Abstract: An operation-free connection structure includes a main bar, a detent lever, a steel ball, a spring, and an operating member. Within the main bar, an elongated chamber is formed, featuring an elongated first hole and a second hole communicating with the chamber. Within the chamber, the detent lever is positioned and is recessed with a first groove and a second groove, with the first groove having a smaller depth than the second groove. The steel ball is located in the first hole and a spring exerts pressure on both the detent lever and the steel ball. This arrangement allows a portion of the steel ball to be embedded in the first groove while another portion protrudes outwardly from the main bar, and the steel ball can then be compressed and rolled into the second groove, thereby freeing the operation of the operating member from connection to an operating tool.
