description The utility model provides the technical scheme of a mechanical reversing electric wrench. The mechanical reversing electric wrench comprises a power mechanism, a planetary transmission device, a counter-force output mechanism, a sleeve (2), a first grade central wheel (5) and a transition wheel (20). The mechanical reversing electric wrench is characterized by further comprising a mechanical reversing device; and the mechanical reversing device comprises a reversing transmission mechanism and a manual reversing mechanism. In the scheme, because the rotating direction of the wrench is not controlled by changing the running direction of a motor by a switch, the phenomena that the motor is burned out and personal injury phenomenon caused by sudden reversing of the motor because of the misuse and mistakenly pressing the switch in the construction can be avoided. The wrench is simply and exactly controlled by knobs without error operation factors; the personal injury and machine damage caused by error operations
