The rotating push block 31 is designed to prevent friction energy consumption between the rotating push rod 30 and the rotating shaft 5 by rotating the rotating push block 31, and the rotating push block 31 is rotatably mounted at two ends of the rotating shaft 5 to prevent friction energy consumption between the rotating push rod 30 and the rotating shaft 5 through rotating fit, because the push rod 30 only moves transversely and the rotating shaft 5 rotates while moving.
According to the design, gaps are formed between two ends of the first guide sliding block 35 and two end faces of the travelling wheel 4, and the first guide sliding groove 34 formed in the rotating shaft 5 does not penetrate through two ends of the rotating shaft 5, so that the travelling wheel 4 and the rotating shaft 5 can be prevented from being separated from the rotating shaft 5 and falling off in the sliding process of the rotating shaft 5.
