ABSTRACT:
A dust collector with an invertible wind exhausting case includes a wind exhausting case having an upper and lower cover, which is respectively provided with two threaded holes of the same size in two lateral sidewalls. Two bolts combine tightly the lower cover with each of two upper horizontal tubes of two upper side frames of a platform truck, by screwing the threaded holes. The threaded holes of the upper cover are sealed up with bolts. In case the position of the fan motor and the sucking tube vase is needed to be inverted upside down, it is enough to screw loose the seal bolts of the platform truck and those of the upper cover and then the wind exhausting case can be inverted upside down and then seal bolts are screwed tight again. Thus the inverting work of the invention is much more simplified than a conventional one.
