Description

Technical Field

[0001] The present invention relates to the technical field of cable reels, and particularly relates to a cable reel with adjustable capacity. Background Art

[0002] Electric wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electrical and magnetic energy. In a broad sense, electric wires and cables are also simply referred to as cables. In a narrow sense, a cable refers to an insulated cable, which can be defined as a collective body composed of the following parts: one or more insulated wire cores, and their respective possible coating layers, total protective layer, and outer protective layer. A cable may also have additional non-insulated conductors. Usually, a pay-off reel is required to store or retrieve the cable.

[0003] A cable reel is a special type of reel for electric wires and cables. Cable reels are divided into two types: large and small. The diameter of a large cable reel exceeds 1 meter, and some even reach more than 5 meters. The typical representatives are mostly wooden large-scale transportation and logistics wire reels. The diameter of a small cable reel is only 30 cm - 100 cm. The typical representatives are cable reels made of ABS flame-retardant materials and high-temperature-resistant materials. Cable reels are often used during construction.

[0004] In the actual operation of personnel using a cable pay-off and take-up reel, a reel with capacity adjustment can be used to adapt to cables of different sizes. The existing cable reels generally directly wind the cable around the reel body. The cable may be wound loosely and not tightly, and the loose cables are prone to entanglement with each other, affecting the working efficiency during use. At the same time, the end of the cable will be in a natural drooping state. When the reel is not in use, the cable interface cannot be protected, easily resulting in accidental injuries or equipment damage. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that the cable is prone to looseness after being wound in the prior art, and a cable reel with adjustable capacity is proposed.

[0006] To achieve the above purpose, the present invention adopts the following technical solution: A cable reel with adjustable capacity, including a support frame. The bottom of the support frame is fixedly connected with a base. The top of the base is fixedly connected with a first connecting plate, and the top of the first connecting plate is fixedly connected with a fixing plate. One end of the fixing plate away from the first connecting plate is fixedly connected with a second connecting plate; An extrusion mechanism is arranged on the top of the base to compact and level the cable when the cable is wound; A cleaning mechanism is arranged on the top of the second connecting plate to clean the surface of the cable when the cable is paid off and wound; A locking mechanism is arranged inside the second connecting plate to automatically lock the cable when the cable winding is completed.

[0007] Furthermore, the extrusion mechanism includes a bottom plate, and a second spring is fixedly connected to the top of the bottom plate. One end of the second spring away from the bottom plate is fixedly connected to an extrusion plate. A T-shaped groove is formed in the top of the extrusion plate. First bumps are fixedly connected to both side walls of the extrusion plate. A T-shaped block is slidably connected inside the T-shaped groove. The first rotating plate and the second rotating plate are hinged to the top of the bottom plate through a torsion spring. A clamping strip is fixedly connected to the side of the first rotating plate facing the extrusion plate. A handle is fixedly connected to the side of the first rotating plate away from the clamping strip.

A fourth spring is fixedly connected between the two extrusion rods. The bottom of the bottom plate is fixedly connected to the top of the second connecting plate.

[0009] Furthermore, the cleaning mechanism includes a connecting seat. A first rotating shaft is rotatably connected to the side wall of the connecting seat. A connecting block is fixedly connected to the outer wall of the first rotating shaft. A second rotating shaft is fixedly connected to the top of the connecting block. One end of the second rotating shaft away from the connecting block is rotatably connected to a third connecting plate. A chute is formed in the top of the third connecting plate. Two cleaning blocks are slidably connected to the inner wall of the chute. Fifth springs are fixedly connected to the mutually away ends of the two cleaning blocks. One end of the fifth spring away from the cleaning block is fixedly connected to the inner wall of the chute. A guiding ring is fixedly connected to the bottom of the third connecting plate. A through groove is formed through the bottom of the cleaning block, and the through groove corresponds to the inner wall of the guiding ring. A connecting groove is formed through the side wall of the cleaning block.

[0010] Furthermore, the locking mechanism includes two resisting rods and an inclined rod. The bottoms of the two resisting rods are fixedly connected together with a movable plate. A tension spring is fixedly connected to the top of the movable plate. One end of the tension spring away from the movable plate is fixedly connected to the bottom of the second connecting plate. A sliding plate is fixedly connected to the end of the inclined rod. Locking clips are fixedly connected to both ends of the sliding plate.

