The cutting jig body 1 is installed on the left end surface of the water distribution frame 5. The outer wall of the cutting jig body 1 is integrally formed with six ribs 6 corresponding to the water distribution frame ribs 7 respectively. The right end of the cutting jig body 1 is connected to the water distribution frame 5 through a center positioning structure, a clamping structure and a rotation positioning structure.

[0021] The center positioning structure includes a center positioning column 10 and a positioning ring 9 on the water distribution frame 5 . The right end surface of the wire cutting fixture body 1 is integrally formed with a center positioning column 10 coaxial therewith, and the center positioning column 10 is inserted into the positioning ring 9 .

[0022] The right end of the center positioning column 10 is provided with an outer chamfer 13 for facilitating the insertion of the positioning ring 9 .

[0023] The clamping structure includes a clamping groove 12. An annular clamping groove 12 is opened on the outer wall of the wire cutting jig body 1, and the clamping groove 12 cooperates with the positioning ring 9 on the water distribution frame 5. The right end surface of the rib 6 protrudes and is located on the right side of the left bottom of the clamping groove 12, and the outer wall of the positioning ring 9 is slidably connected to the rib 6.

[0024] The width of the rib 6 gradually decreases from left to right.
