Described contact supports 4 to install dynamic iron core 43 by steady pin 42, is specially and arranges pin-and-hole in contact support 4, is provided with pin-and-hole accordingly at dynamic iron core 43, then, is sequentially inserted in two pin-and-holes by steady pin 42, dynamic iron core 43 is arranged on contact and supports on 4.
Described bolster 41 is radially extended the capping 412 formed formed by buffering main body 411 and buffering main body 411.Buffering main body 411 is arranged on contact and supports that, on 4 impingement areas contacted with the body 3, elastic buffer face is formed in buffering main body 411, and covers 412 and be resisted against steady pin 42 end, thus limits steady pin 42 and deviate from, and its structure is relatively simple, saves use cost.In the present embodiment, in described capping 412 formed containing cavity, steady pin 42 end be placed in containing cavity with capping 412 against.
Such as Figure 18 b and Figure 18 c, and shown in Figure 18 d and 18e, described capping 412 is point cantact or linear contact lay with contacting of the body 3.Described capping 412 contacts one end with the body 3 and could be arranged to sphere, is point cantact with the body 3, it is also possible to be set to cylinder, it is linear contact lay with the body 3, make contact support 4 rub less with the body 3, and then make contact support 4 and the body 3 wear and tear less, save use cost.
In the present embodiment, when bolster 41 is installed, buffering main body 411 mounting groove 44 is set in described contact support 4, mounting groove 44 at least one end forms block 441, buffering main body 411 at least one end forms the breach 4111 mated with block 441, buffering main body 411 is arranged in mounting groove 44, and block 441 is stuck in breach 4111 restriction bolster 41 horizontal direction and departs from.
Arranging the first grab 413 in buffering main body 411, and arrange the first draw-in groove 442 in contact support 4, bolster 41 is supported on 4 with the installation contact that coordinates of the first draw-in groove 442 by the first grab 413.
Arranging the second draw-in groove 45 in described contact support 4, capping 412 arranges the second grab 4121, bolster 41 is arranged on contact and supports on 4, and the second grab 4121 snaps in and limits the disengaging of bolster 41 vertical direction in the second draw-in groove 45.
For further enhancing the elastic buffer effect of bolster 41, 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, i.e. it is set to relatively thin away from covering 412 positions, and it is set to thicker near capping 412 positions, make it elastic preferably, and intensity is enough.
As shown in Figure 19 to Figure 21, the boss 12 installing reaction spring 11 it is provided with on described base 1, described boss 12 periphery is provided with the diastrophic circle barricade 13 of restriction reaction spring 11, make the reaction spring 11 will not flexural deformation when forced compression, thus it being not result in that reaction spring 11 force value changes, properties of product are relatively stable.Axial ribs, reaction spring 11 and axial ribs point cantact are set on barricade 13 medial wall so that the friction between reaction spring 11 and axial ribs is less, and reaction spring 11 scales the most 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, described contact supports that the bottom of 4 and the distance on barricade 13 top are more than reaction spring 11 coaxial maximum compression stroke so that movement parts contact supports that 4 motions are the most smooth and easy.
On described barricade 13 top inner side wall, a circle is set and prevents the rounded corner 131 of reaction spring 11 clamping stagnation so that reaction spring 11 will not clamping stagnation on barricade 13, it is ensured that reaction spring 11 compresses smooth and easy.
Described boss 12 is set to two of symmetry, and each boss 12 periphery is provided with the diastrophic circle barricade 13 of restriction reaction spring 11 so that reaction spring 11 active force that contact support 4 is subject to more balances, and moves relatively stable.
The foregoing is only the preferred embodiments of the present invention, not the restriction to this case design, all equivalent variations done according to the design key of this case, each fall within the protection domain of this case.
