Circular grater for cutting plastic
摘要:
The present invention is a circular grater for use in combination with a power-driven hand tool. The power driven hand tool includes a motor within a housing and a shaft mechanically driven thereby. The hand tool also includes a circular mounting member which is mechanically coupled to the shaft so that it rotates thereon and a first flat disc-shaped member which is mechanically coupled to the circular mounting member. The circular grater includes a second flat disc-shaped member which has a first surface adapted for grating a plastic material and a second surface, a plurality of coupling members each of which has a disc-shaped head portion which is mechanically coupled to the second surface of the second flat disc-shaped member, a cylinder-shaped portion of a particular diameter and a screw portion of a diameter smaller than the particular diameter which is adapted to be inserted into a hole in the first flat disc-shaped member, and a plurality locking wing nuts for fastening the coupling members.