[0011] Furthermore, the outer wall of the abutting rod is slidably connected through the inside of the second connecting plate. The outer wall of the abutting rod corresponds to the inner wall of the guiding ring. The outer wall of the abutting rod is slidably connected to the inner wall of the through groove. The end of the abutting rod away from the movable plate corresponds to the inclined surface at the end of the inclined rod. The side wall of the sliding plate is slidably connected to the inner wall of the connecting groove. The side wall of the locking clip is slidably connected to the side wall of the cleaning block.

[0012] Furthermore, a sliding rod is slidably connected through the inside of the first connecting plate. The end of the sliding rod away from the second rotating plate is fixedly connected with a clamping block. A limiting block is fixedly connected to the outer wall of the sliding rod. A first spring is fixedly connected to the side wall of the limiting block. The end of the first spring away from the limiting block is fixedly connected to the inside of the first connecting plate.

[0013] Furthermore, a first side plate is rotatably connected to the side wall of the support frame. A sliding cover is fixedly connected to the side wall of the first side plate. A disk body is slidably connected to the inner wall of the sliding cover. A second side plate is fixedly connected to the side wall of the disk body. A rocker is rotatably connected to the side wall of the second side plate.

[0014] Furthermore, a threaded rod is rotatably connected through the side wall of the first side plate. A knob is fixedly connected to the end of the threaded rod. A threaded hole matching the threaded rod is provided at one end of the disk body.

[0015] Compared with the prior art, the above solution has the following beneficial effects: 1. By controlling the rocker to drive the second side plate to rotate, then the disk body and the sliding cover will drive the first side plate to rotate, realizing the winding work of the cable. During this process, the elastic force of the third spring drives the extrusion rod to slide along the opposite sides of the first side plate and the second side plate, so that the outer walls of the two extrusion rods are squeezed and attached to the wound cable. Through the extrusion of the cable by the extrusion rod, the cable can be tightly attached to the outer walls of the sliding cover and the disk body, realizing the pressing effect on the cable, making the cable winding more compact and not being too loose.

[0016] 2. During the process of cable winding, before the cable is wound by the sliding cover and the disk body, it will pass through the gap between the two cleaning blocks. The cleaning blocks can scrape off the dust and dirt attached to the outer wall surface of the cable, ensuring the cleanliness of the cable during winding, thereby improving the neatness of the cable in subsequent winding. At the same time, through scraping and cleaning, the outer wall of the cable can be effectively protected, reducing wear and corrosion, and thus extending the overall service life of the cable.

[0017] 3. When the cable winding is completed, during the process, the extrusion rod drives the extrusion plate to extrude downward, causing the second rotating plate to flip outward. After that, the clamping block will disengage from the position of the movable plate, and then the inner wall of the locking clip will be extruded and fitted to the outer wall of the cable. By squeezing the cable with multiple locking clips, the function of clamping the end of the cable when the winding is completed is realized, and the function of protecting the cable end interface is realized. Compared with the traditional wire reel that cannot fix the end of the cable, which makes the cable too loose and scattered, resulting in accidental injuries or equipment damage, it saves the time and energy of the staff and improves the work efficiency.

[0018] 4. By manually controlling the first side plate for limiting, then the knob drives the threaded rod to rotate synchronously, causing the disc body to slide along the inner wall of the sliding cover. At this time, the distance between the first side plate and the second side plate becomes larger, thereby expanding the storage capacity of the cable. By controlling the knob to rotate in the reverse direction, the storage capacity of the cable is reduced, realizing the effect of adjustable storage capacity of the cable. The cable reel can freely match cables of different sizes, improving the practicality of the reel. Brief Description of the Drawings

In addition, the terms "first" and "second" are only used to distinguish an entity or operation from another entity or operation, and do not require or imply any actual relationship, order or relative importance between these entities or operations.

