Embodiment Construction

[0012] Accompanying drawing is the specific embodiment of the present invention. Such as figure 1 , figure 2 As shown, this kind of triangular plate includes a hollow plate body 1 and a protractor 2 located in the hollow part. Two grooves 3 are arranged between the long side of the plate body 1 and the hollow part, and two grooves are arranged on the straight side of the protractor 2 A bar connecting rod 4, the connecting rod 4 is hinged at the midpoint of the groove 3, and can be stuck in the groove 3.

[0013] When using the protractor 2, it can be placed in the hollow part of the plate body 1 for use, and the protractor 2 can also be forwarded until its straight edge coincides with the long side of the plate body 1, which will be more convenient.

[0014] Except for the technical features described in the description, the rest of the technical features are known to those skilled in the art.

Abstract

The invention relates to school supplies, and particularly discloses a triangular plate. The triangular plate comprises a middle hollow plate body and an angle gauge located at the hollow portion and is characterized in that two grooves are formed between the long side and the hollow portion of the plate body, and two connecting rods are arranged on the straight side of the angle gauge; and the connecting rods are hinged to the center points of the grooves and can be clamped in the grooves. When the triangular plate is used, the angle gauge is rotated to the long side of the triangular plate to coincide with the straight side of the angle gauge, and therefore angle measuring is more convenient.

Description

(1) Technical field [0001] The invention relates to a vision correcting product, in particular to a triangular plate. (2) Background technology [0002] Triangle and protractor are commonly used tools for students. At present, there is a tool that combines the triangular plate and protractor. Since the triangular plate and the protractor are fixed together, the protractor is fixed in the hollow part of the triangular plate. Sometimes it is inconvenient to use . (3) Contents of the invention [0003] In order to make up for the defects of the prior art, the present invention provides a settable that is convenient for drawing straight lines and measuring angles. [0004] The present invention is achieved through the following technical solutions: [0005] A triangular plate, comprising a hollow plate body in the middle and a protractor located in the hollow part, characterized in that: two grooves are provided between the long side of the plate body and the hol...
