plate 1200 opens the opening 1120, the inner side surface of the cover plate 1200 can be substantially flush with the inner surface of the bottom of the housing 1100, and the inner side surface of the cover plate 1200 can be used as an extension part of the workpiece processing table 1130.

[0059] It can be understood that the inner surface of the housing 1100 is the surface used to form the cavity 1110. It can also be understood that the bottom of the housing 1100 is the part of the housing 1100 placed on the installation site such as a desktop when the workpiece processing device 1000 is in use.

[0060] The driving assembly 1300, the transmission assembly 1400, the cutting assembly 1500, and the suction and discharge roller 1600 can all be arranged in the cavity 1110. Among them, both the cutting assembly 1500 and the suction and discharge roller 1600 are located above the workpiece processing table 1130.

[0061] The suction and discharge roller 1600 can be sleeved on a connecting rod 1700, and the suction and discharge roller 1600 can rotate on the connecting rod 1700 to realize suction and discharge. There is at least one suction and discharge roller 1600. For example, there are two suction and discharge rollers 1600, and the two suction and discharge rollers 1600 are sleeved on both ends of the connecting rod 1700. Among them, the connecting rod 1700 is installed on the housing 1100. Exemplarily, both the connecting rod 1700 and the suction and discharge roller 1600 are located below the plane where the cutting assembly 1500 is located.

[0062] It should be noted that the plane where the cutting assembly 1500 is located can be substantially parallel to the bottom of the housing 1200, and the plane where the cutting assembly 1500 is located can also be substantially parallel to the workpiece processing table 1130.

[0063] The cutting assembly 1500 can move relative to the workpiece processing table 1130 to facilitate the processing of the items placed on the workpiece processing table.

[0064] Exemplarily, the cutting assembly 1500 can move parallel to the plane where the workpiece processing table 1130 is located. For example, the cutting assembly 1500 can be penetrated by one or more rod structures to achieve the positioning of the cutting assembly 1500, or rather, the restriction of the cutting assembly 1500. For example, there are two rod structures, including a first positioning rod 1800 and a second positioning rod 1900. Both the first positioning rod 1800 and the second positioning rod 1900 can penetrate the cutting assembly 1500, so that the cutting assembly 1500 can move along the length direction of the first positioning rod 1800 and the length direction of the second positioning rod 1900.

[0065] It can be understood that the first positioning rod 1800 has a length direction, and the second positioning rod 1900 also has a length direction, and the length directions of the first positioning rod 1800 and the second positioning rod 1900 are the same. In the embodiment of the present application, the length direction of the first positioning rod 1800 is defined as the lateral direction. It should be noted that the length direction of the first positioning rod 1800 can be the same as the length direction of the driving rod 30 in the driving assembly 1300.

[0066] In an optional embodiment of the present application, the lateral movement range of the cutting assembly 1500 is restricted. For example, the lateral movement range of the cutting assembly 1500 is restricted between two suction and discharge rollers 1600 and will not collide with the suction and discharge rollers 1600.

[0067] The transmission assembly 1400 can be drivingly connected to the cutting assembly 1500, and the transmission assembly 1400 can drive the cutting assembly 1500 to move along the length direction of the first positioning rod 1800 and the length direction of the second positioning rod 1900. In an optional embodiment of the present application, the transmission assembly 1400 can include a transmission belt. One side of the transmission belt is provided with a plurality of teeth, and the plurality of teeth can be engaged with a plurality of gears. The plurality of gears can be connected to the motor and the cutting assembly 1500, so as to realize that the transmission belt drives the cutting assembly 1500 to move along the length direction of the first positioning rod 1800 and the length direction of the second positioning rod 1900.

[0068] The driving assembly 1300 is drivingly connected to the cutting assembly 1500, and the driving assembly 1300 can drive a part of the cutting assembly 1500, such as the part with a cutting tool, to move vertically. Among them, the vertical direction can be understood as the direction substantially perpendicular to the workpiece processing platform 1130. When a part of the cutting assembly 1500 is driven by the replacement assembly 1300 to move vertically, a distance change occurs between the part of the cutting assembly 1500 moving vertically and the workpiece processing platform 1130, so as to facilitate the cutting assembly 1500 to process the articles placed on the workpiece processing platform 1130 and facilitate the reset of the cutting assembly 1500.

