At this time, the clamping rod 905 is rotated. However, during the rotation of the clamping rod 905, the clamping block 907 and the clamping hole 904 are fixed together due to the action of the spring 906, so that the 12V and 24V fast switching DC composite battery box for testing is easy to install.

[0025] The transparent box 1 is provided with an illumination mechanism 2 on both sides thereof. The illumination mechanism 2 comprises a mounting plate 201, an illumination lamp 202, a protective shell 203 and an illumination switch 204. The mounting plate is connected to the transparent box 1.