[0023] Embodiment 1, please refer to Figure 1 - Figure 2 , a cable reel with adjustable capacity, including a support frame 1, the bottom of the support frame 1 is fixedly connected with a base 2, the top of the base 2 is fixedly connected with a first connecting plate 4, and the top of the first connecting plate 4 is fixedly connected with a fixing plate 5, and one end of the fixing plate 5 away from the first connecting plate 4 is fixedly connected with a second connecting plate 6; Further, a first side plate 13 is rotatably connected to the side wall of the support frame 1, and a sliding cover 14 is fixedly connected to the side wall of the first side plate 13. A disk body 15 is slidably connected to the inner wall of the sliding cover 14, and a second side plate 16 is fixedly connected to the side wall of the disk body 15. A rocker 17 is rotatably connected to the side wall of the second side plate 16. A threaded rod 18 is rotatably connected through the side wall of the first side plate 13, and a knob 19 is fixedly connected to the end of the threaded rod 18. A threaded hole matching the threaded rod 18 is formed at one end of the disk body 15; An extrusion mechanism 3 is arranged on the top of the base 2 to compact and flatten the cable when the cable is wound; The extrusion mechanism 3 includes a bottom plate 301, and a second spring 302 is fixedly connected to the top of the bottom plate 301. One end of the second spring 302 away from the bottom plate 301 is fixedly connected to an extrusion plate 303. A T-shaped groove 304 is formed in the top of the extrusion plate 303. First convex blocks 305 are fixedly connected to both side walls of the extrusion plate 303. A T-shaped block 306 is slidably connected to the inside of the T-shaped groove 304. A first rotating plate 307 and a second rotating plate 310 are hinged to the top of the bottom plate 301 through torsion springs. A clamping strip 308 is fixedly connected to the side of the first rotating plate 307 facing the extrusion plate 303. A handle 309 is fixedly connected to the side of the first rotating plate 307 away from the clamping strip 308. A second convex block 311 is fixedly connected to one end of the second rotating plate 310 facing the extrusion plate 303. Fixed blocks 312 are fixedly connected to the mutually remote ends of the T-shaped block 306 and the extrusion plate 303. A slider 313 is slidably connected through the inside of the fixed block 312. A third spring 314 is fixedly connected to the bottom of the slider 313, and one end of the third spring 314 away from the slider 313 is fixedly connected to the inner wall of the fixed block 312. Extrusion rods 315 are fixedly connected to the tops of the two sliders 313. The mutually approaching ends of the two extrusion rods 315 are inserted into each other. A fourth spring 316 is fixedly connected between the two extrusion rods 315. The bottom of the bottom plate 301 is fixedly connected to the top of the second connecting plate 6; More specifically, the service environment of the cable on the cable reel has a great impact on its lifespan. For example, in a harsh industrial environment, the cable may be more vulnerable to corrosion, wear and other damages, and requires frequent inspections and maintenance. When problems such as aging and breakage occur, it needs to be replaced. The cable reel can adjust its capacity according to the new cable size. First, manually control the first side plate 13 for limiting, then manually rotate the knob 19. Then, the knob 19 will drive the threaded rod 18 to rotate synchronously. Since the disc body 15 is connected to the threaded rod 18 by threads, the rotation of the threaded rod 18 will cause the disc body 15 to move in a direction away from each other. Then, the disc body 15 will slide along the inner wall of the sliding cover 14. The disc body 15 will drive the second side plate 16 and the rocker 17 to move synchronously. At this time, the distance between the first side plate 13 and the second side plate 16 becomes larger, thereby expanding the cable capacity that can be stored. By controlling the knob 19 to rotate in the reverse direction, the cable capacity that can be stored is reduced, achieving the effect of adjustable cable storage capacity, enabling the cable reel to freely match cables of different sizes, and improving the practicality of the reel.

