There is a belt transmission pair 22 between the output shaft of the motor 5 and the end of the main shaft 4, and the belt transmission pair 22 is in the form of a V-belt. A secondary shaft 9 parallel to the main shaft 4 is fixedly installed on the two vertical plates 2. An eccentric wheel 6 is fixedly installed on the main shaft 4 through a connecting key. One end of a crank 7 is movably connected to the eccentric wheel 6, and the other end of the crank 7 is connected to one end of a swing rod 8 through a pin shaft. The swing rod 8 is sleeved on the secondary shaft 9, and the swing rod 8 can rotate on the secondary shaft 9. And on the secondary shaft 9 on both sides of the swing rod 8, there are retaining rings for axially limiting the swing rod 8. The other end of the swing rod 8 is connected to one end of a connecting plate 10 through a pin shaft, and the other end of the connecting plate 10 is connected to one end of a tool holder 11 through a pin shaft. The tool holder 11 is located in the channel on a guide block 23, and the tool holder 11 can reciprocate relative to the guide block 23. Both sides of the guide block 23 are fixedly connected to the vertical plates 2. The other end of the tool holder 11 is fixedly connected with a tool bit 12 through a screw. On the two vertical plates 2, a material seat 13 with a feed inlet 14 and a support plate 21 are fixedly connected. There is a long hole 20 on the support plate 21. The end of a clamping bolt 17 is located in the long hole 20 and can only reciprocate along the length direction of the long hole 20 in the long hole 20. The screw part of the clamping bolt 17 passes through the hole on a material supporting adjustment plate 16 and is equipped with a nut 19. Rotating the nut 19 can fix the material supporting adjustment plate 16 on the support plate 21. The upper end of the material supporting adjustment plate 16 is located below the feed inlet 14 and forms a gap 15 with the feed inlet 14. The front end of the tool bit 12 faces the gap 15.
