In 2016 year, there was a carpentry in USA, they are always received the house renovation projects on peak seasons. The carpentry always hate to measuring the length of the wooden beam between front and behind walls by using the original roller tape measure. It requires the head end to be stuck to the head end of the wooden beam to be measured and stretched to the end without falling off to complete the length measurement. And if the tape measure is not straight, it will greatly affect the test results. Smart carpentry wants to develop a tool with laser measuring funcion to fix this problem.
