Display device bearing structure and medical instruments

The application discloses a display device bearing structure and adopt this kind of bearing structure's medical instruments, this kind of bearing structure includes the support arm subassembly, coupling assembling, under bracing arm component and rectilinear movement mechanism. Wherein display device installs on last support arm subassembly, the hookup of coupling assembling and last support arm subassembly, rectilinear movement mechanism installs between coupling assembling and under bracing arm component, make coupling assembling and upward the support arm subassembly relatively the under bracing arm component be relative linear motion. This kind of mode can realize back -and -forth movement (A show direction of arrow) the function of horizontal plane directly, need not too much rotation joint's cooperation, reduces the operation degree of difficulty, and the operation is got up also more simple and conveniently, improves user action and experiences the impression.
