[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The auxiliary structure 8 includes fixed frames 81, which are fixedly connected to both sides of the current and voltage tester 5.

[0036] The working principle of the solar cell module IV tester provided by this utility model is as follows: By setting the adjustment structure 7, the test frame 1, power supply box 3, and current and voltage tester 5 are first placed in the storage box 701. Then, the screw 705 on the auxiliary block 706 is rotated by the turntable 707, so that the screw 705 drives the positioning block 703 to move in the slide groove 702 of the storage box 701. When the positioning block 703 moves, it drives the connecting plate 704 to move. The connecting plate 704 drives the spring 709 and the telescopic rod 708 to move. The spring 709 and the telescopic rod 708 drive the limiting plate 710 to move, so that the limiting plate 710 fixes and limits the test frame 1 and the power supply box 3. At the same time, the spring 709 and the telescopic rod 708 can prevent the test frame 1 and the power supply box 3 from being squeezed and worn. The test frame 1 is used to fix the solar cell module and ensure that the battery maintains the correct position and angle during the test. The power supply box 3 is used to fix the solar cell module and ensure that the battery maintains the correct position and angle during the test. Providing a stable current and voltage supply, it is typically used to provide additional power support for certain components in the system. The current and voltage tester 5 is the core equipment used to test the performance of solar cells. By measuring the current and voltage of the battery module under different light conditions, the IV curve is obtained. The tester is usually equipped with a high-precision current and voltage measurement module. The test head 6 provides the necessary electrical contact points for the battery module to measure the current, voltage and other electrical parameters of the solar cell, ensuring that the battery performance can be monitored in real time during the test. The soft pad 711 can prevent the limiting plate 710 from directly contacting the test frame 1 and the power supply box 3, thus avoiding wear on the test frame 1 and the power supply box 3. The limiting rod 712 can limit the positioning block 703, preventing the positioning block 703 from shifting during use. The cleaning cotton 713 can clean the screw 705, making the screw 705 run more smoothly during use.
[0037] By setting the auxiliary structure 8, the insertion rod 85 is first moved inside the connecting block 84 to separate the insertion rod 85 from the adjusting block 86. Then, the handle 83 is moved with the help of the anti-slip sleeve 87, so that the handle 83 drives the protective plate 82 to move inside the fixed frame 81. Then, the control button of the current and voltage tester 5 can be pressed. The anti-slip sleeve 87 can increase the friction of the handle 83 to prevent the person from slipping when moving the handle 83. The ball bearing 88 can reduce the friction of the protective plate 82, so that the protective plate 82 moves more smoothly inside the fixed frame 81.
[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
