The operation process of the pick-and-place mechanism 320 is specifically as follows: the worker applies a force to the holding section of the retracting handle 3221 in a direction from the accommodating shell II to the accommodating shell I, the holding section rotates away from the accommodating shell II under the action of the force, the holding section rotates and enables the linkage section to rotate away from the extending hole, the linkage section rotates and enables the retracting rod 3223 to move close to the retracting handle 3221 along the guiding direction of the guide hole 3223a through the pull rod 3222, and therefore the limiting rack 3224 is disengaged from the limiting gear 3226;

another worker moves the second accommodating case away from the first accommodating case, moves the second accommodating case and pulls the cable 310 to move synchronously, so that the cable drum 3227 pays out the cable 310, when the length of the cable 310 matches the width of a bush, the winding and unwinding handle 3221 is released and the elastic force of the return spring 3225 causes the limiting rack 3224 to be reengaged with the limiting gear 3226;

after the bush is cut, the worker disengages the restricting rack 3224 from the restricting gear 3226 again by retracting the handle 3221, and the rope winding drum 3227 retracts the steel rope 310 by the elastic force of the spring 3228.

Preferably, in the process that the steel cable 310 is wound and unwound through the rope winding drum 3227, the steel cable 310 repeatedly contacts with the wall of the first threading hole, and meanwhile, if the axis of the first threading hole is not tangent to the rope winding drum 3227, that is, an included angle exists between the axis of the first threading hole and the rope winding drum 3227, friction between the steel cable 310 and the wall of the first threading hole is large, so that abrasion on the steel cable 310 is large, and service life of the steel cable 310 is affected.

More specifically, in the process of reciprocating the mounting shell 210 along the width direction of the bush, if the mounting shell 210 collides with the first accommodating shell/the second accommodating shell due to misoperation of workers, the trimmer is damaged, and in order to avoid the problem, the buffer springs 3230 are sleeved outside the steel cable 310, the buffer springs 3230 are provided with two groups, one end of one group of the buffer springs 3230 is connected with the first accommodating shell, and one end of the other group of the buffer springs 3230 is connected with the second accommodating shell; during the reciprocating movement of the mounting housing 210, the two sets of buffer springs 3230 can buffer the mounting housing 210 from colliding with the first accommodating housing/the second accommodating housing.
