The shell 3 is provided with an air outlet hole, and the inflator head is detachably installed in the air outlet hole. The connecting seat 4 is at least partially abutted and installed between the air cock and the shell 3. In this embodiment, the inflator head not only connects the French air cock and the shell 3, but also plays a role in fastening the connecting seat 4, thereby reducing the number of parts on the outer side of the inflator, simplifying the structure and reducing the cost. Specifically, the connecting member is arranged in the air outlet hole and extends axially. The inner side wall of the connecting member is provided with an internal thread, and the connecting member is adapted to be connected with the threaded portion 1313 of the connecting body 1. Meanwhile, the gasket is further arranged between the end of the connecting body 1 and the end of the connecting member, so as to prevent the connecting body 1 from rotating.

[0047] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should be considered as the protection scope of the present application.
