[0032] One end of the sector thread detection block 101 is fixedly connected with a limit straight block 102 and a cylindrical block 103 in sequence. The limit straight block 102 is slidably connected to the inner side of the straight guide groove 202, and the cylindrical block 103 is slidably connected to the inner side of the extended arc groove 206;

[0033] The outer diameter of the cylindrical block 103 is greater than the width of the limit straight block 102. The outer diameter of the cylindrical block 103 matches the difference between the inner and outer diameters of the extended arc groove 206, and the width of the limit straight block 102 matches the inner wall width of the limit straight block 102;
