The beneficial effects of the utility model are：This utility model can be utilized when specifically used, first and commonly beaten
Hole instrument gets out a fixing hole in fixed station, and the debris then cleared up in the fixing hole afterwards integrally insert this utility model
Enter in the fixing hole, and rotate the nut using torque wrench class instrument and make the nut push the expansion sleeve and make the expansion sleeve
Cylinder bottom runs into and expand and be inserted in the hole wall of the fixing hole to surrounding after the jacking block, so as to this utility model is firmly solid
In being scheduled on the fixing hole, will finally need to be arranged on the bolt body of rod top by fixed object, the elastic packing is arranged successively
Circle body, the rigid washer and the nut to complete overall installation fixation work, while by the bullet of the elastic packing circle body
Property the effect of pad pressure can make overall fixed effect more preferably, while the elastic seal ring body is prevented from the bolt body of rod sliding
And can improve payload of the present utility model.
