Abstract： |
The present invention relates to a body-separated type one-way bolt fastener, belonging to the field of mechanical assembly technology. Said bolt body is composed of three portions, including two side bar bodies and one intermediate bar body, said three portions can be combined into a bolt whole body. The outer profile of cross-section of main body portion of every side bar body is equipped with a section of minor arc, said curved face has screw threads. Said intermediate bar body is mainly used for preventing side bar body from falling and has anti-drawing measure.
