Zusammenfassung:	The utility model discloses a lantern ring type pin shaft anti-retreating structure, a plurality of cargo boom frame sections are arranged, the plurality of cargo boom frame sections are sequentially connected end to end, a cargo boom frame upper chord is fixedly arranged at the top of each cargo boom frame section, and a cargo boom frame lower chord is fixedly arranged at the bottom of each cargo boom frame section. The connecting pin shaft is arranged at the joint of the two lower chords of the cargo boom in a penetrating mode and penetrates through the first mounting hole and the second mounting hole, so that the annular groove of the shaft body of the connecting pin shaft is completely exposed out of the outer plane of the second lug plate, the two retaining semi-rings are clamped into the annular groove of the shaft body of the connecting pin shaft, and meanwhile the retaining semi-rings are sleeved with the anti-disengaging ring sleeve. And finally, the cotter pin body is assembled, so that the anti-fal
