Two support blocks 2 are provided. A support block 3 is provided on the upper side of the support block 2. A square hole 4 is opened on the front side of the support block 2, and a square hole 5 is opened on the front side of the support block 3. Four square holes 4 and 5 are provided, corresponding one-to-one. A rotating structure 8 is provided between the support blocks 2 and 3. A clamping structure 6 is provided inside the square holes 4 and 5. A fixing structure 7 is provided on the outer side of the support blocks 2 and 3. The clamping structure 6 includes a square groove 601, which is opened on the left side inside the square hole 4. The square groove 601 contains... There is a spring 602, and clamping blocks 603 are set in square holes 4 and 5. The left end of the spring 602 is fixedly connected to the support block 2, and the right end of the spring 602 is fixedly connected to the clamping block 603. The clamping block 603 is slidably connected to the support block 2 and the support block 3. When the workers sort the cables and put them into the square holes 4 of the different support blocks 2, before putting them into the square holes 4, the workers first push the clamping block 603. The clamping block 603 compresses the spring 602 and moves to put in the cable. Then the clamping block 603 is released. The clamping block 603 clamps and fixes the cable under the action of the spring 602 to prevent it from falling out of the square holes 4 of the support block 2 during the cable laying process.

[0026] The rotating structure 8 includes a rotating groove 801, which is located on the right side of the support block 2. A rotating groove 802 is located on the right side of the support block 3. A rotating rod 803 is installed inside the rotating groove 801, and a rotating block 804 is installed inside the rotating groove 802. The rotating block 804 is fixedly connected to the support block 3, and the rotating rod 803 is also fixedly connected. The rotating rod 803 is rotatably connected to the support block 2. The fixing structure 7 includes a groove 701 and a groove 702, which are located on the upper side of the support block 3. Four grooves of each type are provided, and they are distributed in a one-to-one correspondence. A round rod 703 is installed inside each groove.

After the cable is laid and arranged, the worker holds the second bracket block 3 and controls the rotating block 804 and the rotating rod 803 of the second bracket block 3 to rotate. Then, the square hole 25 is aligned with the square hole 14 to prevent the cable from being misaligned. Then, the worker controls the locking block 705 on the outside of the groove 1 701 and the groove 2 702 and locks the locking block 705 on the lower side of the first bracket block 2. Then, the worker holds the cylindrical block 708 and rotates the cylindrical block 708 to drive the threaded rod 707 to rotate. The threaded rod 707 rotates into the round hole 706 and then fixes the first bracket block 2 and the second bracket block 3 to prevent the cable from falling out of the square hole 14.

[0027] Working principle: First, when laying cables, workers fix the support plate 1 to the outside of the tunnel wall. Then, according to the function of the cables, they classify them into different square holes 4 and fix them with clamping structure 6. After the cables are laid in categories and fixed, the rotating structure 8 is activated to place the laid cables in square holes 4 and square holes 5, preventing cables from different square holes 4 from being misplaced into other square holes 4. Then, the fixing structure 7 is used to fix the support block 2 and support block 3. In this way, the cable laying is completed and the cables are laid neatly. If there is a problem with the cables, it is easy for workers to find the problematic cables.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
