Abstract
A rebar tying machine comprising a tying machine main body (1) and a steel wire winding assembly (2) mounted in the main body, a steel wire cutting off mechanism (3) is further mounted in the main body and comprises a transmission device (31) and a wire discharging block (32), the steel wire winding assembly comprises a winding mechanism (21), a driving device (22) for driving the winding mechanism and a locking device for locking the winding mechanism, an advance/retreat locating slot (211) and a rotating cam slot which are communicated with each other are arranged on the winding mechanism, an anti-rotation fixing pin (231) in the locking device moves axially in the advance/retreat locating slot, and the anti-rotation fixed pin slides in the rotating cam slot along the circumferential direction. The rebar tying machine has the advantageous effect that: the anti-rotation fixed pin moves axially in the advance/retreat locating slot and slides in the rotating cam slot along the circumferential direction, and the sidewall of the rotating cam slot extends along the axial direction of a sleeve (216) to form a chamfer structure, thus preventing the tying machine from locking and further …
