A cover plate 2 is clamped on the top of the bottom plate 1, and a lifting assembly 9 is provided on the cover plate 2. A base 3 is also provided inside the bottom plate 1, and a wire threading groove 4 is provided at the bottom of the movable seat 5 and the top of the base 3. The setting of the wire threading groove 4 can facilitate the passage of cables. At the same time, the movable seat 5 can cooperate with the base 3 to limit the cables after moving down.

[0040] Specifically, the clamping assembly 8 includes a clamping groove 811, a through cavity 801 opened inside the bottom plate 1, and a threaded shaft 803 threadedly connected to the bottom of the bottom plate 1. The top of the threaded shaft 803 extends into the through cavity 801 and is connected to a push plate 802 through a bearing. Two first movable blocks 804 are arranged at the lower part of the through cavity 801, and a first push block 808 is installed on one side of the two first movable blocks 804 through a connecting rod. A second push block 810 and an adjustment block 812 are respectively arranged on both sides of the through cavity 801. The second push block 810 and the through cavity 801 are connected to each other. Sliding connection, a knob is installed at the bottom end of the threaded shaft 803 so that the second push block 810 can slide inside the through cavity 801. At the same time, when the second push block 810 moves, it will push the adjustment block 812 to move. The second movable block 809 is installed at the bottom of the second push block 810 through a connecting rod. Both sides of the push plate 802 are in contact with the first movable block 804. The first movable block 804 is slidably connected to the through cavity 801. When the push plate 802 moves upward, it will push the two first movable blocks 804 to move, and the first movable block 804 will drive the first push block 808 to move.

[0041] See also Figure 1-Figure 4 A card block 813 is provided on one side of the adjustment block 812, and the card slot 811 is opened on both sides of the inner part of the cover plate 2. The card block 813 corresponds to the card slot 811. When the card block 813 is inserted into the card slot 811, the cover plate 2 can be limited and fixed to prevent the cover plate 2 from moving. The adjustment block 812 contacts the second push block 810, and the second movable block 809 contacts the first push block 808. When the second push block 810 moves up, it will push the adjustment block 812 to move, so that the adjustment block 812 drives the card block 813 to move. The two sliders 805 are connected to the bottom of the two first movable blocks 804, and the two sliders 805 are connected to one side of the two second movable blocks 809. The other two The slider 805 is connected to the top of the adjusting block 812 so that the slider 805 can be driven to move when the first movable block 804, the second movable block 809 and the adjusting block 812 move, and the stability of the first movable block 804, the second movable block 809 and the adjusting block 812 when they move is improved. Two slide grooves 807 are provided at the lower part, both sides and the upper part of the through cavity 801. A spring 806 is fixed inside the slide groove 807, and one end of the spring 806 is connected to the slider 805. When the slider 805 slides inside the slide groove 807, it squeezes the spring 806, so that the spring 806 is compressed, which is convenient for pushing the slider 805 to reset and move.

[0042] Specifically, the lifting assembly 9 includes three movable columns 901 installed on the top of the cover plate 2 through bearings, and a threaded groove 905 is opened at the bottom end of the movable column 901, and a turntable 902 is installed on the top of a movable column 901, and the internal thread of the threaded groove 905 is connected to a threaded column 906, and a movable seat 5 is installed at the bottom end of the threaded column 906. The outer walls of the three movable columns 901 are all sleeved with sprockets 903, and a chain 904 is meshed and connected between every two sprockets 903. When the position of the movable seat 5 needs to be adjusted, the user can rotate a movable column 901 through the turntable 902, and then drive the sprocket 903 sleeved on the surface of the movable column 901 to rotate.

[0043] Embodiment 2:

[0044] On the basis of the above-mentioned embodiment 1, since the threaded column 906 will drive the movable seat 5 to move when it moves up and down, in order to improve the stability of the movable seat 5 when it moves and prevent the movable seat 5 from rotating, the movable seat 5 can be guided by the following structure so that the movable seat 5 can only move up and down.

[0045] See also Figure 2 Limiting grooves 6 are provided on both sides of the interior of the bottom plate 1 and both sides of the partition 10. A limiting block 7 is arranged inside the limiting groove 6, and one side of the limiting block 7 is connected to the movable seat 5. The movable seat 5 is slidably connected to the limiting groove 6 through the limiting block 7. When the movable seat 5 moves, it will drive the limiting block 7 to slide inside the limiting groove 6, thereby improving the stability of the movable seat 5 when moving.

[0046] The working principle of the utility model is as follows: first, when the cover plate 2 needs to be installed, the user covers the cover plate 2 on the bottom plate 1 and after the card block 813 is aligned with the card slot 811, the user can rotate the threaded shaft 803 to move the push plate 802 upward, and then push the two first movable blocks 804 to move, and then drive the first push block 808 to move, and the first push block 808 pushes the second movable block 809 to move, and then drives the second push block 810 to move upward, and the second push block 810 pushes the adjustment block 812 to move, so that the adjustment block 812 is brought The movable block 813 moves so that the block 813 is inserted into the slot 811, thereby limiting and fixing the cover plate 2 to prevent the cover plate 2 from moving. Then, the cable is passed through the threading groove 4 for wiring. After the wiring is completed, the user can rotate a movable column 901 through the turntable 902, and then drive the sprocket 903 sleeved on the surface of the movable column 901 to rotate, and then drive the other two movable columns 901 to rotate through the chain 904. At this time, the threaded column 906 moves downward and drives the movable seat 5, so that the movable seat 5 presses the cable.

[0047] When the cable needs to be repaired, the user can reversely rotate a movable column 901 through the turntable 902, and then drive the sprocket 903 sleeved on the surface of the movable column 901 to rotate, and then drive the other two movable columns 901 to rotate through the chain 904. At this time, the threaded column 906 moves up and drives the movable seat 5 to move up, so that the movable seat 5 no longer presses the cable, allowing the user to repair the cable.