[0069] For example, the driving assembly 1300 may include a driving motor and a driving rod 30. The driving motor is drivingly connected to the driving rod 30. The driving rod 30 passes through the cutting assembly 1500 and can drive a part of the cutting assembly 1500, such as the part with the cutting tool, to move vertically.

[0070] Among them, the cutting assembly 1500 may include a lateral movement housing 1510, a vertical movement housing 1520, a cutting tool 1530, a torsion spring 20, and a torsion spring limiting assembly 10. The lateral movement housing 1510 is connected to the first positioning rod 1800 and the second positioning rod 1900. The limiting assembly 10 is sleeved on the driving rod 30, and the limiting assembly 10 is disposed within the lateral movement housing 1510. The torsion spring 20 is sleeved on the limiting assembly 10, and the torsion spring 20 is limited by the limiting assembly 10, such as both ends of the torsion spring 20 being limited by the limiting assembly 10. The torsion spring 20 is drivingly connected to the vertical movement housing 1520, and the cutting tool 1530 is installed on the vertical movement housing 1520. When the driving rod 30 is driven by the driving motor, it can rotate, driving the limiting assembly 10 to rotate together with the driving rod 30, thereby driving the torsion spring 20 to deform. When the lateral movement housing 1510 does not move vertically, the vertical movement housing 1520 is driven by the torsion spring 20 to move vertically relative to the lateral movement housing 1510.

[0071] In an alternative embodiment of the present application, please refer to Figure 3 , Figure 3 is Figure 1 a partial structural schematic diagram of the workpiece processing equipment shown. The workpiece processing equipment 1000 may further include a guiding kit 1540. The guiding kit 1540 is drivingly connected to the torsion spring 20, and the torsion spring 20 can drive the guiding kit 1540 to move vertically.

[0072] Exemplarily, the guiding kit 1540 may include a guiding rod and a rod sleeve. The upper and lower ends of the guiding rod are fixed to the lateral movement housing 1510, and the rod sleeve is fixedly connected to the vertical movement housing 1520 and moves within the vertical space defined by the lateral movement housing 1510 and the guiding rod. Specifically, the torsion spring 20 is drivingly connected to the rod sleeve, and the torsion spring 20 drives the rod sleeve to move, so that the rod sleeve drives the vertical movement housing 1520 to move. It can be understood that the guiding rod and the rod sleeve are a specific example of the guiding kit 1540 in the embodiments of the present application. The embodiments of the present application do not limit how to achieve the vertical movement of the vertical movement housing 1520. It should be understood that all the ways in the art by which the driving assembly 1300 can drive the vertical movement housing 1520 to move vertically are within the protection scope of the embodiments of the present application.

[0073] The vertical movement of the guiding kit 1540 is restricted within a certain range. For example, the guiding kit 1540 is restricted between the two ends of the lateral movement housing 1510. The guiding kit 1540 is fixedly connected to the vertically moving housing 1520. When the torsion spring 20 drives the guiding kit 1540 to move vertically, it can also drive the vertically moving housing 1520 to move vertically. That is, the torsion spring 20 drives the guiding kit 1540 and the vertically moving housing 1520 to move vertically together.

[0074] In an alternative embodiment of the present application, please refer to Figure 4 , Figure 4 which is Figure 1 a partial structural schematic diagram of the workpiece processing equipment shown. Figure 4 It shows an alternative embodiment of the torsion spring 20 and the limiting component 10 in the cutting component 1500 of the embodiment of the present application, which does not constitute a limitation on the torsion spring 20 and the limiting component 10. Among them, the driving rod 30 has a first end 31 and a second end 32. The driving motor is drivingly connected to the first end 31. For example, the driving rod 30 also has teeth 37 near the first end 31, and the teeth 27 are directly or indirectly engaged with the driving motor. Thus, the driving motor can drive the driving rod 30 to rotate.

