Handheld laser transmitting device

The utility model discloses a handheld laser transmitting device which comprises a laser transmitting source, a processor and a sensor. The sensor is used for sensing change of displacement of the device and transmits detection signals to the processor, control signals are generated via the processor, and the laser transmitting source is controlled to be turned on or off. The sensor for sensing the change of the displacement of the device is configured in the handheld laser transmitting device, further, whether the device is picked up or not is judged, the laser transmitting source is automatically controlled to be turned on when the sensor detects that the device is picked up, laser light is transmitted, and service needs of users are met. When the change of the displacement of the handheld laser transmitting device is not obvious within a period of time, the laser transmitting source is automatically controlled to be turned off, and the designed purpose of effectively saving electricity of the device is achieved. Besides, the handheld laser transmitting device is simple in structure, can be automatically controlled to be turned on or off according to service conditions of human bodies, the handheld laser transmitting device is used conveniently, and the intelligent and humanized design of the handheld laser transmitting device is highlighted.