[0024] Embodiment 2. Please refer to Figure 2 - Figure 5 , on the basis of Embodiment 1, in this embodiment, an extrusion mechanism 3 is provided on the top of the base 2 to compact and smooth the cable when winding the cable; The extrusion mechanism 3 includes a bottom plate 301, and a second spring 302 is fixedly connected to the top of the bottom plate 301. One end of the second spring 302 away from the bottom plate 301 is fixedly connected to an extrusion plate 303. A T-shaped groove 304 is opened at the top of the extrusion plate 303. First convex blocks 305 are fixedly connected to both side walls of the extrusion plate 303. And a T-shaped block 306 is slidably connected inside the T-shaped groove 304. The top of the bottom plate 301 is hinged with a first rotating plate 307 and a second rotating plate 310 through a torsion spring. A clamping bar 308 is fixedly connected to the side of the first rotating plate 307 facing the extrusion plate 303. A handle 309 is fixedly connected to the side of the first rotating plate 307 away from the clamping bar 308. A second convex block 311 is fixedly connected to one end of the second rotating plate 310 facing the extrusion plate 303. Fixing blocks 312 are fixedly connected to the mutually remote ends of the T-shaped block 306 and the extrusion plate 303. And a slider 313 is slidably penetrated inside the fixing block 312. A third spring 314 is fixedly connected to the bottom of the slider 313. And one end of the third spring 314 away from the slider 313 is fixedly connected to the inner wall of the fixing block 312. Extrusion rods 315 are fixedly connected to the tops of the two sliders 313. The mutually approaching ends of the two extrusion rods 315 are inserted into each other. A fourth spring 316 is fixedly connected between the two extrusion rods 315. The bottom of the bottom plate 301 is fixedly connected to the top of the second connecting plate 6; More specifically, when the cable reel is used up and being wound up, the second side plate 16 is driven to rotate by controlling the rocker 17. Then, the second side plate 16 drives the first side plate 13 to rotate synchronously through the disc body 15 and the sliding cover 14, realizing the winding work of the cable. During this process, the elastic force of the third spring 314 drives the slider 313 to slide upward along the inner wall of the fixed block 312. Then, the two fixed blocks 312 drive the corresponding extrusion rods 315 to slide fittingly along the opposite sides of the first side plate 13 and the second side plate 16, so that the outer walls of the two extrusion rods 315 are extruded and fitted on the wound cable. Through the extrusion of the extrusion rod 315 on the cable, the cable can be tightly attached to the outer walls of the sliding cover 14 and the disc body 15, realizing the pressing effect on the cable; After that, when the outer walls of the sliding cover 14 and the disc body 15 become larger in diameter due to the winding of the cable, the extrusion rod 315 extrudes the fixed block 312 through the slider 313, compressing the third spring 314 again. Thus, when the winding diameter of the cable becomes larger, the extrusion rod 315 can always extrude the cable. After that, when the pressure on the third spring 314 is too large, then the fixed block 312 drives the extrusion plate 303 to apply downward pressure, compressing the second spring 302. Then, the extrusion plate 303 drives the first convex block 305 to extrude the latch 308. Since the extrusion surface of the latch 308 is an inclined surface, the first rotating plate 307 will rotate around the torsion spring connected to the bottom plate 301 as the axis. Then, after the latch 308 is driven to flip outward, at this time, the extrusion plate 303 will apply downward pressure. When the first convex block 305 passes over the corresponding latch 308, at this time, the first rotating plate 307 will reset and flip through the torsion force of the torsion spring, and then make the first convex block 305 stuck between the two latches 308, thus offsetting the elastic force applied by the second spring 302 to the extrusion plate 303, so as to realize that an appropriate distance is maintained between the third spring 314 and the cable, avoiding the situation that the extrusion force applied by the extrusion rod 315 to the cable is too large and causing cable damage; When adjusting the capacity of the reel, since the fourth spring 316 between the two extrusion rods 315 is always in a compressed state, while the second side plate 16 moves away from the first side plate 13, the fourth spring 316 drives the two extrusion rods 315 to move away from each other, so that the ends of the two extrusion rods 315 moving away from each other always press on the opposite sides of the first side plate 13 and the second side plate 16, ensuring the practicability of the extrusion rod 315 during the winding process. At the same time, during the process of the two extrusion rods 315 moving away from each other, the T-shaped block 306 is driven to slide along the inner wall of the T-shaped groove 304 through the third spring 314, thus ensuring the stability of the two extrusion rods 315 during the movement.

