Novel instrument for gradient detection

The novel instrument comprises a bubble level, a vertical rod and a horizontal rod, the bubble level is embedded in the top end of the vertical rod, a containing groove is formed in one side of the vertical rod, the horizontal rod is embedded in the containing groove, the top end of the horizontal rod is rotationally connected with the inner wall of the containing groove, a telescopic cavity is formed in the horizontal rod, and the telescopic cavity is connected with the vertical rod. A scale rod moving along the telescopic cavity is arranged in the horizontal rod, slope ratio scales are arranged on the scale rod, a storage cavity is formed in the end, away from the horizontal rod, of the scale rod, a steel wire is arranged in the storage cavity, and the outer end of the steel wire extends out of the storage cavity and is provided with a limiting block. The slope detection device is convenient to operate, suitable for detection of slopes with large slopes and high slopes, simple in structure, easy to produce,
