<p>A laser leveling device, comprising: a remote control device (10) for receiving and transmitting a control command via a Bluetooth signal; a receiving/sending device (20) for receiving and outputting the control command via the Bluetooth signal; and a master control device (30) connected to the receiving/sending device (20) for controlling the operating mode of the laser leveling device according to the control command. Since the effective transmission distance of the Bluetooth signal is very long, and can even reach hundreds of metres, it can achieve the control of the laser leveling device at a farther distance, so that the problem that the remote control distance of the existing laser leveling device is relatively short can be solved.</p> |
