1. A device for inspecting a canister for a vehicle, the device comprising: an inspection unit fixing a canister and inspecting airtightness of the canister using pressure of air supplied from an external supply source; anda control unit controlling the pressure of the air and showing inspection process and result of the canister,wherein the inspection unit includes one or more inspection jigs for fixing the canister and inspecting airtightness of the canister using pressure of air, and the inspection jigs are circumferentially arranged on a circular rotary plate,wherein each inspection jig includes: a seating unit where the canister is seated;a spraying unit connected with any one of an air port, a purge port, and a tank port of the canister and injecting air supplied through a hub connected with the supply source into the canister;a closing unit connected with at least one or more other ports not connected with the spraying unit and preventing air from being discharged out of the canister; andan inspection plate where the units are disposed and fixed. 2. The device of claim 1, wherein the rotary plate is connected to a motor of an actuating unit and rotated in one or opposite directions. 3. The device of claim 1, wherein each inspection jig further includes an inclining mechanism disposed between the inspection plate and the rotary plate and adjusting inclination of the inspection plate. 4. The device of claim 3, wherein the inclining mechanism includes: an inclining plate where the inspection plate is seated; andan inclining unit adjusting inclination of the inclining plate. 5. The device of claim 1, wherein the seating unit includes: a seating groove where the canister is seated; andsupports preventing the canister from separating to a side by supporting sides of the canister. 6. The device of claim 5, wherein the seating unit further includes a metal sensor inspecting whether there is an internal metal component in the canister so that inspection result is shown in a display unit. 7. The device of claim 1, wherein the spraying unit includes: a spraying cylinder longitudinally extending a spraying rod such that the spraying rod is connected to one of the ports, using pressure of air supplied through the hub; anda spraying packing reinforcing airtightness between an outer side of the spraying rod and an inner side of the port, andthe spraying rod is a pipe having an end connected to the hub so that air is supplied to the canister through a channel. 8. The device of claim 1, wherein the closing unit includes: a closing cylinder longitudinally extending a closing rod using pressure of air supplied through the hub;a closing plate combined with the closing rod and having holes keeping and closing the other ports; andclosing packings disposed in the holes and reinforcing airtightness between the holes and the other ports. 9. The device of claim 8, wherein the closing plate includes: a first closing panel having the holes and combined with the closing rod; anda second closing panel disposed between the first closing panel and the closing cylinder, having closing channels connected with the holes, and guiding the first closing panel, andthe closing channels are connected with the hub through air hoses and close the other ports using pressure of air corresponding to pneumatic pressure of the spraying unit. 10. The device of claim 1, wherein each inspection jig further includes a clamp unit preventing separation of the canister by covering a side of the canister such that the canister is in contact with the seating unit, and keeping the canister fixed through the control unit when there is a defect. 11. The device of claim 10, wherein the clamp unit includes: a clamp cylinder rotating and longitudinally extending and retracting a clamp rod by taking inside and discharging air; anda clamp bar connected with the clamp cylinder and fixing or releasing the canister. 12. The device of claim 1, wherein each inspection jig further includes a marking unit marking quality authentication for the canister. 13. The device of claim 12, wherein the marking unit includes: a marking cylinder longitudinally extending the marking rod using pressure of air supplied through the hub; anda stamp connected with the marking rod and marking a side of the canister. 14. The device of claim 1, wherein the inspection unit further includes motion sensors stopping operation when sensing a worker entering the inspection unit while the inspection unit is operated. 15. The device of claim 1, wherein the control unit includes: a setting unit for correcting and supplementing operation of the inspection unit and pressure or air; anda monitor displaying an operation and a process of the inspection unit. 16. The device of claim 1, wherein the control unit includes a printer giving codes so that inspection history of the canister and information about a product can be checked. 17. The device of claim 16, wherein the printer outputs a barcode or a QR (Quick Response) code on a sticker. 18. The device of claim 1, wherein the inspection unit further includes an operation unit restricting operation control and selective operation of the inspection jigs. 19. The device of claim 1, further comprising an alarm unit producing at least any one of a voice and light warning in cooperation with the control unit in an inspection process when a defect of the canister is detected. 20. A device for inspecting a canister for a vehicle, the device comprising: an inspection unit fixing a canister and inspecting airtightness of the canister using pressure of air supplied from an external supply source; anda control unit controlling the pressure of the air and showing inspection process and result of the canister,wherein the control unit includes a printer giving codes so that inspection history of the canister and information about a product can be checked,wherein the printer outputs a barcode or a Quick Response (QR) code on a sticker.
