The first driver 25 drives the second carrier 24 fixedly arranged with the cutter 21 to do vertical lifting movement, so as to drive the cutter 21 to do lifting movement along the vertical direction, and further ensure that the cutter 21 only moves along the vertical direction.
Specifically, as shown in fig. 4, the first driver 25 has a first telescopic shaft extending vertically, and an extending end of the first telescopic shaft is fixedly connected to the second carrier 24, so that the first driver 25 can drive the second carrier 24 to slide vertically; the second stage 24 has a first positioning piece 241 and a second positioning piece 242 having an L-shape on the top, and an installation space is formed between the L-shaped horizontal portions of the first positioning piece 241 and the second positioning piece 242 and the top of the second stage 24; the extending end of the first telescopic shaft extends outwards along the radial direction of the extending end to form a first protrusion 251, and the first protrusion 251 is clamped in the installation space, so that the first driver 25 is further guaranteed to drive the second carrying platform 24 to slide up and down along the vertical direction.
