Direct insertion type pile head convenient for quick connection of cable

The utility model relates to a direct insertion type pile head convenient for quick connection of cables, which comprises a plurality of connecting columns connected through plastic parts, and each connecting column is provided with a connecting end and an insertion end; the inserting grooves are formed in the inserting ends, and a plurality of adjusting grooves are formed in the circumferential positions of the inserting grooves; a compression nut; the pressing nut is arranged on the wire in a sleeving mode, the end of the wire is inserted into the inserting groove, then the pressing nut is screwed into the outer wall of the inserting end, the gap of the adjusting groove is reduced due to the extrusion force of the pressing nut, the inserting groove is deformed, and the wire is pressed. The end part of the wire is directly inserted into the insertion groove, and the compression nut is screwed along the axial direction of the wire, so that the insertion groove is deformed, i.e., the gap of the adjustment groo
