The first variable distance module is fixedly mounted on the mounting frame. There are multiple first slide rails, and the multiple first slide rails are respectively fixedly mounted on the multiple output sliders of the first variable distance module.

[0032] The variable pitch component 2 includes a first variable pitch module 21, a first slide rail 22, a slider 23, a second slide rail 24 and a second variable pitch module 25. The first variable pitch module 21 and the second variable pitch module 25 are provided with the same number of output sliders. The first variable pitch module 21 is fixedly mounted on the mounting frame 1. There are multiple first slide rails 22, and multiple first slide rails 22 are respectively fixedly mounted on multiple output sliders of the first variable pitch module 21.

The second slide rail 24 is perpendicular to the first slide rail 22. The second variable pitch module 25 is fixedly mounted at the lower end of the first variable pitch module 21, and multiple output sliders of the second variable pitch module 25 are respectively fixedly connected to multiple second slide rails 24.

[0033] Both the first variable pitch module 21 and the second variable pitch module 25 are provided with four output sliders.

[0034] When the present utility model is in use, the four groups of output sliders of the first variable pitch module 21 drive the first slide rail 22 to be adjusted at equal intervals. The first slide rail 22 drives the sliders 23 thereon to slide along the second slide rail 24. The four groups of output sliders of the second variable pitch module 25 drive the second slide rail 24 to be adjusted at equal intervals. The second slide rail 24 drives the sliders 23 to slide along the first slide rail 22, so as to realize the adjustment of the distance between the sliders 23 in the X-axis direction and the Y-axis direction. Thus, the load component 3 on the sliders 23 can be adapted to photovoltaic modules to be tested with different sizes. The distance is adjusted through the adjustment component 41 to adapt to photovoltaic modules with different sizes, and the photovoltaic module is clamped and fixed through the clamping component 42.

When the downward pressure of the cylinder 31 gradually increases, the photovoltaic module deforms, thereby performing a mechanical load test on it. At the same time, through the floating joint 32, the output end of the cylinder 31 is floatingly connected to the suction cup 33, so that the suction cup 33 and the photovoltaic module always remain in contact.
