Abstract: An electric hand tool guided with both hands has a tool housing, a stationary handle, and an additional movable handle, the additional handle being turnable about a turning axis and being also displaceable longitudinally substantially along the turning axis.

Abstract: A hand machine tool operated with two hands has a machine housing composed of insulating synthetic plastic shells, a fixed, web-shaped main handle formed as a part of the machine housing, an auxiliary handle, a drive including a motor and a transmission, at least one inner housing accommodating the motor and the transmission and surrounded by the synthetic plastic shells, and a tool driven by the drive. The handles, the machine housing, the inner housing and the tool are arranged so that forces applied to at least one of the handles are withdrawn from the machine housing by transferring the forces by the main handle directly to the inner housing without deforming the machine housing and then transferring the forces from the inner housing to the tool.

Abstract: A power-operated sword saw comprises a plate-shaped sword having a lower region with a guiding groove, two saw blades reciprocatingly movable in opposite directions parallel to one another and each having a front saw blade tip and an opposite clamping end. The saw blades have a toothed side provided with a plurality of teeth and an opposite saw blade back guided in the guiding groove of the sword. A drive is coupled with the clamping ends of the saw blades through a clamping unit. The saw blades are jointly coupled with the clamping unit and released from the clamping unit by a blocking element which blocks the clamping ends in a coupling position and release the clamping ends in a contact-free manner.

Abstract: An electric hand saw has a stationary sword having a lower side, a reciprocatable saw blade received in the lower side of the sword and having a rear end portion, a machine housing having a transmission outlet in which the rear end portion of the saw blade is received. The machine housing has a longitudinal slot located under the rear end portion of the saw blade. A suction passage is mounted on the lower side of the machine housing and has a sucking-in opening extending from the front end side of the suction passage to the longitudinal slot of the machine housing located under the rear end portion of the saw blade.
