Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-8 The present invention provides a technical solution: a special support device and method for medical ophthalmic examination, comprising a T-shaped support column 1, an instrument fixing mechanism 2 is arranged on the lower surface of the T-shaped support column 1, an angle adjustment mechanism 3 is arranged on one side surface of the T-shaped support column 1, a head frame 4 is arranged on the upper surface of the angle adjustment mechanism 3, a rotating shaft 5 is fixedly connected to one side surface of the head frame 4, a forehead support 6 is slidably connected to one side surface of the rotating shaft 5, a sponge 7 is fixedly connected to one side surface of the forehead support 6, and a jaw support adjustment mechanism 8 is arranged on one side surface of the angle adjustment mechanism 3;

[0028] The jaw support adjustment mechanism 8 includes a jaw support adjustment knob 801, a driving gear 802, a driven threaded column 803, a jaw support chassis 804, a first jaw support bracket 805, a spring 806, a rotating connecting rod 807, a rotating barrel 808 and a second jaw support bracket 809. The jaw support adjustment knob 801 is slidably connected to one side surface of the angle adjustment mechanism 3, the driving gear 802 is fixedly connected to one side surface of the jaw support adjustment knob 801, the driving gear 802 is meshed with the driven threaded column 803, and the upper surface of the driven threaded column 803 is fixedly connected to the jaw support. The chassis 804, one side surface of the jaw support chassis 804 is slidably connected to the first jaw support bracket 805, one side surface of the first jaw support bracket 805 is slidably connected to the spring 806, one side surface of the first jaw support bracket 805 is rotatably connected to the rotating connecting rod 807, one side surface of the rotating connecting rod 807 is rotatably connected to the rotating barrel 808, one side surface of the rotating connecting rod 807 is fixedly connected to the second jaw support bracket 809, through the jaw support adjustment knob 801, the driving gear 802, the driven threaded column 803, the jaw support chassis 804, the first jaw support bracket 805 , spring 806, rotating connecting rod 807, rotating barrel 808 and second jaw support bracket 809 are arranged. When in use, through the arrangement of the jaw support adjustment mechanism, when the patient uses it, the patient presses the lower jaw on the first jaw support bracket 805, and the first jaw support bracket 805 moves downward to drive the rotating connecting rod 807 to move rightward. Due to the existence of the rotating barrel 808 and the rotating connecting rod 807 being fixedly connected with the second jaw support bracket 809, the first jaw support bracket 805 moves downward and the second jaw support bracket 809 is clamped inward, so as to achieve a correct adjustment of the patient. The device can clamp the jaws to a certain degree. When the patient stops pressing the first jaw support bracket 805, the first jaw support bracket 805 moves upward due to the action of the spring 806, and the second jaw support bracket 809 returns to its original position, thereby restoring the device. In this way, when in use, the device can be clamped according to the mandibular shape of different patients. Regardless of whether the patient has a large or small mandible, the patient can obtain appropriate support and fixation during use. This greatly improves the versatility of the device, allowing it to meet the needs of different patient groups, including children, adults, and patients with different facial features.

[0029] Furthermore, the forehead rest 6 can rotate around the rotating axis 5 at a certain angle, and the sponge 7 is arranged on one side of the forehead rest 6, which can effectively increase the patient's comfort. Through the arrangement of the forehead rest 6 and the sponge 7, the forehead rest 6 can rotate during use, which makes it possible to adjust the angle according to the different postures and needs of the patient. The forehead rest 6 can rotate, which makes it possible to adjust the angle according to the different postures and needs of the patient. It can fit the curve of the human body and reduce local pressure concentration, thereby making the patient feel more comfortable.

[0030] Furthermore, the surface of the jaw support adjustment knob 801 is provided with anti-slip threads, and the jaw support base 804 can move up and down in the vertical direction through the cooperation between the driven threaded column 803 and the driving gear 802. Through the setting of the jaw support adjustment knob 801, when in use, the anti-slip threads can increase the friction between the knob surface and the patient's fingers. When the patient needs to adjust the jaw support, no matter in a dry environment or with a small amount of sweat on the hands, the patient can hold the knob more firmly to operate.

