For the measurement of the arc corner of the building, the telescopic rods 2 can be directly stretched to the longest, and then the measuring ruler body 1 is pushed to the arc corner of the building. As the measuring ruler body 1 approaches the building corner, the top block structures 3 on the telescopic rods 2 at different positions will be pressed at different positions of the arc corner of the building. At this time, the arranged telescopic rods 2 will be contracted to a corresponding degree, and then the measuring ruler body 1 will be separated from the building corner.

[0027] Furthermore, the openings of the first sleeve 201, the second sleeve 202 and the third sleeve 203 are designed in a T-shape, and the second sleeve 202, the third sleeve 203 and the insertion rod 204 are in a T-shape facing one end of the first sleeve 201.

[0028] Furthermore, rubber rings 205 are arranged in the openings of the first sleeve 201, the second sleeve 202 and the third sleeve 203. The rubber rings 205 increase the friction force. When the second sleeve 202, the third sleeve 203 and the insertion rod 204 are extended or retracted, they can be fixed by the friction force.

[0029] In a specific embodiment, the top block structure 3 includes a top plate 301, which is arranged at the free end of the telescopic rod 2, and a circular second through hole 302 is opened in the center of the top, a top rod 304 is inserted into the second through hole 302, and a conical end 305 is arranged at the bottom end of the top rod 304.

[0031] Furthermore, a round block 306 is arranged at the top of the push rod 304, and the diameter of the round block 306 is larger than the diameter of the second through hole 302. The round block 306 can prevent the push rod 304 from escaping from the second through hole 302 from the top.

[0032] Furthermore, a rubber sleeve 303 is arranged inside the second through hole 302, and the rubber sleeve 303 serves to increase friction.

As the measuring ruler body 1 approaches the building corner, the top block structures 3 on the telescopic rods 2 at different positions will be pressed against different positions of the arc corner of the building. At this time, the arranged telescopic rods 2 will shrink to a corresponding degree, and then the measuring ruler body 1 will be separated from the building corner. At this time, the top block structures 3 on the telescopic rods 2 at different positions will form a contour similar to the arc of the building, so as to realize the demoulding of the building corner. Then, the personnel can draw the arc shape of the building by forming the contour of the top block structure 3 and cooperating with manual improvement. Then, the personnel can measure the arc shape of the building drawn out, so as to obtain the data of the arc corner of the building, and can also cut some building materials according to the drawn building shape to match it with the building corner. Therefore, the utility model itself can effectively demould and measure the corners of the building arc, obtain the parameters of the building corner, and facilitate the corresponding cutting with the building materials, so as to effectively improve the performance of the device.

[0034] Secondly, when it is necessary to measure the height difference between two points on a plane, the top rod 304 on the top plate 301 at the corresponding two points on the plane can be pushed down until the bottom end of the tapered end 305 on the top rod 304 contacts the two points on the plane, and then the height difference at the bottom end of the tapered end 305 on the two groups of top rods 304 is measured, which is the height difference between the two points on the plane. This method can also measure whether the plane is horizontal, further improving the performance of the device.
