[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] See also Figures 1 to 4 In the utility model, an automobile fastener with an anti-scratch bolt structure includes a bolt body 1, which includes a spiral column 2 and a nut 3. The outer side of the spiral column 2 is threadedly connected to a nut 4, and the outer side of the nut 4 is slidably connected to a sliding disk 5. A limiting tooth 6 is provided on the left side of the sliding disk 5, and a counter tooth 7 is provided on the right side of the nut 3. An elastic mechanism 8 is installed between the outer side of the nut 4 and the sliding disk 5.

[0022] When the screw thread 2 is tightened, the nut 3 is tightened and the screw thread 2 is tightened, and the nut 3 is tightened. When the screw thread 2 is tightened, the nut 3 is tightened and the nut 3 is tightened, the nut 3 is tightened and the nut 3 is tightened. When the screw thread 2 is tightened, the nut 3 is tightened and the nut 3 is tightened, the nut 3 is tightened and the nut 3 is tightened. When the screw thread 2 is tightened, the nut 3 is tightened and the nut 3 is tightened, the nut 3 is tightened and the nut 3 is tightened.

[0023] See also Figure 1 and Figure 3 , wherein: the elastic mechanism 8 includes a positioning ring 81 and a ring-distributed spring group 82, the inner side of the positioning ring 81 is fixedly connected to the outer side of the nut 3, one end of the spring group 82 is fixedly installed on one side of the positioning ring 81, and the other end of the spring group 82 is fixedly connected to the sliding disk 5.

[0024] In the present invention, the positioning ring 81 cooperates with the spring group 82. When tightening, as the spiral column 2 is tightened, the sliding disk 5 is squeezed to move the squeezing spring group 82, and the spring group 82 generates reverse pressure on the sliding disk 5, so that when the spiral column 2 becomes loose, the anti-locking tooth 7 on the sliding disk 5 has a better locking effect on the limiting lock tooth 6.

[0025] See also Figure 1 , wherein: the left side of the sliding disk 5 extends out of the left side of the nut 4.

[0026] In the present invention, the left side of the nut 4 is extended from the left side of the sliding plate 5, so that the sliding plate 5 has a redundant distance for linear movement.

[0027] See also Figure 1 , wherein: two through holes 31 are opened inside the nut 3.

[0028] In the present invention, a straight rod is used through the two through holes 31 to push the counter-grip 7 and the limit gripping tooth 6 to separate linearly, so as to realize the disassembly of the entire spiral.

[0029] See also Figure 2 , wherein: a guide groove 41 is opened on the outer side of the nut 4, and the inner side of the sliding plate 5 is slidably connected to the inside of the guide groove 41.

[0030] In the present invention, the guide groove 41 allows the sliding plate 5 to slide only in a straight line and not to rotate.

[0031] See also Figure 1 , wherein: the outer diameter of the sliding disk 5 is larger than the outer diameter of the counter-grip 7.

[0032] In the present invention, the outer diameter of the sliding plate 5 is larger than the outer diameter of the reverse latching teeth 7, so that the squeezing operation during disassembly is facilitated.

[0033] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
