The locking nut 25 is arranged on the left side of the second fixing plate 23. By threading the locking nut 25 to the surface of the limiting rod 24, the hot air blower body 22 can be positioned.

[0029] Embodiment 2:

[0030] See also Figure 3-4 On the basis of the first embodiment, the mounting mechanism 3 further comprises a fixing ring 31, the fixing ring 31 is fixedly connected to the right side of the protective cover body 1, and the fixing ring 31 is threadedly connected with an adjusting bolt 32.
