The invention belongs to the field of a strong-magnetic positioning roof-pressure plugging device, particularly discloses a spider crawling type strong-magnetic self-adaption positioning quick plugger and a decompression and diversion airbag, and solves the technical problems that the plugging surface of an existing plugging tool cannot be changed when the surface shape of a plugged body is changed, i.e. the plugging surface does not have the feature of flexible change. The technical scheme is that the quick plugger comprises a strong-magnetic plugging mechanism, a quick positioning mechanism and a decompression and diversion mechanism; the strong-magnetic plugging mechanism comprises a rubber balloon, the quick positioning mechanism comprises a universal follow-up pressing disc, wherein a connecting handle is arranged all around the universal follow-up pressing disc, one end of the connecting handle is hinged to the universal follow-up pressing disc, and the other end of the connecting handle is hinged with a magnetic seat through a spherical hinge; the decompression and diversion mechanism comprises a diversion pipe; the upper part of the diversion pipe is provided with a quick plug, a diversion ball valve is arranged at the diversion pipe below the quick plug, and the diversion pipe penetrates through a mounting hole formed in the center of the universal follow-up pressing disc and then is connected with a diversion hole in a threaded way.
