The invention relates to a screw driver for an inner profile (10), which comprises a shaft (12) and an outer profile head (18) which is embodied in a manner which corresponds to the inner profile recess (14) of the inner profile screw. The distal area of the shaft, which comprises an outer profile head, is embodied in a split manner and a bushing (16) receives the shaft and can be displaced in relation therewith. At least one part of the shaft, which comprises a gap, is provided with an oblique contact member and the bushing is provided with a contact ring which acts upon the oblique contact member(s). When the bushing is displaced in relation to the shaft, the part of the shaft which comprises the oblique contact member, is cut and pulled away from the other part, by clamping the inner profile recess with the outer profile head. |
