[0023] During specific use, the telescopic cylinder 5 is slidably connected to the support frame 6. When telescoping, it utilizes the first rotating shaft 4 connected at the top and the second rotating shaft 7 connected at the other side of the support frame 6. At the same time, the telescopic cylinder 5 slides on the surface of the support frame 6, so that the conveyor 1 is lifted on the top side of the support frame 6 to adjust the height.

[0024] Preferably, the support frame 6 , the third rotating shaft 9 and the rotating rod 10 form a rotating connection structure, and the bottom surface of the support frame 6 is connected to a protrusion and has a thread groove that matches the shape and size of the screw rod 14 .

Lifted upward sideways, when the telescopic cylinder 5 is extended, the first rotating shaft 4 connected at the top allows the telescopic cylinder 5 to be easily extended. At the same time, the support rod 8 connected at the bottom of the other side rotates together under the action of the second rotating shaft 7, so that the telescopic cylinder 5 can drive one side of the conveyor 1 to rise to an appropriate height to transport the goods. When transporting goods, the protective cover 18 installed on the top of the connecting plate 17 uses the four limit blocks 16 set on the chain plate 15 embedded on the surface of the transmission chain 2 to engage the connecting plate 17, so that the protective cover 18 limits the position of the goods transported on the surface of the transmission chain 2, avoiding the goods from falling from the side of the transmission chain 2 to the ground during transportation and affecting the transmission speed, and also avoiding pollution caused by the goods falling to the ground. This is a feature of the chain plate conveying mechanism of a hoist.
