[0019] By adopting the above technical solution and setting the clamping channel, the middle arc plate can be limited to prevent the middle arc plate from falling off from between the inner arc plate and the outer arc plate.

[0020] In a preferred example, the utility model can be further configured as follows: a plurality of inner arc-shaped plates are arranged in multiple rows at equal intervals and in a ring shape.
