Abstract

The invention provides a portable drawing T-square comprising a shell and a straight ruler portion. At least one storage cavity used for storing the straight ruler portion is arranged in the shell. The side wall of the shell of the storage cavity is provided with an opening. One end of the straight ruler portion extends into the storage cavity from the opening, and the end of the straight ruler portion is hinged to the cavity wall of the storage cavity. The straight ruler portion can be placed in a storage cavity of the shell. The defects that an original T-square is inconvenient to carry, prone to breakage and the like are avoided. The portable drawing T-square is small in structure volume, low in manufacturing cost and convenient to carry, and a student can conveniently carry the T-square to conduct drawing design work.

Description

technical field [0001] The invention relates to a portable drawing T-square. Background technique [0002] At present, in the teaching of gardening, landscape architecture, urban and rural planning, architecture, civil engineering and other majors, manual drawing of planning and design scheme drawings is often used. One of the important drawing tools that often needs to be used is a T-square. The commonly used specifications of the T-square are 60mm and 90mm. The length of the ruler head is 26cm and the thickness is 5mm. They correspond to the drawing of A1 and A2 drawings respectively. Students need to carry them frequently in class, but because of the long length, it is inconvenient to carry and in the It is easy to break due to improper operation during use, which brings inconvenience to students. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a portable drawing T-square with reasonable structure and easy st...
