1. The beetle didn't use the beetle connector, and the beetle itself was not so easy to lock. Once locked, they will get stuck.

2. When locking the beetle, pay a little attention. Lock the beetle by hand first, and then rotate it with a hand drill.

As for the disassembly, the beetle can be fixed by some clamping devices first, and then the hand drill can be reversed, and the beetle can be disassembled by relying on the reaction force of the hand drill.
