Abstract: A tool quick-release mechanism includes a body having a guiding hole extending along a longitudinal axis, a control hole, and a coupling hole. Each of the control hole and the coupling hole intercommunicates with the guiding hole, extends in a radial direction perpendicular to the longitudinal axis, and extends through a sidewall of the body.

A coupling member is movably received in the coupling hole and is operatively connected to a guiding member movably received in the guiding hole. A biasing member is disposed between the guiding hole and the guiding member. When the control member moves in the control hole, the guiding member is actuated to resist a biasing force of the biasing member, and the coupling member selectively protrudes beyond the coupling hole in response to movement of the guiding member in the guiding hole.
