[0032] See also Figure 3 、 Figure 4 as well as Figure 6 In some embodiments of this example, an insert block 4 is provided inside the slide groove 3 in the angle measuring device, the rear end of the insert block 4 is fixedly connected to the spring 5, the rear end of the insert block 4 is fixedly connected to the shift block 6, and the insert block 4 is adapted to the slot 23.

[0033] Through the organic cooperation between the slide groove 3 and the insert block 4, when the flip ruler 19 coincides with the straight ruler 1, the insert block 4 is inserted into the slot 23 under the push of the spring 5, locking the straight ruler 1 for easy storage. When it is necessary to rotate and open the flip ruler 19, the push block 6 is turned to make the spring 5 contract, and the insert block 4 is separated from the slot 23, and the flip ruler 19 can be opened.

[0034] See also Figure 4 and Figure 5 In some embodiments of this example, the output end of the motor 10 in the angle measuring device is fixedly connected to a pinion 16, which is meshed with a large gear 17. Through the organic coordination between the motor 10 and the pinion 16, starting the motor 10 drives the pinion 16 to rotate, which in turn drives the meshed large gear 17, thereby driving the turning scale 19 to rotate relative to the straight ruler 1, facilitating angle measurement.

The motor 10 is started by the control button 8 to drive the turning ruler 19 to rotate. The turning ruler 19 and the straight ruler 1 are placed on the object to be measured, and the indicator needle 15 cooperates with the angle plate 20 to observe the angle change.

[0043] The angle sensor 21 is fixedly connected to the turning ruler 19, and the rotating shaft 22 is fixedly connected to the straight ruler 1. Through the principle of electromagnetic induction, when the angle between the straight ruler 1 and the turning ruler 19 changes, the angle is converted into an electrical signal and transmitted to the display screen 7. The two angle measurement methods can be compared with each other to avoid errors.

[0044] When the angle measuring device is not in use, the turning ruler 19 is overlapped with the straight ruler 1, and the insert block 4 is inserted into the slot 23 under the push of the spring 5 to lock the straight ruler 1 for easy storage.
