Abstract
A fluid supplying device of the present invention includes a reservoir, an outer tube, an inner tube disposed in the outer tube, a pressing rod, and a positioning handle. The outer tube disposed in the reservoir and is partially exposed outside the reservoir. The pressing rod is slidably disposed in the inner tube. The positioning handle is pivotably disposed to the reservoir and is able to altervatively abut against the pressing rod to prevent the pressing rod from moving. The reservoir forms a relief hole, and the positioning handle forms a through hole. When the pressing rod is restricted by the positioning handle, the relief hole is deviated from the through hole, and vice versa. Thereby, the present invention can prevent gas-leakage and prevent the pressing rod from bouncing up.
