[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 2. The present invention is connected to the fixing seat by setting an adjusting mechanism 1, and a driving mechanism and an adjusting mechanism 2 are set on the adjusting mechanism 1. When using the device to fix and adjust the patient's head, the user can guide the patient to place the head on the placement plate, and use the neck pillow to support the neck, while making the top of the patient's head fit with the inner side of the top plate. Then the user takes the adjusting mechanism 2 and moves to insert the insertion rod into the insertion hole so that the support plate corresponds to the patient's lower jaw. At this time, the user can rotate the connecting shaft 1 on one side and use the transmission of the pulley 1 to drive the connecting shaft 1 on the other side to rotate synchronously. When the connecting shaft 1 rotates, the meshing transmission of the bevel gear 1 and the bevel gear 2 drives the two screw rods 2 to rotate forward. When the screw 2 rotates forward, it drives the connecting plate 1 and the adjusting mechanism 2 to move to the right as a whole through the connection with the threaded hole 2. When the inner side of the support plate moves to fit closely with the patient's chin, the connecting shaft 1 is stopped, so that the patient's head is fixed and coordinated with the first aid operation by using the cooperation between the support plate and the top plate. In addition, the fixing method of the device will not be loose during the first aid process to avoid affecting the doctor's first aid operation.

[0022] 3. The present invention is connected with the driving mechanism by setting the adjusting mechanism 1 and the adjusting mechanism 2. After the patient's head is fixed by the driving mechanism, when the patient's head needs to be adjusted to a backward tilted posture, the user can control the electric push rod to retract through the controller, and use the sliding sleeve, the sliding rod 2 and the fixing frame 3 to drive the placement plate to tilt backward along the support rod, thereby using the tilt of the placement plate to drive the patient's head to tilt backward, thereby facilitating emergency personnel to perform emergency operations such as opening the airway of the patient. At the same time, during the emergency treatment of the patient, the user can rotate the screw rod 3 on one side and use the pulley 2, the pulley 3, the connecting shaft 2, the gear 1 and the gear 2 to drive the screw rod 3 on the other side to rotate in opposite directions. When the screw rods 3 on both sides rotate in opposite directions, the two nuts are driven to move in opposite directions. At this time, the nuts drive the support plate to tilt through the connecting frame, the sliding rod 3 and the connecting plate 3, thereby using the tilting rotation of the support plate to drive the patient's head to one side, and then after the patient's airway is opened, the patient's head is placed sideways to maintain the patient's normal breathing, and then the adjusting mechanism 1 and the adjusting mechanism 2 are used to adjust the patient's head posture to assist emergency personnel in performing emergency operations, thereby further increasing the functionality of the device.

[0023] The user can then pull the rotatable plate upward to rotate it 180 degrees along the rotation axis 2. At this time, the rotatable plate rotates to the top of the fixed seat so that the adjusting mechanism 1, the adjusting mechanism 2 and the driving mechanism are all rotated to overlap with the fixed seat, thereby further reducing the overall volume of the device and making it easier for the user to carry and store the device.

Therefore, when the fixing mechanisms 6 on both sides are used, the user only needs to operate the fixing mechanism 6 on one side to realize the synchronous operation of the fixing mechanism 6 on the other side, thereby reducing the user's operating steps and improving the convenience of operation of the device. A through hole 1 63 and a through hole 2 64 are opened on the side of the mounting plate 61, and the inner side surfaces of the through hole 1 63 and the through hole 2 64 are respectively slidably connected to the outer surfaces of the connecting tube 1 3 and the connecting tube 2 4.