[0075] The limiting component 10 is sleeved on the driving rod 30 and can rotate together with the driving rod 30. For example, the outer surface of the driving rod 30 is a non-cylindrical structure, or the cross-section of the driving rod 30 is non-circular. The surface of the position where the limiting component 10 is sleeved on the driving rod 30 is adapted thereto. Thus, when the driving rod 30 rotates, it can drive the limiting component 10 to rotate together. In an alternative embodiment of the present application, the outer surface of the driving rod 30 includes at least one flat surface 33 and at least one arc surface 34. A flat surface 33 and an arc surface 34 are connected, and the connection position of the flat surface 33 and the arc surface 34 forms an edge 35. Correspondingly, the surface of the position where the limiting component 10 is sleeved on the driving rod 30 is adapted to it. The following will be described in detail in combination with other schematic diagrams of the limiting component 10.

[0076] As Figure 5 shown, Figure 5 it is a schematic structural diagram of the limiting component of the embodiment of the present application for limiting the torsion spring. The second end 32 of the driving rod 30 can penetrate the limiting component 10. For example, the second end 32 of the driving rod 30 can pass through the through space 500 of the limiting component 10. The first end 31 of the driving rod 30 cannot penetrate the limiting component 10. For example, a blocking portion 36 is provided near the first end 31 of the driving rod 30, and the blocking portion 36 can prevent the limiting component 10 from detaching from the first end 31 of the driving rod 30.

[0077] The torsion spring 20 is sleeved on the limiting component 10. For example, the torsion spring 20 is installed in the limiting space 400 of the limiting component 10. The two ends of the torsion spring 20, such as the first end 21 and the second end 22, are respectively restricted by the limiting component 10. The torsion spring 20 also has a free end 23, and the free end 23 is connected to the vertical moving shell 1520. For example, the free end 23 is connected to the vertical moving shell 1520 through the guide rod 1540. When the driving rod 30 rotates, the driving limiting component 10 rotates together. Since the first end 21 and the second end 22 of the torsion spring 20 are respectively restricted by the limiting component 10, the torsion spring 20 deforms, such as the free end 23 driving the guide rod 1540 and the vertical moving shell 1520 to move vertically.

[0078] Next, in combination with the structural schematic diagram of the limiting component 10, the structure of the limiting component 10 for limiting the torsion spring 20 will be described in detail.

[0079] Please refer to Figure 6 and Figure 7 , Figure 6 which is a three-dimensional view of the limiting component provided by the embodiment of the present application, Figure 7 and Figure 6 is a cross-sectional view of the limiting component shown in. The limiting component 10 includes a first limiting portion 100, a second limiting portion 200, and a sleeving portion 300. The first limiting portion 100 is connected to the sleeving portion 300, the sleeving portion 300 is connected to the second limiting portion 200. The first limiting portion 100 and the second limiting portion 200 are located at both ends of the sleeving portion 300. One end surface of the first limiting portion 100, one end surface of the second limiting portion 200, and the outer surface of the sleeving portion 300 jointly define a limiting space 400. The torsion spring 20 is installed in the limiting space 400, and the torsion spring 20 is jointly limited by one end surface of the first limiting portion 100, one end surface of the second limiting portion 200, and the outer surface of the sleeving portion 300.

[0080] Among them, the two ends of the torsion spring 20 are respectively restricted by the first limiting portion 100 and the second limiting portion 200. For example, the first limiting portion 100 includes a first card slot 110, and the second limiting portion 200 includes a second card slot 210. The two ends of the torsion spring 20 are respectively fixed by the first card slot 110 and the second card slot 210. Specifically, the first end 21 of the torsion spring 20 is installed in the first card slot 110, and the second end 22 of the torsion spring 20 is installed in the second card slot 210. Thus, the limiting component 10 can not only limit the two ends of the torsion spring 20, but also fix the two ends of the torsion spring 20. The effect of stably restricting the torsion spring 20 is achieved. Even if the torsion spring 20 deforms starting from its free end 23, the two ends of the torsion spring 20 are always restricted by the limiting component 10, including limiting and fixing, and the torsion spring 20 can be stably restricted, improving the stability of the torsion spring 20.

