Description

Technical Field

[0001] The present invention relates to the technical field of cable joint connection structures, and particularly to a charging pile cable joint connection structure. Background Art

[0002] Currently, new energy vehicles are developing rapidly, and charging pile facilities are being vigorously built in cities across the country. However, there is a serious problem with the built charging piles - when charging an electric vehicle, the repeated dragging of the cable will continuously tug at the joints on the box wall of the charging pile, causing damage and deformation at the interfaces on the box wall, and even loosening or falling off of the cable glands, thus significantly shortening the lifespan of the charging pile.

[0003] Currently, when the charging cable passes through the box wall of the charging pile, it is directly fixed to the box wall through a cable gland, and all the pulling forces on the cable are directly transmitted to the box wall through the box wall connection. However, the box wall and the interface cannot withstand repeated pulling, so after a period of use, deformation, loosening, or even falling off of the box wall and the interface occur. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a charging pile cable joint connection structure, which includes an electrical box. A slide rail is fixedly connected to the bottom of the electrical box, a connection terminal is fixedly connected to the bottom of the slide rail, a flexible wire is fixedly connected to the bottom of the connection terminal, a clamping end is snap-connected to the end of the flexible wire away from the connection terminal, and an output wire is fixedly connected to the bottom of the clamping end. It further includes: A clamping mechanism, which is slidably connected to the inner wall of the slide rail. When an external pulling force occurs, the pulling force is transmitted to the clamping end through the output wire and is relieved by the internal components of the clamping mechanism and transferred to the position of the slide rail; A sliding mechanism, which is slidably connected to the side wall of the clamping mechanism. When the device is deformed by an external pulling force, the sliding mechanism will drive the clamping mechanism to deform again and change the contact position between the device and the output wire; A pressure mechanism, which is fixedly connected to the side wall of the clamping mechanism and provides power for the deformation of the above clamping mechanism; Among them, before use, the slide rail is first fixed to the wall. When an external force is transmitted to the clamping mechanism through the output wire, the clamping mechanism deforms and relieves the pulling force. When the external force is too large, the pulling force is transmitted to the electrical box through the slide rail, reducing the pressure on the line connection position.

[0005] Preferably, the clamping mechanism includes: A sliding component, which is slidably connected to the inner wall of the slide rail through a moving part; The moving part includes a sliding block slidably connected to the inner wall of the slide rail. A first sliding tube is fixedly connected to the side wall of the sliding block. A second sliding tube is slidably connected to the inner wall of the first sliding tube. The inner wall of the first sliding tube is fixedly connected to the outer wall of the clamping end. A limiting component, which is fixedly connected to the inner wall of the slide rail through a buckling component. The buckling component includes a fixed rod fixedly connected to the inner wall of the slide rail. A first clamping groove is formed in the side wall of the fixed rod. Among them, the depth of the lowermost first clamping groove is greater than that of the top one.

[0006] Preferably, the sliding mechanism includes: An auxiliary component, which is slidably connected to the side wall of the second sliding tube through a sliding part. The sliding part includes a transverse sliding groove formed in the side wall of the second sliding tube. A triangular sliding plate is slidably connected to the inner wall of the transverse sliding groove. A second spring is fixedly connected to the top of the triangular sliding plate. A first sliding plate is slidably connected to the inner wall of the transverse sliding groove. A linkage component, which is fixedly connected to the side wall of the first sliding plate through a driving part. The driving part includes a toothed ring fixedly connected to the side wall of the first sliding plate. A fixing plate is fixedly connected to the side wall of the slide rail. A toothed column is rotatably connected to the side wall of the fixing plate. Among them, the outer wall of the toothed column is meshed with the outer wall of the toothed ring. When the toothed column rotates, the toothed ring will force the second sliding tube to move up and down along the inner wall of the sliding block.

[0007] Preferably, the pressure mechanism includes: A driving component, which is fixedly connected to the side wall of the sliding block through a pressing part. The pressing part includes a second sliding plate fixedly connected to the side wall of the sliding block. A toothed bar is fixedly connected to the side wall of the second sliding plate. A buckling component, which is fixedly connected to the top of the fixing plate through a one-way part. The one-way part includes a sliding square tube fixedly connected to the top of the fixing plate. An inclined plane slider is slidably connected to the inner wall of the sliding square tube. A third spring is fixedly connected to the side wall of the inclined plane slider. Among them, when the sliding block slides up and down along the inner wall of the slide rail, at this time, the second sliding plate drives the linkage component to rotate through the toothed bar. The rotating force will be transmitted to the toothed ring through the toothed column, forcing the toothed ring to drive the second sliding tube to move up and down.

