When the rotating shaft 3 rotates, the threaded body 31 is driven to rotate, so that the stud 4 is axially displaced, and the first reflector 54 is further driven to be displaced, and then the distance between the first reflector 54 and the second reflector 55 is changed, so that the light intensity is changed.
Optionally, the angle detecting device 5 further includes: a light emitting device 56 and a second sensor connected to the light emitting device 56; the second reflector 55 is located in the light emitting direction of the light emitting device 56, and the light emitting device 56 is disposed on a main board of the electronic device;

When the rotating shaft 3 rotates, the stud 4 is displaced axially, and the distance between the first reflector 54 and the second reflector 55 is changed. Since the second reflector 55 is located in the light emitting direction of the light emitting device 56, the infrared light emitted from the light emitting tube is incident on the second reflector 55 and then reflected by the second reflector 55 to the first reflector 54; the infrared light is reflected by the first reflector 54, then enters the second reflector 55 again, and is reflected by the second reflector 55 to the light receiving tube. If the distance between the first reflector 54 and the second reflector 55 changes during the reflection of infrared light, the overall optical path length changes. Moreover, due to the effect of the light blocking foam 561, the light intensity received by the light receiving tube changes, so that the folding angle can be calculated.
