Laser device

One embodiment of the utility model provides a laser device. The laser device comprises a light source module; the lens group shell is detachably connected with the light source module; the optical lens group is connected in the lens group shell; wherein the light source module and the optical lens group can form a light path in the lens group shell. According to the laser device, the optical lens set is arranged in the lens set shell, and the technical effect that a user can conveniently disassemble and assemble the light source module and the lens set shell is achieved in the mode that the light source module and the lens set shell are detachably connected, so that if the light source is damaged, the user can independently replace the light source module, and the user experience is improved. And the optical lens group does not need to be discarded together. Therefore, the laser device can reduce the loss of a user, and provides the disassembly and assembly and self-configuration functions of the laser devic
