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 and sensing a raising/lowering-controlling operation of moving or rotating the portable device;

    a memory storing a threshold angle; and

    a processor installed in the case and electrically connected to the signal transmitter, the tilt sensor and the memory, the processor being configured to generate a raising/lowering-controlling signal according to the raising/lowering-controlling operation, and transmitting the raising/lowering-controlling signal by the signal transmitter to the external electrical adjustable apparatus for making the external electrical adjustable apparatus raise/lower according to the raising/lowering-controlling signal, the processor being configured to determine that a carrying structure of the electrical adjustable apparatus has collision when receiving any 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.
