The invention provides a plastic link convenient for installation and disassembly, and relates to the field of plastic links. The plastic link convenient for installation and disassembly comprises a link body; one end of the link body is movably connected with one end of a buckling plate through a rotating shaft; one end, far from the rotating shaft, of the buckling plate is fixedly connected with a buckling block; one end, far from the rotating shaft, of the link body is fixedly connected with a connecting block matched with the buckling block; the bottom of the buckling block is fixedly connected with a fixed block; a clamping groove is formed in one side, far from the buckling block, of the fixed block; a groove is formed in the top of the connecting block; and the bottom of the groove is fixedly connected with a clamping block matched with the clamping groove. The plastic link convenient for installation and disassembly only needs to take out a damaged link to replace a new link, so that a plastic chain can be continuously used after replacement; and the plastic link convenient for installation and disassembly is simple and fast in disassembly and installation operations, and prevents the resource waste.
