The setting of balancing weight can ensure that first light beam source emission initial mode is vertical up all the time. The first reflection group and the second emission group are used for prolonging the beam path of the first beam source 24, so that the path of the first beam source 24 is prolonged, firstly, the size of the box body 1 can be reduced, if the size of the box body 1 is too large, when the guide groove 11 is matched with an elevator guide rail, if a deformation part of the guide rail exists, the box body 1 can not normally pass, and the detection precision is reduced by increasing the gap of the guide groove 11; secondly, by extending the beam path and disposing the light shielding plate 27 between the first reflecting component and the second reflecting component, only in the vertical state of the box body 1, or in a small range deviated from the vertical straight line, the light of the first beam source 24 can reach the first photosensor 21 through reflection, the first photosensor 21 has a circular sensing range with a small size, and when the deviation angle exceeds the range, the light cannot reach the position of the first photosensor 21 due to the influence of the light shielding plate 27.
