The clamping mechanism includes a support plate 4 movably installed on the upper surface of the bottom plate 1, and an installation chamber 5 is opened inside the support plate 4. A damping rod 6 and a spring 7 are fixedly installed on the surface of the opposite side of the inner cavity of the installation chamber 5. The damping rod 6 and the spring 7 have the same length. The spring 7 is sleeved on the outer surface of the damping rod 6. A slider 8 is fixedly installed on one end of the damping rod 6 and the spring 7 away from the inner cavity surface of the installation chamber 5. The cross-sectional shape of the slider 8 is the same as that of the installation chamber 5. The cross-sectional shapes of the bins 5 are the same, and the outer surface of the slider 8 is in sliding contact with the inner surface of the mounting bin 5, which is convenient for the slider 8 to move in the mounting bin 5. A connecting block 9 that penetrates the upper surface of the support plate 4 is fixedly installed on the upper surface of the slider 8. A strip hole 11 that is connected to the inner cavity of the mounting bin 5 is opened on the upper surface of the support plate 4. The connecting block 9 is located in the strip hole 11. The outer surface of the connecting block 9 is in sliding contact with the inner surface of the strip hole 11, which is convenient for the connecting block 9 to move on the support plate 4. A V-shaped clamping plate 10 is fixedly installed on the top of the connecting block 9. There are multiple mounting bins 5, and the spacing between two adjacent mounting bins 5 is equal. There are two V-shaped clamping plates 10 on each mounting bin 5.

[0025] The surface of the V-shaped clamping plate 10 is provided with an elastic adaptation mechanism for adapting to battery cells of different shapes. The elastic adaptation mechanism includes two mounting plates 12 fixedly mounted on the inner surface of the V-shaped clamping plate 10. A groove 13 is provided on the surface of the mounting plate 12. A straight plate 14 is rotatably installed inside the groove 13.

A rubber pad 16 is fixedly installed on the surface of the straight plate 14 away from the arc-shaped spring piece 15. A plurality of arc-shaped grooves 17 are provided on the surface of the rubber pad 16 away from the straight plate 14. The angle between the two straight plates 14 on the inner side of the V-shaped clamping plate 10 can be adjusted through the elastic adaptation mechanism to facilitate adaptation to square battery cells of different thicknesses or cylindrical battery cells of different diameters.

[0028] When in use, the two V-shaped clamping plates 10 are pulled toward both sides of the support plate 4, so that the slider 8 moves toward both sides in the installation chamber 5, so that the slider 8 compresses the damping rod 6 and the spring 7, and then the battery cell to be tested is placed between the opposite side surfaces of the two V-shaped clamping plates 10. After loosening the V-shaped clamping plates 10, the damping rod 6 and the spring 7 will return to normal, and then the two V-shaped clamping plates 10 will move toward the side close to the battery cell at the same time until the straight plates 14 on the two V-shaped clamping plates 10 contact the battery cell. The straight plate 14 has a certain elastic activity space through the arc-shaped spring piece 15, and at the same time, the straight plate 14 and the rubber pad 16 can be in close contact with the battery cell. The rubber pad 16 can protect the battery cell, and the arc-shaped groove 17 can increase the friction force on the surface of the rubber pad 16.
