Big sensor and small sensor switching structure with pin shafts arranged side by side

The invention discloses a big sensor and small sensor switching structure with pin shafts arranged side by side. The big sensor and small sensor switching structure comprises a big sensor, a big connector, a small sensor, a small connector and a tested workpiece installing base. One side of the big sensor is fixedly arranged, the left end of the big connector is connected with the big sensor through threads, and an installing wall is arranged inside the big connector. The small sensor is installed on the installing wall of the big connector. The left end of the small connector is connected with the small sensor through threads, and the left end of the tested workpiece installing base is connected with the right end of the big connector through an upper big pin shaft and pin hole matching structure and a lower big pin shaft and pin hole matching structure, and the middle of the left end of the tested workpiece installing base is connected with the right end of the small connector through a middle small pin shaft and pin hole matching structure. In the testing process of product performance, disconnection and connection disassembling and assembling difficulty of the big sensor and the small sensor in the switching process can be lowered, the workloads of product testing can be reduced, and the efficiency of product testing can be improved.
