[0002] As a conventional measuring tool, the spirit level has multiple measuring methods such as horizontal and vertical, and is widely used in the fields of construction, mechanical installation, carpentry, etc., among which horizontal measurement is the most frequently used. The traditional spirit level has a relatively single function. In order to meet the needs of modern construction, many multifunctional spirit levels have appeared on the market.

[0003] After investigation, the Chinese patent "A Multifunctional Level Ruler" with the existing application number CN202321598820.6 includes a ruler body with a liquid bubble on it. The characteristic is that a laser rangefinder assembly is also installed on the ruler body. The laser rangefinder assembly includes a clamping frame and a laser rangefinder. The clamping frame is provided with a mounting groove, and compression springs are provided on the surrounding side walls in the mounting groove. A buckle is provided on the outer edge side wall of the mounting groove. The clamping frame is fixedly connected to the ruler body, and the laser rangefinder is movably installed in the mounting groove of the clamping frame. This structure combines the traditional level ruler with the modern laser rangefinder, and can measure multiple data at the same time. It can be used by multiple people at the same time, and the measurement data is accurate. However, the cost is high and the functions are not rich enough.

[0004] The Chinese patent CN202320665001.2, "A Multifunctional Level", includes a device body, legs, a level bubble and a light steel plate.
