This invention involves a type of connecting device for handle operation, including front node handle, rear node handle and locking pin. The external circle of front node handle (1) vertical to the axis is equipped with two holes of different sizes on the same axis; the external circle (11) of rear node handle is in clearance fit with inner hole (10) of the front node handle, which is provided with a pair of holes of the same axis at the junction of both front and rear node handles for the purpose of realizing the inserted locking of the rear end (7) of the pin to form the moving pair (12) and (13) in clearance fit with the axle and hole; front part (4) of the pin is inserted into the small hole on the external column of front node handle (1) to form the moving pair (8) in clearance fit between hole and axle, which penetrates through the inner hole (5) of the compressed spring to insert the sliding nut (6) into the coordinating hole on the external column of front node handle to form moving pair (9); use the screw pair to screw sliding nut (6) on the front part of the pin to realize combined connection, so as to ensure the reliable operation of handle, and facilitate the storage after use.
