Abstract

The invention discloses a tightening nut of a chasing tool slot grinder. The tightening nut comprises a metal seat composed of a first metal layer, a second metal layer and a third metal layer in corresponding connection. The first metal layer, the second metal layer and the third layer which are concentric are a large cylinder, a medium cylinder and a small cylinder respectively. Six notches are dug inwards in the circumferential edge of the first metal layer and evenly distributed in the circumferential edge, and a transverse connection line of middles of the left-end notch and the right-end notch is superposed with a transverse diameter line of the first metal layer. The lower side of the second metal layer is connected with the upper side of the first metal layer. A circular groove is dug inwards in the circular upper side of the second metal layer, and the inner and outer groove walls of the circular groove are concentric with the second metal layer. The lower side of the third metal layer is connected with the upper side of the second metal layer. A threaded hole which is a through hole is downwards drilled in the circle center of the circular upper side of the metal layer, and the circumferential edges of the circular upper side, the lower side and the middle of the metal base are all chamfered into 45 degrees.
