[0061] This embodiment is used on the basis of embodiment one:

[0062] Before the supporting plate 4 slides out, the connecting sleeve 13 is rotated to separate the connecting sleeve 13 from the air outlet pipe 12, so that the generator as a whole can slide out; at the same time, during use of the generator, since the position of the generator is determined, when the exhaust angle needs to be adjusted, the second air outlet pipe 122 can be rotated to adjust, so that the exhaust direction can be quickly adjusted.
