The plurality of first light-shielding sheets 4 and the plurality of second light-shielding sheets 5 are respectively set as arc-shaped sheets, and connection blocks 7 are fixedly connected to the side walls of the plurality of first light-shielding sheets 4 and the plurality of second light-shielding sheets 5 respectively. A elastic metal ring 8 is simultaneously and movably sleeved inside the plurality of connection blocks 7.

[0027] A plurality of guide blocks 9 are respectively fixedly connected to the inside of the plurality of first light-shielding sheets 4. Guide grooves are respectively opened on the side walls of the plurality of second light-shielding sheets 5. The guide blocks 9 are slidably arranged on the inner wall of the guide grooves. The cross-section of the guide blocks 9 is set as a trapezoid, and the second light-shielding sheets 5 are located on the inner wall of the guide grooves and are matched with the guide blocks 9.

[0028] During use, the fixed cover 1 is arranged above the irradiation device 15, and the irradiation range of the irradiation device 15 can be controlled. The multiple first light-shielding sheets 4 and the multiple second light-shielding sheets 5 are respectively arranged as arc-shaped sheets and are arranged around the inside of the fixed cover 1, which is convenient for subsequent adjustment of the irradiation device 15. The first elastic metal ring 3 and the second elastic metal ring 6 can respectively ensure the stability of the surrounding arrangement of the multiple first light-shielding sheets 4 and the second light-shielding sheets 5. The connecting seat 2 can stably fix the first elastic metal ring 3 inside the fixed cover 1. Subsequently, pulling one of the connecting blocks 7 can drive the elastic metal ring 8 to expand outward, and the connection parts of the multiple first light-shielding sheets 4 and the multiple second light-shielding sheets 5 with the connecting block 7 can expand outward, so that the irradiation range of the irradiation device can be expanded.

The multiple guide blocks 9 slide along the inner wall of the guide groove, which can ensure the tight connection between the multiple first light-shielding sheets 4 and the multiple second light-shielding sheets during the adjustment movement.

[0029] To make it more convenient to adjust the connecting block 7, as Figures 1-4 shown, a hinge seat 10 is fixedly connected to the side wall of one of the connecting blocks 7.
