lower half shell, H-shaped blocks, rising prevention plates, an arc clamp,a cutter, a drive sleeve, a sleeve
pipe, a steering pull hook and a protection cover. A limit block is arranged at the inner side of the arc clamp, two clamp pins are arranged at the
tail end of thearc clamp, and a fixing point is arranged at the
tail end of each clamp pin. A cutter guide groove is formed in the middle of the
lower half shell, an arc clamp guide hole is formed in the middle-backportion of the
lower half shell, two guide fixing blocks are arranged at the
tail end of the lower half shell, two limit pits are formed in front of the guide fixing blocks respectively, and a limitopening is formed in the tail end of a cutter assembly.
