Fig. 2 is the structural representation of the rolling body of rolling supporting mechanism.

Embodiment

Referring to Fig. 1, Fig. 2, the use servicing unit of large calibre threads ring gauge of the present utility model, it comprises, hanging beam 1, its central authorities have a guide hole 11; Two

guide poles

2,3 are individually fixed in hanging beam 1 two ends, and back-up

ring

21,31 is established in its lower end, as the lower limit of guide pole; Two guide holders 4,5 are movably set in

guide pole

2,3 respectively, move up and down along

guide pole

2,3; Wheel carrier 6, it is a ring texture, and its both sides are connected and fixed on two guide holders 4,5 respectively, set up three fixedly projections 61,62,63 separately along inwall, and this fixedly has fixed groove 611 on the projection 61,62,63;

Referring to Fig. 2, rolling supporting mechanism 7 comprises three pairs of

rolling bodys

71,72,73, and this rolling body 71 comprises two rollers 711,712, roller shaft 713,714, bearing 715; Two rollers 711,712 are relatively arranged on wheel carrier fixedly in the fixed groove 611 of projection 61 by roller shaft 713,714, and are fixing by pin 716; Bearing 714 is arranged between roller 711 and the roller shaft 713, and described roller 711,712 outer faces extend to form a
