Abstract
The invention discloses an electric wrench excellent in heat dissipation. The electric wrench comprises a wrench body. A supporting rod is arranged at the bottom of the inner wall of the wrench body. The bottom end of the supporting rod is fixedly connected with a positive-reverse motor. The surface of the positive-reverse motor is sleeved with a heat transfer cylinder. The surface of the heat transfer cylinder is fixedly connected with cooling fins. The surface of an output shaft of the positive-reverse motor is fixedly connected with a first fan and a second fan. The second fan is located on the left side of the first fan. The output shaft of the positive-reverse motor is fixedly connected with one end of a transmission shaft. The other end of the transmission shaft is fixedly connected with a sprocket. The surface of the sprocket is engaged with a clamping ring. The side face of the clamping ring is fixedly connected with a casing pipe. According to the electric wrench, by arranging the heat transfer cylinder and the cooling fins, heat is dissipated to the cooling fins quickly through heat conduction after the positive-reverse motor warms up; and by arranging protruding blocks, the heat dissipation area is enlarged, so that the heat dissipation speed of the electric wrench is higher, the first fan and the second fan rotate automatically to take away air in the wrench body, and accordingly the temperature of the electric wrench body is lowered.
