However, the detection efficiency is too low, and the deviation of the positioning device with an unstable structure during the detection process will also cause a reference comparison difference in the detection operation, thus affecting the detection operation. Therefore, those skilled in the art have provided a pressure sensor detection device to solve the problems raised in the above background technique. Summary of the Utility Model
