Bolt thread rolling magnetic attraction auxiliary frame

The invention relates to an auxiliary frame, in particular to a bolt thread rolling magnetic attraction auxiliary frame. The bolt thread rolling magnetic attraction auxiliary frame can replace a worker to limit a bolt, the hand can be prevented from being injured by a thread rolling machine, and thread rolling is prevented from being affected by bolt position deviation. The bolt thread rolling magnetic attraction auxiliary frame comprises a frame body and a fixed plate, supporting legs are fixedly connected to the outer two sides of the frame body symmetrically, a discharging opening is formedin one side, the fixed plate is fixedly connected to the position, away from the supporting legs, between the inner two sides of the frame body, a bolt is put into the frame body, a strong magnet attracts the bolt and fixes the bolt on a hollow cylinder, a push rod is pushed to move rightwards, the hollow cylinder drives the bolt to move rightwards to the thread rolling position of the thread rolling machine, the thread
