1. A portable device for controlling an external electrical adjustable apparatus, comprising:

  • a case;

    a signal transmitter installed in the case and connected to the electrical adjustable apparatus;

    a tilt sensor sensing a tilted angle;

    a memory storing a threshold angle;

    a human-machine interface used to receive operation and trigger a raising/lowering-controlling signal;

    a standby unit installed in the case and electrically connected to the human-machine interface; and

    a processor installed in the case and electrically connected to the signal transmitter, the tilt sensor, the memory, the human-machine interface and the standby unit, the processor being configured to determine that a carrying structure of the electrical adjustable apparatus has collision when receiving the raising/lowering-controlling signal used to control the electrical adjustable apparatus and the tilted angle is not less than the threshold angle, and sending a stopping signal to the electrical adjustable apparatus via the signal transmitter for making the electrical adjustable apparatus stop raising/lowering the carrying structure;

    wherein the standby unit forwards the raising/lowering-controlling signal received from the human-machine interface to the processor, and keeps a path between the human-machine interface and the processor conductive for a standby time when failing to receive the raising/lowering-controlling signal.
