摘要： A handle of a trowel, comprising a penetrating hole disposed longitudinally within, with one end rim thereof extending to form an arcuate bearing piece permitting a narrow rod of a blade to insert in the penetrating hole and to press against onto a concaved arc-plane on the front rim of the bearing piece, is characterized that the circumferential side of the penetrating hole of the handle is disposed longitudinally with a plurality of ribs to enable the inserted narrow rod at the distal end of the blade to have preferred tightness; a disposed sealing cover and the bearing piece have corresponding shapes, both interlock correspondingly by means of a concave and a convex fastening members to sheath and firmly seal the narrow rod of the blade.
