The two fixing bolts 17 are symmetrically arranged on the left and right. A limit plate 16 is fixedly connected to the outer side of the fixing bolts 17 near the top.

[0020] Working principle: The positioning plate 9 is placed on the top of the mounting base 1, and the fixing bolt 17 is rotated to fix the positioning plate 9. Then, the swing plate 18 is flipped so that the swing plate 18 fits into the slot on the outside of the limit plate 16 to prevent the fixing bolt 17 from loosening due to vibration and impact during long-term, high-load, and intermittent cutting. The fixing spring 20 keeps the swing plate 18 and the limit plate 16 in contact. When the oil cylinder 6 is started, the push rod 8 can be driven to move to the left through the power output shaft. When the push rod 8 moves, the inclined edge at the top fits into the inclined opening of the inner cavity of the lifting rod 15, which can drive the lifting rod 15 to move upward. When the lifting rod 15 moves upward, the fixing block 14 can drive the two clamping plates 13 to flip. When the two clamping plates 13 flip, the workpiece 2 can be fixed. The movement trajectory of the push rod 8 can be limited by the anti-detachment plate fitting into the limit groove. The reset efficiency of the lifting rod 15 can be improved by setting the reset spring 12. When it is necessary to clean the iron filings inside the workpiece 2, the lower motor 29 can be started to drive the gear 31 to rotate. When the gear 31 rotates, it can mesh with the annular toothed plate 3, thereby driving the slider 32 to move. When the slider 32 moves, it can move along the annular groove to achieve annular movement. When the slider 32 moves in annular movement, it can drive the magnetic rod 34 to move synchronously in annular movement. When the upper motor 26 is started, it can drive the reciprocating screw 22 to rotate. When the reciprocating screw 22 rotates, it can drive the meshing plate 24 to move downward. Through the contact of the vertical plate 23 and the sliding plate 25, the movement trajectory of the meshing plate 24 can be limited. When the meshing plate 24 moves downward, it can drive the magnetic rod 34 into the inner cavity of the workpiece 2 to achieve adsorption of iron filings.
