An adjusting slide rod 13 is slidably provided, and an adjusting rod 14 is fixedly provided on the adjusting slide rod 13. An inclined groove 15 that cooperates with the adjusting rod 14 is provided on the extrusion block 12. A plurality of extrusion grooves 16 are provided axially on the support rod 4. An adjusting sleeve 17 is threadedly connected to the outer circumference of the support sleeve 10. A sliding ring 18 is rotatably provided on the adjusting sleeve 17. The sliding ring 18 is fixedly connected to the adjusting rod 14. An air-permeable layer 29 is provided below the water-absorbing layer 9. An air-permeable hole 30 is provided on the air-permeable layer 29. An air-permeable groove 31 that cooperates with the air-permeable hole 30 is provided on the support plate 5.

[0030] In this embodiment, during anesthesia, a shoulder cover 1 is placed on the patient's shoulder, and a support frame 3 and a support rod 4 are installed on the shoulder cover 1 via a connector 2. A support plate 5 and a protective pad 6 support the patient's chin. While adjusting the support height of the support plate 5, the position of the support rod 4 is adjusted on the support frame 3. Then, the adjusting sleeve 17 is rotated. The adjusting sleeve 17, through a sliding ring 18, drives the adjusting slide rod 13 and the adjusting rod 14 to move vertically. Through the cooperation of the adjusting rod 14 and the inclined groove 15, the squeezing block 12 moves. When the squeezing block 12 moves towards the elastic anti-slip pad 11, the elastic anti-slip pad 11 squeezes the squeezing groove 16 of the support rod 4. Through resistance friction, the support rod 4 is secured. To further adjust the height of the support rod 4 and the support plate 5, rotate the adjusting sleeve 17 in the opposite direction to move the adjusting slide rod 13 and the adjusting rod 14 in the opposite direction. Continue to adjust the height of the support rod 4. The surface layer 7 is made of soft non-woven fabric with a pearl pattern, which can increase the breathability of the patient's contact area. The surface elastic layer 8 is made of elastic breathable cotton, which has a cushioning and breathable function, improving the comfort of the protective pad 6. The absorbent layer 9 is made of super absorbent polymer material, which has the function of quickly absorbing moisture and strongly locking water, which can prevent medical medicine or other liquids from causing the patient's chin support area to become damp. The breathable holes 30 distributed on the breathable layer 29 are connected to the breathable grooves 31 on the support plate 5, which have the function of breathability and ventilation.

[0031] Please see Figure 3As one embodiment of the connector 2: the connector 2 includes a connector 19, a connector groove 20 on the connector 19, a snap-fit ​​block 21 on the connector groove 20, a snap-fit ​​groove 22 on the shoulder sleeve 1, and multiple snap-fit ​​grooves 22 on the shoulder sleeve 1. The connector 2 also includes a connector plate 23, a connector screw 24 on the connector 19, a connector nut 25 between the connector plate 23 and the connector screw 24, a connector sleeve 26 on the connector plate 23, an opening 27 on the connector sleeve 26, and the connector sleeve 26 is connected to the support frame 3 by the cooperation of bolts and nuts.

[0032] More specifically, when connecting the shoulder sleeve 1 and the support frame 3, the connecting seat 19 is fitted under the shoulder sleeve 1, so that the snap-fit ​​block 21 on the connecting groove 20 matches the snap-fit ​​groove 22 on the shoulder sleeve 1. Through the cooperation of the snap-fit ​​block 21 with different snap-fit ​​grooves 22, it is easy to adjust the position of the support plate 5 on the shoulder sleeve 1. Then, the connecting plate 23 is installed above the connecting seat 19 and the shoulder sleeve 1. The connecting plate 23 and the connecting seat 19 are connected by the connecting screw 24 and the connecting nut 25. Then, the support frame 3 is inserted into the connecting sleeve 26 and connected by the cooperation of bolts and nuts to complete the connection between the support frame 3 and the shoulder sleeve 1. The support frame 3 and the shoulder sleeve 1 do not need to be disassembled every time they are used. They can be disassembled only when adjustment or maintenance is required.

[0033] In summary, during the use or operation of the overall equipment: When performing anesthesia, shoulder sleeve 1 is placed on the patient's shoulder, and support frame 3 and support rod 4 are installed on shoulder sleeve 1 via connector 2. The patient's chin is supported by support plate 5 and protective pad 6. When adjusting the support height of support plate 5, the position of support rod 4 is adjusted on support frame 3. Then, adjusting sleeve 17 is rotated. Adjusting sleeve 17, through sliding ring 18, drives adjusting slide rod 13 and adjusting rod 14 to move vertically. Through the cooperation of adjusting rod 14 and inclined groove 15, squeezing block 12 moves. When squeezing block 12 moves towards elastic anti-slip pad 11, elastic anti-slip pad 11 squeezes the squeezing groove 16 of support rod 4, creating friction. The function is to fix the height of the support rod 4 and the support plate 5. For further adjustment, rotate the adjusting sleeve 17 in the opposite direction to drive the adjusting slide rod 13 and the adjusting rod 14 to move in the opposite direction. Continue to adjust the height of the support rod 4. The surface layer 7 is made of soft non-woven fabric with a pearl pattern, which can increase the breathability of the patient's contact area. The surface elastic layer 8 is made of elastic breathable cotton, which has a cushioning and breathable function and improves the comfort of the protective pad 6. The absorbent layer 9 is made of super absorbent polymer material, which has the function of fast moisture absorption and strong water locking, which can prevent medical medicine or other liquids from causing the patient's chin support to be damp. The breathable holes 30 distributed on the breathable layer 29 are connected to the breathable grooves 31 on the support plate 5, which have the function of breathability and ventilation.

[0034] When connecting the shoulder sleeve 1 and the support frame 3, the connecting seat 19 is fitted under the shoulder sleeve 1 so that the snap-fit ​​block 21 on the connecting groove 20 matches the snap-fit ​​groove 22 on the shoulder sleeve 1. The position of the support plate 5 on the shoulder sleeve 1 is easily adjusted by the cooperation of the snap-fit ​​block 21 with different snap-fit ​​grooves 22. Then, the connecting plate 23 is installed above the connecting seat 19 and the shoulder sleeve 1. The connecting plate 23 and the connecting seat 19 are connected by the connecting screw 24 and the connecting nut 25. Then, the support frame 3 is inserted into the connecting sleeve 26 and connected by the cooperation of bolts and nuts to complete the connection between the support frame 3 and the shoulder sleeve 1. The support frame 3 and the shoulder sleeve 1 do not need to be disassembled every time they are used. They can be disassembled only when adjustment or maintenance is required.
