Wherein, in order to facilitate the rotation of the driving shaft 3 and ensure the stability of the radial pressure of the shaft 3, the driving mechanism comprises a driven pulley 41 rotatably mounted on the moving seat 2, the driven pulley 41 is coaxially arranged with the shaft 3 and fixedly connected with the left end of the shaft 3, the driven pulley 41 is linked with a driving pulley 42 through a belt, the driving pulley 42 is linked with the output shaft of a driving motor 43 after passing through a reduction gearbox 44 fixedly connected with the moving seat 2, and the driving motor 43 is usually a three-phase motor. Since the driven pulley 41 and the driving pulley 42 are connected by the belt, the belt generates a radial force on one side of the driven pulley 41, and the driven pulley 41 is rotatably mounted on the movable seat 2, so that the rotating shaft 3 is prevented from being influenced by the radial force, and the stability of the rotating shaft 3 is ensured. As shown in fig. 2, in order to improve the compactness of the connection structure between the driven pulley 41 and the rotating shaft 3, the driven pulley 41 is sleeved with a fixed sleeve 21 and coaxially arranged, the right end of the fixed sleeve 21 is fixedly connected with the movable seat 2, and the driven pulley 41 is in rotating fit with the fixed sleeve 21 through a ball bearing; the connecting sleeve 31 is fixedly sleeved on the left end head of the rotating shaft 3, the connecting sleeve 31 is positioned between the fixing sleeve 21 and the rotating shaft 3, the left end of the connecting sleeve 31 is integrally connected with the inner ring part of the flange plate 32, and the outer ring part of the flange plate 32 is fixedly connected with the left side surface of the driven belt pulley 41, in particular to bolting.
