Referring to fig. 1, the notch 1021 is configured to extend from two sides of the outer edge of the tooth body 102 to a position near the center of the outer pot body 101. For example, the notch 1021 is disposed on the left and right sides of the handle body 102, and the depth of the notch 1021 along the center close to the outer pot body 101 (i.e. the depth of the notch along the horizontal direction of the outer pot body 101) may be the same as the length of the handle body 102 along the center away from the outer pot body 101, or may be smaller than the length of the handle body 102 along the center away from the pot body (i.e. the length along the horizontal direction of the outer pot body 101), and when the depth of the notch 1021 is smaller than the length of the handle body 102, the notch 1021 and the corner of the outer pot body 101 are in arc transition arrangement, and the notch 1021 and the corner of the handle body 102 are in arc transition arrangement.
