[0020] When assembling the bridge, the handle 10 can be rotated to drive the stud 27 to rotate. The stud 27 can drive the sliding block 23 and the push plate 8 to move forward synchronously. The push plate 8 applies a thrust to the multiple top covers 2 to drive the top covers 2 to move forward. The top covers 2 apply a thrust to the moving block 21 to make the moving block 21 slide on the end surface of the top cover 2. Then, with the use of two push-pull rods 19 and spring three 20, the positioning mechanism of the front seat 4 can be moved down. At the same time, the forward movement of the sliding block 23 and the use of the connecting rod 25 can make the positioning mechanism of the rear seat 7 move down. The two positioning mechanisms are pressed against the cable to achieve the locking and fixing of the cable, thereby improving the stability of the connection between the cable and the frame 1. Furthermore, the multiple top covers 2 are pressed against each other to improve the tightness of the connection between the top cover 2 and the frame 1, so as to achieve the purpose of rapid assembly, replace the traditional bolt fixing, and have flexible and convenient operation and strong practicality.

[0021] When inspecting the cable, the rotatable handle 10 drives the stud 27 to rotate, and the stud 27 can drive the sliding block 23 and the push plate 8 to move back synchronously. The push plate 8 is separated from the top cover 2, and the stretched spring three 20 can drive the positioning mechanism of the front seat 4 to move upward, and the sliding block 23 pulls the positioning mechanism of the rear seat 7 to move upward, so as to loosen the cable. At this time, the top cover 2 is in a relaxed state, and the handle 3 can be operated to open the corresponding top cover 2, which is convenient for inspecting the cable at the corresponding position, instead of the traditional method of opening the entire top cover 2, thereby improving the inspection efficiency.

The spring 12 is located in the vertical slot 11, and both ends of the spring 12 are connected to the pressing plate 5 and the pressing rod 6. The sphere 26 is connected to the end of the pressing rod 6. When the pressing plate 5 moves downward, the sphere 26 presses on the cable, the spring 12 is compressed, and the pressing rod 6 also moves upward synchronously. The pressing rod 6 and the sphere 26 are provided in plurality. According to the different diameters of the cables, the compression amount of the spring 12 is also different, which can be applied to the compression and fixation of different cables, improve the stability of the connection between the cable and the frame 1, and is convenient to use and has strong applicability.

[0023] The surfaces of the sphere 26 and the pressing rod 6 are both smooth, which can reduce the frictional force in contact with the cable.

[0024] The pressing rod 6 is slidably connected to the vertical slot 11 , and the spacing between adjacent vertical slots 11 is equal, so as to improve the stability of the lifting and lowering of the pressing rod 6 .

[0025] The driving mechanism 1 includes two push-pull rods 19, a spring 3 20, and a moving block 21. The two ends of the push-pull rod 19 are connected to the front seat 4 and the moving block 21, and the two ends of the other push-pull rod 19 are connected to the moving block 21 and the positioning mechanism, and the two ends of the spring 3 20 are connected to the two push-pull rods 19. When the top cover 2 moves forward, the top cover 2 presses on the moving block 21, so that the moving block 21 slides on the end surface of the top cover 2, so that the angle between the two push-pull rods 19 gradually increases, and the spring 3 20 is gradually stretched, thereby driving the corresponding pressing plate 5 to move downward, which is convenient for locking the cable.

At the same time, the forward movement of the sliding block 23 and the use of the connecting rod 25 can make the positioning mechanism of the rear seat 7 move downward. The two positioning mechanisms are pressed against the cable to lock and fix the cable, and the assembly of the bridge is also realized, which is highly practical. Step three: When maintenance is needed, the rotatable handle 10 drives the stud 27 to rotate, so that the push plate 8 and the sliding block 23 move back synchronously, and the stretched spring three 20 can drive the positioning mechanism of the front seat 4 to move up, and the sliding block 23 can pull the positioning mechanism of the rear seat 7 to move up.
