Beschreibung
Zusammenfassung:	A quick connecting device comprises an elastic connector, a connecting rod, a piston rod connector and a U-shaped bolt. A counter bore is formed in the right end face of the elastic connector along the axis, fan-shaped grooves are symmetrically formed in the two ends of the counter bore, and a first annular groove is formed in the left end of each fan-shaped groove of the elastic connector. The connecting rod comprises a connecting rod head and a connecting rod body; the connecting rod head is a big-end-right cylinder, a disc is arranged in the middle of the left end face of the connecting rodhead, fan-shaped faces are symmetrically arranged at the two ends of the disc, the thickness of the fan-shaped faces is matched with the depth of the first annular groove, the fan-shaped faces are matched with the fan-shaped groove in the right end face of the elastic connector, and a third annular groove is formed in the right side of the connecting rod body; the piston rod connector is a cylindrical table, a step throu
