Abstract

A reinforcing bar binding machine includes a first movable gripping member that is displaced in a direction to come in contact with and separate from one side of a fixed gripping member. A second movable gripping member is displaced in a direction to come in contact with and separate from the other side of the fixed gripping member; and a bending portion brings the first movable gripping member and the second movable gripping member into and out of contact with the fixed gripping member. The fixed gripping member includes a shaft that rotatably supports the first movable gripping member and the second movable gripping member. In addition, the bending portion includes an opening and closing pin that pushes an opening and closing guide hole provided in the first movable gripping member and an opening and closing guide hole provided in the second movable gripping member.

First claim

1 - 26 . (canceled)

27 . A binding machine comprising:
a housing that is configured to house a wire; a wire feeding unit that is configured to feed the wire housed in the housing; a curl guide that is configured to wind the wire fed from the wire feeding unit around a binding object in a loop; and a binding unit that is configured to grip and twist the wire wound around the binding object, wherein the binding unit includes: a pair of movable gripping members each of which includes one end side and an another end side, wherein the one end sides are movable toward and away from each other; and a fixed griping member, wherein the pair of movable gripping members are provided on both sides of the fixed gripping member via the fixed gripping member, wherein one of the pair of movable gripping members is a first movable gripping member which includes a protrusion protruding toward the fixed gripping member, on a surface facing the fixed gripping member, and wherein the fixed gripping member includes a recess into which the protrusion is inserted, on a surface facing the first movable gripping member.

28 . The binding machine according to claim 27 ,
wherein the another end sides are rotatably supported on a shaft extending in a first direction such that the one end sides are movable toward and away from each other.

29 . The binding machine according to claim 28 ,
wherein the binding unit includes: a moving member that is fitted to the pair of movable gripping members and that is movable in a second direction orthogonal to the first direction, wherein the first gripping member includes a first fitting portion such that the moving member is fitted to the first fitting portion and the fitted moving member is movable in the second direction, and wherein the other one of the pair of movable gripping member is a second movable gripping member which includes a second fitting portion such that the moving member is fitted to the second fitting portion and the fitted moving member is movable in the second direction.

30 . The binding machine according to claim 29 ,
wherein the fixed gripping member includes a third fitting portion which is movable in the second direction by fitting the moving member fitted to the first and second fitting portions.

31 . The binding machine according to claim 28 ,
wherein the shaft is provided on the fixed gripping member.

32 . The binding machine according to claim 31 ,
wherein the shaft is provided on an extended line of a moving path of the moving member.
