The electric motor (20) is connected to the gearbox (10). A portion of the lead screw (30) is received inside the gearbox (10) and driven by the electric motor (20), and another portion of the lead screw (30) is extended out of the gearbox (10). The extension pipe (40) is movably fastened to the lead screw (30). The load bearing structure (50) includes a sleeve (51), a bearing (52), a fastening element (53), a fixation seat (54) and a rear supporting seat (55). The sleeve (51) is mounted to the lead screw (30) and holds the bearing (52) jointly with the fastening element (53). The fixation seat (54) and the rear supporting seat (55) hold the bearing (52) at outer perimeters of the sleeve (51) and the fastening element (53).

A hand tool with a mechanical linear drive mechanism coupled to a linear activated working implement. The drive mechanism includes a roller screw that includes a torque tube connected to a roller screw's nut body. The roller screw includes a fixed outer race, a rotating set of grooved rollers axially aligned inside the outer race, a cylindrical nut body located inside the set of grooved roller, a plurality of inner rollers axially aligned and inside the nut body, a threaded shaft axially aligned and inside the inner rollers, and a torque tube axially aligned inside the inner rollers. The torque tube is connected at one end to a multiple speed gear box which includes a primary motor coupled to a earner gear with three planet gears. Disposed around the planet gears is a ring gear. Coupled to the ring gear is a secondary motor which when activated causes the ring gear to rotate in the opposite direction of the planet gears. At least one sensor measures the rotation of an elastomeric ring and control activation of the secondary motor to change the operational speed of the tool.

A drive device for a movable furniture part, comprising an ejection force accumulator which can be tensioned, an ejection element mechanically loaded by the ejection force accumulator and used to carry out an ejection movement of the moveable furniture part from a closed position into an open position. The ejection movement can be initiated by a compression movement of the movable furniture part into a compression position which is behind the closed position. The drive device also comprises a tensioning device for tensioning the ejection force accumulator with energy which can be emitted by the ejection movement. During the compression movement, at least 50% of the energy emitted by the ejection force accumulator during the ejection movement can be introduced into the ejection force accumulator by the tensioning device.

An actuator assembly having an actuator, a worm gear, a first gear unit, a second gear unit, and a biasing member. The actuator may rotate the worm gear, first gear unit, and second gear unit in first rotational directions while the biasing member may rotate the worm gear, first gear unit, and second gear unit in second rotational directions.

A transmission device for a power-driven cutting tool includes a base, a transmission component, a linking component, a shaft component and a link component. The base has a through cavity, a sleeve and a receiving portion. The transmission component is penetratingly disposed in the through cavity, so as to couple the transmission component and the base together. The linking component is penetratingly disposed in the sleeve, so as to couple the linking component and the base together. The shaft component and the link component are disposed in the base. A power source drives the linking component and thereby sequentially drives the shaft component, link component, and transmission component, allowing a cutter of the power-driven cutting tool to undergo reciprocating displacements along a linear path for performing a cutting operation. The transmission device features enhanced structural rigidity, allowing the cutter to move back and forth along a linear track.

In one aspect, the present disclosure provides a parking brake device for a motor vehicle. The device may include a vehicle transmission including a parking lock and a gear selector lever coupled with the parking lock, where the gear selector lever is movable into a parking lock position for engaging the parking lock, and where the gear selector lever is movable out of the parking lock position for disengaging the parking lock. A first mechanical transmission element and a second mechanical transmission element may be arranged between the gear selector lever and the parking lock, where the first mechanical transmission element may be connected with the gear selector lever and configured for transmitting a moving force emanating from the gear selector lever to the second mechanical transmission element, and where the second mechanical transmission element may be connected with the parking lock.

An operator assembly may move a window vent relative to a frame. The operator assembly includes a stationary member, an arm and a drive member. The arm is mounted for rotation relative to the stationary member between an open position and a closed position. The drive member is received in a channel defined by the stationary member for linear motion therein relative to the stationary member and the arm among a first position in which the drive member engages a locking feature of the window vent, a second position in which the drive member is spaced apart from and disengaged from the locking feature without rotating the arm out of the closed position, and a third position in which the drive member is further spaced apart from the locking feature. Movement of the drive member between the second and third positions moves the arm between the closed and open positions.
