[0002] Building materials refer to various materials used in construction projects to construct and decorate buildings. These materials are of various types and have different characteristics and uses. Wood boards, as a common material, are widely used in construction projects. The flatness of wood boards not only affects the appearance of the building, but is also directly related to the stability and service life of the structure. Therefore, flatness detection devices are often used for detection.

[0003] For example, the building material detection device with publication number CN216482773U can accurately detect the flatness of wood by setting a fixed plate and a detection mechanism. The operation is simple and the detection results are intuitive. This avoids the situation where the staff judges the flatness of the wooden board based on their past accumulated experience, resulting in poor detection accuracy. In this way, the device has the advantage of high detection accuracy and improves the quality of the wood.

[0004] The above-mentioned flatness detection device still has the following shortcomings in actual use: when using the flatness detection device to detect the flatness of building wooden boards, dust or impurities are likely to accumulate on the surface of the wooden boards during storage or transportation. The presence of such impurities will affect the flatness detection data. When the staff performs the detection operation, they need to use a soft cloth or a vacuum cleaner to clean the surface of the wooden board, but this will reduce the detection operation of the flatness of the wooden board. Therefore, a flatness detection device for building materials is needed to solve the above problems. Utility Model Content
