When the screening iron mesh 111 needs to be replaced or cleaned, the bolt 104 is unscrewed outward along the threaded hole 103 to disengage the bolt 104 from the limiting rod 105. Then, the limiting rod 105 is rotated around the rotating rod 108, thereby disengaging the limiting ring 106 from the limiting block 109. Then, the box door 102 is opened to remove the screening iron mesh 111 that was restricted by the limiting plate 110. The operation process is simple and convenient, greatly shortening the replacement time.
