[0063] In this embodiment: the filling layer 41 is arranged on the inner surface of the seat cushion outer frame 3, so as to provide comfort for the buttocks and legs of the human body; the radiation protection layer 42 is arranged on the upper end of the filling layer 41, and the radiation protection layer 42 adopts iron-based protective cloth to provide radiation protection; the protective net 43 provides additional protection for the filling layer 41 and the radiation protection layer 42 on the lower side; the wear-resistant layer 16 is installed on the inner surface of the protective net 43, and the wear-resistant layer 16 is made of polyurethane coated cloth to reduce the wear on the surface of the seat cushion of the device.

[0064] For details, please refer to Figure 2 The lower end of the cushion frame 1 is fixedly connected with a plurality of fixing columns 5, and the inner surfaces of the plurality of fixing columns 5 are slidably connected with a base 6.

[0065] In this embodiment: four fixing columns 5 are fixed to the lower end of the cushion frame 1 to support the seat of the device, and four bases 6 slide on the inner surfaces of the four fixing columns 5 to provide stable support for the device.

[0066] The working principle and use process of the present invention are as follows: first, when in use, the second double-axis motor 38 is started to drive the two second rotating rods 39 to rotate, and the back frame 11 is driven to adjust the angle under the action of force. At the same time, the two first spur gears 24 are driven to rotate inside the two sliding grooves 22 according to the two connecting plates 25, thereby strengthening the limiting support of the two sliding connecting plates 25. Then, when performing radiation protection work on the upper body of the human body, the first double-axis motor 28 is started to drive the two first rotating rods 30 to rotate, and the two second spur gears 31 are driven to rotate under the action of force. Since the two second spur gears 31 are respectively meshed with the two second racks 27, the entire sliding seat 9 is driven to slide outward, and the two rollers 32 are driven between the two mountings. The interior of the groove 26 slides, and the shielding curtain 10 wrapped on the surface of the winding roller 34 is pulled outward according to the sliding of the sliding seat 9. The rotation of the winding roller 34 drives the external appearance of the torsion spring 35 to twist to accumulate energy. When use is finished, the first dual-axis motor 28 is controlled to reverse, and the torsion spring 35 is used to facilitate the retraction and winding of the shielding curtain 10. When it is necessary to increase the radiation protection effect for the user, a certain amount of copper powder is filled into the storage box 17, and the special powder vacuum cleaner 18 is started to extract the copper powder inside the storage box 17, and the copper powder is transferred to the inside of the storage hose 33 according to the connecting hose 19, so that the external ionizing radiation is absorbed and protected according to the transferred copper powder, thereby playing a role in strengthening the radiation protection of the user's body surface.
