ABSTRACT:
A mechanism for controlling circuit-closing/opening of power ratchet wrench, including: an elongated tubular main body for a user's hand to hold; a driving motor disposed in the main body; a transmission member disposed in the main body and connected with the driving motor for transmitting the power of the driving motor; a driving end disposed at the first end of the main body and drivable by the driving motor via the transmission member; a power supply for supplying power to the driving motor; a driving power supplying circuit disposed in the main body and electrically connected between the power supply and the driving motor, whereby the power supply can power on the driving motor via the driving power supplying circuit a controlling trigger, one end of the controlling trigger being pivotally connected with the main body. The controlling trigger is such arranged that when a user's hand encloses and holds the main body, the user's hand also encloses and holds the controlling trigger to control the closing/opening of the driving power supplying circuit.
