Specifically, the user can move the mounting plate 21 along the slide rail 11 by pulling and pushing the handle 26 in each sliding component 2. When it moves to the corresponding position, the position of the sliding component 2 can be fixed by twisting the fastening bolt 42 in the limiting part 4 so that one end of it enters the fixing groove 12 and abuts against its inner wall, thereby completing the adjustment work.

[0051] After the adjustment work is completed, the clamping part 3 can be pushed to move by controlling the multiple push rods 25, so that the workpiece can be clamped and fixed by the multiple clamping heads 34, so that subsequent workpiece processing work can be carried out.
