A rebar binding machine comprises a curl guide that causes a wire to curl, a torsion part including a torsion shaft for twisting the curled wire, and a pair of grips that can be grasped by an operator. The grips are provided to the two axial sides of the torsion shaft as viewed from the operator side when the operator grasps the grips to perform an operation, and it is possible to change the height of the grips in the axial direction of the torsion shaft.

A reinforcing bar binding machine capable of reliably performing a wire gripping operation includes a first movable gripping member that is displaced in a direction to contact with and separate from one side of a fixed gripping member and a second movable gripping member that is displaced in a direction to contact with and separate from the other side of the fixed gripping member. 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. Further, 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.

A slide block-based positioning mechanism and an automatic tie tool having the same. The slide block-based positioning mechanism includes a slide block and a guide rail. The slide block fits the guide rail. The guide rail limits five degrees of freedom of the slide block. The slide block slides in a length direction of the guide rail. A head portion of a tie is arranged at a predetermined position at the slide block. The slide block pushes the tie from the predetermined position to a tie installation position.

In an approach to a one-handed removable component (RC) extraction, a fixed length strap and a variable length strap, based on a configurable diameter loop in the variable length strap, are attached to each other. The variable length loop passes through the RC extraction handle and encircles a RC release lever. The fixed length strap is attached to the RC extraction handle. The loop diameter is calibrated such that pulling on the fixed length strap first applies force to the variable length loop engaging the release handle, in a direction perpendicular to the applied force, without damage before transferring force to the fixed length strap to extract the RC.
