Abstract:
1. A scraper structure, comprising: a handle for a handgrip; and a tapered scraping section positioned at a front end of the handle, the scraping section tapering towards the front end of the handle, and an opposing end terminating in an L-shape; wherein the handle has a grip opposite the scraping section and a connection groove in the front end configured to assemble with a coupler at a rear end of the scraping section, wherein the tapered L-shaped scraping section further including an L-shaped jaw plate, a blade, a fastener and a fastening button, the L-shaped scraping section formed by a front end of the scraping section extending downward to form a substantially planar blade slot having an inner surface with a plurality of connection pins and a jaw groove connected to the blade slot on a bottom surface of the scraping section and angled with respect to the blade slot, the blade configured to fit into the blade slot and including a plurality of corresponding connection holes to the plurality of connection pins on the blade slot, such that the holes and the pins lock to each other for assembly, a round hole located at a rear end of the jaw groove, and extending to a top of the jaw groove, and associated with the round hole is a square groove on an inner side of the jaw groove, the scraping section also including a circular groove on a top surface of the scraping section, the jaw plate fitting within the jaw groove, wherein a front of the jaw plate includes a clamp jaw to match an orientation of the blade slot, the clamp jaw forming an angle with a main surface of the jaw plate that is greater than the angle formed between the blade slot and the jaw groove, so that the clamp jaw presses onto the blade inside the blade slot, and a rear end of the jaw plate includes a square hole, the fastener including a retaining ring, a square restriction block and a screw thread, wherein the screw thread passes through the square hole of the jaw plate and the round hole of the scraping section, the fastening button including a molded cap nut, wherein the fastening button is combined with the screw thread of the fastener by the cap nut on the top surface of the scraping section to restrict the jaw plate and the jaw groove assembly of the scraping section and to provide a tightening force to enable the clamp jaw in the front of the jaw plate to exert onto the blade.
