a concave part which is spirally arranged on one end of the first screw rod with the drill bit;

the second screw is connected to the first screw, and one end of the second screw is provided with a positioning block matched with the groove;

the limiting hole penetrates through the screw rod and the positioning block;

and the limiting rod is arranged in the limiting hole.

In this technical scheme, this bolt is convenient to be installed in any position, can adjust at will as required to the second screw rod that sets up can connect in the recess of first screw rod and form a complete screw rod with the screw thread relatively, install the gag lever post into the spacing hole again, fixed first screw rod is connected with the second screw rod, can overlap a plurality of second screw rods as required, constitutes the screw rod of different length.

In the above technical solution, further, the groove is hexagonal.

In this technical scheme, the screw thread position of first screw rod and second screw rod can be fixed a position to hexagonal recess to when the nut damages, can use hexagonal spanner to insert the recess and twist and rotate.

In the above technical scheme, further, the first screw is internally provided with a liquid injection hole, and the liquid injection hole penetrates from the inside of the groove to the surface of the concave part.

In this technical scheme, the notes liquid hole that sets up in the screw rod can inject different liquid, when twisting smooth inadequately, can inject lubricating oil, when the installation is accomplished, can inject glue and carry out further fixation.

In the above technical scheme, further, the surface of the drill bit is provided with arc-shaped cutting teeth.

In the technical scheme, the circular arc-shaped cutting teeth arranged on the surface of the drill bit can enable the cutting capacity of the drill bit to be stronger, and enable the cutting efficiency of the drill bit to be higher.

The beneficial effects of the utility model are as follows:

1. the length of the bolt can be adjusted.

2. The liquid injection holes can be used for injecting lubricating oil and glue.

Detailed Description

The technical solutions of the embodiments of the present utility model will be clearly described below with reference to the drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present utility model, fall within the scope of protection of the present utility model.

Example 1:

the present embodiment provides a stud bolt including:

the first screw 1 is provided with a groove 5 on the end face of one end of the first screw 1;

the nut 2, the nut 2 is fixed in the middle of the first screw 1;

a drill bit 3, the drill bit 3 being arranged on the other end of the first screw 1;

a concave portion 4, the concave portion 4 being spirally provided on one end of the first screw 1 having the drill bit 3;

the second screw rod 9 is connected to the first screw rod 1, and one end of the second screw rod 9 is provided with a positioning block 10 matched with the groove 5;

the limiting hole penetrates through the screw and the positioning block 10;

the limiting rod 6, the limiting rod 6 sets up in the spacing downthehole.

The embodiment is a novel stud bolt, which can be used on a wood board without other methods for fixing, and is characterized in that one end with a drill bit 3 is abutted against an installation part, such as the wood board, the stud bolt is screwed, the drill bit 3 can be drilled into the wood board, the nut 2 is hexagonal, and a tool is conveniently used for screwing in the wood board and is screwed down; the recess 4 can cut the plank to the plank piece of cutting can be discharged outward from the recess 4, then the screw rod of opposite side is convenient to install other parts, and easy to assemble is in any position, can adjust at will as required, and the second screw rod 9 that sets up can connect in the recess 5 of first screw rod 1 and form a complete screw rod with the screw thread relatively, installs gag lever post 6 into the spacing hole again, fixes the connection of first screw rod 1 and second screw rod 9, can overlap a plurality of second screw rods 9 as required, constitutes the screw rod of different length.
