Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1-7, a novel electric wrench, includes controlling means 1, reduction gear 2 and sleeve 4, controlling means 1 includes battery 11, executes and twists switch 12, motor 13 and shaft coupling 14, battery 11 is located 1 inside edge of controlling means, it is located to execute and twist switch 12 the 1 outside of controlling means, motor 13 is located 1 inside center department of controlling means, the output shaft of motor 13 is installed in the shaft coupling 14, the output shaft of motor 13 and the input shaft of reduction gear 2, controlling

means

1 and 2's of reduction gear upper end fixed connection, the lower extreme of reduction gear 2 is located the sleeve top, reduction gear 2's output shaft with sleeve 4 links.

Further, the control device 1 is positioned at the uppermost layer of the whole wrench, and plays a role in controlling the operation of the whole device; preferably, the outer layer of the control device 1 is made of an insulating rubber material and a high-strength material, so that a cushioning effect is achieved.

Preferentially, the storage battery 11 adopts a high-capacity storage battery with strong storage capacity, and can be detachably replaced and charged; providing power for the operation of the entire device.

Still further, the screwing switch 12 is a self-resetting button. Controlling the opening and closing of the whole wrench; and pressing the button to start the operation of the wrench, loosening the button to stop the operation of the wrench, and controlling the opening and closing of the wrench in real time.

The motor 13 adopts a power-saving and efficient generator, and can drive the coupling 14 to effectively rotate; the coupling 14 is connected with the motor 13, and plays a role in driving the speed reducer 2 and the sleeve 3 to rotate.
