ABSTRACT:
An anti-theft automobile steering wheel lock with an alarm includes an alarm and a lock body. The alarm set fixed on the lock body consists of a circuit board, a buzzer and a battery base. The circuit board possesses a microphone sensor, a vibrating sensor and a warning light. The warning light and the battery base are connected with the circuit board. In using, wrap a fitting member of the lock body around a part of the steering wheel of an automobile and power the alarm set in a detecting state. If a door of an automobile is opened by a thief, air current outside the automobile will flow into the interior of the automobile, inducing the microphone sensor to make the buzzer sound out for warning. If the body of an automobile is struck by a thief, the vibrating sensor will be induced to make the buzzer sound out.
