[0027] The height of the movable block 34 is adjusted by the lifting member, the movable block 34 is lowered below the second support 33, the first support 32 and the second support 33 are high and low respectively, the cable can be placed between the fixed seat 31 and the movable block 34 through the gap between the second support 33 and the movable block 34, the movable block 34 is raised by the lifting member, and the movable block 34 fixes the cable. It can be applied to cables of different diameters, has high flexibility, the movable block 34 is fixed with the lifting member in a detachable manner, and replacement and maintenance are convenient.

[0028] It is worth noting that the second support 33 is provided with a limiting groove at the lower end, and a sliding block 35 is slidably arranged in the limiting groove. The sliding block 35 is fixedly connected to the side of the movable block 34 away from the first support 32. The sliding block 35 fixed to the side of the movable block 34 can limit the movable block 34 from the side away from the lifting member through cooperation with the limiting groove, thereby improving the stability of the movable block 34 during sliding.

[0029] Regarding the clamp 2:

[0030] The clamp 2 comprises a first clamp plate 21 and a second clamp plate 22. The opposite ends of the first clamp plate 21 and the second clamp plate 22 are hingedly connected by a pivot. The other ends of the first clamp plate 21 and the second clamp plate 22 are fixedly connected with a bolt plate 23, and the bolt plate 23 is threadedly connected with a fixing bolt 24.

The outside of the movable block 34 is provided with a bolt connecting piece for limiting the movement of the cable clamp 3. The nut seat 37 is assembled on one side of the movable block 34 in a plug-in manner. When the movable block 34 is removed from the nut seat 37, the fixing of the insertion block 4 by the bolt connecting piece is released, and the insertion block 4 can be pulled out of the insertion groove 41 on the side of the movable block 34.

[0036] Specifically, the bolt connecting piece includes a positioning bolt 43, which is threadedly connected to the outside of the movable block 34. The positioning bolt 43 penetrates into the insertion groove 41 and is threadedly connected with a positioning hole 42 formed on the outside of the insertion block 4. After the insertion block 4 is inserted into the insertion groove 41, the positioning bolt 43 is screwed into the insertion groove 41. The positioning bolt 43 cooperates with the positioning hole 42 to ensure that the nut seat 37 and the movable block 34 cannot be separated.