[0031] Furthermore, the spring 806 causes the first jaw support bracket 805 to rebound after the pressure is finished. The second jaw support bracket 809 moves inward when the first jaw support bracket 805 moves downward by rotating the connecting rod 807, thereby performing a certain clamping effect on the patient. Through the setting of the spring 806, when in use, the spring 806 causes the first jaw support bracket 805 to rebound after the pressure is finished. This can automatically adjust according to the pressure applied by the patient, can adapt to different pressures and posture changes, and improve the patient's comfort.

[0032] Furthermore, a group of second jaw support brackets 809 are arranged on each side of the first jaw support bracket 805, and the rotating barrel 808 makes the sliding of the rotating connecting rod 807 on the jaw support chassis 804 smoother. Through the arrangement of the first jaw support bracket 805 and the second jaw support bracket 809, when in use, the falling of the first jaw support bracket 805 will cause the second jaw support bracket 809 to contract inward to clamp the patient's lower jaw, which is suitable for lower jaws of different widths and improves comfort.

[0033] Furthermore, the instrument fixing mechanism 2 includes a shell fixing plate 201, a rubber pad 202, a spiral push rod 203, a push plate 204 and a fixed knob 205. The lower surface of the T-shaped support column 1 is fixedly connected to the shell fixing plate 201, and the rubber pad 202 is fixedly connected to one side surface of the shell fixing plate 201. The spiral push rod 203 is slidably connected to one side surface of the shell fixing plate 201. The push plate 204 is fixedly connected to one side surface of the spiral push rod 203. The fixed knob 205 is fixedly connected to one side surface of the spiral push rod 203. 1. The rubber pad 202, the spiral push rod 203, the push plate 204 and the fixing knob 205 are arranged. When in use, the outer shell fixing plate 201 is inserted into the table edge to be fixed, and then the fixing knob 205 is rotated. Due to the existence of the spiral push rod 203, when the fixing knob 205 is rotated, the push plate 204 moves closer to the outer shell fixing plate 201 to clamp the table top, and due to the existence of the rubber pad 202, the table top will not be damaged. In this way, the mechanism can achieve clamping on different table tops, so that the mechanism can be flexibly adjusted according to the specific needs of different inspection items.

[0034] Furthermore, the upper surface of the push plate 204 is provided with a rubber pad 202 which is the same as the outer shell fixing plate 201, and the one side surface of the fixing knob 205 is provided with an anti-slip thread. Through the setting of the rubber pad 202, when in use, the rubber pad 202 set on the upper surface of the plate 204 is the same as the rubber pad on the outer shell fixing plate 201, and the rubber pad is soft in texture. When the push plate 204 contacts other components, the rubber pad 202 can play a buffering role to prevent damage to the mechanism and components.

[0035] Furthermore, the angle adjustment mechanism 3 includes an angle adjustment rod 301, an angle adjustment knob 302, a housing 303, a telescopic sleeve 304 and a fastening hoop 305. The T-shaped support column 1 runs through the angle adjustment rod 301, one side surface of the angle adjustment rod 301 is fixedly connected to the angle adjustment knob 302, one side surface of the angle adjustment rod 301 is fixedly connected to the housing 303, one side surface of the angle adjustment rod 301 is fixedly connected to the telescopic sleeve 304, one side surface of the telescopic sleeve 304 is fixedly connected to the fastening hoop 305, through the angle adjustment rod 301, the angle adjustment knob 302, the housing 303, the telescopic sleeve 304 and the fastening hoop 305 When in use, the angle adjustment knob 302 is turned, and the angle adjustment knob 302 drives the shell 303 and the telescopic sleeve 304 to rotate through the angle adjustment rod 301. Since the angle adjustment rod 301 and the T-shaped support column 1 are provided with textures, the T-shaped support column 1 and the angle adjustment rod 301 can be effectively prevented from sliding excessively, so that the two can be kept fixed within a certain angle, so that the rotation of the mechanism within a certain angle can be satisfied, and different ophthalmic examination items can be well adapted. Different ophthalmic examinations can be flexibly adjusted according to the specific needs of different examination items. A sponge 7 is also provided on the forehead support 1 to make the patient more comfortable when using it.

