(3) The utility model discloses articulate the angle scale on the connecting rod ingeniously, set up the recess that is used for accomodating the angle scale respectively at connecting rod back upper and lower both ends, and the radius of protractor place circle is less than the length of connecting rod, in the use, measuring device uses the completion back, can fold the protractor to the connecting rod side in the recess, reduces measuring device space occupancy, extension measuring device life.

(4) The utility model discloses set up slide caliper in the connecting rod bottom ingeniously, in measuring device's in-service use process, slide caliper not only can be used for measuring two dimension length, can carry out the precision measurement to the material object moreover, and application range is wider.

(5) The utility model discloses set up the draw-in groove that is used for placing the pen for drawing ingeniously on hand, when increasing the product storage nature, can also place reserve pen in order to be ready for needs from time to time.

(6) The utility model discloses set up the arc template that comprises different radiuses, fretwork ingeniously on the protractor, at the drawing in-process of reality, can select the arc line segment in the arc template as required, drawing efficiency is higher.

(7) The utility model discloses set up the thickness sum of connecting rod and angle scale into the thickness that equals the protractor ingeniously, can guarantee at the drawing in-process, guarantee that the protractor is stable, make measuring device wholly be in on a plane, ensure that measuring result is accurate.

The utility model relates to a multi-functional teaching measuring device has very high practical value and spreading value in teaching measurement apparatus field.
