[0063] It should be noted that by providing a functional positioning column, the functional diversity of the electric bench vise of the present application can be improved when used.

When the motor is powered on, the motor drives the gear set to rotate, thereby driving the lead screw at the end to rotate, and the lead screw nut converts the rotational motion of the motor into the sliding linear motion of the jaws of the bench vise. When the jaws are clamped, the motor is blocked and the current passing through the motor increases sharply. The program determines whether the clamping action is completed by sensing the current size, thereby stopping the movement of the clamp after clamping the workpiece to prevent damage to the workpiece.
