ABSTRACT:
An adjustable mechanical screwdriver, having a receiving housing, gear housing and a deflection bevel gear. A small structural size is achieved because the driveshaft protrudes with a bearing shoulder at the drive bevel gear in a direction of the bearing shaft, which is inserted into and rotatably seated in a bearing bore of the bearing shaft. The gear housing having the deflection bevel gear and the power take-off shaft with the power take-off bevel gear is pivotable on the bearing shaft. The receiving housing receives the bearing shaft so that it cannot be rotated.
