Abstract
A return transmission of nailing rod for electric nail gun is disclosed, comprising a pulley assembly and a return elastic component configured in a gun body frame. The pulley assembly includes a towing rope, a movable pulley that guides the towing rope. A guiding holder is provided for pivoting the movable pulley. When the nailing rod moves downward along a nailing stroke to shoot the nail, the towing rope can tow the movable pulley and drive the guiding holder to move an action stroke in a way to store the elastic potential energy of the return elastic component. After nailing, the return elastic component will drive the guiding holder in a way to release the elastic potential energy, so that the guiding holder can move along the action stroke back to its original position, and the guiding holder will tow the towing rope through the movable pulley, so as to drive the nailing rod to move along the nailing stroke back to its original position. In this way, the load of the return elastic component can be reduced.
