Abstract
A hand-held power tool includes a tool receptacle with which a tubular tool holder configured to receive an application tool is associated, and a locking device configured to lock the application tool in the tubular tool holder. The locking device locks the application tool in a locking position via at least one locking element in the tubular tool holder. The locking device has a locking sleeve and a pressure ring spring loaded via an associated spring element. The spring-loaded pressure ring is configured to force the locking sleeve into the locking position and, in the locking position, forces the at least one locking element against the tool holder.
