Preferably, a groove 210 for embedding the magnetic steel sheet 5 is formed in the outer side surface of each arc-shaped plate 21, the magnetic steel sheet 5 can slide up and down along the groove 210 in the vertical direction, a limiting plate 211 for limiting the sliding of the magnetic steel sheet 5 is arranged at the top of the groove 210, and in order to enable the sliding of the magnetic steel sheet 5 to be less as possible, when the magnetic steel sheet 5 is pre-installed, the magnetic steel sheet 5 located at the upper position is preferably directly abutted against the limiting plate 211, so that only the magnetic steel sheet 5 located at the lower position is required to be displaced during subsequent sliding.
