Abstract

The utility model discloses a novel oil-free cartridge which comprises an outer shell, screws, forks and beads. The outer shell is located on the outer side of the screws and is axially fixed with the screws. The forks are located in the screws. The screws are provided with guide grooves. The beads extend into inner cavities of the forks from bottoms and are fixed. Four protrusions are arranged on the outer side of each bead. The forks are provided with through holes. The protrusions of the beads penetrate through the through grooves in the forks and then fall into the guide grooves of the screws. The forks are arranged on the two ends of a through groove. The two sides of each fork are respectively provided with two salient points. A base of each fork is formed by combining an inner side groove and an outer side protruding rib. The forks are made of PP materials. The screwed groove depth of the screws is larger than a changed screw depth. By the adoption of the mode, the novel oil-free cartridge can solve the problems that oil goes out of a conventional cartridge and cause the surface of a product to be polluted by the oil, or rustle sound is caused by rotation lacking oil. The novel oil-free cartridge reduces manpower and material resources and protects the environment.
