AI Technical Summary
Traditional quick-change tool heads for electric drills suffer from problems such as high noise, severe wear, heavy weight, difficult processing, and uneven springback, failing to meet market demands for lightweight and noise reduction.
It adopts a combination structure of plastic sleeve and metal inlay. The plastic sleeve is made of nylon, and the metal inlay is connected by injection molding. The sliding contact part is located on the plastic sleeve or metal inlay, which reduces friction and noise, enhances connection strength, and reduces weight.
This invention achieves a quick-change tool head connection structure for electric drills that features low noise, good locking effect, light weight, high yield, long life, and smooth rebound, meeting market demands.
