After the abutment block 320 pushes the fork 500 to abut against the limiting block 310, the pushing abutment of the unilateral abutment block 320 cannot ensure whether the fork 500 abuts against the limiting block 310 completely, so that the abutment of the fork 500 needs to be adjusted twice by the limiting block 310, in order to solve the problems in the above, the limiting block 310 is movably connected to the base 100, that is, the limiting block 310 can move along the direction of the first supporting seat 210, in order to realize the abutment of the limiting block 310, a fixed block 340 is arranged at one side of the limiting block 310 far away from the first supporting seat 210, and two ends of the fixed block 340 are provided with adjusting members 341 abutting against the limiting block 310, it is to be noted that the adjusting members 341 can be connecting members such as bolts and screws, and the limiting block 310 is pushed against the fork 500 by the adjusting members 341, and the design of the device aims at ensuring that a certain gap is still reserved between the fork 500 and the limiting block 310 when the limiting block 310 is pushed to the limit position by the first driving member 110 for realizing the abutment of the abutment block 310, so that the limiting block 310 can be always fixed to the cutter assembly 500 by the adjusting members 341.
