It should be noted that the shape of each detection tooth and detection slot is not limited to an isosceles trapezoid, and its shape is consistent with the shape of the end face teeth of the gear ring to be detected, such as an isosceles triangle, etc. The isosceles trapezoid in this embodiment is only an example, and the specific shape is not limited in this embodiment.
