The gear transmission mechanism is connected between the motor and the output shaft to transmit the rotary power of the motor to the output shaft. The power tool comprises a signal generator and a control system electrically coupled to the signal generator and operatively engaged with the gear transmission mechanism such that when the signal generator is manually activated, an electric signal is generated and transmitted to the control system to cause the gear transmission mechanism to vary the gear reduction ratio. | 07-07-2011 |
| 20110154921 | RECIPROCATING CUTTING TOOL - A reciprocating cutting tool including a motor housing, a gear box connected with the motor housing, a motor disposed in the motor housing and a reciprocating mechanism disposed in the gear box. The reciprocating mechanism includes a suspending rack and a reciprocating shaft driven by the motor. The reciprocating shaft is connected to the motor by a reduction gear and an eccentric shaft. The suspending rack comprises a top plate and a bottom plate, the reciprocating shaft movably connected to the bottom plate, and would not reciprocate beyond the top plate in a reciprocating direction. Due to the reciprocating shaft not being guided and restricted by the top plate of the suspending rack, the reciprocating shaft would not extend beyond the top plate during the reciprocating motion, The present invention decreases the height of the gear box greatly relative to prior tools, and thus the height of the reciprocating cutting tool is likewise decreased, thereby increasing its application ability. | 06-30-2011 |
| 20100319947 | Electric Tool - The present invention relates to a power tool comprises an adjusting mechanism, the adjusting mechanism comprising a station element defining at least a first engaged member, and an adjusting member rotated about a axis and driving the first engaged member to move elastically along the axis, wherein a frequency increase mechanism is disposed between the adjusting member and the station element, the frequency increase mechanism coupled to the first engage member, the frequency of the elastic moving of the first engage member increases when the adjusting member rotates about the axis. Because the adjusting mechanism can increase the sound frequency, so it can make precision and dense sound and remind of the operator when the adjusting member rotated. | 12-23-2010 |
