The rotating motor 9 is a prior art, and the staff can turn on the rotating motor 9 to drive the object connected thereto to rotate through the motor shaft, and the motor shaft of the rotating motor 9 passes through the cavity 1 and Fixedly connected to one end of the rotating rod 3, two mutually symmetrically arranged tensioning components are slidably connected in the cavity 1, and the tensioning component includes a rack 10 slidably connected in the cavity 1, the rack 10 is meshed with the gear 4, and the end of the rack 10 away from the gear 4 is fixedly connected to a sliding block 11. Through the above structure, when the rotating motor 9 is turned on and its motor shaft rotates, the rotating rod 3 connected thereto also rotates, causing the gear 4 fixed thereto to rotate, driving the rack 10 to slide, and causing the sliding block 11 connected to the rack 10 to slide in the slot 2, thereby completing the tightening of the loose wire material;

[0021] The sliding block 11 is arranged in a T shape, and a stabilizing rod 12 is arranged on the end of the sliding block 11 away from the cavity 1, and support rods 13 are arranged at both ends of the stabilizing rod 12, and the upper ends of the two support rods 13 are fixedly connected with a fixing rod 14 together, and threaded rods 15 are threadedly penetrated on the two support rods 13, and the ends of the two threaded rods 15 close to each other are rotatably connected with a clamping block 16, and the ends of the four threaded rods 15 away from the four clamping blocks 16 are provided with knobs 24. The staff can easily drive the threaded rods 15 to rotate by rotating the knobs 24, so as to drive the clamping blocks 16 to slide on the fixing rod 14, and the two clamping blocks 16 are slidably connected to the fixing rod 14, and a protective layer is arranged on the side walls of the two clamping blocks 16 close to each other. Through the provision of the protective layer, the staff can reduce the damage to the wire when clamping the wire, and through the provision of the above-mentioned tensioning assembly, the staff can clamp the loose wire for bungee jumping, and at the same time can adapt to wires of different specifications to facilitate the cutting work;

[0022] A sliding opening 5 is provided on one side wall of the cavity 1, and a support block 6 is slidably connected in the sliding opening 5. The support block 6 is arranged in an L shape, and a cross bar 7 is provided at one end of the support block 6 away from the sliding opening 5, and a cutting device 8 is provided at one end of the cross bar 7. A wire taking-up assembly is provided on the outer wall of the cavity 1, and the wire taking-up assembly includes a wire taking-up body 17 arranged on the side wall of the cavity 1, and a rotating rod 18 is rotatably passed through the end of the wire taking-up body 17 away from the cavity 1, and a limiting platform 22 is provided on the rotating rod 18, and a slide rail 21 is provided on the rotating rod 18. A wire taking-up roller 19 is slidably connected to the rotating rod 18, and a slider 20 is provided in the wire taking-up roller 19, and the slider 20 is slidably connected to the slide rail 21. Through the above structure, after completing the cutting work, the staff can rotate the rotating rod 18 to drive the wire taking-up roller 19 slidably connected thereto to rotate, so that the wire material rotates around the wire taking-up roller 19 to complete the wire taking-up work, and then the wire taking-up roller 19 is easily taken out for use through the slide rail 21 and the slider 20, which meets the staff's use needs.

[0023] During the use of the utility model, the staff first places the mechanism stably in the specified position through the stabilizing effect of the pad 23, and then the staff can take out the wire, fix one end of the wire on the take-up roller 19, and then pass the wire over the two fixed rods 14. At this time, the staff can rotate the knob 24 to drive the threaded rod 15 to rotate through the knob 24. Since the threaded rod 15 threads penetrate the support rod 13, the rotation of the threaded rod 15 drives the clamping block 16 connected to the threaded rod 15 to slide on the fixed rod 14. As the two clamping blocks 16 approach each other, the wire is clamped. Repeat the above operation to clamp all the wires on the two fixed rods 14. At this time, the wire is in a relaxed state, so the staff can turn on the rotating motor 9, and drive the rotating rod 3 to rotate through the connection relationship between the motor shaft of the rotating motor 9 and the rotating rod 3, and rotate the gear 4 fixedly connected to the rotating rod 3, thereby driving the two racks 10 to slide in the cavity 1 and driving the fixed connection The sliding block 11 on the rack 10 slides. Since the sliding block 11 is set in a T shape, part of the sliding block 11 slides in the slot 2 at the same time, thereby driving the two tensioning components to move in opposite directions and slowly tightening the wire until the wire is tightened to a suitable level. Then the staff can adjust the sliding of the support block 6 through the connection relationship between the slide 5 and the support block 6, thereby adjusting the lateral position of the cutting device 8 to adapt to the cutting requirements of wires of different specifications. After the cutting work is completed, one end of the required wire is fixedly connected to the wire take-up roller 19. At this time, the staff rotates the rotating rod 18. Because the slider 20 in the wire take-up roller 19 is slidably connected to the slide rail 21 of the rotating rod 18, when the rotating rod 18 rotates, it will drive the wire take-up roller 19 to rotate together, and wind the wire around the wire take-up roller 19, thereby completing the wire taking-up work. Then the staff can easily take out the wire take-up roller 19 through the sliding connection relationship between the slider 20 and the slide rail 21, which is convenient for subsequent work.
