[0002] With the improvement of living standards, people's personalized needs for their appearance have increased, and their requirements for personal image have gradually increased. Therefore, barber scissors are a commonly used personal care product and consumables, and their annual demand is huge.

[0003] The blade of a trimmer is usually composed of multiple parts. Since the trimmer is small in size and has many parts, the trimmers that are assembled in small batches are usually assembled manually with jigs. This method usually requires the use of more transfer pallets to transfer the products between various process stations, and each station requires independent feeding and unloading methods. The time cost and manpower turnover cost are wasted, and it can only meet smaller production needs.