[0008] Preferably, the sliding component includes a first spring fixedly connected to the top of the sliding block. A fixed block is fixedly connected to the inner wall of the slide rail. The top of the first spring is fixedly connected to the bottom of the flexible wire. Among them, when the output wire is subjected to a tensile force, the output wire drives the first sliding tube and the sliding block to slide down through the clamping end. At this time, the first spring will deform and store potential energy.

[0009] Preferably, the limiting component includes a spring slider slidably connected to the side wall of the slider. An arc surface is formed at the top of the spring slider, and an inclined surface is formed at the bottom of the spring slider; The width of the arc surface is greater than the width of all the first card slots, and the width of the lowermost first card slot is greater than the width of the inclined surface; Wherein, when the spring slider slides downward, the shallower first card slot will contact the inclined surface and force the spring of the spring slider to contract and deform. When the spring slider reaches the bottommost position, the bottom plane of the spring slider will contact the plane of the deeper first card slot and limit the further downward movement of the slider.

[0010] Preferably, the auxiliary component includes a convex block fixedly connected to the inner wall of the first sliding plate; Wherein, when the toothed ring moves horizontally left and right, it will drive the convex block to move horizontally synchronously through the first sliding plate. During this process, the second spring will force the triangular sliding plate to always be in the lowest position. When the convex block moves, affected by the arc surface of the triangular sliding plate, the initial sliding resistance is relatively large. When the convex block crosses the lowest point of the triangular sliding plate, at this time, the triangular sliding plate will squeeze the plane of the convex block, causing the convex block and the first sliding plate to complete the horizontal movement quickly.

[0011] Preferably, the linkage component includes a first gear rotatably connected to the side wall of the fixed plate, and the outer wall of the first gear is meshed and connected to the outer wall of the toothed column; Wherein, when the toothed rod moves downward, the toothed rod drives the first gear to rotate through the driving component, and the first gear drives the toothed column to rotate.

[0012] Preferably, the driving component includes a barbed gear fixedly connected to the outer wall of the first gear; Wherein, the outer wall of the barbed gear is meshed and connected to the outer wall of the toothed rod. When the toothed rod moves downward, the barbed gear will rotate. When the second sliding plate moves upward, the inner inclined surface of the barbed gear will contact the plane of the second sliding plate, and the barbed gear will no longer rotate.

[0013] Preferably, the buckling component includes a second card slot formed in the side wall of the first gear; Wherein, when the toothed rod moves downward, the first gear will rotate clockwise. At this time, the inclined surface of the inclined surface slider contacts the plane of the second card slot. When the toothed rod moves upward, the plane of the inclined surface slider will contact the plane of the second card slot, restricting the rotation of the second card slot.

[0014] The present invention has the following beneficial effects: (1) During the downward sliding process of the slider of the present invention, the spring slider moves outward under the push of its own spring and forces the end of the spring slider to enter the inner wall of the first card slot. Before the spring slider reaches the bottommost position, such as Figure 5As shown, the topmost state will be presented. At this time, the inclined plane of the inclined plane still contacts the edge of the first card slot. When the sliding block moves downward, the spring slider will slide and contract. When the spring slider reaches the bottommost position, the spring slider will enter the inner wall of the deeper first card slot. At this time, the bottom plane of the spring slider will contact the plane of the first card slot, restricting the continuous downward movement of the sliding block. At this time, the external pulling force will be transmitted to the fixed rod and the slide rail through the sliding block and the spring slider. Through the application of the above components, when an external pulling force appears, the force on the clamping end and the soft wire joint position is reduced.

[0015] (2) The present invention utilizes the characteristic that the above-mentioned sliding block slides downward under the pulling force, and a sliding mechanism and a pressure mechanism are arranged inside the device. When the sliding block moves downward, the second sliding plate will drive the toothed rod to move downward synchronously. As Figure 6 shown, at this time, the toothed rod will drive the bramble gear to rotate clockwise. The bramble gear drives the toothed column to rotate counterclockwise through the first gear. The rotating toothed column will drive the toothed ring and the second sliding tube to move up and down along the inner wall of the first sliding tube for a certain distance. Through the application of the above components, it is ensured that after each pulling of the output wire, the toothed ring will drive the second sliding tube to move a small distance, changing the contact position between the inner wall of the second sliding tube and the outer wall of the output wire, and avoiding the output wire being bent multiple times at a single position, resulting in damage to the outer wall of the output wire.

