The flat piston rod 105 and the bottom of the C-shaped airtight tube 104 are fixedly connected with an inverted T-shaped airtight tube 106, and both ends of the inverted T-shaped airtight tube 106 are fixedly connected with horizontal driving piston rods 107 fixedly connected with the C-shaped sliding seat 43, that is, when the symmetrical C-shaped sliding seats 43 are close to each other to clamp the patient's head, the symmetrical horizontal driving piston rods 107 inflate the inverted T-shaped airtight tube 106 and the C-shaped airtight tube 104, so that the symmetrical self-resetting horizontal piston rods 105 accumulate force to be reset;

[0051] The associated part B200 includes a vertical sliding groove 201 provided on the back of the cheek clamping seat 30, the vertical sliding groove 201 is slidably connected to a vertical sliding seat 202, and the side of the vertical sliding seat 202 is evenly fixedly connected to a self-resetting sawtooth B203 capable of deflecting inwards, and the associated part B200 also includes an opening 204 provided in the adjustable bottom plate 11 and an L-shaped airtight tube 205 fixedly connected to the C-shaped sliding seat 43, and the bottom of the vertical sliding seat 202 is fixedly connected to a self-resetting sawtooth B203 passing through the opening 204. 04 and extends to the self-resetting vertical piston rod 206 at one end of the L-shaped airtight tube 205, and the other end of the L-shaped airtight tube 205 is provided with a horizontal fixed piston rod 207 fixedly extending to the bottom of the adjustable bottom plate 11, that is, when the symmetrical C-shaped sliding seats 43 are close to each other to clamp the patient's head, the symmetrical L-shaped airtight tubes 205 are close to each other so that the horizontal fixed piston rod 207 inflates the inside of the L-shaped airtight tube 205, so that the symmetrical self-resetting vertical piston rod 206 accumulates force to be reset;

[0052] The outside of the C-type airtight tube 104 and the L-type airtight tube 205 are both axially symmetrically provided with ventilation holes 121, and the outside of the C-type airtight tube 104 and the L-type airtight tube 205 are both provided with one-way suction pipes 122. The ventilation holes 121 and the one-way suction pipes 122 are respectively located on both sides of the self-resetting horizontal piston rod 105 or the self-resetting vertical piston rod 206. When the self-resetting horizontal piston rod 105 or the self-resetting vertical piston rod 206 moves to the outside of the ventilation holes 121, the excess gas inside the C-type airtight tube 104 or the L-type airtight tube 205 is discharged through the ventilation holes 121.

[0053] The working principle of this embodiment is as follows: when the patient's head needs to be supported and fixed for an ophthalmic examination, the patient can place the mandible on the mandible support roller 60 in the mandible support seat 20, so that the mandible support roller 60 supports the patient's mandible, and then the adjusting rotating wheel 42 can be rotated to rotate the bidirectional adjustment screw rod 41 and drive the C-shaped sliding seats 43 on both sides to slide in a direction close to each other, until the cheek clamping rollers 70 in the cheek clamping seats 30 on both sides clamp and fix the head supported on the mandible support seat 20;

[0054] In the process that the C-shaped sliding seats 43 on both sides drive the cheek clamping rollers 70 on both sides to slide towards each other, the horizontal driving piston rod 107 fixedly connected to the C-shaped sliding seats 43 on both sides will inflate the inside of the inverted T-shaped airtight tube 106 and the C-shaped airtight tube 104, so that the self-resetting horizontal piston rods 105 on both sides are squeezed outward and the vent holes 121 are exposed. The squeezed self-resetting horizontal piston rods 105 drive the horizontal sliding seats 102 to slide, so that the horizontal sliding seats 102 on both sides are close to each other, and the self-resetting sawtooth A103 that moves with the horizontal sliding seat 102 is driven by the connecting gear The damping contact of 92 will deflect outward (until the self-resetting sawtooth A103 is disengaged from the connecting gear 92), and then the excess gas inside the inverted T-shaped airtight tube 106 and the C-shaped airtight tube 104 will be discharged through the vent 121, and the symmetrical self-resetting horizontal piston rod 105 will accumulate force to wait for resetting. After the cheek clamping rollers 70 on both sides clamp and fix the patient's head, the horizontal driving piston rod 107 is fixed in position and no longer inflates the inside of the inverted T-shaped airtight tube 106 and the C-shaped airtight tube 104. The self-resetting horizontal piston rod 105 with accumulated force will reset a short distance to block the vent 121.

