Abstract
A quick release apparatus includes a tightening shaft including a screw portion at one end thereof, a tightening control lever mounted on the other end of the tightening shaft, and a clamp mounted on the screw portion. The clamp includes a nut meshed with the screw portion, a contact element axially movable relative to the nut and including a surface for contacting an object, and an elastic element disposed between the nut and the contact element. The contact element and nut are disposed coaxially with the tightening shaft to be rotatable relative to each other around the tightening shaft. This quick release apparatus further includes a displacement amplifying link mechanism such as a single lever mechanism for amplifying a relative axial displacement between the nut and contact element. A subtle relative displacement between the nut and contact element is presented as an enlarged displacement for observation purposes.
