the telescopic mechanism is connected with the sliding plate;

The lifting driving piece is connected with the telescopic mechanism and is used for driving the telescopic mechanism to move, so that the telescopic mechanism drives the material breaking assembly to move towards the limiting jig along the first direction, and the positioning block is abutted to the limiting jig.

9. The breaking-off device of claim 8, wherein the telescoping mechanism comprises:

a first slider connected to the slide plate;

the second floating block is connected with the lifting driving piece;

An elastic member disposed between the first slider and the second slider; wherein,

The lifting driving piece is used for driving the second floating block to move along the first direction, so that the second floating block compresses the elastic piece to push the first floating block and the sliding plate to move along the first direction.

10. The breaking-off device of claim 8, further comprising an adjusting assembly, wherein the adjusting assembly comprises a fixed seat and a sliding block, wherein the fixed seat is connected with the sliding plate, the sliding block is slidingly connected with the fixed seat along a second direction perpendicular to the first direction, and the mounting frame is fixedly connected with the sliding block.
