Abstract
A quick release guide sleeve assembly comprises an outer sleeve, an inner sleeve axially slidably received in the outer sleeve and having first and second axial positions with respect to the outer sleeve; and a locking mechanism movably mounted on the outer sleeve for frictionally engaging wall surfaces defining an opening for receiving the outer sleeve. The locking mechanism has a locking position in which at least part of the locking mechanism projects radially outwardly beyond the external circumferential surface of the outer sleeve. The locking mechanism further has a releasing position in which the locking mechanism is in a radially inwardly withdrawn state relative to the circumferential surface of the outer sleeve. The assembly further includes a camming arrangement carried on the inner sleeve for pressing the locking mechanism into the locking position when the inner sleeve is in the first axial position and for allowing the locking mechanism to assume the releasing position when the inner sleeve is in the second axial position. A spring urges the inner sleeve continuously into the first axial position.
