This kind of multi-functional novel draw-bar box climbs subassembly 4 through setting up the shock attenuation, and is simple high-efficient, can realize the walking freely of complicated topography like stair, step etc. and it is laborsaving to save trouble. The height of the pull rod 2 can be adjusted while the pull rod can freely walk on a plane. By providing the second spring 45, the roller 47 is damped. By providing the first spring 44 and the cylinder 43, the support frame 41 is elastically supported.

Compare with current 2 casees of pull rod, the novel 2 casees of pull rod of embodiment are convenient for people's multiple user demand more, have added support frame 41, elasticity gyro wheel 47, elasticity draw-in groove and rotary switch's structural design for 2 casees of pull rod not only use easily freely on the level land, have saved not few troubles moreover when stair use. As shown in fig. 7, the supporting bracket 41 is connected to the case 1 by a shaft, and a cylinder 43 surrounding the second spring 45 is connected therebetween so that the supporting bracket 41 can be opened slowly around the shaft. The rollers 47 at the bottom enable the support frame 41 to slide with the cabinet 1 in a rotated open state. The front surface of the support frame 41 is also treated so that the resilient roller 47 is sufficiently exposed in the closed state. The resilient rollers 47 are arranged in rows on the tailgate 42, and the rear second spring 45 makes the rollers 47 sufficiently resilient.

The shock-absorbing crawling assembly 4 further comprises a pressing ejector which is arranged between the supporting frame 41 and the rear baffle 42 and arranged on the rear baffle 42, an iron sheet is arranged on the supporting frame 41 and corresponds to the pressing ejector. The ejector and the cylinder 43 are respectively provided at both ends of the tailgate 42. The ejector is caught or ejected by pressing the support bracket 41 as shown in fig. 6.
