[0002] In recent years, with the rapid development of the automotive industry, cars have become popular among ordinary people. People not only put forward stringent requirements on the economy of cars, but also put forward higher requirements on the safety, environmental protection, comfort and other performance of cars. The car seat angle adjuster is a device for adjusting the seat backrest forward and backward to ensure that the driver and passengers drive under the most comfortable conditions. Therefore, when repairing or producing a car, it is necessary to measure the angle of the seat backrest. The backrest angle is usually required to be within the range of 115°±10°. When measuring the angle of the seat backrest, it is necessary to measure it through the angle measuring dial of the car seat back angle measuring device.
