Abstract

A rod body with lock and pivot functions comprises an outer rod and an inner rod, which is installed inside the outer rod. The sequential operation steps of the rod body are as follows: cut a hole on the target subject using drilling tools wherein the size of the hole allows the outer rod to insert; pull the outer rod upward by rotating the inner rod to cause one or more partial sessions of the outer rod to be deformed, so that the rod body of the present invention is firmly installed onto the target object. Subsequently, various elements of different functions can be pivoted to the rod body of the present invention through the evolving section of the inner rod, having screw threads or a screw rod thereon and allowing the present invention to be connected to additional construction elements of different functions during the operation. Therefore, the present invention meets the required features of patentability of inventions of “creativity” and “non-obviousness”.
