When the device is used, as shown in fig. 3, two probes are put down at the right-angle corner of the device indoors, the positioning telescopic rods are extended to the limit, the floor 1 plane is taken as a right-angle coordinate plane, the probes are taken as the original points, when two fixed telescopic rods of a certain probe are extended to the limit, the transverse and longitudinal coordinates of the probe are established, and when two pairs of same positioning telescopic rods of the two probes are extended to the limit, the two probes are vertically opposite at the upper side and the lower side of the floor 1, so that the value displayed by the device body can be quickly obtained, the thickness of the floor 1 can be quickly and accurately measured, even if slight errors exist, the real minimum value (the thickness of the floor 1) can be obtained only by slightly adjusting the moving range of one probe, and the device is particularly suitable for the existing commercial houses. Certainly, can select whether to extend four or relative or adjacent two location telescopic links simultaneously as required when using, and it is better to lean on the wall angle department according to specific indoor environment, but should not directly be in the wall angle department, because, usually there is an inclination wall angle department, and the floor 1 that surveys out is not the true thickness of nearest, and the space is too narrow and small, and the instrument of being inconvenient for places, consequently, it is suitable to detect with the floor 1 that is close to the corner department, even if be convenient for set up the instrument, can not need longer location telescopic link again. For the special-shaped house types with different house types of the upper floor and the lower floor under the extreme condition, the length of the corresponding positioning telescopic rod is measured to determine the special-shaped house types, so that more accurate numerical values can be obtained, and compared with the prior art that the blind measurement of the positions of two operators on one floor and one floor is more rapid and accurate.
