In described body both ends of the surface, be provided with catch, two described catch cover the both sides of roller, spring, spring compressor and spring seat.
Adopt said structure, can prevent that the parts such as roller, spring, spring compressor and spring seat from skidding off from roller slot two ends.
In the form of a ring, this catch is connected on body by rivet described catch, and described spring seat clamping is between two described catch, and this spring seat and body outer peripheral surface are close to.
Catch is worn and is arranged on body by rivet, its outer side surface is concordant with body end face, spring seat clamping is between two catch, spring seat can be made by nylon, by screw or rivet, be fixed on catch, be convenient to install, during installation, first two catch be arranged on body end face, then spring seat is arranged between two catch.
The anterior wide rear portion of described spring seat is narrow, and this spring seat front end is uncovered, and the uncovered portion of this spring seat is stuck on described roller outer wall, and described spring seat rear portion snaps in described spring front portion.
The spring seat of said structure, its anterior open-mouth is stuck on roller outer wall, with between roller, form contacting of many places, a roller part is positioned at that it is uncovered, make between roller and spring seat butt more firm, spring seat rear portion is stretched in spring front portion, and spring at front end is connected on spring seat outer wall, stable connection between spring seat rear portion and spring, spring seat adopt above-mentioned structure make between spring, spring seat and roller butt or annexation more firm.
Described spring seat is U-shaped or V-type, and the front end of this spring seat is outwards turnover respectively, and the width of this spring seat front end is greater than width or the diameter of described spring at front end.
The spring seat of said structure, simple in structure, be convenient to produce, its front end inner side is stuck on roller outer wall, and in conjunction with firm, the width of spring seat front end is greater than width or the diameter of spring at front end, guarantee that spring seat can all not slip in spring, butt is effective, has strengthened the durability of spring compressor and spring.
On described body inner peripheral surface, offer keyway.Be convenient to be connected with rotating shaft.
Described roller slot and roller are 6-12.
A plurality of roller slots and roller are set, make the carrying torsion of free wheel device larger, roller slot also can be set to 8,9 etc.
The beneficial effects of the utility model are: roller slot is arranged on body outer peripheral surface, are convenient to processing and the assembling of clutch, enhance productivity, and make the more firm of butt between spring, spring seat and roller, guarantee the reliability of clutch work.
