Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in further detail by embodiment:
Embodiment as elastic force aligner described in the utility model, such as Fig. 1, shown in Fig. 2 and Fig. 3, lower end is located in glass groove 1, including reaction bowl cover 2, sleeve 3, bearing pin 4, spring 5 and base 6, described sleeve 3 is provided with installing hole 7 and lower installing hole 8 in the axial direction, the lower end of described reaction bowl cover 2 is inserted in described upper installing hole 7, the upper end of described bearing pin 4 is inserted in described lower installing hole 8, lower end passes described base 6, and expose outside the lower surface of base 6, described spring 5 is sleeved on described bearing pin 4, the upper end of described spring 5 is connected with described bearing pin 4, lower end is connected with described base 6, described reaction bowl cover 2 is provided with the metal needle 9 being connected with detection device for elasticity (not shown).Described bearing pin 4 is provided with pin 10 diametrically, described pin 10 is provided with fixing hole 11 diametrically, the upper end of described spring 5 is inserted in fixed hole 11, described base 6 upper surface is provided with projection 12, described projection 12 is provided with lower fixed hole 13, and the lower end of described spring 5 is inserted in described lower fixed hole 13.The lateral surface of described base 6 is provided with a circle groove 14, is provided with sealing ring 15 in described groove 14, mutually conflicts in the medial wall of described sealing ring 15 and described cup groove 1.Described sleeve 3, reaction bowl cover 2, bearing pin 4 link together with the upper end of spring 5 after linking into an integrated entity, it is can be in relative rotation between lower end and the base 6 of described bearing pin 4, described base 6 and sealing ring 15 are owing to can rotate relative to bearing pin 4 under the drive of the rotatory force acting on glass groove 1 of frictional force, now, spring 5 can bear certain twisting force.
