A end cover 9 is fixedly connected to the right surface of the melting pipe 5, and a filter screen 10 is fixedly connected to the left surface of the end cover 9.

[0025] A detachable fixing mechanism, which includes a connecting seat 11, a connecting rod 12, a fixing seat 13, a clamping block 14, a spring 15, a fixing frame 16, a slider 17 and a screw rod 18. The outer surface of the melting pipe 5 is fixedly connected to the fixing seat 13, and the outer surface of the end cover 9 is fixedly connected to the connecting seat 11.
