The cutting platform 21 and the reciprocating mechanism 23 are connected through a plurality of support rods, and the multiple support rods connected to the cutting platform 21 can all be telescopic in the vertical direction. , so as to be able to adapt to the reciprocating motion of the reciprocating mechanism 23 through multiple support rods. One end of the support rod is connected to the cutting platform 21, and the other end is connected to the mounting plate 231 on the top of the reciprocating mechanism 23. Therefore, when the reciprocating mechanism 23 reciprocates up and down, the support rod can follow the reciprocating mechanism 23 due to its scalability. It expands and contracts to adapt to the up and down movement of the reciprocating mechanism 23. Moreover, the support rod can not only expand and contract with the movement of the reciprocating mechanism 23, but also can adjust the length of the support rod to limit the telescopic stroke of the support rod.
