Claims

[Claims for Utility Model Registration] A first shaft for transmitting power, the first shaft rotatably engaged with the left and right side walls, and an opening on the rear side of the first shaft; an arm provided with an elongated hole in the front side wall of the first shaft; a sub-arm provided between the side walls of this arm to be engaged with the first shaft and having one end extending to the opening of the arm; a first control piece that has a portion that closes an opening of the arm formed on the rear side of the first shaft and is movable in the longitudinal direction of the arm by engaging with the first shaft; a biasing member that biases the control piece in a predetermined direction; a substantially concentric groove centered on the first shaft is formed at a position where it engages with the second shaft; a second control piece that is engaged with and movable in the longitudinal direction of the arm;
a second shaft that engages with a second control piece, and by moving the second control piece, the first control piece is moved, thereby allowing or preventing rotation of the sub-arm. An arm selection mechanism for selectively transmitting power applied to the first shaft to the arm.