[0025] Example three, please refer to Figure 6 - Figure 8, on the basis of the second embodiment, in this embodiment, a cleaning mechanism 7 is provided on the top of the second connecting plate 6 to clean the surface of the cable when the cable is wound and unwound; Further, the cleaning mechanism 7 includes a connecting seat 701, and a first rotating shaft 702 is rotatably connected to the side wall of the connecting seat 701. A connecting block 703 is fixedly connected to the outer wall of the first rotating shaft 702, and a second rotating shaft 704 is fixedly connected to the top of the connecting block 703. One end of the second rotating shaft 704 away from the connecting block 703 is rotatably connected to a third connecting plate 705, and a chute 706 is provided on the top of the third connecting plate 705. Two cleaning blocks 707 are slidably connected to the inner wall of the chute 706. One ends of the two cleaning blocks 707 away from each other are fixedly connected to a fifth spring 708, and one end of the fifth spring 708 away from the cleaning block 707 is fixedly connected to the inner wall of the chute 706. A guiding ring 709 is fixedly connected to the bottom of the third connecting plate 705. A through groove 710 is formed through the bottom of the cleaning block 707, and the through groove 710 corresponds to the inner wall of the guiding ring 709. A connecting groove 711 is formed through the side wall of the cleaning block 707; More specifically, during the process of cable winding, before the cable is wound by the sliding cover 14 and the disc body 15, it will pass through the gap between the two cleaning blocks 707. Since the inner wall of the gap between the two cleaning blocks 707 is provided with cleaning cotton, when the cable passes through its interior, the cleaning block 707 can scrape off the dust and dirt attached to the outer wall surface of the cable, ensuring the cleanliness of the cable during winding, thereby improving the neatness of the cable during subsequent winding; By sliding the two cleaning blocks 707 on the inner wall of the chute 706 at the same time, the positions of the two cleaning blocks 707 are kept consistent. At the same time, the elastic force of the chute 706 will squeeze the corresponding cleaning block 707, causing the two cleaning blocks 707 to displace in the direction towards each other, so as to ensure that the inner walls of the two cleaning blocks 707 are always attached to the outer wall of the cable, ensuring the stability of the subsequent cleaning work; During the process of cable winding, the position of the cable on the wire reel will change, and its diameter will also gradually increase. By rotating the third connecting plate 705 in the horizontal direction at the end of the second rotating shaft 704, and at the same time, the connecting block 703 rotates in the vertical direction on the inner wall of the connecting seat 701 through the first rotating shaft 702, the inner wall of the cleaning block 707 can rotate freely, and thus is driven by the cable, realizing that the cleaning block 707 always faces the position where the cable is wound on the wire reel. While ensuring that the cleaning block 707 cleans the cable, changing the position of the cleaning block 707 will not cause the cable to bend, thereby avoiding damage to the cable during the cleaning process, and at the same time being able to provide a role of straightening and guiding the cable.

[0026] Embodiment Four, please refer to Figure 3 and Figure 7, on the basis of Embodiment 3, in this embodiment, a locking mechanism 8 is provided inside the second connecting plate 6 to automatically lock the cable when the cable winding is completed. A sliding rod 9 is slidably connected through the inside of the first connecting plate 4, and a clamping block 10 is fixedly connected to one end of the sliding rod 9 away from the second rotating plate 310. A limiting block 11 is fixedly connected to the outer wall of the sliding rod 9, and a first spring 12 is fixedly connected to the side wall of the limiting block 11. One end of the first spring 12 away from the limiting block 11 is fixedly connected inside the first connecting plate 4; Further, the locking mechanism 8 includes two abutting rods 801 and an inclined rod 804. The bottoms of the two abutting rods 801 are fixedly connected together with a movable plate 802, and a tension spring 803 is fixedly connected to the top of the movable plate 802. One end of the tension spring 803 away from the movable plate 802 is fixedly connected to the bottom of the second connecting plate 6. The end of the inclined rod 804 is fixedly connected to a sliding plate 805, and locking clips 806 are fixedly connected to both ends of the sliding plate 805. The outer walls of the abutting rods 801 are slidably connected through the inside of the second connecting plate 6. The outer walls of the abutting rods 801 correspond to the inner walls of the guiding rings 709. The outer walls of the abutting rods 801 are slidably connected to the inner walls of the through grooves 710. One end of the abutting rod 801 away from the movable plate 802 corresponds to the inclined surface at the end of the inclined rod 804. The side wall of the sliding plate 805 is slidably connected to the inner wall of the connecting groove 711. The side wall of the locking clip 806 is slidably connected to the side wall of the cleaning block 707; More specifically, when the cable winding is completed, at this time, the winding diameters of the sliding cover 14 and the disk body 15 will reach the limit. During the process, the extrusion rod 315 will drive the extrusion plate 303 to squeeze downward. Then, the first convex block 305 will be stuck below the bottommost clamping strip 308. Then, the first convex block 305 on the other side of the extrusion plate 303 will squeeze the second convex block 311, so that the second rotating plate 310 will turn outward. During the turning process of the second rotating plate 310, the end of the sliding rod 9 will be squeezed, causing the sliding rod 9 to slide along the inside of the first connecting plate 4. At the same time, the sliding rod 9 will drive the clamping block 10 to move synchronously; After that, the clamping block 10 will disengage from the clamping position of the movable plate 802. At this time, the tensile force of the tension spring 803 will drive the movable plate 802 to displace upward. At the same time, the movable plate 802 will drive the abutting rod 801 to slide upward along the inside of the second connecting plate 6. Then, the upper end of the abutting rod 801 will slide along the inner wall of the guiding ring 709 to the inner wall of the through groove 710. After passing through, it will squeeze the end slope of the inclined rod 804, causing the inclined rod 804 to drive the sliding plate 805 to slide along the inner wall of the connecting groove 711. At the same time, the locking clip 806 will displace synchronously with the sliding plate 805. After that, the inner wall of the locking clip 806 will squeeze and fit against the outer wall of the cable. By squeezing the cable with multiple locking clips 806, when the winding is completed, the function of clamping the end of the cable is realized, and the function of protecting the end interface of the cable is realized. Compared with the traditional wire reel that cannot fix the end of the cable, which makes the cable too loose and scattered, resulting in accidental injuries or equipment damage, it saves the time and energy of the staff and improves the work efficiency; After that, when it is needed to be used again, pull the handle 309 to flip the first rotating plate 307. Then, the first convex block 305 is no longer clamped by the clamping strip 308. Then, the second spring 302 will return to its elastic position, and then drive the pressing plate 303 to return. After that, pull the movable plate 802 downward. Then, the movable plate 802 will squeeze the top slope of the clamping block 10. Then, the sliding of the sliding rod 9 will drive the limiting block 11 to compress the first spring 12. After that, the movable plate 802 will cross the slope of the clamping block 10. At this time, the sliding rod 9 will return to its position by the elastic force of the first spring 12, thus realizing the limit of the clamping block 10 to the movable plate 802 and completing the reset.