[0081] In an alternative embodiment of the present application, both the first card slot 110 and the second card slot 210 can be through holes. It should be noted that it is also possible for both the first card slot 110 and the second card slot 210 to be other structures, such as both the first card slot 110 and the second card slot 210 being blind holes. In other alternative embodiments, one of the first card slot 110 and the second card slot 210 is a through hole and the other is a blind hole.

[0082] The first card slot 110 and the second card slot 210 can be arranged opposite to each other, such as the first card slot 110 and the second card slot 210 being symmetrically arranged with respect to the socket part 300. It can be understood that the first card slot 110 and the second card slot 210 can also be arranged in a staggered manner.

[0083] Among them, the limiting component 10 has a through space 500, and the through space 500 includes a first through hole 510, a second through hole 520, and a third through hole 530. The first through hole 510 is opened in the first limiting part 100, the second through hole 520 is opened in the second limiting part 200, and the third through hole 530 is opened in the socket part 300. It can also be understood that the first limiting part 100 includes the first through hole 510, the second limiting part 200 includes the second through hole 520, and the socket part 300 includes the third through hole 530. The first through hole 510, the second through hole 520, and the third through hole 530 are communicated to jointly define a through space 500. The through space 500 is used for a driving rod such as the driving rod 30 to pass through, or in other words, the through space 500 is used to place a part of the driving rod 30.

[0084] Exemplarily, the projection of the through space 500 along the length direction L of the torsion spring limiting component 10 is non-circular. Figure 4 Combined with the fact that the length direction L of the torsion spring limiting component 10 is the same as the length direction of the driving rod 30, and the length direction L of the torsion spring limiting component 10 is the same as the length direction of the first positioning rod 1800. In the embodiment of the present application, the transverse direction of the cutting component 1500 is the same as the length direction L of the torsion spring limiting component 10.

[0085] The first limiting part 100 and the socket part 300 are detachably connected, and / or the second limiting part 200 and the socket part 300 are detachably connected. It can be understood that at least one of the first limiting part 100 and the second limiting part 200 is detachably connected to the socket part 300, so that when installing the torsion spring 20, it is convenient to first sleeved the torsion spring 20 on the socket part 300, and then fix at least one of the first limiting part 100 and the second limiting part 200 to the socket part 300 to realize the limiting and fixing of the torsion spring 20.

[0086] In an alternative embodiment of the present application, the first limiting portion 100, the socket portion 300, and the second limiting portion 200 can all be detachably connected. For example, the first limiting portion 100 and the socket portion 300 are detachably connected, and the second limiting portion 200 and the socket portion 300 are detachably connected.

[0087] In an alternative embodiment of the present application, the first limiting portion 100 and the socket portion 300 are fixedly connected, and the second limiting portion 200 and the socket portion 300 are detachably connected. The following will describe in detail the fixed connection between the first limiting portion 100 and the socket portion 300, and the detachable connection between the second limiting portion 200 and the socket portion 300 in combination with other structural schematic diagrams of the limiting assembly 10. It can be understood that it is also possible that the first limiting portion 100 and the socket portion 300 are detachably connected, and the second limiting portion 200 and the socket portion 300 are fixedly connected.

[0088] Please refer to Figures 8 to 13 , Figure 8 which is an exploded schematic diagram of a limiting assembly provided by an embodiment of the present application, Figure 9 which is a structural schematic diagram of the integral setting of the first limiting portion and the socket portion in the limiting assembly provided by an embodiment of the present application, Figure 10 which is a structural schematic diagram of another angle of the integral setting of the first limiting portion and the socket portion in the limiting assembly provided by an embodiment of the present application, Figure 11 which is a structural schematic diagram of the second limiting portion in the limiting assembly provided by an embodiment of the present application, Figure 12 is Figure 11 an enlarged view of the partial A in the second limiting portion shown, Figure 13 which is a structural schematic diagram of another angle of the second limiting portion in the limiting assembly provided by an embodiment of the present application.

