In the process of pulling the power supply device 3 upward, the upward pulling force applied by the power supply device 3 to the bracket 2 is dispersed by the second connecting part 22 into a vertical upward force and a horizontal force, so that the upward force on the top of the shell 10 is reduced, thereby achieving the effect of reducing the probability of the top of the shell 10 bulging upward and deforming, so that the gap between the inner wall of the shell 10 and the body does not increase, while ensuring that the gap between the outer wall of the shell 10 and the power supply device 3 does not decrease, thereby improving the aesthetics of the power supply device 3 and the air compressor 1 as a whole.

[0034] Further, the bracket 2 further comprises a third connecting part 23, the second connecting part 22 is connected with the first connecting part 21 through the third connecting part 23, and the third connecting part 23 is arranged perpendicularly to the first connecting part 21.

[0035] Further, the bottom surface of the first connecting part 21 is connected with the top surface of the shell 10, so as to improve the stability of the connection between the first connecting part 21 and the shell 10.
