1. A triaxial stabilizer for mobile phone, comprising a handheld part, a fixing device for mobile phone, and three motors, an X-axis motor, a Y-axis motor, and a Z-axis motor, which are arranged at top of the handheld part and are orthogonal in a space;

  • wherein the Z-axis motor has a stator connected with the handheld part and has a rotor connected with a stator of the Y-axis motor, the Y-axis motor has a rotor connected with a stator of the X-axis motor, and the X-axis motor has a rotor connected with the fixing device for mobile phone;

    the triaxial stabilizer for mobile phone further comprises a button control circuit and a motor control circuit, wherein a signal output of the button control circuit is connected with a signal input of the motor control circuit, and a signal output of the motor control circuit is connected with the X-axis motor, the Y-axis motor, and the Z-axis motor, respectively;

    the button control circuit is arranged within the handheld part, with buttons thereof protruding out of the handheld part, wherein the buttons include a four-direction navigation key, a function button and a shutter button, and wherein the handheld part is further arranged with an indicator light;

    the four-direction navigation key controls movements of the X-axis motor and the Z-axis motor;

    a rotating shaft of the X-axis motor is rotated to lead the fixing device for mobile phone to perform pitching movement when an up key or a down key of the four-direction navigation key is pressed;

    a rotating shaft of the Z-axis motor is rotated to lead the fixing device for mobile phone to perform yawing movement when a left key or a right key of the four-direction navigation key is pressed;

    the fixing device for mobile phone is switched among different working modes as follows by means of the function button;

    when the function button is pressed one time, the fixing device for mobile phone is switched to a yawing movement following mode, in which the Z-axis motor is in an enabled state while both the X-axis motor and the Y-axis motor are in a lock state;

    when the function button is pressed two successive times, the fixing device for mobile phone is switched to a yawing movement and pitching movement following mode, in which both the Z-axis motor and the X-axis motor are in an enabled state while the Y-axis motor is in a lock state;

    when the function button is long-pressed for one second, the fixing device for mobile phone is switched to a locking mode, in which the X-axis motor, the Y-axis motor and the Z-axis motor are all in a lock state;

    the shutter button is used for confirming photo and video shooting.
