Abstract
A spindle sleeve (4) is provided for the rotary operation in a tool changing device on a hand-operated machine tool, especially a drill hammer for optional operation with a hammer drill or with another tool. To make rapid tool change possible with a simple design, a locking body (7), which co-rotates with the spindle sleeve (4), is mounted in at least one perforation (6) of the spindle sleeve (4). An adapter (14), on which the corresponding tool can be fixed, can be axially inserted into the spindle sleeve (4) with a guide surface (22, 23), and has depressions (13) for the locking bodies (7) for nonrotatable and axially nondisplaceable connection to the spindle sleeve (4). An outer sleeve (8), which blocks the locking bodies (7) in the depressions (13) in a locking position and radially releases them in its release position, is displaceably arranged on the spindle sleeve (4).
