The rotating frame 3 is internally slidably connected with two sliding clamps 6, and the two sliding clamps 6 are symmetrically arranged along the center line of the driving threaded rod 5; the driving threaded rod 5 is threadedly connected to the sliding clamps 6; during operation, when the lithium battery needs to be tested, the lithium battery can be placed between the two sliding clamps 6, and then the second driving motor 501 can be started, so that the second driving motor 501 drives the driving threaded rod 5 to rotate, and then the two sliding clamps 6 are driven to approach each other through the threaded cooperation between the driving threaded rod 5 and the sliding clamps 6 to fix the lithium battery, so that the fixation of the lithium battery during testing can be more stable, and then the rotation of the rotating shaft 4 can be controlled by the first driving motor 301, thereby driving the deflection frame 3 to deflect, so that the angle of the deflection frame 3 can be adjusted, making it more convenient to observe the lithium battery.

[0024] like Figures 1 to 3 As shown, a plurality of fixed suction cups 7 are fixedly connected to the side wall of the sliding clamp block 6, and the plurality of fixed suction cups 7 are regularly arranged in a linear array on the side wall of the sliding clamp block 6; during operation, when the lithium battery is clamped and fixed by the sliding clamp block 6, by arranging the fixed suction cups 7 on the side wall of the sliding clamp block 6, and fixing the lithium battery by the negative pressure of the fixed suction cups 7, the sliding clamp block 6 can fix the lithium battery more stably, and the flexible fixed suction cups 7 can protect the lithium battery, effectively avoiding squeezing between the lithium battery and the sliding clamp block 6, which can easily cause the lithium battery to dent.

[0025] like Figure 1 to Figure 2 As shown, a guide rod 8 is fixedly connected to the interior of the deflection frame 3; the guide rod 8 is arranged in parallel with the driving threaded rod 5; the sliding clamp 6 is slidably connected to the guide rod 8; during operation, when the sliding clamp 6 slides inside the deflection frame 3, the sliding of the sliding clamp 6 is restricted by arranging the guide rod 8 inside the deflection frame 3, so that the sliding clamp 6 is less likely to tilt when sliding, and the sliding of the sliding clamp 6 is more stable.

[0026] like Figures 2 to 3 As shown, a plurality of connecting rods 9 are fixedly connected to the side wall of the sliding clamp 6, and the position of the connecting rods 9 corresponds to the position of the fixed suction cup 7; the ends of the connecting rods 9 are commonly connected to a sliding plate 10; a limiting groove 11 is fixedly connected to the side wall of the deflection frame 3; the sliding plate 10 is slidably connected at the internal position of the limiting groove 11; the sliding clamp 6, the fixed suction cup 7, the connecting rod 9 and the sliding plate 10 are commonly provided with an air guide hole 12 inside, and the air guide hole 12 is set through; during operation, during the sliding process of the sliding clamp 6, the sliding of the sliding plate 10 is restricted by the limiting groove 11, so that the sliding clamp 6 can be more stable during the sliding process. At the same time, when the sliding plate 10 slides with the sliding clamp 6, the space on the side of the rodless cavity inside the limiting groove 11 will expand. When the amount of gas inside the fixed suction cup 7 remains unchanged, the negative pressure inside the fixed suction cup 7 will increase, so that the fixed suction cup 7 can have a better fixing effect on the lithium battery.

[0027] like Figure 4 As shown, a positioning block 13 is fixedly connected to the end of the driving threaded rod 5; the positioning block 13 is rotatably connected to the inner position of the deflection frame 3; during operation, when the driving threaded rod 5 rotates inside the deflection frame 3, the rotation of the positioning block 13 is restricted by the deflection frame 3, so that the positioning block 13 is less likely to tilt during the rotation process, thereby making the rotation of the driving threaded rod 5 more stable.

[0028] like Figure 4 As shown, a plurality of anti-wear balls 14 are provided between the deflection frame 3 and the positioning block 13; the side walls of the anti-wear balls 14 are in contact with the side walls of the deflection frame 3 and the positioning block 13; during operation, when the positioning block 13 rotates inside the deflection frame 3, by providing the anti-wear balls 14 between the deflection frame 3 and the positioning block 13, the sliding friction between the deflection frame 3 and the positioning block 13 can be converted into rolling friction, so that the friction force between the deflection frame 3 and the positioning block 13 is smaller, thereby reducing the wear between the deflection frame 3 and the positioning block 13.

[0029] During operation, when the lithium battery needs to be tested, the lithium battery can be placed between the two sliding clamps 6, and then the second drive motor 501 can be started, so that the second drive motor 501 drives the driving threaded rod 5 to rotate, and then the two sliding clamps 6 are driven to approach each other through the thread cooperation of the driving threaded rod 5 and the sliding clamp 6, so as to fix the lithium battery, thereby making the fixation more stable when the lithium battery is tested, and then the rotation of the rotating shaft 4 can be controlled by the first drive motor 301, thereby driving the deflection frame 3 to deflect, so that the angle of the deflection frame 3 can be adjusted, making it more convenient to observe the lithium battery.

[0030] When the lithium battery is clamped and fixed by the sliding clamp 6, a fixed suction cup 7 is provided on the side wall of the sliding clamp 6, and the lithium battery is fixed by the negative pressure of the fixed suction cup 7, so that the sliding clamp 6 can fix the lithium battery more stably. At the same time, the flexible fixed suction cup 7 can protect the lithium battery and effectively avoid extrusion between the lithium battery and the sliding clamp 6, which may easily cause the lithium battery to dent.

[0031] When the sliding clamp 6 slides inside the deflection frame 3, a guide rod 8 is provided inside the deflection frame 3 to limit the sliding of the sliding clamp 6, so that the sliding clamp 6 is less likely to tilt when sliding, and the sliding of the sliding clamp 6 is more stable.

[0032] During the sliding of the sliding clamp 6, the sliding of the sliding plate 10 is restricted by the limiting groove 11, so that the sliding clamp 6 can be more stable during the sliding process. At the same time, when the sliding plate 10 slides with the sliding clamp 6, the space on the rodless cavity side inside the limiting groove 11 will expand. When the amount of gas inside the fixed suction cup 7 remains unchanged, the negative pressure inside the fixed suction cup 7 will increase, thereby making the fixed suction cup 7 have a better fixing effect on the lithium battery.

[0033] When the driving threaded rod 5 rotates inside the deflection frame 3 , by limiting the rotation of the positioning block 13 in the deflection frame 3 , the positioning block 13 is less likely to tilt during the rotation, thereby making the rotation of the driving threaded rod 5 more stable.

[0034] When the positioning block 13 rotates inside the deflection frame 3, by arranging the anti-wear balls 14 between the deflection frame 3 and the positioning block 13, the sliding friction between the deflection frame 3 and the positioning block 13 can be changed into rolling friction, so that the friction force between the deflection frame 3 and the positioning block 13 is smaller, thereby reducing the wear between the deflection frame 3 and the positioning block 13.
