An arc plate 58 is fixedly connected to the outer wall of one side of the sliding plate 54. The filter plug 57 is clamped and fixed by setting the arc plate 58, and the filter plug 57 is separated and disassembled. The arc plate 58 is clamped on the outer wall of one side of the filter plug 57.

A through hole 3 is provided on the inner wall of one side of the fixed disk 2, and the through hole 3 passes through the inner wall of the side of the positioning cylinder 51.

[0026] Reference Figure 3-Figure 4 The auxiliary mechanism 6 includes an adjusting disk 61, which is hinged on the outer wall of one side of the positioning cylinder 51.
