Abstract: A garlic crusher is composed of a upper pressing on which is disposed a pressing block, a lower pressing piece on which is disposed a garlic-pressing groove for accepting the pressing block, and a through-hole-matrix metal sheet. Using a pintle, the corresponding ends respectively of the upper and the lower pressing piece are connected to be a hinge joint. The garlic-pressing groove is disposed at one end of the lower pressing piece near the pintle, and formed by the downward through-aperture on the lower pressing piece and a through-hole-matrix metal sheet, which is inserted into the lower pressing piece through an inserting slot to take its position just above the widow disposed on the lower pressing piece. The garlic crusher is quite convenient in installation and in operation.
