Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, a tool for economic management mapping includes a main body 1, a cavity 2 is disposed inside the main body 1, a rotating rod 3 movably penetrating and extending to the outside of the main body 1 is connected inside the cavity 2, a first gear 4 is disposed on one side of the rotating rod 3, a second gear 5 mutually matched with the first gear 4 is disposed inside the cavity 2, a connecting rod 8 is fixedly disposed on the outside of the rotating rod 3, one end of the connecting rod 8 extends to the outside of the cavity 2, an adjusting rod 6 movably penetrating and extending to the outside of the main body 1 is disposed on one side of the second gear 5, and an angle pointer 7 is disposed on one side of the rotating rod 3 away from the first gear 4.

According to the angle drawing device, the angle is drawn or measured by arranging the first gear 4, the second gear 5, the adjusting rod 6, the connecting rod 8, the angle pointer 7 and the like, when the angle is required to be measured or drawn, the connecting rod 8 is manually shifted to one side of an angle line, the angle pointer 7 rotates on the main body 1 in the rotating process of the connecting rod 8, the adjusting rod 6 drives the second gear 5 to rotate by adjusting the adjusting rod 6, the first gear 4 is driven to rotate by the second gear 5, the connecting rod 8 rotates, the angle required to be drawn can be adjusted by observing the rotating condition of the angle pointer 7 in the rotating process of the adjusting rod 6, the angle is more accurate in drawing by adjusting the adjusting rod 6, and the working efficiency is improved.

Please refer to fig. 1, the front ends of the first ruler 10 and the second ruler 11 are both provided with length scale marks 12, and the length scale marks 12 are provided to facilitate measuring the drawing length.

Please refer to fig. 2, the cavity 2 is provided with a slot matching with the connecting rod 8, the connecting rod 8 can rotate in the cavity 2 conveniently by the slot, the connecting rod 8 can drive the angle pointer 7 to measure the angle, and the drawing is convenient.
