[0030] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0031] like Figure 3 As shown, the outer wall of the shaft 3 is symmetrically provided with first lugs 14, and the shaft 3 is provided with a plurality of first through holes 15 penetrating the cavity, and the through holes are matched with the locking blocks 601 on the locking block 601 group 6 to limit the position of the saw blade 5;

[0032] The saw blade 5 is provided with a groove 501 matched with the first lug 14, and the two inner walls of the groove 501 are provided with second through holes 502 symmetrically arranged along the axis thereof, and the second through hole 502 is consistent in size with the locking block 601, and when the bidirectional screw 7 is rotated in a certain direction, the locking block 601 group 6 moves outward, passes through the first through hole 15, and enters into the second through hole 502 of the saw blade 5, so as to realize the locking of the locking mechanism, and after unlocking, the saw blade 5 can be adjusted to different positions to meet production needs.

[0033] like Figure 1 As shown, the shaft rod 3 is rotatably provided with a concave frame 16, and the concave frame 16 is threadedly connected to the reciprocating screw rod 9.

The diameter of the first gear 29 is larger than that of the second gear 30. The two are in the same plane and mesh with each other.
