A gear set with each gear driven by power and only provided with half teeth and a catching groove or two combined gear sets combined together in other connecting modes continuously and circularly move forwards, and the whole device is driven to move forwards to be used for four-footed animals which are ridden, transported and the like. The length of the forward teeth at the tail of the catching groove is equal to the forward movement distance of one combined gear set in one movement period, the teeth facilitate forward movement of the other gear set depending on the teeth, each leg is connected through fixing points, a certain distance away from a central point, on two gears (one positive gear and one negative gear) with the vertical line of the upper and lower central points facing each other, and the fixing point of the main gear is connected with the main leg. The middle of each leg is provided with a groove with the length not smaller than twice the length from a fixed point to a center point, the groove is connected with a fixed fulcrum which changes the position of the leg along with the groove along with the movement of a gear and the leg, the lower portion of the main leg is connected with an auxiliary leg capable of stretching up and down, and the other end of a connecting rod on the auxiliary leg is connected with a fixed point on an auxiliary gear. The two times of the distance between the fixed point and the central point meets the telescopic requirement of the auxiliary leg.

    由动力带动的每个齿轮只有半边齿牙的齿轮组和扣槽或其它的连接方式合在一起的两组组合齿轮组不停地循环向前移动,带动其整体向前移动可用于骑乘、运输等的四足动物,扣槽尾向前齿牙长度为一个组合齿轮组一个运动周期向前移动的距离,齿牙便于另一个齿轮组依托其向前移动,每条腿由上下中心点垂线正对的两个齿轮(一正一负)上距中心点一定距离的固定点连接,主齿轮固定点连着主腿,腿中间有一条长度不低于固定点到中心点二倍的沟槽,沟槽连接着一个顺着沟槽随着齿轮和腿运动改变其在腿部位置的固定支点,主腿下部连接着一个能上下伸缩的附腿,附腿上连杆另一端连着附齿轮上的固定点,固定点到其中心点距离的2倍满足附腿伸缩的需要。
