Description

Right angle ruler Technical Field The utility model relates to the technical field of woodworking instruments, in particular to a square. Background The woodworking square is one of the most basic and important measuring and marking tools in woodworking work. Its core function is to inspect and create precise 90 degree right angles, and also to commonly draw lines (especially vertical and parallel lines) and to inspect the flatness of the work piece. Typically consisting of two parts, a long and wide blade and a narrower and shorter blade. The two parts are permanently attached together (typically integrally formed or precision fixed with rivets/screws) at a precise 90 degree angle, forming a stable "L" shape. But the fixed L-shaped ruler cannot meet the daily diversification of use. The Chinese patent with the bulletin number of CN203132444U discloses a multifunctional wood ruler in the day of 8 months and 14 days in 2013, which comprises a ruler body, wherein the ruler body consists of two rulers, each ruler consists of a fixed section and a sliding section, two side edges of the fixed section are provided with sliding grooves, the sliding sections are clamped in the sliding grooves, the two rulers are movably pinned together at the zero scale position of the fixed section by a fixed shaft, so that the two rulers can freely rotate along the fixed shaft, the lower end of the fixed shaft is provided with a positioning needle, and the positioning needle is fixed at the center of the fixed shaft. The multifunctional carpenter's rule consists of two telescopic scales, so that two-dimensional coordinates can be accurately positioned, and particularly when a plurality of processing points with the same parameters are positioned, all positioning points can be quickly determined by only setting the length of the scale once, and the positioning efficiency is very high. However, this patent discloses only one type of scale which is rotatably arranged, but does not disclose a specific rotation structure, and cannot be used at non-right angles. It is therefore necessary to provide a square with a rotatable scale. Disclosure of Invention The utility model aims to overcome the defects of the prior art and provide a square, which aims to solve the technical problem that the square cannot be used at a non-right angle in the prior art. In order to achieve the above purpose, the utility model provides a right angle ruler, which comprises a ruler head and a ruler body rotatably arranged on the ruler head through a rotating shaft, wherein the ruler body is provided with a plurality of grooves, the grooves form a ring shape by taking the rotating shaft as the center, the ruler head is provided with an elastic column, the elastic column is provided with a bulge, and the bulge can be clamped into different grooves in the rotating process of the ruler body. Preferably, the elastic column comprises a shell and an elastic body arranged in the shell, the bulge is a sphere clamped on the shell, and the bulge is connected with the elastic body and can compress the elastic body. Preferably, the elastic columns are multiple, and the distances between the elastic columns and the rotating shaft are equal. Preferably, the number of the elastic columns is four, the number of the two elastic columns with the short distance is one, and the two groups of the elastic columns are bilaterally symmetrical. Preferably, the ruler body is provided with a plurality of rows of scribing holes, and the ruler body is provided with a plurality of runway holes. Preferably, the ruler head comprises two ruler head pieces, the ruler body is arranged between the ruler head pieces, and the rotating shaft is a screw and can be connected with the two ruler pieces. Preferably, the ruler head is provided with a stud at one side far away from the ruler body, the stud is connected with two ruler sheets, the ruler body is provided with a clamping groove, and the stud can be clamped on the clamping groove in the rotation process of the ruler body. Preferably, a leveling post is arranged between the two ruler head pieces, and the part of the leveling post protruding out of the ruler head pieces is a cylinder and is equal to the thickness of the ruler body. Preferably, the ruler head is provided with leveling column mounting holes and scribing column mounting holes. Compared with the prior art, the right angle square provided by the utility model has the beneficial effects that: 1. The ruler head and the ruler body can rotate, and can be positioned at different angles through the matching of the grooves and the protrusions, so that positioning and scribing at different angles are realized. 2. The elastic column is matched with the bulge to stretch, so that the ruler body can be fixed at the position of the groove, and the positioning is simpler. The features and advantages of the present utility model will be described in detail by way of example with reference to the acc
