How to put the drill bit in the rotary drill? I operated for a few hours, but it couldn't block the drill bit at all.

The rotary drill does require a special SDS carbide drill, which has three grooves on the shank. I pull back and press lightly on the drill bit and it will slide into the drill bit. Then, rotate the bit to make sure it is locked in place so that the operation can jam the bit.
