PROBLEM TO BE SOLVED: To solve the problem wherein even though a carpenter's square, a plumb bob, a level and a tape measure are needed at a construction site, they are difficult to put in a pocket, except the tape measure. SOLUTION: Tools are assembled compactly, as well as together, and as a result of putting them all in pockets, when they are not in use, they will not be forgotten or lost.
