Abstract

The invention discloses an expansion pin. The expansion pin comprises a longitudinal joint and an installing hole which are formed on an expansion pin body, wherein the expansion pin body is provided with a cavity; the outward side of the cavity is provided with an opening; the cavity is communicated with the installing hole; the top surface of the cavity is provided with an assembling hole whichis communicated with the cavity; the assembling hole and the installing hole are arranged coaxially; the longitudinal joint is formed obliquely and / or in parallel along the axial direction of the expansion pin body and is formed continuously and / or discontinuously; and the cross section of the cavity is annular. The expansion pin and a connecting piece thereof comprise the expansion pin and the connecting piece, wherein the connecting piece is provided with more than one pin which is inserted into the cavity; and the pins are provided with positioning holes which are coaxial with the assembling hole and the installing hole. The expansion pin and the connecting piece thereof have the characteristics of simple and reasonable structure, flexible operation, difficult falling, easy installation, wide application range and the like.

Description

Technical field [0001] The invention relates to an expansion pin and its connecting piece. Background technique [0002] Common expansion screws with expansion pins and connectors are separated from each other, and the expansion screws with expansion pins and connectors placed in the same packaging box or bag are also separated from each other, if they are in transit or during installation If the expansion screws with expansion pins in the packaging box or packaging bag are dropped or missing, it will cause unnecessary troubles to the installation of connectors and other parts. Summary of the invention [0003] The purpose of the present invention is to provide an expansion pin and its connector with simple and reasonable structure, flexible operation, not easy to fall off, easy to install, and wide application range, so as to overcome the deficiencies in the prior art. [0004] An expansion pin designed for this purpose, including a longitudinal slit and a mounting hole arranged o...
