[0021] The flipping mechanism 2 includes a DC motor 26, which is fixedly installed on one side of one of the vertical shells 4. A first support 25 for use with the DC motor 26 is fixedly installed on one side of one of the vertical shells 4. The DC motor 26 is fixedly installed on the upper surface of the first support 25, which facilitates the stable installation of the DC motor 26. A central shaft 23 is fixedly connected to the output end of the DC motor 26. The output end of the DC motor 26 drives the central shaft 23 to rotate. The end of the central shaft 23 facing away from the output end of the DC motor 26 passes through one of the vertical shells 4 and is rotatably connected to the inner cavity of the other vertical shell 4 to ensure the stability of the rotation of the central shaft 23. A protective shell 24 for use with the central shaft 23 is fixedly connected to the opposite side of the vertical shells 4. The central shaft 23 is located inside the protective shell 24, which protects the central shaft 23 and prevents the operator from accidentally contacting the rotating shaft.
