A burglarproof lamp includes a lamp head part with a lamp head shell, a center contact bolt, a center contact insulation fixing base, a center contact insulation fixing sheet, a location post and a connection part fixing base. The center contact bolt is connected to a conductive pole after passing through the center contact insulation fixing base, the lamp head shell and the center contact insulation fixing sheet. The connection part fixing base has a boss and a containing cavity where a spring and a center conductive shaft are located. A conductive fixing ring is connected to the lamp head shell for limiting the position of the connection part fixing base via the boss. The center contact insulation fixing sheet has a location hole, into which the location post can be inserted when it is driven to the position corresponding to the location hole by the connection part fixing base.
