The quick-locking mechanisms are connected to the free ends of the scissor-type telescopic assemblies. The lifting supports are provided with lifting mechanisms, and the lifting mechanisms are provided with power mechanisms. The output end of the power mechanisms is connected to the rotating rollers through a transmission chain.

[0011] Preferably, the lifting support includes an upper support that is rotatably connected to the rotating roller, a strip-shaped opening is provided on the upper support, a lower support is slidably connected to the lower end of the upper support, and a fastener is threadedly connected to the upper support.

[0012] Preferably, the lifting mechanism includes a guide rod and a lead screw connected to the power mechanism. The lead screw is rotatably connected to the power mechanism, threadedly connected to the upper support, and slidably connected to the upper support.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model opens the quick-lock mechanism, and the scissor-type telescopic component is in a free-moving state. The distance between the rollers is adjusted according to the required length, thereby adjusting the length of the conveying device. Then, the quick-lock mechanism is locked, thereby fixing the roller distance and the length of the conveying device. Then, the upper and lower positions of the power mechanism are adjusted by the screw to tension the transmission chain and ensure transmission efficiency. At the same time, by changing the relative positions of the upper and lower supports and using fasteners, the height of the conveying device is changed, making the conveying device more versatile and meeting the usage requirements.

[0023] Open the quick-lock mechanism 6, and the scissor-type telescopic assembly 5 is in a free-moving state. Adjust the distance between the rollers 4 according to the required length to adjust the length of the conveying device. Then lock the quick-lock mechanism 6 to fix the distance between the rollers 4 and the length of the conveying device. Then adjust the up and down position of the power mechanism 10 through the lead screw 12 to tension the transmission chain 9 and ensure transmission efficiency. At the same time, change the relative position of the upper support 1 and the lower support 2 and use the fasteners 8 to change the height of the conveying device, so that the conveying device has high applicability and meets the usage requirements.
