In other embodiments, depending on the force bearing surface 612 of the selection push block 61, a tension spring, a compression spring or a torsion spring is selected as the spring 62 according to the actual situation when the temperature control bead 63 is not broken.
In other embodiments, the mounting positions of the telescopic sleeve 11 and the telescopic rod 21 may be interchanged, i.e. the telescopic sleeve 11 is mounted on the fan 7 and the telescopic rod 21 is mounted on the frame 8.
While the invention has been described with reference to preferred embodiments, it is not intended to be limiting. Many possible variations and modifications of the disclosed technology can be made by anyone skilled in the art, or equivalent embodiments with equivalent variations can be made, without departing from the scope of the invention. Therefore, any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present invention shall fall within the scope of the technical solution of the present invention.
