1. An air compressing device comprising: a cylinder housing,a piston slidably engaged in said cylinder housing,a piston rod extended from said piston, anda motor attached to said cylinder housing and coupled to said piston rod with a coupling device for moving said piston relative to said cylinder housing in a reciprocating action, in order to generate a pressurized air,said cylinder housing including an outlet tube extended outwardly therefrom and communicating with said cylinder housing for receiving the pressurized air from said cylinder housing, and including an outlet port provided on said outlet tube and having a bore formed in said outlet port and communicating with said outlet tube for receiving the pressurized air from said outlet tube and said cylinder housing, and including an anchor plate extended from said outlet port, anda facility including a coupler for engaging with said outlet port and said anchor plate and for detachably securing said coupler and said facility to said outlet port of said outlet tube and for allowing the pressurized air to be supplied to said facility, said coupler including a base plate, and two arms extended from said base plate and spaced from each other for forming a space between said arms and for forming a retaining space in said coupler and for engaging with said anchor plate, and said coupler including an inwardly folded flange extended from each arm for partially closing said space and for engaging with said anchor plate, and said anchor plate including two rounded corners oppositely formed thereon for allowing said coupler to be rotated relative to said anchor plate, said facility including a mouth extended into said coupler for engaging into said bore of said outlet port of said outlet tube. 2. The air compressing device as claimed in claim 1, wherein said anchor plate includes a width greater than a height of said anchor plate for forming a rectangular structure. 3. The air compressing device as claimed in claim 1, wherein said outlet port is formed on a free end portion of said outlet tube and aligned with said outlet tube. 4. The air compressing device as claimed in claim 1, wherein said outlet port is laterally extended from said outlet tube. 5. The air compressing device as claimed in claim 1, wherein said facility is a hose. 6. The air compressing device as claimed in claim 1, wherein said facility is a relief valve. 7. The air compressing device as claimed in claim 1, wherein said facility is a pressure gauge. 8. The air compressing device as claimed in claim 1, wherein said facility is a cover. 9. The air compressing device as claimed in claim 8, wherein said cover includes a knob extended therefrom. 10. The air compressing device as claimed in claim 1, wherein said cylinder housing includes a valve seat disposed and located between the cylinder housing and the outlet tube, and a check valve device disposed in said outlet tube and engaged with said valve seat for controlling the pressurized air to selectively flow into said outlet tube only and for preventing the pressurized air from flowing back form said outlet tube into said cylinder housing. 11. The air compressing device as claimed in claim 1, wherein a receptacle is further provided and includes a chamber formed therein for receiving said outlet tube and said cylinder housing and said motor and said facility.