[0027] The working principle of the present invention is: manually control the first side plate 13 for limiting, then manually rotate the knob 19. Then, the knob 19 will drive the threaded rod 18 to rotate synchronously. Since the disc body 15 is connected to the threaded rod 18 by threads, the rotation of the threaded rod 18 will cause the disc body 15 to move in a direction away from each other. Then, the disc body 15 will slide along the inner wall of the sliding cover 14. The disc body 15 will drive the second side plate 16 and the rocker 17 to move synchronously. At this time, the distance between the first side plate 13 and the second side plate 16 becomes larger, thus expanding the cable storage capacity. By controlling the reverse rotation of the knob 19, the cable storage capacity is reduced, realizing the effect of adjustable cable storage capacity; When the cable reel is used up and being wound up, the second side plate 16 is driven to rotate by controlling the rocker 17. Then, the second side plate 16 drives the first side plate 13 to rotate synchronously through the disc body 15 and the sliding cover 14, realizing the winding work of the cable. During this process, the elastic force of the third spring 314 drives the slider 313 to slide upward along the inner wall of the fixed block 312. Then, the two fixed blocks 312 drive the corresponding extrusion rods 315 to slide along the opposite sides of the first side plate 13 and the second side plate 16 in a fitting manner, so that the outer walls of the two extrusion rods 315 are extruded and fitted on the wound cable. Through the extrusion of the cable by the extrusion rods 315, the cable can be tightly attached to the outer walls of the sliding cover 14 and the disc body 15, achieving the pressing effect on the cable; During the process of winding the cable, the cable passes through the gap between the two cleaning blocks 707 before being wound by the sliding cover 14 and the disc body 15. Since the inner wall of the gap between the two cleaning blocks 707 is provided with cleaning cotton, when the cable passes through its interior, the cleaning blocks 707 can scrape off the dust and dirt attached to the outer wall surface of the cable, ensuring the cleanliness of the cable during winding; When the cable winding is completed, at this time, the winding diameters of the sliding cover 14 and the disc body 15 reach the limit. During the process, the extrusion rod 315 drives the extrusion plate 303 to squeeze downward. Then, the first convex block 305 is stuck below the bottommost catch bar 308. Then, the first convex block 305 on the other side of the extrusion plate 303 squeezes the second convex block 311, so that the second rotating plate 310 flips outward, and the sliding rod 9 slides along the inside of the first connecting plate 4. After that, the catch block 10 disengages from the position of the movable plate 802. At this time, the tensile force of the tension spring 803 drives the movable plate 802 to displace upward. Then, the upper end of the abutting rod 801 slides along the inner wall of the guiding ring 709 to the inner wall of the through groove 710. After passing through, it squeezes the end slope of the inclined rod 804, so that the inclined rod 804 drives the sliding plate 805 to slide along the inner wall of the connecting groove 711. At the same time, the locking clip 806 displaces synchronously with the sliding plate 805. After that, the inner wall of the locking clip 806 is extruded and fitted on the outer wall of the cable. Through the extrusion of the cable by multiple locking clips 806, when the winding is completed, the function of clamping the end of the cable can be realized, and the function of protecting the cable end interface can be realized.
