Power transmission is achieved between the chain driving mechanism 3 and the chain driving mechanism 5 through a transmission chain 4, and the transmission chain 4 is tensioned by tensioning sprockets 6 arranged on the left and right sides of the front of the base 1 to ensure stable power transmission; a cable drum 2 is arranged above the chain driving mechanism 5, and stabilizing auxiliary wheel mechanisms 7 are arranged on the left and right sides of the chain driving mechanism 5, and the stabilizing auxiliary wheel mechanism 7 is rotatably connected to the cable drum 2.

[0026] The chain drive mechanism 3 includes an outer shell 31, an inner cavity 32 is arranged inside the outer shell 31, a partition 35 is arranged in the middle below the inner cavity 32, a driving wheel 33 is arranged inside the outer shell 31 just above the partition 35, and a transmission wheel 34 is arranged on the left and right sides of the partition 35, and the part of the transmission chain 4 located in the inner cavity 32 passes through the driving wheel 33 and the transmission wheel 34 respectively and moves inside the inner cavity 32 as the driving wheel 33 and the transmission wheel 34 rotate.

[0027] The driving wheel 33 and the transmission wheel 34 are connected to the outer shell 31 through bearings 36 , and gaskets 37 are arranged between the bearings 36 and the corresponding driving wheel 33 and transmission wheel 34 .