[0036] Furthermore, the outer side of the angle adjustment rod 301 and the inner side of the T-shaped support column 1 are provided with textures, and the outer side of the angle adjustment knob 302 is provided with anti-slip textures. Through the arrangement of the T-shaped support column 1 and the angle adjustment rod 301, when in use, the T-shaped support column 1 and the angle adjustment rod 301 can be effectively prevented from sliding excessively, so that both of them can be kept fixed within a certain angle, thereby satisfying the rotation of the mechanism within a certain angle, and being well adapted to different ophthalmic examination items. Different ophthalmic examinations can be flexibly adjusted according to the specific needs of different examination items.

[0037] Furthermore, the telescopic sleeve 304 is fixedly connected to the shell 303 through the angle adjustment rod 301, and the clamp 305 is tightened to fix the head frame 4 to the telescopic sleeve 304. The head frame 4 can be moved and fixed in the telescopic sleeve 304. Through the setting of the telescopic sleeve 304, a height adjustment function is provided during use, allowing people of different heights to find a comfortable support position, so that the patient's head can be at a comfortable height, thereby improving the use experience.

[0038] Working principle: through the setting of the jaw support adjustment mechanism, when the patient uses it, the patient presses the lower jaw on the first jaw support bracket 805, and the first jaw support bracket 805 moves downward to drive the rotating connecting rod 807 to move to the right. Due to the existence of the rotating barrel 808 and the rotating connecting rod 807 fixedly connected to the second jaw support bracket 809, the first jaw support bracket 805 moves downward and the second jaw support bracket 809 will be clamped inward to achieve a certain degree of clamping for the patient. When the patient stops pressing the first jaw support bracket 805, due to the action of the spring 806, the first jaw support bracket 805 moves upward and the second jaw support bracket 809 returns to the original position to achieve the recovery of the device. In this way, when in use, the device can be clamped according to the mandibular shape of different patients. Regardless of whether the patient has a larger or smaller mandible, they can obtain appropriate support and fixation during use. This greatly improves the versatility of the device, so that it can meet the needs of different patient groups, including children, adults and patients with different facial features. Through the setting of the angle adjustment mechanism 3, when the angle of the mechanism needs to be adjusted, the angle adjustment knob is turned. 302, the angle adjustment knob 302 drives the shell 303 and the telescopic sleeve 304 to rotate through the angle adjustment rod 301, and because the angle adjustment rod 301 and the T-shaped support column 1 are provided with textures inside, the T-shaped support column 1 and the angle adjustment rod 301 can be effectively prevented from sliding excessively, so that the two can be kept fixed within a certain angle, so that the rotation of the mechanism within a certain angle can be satisfied, and different ophthalmic examination items can be well adapted to different ophthalmic examinations. For different ophthalmic examinations, it can be flexibly adjusted according to the specific needs of different examination items. A sponge 7 is also provided on the forehead support 1 to make the patient more comfortable when using it. Through the setting of the instrument fixing mechanism 2, when in use, the shell fixing plate 201 is inserted into the edge of the table to be fixed, and then the fixing knob 205 is rotated. Due to the existence of the spiral push rod 203, when the fixing knob 205 is rotated, the push plate 204 approaches the shell fixing plate 201 to clamp the table board, and due to the existence of the rubber pad 202, the table top will not be damaged. In this way, the mechanism can be clamped on different table surfaces, so that the mechanism can be flexibly adjusted according to the specific needs of different examination items.
