The five-compressing-chamber diaphragm pump with multiple effects as claimed in  claim 27 , wherein an integral dented ring is circum-disposed around the upper side of each operating hole and a linking five-curved dent is disposed to encompass all five integral dented rings in the pump head body while an integral protruded ring is circum-disposed around each concentric annular positioning protrusion and a linking five-curved protrusion is disposed to encompass all five integral protruded rings at the bottom side of the diaphragm membrane in corresponding position with the mating linking five-curved dent and five integral dented rings in the pump head body. 
     
     
         49 . The five-compressing-chamber diaphragm pump with multiple effects as claimed in  claim 48 , wherein said linking five-curved dent and five integral dented rings in the pump head body are adapted into a linking five-curved slit and five integral perforated rings. 
     
     
         50 . The five-compressing-chamber diaphragm pump with multiple effects as claimed in  claim 48 , wherein said linking five-curved dent and five integral dented rings in the pump head body and the corresponding linking five-curved protrusion and five integral protruded rings in the diaphragm membrane are exchanged into a linking five-curved protrusion and five integral protruded rings in the pump head body and a corresponding linking five-curved dent and five integral dented rings in the diaphragm membrane without affecting their mating condition so that the linking five-curved protrusion and five integral protruded rings at the upper side of the pump head body completely insert into the corresponding linking five-curved dent and five integral dented rings at the bottom side of the diaphragm membrane upon assembly of the pump head body and the diaphragm membrane, as well as a short length of moment arm from the integral dented ring to the peripheral of the annular positioning protrusion in the diaphragm membrane is also obtained. 
     
     
         51 . The five-compressing-chamber diaphragm pump with multiple effects as claimed in  claim 27 , wherein said cylindrical eccentric roundel is modified into an inverted conical frustum eccentric roundel in an eccentric roundel mount such that said conical frustum eccentric roundel basically comprises an integral inverted conical frustum flank and a sloped top ring, which is created from an annular positioning dent to the inverted conical frustum flank, as well as the outer diameter of the conical frustum eccentric roundel is enlarged but still smaller than the inner diameter of the operating hole in the pump head body. 
     
     
         52 . The five-compressing-chamber diaphragm pump with multiple effects as claimed in  claim 51 , wherein said cylindrical eccentric roundel is adapted into a combinational eccentric roundel of a roundel mount and an inverted conical frustum roundel yoke in detachable separation in an eccentric roundel mount such that the outer diameter of the conical frustum roundel yoke is enlarged but still smaller than the inner diameter of the operating hole in the pump head body, wherein said roundel mount, which is a two-layered frustum, includes bottom-layer base with a positional crescent facing inwardly and a top-layer protruded cylinder with a central female-threaded bore; and said inverted conical frustum roundel yoke, which is to sleeve over the corresponding roundel mount, includes an upper bore, a middle bore and a lower bore stacked as a three-layered integral hollow frustum, as well as an inverted conical frustum flank and a sloped top ring created from the upper bore to the inverted conical frustum flank such that the bore diameter of the upper bore is bigger than the outer diameter of the protruded cylinder, the bore diameter of the middle bore is equivalent to the outer diameter of the protruded cylinder while the bore diameter of the lower bore is equivalent to the outer diameter of the bottom-layer base in the roundel mount, and a positioning dented ring created between the protruded cylinder and the inside wall of the upper bore upon having the conical frustum roundel yoke sleeved over the roundel mount.
