The invention discloses a detachable double-locking riveting dismounting method and a pulling rivet. A lantern ring comprises a thin-wall hook section, a thick-wall locking section and a lantern ring head with an annular step from front to back. The rivet comprises a rivet head of an annular groove matched with the hook section, a front polish rod section, a knurling section matched with the locking section, a separating groove, a rear polish rod and a tail annular groove section from front to back. Double riveting is used by inserting the rivet and lantern ring from both sides; after riveting, the locking section and knurling section form radial locking, and the hook section is buckled to form axial locking. Simple detaching tools (e.g. front snap ring and center cylinder) are equipped to dismount rivets rapidly.
