[0002] A battery shell is a housing used to protect and support the internal components of a battery, usually made of metal material. In order to evaluate the corrosion resistance of the finished battery shell and its surface treatment material in a salt spray environment, a salt spray test device is usually used to test the battery shell, which simulates marine climate or other highly corrosive environments to detect the behavior of the battery shell when exposed to these conditions for a long time.

[0003] After searching, for example, the patent with the publication number CN212180590U specifically discloses a support frame for salt spray test of battery shell. The patent clamps the finished battery shell through a clamping mechanism to avoid the battery shell from falling off during rotation, facilitating the battery shell to fully contact with the salt spray.
