Beschreibung
Zusammenfassung:	The pump body assembly comprises an upper flange, an upper air cylinder, a lower air cylinder, a lower flange and a crankshaft which are sequentially arranged, and the crankshaft comprises a long shaft, an upper eccentric shaft, a transition shaft, a lower eccentric shaft and a short shaft which are sequentially arranged; an upper flange hole is formed in the upper flange, an upper flexible groove is formed in the end face of the upper flange, and an upper annular protrusion is formed between the upper flexible groove and the upper flange hole. A lower flange hole is formed in the lower flange, a lower flexible groove is formed in the end face of the lower flange, and a lower annular protrusion is formed between the lower flexible groove and the lower flange hole. The structural strength, vibration reduction and abrasion reduction effects of the flexible grooves are considered, the position relation between the upper flexible groove and the upper tool withdrawal groove, the position relation between the upper
