The utility model belongs to the technical field of laser protection devices, and particularly relates to a laser melting deposition local protection device which comprises a laser emission head outer wrapping shell and a laser lens protection mechanism inserted into the laser emission head outer wrapping shell. A through hole penetrating through the shell is formed in the middle position of the laser emission head wrapping shell, the size of the through hole is the same as that of the laser emission head, and the laser lens protection mechanism comprises a fixing plate, a bolt, a lower clamping plate, a fixing block, an upper clamping plate, a buckling mechanism, a plug pin and a laser focusing mechanism. According to the laser melting deposition local protection device, the buckling mechanism is arranged to adjust opening and closing of the upper clamping plate and the lower clamping plate so that the laser focus lens can be fixed between the upper clamping plate and the lower clamping plate, the sealing ga
