As the further improvement of the design, it is provided between the upper anti-sliding rib group and the lower anti-sliding rib group along the master
The waveform non-return rib of body circumferentially extending, further prevents main body from moving axially.
As the further improvement of the design, the cam in the lower anti-sliding rib group is all provided with jagged, is easy to the pressure of main body
Enter, annular plastics material is formed around lower anti-sliding rib group, is stablized.
As the further improvement of the design, fin presss from both sides with horizontal plane in the upper anti-sliding rib group and the lower anti-sliding rib group
Angle is 45 degree, prevents that main body axial movement effect is good.
The beneficial effects of the utility model are：The utility model by two groups of upper anti-sliding rib groups in opposite direction and under it is anti-skidding
Rib group active surface main body accepts rotation and prevents main body from moving axially, and effectively improves the stability of main body, improves service life,
Main body press-in working of plastics when the feeding cone is easy to assembling, upper anti-sliding rib group rotation direction with connection screw thread hole is oppositely oriented effectively prevents
Main body transfer when bolt screws out.
