For strengthening the elastic buffer effect of bolster 41 further, described elastic buffer face is the elastic buffer face of concavo-convex setting, and buffering main body 411 two ends are set to thinner thickness, namely be set to thinner away from capping 412 position, and be set to thicker near capping 412 position, make its elasticity better, and intensity is enough.
As shown in Figure 19 to Figure 21, described base 1 is provided with the boss 12 installing reaction spring 11, described boss 12 periphery is provided with the diastrophic circle barricade 13 of restriction reaction spring 11, make reaction spring 11 can not flexural deformation when forced compression, thus reaction spring 11 force value can not be caused to change, properties of product are comparatively stable.Barricade 13 madial wall arranges axial ribs, and reaction spring 11 and axial ribs point cantact, make the friction between reaction spring 11 and axial ribs less, reaction spring 11 convergent-divergent is comparatively smooth and easy.
In the present embodiment, described reaction spring 11 is placed in barricade 13, one end is arranged on boss 12, the other end is arranged on contact and supports on 4, the bottom of described contact support 4 and the distance on barricade 13 top are greater than the coaxial maximum compression stroke of reaction spring 11, and movement parts contact is supported, and 4 motions are comparatively smooth and easy.
Described barricade 13 top inner side wall arranges the rounded corner 131 that a circle prevents reaction spring 11 clamping stagnation, make reaction spring 11 can not clamping stagnation on barricade 13, ensure reaction spring 11 compress smooth and easy.
Described boss 12 is set to symmetrical two, and each boss 12 periphery is provided with the diastrophic circle barricade 13 of restriction reaction spring 11, and reaction spring 11 active force that contact support 4 is subject to comparatively balances, and moves comparatively stable.
The foregoing is only preferred embodiment of the present utility model, not to the restriction of this case design, all equivalent variations done according to the design key of this case, all fall into the protection range of this case.
