As the further preferred technical scheme of this embodiment, spacing subassembly includes the movable groove 27 that sets up in the 3 tip of reinforcing bar, the activity is provided with two trigger block 29 that connect through thrust spring 28 in the movable groove 27, trigger block 29 is kept away from thrust spring 28 one end and is stretched out 3 lateral walls of reinforcing bar and be provided with the slope terminal surface, fixedly connected with coupler body 30 on the trigger block 29, sliding sleeve 12 inner wall is provided with and hooks body 30 assorted hook groove 31, specifically, movable groove 27 sets up in the cone 3.1 of 3 tips of reinforcing bar, trigger block 29 sets up the tip of slope terminal surface and stretches out the setting of cone 3.1 lateral wall. In practical use, when the abutting body 13 abuts against the sliding sleeve 12, the cone 3.1 can be inserted into the abutting hole 14, and then the inner wall of the abutting hole 14 can be attached to the outer side wall of the cone 3.1, so that the inclined end face of the trigger block 29 can be extruded, the trigger block 29 retracts towards the movable groove 27, the thrust spring 28 deforms and compresses, and meanwhile, the retraction of the trigger block 29 drives the hook body 30 to retract towards the inside of the steel bar 3, and then the hook body leaves the hook groove 31 on the inner wall of the sliding sleeve 12, so that the limit of the sliding sleeve 12 is cancelled, and the sliding sleeve 12 can move relative to the steel bar 3 at the moment so as to trigger the second unidirectional feeding assembly.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
