These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic way, so they only show the components related to the present utility model.

[0030] As Figure 1 shown, a radioactive drug radiation safety protection device includes: a bottom plate 1, a protection mechanism 7 arranged on the upper surface of the bottom plate 1, an inner cover 2 arranged on the upper surface of the bottom plate 1, and an outer cover 3 arranged on the circumferential outer wall of the inner cover 2.

[0033] As Figure 4 shown, a plurality of through placement holes 702 are opened on the upper surface of the extrusion plate 701, a plurality of placement grooves 705 are opened on the upper surface of the placement plate 704, the plurality of placement holes 702 respectively coincide with the positions of the plurality of placement grooves 705, a plurality of rubber rings 703 are fixedly connected to the bottom of the extrusion plate 701, and the plurality of rubber rings 703 are respectively located where the plurality of placement holes 702 coincide.

[0034] As Figure 5 shown, through insertion holes 709 are opened on the upper surfaces of the limit plates 707, and the insertion holes 709 penetrate through the fixed rods 706

[0035] , the insertion rod 711 is located inside the insertion hole 709 and is slidably connected, and a plurality of through air holes 710 are formed in the circumferential inner wall of the insertion hole 709.

[0036] It should be noted that the protection mechanism 7 adopts a combination of components such as the fixed rod 706, the extrusion plate 701, the placement plate 704, the buffer spring 708, the limiting plate 707, and the insertion rod 711, providing stable support and effective buffering.
