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.

1. A fluid supplying device, including: a reservoir, having an opening and a gas inlet, the opening being located at a top of the reservoir, the top of the reservoir further forming a relief hole;a cover, disposed on the opening of the reservoir and being hollow, a lateral side of the cover forming a fluid outlet;an outer tube, an end of the outer tube extending into the reservoir, an opposite end of the outer tube extending through the cover, the outer tube communicating with the fluid outlet;an inner tube, disposed in the outer tube, an end of the inner tube extending into the reservoir;a pressing rod, slidably disposed in the inner tube, an end of the pressing rod away from the reservoir extending outside the cover;a positioning handle, an end of the positioning handle being pivotably disposed on the top of the reservoir, the positioning handle being able to pivot between a first position and a second position, the positioning handle further forming a through hole;wherein when the positioning handle is located at the first position, an end of the positioning handle away from the reservoir abuts against the end of the pressing rod away from the reservoir so that the pressing rod is unable to move along the inner tube, the through hole is positionally deviated from the relief hole so that the relief hole does not communicate inside the reservoir and exterior therebetween;wherein when the positioning handle is located at the second position, the end of the positioning handle away from the reservoir is away from the pressing rod and does not abut against the pressing rod so that the pressing rod is able to move up and down, the through hole positionally corresponds to the relief hole so that the relief hole communicates with exterior via the through hole. 2. The fluid supplying device of claim 1, wherein an annular flange extending outward is formed at the opening of the reservoir, the relief hole is formed on the annular flange, the positioning handle is pivotably disposed to the annular flange, the cover is disposed at a space enclosed by the annular flange. 3. The fluid supplying device of claim 2, wherein the positioning handle has a first end and a second end, two parallel pivot arms arranged spacedly are formed at the first end, the two pivot arms are pivotably disposed to two opposite sides of the annular flange respectively, the through hole is formed on one of the pivot arms, a restriction groove facing the pressing rod is formed at the second end of the positioning handle, the end of the pressing rod away from the reservoir has a handgrip, when the positioning handle is located at the first position, the handgrip is restricted in the restriction groove and is unmovable, the through hole is deviated from the relief hole and does not communicate with the relief hole. 4. The fluid supplying device of claim 3, wherein circumferential walls of the restriction groove extend to the two pivot arms so that the positioning handle is substantially U-shaped. 5. The fluid supplying device of claim 1, wherein a switch is disposed at the gas inlet to alternatively allow the gas inlet to communicate the reservoir and exterior therebetween.
