[0021] Furthermore, the left end of the water outlet pipe 3 is provided with a thread on the outer wall that matches the screw cover 4, and the locking block 8 forms a rotating structure with the outer frame 10 through the connecting rod 7, the blocking block 6, the screw cover 4, so that the outer frame 10 and its related components are limited by the locking block 8 locking in the locking groove 9, and the filter cloth 12 and its related components are conveniently moved through the connecting rod 7 and the screw cover 4.
[0022] The filter cloth 12 is inserted between the outer frames 10 , and a plurality of first bolts 11 are evenly screwed on the outer frames 10 . The other ends of the first bolts 11 are screwed with nuts on the outside of the right outer frame 10 .
[0023] Furthermore, the outer frame 10 forms a spiral locking structure through the first bolt 11 , the nut and the filter cloth 12 , so that the two sets of outer frames 10 are bolted together through the first bolt 11 , thereby facilitating the replacement of the filter cloth 12 .
[0024] A second bolt 13 is screwed on the water outlet pipe 3 above the outer frame 10 , and the other end of the second bolt 13 is screwed on the outer frame 10 . A glass plate 14 is embedded in the outer frame 10 on the front side of the water outlet pipe 3 .