[0089] In an alternative embodiment of the present application, the first limiting portion 100 and the socket portion 300 are integrally provided, and the second limiting portion 200 and the socket portion 300 are detachably connected. The socket portion 300 includes a main body structure 310 and a connecting structure 320. One end of the main body structure 310 is integrally provided with the first limiting portion 100, and the other end of the main body structure 310 is integrally provided with the connecting structure 320. The second limiting portion 200 is at least partially sleeved on the connecting structure 320, and the second limiting portion 200 is fixedly connected to the connecting structure 320.

[0090] For example, the connecting structure 320 is provided with a clamping groove 330, and the opening of the clamping groove 330 is located at one end of the socket part 300. The second limiting part 200 includes a clamping block 220, and the clamping block 220 can be placed in the clamping groove 330. When the second limiting part 200 is sleeved on the connecting structure 320, the clamping block 220 cooperates with the clamping groove 330 to fixedly install the second limiting part 200 on the socket part 300, realizing the fixation of the second limiting part 200 and the socket part 300. The number of the clamping grooves 330 is the same as the number of the clamping blocks 220. For example, there are two clamping grooves 330 and two clamping blocks 220. The two clamping grooves 330 are arranged oppositely, the two clamping blocks 220 are arranged oppositely, and one clamping block 220 is clamped into one clamping groove 330.

[0091] A part of the second limiting part 200 is sleeved on the connecting structure 320. For example, the second limiting part 200 includes a socket structure 230 and a blocking structure 240. The socket structure 230 is sleeved on the connecting structure 320, and the connecting structure 320 abuts against the blocking structure 240. For example, the end of the connecting structure 320 abuts against the blocking structure 240. Wherein, the clamping block 220 is arranged on the inner surface of the socket structure 230 and the clamping block 220 is connected to the blocking structure 240, so that the strength of the clamping block 220 can be enhanced, and at the same time, the strength of the socket structure 230 and the blocking structure 240 can also be enhanced.

[0092] In an alternative embodiment of the present application, the second clamping groove 210 is located at the root position of the clamping block 220, so as to increase the stability of the fixed connection between the second limiting part 200 and the second end 22 of the torsion spring 20. It can be understood that the structure of the first limiting part 100 can be the same as or different from the structure of the second limiting part 200. When the structure of the first limiting part 100 is the same as the structure of the second limiting part 200, the first clamping groove 110 of the first limiting part 100 can be located at the root position of the clamping block of the first limiting part 100.

[0093] In an alternative embodiment of the present application, the inner surface of the blocking structure 240 includes a flat surface and an arc surface, and the top surface of the clamping block 220 is flush with the flat surface of the blocking structure 240. The inner surface of the blocking structure 240 can be understood as the surface where the limiting component 10 cooperates with the driving rod 30.

[0094] For example, the limiting component 10 includes a wall, and the wall surrounds to form a through space 500. Or it can be said that the wall used to form the through space 500 at least includes an arc wall and a flat wall, and the arc wall and the flat wall are connected. The arc wall of the limiting component 10 is connected with the arc surface 34 of the driving rod 30, and the flat wall of the limiting component 10 is connected with the flat surface 33 of the driving rod 30. Thereby, it can be realized that the limiting component 10 will not rotate along the axial direction of the driving rod 30 on the driving rod 30, or it can be said that the rotation of the limiting component 10 along the axial direction of the driving rod 30 is restricted.

[0095] Such as two arc-shaped walls and two flat walls. The two flat walls are arranged oppositely, the two arc-shaped walls are arranged oppositely, and one flat wall connects the two arc-shaped walls. In the embodiment of the present application, the part of the wall located on the second limiting part 200 is taken as an example for illustration. The wall 260 surrounds to form a through space 500, or in other words, the wall 260 used to form the through space 500 includes two arc-shaped walls 262 and two flat walls 261. The two flat walls 261 are arranged oppositely, the two arc-shaped walls 262 are arranged oppositely, and one flat wall 261 connects the two arc-shaped walls 262. One flat wall 261 can be connected with the plane 33 in a matching manner, and one arc-shaped wall 262 can be connected with one arc surface 34 in a matching manner.

