Laser processing head capable of unlocking safety setting through single key

The utility model provides a laser processing head with single-key unlocking safety setting, which is used for processing workpieces and comprises a shell (1), a lens component, a light emitting button (2), a light emitting indicator lamp (3) and a control module. According to the laser processing head capable of unlocking the safety setting through the single key, an operator can determine the current state of the laser processing head by observing the state of the light-emitting indicating lamp 3, and misoperation cannot be caused. Compared with a single-button mode in the prior art, the laser processing head has the advantages that the unlocking condition for emitting laser is added, the situation that the laser processing head can emit laser due to the fact that the button is touched by mistake is effectively reduced, and the safety performance of the laser processing head is effectively improved; compared with a double-button mode in the prior art, the laser can be safely emitted only by operating one bu
