Four arc-shaped grooves 31 are distributed in a staggered manner in a rectangular shape on the inner wall of the frame 3. Among them, two arc-shaped grooves 31 horizontally aligned are the first group, and two arc-shaped grooves 31 vertically aligned are the second group. The horizontal height of the first group of arc-shaped grooves 31 is lower than that of the second group of arc-shaped grooves 31.
