[0025] The inner wall of left block 1 is fixedly connected with isolation block 305, the left end of first rotating shaft 304 is fixedly connected with winding block 307, the inside of left block 1 is provided with winding shell 306, the front of left block 1 is fixedly connected with clamping soft column 8, the outer surface of right block 2 is provided with clamping groove 9, the outer surface of clamping soft column 8 is clamped with the inside of clamping groove 9, by being provided with clamping soft column 8 and clamping groove 9, the butt joint between left block 1 and right block 2 is facilitated, so that the device is convenient to store when not in use.

[0026] The left end of the first rotating shaft 304 penetrates the isolation block 305 and the winding shell 306 in sequence and extends to the inside of the winding shell 306, the left end of the winding block 307 is rotationally connected with the inner wall of the winding shell 306, the outer surface of the winding block 307 is fixedly connected with the cloth roll 308, the outer surface of the transparent observation plate 301 is fixedly connected with the inner wall of the left block 1, the outer surface of the winding shell 306 is provided with the through opening 10, the cloth roll 308 in the device is exposed through the through opening 10, the surface data of the cloth roll 308 can be observed through the transparent observation plate 301, and the measured angle is obtained.

[0027] The left side of the winding shell 306 is fixedly connected with the fixed column 309, the left end of the fixed column 309 is fixedly connected with the inner wall of the left block 1, the outer surface of the cloth roll 308 is fixedly connected with the ring cloth 310, one end, away from the winding shell 306, of the ring cloth 310 is fixedly connected with the inner wall of the right block 2, the inner wall of the fixed shell 302 is fixedly connected with the rotating shell 11, and the outer surface of the first rotating shaft 304 is fixedly connected with the inner wall of the rotating shell 11, so that the friction generated when the first rotating shaft 304 rotates is reduced, and the fluency of use of the device is increased.

[0028] The working principle of the utility model is: when using, the left block 1 and the right block 2 are in the clamped state, so the left block 1 and the right block 2 need to be separated, and the angle between the left block 1 and the right block 2 is adjusted through the second rotating shaft 5 and the rotating block 4, so that the left block 1 is close to one edge of the object, then the right block 2 is rotated, so that the right block 2 is close to the other edge, at this time, the angle between the left block 1 and the right block 2 is the angle to be measured of the object, when the right block 2 is rotated, the ring cloth 310 drives the cloth roll 308 to rotate, and the ring cloth 310 is released, then the data on the surface of the cloth roll 308 is observed through the transparent observation plate 301, and the angle of the object is obtained through the conversion rule;

[0029] The conversion rule is, for example: if the thickness of the left block 1 and the right block 2 is d, then the angle deviation between the ring cloth 310 and the actual contact point on the surface of the object to be measured is θ, which can be calculated through the formula θ=f(d), wherein f is a conversion function;

[0030] A specific example is given to illustrate how to use the protractor to measure the angle in the case of different thicknesses, and the conversion result is given, for example: "when the thickness of the left block 1 and the right block 2 is 10mm, if the angle displayed by the ring cloth 310 is 45°, the actual measured angle should be 44.5°, f(d)=displayed degree-k*d;

[0031] The value of k needs to be determined by experiment, which can be done by the following steps: a. manufacturing a standard block with a known thickness, the thickness of which is d; b. measuring the angle of the standard block using a protractor, and recording the displayed angle θdisplay; c. measuring the actual angle of the standard block using a precise measuring tool (such as a precision protractor), and recording the actual angle θexact; d. by comparing θdisplay and θexact, calculate the error ε = θdisplay - θexact; e. since ε = k * d, we can calculate k = ε / d;

[0032] Since the rotation of the cloth roll 308 will drive the clockwork spring 303 to rotate, and the clockwork spring 303 refers to a spring with a helical line in a plane, the spring is a spring with a plane helix, one end of the spring is fixed, and the other end is subjected to a torque, and the material is subjected to a bending moment, and a bending elastic deformation is generated, so that the spring is twisted in its own plane, therefore, when the right block 2 is not subjected to external force, the clockwork spring 303 is automatically retracted, and the pulled-out loop cloth 310 is re-wound to the cloth roll 308, so that the left block 1 and the right block 2 are attached together, facilitating the storage of the protractor when the designer goes out to measure, avoiding the inconvenience of carrying and storing the protractor when the designer goes out to measure, increasing the operation difficulty of the designer, and affecting the work efficiency.

[0033] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
