A fixing column apparatus provided with an abrasion-resistant
gasket and an elastic ejection part and used for a PCB (
printed circuit board) is disclosed. The fixing column apparatus is used for being fixedly connected with a frame body (1) so as to fix the PCB (2) on the frame body (1); the fixing column apparatus comprises a fixing body (8), wherein the bottom of the fixing body is fixedly connected with the frame body (1); the fixing body (8) comprises a bottom shoulder part with a
shoulder surface (81) used for bearing the back surface of the PCB and a perpendicular column part (9) that is integrally formed and perpendicular to the
shoulder surface (81); the perpendicular column part (9) comprises a cylindrical root part (92) that is positioned at the bottom, integrally connected with the
shoulder surface (81) and used for jointing with a fixing hole in the PCB, a cylindrical top part (91) that is positioned at the
tail end of the top, and a middle connecting part that is cylindrical as a whole and positioned between the cylindrical root part (92) and the cylindrical top part (91).
