[0027] A positioning plate 3 is fixedly installed on the top of the test bench 1. A fixing block 4 is fixedly installed on one side wall of the power supply test device body 2. A slot 5 adapted to the fixing block 4 is opened on one side wall of the positioning plate 3. The fixing block 4 is slidably inserted into the interior of the slot 5.

[0028] The clamping component 6 includes two groups of fixed sleeves 601. Both groups of fixed sleeves 601 are fixedly installed on the top of the positioning plate 3. Positioning rods 602 are slidably inserted into the interiors of both groups of fixed sleeves 601.

[0029] By setting the fixed sleeve 601, the positioning rod 602, the pull plate 603 and the reset spring 10 for coordinated use, when the power supply test device body 2 needs to be positioned, the fixed block 4 on its side can be directly inserted into the inside of the slot 5, and the fixed block 4 automatically lifts the positioning rod 602. At this time, the reset spring 10 is in a stretched state. When the fixed block 4 is fully inserted into the inside of the slot 5, the positioning rod 602 is firmly inserted into the inside of the jack 13 by utilizing the return force of the reset spring 10, so as to achieve the effect of positioning the power supply test device body 2, and the operation is simple and quick;

[0030] A limit block 11 is fixedly installed on the inner wall of the fixed sleeve 601, and a limit groove 12 adapted to the limit block 11 is provided on the outer wall of the positioning rod 602.

By setting the first electric push rod 801 and the clamping plate 802 for use together, the first electric push rod 801 can drive the clamping plate 802 to move through the telescopic end when working, so that the AC and DC power supply to be tested can be clamped and positioned, avoiding the situation of position deviation during the subsequent anti-stamping test, which is conducive to improving the stability of the test process;

As the second electric push rod 901 continues to operate, the pressure detection device 903 can resist the AC and DC power supply. Stamping test, the pressure detection device 903 is realized based on the interaction of mechanics and electronic technology. The sensor is the core component of the pressure detection device, which is responsible for converting the physical quantity (pressure) into an electrical signal. Commonly used sensors include piezoresistive sensors, piezoelectric sensors and strain sensors. When the object under test exerts pressure, the sensor can sense the change in pressure and generate corresponding electrical signals. Subsequently, the signal amplifier will amplify these weak electrical signals to improve the measurement accuracy and signal-to-noise ratio of the tester. Finally, the data acquisition and processing system will be responsible for collecting, processing and storing test data, and analyzing and calculating the data according to the preset algorithm to obtain the test results.
