Abstract: A multi-speed gear system for a power tool includes a case, a lever, a gear disk, a movable member, a ring gear, a planet gear unit and an idle gear unit. The movable member is axially moved to be engaged with the ring gear, the planet gear unit or the idle gear unit to change the gear ratios and output different speeds. The parts that are engaged with the movable member are located outside of the area where the gears are located, so that the switching between the speeds is smooth and has less friction.

Abstract: A clutch device for a power tool includes a case in which a washer, a clutch, a clutch ring, planet gears and a sun gear are installed. The washer is connected with pins to which springs are respectively mounted. When switching and setting the torque by rotating the torque member, the pins do not extend through the clutch. The output torque of the tool is smaller than the input torque of the main shaft, the clutch ring is rotated by the sun gear and the planet gears. The ratchet teeth of the clutch ring are disengaged from the clutch teeth of the clutch. When switching to the drill mode, the pins extend through the clutch and contact with the clutch ring, the motor activates the gear box. Because the clutch ring is fixed by the pins and cannot rotate, the gear box outputs the maximum torque to drill objects.

Abstract: A power output mechanism for power tools includes a main part for driving an output shaft, a switch unit, an impact unit, a pressing unit, and an operation member. The switch unit has a rotation collar for controlling positions of positioning springs. The impact unit includes an orientation wheel movably connected to the output shaft and an operation wheel secured to the output shaft. The orientation wheel includes a first toothed contact surface which is removably engaged with a second toothed contact surface of the operation wheel. A corrugated ring portion is defined on an outer periphery of the orientation wheel and limited from rotation relative to the output shaft when the positioning springs are moved to certain positions. When the positioning springs are engaged with the orientation wheel, the orientation wheel cannot freely rotate relative to the output shaft so that an impact is output.

Abstract: An output mode switching apparatus including a power unit, a hammering unit, an output shaft, a housing, and a shifting member is provided. The hammering unit includes a gasket cup, a switching ring, a spring member, a hammering seat, and a main shaft. When the power unit is not in operation, the switching ring is restricted so as to be positioned against and secured to the gasket cup. When the mains shaft is driven by the power unit to rotate, the hammering seat is carried to rotate and is applied with a restriction for restricting the hammering seat from axial movement, thus configuring an output mode of electric drill. When the shifting member is turned, the restriction applied to the hammering seat is released. The hammering blocks repetitively hammers the protrusion blocks and axially returns back to the original position, thus configuring an impact output mode.

Abstract: A main shaft locking mechanism includes a fixing ring, a main shaft and detents. The main shaft includes an equilateral portion that has an equilateral cross section. A number of the corners of the equilateral portion is equal to that of the detents. The detent has an exterior side and an interior side opposite to the exterior side. The interior side includes two corner protrusions protruded out from two ends thereof and a concave portion defined between the two corner protrusions. The corners of the main shaft are received in the concave portions of the detents. When the main shaft is manually driven to rotate, the corners of the main shaft drive the detents to deviate. Therefore, the exterior sides of the detents interfere against the fixing ring. Then the detents prevent the main shaft from further rotating, thus locking up the main shaft.

Abstract: A switching device for a power tool is provided. It comprises a housing, a rotary collar, an output axle with stepped portion, fixing gear wheel and a movable gear wheel. By the rotation of the rotary collar, the output axle can be retracted into the housing by an axial force to make contact of the movable gear wheel with the fixing gear wheel. Therefore, the switch collar device can adjust the output axle to switch between an position for simple rotation only and a position for rotation with impact. The whole structure of the present invention is more simple and cheaper than that of the conventional tool because it uses less parts.
