Hand-held power tool

A hand-held power tool, comprising:

• a drive unit;
• an output shaft at which a tool holder is formed, the tool holder including an internal polygonal holder for connection to a first insertion tool and an external polygonal holder for connection to a second insertion tool, a locking unit configured for locking the first insertion tool being assigned to the tool holder;
• and
• a striking mechanism connected to a drive element, wherein the striking mechanism encompasses an impact body which is configured to impart an impact to the output shaft;
• wherein the locking unit includes at least one locking element, the locking element including at least one contact surface which axially supports the second insertion tool,
• wherein the locking unit includes at least one actuating element which accommodates the locking element in a form-locked manner,
• wherein the actuating element encompasses at least one first internal holder for accommodating the locking element, a second internal holder for accommodating a support element, and a third internal holder for accommodating a fastening element,
• wherein the actuating element includes an at least partially circumferential collar, and the locking element includes an at least partially circumferential shoulder, the shoulder resting axially against the collar,
• wherein the actuating element at least partially accommodates the fastening element to form a clamping connection, the fastening element clamping the support element onto the actuating element and fixing the locking element,
• wherein at least one section of the locking element at least partially projects over the actuating element in an axial direction pointing away from the drive unit;
• wherein, in a connected state, the second insertion tool rests directly against the at least one contact surface of the locking element.
