Abstract

A tool retainer for a percussive tool comprises a bushing (1) for receiving a shank (2) of a working tool (3) having at least one guide recess (7) extending at right angle to its axis in which is installed a cylindrical retainer member (8), a sleeve (5) installed for axial reciprocations on the bushing (1) having at least a pair of guide holes (20) each receiving a respective end of the cylindrical retainer member (8). The guide holes (20) have portions a extending in parallel with the axis of the sleeve (5) which support the ends of the cylindrical retainer member (8) when the sleeve (5) is in one extreme position and inclined portions (b) extending in the direction away from the axis of the sleeve (5) which support the ends of the cylindrical retainer member (8) when the sleeve (5) is in the second extreme position. The inclined portions (b) extend at an acute angle with respect to the axis of the sleeve (5) in the direction of removal of the working tool (3). <IMAGE>
