At present, after the automobile weighing sensor is produced, it is necessary to use a detection device to detect its structural strength, but the existing detection device cannot be adjusted. Since the weighing sensor is usually composed of one sensor or multiple sensors in parallel, it is obvious that the existing detection device cannot meet the needs of different types of weighing sensors and has low practicality.

[0003] To this end, a detection device suitable for multiple groups of parallel sensors is proposed. Summary of the invention
