So set up and can be when second actuating mechanism 700 and third actuating mechanism 800 rotate around the location axle that corresponds respectively, turned angle is great, even because assembly error, the reason such as machining error leads to the extending direction of friction band and the contained angle between the direction of arranging of a plurality of conveying rollers great, also can be through rotating second actuating mechanism 700 or third actuating mechanism 800, make the extending direction of second friction band 701 unanimous with the direction of arranging of a plurality of second conveying rollers 501 of second conveying mechanism 500, make the extending direction of third friction band 801 unanimous with the direction of arranging of a plurality of third conveying rollers 601 of third conveying mechanism 600, thereby ensure that roller conveyor 010 reliably works.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
