Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides an embodiment: a bolt with an anti-theft structure comprises a nut 1, a first lug 2 is welded on the upper side of the left end of the nut 1, a second lug 3 is arranged at the lower end of the left side of the nut 1, the first lug 2 and the second lug 3 are lugs with equal size, the structural plan view of the first lug 2 is in a fan shape, the left side of the first lug 2 is a vertical surface, the right side of the first lug 2 is an inclined surface, the structural plan view of the second lug 3 is in a fan shape, the right side of the second lug 3 is a vertical surface, the left side of the second lug 3 is an inclined surface, the vertical surface of the first lug 2 is positioned above the inclined surface of the second lug 3, the inclined surface of the first lug 2 is positioned above the vertical surface of the second lug 3, the first lug 2 and the second lug 3 are installed in an object manner, the structure enables the device to be stressed only on the vertical surfaces of the first lug 2 and the second lug 3, so that the device can only rotate clockwise, the first lug 2 and the second lug 3 have no stress points rotating anticlockwise, so the device cannot be taken down by a conventional means, and a certain anti-theft effect is achieved;

the left end of the nut 1 is internally connected with the sliding block 5 through the spring 4, a groove is formed in the left end of the nut 1, the inner side size of the groove is equal to the outer side size of the right end of the sliding block 5, the sliding block 5 is arranged into a telescopic structure through the spring 4, and the structure can apply opposite force to the gasket 7 and the nut 1 through the characteristic of the spring 4 after the device is finished, so that the external thread of the device is tightly attached to the internal thread of the fixing piece, the friction force at the joint is increased, and the bolt is more stable and is not easy to loosen;

the left end of the nut 1 is fixedly connected with the right end of the first screw 6, the gasket 7 is sleeved on the outer side of the first screw 6, circular holes are formed in the sliding block 5 and the gasket 7, the inner side size of each circular hole is equal to the outer side size of the right end of the first screw 6, the sliding block 5 and the gasket 7 are in sliding connection with the first screw 6, anti-slip grains are arranged on the left surface of the gasket 7, and the gasket 7 and the sliding block 5 can move on the first screw 6 conveniently due to the structure;

the left end of first screw rod 6 is connected with second screw rod 9 through first connecting rod 8, second screw rod 9 is connected with third screw rod 11 through second connecting rod 10, the inside of first connecting rod 8 and second connecting rod 10 all sets up to hollow structure, this structure is used for when the longer unable use of bolt, can cut in first connecting

rod

8 and 9 departments of second screw rod, with the length of reducing the bolt, be hollow structure because of first connecting rod 8 and second screw rod 9, it is comparatively simple to cut, avoid simultaneously leading to this device unable use because of the cutting contains the screwed screw rod.

The working principle is as follows: before the device is used, if the length of the screw rod needs to be adjusted, the first connecting rod 8 or the second connecting rod 10 can be cut, and the first connecting rod 8 and the second connecting rod 10 are of hollow structures, so that the cutting is convenient, and threads of other parts cannot be touched;

when the device is used, the left end of the third screw rod 11 is aligned to the preformed hole on the fixing piece, then a tool is used for passing through the vertical surfaces of the first lug 2 and the second lug 3 to rotate the device clockwise until the left end of the first screw rod 6 is submerged into the preformed hole, the gasket 7 on the first screw rod 6 is tightly attached to the fixing piece at the moment, the anti-skid lines on the gasket 7 can increase the friction force between the anti-skid lines and the contact surface, so that the bolt is more stable, in addition, after the device is installed, the sliding block 5 is tightly attached to the gasket 7, the sliding block 5 enables the spring 4 to be in a compression state, due to the characteristics of the spring 4, when the spring is stressed, the force can be absorbed and rebounded, the spring 4 can release the force on the left end of the nut 1 and the gasket 7, so that the nut 1 can receive a rightward force, so that the external threads on the screw rod can be tightly attached to the internal threads connected with the, cause the junction more stable, the extending structure that slider 5 and spring 4 constitute simultaneously, can produce when rocking at the mounting, weaken vibrations and to the influence that this device produced, in addition, only one side is the perpendicular because of first lug 2 and second lug 3, make nut 1 only accessible first lug 2 and second lug 3 carry out clockwise rotation, after its installation finishes, because of the another side of first lug 2 and second lug 3 is the inclined plane, do not have the stress point to carry out the atress, so nut 1 can't carry out clockwise rotation, make this device can't be twisted off through conventional means, so certain theftproof effect has been played, it is above the utility model discloses a whole theory of operation.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