[0096] In an alternative embodiment of the present application, one arc-shaped wall 262 includes a first arc segment 2621, a second arc segment 2622 and a third arc segment 2623. The first arc segment 2621 and the third arc segment 2623 are connected to the second arc segment 2622, and the first arc segment 2621 and the third arc segment 2623 are located on both sides of the second arc segment 2622. The second arc segment 2622 is matched with the arc surface 34, and the radian of the second arc segment 2622 is adapted to the radian of the arc surface 34. Both the first arc segment 2621 and the third arc segment 2623 are matched with the edge 35 of the driving rod 30, or in other words, the edge 35 of the driving rod 30 is placed between the first arc segment 2621 and the third arc segment 2623. The shape of the edge 35 of the driving rod 30 can be the same as or different from that of the first arc segment 2621 and the third arc segment 2623.

[0097] Among them, the first arc segment 2621 and the third arc segment 2623 are symmetrically arranged with respect to the second arc segment 2622.

[0098] Among them, the radian of the first arc segment 2621 is different from that of the second arc segment 2622, and the radian of the third arc segment 2623 is different from that of the second arc segment 2622.

[0099] It can be understood that for the matching shapes of the flat wall and the arc-shaped wall, all or part of them can be easily applied to the corresponding positions of the first limiting component and the corresponding positions inside the socket part.

[0100] It should be noted that the limiting component 10 is installed in the transverse moving shell 1510 of the cutting component such as the cutting component 1500. The limiting component 10 can be fixedly connected with the transverse moving shell 1510 in a clamping and matching manner, so that additional components can be saved to limit the limiting component 10 in the transverse moving shell 1510. Such as the first limiting part 100 and / or the second limiting part 200 can be clamped and matched with the transverse moving shell 1510.

[0101] In an alternative embodiment of the present application, the second limiting portion 200 includes a first limiting boss 250, and the blocking structure 240 is disposed on the inner surface of the first limiting boss 250. The outer diameter of the first limiting boss 250 is greater than the outer diameter of the socket structure 230, so as to form a step structure 270 between the outer surface of the first limiting boss 250 and the outer surface of the socket structure 230. In an alternative embodiment of the present application, the outer diameter of the socket structure 230 is greater than the outer diameter of the main body structure 310, and a step structure is also formed between the socket structure 230 and the main body structure 310. It can be understood that the first limiting boss 250 can be engaged with the laterally moving housing 1510, such as the laterally moving housing 1510 is provided with a groove structure for installing the first limiting boss 250. The step structure 270 can place the structure of the laterally moving housing 1510, and can increase the stability of the engagement between the second limiting portion 200 and the laterally moving housing 1510.

[0102] In an alternative embodiment of the present application, the first limiting portion 100 includes a second limiting boss 120 and a third limiting boss 130. The second limiting boss 120 and the third limiting boss 130 are parallel and spaced apart from each other, so as to form a groove 140 between the second limiting boss 120 and the third limiting boss 130. It can be understood that the first limiting portion 100 can be engaged with the laterally moving housing 1510, such as the laterally moving housing 1510 is provided with a clamping structure for being installed in the groove 140 and cooperating with the second limiting boss 120 and the third limiting boss 130, so as to realize the engagement between the first limiting portion 100 and the laterally moving housing 1510.

[0103] It can be understood that both the second limiting boss 120 and the third limiting boss 130 can be engaged with the laterally moving housing 1510, such as the laterally moving housing 1510 is provided with a groove structure for installing the second limiting boss 120 and / or the third limiting boss 130.

[0104] In an alternative embodiment of the present application, the third limiting boss 130 is farther from the second limiting portion 200 than the second limiting boss 120, and the outer diameter of the second limiting boss 120 is greater than the outer diameter of the third limiting boss 130. It should be noted that it is also possible that the outer diameter of the second limiting boss 120 is not greater than the outer diameter of the third limiting boss 130.

[0105] In an alternative embodiment of the present application, the socket portion 300 is a cylindrical structure, and the outer surface of the socket portion 300 is adapted to the torsion spring 20. For example, the torsion spring 20 has multiple elastic coils, and the multiple elastic coils can be sleeved on the outer surface of the socket portion 300 and can also deform following the free end 23 of the torsion spring 20.
