The support seats 3, the arc-shaped slots 5 and the arc-shaped limit blocks 6 are all arranged in equal lengths. The main body 2 is placed at the upper ends of several support seats 3 between two adjacent support plates 1, so that the high-chromium bearing steel main body 2 is inserted into the arc-shaped grooves 5 on the several support seats 3, and the front and rear ends of the high-chromium bearing steel main body 2 are respectively in contact with the two rectangular protrusions 8 in the arc-shaped grooves 5, and the annular side wall of the high-chromium bearing steel main body 2 is in contact with the arc-shaped side walls of the two arc-shaped limit blocks 6, effectively dispersing the load and limiting the several high-chromium bearing steel main bodies 2, and preventing the high-chromium bearing steel main bodies 2 from accumulating and affecting the quenching effect.
