A synchronous belt 75 is installed between the two synchronous wheels 74. During the operation, blood and other liquids may adhere to the sterile cloth 6. Rotating the knob 77 drives the pressure plate 76 to rotate, thereby driving the recovery shaft 71 to rotate. Under the transmission action of the two synchronous wheels 74 and the synchronous belt 75, the recovery shaft 71 and the winding shaft 72 are in a synchronous rotation state, so that the winding drum 61 unwinds the sterile cloth 6 thereon, and the recovery drum 62 rewinds the sterile cloth 6 after use. When the used sterile cloth 6 is contaminated, the new sterile cloth 6 can be directly replaced on the side of the pillow seat 5 without making major adjustments to the gear frame and the patient. It is very convenient and quick to use, reducing the discomfort caused to the patient by replacing the sterile cloth 6.

[0036] The working principle of the present invention is: When in use, the pillow seat 5 is installed on the L-shaped connecting plate 2, and the L-shaped connecting plate 2 is adjusted to adjust the pillow seat 5, and the adjustment process of the L-shaped connecting plate 2 is as follows: Release the interference lock between the locking assembly 13 and the guide rail 11, slide the U-shaped guide bin 15 horizontally to make it slide with the guide rail 11 as the guide, and adjust the horizontal position of the L-shaped connecting plate 2. After the adjustment is completed, make the locking assembly 13 interfere with the guide rail 11 again to lock the U-shaped guide bin 15 on the guide rail 11; The contact locking assembly 2 14 and the guide rail 1 11 are locked by contact, and the lifting rod 16 is vertically slid to make it move vertically, so that the height of the L-shaped connecting plate 2 can be longitudinally adjusted. After the adjustment is completed, the locking assembly 2 14 is again in contact with the lifting rod 16 to fix the lifting rod 16 on the U-shaped guide bin 15; The contact locking assembly 110 and the rotating bar 19 are locked, so that the transverse sliding bin 114 slides transversely with the rotating bar 19 as a guide, and the transverse position of the L-shaped connecting plate 2 is further adjusted horizontally. After the adjustment is completed, the locking assembly 110 is again locked against the rotating bar 19 to fix the transverse sliding bin 114 on the rotating bar 19; Release the locking and locking between the locking component 3 17 and the rotating shaft 18, and drive the rotating shaft 18 to adjust the horizontal angle of the L-shaped connecting plate 2. After the adjustment is completed, make the locking component 3 17 contact with the rotating shaft 18 again to fix the rotating shaft 18 on the lifting rod 16; The contact locking component 5 111 and the rotating shaft 2 113 are locked by rotating the rotating shaft 2 113 to further adjust the horizontal angle of the L-shaped connecting plate 2. After the adjustment is completed, the locking component 5 111 is again in contact with the rotating shaft 2 113 to fix the rotating shaft 2 113 on the fixing sleeve 112. The screw rod 34 is driven to rotate. Under the vertical thread transmission action of the screw rod 34 and the translation block 31, the translation block 31 is driven to move downward. Under the linkage action of the push-pull bar 35, the hinge seat 1 36 and the hinge seat 3 39, the push-pull bar 35 lifts the U-shaped bin 4, so that the U-shaped bin 4 rotates counterclockwise with the hinge seat 2 37 as the rotation point, thereby adjusting the oblique state of the pillow seat 5; A sterile cloth 6 is installed between the pillow base 5 and the end of the pillow base 5 that contacts the patient's skin, and the sterile cloth 6 is used to isolate the patient from direct contact with the pillow base 5; During the operation, blood and other liquids may adhere to the sterile cloth 6. The rotating knob 77 drives the pressure plate 76 to rotate, thereby driving the recovery shaft 71 to rotate. Under the transmission action of the two synchronous wheels 74 and the synchronous belt 75, the recovery shaft 71 and the winding shaft 72 are in a synchronous rotation state, so that the winding drum 61 unwinds the sterile cloth 6 thereon, and the recovery drum 62 rewinds the used sterile cloth 6. When the used sterile cloth 6 is contaminated, a new sterile cloth 6 can be directly replaced on the side of the pillow seat 5.
