[0020] As the first embodiment of the utility model: a transmission wheel 302 and a flywheel 309 are respectively inserted on the outside and left and right ends of a group of shaft rods 301, and the flywheel 309 inserted on the right side of a group of shaft rods 301 is connected through a chain 310. The design can make the chain 310 drive a group of transmission wheels 302 to rotate through the rotation of the motor 307. The rotating shaft of the motor 307 is inserted at the right end of one of the shaft rods 301. A support plate is provided at the bottom of the motor 307, and the left side of the support plate is fixed to the right side of the transmission component 3 by welding. The design is conducive to driving the shaft rod 301 to rotate through the motor 307.
