5. The electronic scale display structure according to claim 4, wherein a first inclined surface is provided on an outer side surface of the clamping block, a second inclined surface is provided on an outer side surface of the second clamping piece, and the first inclined surface abuts against the second inclined surface in a process that the receiving panel slides from the second working position to the first working position.
6. The electronic scale display structure of any one of claims 1-5, further comprising an elastic member coupled between the receiving panel and the scale housing for providing the receiving panel with a movement tendency to slide relative to the scale housing from the first operating position to the second operating position.
7. The electronic scale display structure according to claim 6, wherein the receiving panel is provided with a limit protrusion, and the limit protrusion is used for preventing the receiving panel from falling off the scale housing when sliding from the first working position to the second working position.
8. The electronic scale display structure of claim 1, further comprising a transparent mirror mounted at the propagation port.
9. A projection electronic scale with a drawer type receiving panel, which is characterized by comprising a scale body and the electronic scale display structure according to any one of claims 1-8, wherein a main module pcb and a weighing sensor are arranged in the scale body, and the display assembly and the weighing sensor are electrically connected with the main module pcb.
