Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1 is referred to, the utility model improves and is：The fast adjustment mechanism of novel transfusion device gear drop includes that one is spherical outer
Shell, spherical housing top is provided with liquid inlet joint 110, and bottom is provided with out liquid joint 19, and the center of spherical housing is provided with distribution ball 8,
