The invention discloses an electric bench screw. The electric bench screw does not need to be pulled manually, works electrically, is controlled through a circuit and is operated through buttons, application is convenient and rapid, and the working efficiency is high. According to the technical scheme, firstly, a storage battery is used as a power source, and power is provided by a direct-current motor; secondly, an electromagnetic clutch device is arranged and used for transmitting the power of the direct-current motor to a screw for rotation; thirdly, a high-gear reducing transmission device and a low-gear reducing transmission device are arranged, and speed adjustment is facilitated; and fourthly, a control panel and the control circuit are arranged and used for controlling the direct-current motor and the electromagnetic clutch device. The electric bench screw has the beneficial effects that the workpiece clamping speed is high, the efficiency is high, manpower is saved, work fatigue of operators is relieved, and the working efficiency and production benefits of bench worker of all walks of life can be improved.
