Problems solved by technology
[0009] The problem to be solved by the electric quick-turn wrench and its use method of the present invention is that it will take a lot of time for the user to pull the nut back and forth with the existing manual wrench, and the screw rod often has the problem of rust in some construction environments If it happens, the user must pull the wrench hard to make the nut pass through the position where the screw rod produces resistance due to rust, resulting in time-consuming and labor-intensive shortcomings. However, the existing electric wrench cannot be driven smoothly when it encounters a construction environment with a torque greater than that provided by the motor. The rotation of the transmission part and the driving part is more likely to damage the internal structure of the electric wrench

The invention provides an electric rapid rotating spanner and a use method thereof. The electric rapid rotating spanner comprises a body, a drive device, a power device, a transmission device and a clutch device; the drive device is arranged on the body and can drive a fixing part; the power device is arranged on the body so as to provide torsion; the transmission device is arranged between the drive device and the power device and is arranged on the body rotationally along a rotary shaft; the transmission device is suitable for transmitting torsion provided by the power device so as to drivethe drive device; the clutch device is arranged between the drive device and the power device and comprises two on-off parts which are connected mutually in a separable mode in the radius direction ofthe rotary shaft; and when the resistance of a position is larger than the torsion provided by the power device or a preset torsion value in the process that the electric rapid rotating spanner drives the fixing part, the two on-off parts are repeatedly connected and separated, at the moment, the body can be pulled manually, and the fixing part is forced to pass through the position.
Description
technical field [0001] The invention mainly relates to an electric wrench, especially an electric fast-turn wrench with a fast-turn function. Background technique [0002] Please refer to the U.S. Patent No. 8800410 patent case "Ratchet wrench with directionswitching structure", which discloses a reversing ratchet wrench, which includes a wrench body (wrench body), a ratchet wheel (ratchet wheel), a drive member (ratcheting member) and a control member (switching member), the ratchet ring is rotatably arranged on the wrench body and can be connected to the sleeve, the drive member is arranged on the wrench body and selectively uses the left half portion or the right half portion portion) snaps the ratchet ring, so that the rotation direction of the ratchet ring is converted, and the control part is pivotally arranged on the wrench body and abuts against the driving part. [0003] The user must hold the wrench body and swing back and forth left and right to make the ratchet ...
