The present invention is an improved invention of registered utility model 197664 of the applicant, and, in particular, to clamps for a pressure rice cooker, which prevents damage due to impacts by improving the structure of an operating unit of the clamps contacting a cam of a handle. The present invention relates to clamps (10, 20) for a pressure rice cooker, which are installed on each link on both sides (11, 21) connected by a tension spring (S), operated to left and right by a cam (31) of a handle (30) and opening/closing a lid (1) and a pot (2). Holes (12, 22) are respectively formed in the links (11, 21) of the clamps (10, 20), and operating rods (13, 23) are inserted into the holes (12, 22) and welded to fix. Rollers (14, 24) are respectively installed on the outer periphery of the operating rods (13, 23) to be rotatable, and the rollers (14, 24) rotate in the opening/closing operation of the clamps (10, 20) in the state that the rollers (14, 24) contact with the outer periphery of the cam (31). The cam (31) has a pair of a unlocking groove (32) and a locking groove (33) controlling the rollers (14, 24). |
