[0024] It is worth mentioning that the guide rail slider 202 moves in the direction of the fixed seat 308, and the movement of the guide rail slider 202 drives the clamping frame 205 to move in the direction of the fixed seat 308. After the lower surface of the clamping frame 205 slides to a suitable position on the upper surface of the fixed seat 308, the first electric telescopic rod 212 is started to clamp one end of the wire harness, and then the control panel 201 is used to make the guide rail slider 202 slide in the opposite direction to facilitate the adjustment of the length of the wire harness as needed, and the cutting mechanism 3 is used for clamping, and then the motor 203 is started to facilitate the winding of the two wire harnesses together.