[0055] At the same time, the symmetrical L-shaped airtight tubes 205 fixedly connected to the C-shaped sliding seats 43 on both sides are close to each other so that the horizontal fixed piston rod 207 inflates the inside of the L-shaped airtight tube 205, so that the self-resetting vertical piston rods 206 on both sides are squeezed upward and the vent holes 121 are exposed. The squeezed self-resetting vertical piston rods 206 drive the vertical sliding seat 202 to slide, and the self-resetting saw teeth B203 that move with the vertical sliding seat 202 are damped by the connecting gear 92 and deflected inward (until The self-resetting sawtooth B203 is disengaged from the connecting gear 92), and then the excess gas inside the L-shaped airtight tube 205 is discharged through the vent 121, and the self-resetting vertical piston rods 206 on both sides are charged to be reset. After the cheek clamping rollers 70 on both sides clamp and fix the patient's head, the position of the L-shaped airtight tube 205 is fixed and the horizontal fixed piston rod 207 is no longer inflated, and the charged self-resetting vertical piston rod 206 will reset a short distance to block the vent 121;

[0056] When it is necessary to release the support and fixing effect of the mandibular support roller 60 and the cheek clamping seats 30 on the patient's head, the adjusting rotating wheel 42 can be rotated to rotate the bidirectional adjustment screw 41 and drive the C-shaped sliding seats 43 on both sides to slide in the direction away from each other, so that the cheek clamping rollers 70 in the cheek clamping seats 30 on both sides no longer clamp and fix the head supported on the mandibular support seat 20 and reset;

[0057] When the C-shaped sliding seats 43 on both sides drive the cheek clamping rollers 70 on both sides to slide away from each other, the horizontal driving piston rod 107 fixedly connected to the C-shaped sliding seats 43 on both sides will evacuate the inside of the inverted T-shaped airtight tube 106 and the C-shaped airtight tube 104, so that the outside air enters through the vent hole 121. Similarly, the symmetrical L-shaped airtight tubes 205 fixedly connected to the C-shaped sliding seats 43 on both sides move away from each other, so that the horizontal fixed piston rod 207 evacuates the inside of the L-shaped airtight tube 205, so that the outside air enters through the vent hole 121.

[0058] When the cheek clamping rollers 70 on both sides no longer clamp and fix the patient's head, the self-resetting vertical piston rods 206 with stored force on both sides will reset and drive the vertical sliding seats 202 on both sides to slide down and block the vents 121, and the self-resetting sawtooth B203 following the movement of the vertical sliding seat 202 will drive the connecting gear 92 to rotate, so that the cheek clamping rollers 70 rotate to change sides. Similarly, when the patient's head leaves the mandibular support roller 60, the self-resetting horizontal piston rods 105 with stored force on both sides will reset and drive the horizontal sliding seats 102 on both sides to move away from each other and block the vents 121, and the self-resetting sawtooth A103 following the movement of the horizontal sliding seat 102 will drive the connecting gear 92 to rotate, so that the mandibular support roller 60 rotates to change sides.

[0059] When the mandibular support roller 60 and the cheek clamping roller 70 rotate and change their surfaces, the dust and dandruff adhering to their surfaces are first cleaned by the cleaning dry sponge block 81, and then the surfaces are disinfected by the disinfecting wet sponge block 82, thereby achieving the purpose of autonomous routine cleaning and disinfection.

[0060] The main difference between this embodiment and the prior art is that: when the rotating wheel 42 is rotated to achieve the clamping and fixing effect, the symmetrical self-resetting horizontal piston rod 105 and the self-resetting vertical piston rod 206 can store force to wait for resetting, and when the rotating wheel 42 is rotated in the opposite direction to release the clamping and fixing effect, the self-resetting vertical piston rod 206 and the self-resetting horizontal piston rod 105 will be reset and drive the mandibular support roller 60 and the side cheek clamping roller 70 to rotate and change the surface. During the rotation and changing process, the mandibular support roller 60 and the side cheek clamping roller 70 will first clean the dust and dandruff adhered to their surfaces through the cleaning dry sponge block 81, and then disinfect their surfaces through the disinfecting wet sponge block 82, so that the purpose of autonomous routine cleaning and disinfection can be achieved.

