Abstract
An electric screwdriver is disclosed. The screwdriver has a spindle, a locking body, a radial stop, a strap, and a spring. The spindle defines a receiving area and an oblong hole which is open into the receiving area in a radial direction. The locking body is disposed in the oblong hole, where the locking body is protrudable into the receiving area. The radial stop is engageable with the locking body where, when the radial stop engages with the locking body, the locking body protrudes into the receiving area. A first end of the strap engages behind the locking body on a drive end. The spring is disposed between a second end of the strap and the radial stop.

An electric screwdriver, comprising:
- a spindle, wherein the spindle defines a receiving area which is open on an output end and is oriented along a working axis for receiving a screwdriver bit in an insertion direction and wherein the spindle defines a hole which extends oblong in a longitudinal direction of the spindle and which is open into the receiving area in a radial direction;
- a locking body disposed in the hole, wherein the locking body is movable in the hole in the longitudinal direction, and wherein the locking body is protrudable into the receiving area;
- a radial stop engageable with the locking body, wherein when the radial stop engages with the locking body the locking body protrudes into the receiving area;
- a strap, wherein a first end of the strap engages behind the locking body on a drive end, wherein the drive end is opposite from the open output end of the spindle, and wherein the strap is axially movable;
- and
- a spring, wherein the spring is disposed between a second end of the strap and the radial stop.
