Splicing magnetic self-adsorption type fast-assembly wall component

A magnetic self-adsorption type fast-assembly wall component capable of being spliced comprises an extrusion wood-plastic base body and further comprises a strong magnetic insert, the strong magnetic insert is embedded into the extrusion wood-plastic base body through a hot melting implanting technology, and the two sides of the extrusion wood-plastic base body in the thickness direction are provided with a corner overlapping splicing end and a stepped overlapping splicing end respectively. A long arm is arranged on the opposite side of the corner overlapping splicing end, a tenon end is arranged on the long arm, a concave tenon end is arranged on the close part of the stepped overlapping splicing end, the long arm is an arm which is formed by a preset distance from the base body and extends outwards, the tenon end is a convex clamping block, the concave tenon end is a concave clamping groove, and the convex clamping block and the concave tenon end are mutually matched. The clamping block and the clamping gro
