the outer side wall of the screw body is provided with a limiting hole, the limiting hole is arranged along the radial direction of the screw body, and the limiting hole is communicated with the connecting hole;
the connecting hole is internally connected with a mandril which can move along the up-and-down direction of the screw body;
a limiting block is connected in the limiting hole, and the ejector rod can eject the limiting block out of the limiting hole;
the front end of ejector pin is equipped with the magnet piece, and the magnet piece can be fixed with stopper and the mutual magnetism of screw body.
The utility model is further provided with a plurality of limiting holes which are uniformly distributed in the circumferential direction of the screw body.
The utility model is further provided that the screw body, the limiting block and the ejector rod are all made of metal iron.
The utility model is further provided that the limiting hole is a square hole.
The utility model is further arranged in such a way that the inner end surface of the limiting block is an inclined surface.
The utility model is further provided that the outer end of the limiting block is of a conical structure.
The utility model is further provided that a limiting spring is arranged in the connecting hole, and the limiting spring is arranged on the upper side of the limiting block.
By adopting the technical scheme, the utility model has the beneficial effects that:
when the screw with the limiting structure is used, the ejector rod moves upwards along with the screwing of the screw, the limiting block is ejected out of the side wall of the screw body through the ejector rod, the protruding limiting block can form the limiting structure, and the screw is further reinforced.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a first schematic structural diagram of the present invention;
fig. 2 is a second structural schematic diagram of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The utility model is illustrated below with reference to fig. 1-2:
the utility model provides a screw with limit structure, includes screw body 1, screw body 1's center be equipped with connecting hole 2, connecting hole 2 sets up along screw body 1's axial, connecting hole 2 run through screw body 1's front end setting.
The outer side wall of the screw body 1 is provided with a limiting hole 3, the limiting hole 3 is arranged along the radial direction of the screw body 1, and the limiting hole 3 is communicated with the connecting hole 2.
The connecting hole 2 is internally connected with a mandril 4, and the mandril 4 can move along the up-and-down direction of the screw body 1.
The limiting hole 3 is internally connected with a limiting block 5, and the ejector rod 4 can eject the limiting block 5 out of the limiting hole 3.
The front end of ejector pin 4 is equipped with magnet piece 6, and magnet piece 6 can be fixed with stopper 5 and the mutual magnetism of screw body 1.
The setting of magnet piece 6 can be fixed ejector pin and stopper on the screw body, avoids ejector pin and stopper to lose.
The limiting holes 3 are arranged in a plurality of numbers, and the limiting holes 3 are uniformly distributed in the circumferential direction of the screw body 1.
The screw body 1, the limiting block 5 and the ejector rod 4 are all made of metal iron.
The limiting hole 3 is a square hole. The limiting block is connected with the limiting hole in an adaptive mode, and the limiting block is prevented from rotating.
The inner end surface of the limiting block 5 is an inclined surface. The inclined plane and the ejector rod form abutting fit so as to conveniently push the limiting block.
The outer end of the limiting block 5 is of a conical structure.
The connecting hole 2 is internally provided with a limiting spring 7, and the limiting spring 7 is arranged on the upper side of the limiting block 5. The arrangement of the limiting spring 7 enables the ejector rod to move downwards to reset.
By adopting the technical scheme, the utility model has the beneficial effects that:
when the screw with the limiting structure is used, the ejector rod 4 moves upwards along with the screwing of the screw, the limiting block 5 is ejected out of the side wall of the screw body 1 through the ejector rod 4, and the protruding limiting block 5 can form the limiting structure and further reinforce the connection of the screw.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
