Abstract
A hand-held power tool includes a tool receiver with a tubular tool holder and an assigned locking device. The assigned locking device includes a locking element configured to lock an insert tool in the tubular tool holder, a pressure sleeve that is spring-loaded via an assigned spring element, and a stop sleeve, the spring-loaded pressure sleeve configured to press the locking element in a locking position against the stop sleeve. The tubular tool holder includes at least one recess in which the locking element in the locking position is located, at least portionally. The stop sleeve has, on its inner circumference, at least one contact surface that is matched to an outer contour of the locking element such that a first surface contact between the at least one contact surface and the locking element is established in the locking position.
