Description

Multifunctional protractor convenient to store Technical field: The utility model relates to the technical field of stationery, in particular to a multifunctional protractor convenient to store. The background technology is as follows: The protractor is an indispensable measuring tool for students in the learning process, and along with the development of modern education, the learning pressure of the students is increased gradually, and more stationery for various learning needs to be carried on school is increased. The traditional protractor mainly has a semicircular or triangular plate-shaped structure, the occupied area is large, a pen bag carried by a student is of a cylindrical structure, the triangular or semicircular protractor cannot be placed in the pen bag, the traditional protractor only has a single angle measuring function, the student needs to carry a plurality of measuring scales with different functions in the daily school process, and the measuring scales are not provided with corresponding adapting structures, so that the carrying tool quantity is large, the storage is affected, and the problem of inconvenience in carrying exists. In addition, at present, students learn vernier calipers, rely on teaching aid and picture examples of school, and practical operation's opportunity condition is few, lacks a simple and easy vernier calipers that non-high accuracy measured but can realize the reality and be used for student to practice the reading. The utility model comprises the following steps: accordingly, the utility model aims to provide a multifunctional protractor which has a simple structure and is convenient to store. The multifunctional protractor is characterized in that the protractor body is of a tubular structure and consists of a supporting ruler and a functional ruler, a first fixing cap and a second fixing cap are respectively and fixedly arranged at two ends of the protractor body, and angle scale marks are arranged on the functional ruler. Further, the angle scale mark is composed of a plurality of scale marks. Further, on a line passing through the zero point of the angle scale mark and perpendicular to the edge where the zero point is located, there is a center point of the angle scale mark. Further, there is a center point mark on the support ruler. Further, connecting portions are arranged at two ends of the supporting ruler, and the first fixing cap and the second fixing cap are respectively fixed on the two connecting portions. Further, the connecting portion is a cylinder with external threads, and the inner walls of the first fixing cap and the second fixing cap are provided with internal threads matched with the connecting portion. Further, length scale marks are arranged on the supporting ruler, and scale marks are carved on the second fixing cap. Further, the zero point of the graduation mark is a round edge at any end of the second fixing cap, and the zero point of the length graduation mark is a round edge at one end of the opening of the first fixing cap. Further, at least one of the two long sides of the functional ruler is a straight side, and the length of the straight side is greater than 1/2 of the length of the supporting ruler. The utility model has the advantages that: The angle gauge is integrally of a circular tube structure so as to be conveniently contained in a pen bag, integrates the functions of the angle gauge and a vernier caliper besides the functions of drawing lines and measuring lengths of a common ruler, is provided with threads at one end, is convenient for fixing a supporting ruler and a functional ruler, and is outwards expanded by the threads, for example, a pen point of a neutral pen is used as a fixing structure, so that the function of the pen is realized, the expansion direction is extremely wide, the angle gauge can be used for drawing angles in a range, and the vernier caliper can be used for learning practice readings of using the vernier caliper by students.
