A first spring 9 is sleeved on the outer wall of the sliding rod 8. One end of the first spring 9 is fixedly connected to the inner wall of the fixing sleeve 3, and the other end of the first spring 9 is fixedly connected to a support plate 13. The support plate 13 is in contact with the slider 4. A fixing component is provided on the outer wall of the sliding rod 8. The fixing component is used for installing and fixing the placement board 1. The fixing component includes a turntable 10. The inside of the turntable 10 is fixedly connected to the outer wall of the sliding rod 8. An arc-shaped sliding groove 11 is formed inside the turntable 10. A clamping block 12 is slidably connected inside the turntable 10. The outer wall of the clamping block 12 is slidably connected to the fixing frame 14;

[0026] Specifically, first, press and rotate the sliding sleeve 5 to slide inside the positioning block 2, thereby driving the slider 4 to slide on the inner wall of the fixing sleeve 3. At the same time, through the movement of the slider 4, drive the limiting block 6 to slide in the U-shaped sliding groove 7 inside the fixing sleeve 3, and then cooperate with the support plate 13 to contract the first spring 9. Then rotate the sliding sleeve 5 to drive the limiting block 6 to slide inside the U-shaped sliding groove 7, so that the limiting block 6 slides to the other end of the U-shaped sliding groove 7. At the same time, drive the turntable 10 to slide inside the positioning block 2 through the rotation of the sliding rod 8, and then drive the clamping block 12 to slide through the arc-shaped sliding groove 11 inside the turntable 10, so that the clamping block 12 slides inside the positioning block 2 and the fixing frame 14 to realize the installation of the placement board 1. After installation, release the sliding sleeve 5. At this time, the first spring 9 is no longer stressed and rebounds, driving the limiting block 6 to move into the sliding track on the other side of the U-shaped sliding groove 7 for limiting, realizing locking. When disassembling, only need to pull the sliding sleeve 5 and then rotate it in the reverse direction to realize disassembly, achieving the effect of convenient disassembly and assembly.

[0027] Referring to Figure 1 、 Figure 5 andFigure 6 On the upper surface of the storage board 1, a base 15 is attached. Inside the base 15, a fixing bolt 16 is provided. The outer wall of the fixing bolt 16 is threadedly connected to the inside of the storage board 1. Inside the base 15, a fixing ring 17 is fixedly connected. On the outer wall of the fixing ring 17, a hinge 18 is fixedly connected. On the outer wall of the hinge 18, a movable ring 19 is fixedly connected. One end of the fixing ring 17 is rotatably connected to a screw rod 20. The outer wall of the screw rod 20 is threadedly connected to a threaded sleeve 21. The outer wall of the threaded sleeve 21 is attached to one end of the fixing ring 17. Inside both the fixing ring 17 and the movable ring 19, a telescopic rod 22 is fixedly connected. A second spring 23 is sleeved on the outer wall of the telescopic rod 22. One end of the second spring 23 is fixedly connected to the inside of the movable ring 19. The other end of the second spring 23 is fixedly connected to a clamping block 24;

[0028] Specifically, place the cable above the fixing ring 17, then pull the movable ring 19 to rotate around the hinge 18, so that the movable ring 19 fits with the fixing ring 17. Then, pull the screw rod 20 to move into the movable ring 19. Next, drive the threaded sleeve 21 to slide on the outer wall of the screw rod 20, so as to fix between the movable ring 19 and the fixing ring 17. Furthermore, fix the cable between the fixing ring 17 and the movable ring 19. Then, push the clamping block 24 through the second spring 23 to clamp the cable, so that the cable will not move randomly and cause frictional damage.

[0029] Working principle: When it is necessary to use the cable support for subway construction, first press and rotate the sliding sleeve 5 so that it slides within the positioning block 2, driving the slider 4 to slide on the inner wall of the fixed sleeve 3. The movement of the slider 4 drives the limiting block 6 to slide in the U-shaped chute 7 inside the fixed sleeve 3, cooperating with the support plate 13 to compress the first spring 9. Then, rotate the sliding sleeve 5 so that the limiting block 6 slides to the other end of the U-shaped chute 7. Through the rotation of the sliding rod 8, drive the turntable 10 to slide within the positioning block 2. Furthermore, through the arc-shaped chute 11 inside the turntable 10, drive the clamping block 12 to slide within the positioning block 2 and the fixed frame 14 to realize the installation of the storage board 1. After installation, release the sliding sleeve 5, and the first spring 9 rebounds, driving the limiting block 6 to move to the other slideway within the U-shaped chute 7 for limiting and realizing locking. When disassembling, just pull the sliding sleeve 5 to rotate in the reverse direction to disassemble, which is convenient and fast. Then, place the cable above the fixing ring 17, pull the movable ring 19 to rotate around the hinge 18 so that the movable ring 19 fits with the fixing ring 17, pull the screw rod 20 to move into the movable ring 19, drive the threaded sleeve 21 to slide on the outer wall of the screw rod 20 to fix the movable ring 19 and the fixing ring 17. Then, push the clamping block 24 through the second spring 23 to clamp the cable, preventing the cable from moving randomly and causing frictional damage. The whole process is simple to operate, ensuring the cable is firmly fixed and reducing the damage risk during construction.
