When detached from the remote controller main body, the remote-control lever assembly is configured to be stored in the storage slots. The clamp assembly is movably connected to the remote controller main body and is capable of unfolding or folding from the remote controller main body. When being folded, the clamp assembly is configured to cover the remote-control lever assembly stored in the storage slots.
