1. A gyroscope, comprising:
a casing, wherein the casing is provided with a rotation axis, and a gravity center of the casing lies on the rotation axis;
a motor fixedly mounted on the casing, wherein an output shaft of the motor is coaxial with the rotation axis, an end of the output shaft away from the motor is located outside the casing, and the casing is rotatable around the rotation axis with the end of the output shaft away from the motor as a fulcrum;
a circuit board, wherein the circuit board is provided on the casing and is configured to move with the casing, the circuit board is provided with a power supply and a current amplification circuit, the motor is connected to the power supply through the current amplification circuit, so that a current output by the power supply is amplified by the current amplification circuit and delivered to the motor to control the motor to operate; and
at least two tilt switches, wherein the at least two tilt switches are connected in series to the current amplification circuit for jointly controlling an on/off of the current amplification circuit, the at least two tilt switches are arranged at intervals on the circuit board, each tilt switch has an off state and an on state, when the gyroscope is stationary at any angle, at least one of the tilt switches is in the off state, and when the casing is rotated, all the tilt switches are in the on state.
