Preferably, the material of the slider is wood, which has a lower mass than the round bar.

Preferably, the fixing block is made of wood, and the weight of the fixing block is lighter than that of the round bar.

Preferably, the original length of the spring is half the length of the round bar.

The portable gradient measuring instrument has the following beneficial effects:

1. the leveling round rod is leveled through the leveling bubble, the angle measuring ruler and the thin line can be positioned in the same vertical plane through adjusting the contact point of the round rod and the slope, when the measuring instrument is in a balanced state, the scale value of the angle measuring ruler is recorded, and the sum of the scale value and the slope value is the slope value.

2. The invention can check the scale value of the angle ruler.

3. Simple structure, light weight, portability and simple operation. The invention has the advantages of less material consumption, convenient production, low cost and environmental protection, and is a portable instrument for testing various wall surfaces, board surfaces and slopes of soil slopes under the conventional condition.
