One end of the power supply fixing device is movably assembled at a plate in the computer case, and a suppress surface is used to suppress the power supply. In addition, by hooking at the other end, which is formed at the fixing device, to the other plane of the computer case, and by moving an operating member of the fixing device to a packing position, the entire power supply can be fixed. The entire operation process is performed without an aid of a hand tool, and there is no need to use screws or screw holes, such that the power supply can be dismantled and assembled more conveniently. | 12-02-2010 |
| 20110064536 | Electronic component fixing device - An electronic component fixing device, which includes the restraining piece positioned in a horizontal direction to an electronic component, and at least one antiskid screw positioned in a vertical direction to the electronic component. When installing the electronic component, the restraining piece is assembled to a retaining wall of a computer case, and the antiskid screws are caused to movable penetrate a partition of the computer case, thereby separately restraining the horizontal surface and the perpendicular surface of the electronic component so as to suppress vibration in a horizontal direction and vertical direction of the electronic component when operating, and reduce noise produced by friction or impact with the computer case. | 03-17-2011 |
| 20110090642 | Heat Dissipation Device - A heat dissipation device which is assembled in a computer case is primarily constituted by a cooling fan, a circuit drive unit, an MCU (Microcontroller Unit) chip and a light emitting unit. The MCU chip is used to detect a power load of a power supply, and the circuit drive unit is used to drive the light emitting unit to produce a change of various light colors, according to a result of detection; this allows a user to identify a power load and output of the power supply by watching directly. | 04-21-2011 |

| 20090151966 | Switching Device For Impact Power Tool - A switching device for an impact power tool includes an input unit, a clutch unit, an output unit and a spring. The clutch unit is cooperated with the spring and located between the input unit and the output unit. The clutch unit includes a clutch disc connected to an input shaft of the input unit and a collar. The output unit includes an output shaft with struck blocks and a pounding member with striking blocks. When the collar is moved and connected with the clutch disc, the input shaft, the pounding member, the collar and the output shaft rotate simultaneously. The output shaft outputs rotation only. When the collar is moved and disengaged from the clutch disc, the input shaft drives the pounding member and the pounding member drives the output shaft to rotate. The output shaft outputs rotation with impact intermittently. | 06-18-2009 |
| 20090169336 | Locking Device With Quick Release Mechanism - A locking device includes an outer ring in which a clutch disc and a locking disc are respectively connected at two opposite sides thereof A first pad is located on clutch disc and a second pad is located on the first pad. A plurality of balls are located between adjacent first and second protrusions of the first and second pads. A plurality of springs are biased between the far first and second protrusions. A screw bolt connected with a grinding wheel is threadedly extended through the locking disc. When the outer ring is rotated in first direction, the balls do not fall into the recesses defined in the locking disc so as to push the clutch disc to lock the grinding wheel. When the outer ring is rotated in second direction, the balls fall into the recesses and the clutch disc is loosened from the grinding wheel. | 07-02-2009 |
| 20090277291 | Power Output Mechanism For Power Tools - 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. | 11-12-2009 |
| 20100319945 | OUTPUT MODE SWITCHING APPARATUS - 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. | 12-23-2010 |
| 20110030984 | MAIN SHAFT LOCKING MECHANISM - 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. | 02-10-2011 |
| 20110053728 | MULTI-GEAR MECHANISM FOR POWER TOOLS - A multi-gear mechanism includes first and second gear sets, an output set, multiple first planet gears pivotably connected between the first and second gear sets, a first gear ring having internal teeth and external teeth, multiple second planet gears cooperated with the internal teeth of the first gear ring, a second gear ring having internal teeth and side teeth, an operation gear ring and a motor gear. The motor gear extends through two central holes of the first and second gear sets, and the first and second planet gears are engaged with the motor gear. The operation gear ring is connected with the second gear ring which drives the operation gear ring to move axially. The motor gear drives the output set at low speed, constant speed or high speed when the operation gear ring and the second gear ring are operated to engage with different gears. | 03-03-2011 |
