【Specific embodiment】
Refering to Fig. 1 and 2, a kind of bolt group not easy to remove of the utility model, including screw rod 1, turn 2, first sleeve
5th, spacing 3, abnormity nut 4, second sleeve 6, the one end of the screw rod 1 is fixed with and turns 2, and the other end of screw rod 1 is by connection
Rod 13 is connected with spacing 3, described to turn 2 in cylinder, and the side wall for turning 2 is provided with some pin holes 20, described to twist
Dynamic 2 outsides are cased with first set cylinder 5, offer on the first sleeve 5 and turn 2 first through hole 52 being engaged, the first sleeve 5
In outer-hexagonal shape, the side wall of first sleeve 5 is provided with some jacks 50 coordinated with pin hole 20, inserts on each jack 50
There is the hold-down bars 51 of an insertion correspondence pin hole 20, described spacing 3 hemispherical, and the planar ends of spacing 3 are near screw rod
1, the abnormity nut 4 is in outer ellipse, and second sleeve 6 is cased with outside abnormity nut 4, is offered in second sleeve 6 and abnormity
The second through hole 64 that nut 4 is engaged, second sleeve 6 is in outer-hexagonal shape, and the one end of the abnormity nut 4 closing, nut is provided with
Screwed hole 40, the bottom of screwed hole 40 is provided with a draw-in groove 41, and the bottom of draw-in groove 41 is hemispherical, the side wall of draw-in groove 41 be provided with it is some only
Can be described to turn 2 and be furnished with a block 22 to the baffle plate 42 of the bottom direction of draw-in groove 41 upset, turn 2 not with the first sleeve 5
With hold-down bars 51 with the use of when block 22 cover turning on 2, turning has paste lubricating oil between 2 and the gap of block 22
Layer 23,2 bottom margin that turn are provided with a circle flange 21, and the external diameter of flange 21 is more than the external diameter of block 22, the jack
