Service life；If the radian of the first cambered surface is under 90 degree of cooperations more than the radian of 90 degree and the second cambered surface, it is subject in installation process
During to extruding, detent there will be metaboly and occurs, and detent intensity is poor, and service life can not be guaranteed；Such as
The radian of one cambered surface is under 90 degree of cooperations less than the radian of 90 degree and the second cambered surface, when being squeezed in installation process, positions
Groove there will be phenomenon of rupture and occurs, and detent intensity is poor, and service life can not be guaranteed；So the radian of the first cambered surface
More than 90 degree and the radian of the second cambered surface be 90 degree coordinate under relatively reasonable, detent bulk strength is stronger, it is ensured that use
Life-span.And on circular port, circumferentially it has been placed equidistant several around line groove, it is ensured that if being wound on of can firmly consolidating of coiling
Dry individual in line groove, thus be effectively guaranteed motor and can run normally；And the distance that two first between connecting portion by
One end becomes larger toward the other end, serves the effect of guiding, facilitates coiling, improve work efficiency in winding process；And
Angle formed by this first connecting portion and the second connecting portion is that angle formed by 128 degree and this second connecting portion and the 3rd connecting portion is
Under 125 degree coordinate, when extrude by coiling, there is an individual stronger reset force, further ensure that what coiling can firmly consolidate is wound on
Several are in line groove.
