A pump head includes a casing unit, a tightening member and a control unit. The casing unit includes a main body and an abutment wall connected to the main body. The main body has an installation section. The tightening member is disposed in the installation section proximally to the abutment wall. The control unit includes a control valve, a resilient member and a control lever. The control valve is movably disposed in the installation section. The resilient member urges the control valve toward the abutment wall to clamp the tightening member between the control valve and the abutment wall. The control lever is connected to the main body and operable to move the control valve against the resilient member and away from the abutment wall.
