Claims (1)

[Scope of Claim for Utility Model Registration] A plurality of electrode frames equipped with upper and lower opposed electrodes of a wire mesh welding machine for reinforcing bars are arranged in a row so as to be able to slide along the front surface of a horizontal beam, and the electrode frames can be attached to each other as necessary. In the positioning device for correcting and fixing the spacing, the cross section is V
a horizontal concave groove in the shape of or inverted trapezoid; a restraining arm that protrudes rearward from the electrode frame along the lower surface of the horizontal beam, and whose tips become left and right vertical plates that stand up behind the concave groove; The base is pivoted between the plates,
The head fits into the groove above, and is pivotally supported by an eccentric shaft between the swinging stopper piece that moves away and the left and right vertical plates, and by rotating the attached handle, the head of the stopper can be pressed onto the groove with its outer periphery. 1. A positioning device for a wire mesh welding electrode for reinforcing bars, characterized by comprising: an eccentric cam adapted to be loosened or loosened;
