The fixing frame 17 is fixedly connected to both sides of the groove on the lower clamping seat 1. The pull rod 18 is movably connected to the middle of the fixing frame 17. The second connecting member 19 is fixedly connected to the outer surface of the pull rod 18. Both ends of the spring 20 are fixedly connected between the fixing frame 17 and the second connecting member 19. The second handle 21 is fixedly connected to one end of the pull rod 18. The lower clamping seat 1 and the upper clamping seat 2 are both made of high-strength alloy material, have excellent wear resistance and corrosion resistance, and can be used for a long time in harsh working environment.

[0023] Two lower clamping grooves 23 are symmetrically provided on the upper surface of the lower clamping seat 1, and an upper clamping groove 22 is symmetrically provided at the bottom end of the upper clamping seat 2. The clamping device 4 includes a pressing plate 11, a second gasket 12, a bearing seat 13, a second bolt 14, a washer 15, and a first handle 16. The pressing plate 11 is movably connected to the inside of the upper clamping groove 22, the second gasket 12 is fixedly connected to the bottom end of the pressing plate 11, the bearing seat 13 is fixedly connected to the upper surface of the pressing plate 11, one end of the second bolt 14 is rotatably connected to the bearing seat 13, the first handle 16 is fixedly connected to one end of the second bolt 14 away from the bearing seat 13, the washer 15 is movably connected to the outer surface of the second bolt 14, and the second gasket 12 is made of high-temperature resistant rubber material, which can maintain good sealing and elasticity in a high temperature environment to ensure the clamping effect.

[0024] A plurality of threaded holes 7 are provided on one side of the lower clamping seat 1 and the upper clamping seat 2 close to the hinge 5, a plurality of first bolts 10 are threadedly connected between the hinge 5 and the threaded holes 7, the upper clamping groove 22 and the lower clamping groove 23 are of the same size, a first gasket 6 is fixedly connected to the inner wall of the lower clamping groove 23, a small circular hole is provided inside the groove on the lower clamping seat 1, the small circular hole and the circular hole 9 are consistent with the diameter of the pull rod 18, the pressure plate 11 is arc-shaped, a bearing is provided inside the bearing seat 13, and the first gasket 6 is made of wear-resistant engineering plastic material, which can effectively reduce friction and improve clamping stability.

[0025] Working principle: First, place the cable to be fixed between the lower clamp seat 1 and the upper clamp seat 2 to ensure that the cable is correctly aligned for the subsequent fixing and clamping process. The operator pulls the second handle 21, which will drive the pull rod 18 to move along the middle of the fixing frame 17. The pull rod 18 transmits the force to the fixing frame 17 and the second connecting member 19 by cooperating with the fixing frame 17. As the pull rod 18 moves, the second connecting member 19 will also move accordingly, compressing or releasing the spring 20 to generate an elastic rebound force. The spring 20 provides the rebound force so that the pull rod 18 and the second connecting member 19 are always in a stable stress state, thereby fixing or releasing the power fittings. The upper clamp seat 2 is connected to the lower clamp seat 1 by the hinge 5. The operator can open the upper clamp seat 2 upward or outward through the hinge 5 to facilitate the placement and removal of the cable. After placing the cable in the appropriate position, the operator can close the upper clamp seat 2 through the hinge 5 to prepare for clamping. The second bolt 14 is rotated by rotating the first handle 16, and one end of the second bolt 14 is connected to the pressure plate 11 through the bearing seat 13. As the second bolt 14 rotates, the pressure plate 11 moves up and down in the upper clamping groove 22, and the pressure plate 11 moves downward, gradually contacts the cable and applies pressure to firmly clamp the cable between the lower clamping seat 1 and the upper clamping seat 2. The pressure plate 11 is designed to be arc-shaped, so that it can better fit and fix objects of irregular shapes, ensuring that the clamping effect is more reliable. A bearing is provided in the bearing seat 13, so that the second bolt 14 is smoother when rotating and adjusting the clamping force. The outer surface of the second bolt 14 is movably connected with a washer 15, which can effectively disperse the pressure and prevent the surface of the upper clamping seat 2 from being damaged. The inner wall of the lower clamping groove 23 is fixedly connected with the first gasket 6, and the second gasket 12 is fixedly connected to the bottom end of the pressure plate 11. The use of the second gasket 12 increases the friction during clamping, prevents sliding, and improves the clamping effect.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
