Abstract

An object of the invention it is a retainer clip for securing the rotatable elements from falling out of a support block, especially it regards the cutting tools of the mechanical coal miner. The cutting tool retainer is formed of the material with a uniform cross-sectional area, with the two end portions not touching each other, in such a way that the new-created protrusions and recesses are joining together forming the open figure symmetrical along a vertical axis, whereby the protrusions extend beyond the diameter of a cylindrical shank. The cutting tool retainer (1) after installing it engages the bottom portion of the recess (11) in a cylindrical shank (12) of a cutting tool (14) with its inner surface as well as the outer surface. The end portions (2) and (2') of the retainer, directed inwardly towards the figure of retainer (1), are turning into the outward slides (3) and (3') which, in turn, through the bends (4) and (4') are turning into the inward slides (5) and (5'). The inward slides (5) and (5') through the protrusions of end portions (6) and (6') are turning into the arms (7) and (7'), which through the side protrusions (8) and (8') and recesses (9) and (9') are connecting each other with the central protrusion (10). The distance (d) between the apexes of the bends (4) and (4') and the distance (e) between the apexes of recesses (9) and (9') are less than the bottom diameter of the recess (11) in a cylindrical shank (12) of a cutting tool (14).