[0016] (3) During the process of the toothed column driving the toothed ring to move up and down, when reaching the upper and lower arc positions of the toothed ring, the rotation of the toothed column will force the toothed ring and the first sliding plate to move horizontally along the inner wall of the horizontal chute. During the horizontal movement of the first sliding plate, the convex block will squeeze the triangular sliding plate to move up and down along the inner wall of the horizontal chute. As Figure 8 shown, the second spring will force the triangular sliding plate to always be in the lowest position. When the convex block moves, affected by the arc surface of the triangular sliding plate, the initial sliding resistance is relatively large. When the convex block crosses the lowest point of the triangular sliding plate, at this time, the triangular sliding plate will squeeze the plane of the convex block, causing the convex block and the first sliding plate to quickly complete the horizontal movement, increasing the contact force between the inner wall of the toothed ring and the toothed column. Through the application of the above components, the contact force between the toothed column and the toothed ring is ensured, and the phenomenon of tooth loosening is avoided.

[0017] (4) The present invention utilizes the characteristic that the above-mentioned bramble gear drives the first gear to rotate, and a buckle assembly is arranged inside the device. When the toothed rod moves downward, the first gear will rotate clockwise. At this time, the inclined plane of the inclined plane slider contacts the plane of the second card slot. When the toothed rod moves upward, the plane of the inclined plane slider will contact the plane of the second card slot, restricting the rotation of the second card slot. Through the application of the above components, when the toothed rod moves upward, it is prevented that the first gear rotates correspondingly, resulting in the second sliding tube sliding back and forth under the external pulling force, affecting the protection effect of the device on the output wire.

An output wire 17 is fixedly connected to the bottom of the snap connection end 16. It further includes: A snap connection mechanism 1. The snap connection mechanism 1 is slidably connected to the inner wall of the slide rail 13. When an external tensile force appears, the tensile force is transmitted to the snap connection end 16 through the output wire 17 and is relieved by the internal components of the snap connection mechanism 1 and transferred to the position of the slide rail 13; A sliding mechanism 2. The sliding mechanism 2 is slidably connected to the side wall of the snap connection mechanism 1. When an external force pulls the device to cause deformation, the sliding mechanism 2 will drive the snap connection mechanism 1 to deform again, changing the contact position between the device and the output wire 17; A pressure mechanism 3. The pressure mechanism 3 is fixedly connected to the side wall of the snap connection mechanism 1, providing power for the deformation of the above-mentioned snap connection mechanism 1; Among them, before use, the slide rail 13 is first fixed to the wall. When an external force is transmitted to the snap connection mechanism 1 through the output wire 17, the snap connection mechanism 1 deforms and relieves the tensile force. When the external force is too large, the tensile force is transmitted to the electrical box 18 through the slide rail 13, reducing the pressure on the line connection position.

[0023] The snap connection mechanism 1 includes: A sliding component 11. The sliding component 11 is slidably connected to the inner wall of the slide rail 13 through a moving part; The moving part includes a sliding block 111 slidably connected to the inner wall of the slide rail 13. A first sliding tube 112 is fixedly connected to the side wall of the sliding block 111. A second sliding tube 113 is slidably connected to the inner wall of the first sliding tube 112. The inner wall of the first sliding tube 112 is fixedly connected to the outer wall of the snap connection end 16; A limiting component 12. The limiting component 12 is fixedly connected to the inner wall of the slide rail 13 through a snap-fastening part; The snap-fastening part includes a fixed rod 121 fixedly connected to the inner wall of the slide rail 13. A first clamping groove 122 is formed in the side wall of the fixed rod 121; Before use, first fix the electric box 18 on the wall. When the external pulling force is transmitted to the clamping end 16 through the output wire 17, the clamping end 16 will drive the sliding tube one 112 and the sliding block 111 to slide downward along the slide rail 13; Among them, the depth of the bottom slot one 122 is greater than that of the top.

