A first groove 9 is provided on one side surface of the first clamping plate 8, and a second clamping plate 12 is movably connected inside the first groove 9, and the second clamping plate 12 clamps the hexagonal nut. A second groove 13 is provided on one side surface of the second clamping plate 12, and the maximum angle of the second groove 13 is one hundred and twenty degrees. A first threaded hole 14 is provided through the middle of the first clamping plate 8, and a second threaded hole 15 is provided in the middle of the other side of the second clamping plate 12. Bolts 16 are threadedly connected inside the first threaded hole 14 and the second threaded hole 15 to fix the second clamping plate 12 inside the first groove 9, and a spring 17 is connected inside the first groove 9.
[0020] Specifically, a slide groove 10 is provided at both the upper and lower ends inside the first groove 9, and a slider 11 is slidably connected inside the slide groove 10. One end of the slider 11 passes through the slide groove 10 and extends to the outside of the slide groove 10 to be connected to the second clamping plate 12, so that the second clamping plate 12 is more stable when moving left and right inside the first groove 9.
[0021] Furthermore, the surface of the threaded rod 5 is provided with opposite threads in the left and right directions. One end of the threaded rod 5 penetrates the processing table 1 and extends to the outside of the processing table 1 and is connected to the shaft end of the motor 4. The other end of the threaded rod 5 is rotatably connected to the inner wall of the processing table 1 through a bearing.

The two movable blocks 6 drive the two connecting rods 7 to move toward each other, and the two connecting rods 7 drive the two first clamping plates 8 to move toward each other. When the second clamping plate 12 contacts the square nut, the second clamping plate 12 will be squeezed into the first groove 9, so that the first clamping plate 8 clamps and fixes the square nut. When the hexagonal nut needs to be processed, the bolt 16 is rotated in the opposite direction so that the bolt 16 is transferred to the second threaded hole 15 on the second clamping plate 12 to fix the second clamping plate 12 and prevent it from moving inside the first groove 9. The two first clamping plates 8 are driven to move toward each other by the motor 4, and the hexagonal nut is clamped and fixed by the second clamping plate 12, so that the square nut and the hexagonal nut can be clamped, thereby improving work efficiency.
