The invention discloses a compound pickproof plug, and relates to the field of plugs. The compound pickproof plug solves the problems that an existing plug shell of a door cannot be completely inserted into a plug hole of a door frame sometimes, and it is difficult to use the plug shell. The periphery of the inner end and the inner side of the plug shell of the compound pickproof plug are provided with circle-shaped limiting edges and blocking edges respectively. The peripheral portion of the top end of the plug shell is provided with three or more swing bolt holes corresponding to swing bolts at equal intervals. A magnet block is fixed in a control head. The compound pickproof plug is simple in structure, convenient to operate, easy to mount and free of limitation of the thickness of the door frame edge.
