Abstract

A chuck for drilling and chiseling tools and including a receiving sleeve at least one through-opening formed in a sleeve wall at least one locking member supported for a limited pivotal movement about a pivot axis, which extends substantially perpendicular to a longitudinal axis of the receiving sleeve, and projecting at least partially into the through-opening (12) of the sleeve with the locking member (6) extending in its locking position through the through-opening (12) into a receiving sleeve inferior, a guide ring surrounding the receiving sleeve and at least partially overlapping the locking member (6) in its locking position, preventing the locking member (6) from pivoting into its release position and an actuation sleeve (7) displaceable in a direction opposite to an operational direction of the tool against a spring-biasing force for enabling pivoting of the locking member (6) into the release position, with the locking member (6) being pivotally connected with the actuation sleeve (7).
