A second shift groove portion is added, or an additional longitudinal groove is formed in the longitudinal groove. Even if the pin moves to the top, it is prevented from coming off to the side, making it difficult for the pin to come off the retaining groove. . The connecting structure of Prior Art Document 2 is a common operating rod that has a connecting portion that can connect a rod-shaped member to a tip tool and a tip tool. and a fixing portion for locking the end tool, the fixing portion being a series of inclined portions connected in an abacus-like manner. The core part is in contact with the tool tip and slides along the axial direction of the core part. The slide member is configured such that each contact portion of the pressing portion is in the radial direction of the core portion. The tip tool is fastened and fixed by pressing the core part with the tool. The connecting structure of Prior Art Document 3 is such that the tool part is made up of a cylindrical shaft part, a pair of push buttons, and two The connecting fitting has a shaft hole and a pair of notched grooves, and the shaft portion is inserted into the shaft hole. The knob can be gripped to make the latch plate appear and disappear from the recess, and the operating rod and the tip tool can be connected. It is formed so that it can be connected.
