However, the existing nuts have the following disadvantages: when the two shear blades rotate mutually, the shear blade positioned on one side of the screw can easily rub the screw while rotating, so that the screw is loosened relative to the nut after long-time use, and the shearing tool is inconvenient to use.

SUMMERY OF THE UTILITY MODEL

To the not enough among the above prior art, the utility model aims at providing a locknut.

In order to achieve the above purpose, the utility model discloses the technical scheme who takes does: the utility model provides a locknut, is including the nut body that has the screw hole, and the nut body includes that shoulder and external diameter are less than the axial region of shoulder, and the screw hole axial runs through in the center of axial region, and the axial region includes first end and second end, and the shoulder sets up in the second end of axial region, and the first end of axial region is equipped with the breach, and the lateral surface of axial region between breach and the shoulder is smooth surface.

In the scheme, the notch is formed in the first end of the shaft part, when the nut is used, the shaft part of the nut body is inserted into the connecting hole of the two shear blades of the shearing tool, and then the screw is screwed into the threaded hole of the nut body and is connected with the nut body, so that the nut body is used as the rotating shaft of the shearing tool. Wherein, the connecting hole inboard of the clip that is located first end one side of axial region can cooperate with the breach of axial region to make the unable relative axial region of this clip rotate, and the head of screw also is located first end one side position, just so makes this clip can not produce the friction with the screw, thereby avoids the relative nut body of screw to appear not hard up phenomenon, and the clip that is located second end one side of axial region can rotate through its relative axial region of connecting hole, guarantees shear tool's normal use.

Furthermore, the shoulder part and the shaft part are concentrically arranged, and the threaded hole of the nut body axially penetrates through the shaft part and the shoulder part so as to be suitable for being matched with a screw with a long length for use.

Furthermore, the outer side surface of the shaft part between the notch and the shoulder part is a circumferential surface, so that the shear blade positioned on the side is convenient to be in rotating fit with the shaft part of the part.

Furthermore, the notch is a plane notch, and the notch is arranged on the outer side surface of the first end of the shaft part, so that the notch is convenient to arrange.

Furthermore, the two notches are arranged at two outer side positions, opposite to the first end of the shaft part, of the two notches respectively, so that the shear blades at the ends are better prevented from rotating.

Another object of the utility model is to provide a scissors that can avoid the screw not hard up.

In order to achieve the above purpose, the utility model discloses the technical scheme who takes does: the utility model provides a scissors, including left shear blade and right shear blade, the left handle piece of being connected with left shear blade, and the right handle piece of being connected with right shear blade, still include like foretell locknut and the screw of being connected with locknut, first connecting hole has been seted up to left shear blade, the second connecting hole has been seted up to right shear blade, the axial region of nut body inserts in first connecting hole and the second connecting hole, the second connecting hole inboard of right shear blade cooperatees with the breach of axial region, left shear blade can rotate through the relative axial region of first connecting hole, and the threaded hole of screw in nut body, left shear blade and right shear blade are located the position between the head of shoulder and screw.

In the above scheme, the second connecting hole through with the right shear blade cooperatees with the breach of axial region to can prevent that the relative axial region of right shear blade from rotating, just so can not make right shear blade and screw produce the friction, thereby avoid the relative nut body of screw not hard up phenomenon to appear. The shoulder and the head of the screw can limit the left shear blade and the right shear blade, and the left shear blade and the right shear blade are prevented from moving towards the left side and the right side in the rotating process. And the left shear blade can rotate relative to the shaft part through the first connecting hole, so that the left shear blade can be sheared and separated relative to the right shear blade, and the normal use of the scissors is ensured.

Furthermore, the first connecting hole is a circular hole, so that the left shear blade can rotate more smoothly.

The utility model has the advantages that: locknut can regard as shear means's axis of rotation to use, can avoid being located the relative nut body rotation of the relative nut of the clip of screw one side to avoid this clip and screw to produce the friction and appear not hard up phenomenon. For example be used for locknut the utility model discloses an on the scissors, through the breach cooperation of the inboard and axial region of second connecting hole to prevent that the relative axial region of right shear blade from rotating, just so can not make right shear blade and screw produce the friction, avoid the relative nut body of screw not hard up phenomenon to appear well, guarantee the structural stability of scissors, and can not influence the normal shearing of scissors and close and separate, it is more convenient, durable to use.
