A binding machine includes a first main body, a second main body and a bridge part. The first main body houses a binding part which twists a wire and a driving part which drives the binding part. The second main body is provided with a handle part including an operation trigger. The bridge part connects the first main body and the second main body to each other.

A rebar tying tool may include a holder, a stopper, a driving roller, and a driven roller. The stopper may be configured to switch between a prohibiting state in which the stopper prohibits a reel from detaching from the holder and an allowing state in which the stopper allows the reel to detach from the holder. The driving roller may be configured to rotate. The driven roller may be configured to switch between a clamped state and a non-clamped state, the wire may be clamped between the driving roller and the driven roller when the driven roller is in the clamped state, and the wire may not be clamped between the driving roller and the driven roller when the driven roller is in the non-clamped state. The driven roller may be in the non-clamped state at all times while the stopper is in the allowing state.

A binding machine includes a wire feeding unit, a curl forming unit, a cutting unit, a binding unit, and a transmission unit that transmits movement of the binding unit to the cutting unit. The binding unit includes a locking member that locks a wire, a sleeve that actuates the locking member, and a rotary shaft that actuates the sleeve. The transmission unit includes a displacement member to be displaced by movement of the sleeve, and a transmission member that transmits movement of the displacement member to the cutting unit. The cutting unit includes a movable blade part connected to the transmission member. The displacement member switches an amount of movement of the movable blade part and a force that can be generated by the movable blade part, within a moving range of the movable blade part.

It Provids a reinforcing bar binding machine that reduces restrictions on arrangement of a magazine in which a wire is housed.

A reinforcing bar binding machine (1A) includes a magazine (2A) in which a wire (W) is housed, a curl guide unit (5A) that winds the wire (W) around a reinforcing bar (S), a wire feeding unit (3A) that feeds the wire (W), and a binding unit (7A) that twists crossing portions between one end and the other end of the wire (W) wound around the reinforcing bar (5). The wire feeding unit (3A) is configured such that a second displacement member (36) for displacing a second feed gear (30R) is located behind a second feed gear (30L) and provided between the second feed gear (30L) and a handle portion (11A).

A binding machine includes: a holding portion configured to hold a tip end side of a cured wire rod; a feed unit configured to hold a base end side of the wire rod, the tip end side of which is held by the holding portion, such that the base end side of the wire rod is able to be fed out; a twisting unit configured to twist the wire rod; and a control unit configured to control the feed unit and the twisting unit. The control unit is configured to control the feed unit to feed the wire rod when detecting a first signal, and is configured to control the twisting unit to twist the wire rod when detecting a second signal.

A binding machine includes: a wire feeding unit configured to feed a wire; a curl forming unit configured to form a path along which the wire fed by the wire feeding unit is to be wound around a to-be-bound object; a butting part against which the to-be-bound object is to be butted; a cutting unit configured to cut the wire wound on the to-be-bound object; a binding unit configured to twist the wire wound on the to-be-bound object and cut by the cutting unit; and a tension applying part configured to apply tension to the wire to be cut at the cutting unit with a force higher than a force applied in a loosening direction of the wire wound on the to-be-bound object.

It provides a reinforcing bar binding machine which reduces restrictions on a moving direction of the reinforcing bar binding machine in an operation of pulling out a reinforcing bar bound with a wire. A reinforcing bar binding machine (1A) includes a curl guide unit (5A) that winds a wire (W) around a reinforcing bar (S), a wire feeding unit (3A) that feeds the wire (W), and a binding unit (7A) that twists crossing portions between one end and the other end of the wire (W) wound around the reinforcing bar (S). The curl guide unit (5A) includes a first guide unit (50) that curls the wire (W) fed by the feeding unit (3A) and a second guide unit (51) that guides the wire (W) fed from the first guide unit (50) to the binding unit (7A), and the second guide unit (51) includes a fixed guide unit (54) that restricts a position in a radial direction of the wire (W) wound around the reinforcing bar (S) and a movable guide unit (55) that restricts a position in an axial direction of the wire (W) wound around the reinforcing bar (S).

A binding machine includes a wire feeding unit configured to feed a wire to be wound on an object to be bound and a binding unit configured to twist the wire wound on the object to be bound. The wire feeding unit includes a pair of feeding members configured to sandwich the wire between the pair of feeding members and to feed the wire by a rotating operation, a wire feeding drive unit connected to one feeding member and configured to rotatively drive the one feeding member, and a load reducing part configured to reduce or remove a load, which is to be applied to the wire via the one feeding member, of the wire feeding drive unit.

A binding machine includes a first guide having an introduction part into which the wire to be fed by the wire feeding unit is to be introduced, and configured to curl the wire introduced from the introduction part, a second guide configured to guide the wire delivered from the first guide toward the binding unit, a main body part having one end portion at which the first guide and the second guide are provided, and, an entry regulation part provided in the main body part, provided at one side of the introduction part of the first guide at a downstream side of the binding unit with respect to a feeding direction of the wire to be fed toward the first guide by the wire feeding unit, and configured to prevent the wire from entering into one side of the introduction part of the first guide.

A reinforcing bar binding machine includes a magazine in which two wires are housed in a drawable manner; a curl guide unit that winds the juxtaposed wires around the reinforcing bars and a wire feeding unit that winds the wires around the reinforcing bars with the curl guide unit in an operation of juxtaposing and feeding the wires so that the wires are wound around the reinforcing bars. In addition, the binding machine includes a binding unit that twists crossing portions of one end side and the other end side of each of the wires wound around the reinforcing bars. The binding unit further includes a bending portion that bends the one end side and the other end side of each of the wires, which are wound around the reinforcing bars, toward the reinforcing bars.