[0024] The sliding mechanism 2 includes: The auxiliary component 21, and the auxiliary component 21 is slidably connected to the side wall of the sliding tube two 113 through a sliding member; The sliding member includes a transverse chute 211 opened on the side wall of the sliding tube two 113. A triangular slide plate 212 is slidably connected to the inner wall of the transverse chute 211. A second spring 213 is fixedly connected to the top of the triangular slide plate 212. A first slide plate 214 is slidably connected to the inner wall of the transverse chute 211; The linkage component 22, and the linkage component 22 is fixedly connected to the side wall of the first slide plate 214 through a driving member; The driving member includes a toothed ring 221 fixedly connected to the side wall of the first slide plate 214. A fixing plate 222 is fixedly connected to the side wall of the slide rail 13. A toothed column 223 is rotatably connected to the side wall of the fixing plate 222; Among them, the outer wall of the toothed column 223 is meshed with the outer wall of the toothed ring 221. When the toothed column 223 rotates, the toothed ring 221 will force the sliding tube two 113 to move up and down along the inner wall of the sliding block 111.

[0025] The pressure mechanism 3 includes: The driving component 31, and the driving component 31 is fixedly connected to the side wall of the sliding block 111 through a pressing member; The pressing member includes a second slide plate 311 fixedly connected to the side wall of the sliding block 111. A toothed rod 312 is fixedly connected to the side wall of the second slide plate 311; The buckle component 32, and the buckle component 32 is fixedly connected to the top of the fixing plate 222 through a one-way member; The one-way member includes a sliding square tube 321 fixedly connected to the top of the fixing plate 222. An inclined plane slider 322 is slidably connected to the inner wall of the sliding square tube 321. A third spring 323 is fixedly connected to the side wall of the inclined plane slider 322; Among them, when the sliding block 111 slides up and down along the inner wall of the slide rail 13, at this time, the second slide plate 311 drives the linkage component 22 to rotate through the toothed rod 312. The rotating force will be transmitted to the toothed ring 221 through the toothed column 223, forcing the toothed ring 221 to drive the sliding tube two 113 to move up and down.

[0026] Example two, please refer to Figures 2-10, the present invention is a connection structure for a charging pile cable joint. Based on Example 1, the sliding assembly 11 includes a first spring 114 fixedly connected to the top of the sliding block 111. A fixed block 115 is fixedly connected to the inner wall of the slide rail 13. The top of the first spring 114 is fixedly connected to the bottom of the flexible wire 15; Among them, when the output wire 17 is subjected to a tensile force, the output wire 17 drives the first sliding tube 112 and the sliding block 111 to slide downward through the clamping end 16. At this time, the first spring 114 will deform and store potential energy.

[0027] The limiting assembly 12 includes a spring slider 123 slidably connected to the side wall of the sliding block 111. An arc surface 124 is provided at the top of the spring slider 123, and an inclined surface 125 is provided at the bottom of the spring slider 123; The width of the arc surface 124 is greater than the width of all the first clamping grooves 122, and the width of the lowermost first clamping groove 122 is greater than the width of the inclined surface 125; Among them, when the spring slider 123 slides downward, the shallower first clamping groove 122 will contact the inclined surface 125 and force the spring of the spring slider 123 to contract and deform. When the spring slider 123 reaches the bottommost position, the bottom plane of the spring slider 123 will contact the plane of the deeper first clamping groove 122 and limit the further downward movement of the sliding block 111; During the downward sliding of the sliding block 111, the spring slider 123 moves outward under the push of its own spring and forces the end of the spring slider 123 to enter the inner wall of the first clamping groove 122. Before the spring slider 123 reaches the bottommost position, as Figure 5 shown, it will present the topmost state. At this time, the inclined surface of the inclined surface 125 still contacts the edge of the first clamping groove 122. When the sliding block 111 moves downward, the spring slider 123 will slide and contract. When the spring slider 123 reaches the bottommost position, after the spring slider 123 enters the inner wall of the deeper first clamping groove 122, at this time, the bottom plane of the spring slider 123 will contact the plane of the first clamping groove 122 to limit the further downward movement of the sliding block 111. At this time, the external tensile force will be transmitted to the fixed rod 121 and the slide rail 13 through the sliding block 111 and the spring slider 123. Through the application of the above components, when an external tensile force appears, the force on the joint position of the clamping end 16 and the flexible wire 15 is reduced.

