Figure 3 As shown, a plurality of through openings 105 are provided, and the spacing between adjacent through openings 105 is greater than the inner diameter of the injection port 108, so that the injection port 108 may not be connected to any through opening 105;

[0030] The outer wall of the fixed sleeve 101 and one end above the rotating sleeve 106 is fixedly connected with a connecting ring, and the inner wall of the fixed sleeve 101 located at the connecting ring is penetrated and connected with a fastening bolt 103.