[0045] The operating steps of the present invention are:

[0046] When using the device, the user can pull the two fixing mechanisms 6 to move to the two sides of the fixing seat 1. At this time, the user can rotate the worm 620 on one side to rotate forward and use the connecting rod 613, the limit plate 610 and the connecting tube 4 to drive the worm 620 on the other side to rotate forward synchronously. When the worm 620 rotates forward, it drives the rotating shaft 1 614 and the splint 67 on both sides to rotate in the opposite direction through the meshing transmission with the worm wheel 616. At this time, the splint 67 extends out from the through slot 1 65. When the splint 67 rotates upward to a vertical state, the worm 620 is stopped. Then the fixing seat 1 and the mounting plate 61 are placed on the patient's shoulders so that the splints 67 on both sides are respectively located on both sides of the patient's shoulders. At this time, the user can rotate the screw 1 69 on one side to rotate forward and use the limit plate 1 68 and the connecting tube 3 to drive the screw 1 69 on the other side to rotate forward. When the screw 1 69 rotates forward, it drives the sliding plates 612 and the splint 67 on both sides to approach each other through the threaded connection with the threaded hole 1 611. When the two splints 67 are both close to the patient's shoulders When the fit is tight, stop rotating the screw rod 69. The user can guide the patient to place the head on the placement plate 75 and use the neck pillow 712 to support the neck, so that the top of the patient's head fits the inner side of the top plate 710. Then the user takes the adjustment mechanism 29 and moves to insert the insertion rod 91 into the insertion hole 89 so that the support plate 99 corresponds to the patient's lower jaw. At this time, the user can rotate the connecting shaft 84 on one side and use the transmission of the pulley 1 83 to drive the connecting shaft 1 84 on the other side to rotate synchronously. When the connecting shaft 1 84 rotates, the meshing transmission of the bevel gear 1 86 and the bevel gear 2 87 drives the two screw rods 2 82 to rotate forward. When the screw 2 82 rotates forward, it drives the connecting plate 1 88 and the adjustment mechanism 2 9 to move rightward as a whole through the connection with the threaded hole 2 810. When the inner side of the support plate 99 moves to fit tightly with the patient's chin, stop rotating the connecting shaft 84. At this time, the cooperation of the support plate 99 and the top plate 710 is used to fix the patient's head and cooperate with the emergency operation.

[0047] After the patient's head is fixed by the driving mechanism 8, when the patient's head needs to be adjusted to a backward tilting posture, the user can control the electric push rod 77 to retract through the controller 11, and utilize the sliding sleeve 78, the second sliding rod 79 and the third fixing frame 76 to drive the placement plate 75 to tilt backward along the support rod 74, thereby utilizing the tilting of the placement plate 75 to drive the patient's head to tilt backward, thereby facilitating emergency personnel to perform emergency operations such as opening the airway of the patient. At the same time, during the emergency treatment of the patient, the user can rotate the screw rod 3 96 on one side and utilize the pulley 2 98, the pulley 3 918, the connecting shaft 2 919, the gear 1 910 and the gear 2 911 to drive the screw rod 3 96 on the other side to rotate in the opposite direction. When the screw rods 3 96 on both sides rotate in the opposite direction, the two nuts 913 are driven to move in opposite directions. At this time, the nuts 913 drive the support plate 99 to tilt through the connecting frame 94, the sliding rod 3 93 and the connecting plate 3 95, thereby utilizing the tilting rotation of the support plate 99 to drive the patient's head to one side, thereby enabling the patient's head to be placed sideways after the patient's airway is opened to maintain the patient's normal breathing.

[0048] After using the device, the user can push the mounting plates 61 on both sides toward each other to move the mounting plates 61 into the placement slot 2, thereby storing and placing the mounting plates 61 in the placement slot 2 to overlap with the fixing seat 1, and then the user can pull the adjusting mechanism 2 9 to move upward as a whole to pull the insertion rod 91 out of the insertion hole 89, and store and carry the adjusting mechanism 2 9 separately, and the user can reversely rotate the worm 616 to rotate the clamping plates 67 on both sides in the opposite direction to rotate the clamping plates 67 ninety degrees to be stored in the through slot 1 65, thereby storing and hiding the fixing mechanism 6 to reduce the overall volume of the device, and then the user can pull the rotating plate 73 to rotate upward to rotate the rotating plate 73 one hundred and eighty degrees along the rotating axis 2 72, and at this time the rotating plate 73 rotates to the top of the fixing seat 1 so that the adjusting mechanism 1 7, the adjusting mechanism 2 9 and the driving mechanism 8 are all rotated to overlap with the fixing seat 1 for the convenience of the user to carry.
