A manipulation cart system for manipulating a tool described herein includes a chassis subsystem, a locomotion subsystem, at least one manipulation subsystem, at least one attachment subsystem, and at least one control subsystem. The locomotion subsystem may include a turn pivot. The at least one manipulation subsystem may include at least one tilting subsystem. Preferably the cart system at least partially relieves the physical demands of manipulating the tool and at least partially protects from stress-induced injuries associated with manipulating the tool.

A hand-held power tool includes a tool holder for holding a tool on a working axis, a pneumatic striking mechanism for striking the tool, and an absorber, which includes a bending spring, situated transversely to the working axis, and a mass body. A countershaft is driven by the motor around a rotation axis which runs in parallel to the working axis. A wobble drive for driving the pneumatic striking mechanism is situated on the countershaft. In addition, a cam disk is situated on the countershaft and includes a cam which projects in a start-up direction which runs in parallel to the working axis. The bending spring includes a counterpiece provided relative to the cam. The cam, which abuts the counterpiece, pretensions the bending spring in the start-up direction.

A power tool includes a motor, a housing, a battery holder and a cushion. The battery holder is held by the housing to be movable at least in a first direction relative to the housing. The battery holder is configured to removably receive a battery for supplying electric power to the motor. The cushion is held by the housing such that the first direction intersects the cushion. When the battery is attached to the battery holder, the cushion is directly or indirectly disposed between the battery and the housing.

A hand-held power tool drive device includes at least one wobble drive unit that has at least one rotatably mounted drive element, with at least one wobble unit positioned on the at least one drive element. The drive device also includes at least one counterweight unit that has at least one movably mounted compensating element configured to be driven by the at least one wobble unit. The at least one wobble unit includes at least one force application point that is configured to drive the at least one compensating element. An axis extending through a rotational axis of the at least one drive element and the at least one force application point encloses an angle of between 0° and 135° with a wobble element longitudinal axis of a wobble element of the at least one wobble unit.

An impact drill includes an output shaft capable of rotating around a first axis and moving along the first axis, a housing, a first impact block fixedly connected to the output shaft, a second impact block, a stopping element for stopping the output shaft from moving backward, and a movable element mounted on the housing. The housing is formed with a through hole for accommodating the movable element. The through hole passes through the housing in a first line and the movable element is capable of moving to a first position and a second position along the first line. When the movable element moves to the first position, the movable element prevents the output shaft from moving backward. When the movable element moves to the second position, the movable element allows the output shaft to move backward.
