The invention discloses a steel wire threaded sleeve installation tool free of installation handles. The steel wire threaded sleeve installation tool comprises a mandrel. A thread matched with an internal thread of a steel wire threaded sleeve free of installation handles is arranged on the outer surface of the mandrel. The mandrel is provided with an axial hole. An upper through groove and a lower through groove which are opposite are formed in the portion, at one end of the mandrel, of the hole wall. The upper end face of the upper portion of a clamping head is a conical face formed by a left inclined face and a right inclined face. A cone is arranged on the rear portion of the left inclined face and matched with an acute angle groove in the outer end of a clamping groove in one end of the steel wire threaded sleeve free of installation handles. A clamping head base is arranged on the lower portion of the clamping head. The lower surface of the clamping head base is a plane. The lower portion of a spring supporting block is matched with the lower through groove of the end of the mandrel. A spring base is arranged on the upper portion of the spring supporting block. The upper surface of the spring base is a plane. A spring is arranged between the clamping head base and the spring base. The steel wire threaded sleeve installation tool has the remarkable advantages that materials are saved for the steel wire threaded sleeve and the installation efficiency is high.
Description
[0001] Technical field: [0002] The invention relates to a tool for installing a wire screw insert, in particular to a tool for installing a steel wire screw insert without a mounting handle. [0003] Background technique: [0004] There is a mounting handle at the end of the traditional wire thread insert, and the tool for installing the wire thread insert can be easily installed into the base hole of the wire thread insert by using this installation handle. The installation handle is removed, which not only wastes materials, but also reduces installation efficiency. For this reason, a wire thread sleeve without a mounting handle is designed. The structure of this wire thread sleeve is that a card slot is provided on the inner side of the end of the wire thread sleeve. To use this card slot, it is necessary to provide an installation tool for installation. . [0005] Invention content: [0006] The object of the present invention is to provide an installation tool for a st...
