A clamping assembly 5 is arranged on the side of the movable frame 8 close to the rotor shaft 4, and a distance adjustment assembly 6 is arranged at the bottom of the movable frame 8.

[0040] The clamping assembly 5 includes a tapered sleeve 51, and the side of the tapered sleeve 51 away from the rotor shaft 4 is movably connected to the movable frame 8, one of the movable frames 8 is equipped with a motor 3 for driving the tapered sleeve 51 to rotate, one of the movable frames 8 is movably connected to the movable frame 8 using a bearing seat, and the other movable frame 8 is movably connected to the other movable frame 8 using a bearing sleeve, and two clamping plates 55 are symmetrically arranged on the side of the tapered sleeve 51 close to the rotor shaft 4, and at least three adjusting blocks 52 are arranged on the side of the clamping plate 55 close to the tapered sleeve 51, and a socket 53 is provided on the side of the adjusting block 52 close to the clamping plate 55, and an insert block 56 is installed on the side of the clamping plate 55 close to the insert hole 53, and the insert block 56 is plugged into the socket 53, and at least two positioning screws 54 are movably penetrated in the clamping plate 55, one end of the positioning screw 54 is fixedly connected to the tapered sleeve 51, and a nut sleeve 57 is installed on the positioning screw 54.
