Through the connection of the movable clamping blocks 2 and the pressure groove 4, and the connection of the fixed clamping plate 1 and the placement groove 3, the clamping and support effect of the wire is achieved.

[0025] Furthermore, the adjusting screw 21 passes through the surface of the fixed clamping plate 1 via the connecting groove 22, and the movable clamping block 2 abuts against the fixed clamping plate 1 via the adjusting screw 21 and the screw sleeve 23. Through the connection between the movable clamping block 2 and the adjusting screw 21, and the connection between the adjusting screw 21 and the connecting groove 22, the connection between the adjusting screw 21 and the screw sleeve 23 is achieved, thereby realizing the adjustment and support effect of the position of the movable clamping block 2 on the fixed clamping plate 1.

[0026] Furthermore, a groove is provided in the middle of the movable clamping block 2. The movable clamping block 2 is inserted into the fixed clamping plate 1 through the groove.
