[0023] like Figure 1 and Figure 2As shown, a servo motor 2 is installed on the outer side of the connecting frame 1, and a connecting shaft 3 is installed on the output shaft of the servo motor 2 through a coupling, and a carrier frame 4 is fixedly installed on the end of the connecting shaft 3, and a fixing frame 5 is fixedly connected to the top of the carrier frame 4, and a bearing assembly 8 is slidably connected to the bottom of the fixing frame 5, and the bearing assembly 8 includes a carrier plate 81, a cross-shaped slider 82, a connecting mechanism 83, a conveying mechanism 84 and a positioning plate 85, and a cross-shaped slider 82 is fixedly installed on the top of the carrier plate 81, and the bottom of the cross-shaped slider 82 is fixedly connected to the top of the carrier plate 81, and the carrier plate 81 forms a sliding structure with the fixing frame 5 through the cross-shaped slider 82. By setting the carrier plate 81 and the fixing frame 5 in a sliding structure, the carrier plate 81 is more stable when moving back and forth along the inner surface of the fixing frame 5, and the top of the cross-shaped slider 82 is fixedly connected to the connecting mechanism 83, and the interior of the connecting mechanism 83 is movably connected to the side of the hand-rotating bidirectional screw rod 7, and at the same time, a conveying mechanism 84 is installed on the inner side of the carrier plate 81, and the conveying mechanism 84 includes a driving The drive motor 841, the drive shaft 842, the drive gear 843, the pulley 844 and the conveying belt 845 are provided, and the output shaft of the drive motor 841 is installed with the drive shaft 842 through a coupling, and the drive gear 843 is fixedly installed on the outer surface of the end of the drive shaft 842, the outer surface of the end of the drive shaft 842 is fixedly connected with the inside of the drive gear 843, and the outer surface of the drive shaft 842 is rotatably connected with the inside of the carrier plate 81, and the drive gear 843 forms a rotating structure with the carrier plate 81 through the drive shaft 842.
