In use, the sensor is placed on the base 1, the wiring port is inserted into the socket module 4, the driving component 33 drives the conductive rod 31 to connect to the wiring hole 32 after passing through the sensor detection hole, the current is adjusted by the current adjustment module, compared with the current detected by the sensor, and displayed by the display module.

[0033] In this way, by setting up the wiring hole 32, conductive rod 31, and socket module 4, the real-world operating environment of the sensor is simulated. By comparing the output current and the detection current, the sensor's status is detected, simplifying the detection method and improving detection efficiency. Simultaneously, in conjunction with transfer devices such as robotic arms, automation of the detection process is easily achieved, further improving detection efficiency.

[0036] As one specific embodiment of a test fixture for a Hall sensor provided in the application, a push switch 34 is fixedly installed on the base 1. The push switch 34 is connected to the drive unit 33 and is located on one side of the socket module 4.

[0037] Overall, by setting up a push switch 34, pressing the sensor during installation triggers the drive unit 33, which in turn drives the conductive rod 31 into the detection state.

[0040] In some feasible embodiments, a mounting element is installed at the end of the conductive rod 31, and a roller is rotatably mounted on the mounting element. The roller contacts the side of the cam 332, which is rotatably mounted on the base 1.

At the same time, by replacing the replaceable cover 12, the socket module 4 that adapts to the sensor pins can be replaced, so as to adapt to the detection work of different sensors.

[0043] Furthermore, the mounting section 11 is fixedly mounted with multiple slide rails 13 from top to bottom, and the replaceable cover 12 is inserted and mounted on the slide rails 13.
