ABSTRACT:
A pumping device includes a main body having a passage defined therein through which air passes, a head connected to the main body, and a retainer slidably received in the head. The retainer includes a first compartment communicated with the passage. The second end of the retainer includes a conical recess defined therein, and a nozzle is slidably mounted in the second end of the retainer. A nozzle head is securely mounted in the second end of the head and includes a second compartment communicated with the first compartment via the nozzle. The nozzle head includes a hollow conical section for engaging with the conical recess of the retainer. A retaining pin is mounted in the first compartment and has a first end secured to the first end of the nozzle to slide therewith. A lever includes a first end pivotally connected to the first end of the head and a second operative end for switching the first end of the retaining pin and the retainer between a first operative position in which the first end of the lever bears against the first end of the retainer and the first end of the retaining pin and a second inoperative position in which the first end of the lever neither engages with the first end of the retainer nor engages with the first end of the retaining pin.
