[0038] Working principle: First, twist the bidirectional screw 8 to drive the cross bars 2 on both sides to move, so that they slide in the slide grooves 9 through the upper and lower sliders 10, drive the cross bars 2 on both sides to approach each other, and also drive the upper and lower rotating shafts 3 to move, and then drive the upper and lower movable bars 4 to rotate through the rotating shafts 3, thereby driving the upper and lower movable shafts 5, and then push the connecting block 6, thereby pushing the vertical rod 7, and the cross bars 2 on both sides are brought closer to each other and contracted, thereby pushing the upper and lower movable rods 73 to slide in the upper and lower first grooves 71, so that the vertical rod 7 and the cross bar 2 form a four-sided encirclement and limiting clamping, clamping the workpiece on the placement plate 1, ensuring stability during processing, preventing deviation, and making the processing more accurate. To make the processing more efficient, the micro motor 16 is operated to rotate inside the mounting block 11, and the rotating rod 17 is driven to rotate, thereby driving the turntable 18 to rotate, and the fixed block 19 pushes the special-shaped gear 20 to rotate, thereby driving the connecting rod 21 to rotate, and driving the placement plate 1 to rotate to adjust the angle of the clamped workpiece, so that the processing is more precise, and the first motor 15 is operated to operate on one side of the bed 14, and the screw 12 is driven to rotate in the second groove 13, so that the mounting block 11 is threadedly moved on its surface, thereby driving the placement plate 1 to move left and right, which can be adjusted according to the processing position of the workpiece, so that the processing is more efficient.
