Description

An object height measuring instrument

technical field

The utility model relates to an object dimension measuring instrument, in particular to an object height measuring instrument.

Background technique

When people measure the height of an object, the head end of the common tape measure is compared to the bottom of the object, the tape measure is rolled up to the top of the object, and then the centimeters on the end of the tape measure are read. However, this kind of embarrassment is often encountered when measuring in this way. First, the height of the object may exceed the length of the tape measure. You have to hold down the tail end of the tape measure and move the tape measure up to continue measuring; Operation at the end tends to take care of one thing and lose another; both situations will affect the measurement accuracy of the object's height. Have again, when the height of object surpasses human body height more, can make people feel that operation is extremely inconvenient, and looking up at the centimeter number on the tape measure end also can read inaccurately.

Especially, for agricultural scientists and technicians, when they measure the plant height of high-stalk crops (such as corn and sorghum) in the test field, since the top of the crop is not rigid or hard, but flexible, if the above-mentioned method It is almost impossible to measure, and therefore not to mention precise.
