Two through holes are opened on the top outer wall of the extrusion block, and two limit rods are slidably mounted in the two through holes respectively.

[0011] Preferably, the moving block is a right-angled trapezoidal structure, and the inclined surface of the moving block abuts against the inclined surface of the extrusion block. Slide grooves are opened on the outer walls of both sides of the connecting plate and one side of the two mounting plates, and the slider is slidably installed in the slide grooves. One end of the two tension springs is respectively clamped on the outer walls of the two limit rods.

[0012] Through the above scheme, by rotating the two screws separately, the screws drive the extrusion block to descend, and the extrusion block squeezes the two moving blocks, so that the two moving blocks and the two sliders start to move away from each other, and stretch the four tension springs until one side of the moving block contacts the component of the square structure and squeezes the component.

[0013] Preferably, the top of the mounting plate is located on the outer wall of the bottom of the fixed pad and two fixing rods are respectively inserted into the two fixing holes; the top of the mounting plate is located on the outer wall of the bottom of the movable pad and two slides are respectively slidably installed in the two slides; the connecting rods respectively pass through and are slidably installed on the outer wall of one side of the fixed pad, and a limit block is fixed on the outer wall of one end of the connecting rod.

[0015] Through the above scheme, the moving block moves to contact and squeeze the parts of the square structure, and at the same time the moving block drives the moving pad, the connecting rod and the two slide rods to move along the two slides, so that the fixed pad and the moving pad are close to each other and suitable for supporting square parts of different specifications.

[0016] The beneficial effects of the utility model are:

[0017] 1. An adjustment mechanism and an extrusion assembly are provided. The two screws are rotated respectively. The screws drive the extrusion block to descend. The extrusion block squeezes the two moving blocks, causing the two moving blocks and the two sliders to start to move away from each other, and stretches the four tension springs until one side of the moving block contacts and squeezes the parts of the square structure. It can squeeze and clamp multiple parts of the same specification at the same time, so that multiple parts can be turned at the same time, which improves work efficiency.

[0018] 2. A supporting pad and a fixed block are provided. The movable block moves to contact and squeeze the parts of the square structure. At the same time, the movable block drives the movable pad, the connecting rod and the two slide rods to move along the two slides, so that the fixed pad and the movable pad are close to each other and suitable for supporting square parts of different specifications. It can support square parts of different specifications without replacing the pad, thereby improving practicality.

[0019] To sum up, the utility model can extrude and clamp multiple parts of the same specifications at the same time, so that multiple parts can be turned at the same time, which improves work efficiency. It can support square parts of different specifications without replacing the pads, thereby improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS
