Abstract: A tool receptacle for a hand-held power tool, in particular for a demolition hammer or chisel hammer, includes—a receptacle element for receiving a tool, and a locking element which for locking the tool in the tool receptacle is mounted so as to be eccentric and rotatable on the receptacle element, wherein the locking element with the aid of rotating the latter about the receptacle element is capable of being moved from an unlocked state in which the tool is retrievable from the receptacle element to a locked state in which the locking element encompasses the tool in a form-fitting manner, and vice versa.

Abstract: An eccentric drive 1 for a portable power tool 2 has a motor 5, an eccentric wheel 6, a linear guide 9, a slide 8 and a connecting rod 7, which has a head 17 suspended on the slide 8 and a second head 15 suspended on the eccentric wheel 6. A bearing bush 16 for the rotatable mounting of the connecting rod 7 is provided at least on one of the two heads 17. The head 15 is composed of an injection molding material. The bearing bush 16 is composed of a fiber composite material, which includes continuous carbon fibers 25 embedded in a thermoplastic matrix.

Abstract: A hand-held percussion power tool includes a pneumatic mechanism (20) having a guide (21) and a striking member reciprocating in the guide (21), and a braking device (30) for the striking member and including at least one braking member for breakingly engaging the striking member and formed as a pivot lever (31) a pivotal movement of which is controlled by the striking member.

Abstract: A percussion mechanism (21; 41) for a percussion power tool includes an impact element (24; 44) reciprocating along a percussion axis (22; 42) of the percussion mechanism (21; 41) and acting on the striker (26, 46). The contact point (27, 47) and counter-contact point (28, 48) are provided between the striker (26, 46) and the impact element (24, 44), with the contact point (27, 47) being formed as an exposed contact point and being arranged outside of the percussion axis (22; 42).

Abstract: A chuck for a rotary-percussion power tool (2) and including a working tool guide (3) for receiving a shank (5) of a working tool, at least one locking member (4) for limiting an axial displacement of the shank (5) within an axial displacement length (X) from opposite sides, and a displaceable, spring-biased stop member (7) cooperating, within the shank displacement length (X), with a power tool side, stop surface (8) of the shank (5).
