When it is necessary to clean the suspended matter on the filter screen 2 51, the fixed rod 2 55 can be driven to move upward by pulling the handle 3 56 upward. The fixed rod 2 55 drives the connecting plate 3 57 to move upward and compress the spring 58 through the action of the fixed connection, thereby driving the block 59 to move upward and release the restraint on the connecting plate 2 52. The filter screen 2 51 can be pulled out by pulling the handle 2 53 outward. After the suspended matter is cleaned, the filter screen 2 51 is inserted back into its original position and the handle 3 56 is released. The connecting plate 3 57 is driven downward by the elastic action of the spring 58, thereby driving the block 59 to move downward and start fixing the connecting plate 2 52, so as to achieve the effect of easy disassembly.
