The smaller the distance is, the less the degree of allowable deviation of the conveyor belt 20 is; but not limited to this. It is also possible that there is no two sliding grooves 511 or no adjustment base 51, but the sensor 52 is directly fixedly disposed. In addition, there can be only one sensing component 50, or only two sensing components 50 can be respectively disposed on both sides of the conveyor belt 20, and each sensing component 50 has only one sensor 52, which can also achieve sensing transportation.
