Ho in the Po said that in order to save costs, the lock all the parts are to go first to plant material in the lathe come out,TODS, and then re-assemble their own welding. Because it is the first time manufacturing, waste a lot of parts, the cost spent nearly a thousand dollars.
14 years old, where the treasure came from the Mianyang, Chengdu, has been doing odd jobs in the construction industry,tods mens boots, his family was more difficult. But his biggest hobby is to carry out some small inventions, ideas often encountered in daily life from the little things.
. According to his observation, car theft are all destroyed by the cylinder and rode away after the car, angrily, he did not germination of manufacturing a lock cylinder of the idea.
from design drawings to create a finished product, took two years time. In addition, he has been made multi-function devices and curtain machine sowing gadgets.
Bao Ho said in order to develop these small inventions, not only the family spent thousands of dollars savings, but also owed more than twenty thousand yuan debt. And other economic conditions improved slightly, he will lock his patent.
