[0021] The following further describes in detail the embodiments of the utility model in conjunction with the drawings. The following embodiments are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0022] Embodiment:

[0023] As shown in Figure 1 to Figure 4 shown:

[0024] The utility model provides an anti-theft bolt for an automobile chassis suspension, which comprises a bolt body 1. A fixing block 2 is fixedly connected to the top end of the bolt body 1. A limiting ring 3 is fixedly connected to the top end of the fixing block 2. A connecting groove 4 is formed in the top end of the fixing block 2 at the position of the limiting ring 3. An anti-theft column 5 is fixedly connected to the central position of the connecting groove 4. A first thread 6 is arranged on the outer side of the anti-theft column 5. A matching column 7 is movably arranged at the top end of the fixing block 2, and the matching column 7 is located inside the limiting ring 3. A matching groove 8 is formed in the bottom end of the matching column 7. A first thread groove 9 is arranged on the inner wall of the matching groove 8. The first thread groove 9 is movably connected with the first thread 6. A nut 10 is fixedly connected to the top end of the matching column 7.

[0025] Wherein, a second thread groove 11 is formed in the inner wall of the limiting ring 3.

[0026] Wherein, a second thread 13 is arranged on the outer side of the matching column 7. The limiting ring 3 is movably connected with the second thread 13 on the outer side of the matching column 7 through the second thread groove 11.

[0027] Wherein, a clamping groove 12 is formed in the bottom end of the limiting ring 3. The arrangement of the clamping groove 12 can effectively fix the bolt body 1.

[0028] Wherein, both the fixing block 2 and the bolt body 1 are made of stainless steel. The stainless steel material has a longer service life and is durable.

[0029] Wherein, the anti-theft column 5 is made of aluminum alloy.

[0030] Wherein, the matching column 7 and the nut 10 are made of 45# steel.

[0031] The working principle of this embodiment: When the utility model is in use, the installer needs to align the bolt body 1 with the corresponding position of the automobile wheel hub, then place the bolt body 1 into the installation hole of the wheel hub, and then install the nut 10 on the wheel hub through corresponding installation equipment. After the installation is completed, rotate the nut 10 in the reverse direction. The first thread groove 9 and the first thread 6 are separated, and at the same time, the second thread 13 and the second thread groove 11 are separated, so that the matching column 7 can be separated from the connecting groove 4, and at the same time, the matching groove 8 can leave the anti-theft column 5, so that the nut 10 leaves the fixing block 2, and only the fixing block 2 and the bolt body 1 are left on the wheel hub.
