摘要： A quick-release tool connecting rod is provided, including: a rod body, a quick-release mechanism and a second sleeve member. The rod body includes an inner space extending in an axial direction and a through hole communicated with the inner space. The quick-release mechanism includes a push rod received within the inner space, a locking member disposed within the through hole and a first sleeve member sleeved to the rod body. The first sleeve member is movable relative to the rod body in the axial direction to drive the push rod to move. The second sleeve member is co-movably sleeved to the first sleeve member, and the first sleeve member is partially embedded within an inner peripheral wall of the second sleeve member. The first sleeve member has a first hardness, and the second sleeve member has a second hardness which is smaller than the first hardness.

摘要： A fabrication method of a holding sleeve is provided. The holding sleeve is adapted to dispose around a body portion of a main body and can rotate relative to the body portion. A blocking member is disposed in at least one through hole of a first sleeve. A second sleeve is movable relative to and disposed around the first sleeve. The blocking member is controllably pressed by the second sleeve to be partially received in an annular groove of the body portion. An elastic member is disposed around and between the first sleeve the first and second sleeves. Before the second sleeve is mounted to the first sleeve, a part of the elastic member corresponds to the blocking member in a radial direction of the first sleeve and can limit the blocking member to locate in the through hole.
