Press structure for pump head

A press structure for a pump head comprising:

• a base body provided with a hollow space portion inside, the hollow space portion being disposed with an air inlet and at least one air outlet, at least one supporting portion being disposed on an outer side of the base body;
• an inflating unit having at least one valve plug disposed on an inner side of each said at least one air outlet, an interface being provided on the valve plug;
• at least one hanging arm having a force-bearing end and a clamping end, each said at least one hanging arm straddling the at least one supporting portion of the base body, the force-bearing end being pressed by using the at least one supporting portion as a fulcrum, the clamping end being disposed on an outer side of the interface of the valve plug, when the force-bearing end being pressed, the clamping end displacing away from a direction of the interface;
• at least one elastic member disposed between the base body and each said corresponding at least one hanging arm and elastically pushing the force-bearing end to make the clamping end moving toward a direction of the interface, when the force-bearing end being pressed, the at least one elastic member being compressed to generate an elastic restoring force;
• and
• at least one end cap, each said at least one end cap being disposed on a periphery of each said at least one air outlet of the base body, a through hole being formed on each said at least one end cap and corresponded to the interface of the inflating unit, and each said at least one hanging arm being disposed between the base body and the said corresponding at least one end cap.
