[0002] A pointing device is a device that uses rolling to sharpen the end of a metal wire or rod, making it easier to insert into the die hole and then draw it to obtain a metal product of the desired length and shape. If there is no drawing device, it is usually called a heading machine.

[0003] The rolling device includes a frame, a motor, a reduction gearbox and a roller. The frame has an accommodating space, the motor is installed in the accommodating space, the top of the frame has a mounting surface, the reduction gearbox is installed on the mounting surface, and a roller frame is also installed on the mounting surface. The roller frame includes a first roller frame and a second roller frame which are arranged opposite to each other. The rollers are rotatably installed between the first roller frame and the second roller frame. The rollers include a first roller and a second roller which are arranged side by side up and down. The reduction gearbox includes a drive shaft. The drive shaft and the second roller are located at the same height. The drive shaft is connected to the second roller through a coupling.
