Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides an eccentric ball cage holder, includes holder body 1 and bell housing 8, its characterized in that: the retainer body 1 is annular, be equipped with positioning hole 2 on the lateral wall of retainer body 1, retainer body 1 is provided with main through-

hole

3, and 3 self-keepers's of main through-hole top run through the bottom to, the bottom outside of retainer body 1 is equipped with location ball 5, retainer body 1's top and bottom all are equipped with two fixed slots 4, and the fixed slot 4 at top and the fixed slot 4 position one-to-one of bottom, a plurality of ball grooves 10 have been seted up to the inner wall of bell-shaped shell 8, ball groove 10 position is right with positioning hole 2 one earlier on, and has seted up spacing groove 9 between two sets of ball grooves 10 at interval.

The number of the positioning through holes 2 is six, and the positioning through holes are uniformly distributed on the side wall of the retainer body 1 at the same interval by taking the center of the retainer body 1 as a circle center; the lower end of the retainer body 1 is provided with accommodating grooves 7, the accommodating grooves 7 are positioned between two spaced groups of positioning through holes 2, the number of the accommodating grooves 7 is six, the outer openings of the accommodating grooves 7 are smaller, the inner openings of the accommodating grooves 7 are larger, the bottoms of the accommodating grooves 7 are fixedly connected with springs 6, positioning balls 5 are arranged above the springs 6, the number of the positioning balls 5 is the same as that of the accommodating grooves 7, multi-angle fixation is guaranteed, and slipping is avoided; the positioning ball 5, the retainer body 1 and the bell-shaped shell 8 are all made of high-strength alloy, so that the strength of the device is ensured; limiting grooves 9 are formed between the ball grooves 10 and the ball grooves 10 of the outer shell 8, the number of the limiting grooves 9 is six, the limiting grooves 9 are aligned with the positioning balls 5 one by one, and the depth of each limiting groove 9 is smaller than the depth of the inner portion of the outer shell 8.
