The fixing plate two 820 is slidably connected with the fixing rod two 830, and the fixing rod two 830 is fixedly connected with the dial block 840.

[0049] The limiting mechanism 500 includes a limiting hole 510, a limiting pin 520, a driven top block 530 and a driving push plate 540.

[0052] In the present utility model, when the first cylinder 410 drives the supporting block 420 to move between the two pressing blocks 726, the lower end of the driven top block 530 moves from the low position section of the active push plate 540 to the high position section along the inclined surface. When passing through the inclined plate of the active push plate 540, the driven top block 530 slides upward in the slider supporting block 420 through the limiting hole 510, and the driven top block 530 drives the limiting pin 520 to insert into the bottom of the hardware plastic part, so that the hardware plastic part can only rotate around the limiting pin 520; after the first grinding, when the first cylinder 410 drives the supporting block 420 to reset, the fourth cylinder 810 pushes the shifting block 840 to move, and the shifting block 840 moves horizontally along the second fixed rod 830 under the limitation of the second fixing plate 820 and the second fixed rod 830. The hardware plastic part is blocked by the shifting block 840 during the movement and rotates 90 degrees around the limiting pin 520 to achieve the automatic rotation effect.

The limiting pin 520 locks and unlocks the hardware plastic part, so that the position of the hardware plastic part remains unchanged during the movement; the four surfaces of the hardware plastic part are polished, which is convenient for operation and improves the efficiency of deburring.
