Described spring seat is U-shaped or V-arrangement, 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, to 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, guarantees that spring seat can all not slip in spring, and butt is effective
On described body, offer at least three attachment holes, the center of this attachment hole be evenly distributed on described body concentric same circumference on, the diameter of this circumference
value be 72mm-76mm.
Attachment hole is connected for body and miscellaneous part, and the restriction of the diameter of circumference meets its installation position in practical, prevents the too close roller cell wall of attachment hole, affects the intensity of clutch, the diameter of circumference
can be 73mm, 74mm, 75mm etc.
On described side wall of outer shell, offer the corresponding tank filler sleeve with described roller slot.
On shell corresponding to body side, offer tank filler sleeve, this tank filler sleeve and roller slot partly overlap, and can allow roller sub-fraction come out, oily to roller by tank filler sleeve, can also reduce the material of shell simultaneously, cost-saving.
Described body offers positioning hole on right side, offers the through hole corresponding with this positioning hole on described shell, and the edge of this through hole extends in positioning hole, and snaps onto on positioning hole hole wall.
Said structure makes between shell and body, in conjunction with tightr, can to reduce the material of shell simultaneously, cost-saving
On the left side of described body, baffle plate is installed.By baffle plate, block the parts in ball grooves.
Described catch and shell are one-body molded.Shell and catch are connected firmly, are convenient to install simultaneously.
The beneficial effects of the utility model are: be convenient to clutch and connection miscellaneous part, make spring position limited better, make the more firm of butt between spring, spring seat and roller, guarantee the reliability of clutch work, and be convenient to roller oily.
