In order to ensure that when each supporting rod is vertically arranged, the free end of each supporting rod corresponds to a Y-axis coordinate YiLarger than the free ends of the other support rods andfor a Y-axis coordinate corresponding to the second end of a vertical plate, as shown in fig. 2, the extension lines of the support rods 53 intersect with the same point on the first horizontal plate 51, and for a circle with the same point as the center of the circle, the distance from the free end of each support rod 53 to the same point is equal to the radius of the circle. Because the second electric telescopic rod and the first transverse plate have certain lengths, the area capable of detecting pressure bearing of the invention cannot be a circular area taking the O point of the coordinate system as the center of a circle, but is an annular detection area taking the O point of the coordinate system as the center of a circle. Specifically, for the coordinate positioning device, determining that the second electric telescopic rod is completely contracted in an initial state, when the nth support rod in the direction from the second end to the first end of the first vertical plate is vertically arranged, the distance between the coordinate system O point and the nth support rod is taken as the circle center, the determined distance is taken as the radius to make a circle, and the circle is taken as the inner ring of the boundary line of the annular positioning area; and determining that the second electric telescopic rod is stretched to the longest length, and when the 1 st supporting rod is vertically arranged, taking the point O of the coordinate system as the center of a circle and the determined distance as the radius to make a circle, and taking the circle as the outer ring boundary line of the annular positioning area. In addition, for the engineering plate, the engineering plate is arranged in parallel to the X-Z plane, the central axis of the engineering plate is vertically intersected with the X axis, one side of the engineering plate is tangent to the inner ring boundary line of the annular detection area, and the tangent point is the intersection point of the X axis and the inner ring boundary line on the X-Z plane, so that the coordinate system conversion between the coordinate on the engineering plate and the device can be facilitated. It should be noted that: the support rod can be a linear support rod. The detachable contact external member is sleeved on the stand-by supporting rod, and the contact area between the stand-by supporting rod and the engineering plate is adjusted through the contact external member sleeved with different areas, so that the pressure bearing condition of the engineering plate under different force application areas is detected. The coordinate positioning device is adopted when the engineering plate is subjected to pressure bearing detection, so that the coordinate determination precision of points to be detected on the engineering plate can be improved.
