Zusammenfassung:	The utility model relates to the field of well cementation cement heads for oil and gas well cementation, in particular to a stop pin device of a well cementation cement head. According to the well cementation cement head stop pin device, the stop pin is the swing type stop pin which can be installed in the stop pin containing groove in a swing mode, when the stop pin is locked to the stop position through the stop pin locking mechanism, the stop pin extends out of the stop pin containing groove, a rubber plug in a cement head sleeve can be prevented from moving downwards, and therefore the well cementation cement head sleeve can be prevented from moving downwards. When the stop pin is unlocked from the stop position through the stop pin locking mechanism, the stop pin is withdrawn into the stop pin containing groove and can avoid the rubber plug in the cement head sleeve, so that the rubber plug moves downwards. Therefore, according to the well cementation cement head stop pin device, the stop pin can stop a
