Quick-release tool connecting rod

A quick-release tool connecting rod, including:

• a rod body, including an inner space extending in an axial direction and a through hole communicated with the inner space;
• a quick-release mechanism, including 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 being movable relative to the rod body in the axial direction to drive the push rod to move between a locking position and a release position;
• and
• a second sleeve member, co-movably sleeved to the first sleeve member, the first sleeve member partially embedded within an inner peripheral wall of the second sleeve member;
• wherein the first sleeve member has a first hardness, the second sleeve member has a second hardness which is smaller than the first hardness;
• the inner peripheral wall of the second sleeve member is urged to deform by an outer peripheral wall of the first sleeve member, and the first sleeve member is non-rotatable relative to the second sleeve member;
• when the push rod is in the locking position, the locking member is radially urged by the push rod and partially protrudes out of the rod body;
• when the push rod is in the release position, the locking member is radially retractable without protruding out of the rod body.
