The existing screw positioning mode is to position a single screw through a simple positioning iron sheet with two holes, firstly, after marking the positions of the two positioning holes through a marker pen, positioning another screw through another hole on the positioning iron sheet, marking, welding the screws, ensuring the perpendicularity and the distance of the screws, ensuring the relative independence of the whole screw positioning process, complicated field operation process, poor accuracy and low success rate, and for sensors with different specifications and models, manufacturing different positioning iron sheets again is needed, so that the waste of resources is caused.
