[0023] It should be noted that, by providing the elastic member 1, the fixed position of the hydraulic hose is adjustable relative to the hydraulic support so as to more flexibly adapt to the lifting and lowering of the hydraulic support. When the hydraulic support is lifted, the elastic member 1 is stretched under the tension of the hydraulic support, and the hydraulic hose is unfolded at the same time; when the hydraulic support is lowered, the tension of the hydraulic support on the elastic member 1 is reduced, and the elastic member 1 contracts under the elastic restoring force, and the hydraulic hose bends and hangs under the elastic member 1, thereby preventing the hydraulic hose from dragging on the ground.

[0024] Specifically, the elastic member 1 is a spring.

[0025] In the hose fixing device of the present embodiment, the fixing assembly 3 includes a fixing rod 4, a fixing pin 5 and a fixing plate 6. The fixing rod 4 is connected to the elastic member 1. The fixing plate 6 is an arc-shaped structure. The two ends of the arc-shaped structure are respectively connected to the two fixing pins 5. The two fixing pins 5 are provided with through holes for the fixing rod 4 to pass through. The fixing rod 4 passes through the through holes on the two fixing pins 5 in turn, and a space for the hydraulic hose to pass through is formed between the fixing rod 4 and the fixing plate 6.
