Abstract: 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.

Abstract: A shockproof spindle includes a spindle inserted into an elastomer having a compressible structure, and a sleeve having a hollow cylinder, sequentially. The sleeve caps the elastomer while the elastomer is pressed on the top of the base fixed at the bottom end the spindle to expose the chute of the spindle. The ball is then disposed in the chute of the spindle and the chute of the sleeve. After the sleeve is released to return the elastomer to its normal state, the sleeve, the elastomer and the spindle are held together by the ball which is retained in the chutes of the spindle and the sleeve. A C-shaped plate is then inserted between the elastomer and the base.

Abstract: An automatic speed shifting device includes a frame having a transmission device and a torque feedback device received therein. The torque feedback device has a torque resistant member so that when the load torque is smaller than its resistant torque, the speed reduction mechanism of the transmission device is remained at the first stage speed status. When the load torque is larger than its resistant torque, a pushing wheel devices a clamp to compress a shifting gear so that the speed reduction mechanism is shifted to another stage of speed. The speed reduction mechanism of the transmission device automatically shifts the speed reduction mechanism when the load torque increases or reduces such that the mechanical efficiency of the transmission device can be increased.

Abstract: Electric tool knob control apparatus comprises a compressing spring and a cam controller, which are set consequently on the sleeve of drive shaft base. Compressing spring is set between cam controller and base. On the sleeve, an external gearwheel is installed. Cam controller includes a spur cam-disk and a passive cam-disk. On spur cam-disk and passive cam-disk, a cam-disk flange and a cam-disk recess are circularly arranged and oppositely set up; therefore, cam-disk flange and cam-disk recess may engage to each other. On spur cam-disk, a plurality of planet gearwheel is set pivotally. By covering the outside of cam controller and sleeve with a knob with inward gear set inside diameter, planet gear wheel may engage with inward gear and external gear wheel in the same time. Also, passive cam-disk, which engages with knob, may rotate with knob and move in axial direction of knob. Passive cam-disk and spur cam-disk may be driven to rotate while knob is moved to rotate. Therefore, passive cam-disk moves along axial direction to relax and compress the compressing spring for regulating drive shaft torque. By the rotational speed difference, knob may regulate torque and be homed in 360°.

Abstract: A power tool includes a variable speed device which can be set in an auto mode or a manual mode. The power tool does not need the user to set the speed when it is operated at the auto mode. The power tool is reset to be the high-speed mode when it is activated. The speed is reduced along with the working load so as to output high torque, maintain the best working efficiency and protect the power tool under the operative status. The power tool can be set to the manual mode so as to work in a single type of function.

Abstract: An output mode switching device includes an output unit, a stationary ratchet gear unit, a spring, at least one block, a case for accommodating the parts mentioned above, and a control device threadedly connected to the case. The output unit includes an output shaft and a first bearing and a movable ratchet gear connected thereto.

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.
