摘要

(57) Abstract Topic To output torque securely and racing phenomenon of transmissionOffer of structure of the jumping movable head of the electromotive stock tool which is prevented. Solutions It was provided in the chuck of the electromotive stock toolOn the top of the jumping movable head and the like widely the square pillar body being provided in distance, it is hardExtending from the square hole of the fixed vessel, it receives and contacts all surface on the one bottomWhen it does, liking to output power completely when building, the springWith the pressure nut being joint, pressure welding doing in the area of the square pillar body, adding powerDestruction and the normal torque coming out of the receiving piece which is formed by unevenTo prevent the influence to power, at the same time, the said square pillar body the side edge of the jumping movable headFrom extending a little, in inserting and positioning to the groove of the fixed vessel the advantageWith it features that it is done.