[0063] The connecting member 90 also includes a fixed cylinder 93 and a bearing 94 evenly embedded in the top of the front plate 232 and the top of the back plate 233. The fixed cylinder 93 is rotatably connected to a rotating cylinder 95 inside. A cross assembly groove 96 is provided inside the rotating cylinder 95. One end of the rotating shaft 91 is fixedly connected to the inner ring of the bearing 94. The other end of the rotating shaft 91 is fixedly connected to a cross assembly block 97 located inside the cross assembly groove 96. After the middle seat 231, the front plate 232 and the back plate 233 are installed, the rotation of the connecting gear 92 can drive the cross assembly block 97 to rotate inside the cross assembly groove 96 through the rotating shaft 91, so as to ensure the stability of the mandibular support roller 60 or the cheek clamping roller 70 during the rotation process.

[0064] The self-resetting horizontal piston rod 105 and the self-resetting vertical piston rod 206 are both composed of a connecting rod 123 and a piston rod 124. The end of the connecting rod 123 away from the piston rod 124 is fixedly connected to the outer side of the horizontal sliding seat 102 or the bottom side of the vertical sliding seat 202. The piston rod 124 is arranged inside and outside the C-type airtight tube 104 or the L-type airtight tube 205. The end of the connecting rod 123 close to the piston rod 124 is fixedly connected with an external threaded section 125. The end of the piston rod 124 close to the connecting rod 123 is rotatably connected with an internal threaded sleeve 126 threadedly connected to the outside of the external threaded section 125. The connecting rod 123 can be disengaged from the piston rod 124 by rotating the internal threaded sleeve 126, so as to facilitate the disassembly of the mandibular support seat 20 and the side cheek clamping seat 30.

[0065] The working principle of this embodiment is as follows: when it is necessary to disassemble the mandibular support seat 20 and the cheek clamping seat 30 for deep cleaning and disinfection, the internal threaded sleeve 126 can be rotated first and the horizontal sliding seat 102 can be pushed inward to disengage the internal threaded sleeve 126 from the external threaded section 125, thereby disengaging the connecting rod 123 from the piston rod 124, and then disassembling the bolts between the mounting plate 234 and the adjustable bottom plate 11 to disengage the mandibular support seat 20 from the adjustable bottom plate 11, and then disassembling the bolts between the middle seat 231 and the front plate 232 to disengage the cleaning dry sponge block 81 from the mandibular support roller 60, and then disassembling the bolts between the middle seat 231 and the back plate 233 to disengage the disinfection wet sponge block 82 from the mandibular support roller 60, so that the various components of the mandibular support seat 20 can be deeply cleaned and disinfected, and the cleaning dry sponge block 81 and the disinfection wet sponge block 82 inside the mounting seat A83 and the mounting seat B84 can be replaced, and the disinfectant inside the liquid storage box 85 can be replenished;

[0066] The disassembly steps of the cheek clamps 30 on both sides are similar, that is, the detachable mandibular support seat 20 and the cheek clamps 30 on both sides and their components can facilitate medical staff to perform deep cleaning and disinfection thereof.

[0067] The main difference between this embodiment and the prior art is that after a certain number of routine cleaning and disinfection times, the mandibular support seat 20 and the side cheek clamping seats 30 on both sides in this embodiment can be manually disassembled, including the middle seat 231, front plate 232, and back plate 233 that constitute the structure, so as to separate the cleaning dry sponge block 81 and the disinfecting wet sponge block 82 on the outside of the mandibular support roller 60 and the side cheek clamping roller 70. In this way, the various components of the mandibular support seat 20 and the side cheek clamping seat 30 can be deeply cleaned and disinfected, and the cleaning dry sponge block 81 and the disinfecting wet sponge block 82 can be replaced, and the disinfectant in the liquid storage box 85 can be replenished.
