Hand-held power tool comprising a locking device

A hand-held power tool, comprising:

• a tool receiver that includes a tubular tool holder configured to lock an insert tool therein by an assigned locking device via at least one locking element, the locking device comprising:
• a pressure sleeve that is spring-loaded via an assigned spring element, and a stop sleeve, the stop sleeve having a contact surface on its inner circumference, and the spring-loaded pressure sleeve pressing the at least one locking element, in a locking position, against the contact surface, wherein:
• the tubular tool holder has at least one recess in which the at least one locking element is at least partially located in the locking position, the at least one recess having a first axial end region, a second axial end region having a ramp-type guideway, and a through portion arranged axially between the first and second axial end regions, the at least one locking element comprises a locking sphere of a predefined diameter, the ramp-type guideway is of a length that is greater than or equal to the predefined diameter, the length measured along a line parallel to a surface of the ramp-type guideway from an outer diameter of the recess at one end of the ramp-type guideway to an inner diameter of the recess at the other end of the ramp-type guideway, and the at least one locking element is displaceable along the ramp-type guideway from the locking position to an unlocking position.
