The handle has two side vertical rods, which fit respectively in the two ends of the lateral rod and provided with a plurality of position holes. When the handle is needed to be adjusted in its height, the pull rod is pushed to force the two ends to move inward to each other elastically in the two slide grooves of the lateral rod, and then the handle can be adjusted in its height by moved up or down, and then the pull rod is released to fit elastically in a new position hole in two side rods of the handle to keep immovable the handle at the newly adjusted height.
