Drawings

The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and together with the description, serve to explain the principles of the disclosure.

Fig. 1 is a schematic view of the overall structure provided by the present invention.

Fig. 2 is a schematic view of the bolt structure provided by the present invention.

In the figure: 1. the nut column comprises a nut column body, 2. a bolt head, 3. a column block, 4. a screw and 5. a blind hole.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a nut fixing kit structure comprises a nut post body 1 and a bolt, wherein threads are respectively arranged on the inner surfaces of two ends of the nut post body 1, a blind hole 5 is arranged on the outer surface of the nut post body 1, the bolt is provided with a pair and is screwed in from two ends of the nut post body 1, the bolt comprises a bolt head 2 and a screw rod 4, and a post block 3 is integrally formed between the bolt head 2 and the screw rod 4.

The front side and the rear side of the blind hole 5 are inwards recessed.

The bolt head 2 is a hexagonal bolt head 2.

The length of the screw 4 is 1.5 CM-2.0 CM.

The length of the thread is 2.5-3.0 CM.

The concrete implementation process does, to involving the fixed axis body of needs when the jack equipment, insert it to the blind hole 5 that nut post body 1 outside surface set up in, in order to avoid the axis body to meet with great frictional force when interlude, so with both sides inwards sunken setting around the blind hole 5, when the axis body inserts to the blind hole 5 end, the bolt that nut post body 1 both ends set up is screwed up to the inboard, until screw rod 4 head and axis body surface contact, same dismantlement also only needs through unscrewing the screw, the axis body alright take out from blind hole 5, integrated into one piece's post piece 3 between bolt head 2 that the bolt includes and screw rod 4 can make people's finger have great area of contact when screwing up or unscrewing, the effect of difficult finger damage, and the utility model discloses a screw rod 4 length is less than the inside thread length that establishes in nut post body 1 both sides, thereby the axis body of different diameters size is carried out to screw rod 4 regulation at nut post body 1 inboard length of being convenient for And (4) fixing.

The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All changes and modifications that come within the spirit of the invention are desired to be protected.
