On opposite side walls in the card slot 301, movable plates 5 are fixedly connected through elastic members 4. The movable plates 5 are slidably installed in the card slot 301. An installation gap 501 for clamping the inner frame 2 is formed between two opposite movable plates 5. A plurality of damping rods 502 are installed between the side walls of the movable plates 5 adjacent to the card slot 301.

[0025] In this solution, after the inner frame 2 is installed in the installation gap 501, two opposite movable plates 5 clamp the inner frame 2 under the action of the elastic members 4; and through the combined action of the elastic members 4 and the damping rods 502, the external force buffer in the axial direction of the inner frame 2 is realized, so as to play a shock-proof role and avoid damage to the solar cell string caused by external force impact.

[0026] In an embodiment of the present utility model, the outer frame 3 includes a U-shaped frame 302 and a fixing frame 303 fixedly connected to the U-shaped frame 302. The U-shaped frame 302 and the fixing frame 303 are connected to form a square shape, and the card slot 301 and the movable plates 5 are both continuously arranged in a square shape.

[0027] In this solution, when installing the inner frame 2, the outer frame 3 is disassembled to form a U-shaped frame 302 and a fixing frame 303. The inner frame 2 is slid into the installation gap 501 between the two movable plates 5 along the notch of the U-shaped frame 302, and then the fixing frame 303 is installed. After the installation gap 501 between the two movable plates 5 in the fixing frame 303 cooperates with the inner frame 2, the U-shaped frame 302 and the fixing frame 303 are fixedly connected by bolts 6, making the installation and disassembly of the inner frame 2 simple and rapid, and capable of clamping the whole inner frame 2, ensuring the stability of clamping; at the same time, when subjected to external force impact, through the full contact between the movable plate 5 and the inner frame 2, the buffering effect can be improved; wherein, two ends of the U-shaped frame 302 are provided with first threaded holes 601, and the fixing frame 303 is provided with second threaded holes 602 that cooperate with the first threaded holes 601, and the bolts 6 pass through the second threaded holes 602 and are threadedly connected with the first threaded holes 601 to fixedly connect the U-shaped frame 302 and the fixing frame 303; wherein, the second threaded holes 602 are countersunk holes, so as to ensure the flatness of the side wall of the fixing frame 303 after the bolts 6 are installed.

After the inner frame 2 and the outer frame 3 are fixedly connected, the opposite side walls of the inner frame 2 are respectively located in the same plane as the opposite side walls of the outer frame 3, ensuring the flatness of the device.

[0032] In an embodiment of the present utility model, a first inclined edge 503 is provided on the side wall of the movable plate 5 in the U-shaped frame 302 along the sliding installation direction of the inner frame 2, so that when the inner frame 2 slides into the installation gap 501 in the U-shaped frame 302, the two movable plates 5 can be slid by the inner frame 2 pressing the first inclined edge 503, so that the installation gap 501 cooperates with the inner frame 2; a second inclined edge 504 is provided on the side wall of the movable plate 5 in the fixed frame 303 along the sliding installation direction of the inner frame 2, so that when the fixed frame 303 is installed, the two movable plates 5 can be slid by the inner frame 2 pressing the second inclined edge 504, so that the installation gap 501 cooperates with the inner frame 2; facilitating the installation of the inner frame 2.
