ABSTRACT:
A container coupling tool including a tool body having a flange and positioning protrusions provided on top and bottom of the flange. The tool body is formed with a bore extending therethrough from the top surface of one of the protrusions to the bottom surface of the other. A rotary shaft is received in the bore and has at its top and bottom ends top and bottom cones. Also, handle is inserted in a hole formed in the tool body and is coupled to the rotary shaft. The tool body is formed with a stopper hole opening to the bottom of the flange and communicating with the bore. A stopper having a stopper pin is vertically movably inserted in the stopper hole. The rotary shaft is provided on its outer periphery with engaging projections adapted to oppose the stopper pin in the circumferential direction of the rotary shaft when the stopper pin is received on the bottom end of the stopper hole with the tool body used in an upside down position , thereby preventing the rotary shaft from rotating toward a position where one of the top and bottom cones disengages.
