Drainage pipe network dredging and cleaning equipment

The utility model belongs to the field of drainage pipe network dredging and cleaning, and particularly relates to drainage pipe network dredging and cleaning equipment which comprises a column body, a drill bit and a mounting plate fixedly mounted on one side of the drill bit. A cavity is formed in the mounting plate, and limiting rods are rotationally connected to the top and the bottom of one side of the inner surface of the cavity through bearings; the gear and the limiting rod are conveniently driven through the tooth frame, so that the direction of the limiting rod is changed, due to the fact that protrusions are arranged at the two ends of the limiting rod, after the direction of the limiting rod is changed, the protrusions can be clamped in the limiting grooves, at the moment, fixing is conducted through the screw, the mounting hole and the moved position of the tooth frame, and then mounting of the drill bit and the column body can be completed; and meanwhile, the screw rod is rotated to be separated
