Abstract

A sleeve retainer for use in an extension rod drilling machine when uncoupling a drill rod from the drill motor drive shaft comprises a frame (8) mountable on the feeding beam (2) of the machine, two jaw arms (12, 13) mounted coaxially and pivotably on the frame (8) and provided with jaws (14) facing each other, and a pressure-fluid operated actuating means (15) which pivots the jaw arms (12, 13) to a gripping position, in which the jaws (14) would be pressed against the connection sleeve (6) of the drill rod, and to an open position, in which the jaws (14) are displaced away from each other (Fig. 4). The actuating means is connected to the jaw arms (12, 13) so that the jaw arms (12, 13) and the actuating means (15) form a unit which is freely pivotable around the pivot shaft (11) of the jaw arms (12, 13) with respect to the frame (8). <IMAGE>
