Abstract

The utility model provides a plaster trowel. A handle of the plaster trowel has a cylinder shape, a pylome passes through a circular face center, a groove is ring lathed on the handle front end surface, a front trowel hoop is coated on the handle front end, back end of the front trowel hoop is packed in the groove, the handle back end circular face shows flute shape, the back trowel hoop is coated on the handle back end, one end of a trowel rod inserts into the pylome of the handle center which is fixed by nut, a pattern is set in the nut inner end face, another end of the trowel rod bends downwards to block into the groove of the handle front end circular face, an end face is inserted into the center pylome of a connecting piece for down welding, the pylome on the connecting piece is taper, down part of the connecting piece is equipped with a trowel blade connected by rivet, the hole corresponding to the trowel blade and the connecting piece are also taper. The plaster trowel has advantages that the taper hole design of the connecting piece and the trowel blade makes the plaster trowel more firmly and smoothly after the rivet down, the trowel rod inserts into the connecting piece for down welding for making the connecting part filling full and seamless, the connecting more smoothly and firmly, the trowel handle front end groove design makes the front trowel hoop more steadily which increases working life, the nut pattern design makes the plaster trowel no easy falling off in use.