[0028] The auxiliary assembly 21 includes a convex block 215 fixedly connected to the inner wall of the first sliding plate 214; Among them, when the tooth ring 221 moves horizontally left and right, the sliding plate one 214 will drive the convex block 215 to move horizontally synchronously. During this process, the spring two 213 will force the triangular slide plate 212 to always be in the lowest position. When the convex block 215 moves, affected by the arc surface of the triangular slide plate 212, the initial sliding resistance is relatively large. When the convex block 215 crosses the lowest point of the triangular slide plate 212, at this time, the triangular slide plate 212 will squeeze the plane of the convex block 215, causing the convex block 215 and the sliding plate one 214 to quickly complete the horizontal movement; When the sliding block 111 moves downward, the spring one 114 will deform and accumulate mechanical power. After the external pulling force disappears, the spring one 114 will drive the sliding block 111 to reset. During this process, after the arc surface 124 contacts the edge of the slot one 122, the spring slider 123 will contract, and the sliding block 111 will be pulled by the spring one 114 to reset.

[0029] The linkage assembly 22 includes a gear one 224 rotatably connected to the side wall of the fixed plate 222, and the outer wall of the gear one 224 is meshed and connected to the outer wall of the tooth column 223; Among them, when the tooth bar 312 moves downward, the tooth bar 312 drives the gear one 224 to rotate through the drive assembly 31, and the gear one 224 drives the tooth column 223 to rotate; During the process of the tooth column 223 driving the tooth ring 221 to move up and down, when reaching the upper and lower curved arc positions of the tooth ring 221, the rotation of the tooth column 223 will force the tooth ring 221 and the sliding plate one 214 to move horizontally along the inner wall of the horizontal chute 211. During the horizontal movement of the sliding plate one 214, the convex block 215 will squeeze the triangular slide plate 212 to move up and down along the inner wall of the horizontal chute 211. As Figure 8 shown, the spring two 213 will force the triangular slide plate 212 to always be in the lowest position. When the convex block 215 moves, affected by the arc surface of the triangular slide plate 212, the initial sliding resistance is relatively large. When the convex block 215 crosses the lowest point of the triangular slide plate 212, at this time, the triangular slide plate 212 will squeeze the plane of the convex block 215, causing the convex block 215 and the sliding plate one 214 to quickly complete the horizontal movement, increasing the contact force between the inner wall of the tooth ring 221 and the tooth column 223. Through the application of the above components, the contact force between the tooth column 223 and the tooth ring 221 is ensured, and the phenomenon of tooth loosening is avoided.

[0030] The drive assembly 31 includes a thorn gear 313 fixedly connected to the outer wall of the gear one 224; Among them, the outer wall of the thorn gear 313 is meshed and connected to the outer wall of the tooth bar 312. When the tooth bar 312 moves downward, the thorn gear 313 will rotate. When the sliding plate two 311 moves upward, the inner inclined surface of the thorn gear 313 will contact the plane of the sliding plate two 311, and the thorn gear 313 will no longer rotate; Taking advantage of the characteristic that the sliding block 111 slides downward under tension, a sliding mechanism 2 and a pressure mechanism 3 are provided inside the device. When the sliding block 111 moves downward, the second sliding plate 311 will drive the rack 312 to move downward synchronously. As Figure 6 shown, at this time, the rack 312 will drive the barbed gear 313 to rotate clockwise. The barbed gear 313 drives the tooth column 223 to rotate counterclockwise through the first gear 224. The rotating tooth column 223 will drive the tooth ring 221 and the second sliding tube 113 to move up and down along the inner wall of the first sliding tube 112 for a certain distance. Through the application of the above components, it is ensured that after each pull on the output line 17, the tooth ring 221 will drive the second sliding tube 113 to move a small distance, changing the contact position between the inner wall of the second sliding tube 113 and the outer wall of the output line 17, and preventing the output line 17 from being bent multiple times at a single position, resulting in damage to the outer wall of the output line 17.

[0031] The buckle assembly 32 includes a second card slot 324 opened on the side wall of the first gear 224; Among them, when the rack 312 moves downward, the first gear 224 will rotate clockwise. At this time, the inclined surface of the inclined surface slider 322 contacts the plane of the second card slot 324. When the rack 312 moves upward, the plane of the inclined surface slider 322 will contact the plane of the second card slot 324, restricting the rotation of the second card slot 324; Taking advantage of the characteristic that the barbed gear 313 drives the first gear 224 to rotate, a buckle assembly 32 is provided inside the device. When the rack 312 moves downward, the first gear 224 will rotate clockwise. At this time, the inclined surface of the inclined surface slider 322 contacts the plane of the second card slot 324. When the rack 312 moves upward, the plane of the inclined surface slider 322 will contact the plane of the second card slot 324, restricting the rotation of the second card slot 324. Through the application of the above components, when the rack 312 moves upward, it is prevented that the first gear 224 rotates correspondingly, causing the second sliding tube 113 to reciprocate under the external tension.

