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

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, and furthermore, unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-4, the present invention provides an embodiment: an anti-theft screw comprises a screw 1 and a screwdriver 8, wherein a connecting block 2 is fixedly connected to the top end of the screw 1, the screw 1 is fixedly connected with the bottom end of the screw through the connecting block 2, the connecting block 2 rotates while the screw 1 rotates, a nut 3 is sleeved outside the connecting block 2, two ends of the connecting block 2 are both fixedly connected with protruding blocks, the protruding blocks are matched with the nut 3 in a clamping mode, the connecting block 2 is prevented from being separated from the nut 3, steel balls 6 are connected between the side walls of the connecting block 2 and the nut 3 in a rolling mode, the nut 3 and the connecting block 2 idle through the steel balls 6, the screw 1 cannot be rotated under the condition that the screw is commonly called as 'sliding screw', the anti-theft effect is achieved, a first cross groove 4 is formed in the middle of the top end of the connecting block 2, and the first cross groove 4 and a second cross groove 5 are vertically formed;

notch 7 has been seted up at 3 middle parts of nut, second cross slot 5 has been seted up to the bottom of notch 7, and second cross slot 5 is the cross, the one end fixedly connected with handle of screwdriver 8, the first cross opening 9 of other end fixedly connected with of screwdriver 8, can only peg graft through traditional screwdriver 8 when using and laminate mutually at notch 7 inside and second cross slot 5, rotate afterwards, the one end fixedly connected with second cross opening 10 of first cross opening 9, through using the supporting screwdriver 8 of specialty, peg graft inside second cross slot 5 and first cross slot 4 through pegging graft first cross opening 9 and second cross opening 10, rotate simultaneously through first cross slot 4 afterwards and drive connecting block 2 and screw 1 and rotate, can realize dismantling.

The working principle is as follows: when the anti-theft screw is used, the screw 1 is the same as the traditional screw 1 in structure, the traditional screwdriver 8 can only be inserted into the notch 7 through the first cross-shaped opening 9 to be attached to the second cross-shaped groove 5, then the screw is rotated, the nut 3 and the connecting block 2 rotate through the steel ball 6 after the screw is rotated, the screw 1 cannot be rotated by the sliding screw, and the anti-theft effect is achieved; then, by using a professional matched screwdriver 8, the first cross-shaped opening 9 and the second cross-shaped opening 10 are inserted into the second cross-shaped groove 5 and the first cross-shaped groove 4, and then the first cross-shaped groove 4 rotates to drive the connecting block 2 and the screw 1 to rotate at the same time, so that the disassembly can be realized; all be unanimous with traditional screw 1 with the shape in the aspect of using, can mistake when illegal molecule uses and think that the smooth silk of inner structure can't dismantle, effectual theftproof effect that reaches.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions on some technical features, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of the present invention.
