The adjustable support base 21, the adjustable support column 22, the mounting head 23 and the adjustable bracket 24 are arranged and connected in sequence from bottom to top, and the chute body 1 is supported by the adjustable bracket 24;

[0035] It should be noted that when the device is in use, multiple chute bodies 1 are supported by multiple support components 2, and the multiple chute bodies 1 are connected by a connecting component 3. The adjustable support base 21 is retractable and can be opened when in use, thereby ensuring the stability of the support component 2. The adjustable support column 22 is adjustable in length, so the height of the device can be adjusted as needed. The chute body 1 is supported by the adjustable bracket 24.
