In addition, the positioning plate 30 may have other elongated shapes, such as an elongated cylinder, a trapezoidal elongated plate or column, an irregular elongated plate or column, etc.

Further, the number of the positioning pieces 30 is at least one. In the example shown in fig. 1, the number of splines 30 is two. In practical use, the number of the positioning pieces 30 can be one, two, three, four, five, etc. according to the length of the detected floor and the length of the inner edge of the first edge 22 and the second edge 24 of the right-angle outer frame 20. Therefore, the floor squareness measuring instrument 10 can be directly placed on the floor for detection, and the operation is simple and convenient.

Furthermore, the distance between the first end 32 and the corner of the bezel 20 can be equal to the distance between the second end 34 and the corner of the bezel 20, which is symmetrical in appearance, and can assist in visually roughly determining the right angle.

Further, the first side 22 and the second side 24 of the right-angle frame 20 are configured to be mounted on two adjacent sides of the floor 40 to detect the right angle of the floor 40. In addition, the distance between the first end 32 and the corner of the right-angle outer frame 20 is greater than half of the length of the inner edge of the first edge 22, so that the floor can be less prone to tipping when the floor squareness measuring instrument 10 measures the floor.
