[0054] Specifically, the connecting plate assembly 101 is composed of two connecting plates, namely an upper connecting plate 101-1 and a lower connecting plate 101-2; the upper end of the first flexible plate is clamped and fixed by the upper connecting plate 101-1 and the lower connecting plate 101-2 of the first group, and its lower end is clamped and fixed by the upper connecting plate 101-1 and the lower connecting plate 101-2 of the second group; the upper end of the second flexible plate is clamped and fixed by the upper connecting plate 101-1 and the lower connecting plate 101-2 of the second group, and its lower end is clamped and fixed by the upper connecting plate 101-1 and the lower connecting plate 101-2 of the third group, and so on.

[0062] It should be noted that the middle towing rope 201 is directly connected to the corresponding adjustable assist spring mechanism 304. The left towing rope 201 passes through the guiding paths of the two wheel frames 302 on the left in sequence and then is connected to the corresponding adjustable assist spring mechanism 304. The right towing rope 201 passes through the guiding paths of the two wheel frames 302 on the right in sequence and then is connected to the corresponding adjustable assist spring mechanism 304.

[0063] In the above embodiment, preferably, the adjustable assist spring mechanism 304 includes: a hollow screw 3041, a positioning nut 3042, a sleeve 3043, a spring 3044, a retaining plate 3045, and a towing rope adjusting mechanism 3046. The sleeve 3043 is arranged on the cylinder base 303. The two sides of the positioning nut 3042 are fixedly connected to the sleeve 3043. The spring 3044 is arranged inside the sleeve 3043. The hollow screw 3041 is threadedly connected to the positioning nut 3042 to compress and loosen the spring 3044 by rotating the hollow screw 3041. The towing rope adjusting mechanism 3046 is located at the lower end of the spring 3044. The retaining plate 3045 is arranged on the towing rope adjusting mechanism 3046 and is located between the spring 3044 and the towing rope adjusting mechanism 3046. The towing rope 201 passes through the hollow screw 3041, the positioning nut 3042, the sleeve 3043, and the spring 3044 in sequence and is then clamped by the towing rope adjusting mechanism 3046.

[0064] In the above embodiment, preferably, as Figure 5 and Figure 6 shown, the towing rope adjusting mechanism 3046 includes: a pressing head 3046-1, a plunger 3046-2, a ball 3046-3, a conical spring 3046-4, and a gland 3046-5. The pressing head 3046-1 is a conical sleeve structure with a smaller upper part and a larger lower part. The plunger 3046-2 is arranged inside the pressing head 3046-1. A number of balls 3046-3 (three in this embodiment) are arranged on the side wall of the plunger 3046-2. The plunger 3046-2 has a stepped surface which is arranged below the balls 3046-3. The conical spring 3046-4 is sleeved on the plunger 3046-2. The gland 3046-5 covers the lower end of the pressing head 3046-1.

[0065] During use, the plunger 3046-2 is pushed by the tapered spring 3046-4. There are three balls 3046-3 evenly distributed around the plunger 3046-2, and the three balls 3046-3 form a triangle. When the tapered spring 3046-4 pushes the plunger 3046-2 at the outlet of the indenter 3046-1, since the combined diameter of the three balls 3046-3 is larger than the outlet diameter of the indenter 3046-1, the plunger 3046-2 will be clamped and fixed; when the towing rope 201 passes through the inner hole of the plunger, it can be squeezed by the balls 3046-3. Due to the increased friction, the towing rope 201 is simultaneously pressed tightly to prevent loosening; when loosening is required, pressure can be applied to the head of the plunger 3046-2 to reverse-press the tapered spring 3046-4, and the balls 3046-3 will loosen, and the towing rope 201 will naturally loosen and unlock; the gland 3046-5 is used to prevent the tapered spring 3046-4 from falling off and is fixed.

[0066] In the above-mentioned embodiment, preferably, the wheel carrier 302 includes a pulley 3021 and a pulley post 3022; the pulley 3021 is arranged at the free end of the pulley post 3022; the towing rope 201 is wound around the pulley 3021 so that the towing rope 201 extends along a set path.
