The sensor comprises an acceleration sensor and/or a gyroscope sensor, the sensor is fixedly connected to the shell, and the control module is connected with the sensor and used for judging whether the inclination angle of the laser level or the received impact exceeds a set threshold value according to the detection result of the sensor. The control module can be a single chip microcomputer. How to detect the tilt angle and determine the impact using an acceleration sensor and/or a gyro sensor is well known to those skilled in the art, and is not an improvement point of the present application, and will not be described herein.
