A striking mechanism includes a working space whose first section is surrounded by a first electromagnet and whose second section is surrounded by a second electromagnet; a striking element that can move along a striking axis inside the working space and that has a magnetizable material; an anvil whose striking surface delimits the working space in the striking direction and which protrudes into the first magnetic coil and which is made of a magnetically soft material. A spring element is provided which exerts a force onto the striking element in every position in the working space in the direction of the anvil.

Striking mechanism and hand-held power tool

A chuck () for a hand-held power tool (), which is connected with a motor-driven spindle () of the power tool for joint rotation therewith, includes a locking device for securing a shaft section of an exchangeable working tool and having a circular cross-section in the chuck () without a possibility of axial displacement and rotation relative to the chuck (), with the locking device having a clamping element () for securing the shaft section (), and an element () for transmitting rotation to the shaft section () and rotationally separated from the clamping element () by a rotary bearing ().

Chuck

A cyclone separator () for use in a suction apparatus () of a hand-held power tool () includes a dirty air inlet (), a suction ventilator () for aspirating, through a suction opening () which is connected with the dirty air inlet (), abrasion particle-carrying suction air, a pure air outlet for letting out purified air, a vortex chamber () arranged between the dirty air inlet () and the pure air outlet, with the dirty air inlet () opening substantially tangentially into the vortex chamber () for generating a swirling stream in a direction toward the pure air extraction element (), a collection chamber (), and particle outlet having at least two particle outlet openings and connecting the vortex chamber with a collection chamber (), with the dirty air inlet opening into the vortex chamber between the two particle outlet openings.
