    摘要： The portable power tool according to the invention has a tool receptacle (2) for receiving a tool (3), a motor (4), at least one switchable transmission stage (10), and a slider (18). The transmission stage (10) has a transmission element (15) that is movable in a switching direction (31) and has a toothing (16) which is engaged with a corresponding toothing (17) in a first transmission position and disengaged from the corresponding toothing (17) in a second transmission position. The slider (18) is displaceable in the switching direction (31) by a user between at least one first switching position and a second switching position, wherein the first switching position is assigned to the first transmission position and the second switching position is assigned to the second transmission position. The slider (18) has a finger (32). A coupling device (41) has a slide (21) that is movable in the switching direction (31) and a catch (35) for locking the slide (21) to a housing (7). The slide (21) is connected to the movable transmission element (15) and the catch (35) is locked in place in the first transmission position and the second transmission position and is not locked in place in positions between the first transmission position and the second transmission position. A spring element (42) has a resilient first portion (25; 44) and a resilient second portion (26; 44), wherein the two portions (25, 26; 43, 44) each have an end (27, 28; 45, 46) that is fastened to the slide (21) and an end (29, 30; 47, 48) that is movable with respect to the slide (21). The finger (32) is arranged along the switching axis (20) between the portions (25, 26; 43, 44).

    摘要： A hand-held power tool (1) according to the invention has a tool holder (2) for holding a tool, an electric motor (3) and a slip clutch (7) coupling the tool holder (2) to the electric motor (3). The slip clutch (7) has a drum (13) that can rotate about a rotational axis (15), a wheel (12) that can rotate about the rotational axis (15) in the drum (13), and one or more blocking bodies (14) that are spring-loaded in the radial direction and coupling the wheel (12) to the drum (13). The drum (13) has a tubular inner surface (20) with multiple cams (22) protruding towards a rotational axis (15). The wheel (12) has multiple pockets (18) which are open in the direction of the running surface (20), and in which the blocking bodies (14) are loosely inserted. Each blocking body (14) has two sliding regions (29), which both contact the running surface (20) in a linear manner, and two support regions (25, 26) of which, depending on the rotational direction (17) of the wheel (12), the respective forward support region (25) is at a distance to the wheel (12), and the respective rear support region (26) contacts the wheel (12) in a linear manner.

    摘要： The portable power tool (1) according to the invention has a tool holder (2) for holding a tool (4) on a working axis (11), a motor (5) and a pneumatic percussion mechanism (6). A drive output shaft (7) is coupled to the tool holder (2) in order to rotate the tool about the working axis (11). A friction clutch (24) is arranged in the drive train between the motor (5) and the drive output shaft (7). The friction clutch (24) has a disc (25) on the drive-input side and a disc (26) on the drive-output side. The disc (25) on the drive-input side has, on a driving annular surface (28) bearing against the disc (26) on the drive-output side, first sectors (33) with a high coefficient of friction and second sectors (34) with a low coefficient of friction. The disc (26) on the drive-output side has, on the driven annular surface (29) bearing against the driving annular surface (28), third sectors (35) with a high coefficient of friction and fourth sectors (36) with a low coefficient of friction.
