Embodiment
As shown in Figs 1-4, this high safety brake spring, including by the spiral body 2 of 1 coiling of metal thin bar, sheet
2 one end of body is equipped with three the first positioning convex bodies 3 being distributed along 1 arc-shaped shape of metal thin bar, the first positioning convex body 3 and metal thin bar
1 is integrally formed, and 3 outer end of the first positioning convex body is equipped with spacing blind hole 31, on 3 outer end of the first positioning convex body is further opened with that limit can be made
What position 31 radial direction of blind hole connect with outside first leads mouth 32, first lead the middle part of mouth 32 be at closing waist shape and closing waist minimum widith is less than
The diameter of spacing blind hole 31, three first central axes for leading mouth 32 are parallel to each other, and 2 other end of body is equipped with three along metal thin bar
Second positioning convex body 4 of 1 arc-shaped shape distribution, the second positioning convex body 4 and metal thin bar 1 are integrally formed, outside the second positioning convex body 4
End is equipped with the second spacing blind hole 41, be further opened with making on 4 outer end of the second positioning convex body the second spacing 41 radial direction of blind hole with it is outer
The second of portion's connection leads mouth 42, and second leads the middle part of mouth 42 is less than the second spacing blind hole 41 in minimum widith at closing waist shape and closing waist
