Description

Technical Field

[0001] The utility model relates to the technical field of engineering detection instruments, in particular to a level detection device for engineering detection. Background Art

[0002] Level rulers are widely used in engineering inspection and engineering surveying and mapping. They use the principle of liquid level to directly display angular displacement with a spirit level bubble, and measure the degree of deviation of the measured surface relative to the horizontal position, vertical position, and tilt position.

[0003] After using a spirit level to detect the relative horizontal position, vertical position or tilt position of the measured surface, the surveyor is usually required to draw lines along the edge of the spirit level with a pen. However, since the lines are drawn manually by holding the pen, it is easy for hand shaking to cause the final lines to be crooked, or uneven force to cause the lines to be intermittent. In addition, there is a situation where the person forgets to bring the pen. Utility Model Content
