Therefore, the floating joint 51 needs to be adjusted first during adjustment, and the first tool use position is determined first; the trimming assembly is then readjusted to determine the second tool use position.

Specifically, after the height of the limiting block 311 is adjusted to a proper position, the limiting block 311 is locked on the fixing plate 1 by using a fastener. The second output rod 21 is connected with the chip suction hood 4 through a floating joint 51 and a guide shaft 52, thereby driving the chip suction hood 4 to move up and down.
When the first output rod 22 extends, the lifting assembly 2 and the chip suction cover 4 are pushed to move downwards.
