Abstract
The invention relates to a tool, especially a screwing tool having a handle with a chuck, and a blade, especially a screwdriver blade, that can be inserted into an insertion opening of the chuck. The blade inserted into the insertion opening is held by a detent of the chuck, said detent being displaced from a detent position to a release position by actuating a trigger. The inventive tool is characterized in that the detent comprises a detent projection which is located on a spring arm that extends in the axial direction of the insertion opening and on the periphery thereof. Said spring arm is displaced by a control element of the trigger that can be displaced in the axial direction from the detent position to the release position. The insertion opening is configured by an insertion cylinder located in a cavity of the handle. The insertion cylinder is produced from plastic and the spring arm is associated with the insertion cylinder in order to form a single part consisting of the same material.
