[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] like Figure 1 As shown, the automobile airbag and steering wheel installation device includes an airbag assembly 10 and a steering wheel assembly 20. The airbag assembly 10 is provided with a box body 1, and a spring 2 is provided in the box body 1. The square disk assembly 20 is provided with a connecting frame 4, which is snap-connected with the box body 1, and the spring 2 abuts against the connecting frame 4. Specifically, the box body 1 is a through groove, and the connecting frame 4 can be snap-connected by passing through the box body 1. The connecting frame 4 and the frame on the steering wheel assembly 20 are integrally formed.

[0024] When in use, the entire airbag assembly 10 is moved so that the box body 1 is aligned with the connecting frame 4 on the steering wheel assembly 20, and then the connecting frame 4 is moved through the box body 1 and the spring 2. Under the elastic force of the spring 2, the connecting frame 4 and the steering wheel assembly 20 are snap-connected.
