[0028] The lower ends of the left and right sides of the front side plates of the U-shaped plate 21 are respectively fixedly connected to the two inner sleeve columns 26, and the two inner sleeve columns 26 are respectively sleeved with the elliptical holes opened at the front ends of the two limit pull plates 27. The rear end opposite sides of the two limit pull plates 27 are fixedly connected to the clamping shaft 28, and the clamping shaft 28 is adapted to the clamping groove 29 opened at the lower end of the rear side of the rear side plate of the U-shaped plate 21. The lower end of the inner rear side of the U-shaped plate 21 is fixedly connected to the inner card plate 210. The cable 1 is placed in the U-shaped plate 21 on the clamping assembly 2 and overlapped on the inner card plate 210. Then, the clamping shaft 28 is pulled under the movable connection of the inner sleeve shaft 26, and the clamping shaft 28 is rotated to the rear side of the U-shaped plate 21 and aligned with the clamping groove 29. The top tightening wire 24 is then rotated by a tool to move under the support of the front side plate of the U-shaped plate 21, so that the push plate on the top tightening wire 24 is pressed against the top tightening plate 23 to push it to move. In this way, the top tightening plate 23 can move backward under the restriction of the sliding column 22 and contact and tighten the cable overlapped on the inner card plate 210. In this way, the top tightening plate 23 can push the cable 1 to squeeze the inner card plate 210, so that the inner card plate 210 pushes the rear side plate of the U-shaped plate 21 to tilt slightly backward. At the same time, the rear side plate of the U-shaped plate 21 is pulled and restricted by the clamping shaft 28, so that the top tightening plate 23 is continuously tightened to maintain the force storage and tightening state, so that the force storage and clamping state can be achieved.

[0029] The front side plate of the U-shaped plate 21 is threadedly connected to the tensioning wire 24, and the tensioning wire 24 is threadedly connected to the groove ring 25.

The outer wall surface of the rotating ring 243 is fixedly connected to the fixing plate 244, and the bottom surface of the fixing plate 244 is fixedly connected to the clamping plate 245. The lower end of the threaded rod 241 is fixedly connected to a second inner hexagonal plate, and the second inner hexagonal plate is rotated by a tool to drive the threaded rod 241 to rotate. The threaded rod 241 rotates, so that the threaded rod 241 drives it to descend under the fixed support of the tensioning wire 24, and the threaded rod 241 drives the fixed ring 242 and the rotating ring 243 to descend, so that the rotating ring 243 drives the clamping plate 245 on the fixed plate 244 to descend and clamp with the corresponding clamping groove on the outer surface of the corresponding clamping groove ring 25. In this way, the tensioning wire 24 can be restricted from rotating, and then another section of the connected cable can be clamped and fixed with another clamping assembly 2, so that it can be used for tensile resistance.

[0031] The five insulating layers 12 are all made of cross-linked polyolefin material, the filling layer 13 is made of silicone material, the isolation layer 14 is made of polyester tape, the tensile layer 15 is made of polyurethane material, and the outer layer 16 is made of nylon material. By making the isolation layer 14 use polyester tape, the tensile layer 15 use polyurethane material, and the outer layer 16 use nylon material, the overall tensile effect of the cable 1 can be enhanced.

[0034] The upper surface of the inner card plate 210 is set to an arc shape and a rubber layer is fixedly connected to the surface. Through the set rubber layer, when the inner card plate 210 and the outer surface of the cable 1 are pressed against the tightening plate 23, the rubber surface is in contact to increase friction, thereby increasing the tensile effect.

[0035] The operating steps of the utility model are:

[0036] The cable 1 can be placed in the U-shaped plate 21 on the clamping assembly 2 and overlapped on the inner clamping plate 210. Then, the clamping shaft 28 is pulled under the active connection of the inner sleeve shaft 26 to rotate the clamping shaft 28 to the rear side of the U-shaped plate 21 and correspond to the clamping groove 29. Then, the top tightening wire 24 is rotated by the tool to move under the support of the front side plate of the U-shaped plate 21, so that the push plate on the top tightening wire 24 pushes the top tightening plate 23 to move it. In this way, the top tightening plate 23 can move backward under the restriction of the sliding column 22 and contact the cable overlapped on the inner clamping plate 210 and tighten it. In this way, the top tightening plate 23 can push the cable 1 to squeeze the inner clamping plate 210, so that the inner clamping plate 210 pushes the rear side plate of the U-shaped plate 21 to tilt slightly backward. At the same time, the rear side plate of the U-shaped plate 21 is pulled and restricted by the clamping shaft 28, so that the top tightening plate 23 is continuously tightened to maintain the force storage and tightening state, so that the force storage and clamping state can be achieved.

[0037] Then, the second hexagonal plate is rotated by a tool to drive the threaded rod 241 to rotate, so that the threaded rod 241 is driven to descend under the fixed support of the tensioning wire 24, and the threaded rod 241 drives the fixed ring 242 and the rotating ring 243 to descend, so that the rotating ring 243 drives the clamping plate 245 on the fixed plate 244 to descend and clamp with the corresponding clamping groove on the outer surface of the corresponding clamping groove ring 25, so that the tensioning wire 24 can be formed into a state of restricted rotation, and then the other connected cable section can be clamped and fixed with another clamping assembly 2, so that it can be used for tensile resistance.
