Photoelectric equipment fault maintainability detection device

The invention discloses a fault maintainability detection device for photoelectric equipment. The fault maintainability detection device comprises a cabinet, a protection mechanism, an operation table, a first rotary connecting piece, a first display screen, a second rotary connecting piece and a second display screen, the protection plate in the protection mechanism can protect the display device in the storage groove in the cabinet, so that the display device is not prone to damage, after the protection mechanism is opened, the operation table can be pulled out of the storage groove, then the two display screens are unfolded by rotating the two connecting pieces, and due to the fact that the rotating joints of the two connecting pieces are different, the operation table is not prone to damage. When the two display screens rotate and are unfolded, the two display screens can be symmetrically spliced without dislocation, so that personnel can better observe the display screens during front analysis, different
