Origin:
In the history of scientific and technological inventions in the world, China also invented the world's first tape measure, which was invented in ancient Huizhou (now Huangshan City). This exciting and little-known information was learned when we visited the memorial hall of Cheng Dawei's former residence, a famous mathematician, abacus operator and inventor in Ming Dynasty.
Located in the center of Huangshan Mountain, the memorial hall was built on the basis of Cheng Dawei's former residence (1533- 1606) and the Cheng ancestral hall. The first tape measure in the world was invented by him around 1578. At that time, it was called the "measurer", so Cheng Dawei was called the "father of tape measure".
Compared with the current steel tape and leather tape, the "measurer" is much bigger, but from its principle, structure, use and usage, people have to admit that it is the prototype of the tape measure. It consists of a wooden coat, a cross, a bamboo ruler, an iron swivel, a drill foot and a ring. The rod ruler is put in and taken out from the plate hole of the jacket, which is convenient for the drilling foot to be accurately inserted into the field measurement point and easy to carry. I took it out curiously and tried it. Sure enough, the ruler is easy to put away, and it is convenient to measure, read and carry.
