The utility model discloses further set up to, locating hole one be the screw hole, the locating pin is inserted and is threaded connection with locating hole one.

Through adopting above-mentioned technical scheme, locating pin and the last locating hole fixed connection of nut avoid appearing the condition that the locating pin removed or dropped at will.

The utility model discloses further set up to, the direction of screwing of nut and set screw's the direction of screwing be clockwise and counter-clockwise respectively.

Through adopting above-mentioned technical scheme, the locking ability of the whole subassembly of reinforcing that can step forward appears becoming flexible to the nut, avoids driving set screw and appears becoming flexible, but, the not hard up direction of both is just opposite, so appear not hard up the degree of difficulty bigger.

The utility model discloses further set up to, locating hole one be equipped with two, two locating holes one at nut circumference direction evenly distributed.

The utility model discloses further set up to, locating hole two be equipped with a plurality ofly, a plurality of locating holes two are at set screw's circumference direction evenly distributed.

By adopting the technical scheme, the number of the second positioning holes is larger than that of the first positioning holes, so that the first positioning holes and the second positioning holes are aligned more easily.

The utility model discloses further set up to, still include annular anticollision cover, anticollision cover movable sleeve establishes on the bolt, is equipped with the through-hole that corresponds with locating hole one on the anticollision cover, and the locating pin passes from the through-hole.

Through adopting above-mentioned technical scheme, because the locating pin is long and thin structure, and expose outside, so when the locating pin receives the collision, can take place bending deformation, cause the damage, so set up the anticollision cover and protect the locating pin.

Adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

the utility model provides a bolt and nut fastening components, its set screw at end connection of bolt sets up the locating hole respectively on set screw and nut, and the locating pin is connected in the locating hole, so reaches locking purpose, and it is after the nut is screwed up, can adjust set screw's position according to the position of locating hole on the nut, makes the locating hole on nut and the set screw align, reinserts the locating pin.
