The purpose of setting the tough spring 21 is to utilize the elastic force of the tough spring 21 itself to effectively move the insulating plate 20.

[0028] See also Figure 4 and Figure 5 One end of the second linkage plate 3 is rotatably connected to the top of the first support block 4. The setting of the first support block 4 provides effective support for the balance of subsequent components. The bottom of the first support block 4 is fixedly connected to the top of the working plate 8.

The setting of the positioning cylinder 11 facilitates the preliminary positioning of the battery cell body 12.

[0029] See also Figure 1 and Figure 2The outer wall of the working plate 8 is fixedly connected to the inner wall of the protective shell 13. A heat dissipation hole 14 is provided on one side of the protective shell 13. The setting of the heat dissipation hole 14 can effectively discharge the heat. The bottom of the protective shell 13 is fixedly connected to the top of the balancing base plate 15. The bottom of the balancing base plate 15 is fixedly connected to the top of the balancing base 16. There are four groups of balancing bases 16. The four groups of balancing bases 16 are evenly distributed at the bottom of the balancing base plate 15.

The bottom of the heat conducting plate 10 is fixedly connected to a heat dissipation vertical plate 23. The heat dissipation vertical plate 23 is a prior art and will not be described in detail.

[0031] See also Figure 5 A force-bearing cylinder 9 is fixedly connected to the top of the working plate 8, and the top of the second linkage plate 3 is fixedly connected to the bottom of the limit frame 5. There are two groups of limit frames 5. The bottoms of the two groups of limit frames 5 are fixedly connected to the top of the second linkage plate 3.

The limiting plug plate 6 and the force-bearing cylinder 9 cooperate with each other, which can effectively maintain a long-term positioning effect and is not prone to loosening.

[0033] Working principle: First, place the battery cell body 12 on the heat conducting plate 10, outside the heat conducting plate 10, and use external force to drive the control pull ring 1 to move, so that the first linkage plate 2 rotates under the action of the second linkage plate 3, and the second linkage plate 3 is driven to rotate on the first support block 4. At the same time, due to the movement of the first linkage plate 2, the linkage center axis 7 on the limit plug 6 moves, and under the action of the groove in the middle of the first linkage plate 2, the limit plug 6 slides in the limit frame 5, so that the limit plug 6 is accurately inserted into the groove in the force-bearing cylinder 9, and at the same time, the second linkage plate 3 is rotated, so that the insulating plate 20 contacts with the battery cell body 12. At this time, the guiding single rod 19 slides in the second linkage plate 3. Under the action of the elasticity of the toughness spring 21 itself, the insulating plate 20 contacts closely with the battery cell body 12, thereby forming a positioning effect. Then the refrigeration blowing device 17 is started to work, and the cold air produced passes through the shunt pipe 18, driving the heat in the heat dissipation vertical plate 23 placed under the heat conduction plate 10, so that the heat is discharged from the heat dissipation hole 14, thereby effectively testing the battery cell bodies 12 of different specifications, and increasing the practicality of the light attenuation test device.
