Both ends of the inner cavity of the jaw seat 19 are slidably connected with a jaw 21. Precision bearing steel balls 23 are embedded on both sides of the jaw 21.

[0022] By adjusting the height of the adjusting screw 2 to control the clamping stroke of the jaw 21, the function of compatible clamping of different products can be realized. The structure of the connecting rod 16 plus the precision bearing steel balls 23 enables the jaw 21 to slide parallel. Using hydraulic oil to drive the piston rod 9 can ensure that the jaw 21 has a large enough clamping force to clamp an object.

[0023] Among them, the jaw 21 is rotatably connected to the connecting rod 16. The top of the adjusting screw 2 is threadedly connected with a hexagonal nut 1, and the hexagonal nut 1 is of M24 type.
