A T-shaped column 708 is slidably installed on the inner wall of the sliding hole 707, and a spring 2 709 is sleeved on the outer wall of the T-shaped column 708. A resistance block 710 is installed on the bottom side of the T-shaped column 708, and the resistance block 710 contacts the fixed block 703. By pulling the T-shaped column 708, the T-shaped column 708 slides in the sliding hole 707. Under the cooperation of the rectangular block 706 and the resistance block 710, the spring 2 709 is compressed to release the fixation of the fixed block 703. Otherwise, the sliding block 702 is slidably fixed, thereby realizing the limitation of the sliding of the sliding block 702 to prevent it from sliding when not in use and affecting the line of sight of medical staff.

[0031] Reference Figure 4-5 In the utility model, the lower side of the resistance block 710 is set with a rounded edge. The lower side of the resistance block 710 is set with an arc surface and coated with a smooth layer, so that the sliding block 702 can be directly slid and resisted without pulling the T-shaped column 708, thereby improving practicality.

[0032] In summary, when in use, according to the size of the medical staff's head circumference, the shielding hood 1 is brought to the head position through the adjustment mechanism 6, and then the size is adjusted, and the adjusted size is limited by the limiting component of the adjustment mechanism 6 to prevent it from falling off and shifting when worn. The connecting rod 2 is a supporting component for the connecting block 3, the protective end 4 and the protective pad 5, and the protective pad 5 protects the front end of the head to improve wearing comfort. When used in cold winter weather, due to the temperature difference between indoors and outdoors or when exhaling, fog will be generated on the shielding hood 1, obstructing the medical staff's vision, or the patient's sneezing droplets will stick to the surface of the shielding hood 1. Since it is inconvenient to wipe and clean the fog or dirt on the shielding hood 1 while wearing gloves, the interference component of the cleaning mechanism 7 can be released and fixed, and then the shielding hood 1 can be cleaned. The inner and outer sides of the shield 1 are cleaned, and the setting of the interference component prevents the cleaning component in the cleaning mechanism 7 from being offset when not cleaned, thereby affecting the field of vision of the medical staff.

By pulling the adjustment column 608 to slide in the circular hole 607, the limit ring 609 and the adjustment frame 605 are driven to cooperate, compressing the spring 1 610, so that the adjustment column 608 is separated from the circular groove and raised, and then the connecting sub-end 602 is connected. The connecting sub-end 602 is slidably inserted into the adjustment frame 605, and the connecting sub-end 602 is contracted according to the head circumference of the medical staff. When it fits the head, the adjusting column 608 is released, and the adjusting column 608 is driven to slide from the adjusting hole 603 into the circular groove under the reset elastic force of the spring 1 610, so as to limit the connecting sub-end 602. The connecting sub-end 602 and the connecting female end 604 are rotated on the shaft column 601 to adjust the angle of the shielding cover 1, so as to adjust the wearing according to the head circumference of the medical staff. The buffer pad 606 is set to a foam material, so as to improve the wearing comfort of the medical staff. The sliding fixed block 703 is driven to slide in the sliding groove 701 on the shielding cover 1, and the cleaning rod 704 is inside and outside the shielding cover 1. Wipe both sides to clear the mist and dirt. When not in use, the bolt 711 can be turned to disengage the threaded hole 712 and the threaded groove, so that the cleaning rod 704 can be disassembled and cleaned. By pulling the T-shaped column 708, the T-shaped column 708 slides in the sliding hole 707. Under the cooperation of the rectangular block 706 and the resistance block 710, the spring 2 709 is compressed to release the fixation of the fixed block 703. Otherwise, the sliding block 702 is slid and fixed, thereby limiting the sliding of the sliding block 702 to prevent it from sliding when not in use and affecting the line of sight of medical staff.