[0032] A specific application of this embodiment is as follows: Before the present invention is used, the electric box 18 is first fixed on the wall. When the external tension is transmitted to the clamping end 16 through the output line 17, the clamping end 16 will drive the first sliding tube 112 and the sliding block 111 to slide downward along the slide rail 13; During the downward sliding of the sliding block 111, the spring slider 123 moves outward under the push of its own spring and forces the end of the spring slider 123 to enter the inner wall of the first card slot 122. Before the spring slider 123 reaches the bottommost position, as Figure 5As shown, the topmost state will be presented. At this time, the inclined plane of the inclined plane 125 still contacts the edge of the first clamping groove 122. When the sliding block 111 moves downward, the spring slider 123 will slide and contract. When the spring slider 123 reaches the bottommost position, after the spring slider 123 enters the inner wall of the deeper first clamping groove 122, the bottom plane of the spring slider 123 will contact the plane of the first clamping groove 122, restricting the continued downward movement of the sliding block 111. At this time, the external pulling force will be transmitted to the fixed rod 121 and the slide rail 13 through the sliding block 111 and the spring slider 123. Through the application of the above components, when an external pulling force appears, the force on the joint position of the clamping end 16 and the flexible wire 15 is reduced; When the sliding block 111 moves downward, the first spring 114 will deform and accumulate mechanical power. After the external pulling force disappears, the first spring 114 will drive the sliding block 111 to reset. In this process, after the arc surface 124 contacts the edge of the first clamping groove 122, the spring slider 123 will contract, and the sliding block 111 will be pulled back by the first spring 114; Utilizing the characteristic that the sliding block 111 slides downward under the pulling force, a sliding mechanism 2 and a pressure mechanism 3 are arranged inside the device. When the sliding block 111 moves downward, the second sliding plate 311 will drive the toothed rod 312 to move downward synchronously, as Figure 6 shown. At this time, the toothed rod 312 will drive the thorn gear 313 to rotate clockwise. The thorn gear 313 drives the toothed column 223 to rotate counterclockwise through the first gear 224. The rotating toothed column 223 will drive the toothed ring 221 and the second sliding tube 113 to move up and down along the inner wall of the first sliding tube 112 for a certain distance. Through the application of the above components, it is ensured that after each pulling of the output wire 17, the toothed ring 221 will drive the second sliding tube 113 to move a small distance, changing the contact position between the inner wall of the second sliding tube 113 and the outer wall of the output wire 17, and preventing the outer wall of the output wire 17 from being damaged due to multiple bends at a single position.

[0033] Among them, during the process of the toothed column 223 driving the toothed ring 221 to move up and down, when reaching the upper and lower arc positions of the toothed ring 221, the rotation of the toothed column 223 will force the toothed ring 221 and the first sliding plate 214 to move horizontally along the inner wall of the horizontal sliding groove 211. During the horizontal movement of the first sliding plate 214, the convex block 215 will squeeze the triangular sliding plate 212 to move up and down along the inner wall of the horizontal sliding groove 211, as Figure 8As shown, the second spring 213 will force the triangular slide plate 212 to always be in the lowest position. When the bump 215 moves, affected by the arc surface of the triangular slide plate 212, the initial sliding resistance is relatively large. When the bump 215 crosses the lowest point of the triangular slide plate 212, at this time, the triangular slide plate 212 will squeeze the plane of the bump 215, causing the bump 215 and the first slide plate 214 to quickly complete the lateral movement, increasing the contact force between the inner wall of the toothed ring 221 and the toothed column 223. Through the application of the above components, the contact force between the toothed column 223 and the toothed ring 221 is ensured, and the phenomenon of tooth looseness is avoided.

[0034] Taking advantage of the characteristic that the above-mentioned thorny gear 313 drives the first gear 224 to rotate, a buckle assembly 32 is provided inside the device. When the toothed rod 312 moves downward, the first gear 224 will rotate clockwise. At this time, the inclined surface of the inclined surface slider 322 contacts the plane of the second card slot 324. When the toothed rod 312 moves upward, the plane of the inclined surface slider 322 will contact the plane of the second card slot 324, restricting the rotation of the second card slot 324. Through the application of the above components, when the toothed rod 312 moves upward, it is prevented that the first gear 224 rotates correspondingly, causing the second sliding tube 113 to reciprocate under the external tensile force.
