ABSTRACT:
A fast disassembling joint structure includes a base part and a removable part. One end of the removable part is secured to a desired structure; the other end is a connection arm. The housing has a raceway and a first semi-circular concavity. The movable clamp has an insertion section to engage a recess of the connection arm. The insertion section has a second semi-circular concavity to fit with the first semi-circular concavity so as to pivotally connect with the connection arm. A spring is adapted to provide a push force for the movable clamp. A top cover, secured on the housing, is employed to house the spring and movable clamp inside. A handle of the movable clamp extends out of an opening of the cover so that users can manually control the handle to disassemble the removable part.
