Abstract
A cosmetic applicator includes a head, a tube including a tube body, multiple driving teeth, a rotating sleeve disposed in the head, multiple driven teeth arranged alternately with the driving teeth, and a threaded rod threadedly connected to the rotating sleeve. Each driving tooth has driving and retarding surfaces. An angle formed between the driving surface and the tube body is smaller than that formed between the retarding surface and the tube body. Each driven tooth has driven and contact surfaces. An angle formed between the contact surface and the rotating sleeve is larger than that between the driven surface and the rotating sleeve and is different from that between the retarding surface and the tube body.
