The invention discloses a corner connector dismounting and mounting joint structural component matched with a special-shaped profile. The corner connector dismounting and mounting joint structural component matched with the special-shaped profile comprises a joint structural body. The joint structural body is formed by connecting an exposed appearance decoration surface and a special-shaped profile assembly covering surface in a surrounding mode. The special-shaped profile assembly covering surface is provided with multidirectional angle connectors, an electric wire passing hole and electric wire turning grooves, wherein the multidirectional angle connectors can be inserted into the special-shaped profile provided with hole structures or a special-shaped pipe provided with hole structures, the multidirectional angle connectors are provided with expansion inverted buckle anti-disengaging clamping heads which are in close fit with holes, and thus the multidirectional angle connectors are not prone to looseness; and the multidirectional angle connectors are further provided with expansion fixing and clamping grooves, and the multidirectional angle connectors and the special-shaped profile or the special-shaped pipe can be further reinforced and positioned through fasteners. According to the corner connector dismounting and mounting joint structural component matched with the special-shaped profile, long strip-shaped materials with holes can be connected easily, operation is convenient and easy, framework models of various complex structures can be established rapidly, firmly and freely, dismounting and mounting are convenient, changes can be made freely, and the corner connector dismounting and mounting joint structural component is an ideal accessory in the furniture making industry, the decoration industry and the modeling industry.
