Combined plastic gasket

The utility model discloses a combined type plastic gasket, which belongs to the technical field of plastic gaskets, and comprises two gasket bodies, a limiting ring and a plurality of groups of conductive positioning pieces, the two gasket bodies are annular and are symmetrically arranged, the end faces of the two gasket bodies are attached, the limiting ring is positioned on the inner sides of the two gasket bodies, and the conductive positioning pieces are arranged on the limiting ring. The two gasket bodies are respectively clamped by the limiting rings; according to the anti-static plastic gasket, the conductive positioning piece is connected with the two gasket bodies which are symmetrically arranged in the clamping mode, the limiting rings are located in the gasket bodies and clamp the two gasket bodies, the conductive positioning piece extends to the end portions of the gasket bodies to absorb static electricity on the surfaces of the gasket bodies and guide the static electricity out of the side face
