end. The technical field to which the invention described in the claims belongs.;The present invention relates to a cleaning broom for adjusting the angle of attachment of the bag, more specifically to the adjustment angle of the bag to be made within 90 degrees.;I. The technical problem the invention is trying to solve.;Conventionally, the cleaning broom for adjusting the angle of the bag is formed to protrude a semi-circular fixed shaft on the upper side of the body and to form a notch groove so as to be fitted around the fixed shaft on one end of the bag and hinged using a bolt and nut to adjust the angle. The range was formed to 180 degrees to maintain the adjusted angle only by the tightening force of the bolt and nut, there was an inconvenience that the cleaning is delayed for the adjustment of the angle by changing the angle arbitrarily during use.;All. The gist of the solution of the invention.;A fixed shaft having an elliptic curved surface at the top of the body is projected to a predetermined height, but the height of one side of the curved surface is formed to be higher than the depth of the notch groove so that the rotation of the bag is made within 90 degrees.;la.
