When the wire 3 is conveyed forward, the first pneumatic clamping jaw 11 first clamps the wire 3, and then the first front and rear telescopic cylinder 10 contracts, so that the wire 3 moves forward by a fixed length distance. When carrying wire rod 3 backward, first pneumatic clamping jaw 11 is to wire rod 3 centre gripping, and first front and back telescopic cylinder 10 stretches out afterwards, makes wire rod 3 move fixed length distance backward then.
