Abstract:
1. A hand power tool comprising: a tool bit; a tool housing in which a drum-type tool change magazine is disposed, the magazine having at least one tool chamber configured to store the tool bit; a tool receiver arranged on the tool housing and configured to receive the tool bit, the tool receiver having an inner receiver, wherein the at least one tool chamber is configured to be aligned so as to be flush with the inner receiver to enable the tool bit to slide from the at least one tool chamber into the inner receiver or from the inner receiver into the at least one tool chamber; and a braking device configured to brake the tool bit as the tool bit slides from the at least one tool chamber into the inner receiver, wherein: the braking device has a braking member that is sleeved onto the tool receiver and that has a hook-shaped end region, the hook-shaped end region has an at least approximately annular friction region configured to contact the tool bit, the friction region configured to deform to generate a braking frictional force on the tool bit as the tool bit slides into the inner receiver, the inner receiver has a longitudinal axis, a proximal axial end proximal to the at least one tool chamber, and a distal axial end spaced along the longitudinal axis from the proximal axial end and distal from the at least one tool chamber, and the braking member is located at the distal axial end of the inner receiver.
