An outer end of the workbench 9 is fixedly connected to a motor 13, and an output end of the motor 13 passes through the workbench 9 and is provided with a lead screw 22 inwardly. Two movable frames 24 are threadedly connected to the lead screw 22, and the internal thread directions of the two movable frames 24 are completely opposite. By starting the motor 13, the lead screw 22 can be driven to rotate. Since the thread directions of the two movable frames 24 are opposite, their relative movement can be achieved, and the spacing between the thread rolling rollers 5 can be adjusted, which is suitable for thread rolling operations of screws of different sizes.
