ABSTRACT:
The invention concerns a retaining device for an angled head (10, 11) that is driven by a drive (1) especially a drilling gun, in which the drive unit (1) has a receiving connector (2) to receive the angled head (10, 11). To allow adjustment of the angular position of the angled head with respect to the drive unit, a socket (31) that can be screwed onto threads (33) of the receiving connector (2) is provided to receive the angled head (10, 11). Pins (21) which can be displaced axially in order to retain or release balls (25) are provided in the socket (31). The receiving connector (2) has on its outer surface a plurality of lengthwise grooves (29) in which the balls are held (25). When the pins (21) are displaced axially the balls (25) are released, so that the socket (31) can rotate relative to the receiving connector (2) until the balls (25) engage in corresponding lengthwise grooves ( 29) and are retained by the pins.
