Further, since the inner shaft sleeve 23 and the middle bearing 22 are fixed to freely roll along the inside of the outer sprocket 21, if the outer sprocket 21 rotates around the center of a circle, the output shaft 24 mounted on the inner shaft sleeve 23 does not have power transmission. Therefore, the center point of the output shaft 24 after installation, i.e. the center point of the large key slot hole 232 on the inner shaft sleeve 23, should keep a certain distance a from the center point of the outer chain wheel 21, and the center point of the transmission shaft 36 of each input mechanism also keeps the same distance a from the center point of the small chain wheel 31, and the connection lines between the centers of the chain wheels and the center of the output shaft 24 or the center of the input shaft 36 are ensured to be parallel to each other during installation, so that the inner shaft sleeve 23 and the middle bearing 22 will rotate at a constant speed under the rotation and extrusion of the outer chain wheel 21, and the output shaft 24 can also obtain constant.
