A fluid dispenser includes an opening 11, a gas inlet 12 and a positioning handle 60 pivotably mounted to a reservoir 10 having an outer tube 20, partially exposed outside the reservoir and having an inner tube 40 in which a pressing rod 50, preferably having a handgrip 51 outside reservoir 10 and a piston 52 within reservoir 10, is slidable. Positioning handle 60 can abut against pressing rod 50, suitably handgrip 51, to prevent pressing rod 50 from moving, for example bouncing upwardly. Reservoir 10 has a relief hole 13, preferably on an annular flange 111, and the positioning handle has a through hole 611, which aligns with relief hole 13 when pressing rod 50 is released, which may allow pressing rod 50 to be reciprocated to pump air into reservoir 10, and which is out of alignment when pressing rod 50 is locked by handle 60, which may prevent gas leakage if a compressed gas is used to pressurize reservoir 10 through gas inlet 12. |
