The cutting unit 2 includes a drive shaft 21, a limiting ring 211 is fixedly sleeved on the outer wall of the drive shaft 21, and a detachable blade assembly 22 is inserted into the drive shaft 21. The blade assembly 22 is magnetically connected to the limiting ring 211. A T-shaped extension 214 is installed on one end of the drive shaft 21 near the blade assembly 22, and a movable part 215 is movably sleeved on the outer wall of the T-shaped extension 214. The blade assembly 22 and the drive shaft 21 are limited by the movable part 215.

[0022] Four guide rods 213 are installed in a circular array at equal intervals on the outer wall of the drive shaft 21 and between the T-shaped extension 214 and the limiting ring 211. Multiple guide blocks 216 are installed on the outer wall of the T-shaped extension 214 on the side of the drive shaft and at the corresponding guide rods 213.

[0023] The outer diameter of the movable part 215 is the same as the outer diameter of the drive shaft 21, and multiple limiting protrusions are installed on the outer wall of the movable part 215 at the corresponding guide rod 213.

[0024] The movable part 215 has a guide groove 217 on the side near the drive shaft 21 for the guide block 216 to be inserted, and the guide groove 217 is parallel to the limiting protrusion.

[0025] The cutter assembly 22 includes a mounting ring 221, which includes a fixed ring portion and an extension ring portion. The mounting ring 221 has mounting holes for the drive shaft 21 and the guide rod 213 to be inserted. Two cutter bodies 223 are mounted in a ring array on the side of the fixed ring portion adjacent to the extension ring portion.

[0026] The extension ring is magnetically connected to a limiting component on the side of the T-shaped extension 214. The limiting component includes a magnetic ring 222, and the outer wall of the magnetic ring is provided with multiple clearance grooves at equal intervals. The clearance grooves facilitate the user to pick up the magnetic ring. The inner side of the magnetic ring 222 is connected to a locking protrusion 224 through an extension seat at the corresponding guide groove 217. A magnetic groove is provided on one side of the extension ring for the magnetic ring and the corresponding locking protrusion 224 to be inserted. The inner wall of the magnetic groove is provided with a magnetic layer two with opposite polarity to the magnetic ring.
