[0022] The transmission chain 30, the transmission sprocket 20, the drive motor 40 and the chain plate 50 adopt an annular chain plate conveyor belt, which can convey the gears in an annular manner. The connection method is an existing mature technical means, and the diameter-adjustable support 60 can limit the position of multiple superimposed gears, which can improve the stability of the gears during transportation.

[0023] Specifically, the diameter-adjustable pillar 60 includes a hollow column 61, the upper and lower inner walls of the hollow column 61 are rotatably connected with a screw 62, the screw 62 is threadedly connected with a pair of lifting round seats 63, the outer wall of each lifting round seat 63 is movably connected with a plurality of movable connecting rods 64, the bottom end of each movable connecting rod 64 is movably connected with a horizontal sliding rod 65, each horizontal sliding rod 65 extends to the outside of the hollow column 61, and each pair of horizontal sliding rods 65 is integrally connected with a vertical rod 66, which is located on the side of the horizontal sliding rod 65 away from the hollow column 61.

[0024] In this embodiment, by driving the screw rod 62 to rotate forward, the lifting round seat 63 can move downward, and the movable connecting rod 64 swings downward, and the horizontal slide rod 65 moves outward, so that the outer diameter can be increased. Similarly, the screw rod 62 is reversed to reduce the outer diameter, which can be applicable to gears of various sizes of inner diameters.

[0025] Specifically, a stud 80 is integrally connected to the middle of the bottom end of the hollow column 61 , and the stud 80 is threadedly fixedly connected to the top surface of the chain plate 50 .
