Stand for standard measuring devices

This is a stand for the standard Chinese 7-segment display modules. You can find them with all kinds of displays from LED, LCD to OLED. They can measure everything. The one in the pictures is measuring battery voltage.

The display is kept in place with its own claws, so it is removable. 
The model itself is in two parts: the stand and the display holder. On the backside are holes so wires will come out from there.
