Therefore, the rotating component is fixed on any suitable fixing frame, and the rotating component is used to adjust the angle of the magnetic storage tube 14, so that the doctor can insert the irradiation lamp 1 into the interior of the fixing tube 11, and use the spring to pull the clamping block 12 to press it on the top of the irradiation lamp 1, so as to fix the irradiation lamp 1 and place the irradiation lamp 1 close to the patient's eyes for irradiation, thereby relieving the doctor's fatigue caused by holding the irradiation lamp 1 for a long time and reducing the diagnostic error rate.

Since the volume of the rubber ball 32 is larger than the diameter of the sliding hole, a larger force is required to shrink the rubber ball 32 before it can be pulled out, and a larger force is used to squeeze the rubber ball 32 to be inserted into the interior of the slider 24, thereby further improving the limiting effect on the connecting rotating frame 2.

[0032] The inner wall of the slider 24 is slidably connected to a metal rod 4; the bottom end of the metal rod 4 is rotatably connected to a fixing frame 41; the bottom end of the fixing frame 41 is fixedly connected to a fixing seat 42; when the slider 24 is fixed, in order to replace the fixing frame support, the fixing seat 42 is used as a supporting chassis, and the fixing frame 41 is fixed to the top of the fixing seat 42, and the metal rod 4 is inserted into the inside of the fixing frame 41. The slider 24 is sleeved on the side wall of the metal rod 4 and slides.

At the same time, the metal rod 4 is inserted into the fixing frame 41 and rotated to adjust the irradiation direction of the irradiation lamp 1, thereby playing a role in multi-angle irradiation.

[0033] like Figures 1 to 4 As shown, two groups of oil pipes 5 are fixedly connected to the interior of the metal rod 4; multiple groups of oil overflow holes are opened in the interior of the metal rod 4, and are located at the side wall position of the oil pipe 5; multiple groups of holes are opened in the side wall of the oil pipe 5; multiple groups of guide blocks 51 are fixedly connected to the interior of the oil pipe 5, and are evenly distributed at the oil overflow holes; a sealing plug 52 is threadedly connected to the inner side wall of the metal rod 4; when the slider 24 slides on the side wall of the metal rod 4 for a long time, in order to reduce the friction between the slider 24 and the side wall of the metal rod 4, lubricating oil is injected into the interior of the metal rod 4, and the lubricating oil flows from the inside of the metal rod 4 into the interior of the oil pipe 5. Through the guidance of the guide block 51, the lubricating oil overflows into the oil overflow hole and wets the side wall of the metal rod 4, so that the slider 24 has a lubricating effect during friction. At the same time, the lubricating oil can be used to maintain the slider 24 and the metal rod 4. The sealing plug 52 is threadedly connected to the top position of the metal rod 4 to seal the lubricating oil inside the metal rod 4.

[0034] The inner wall of the metal rod 4 is fixedly connected with an elastic drawstring 6; the inner wall of the metal rod 4 is fixedly connected with a stopper 61; the bottom end of the elastic drawstring 6 is fixedly connected with a sliding block 62, and the sliding block 62 is slidably connected to the inner wall of the metal rod 4; the interior of the metal rod 4 is fixedly connected with a limiting plate 63; when a large amount of lubricating oil is stored inside the metal rod 4, in order to reduce the spillage of the lubricating oil, multiple sets of elastic drawstrings 6 are used to pull the sliding block 62 to slide on the stopper 61, and the top of the metal rod 4 is blocked with the sealing plug 52. , which plays the role of sealing the lubricating oil. When the slider 24 slides to the position of the sliding block 62, the No. 1 magnetic block 3 magnetically repels the sliding block 62, so that the sliding block 62 slides on the inner wall of the limit plate 63, and the elastic pull rope 6 is pulled and stretched, and the lubricating oil is poured into the interior of the oil pipe 5 and enters the oil overflow hole to lubricate the side walls of the slider 24 and the metal rod 4. When the slider 24 slides away from the position of the sliding block 62, the elastic pull rope 6 pulls the sliding block 62 to quickly return to its original position, and is squeezed and fitted on the stopper 61, thereby sealing the lubricating oil.

[0035] The bottom end of the sliding block 62 is fixedly connected with a matching slide plate 7; the bottom end of the matching slide plate 7 is fixedly connected with a No. 2 elastic member 71; when the sliding block 62 is magnetically repelled by the No. 1 magnetic block 3, the sliding block 62 slides on the inner wall of the limiting plate 63, and squeezes the No. 2 elastic member 71 to contract, and the matching slide plate 7 slides accordingly.

At the same time, the force of stirring the lubricating oil is used to drive the lubricating oil to be poured into the oil pipe 5 faster, thereby increasing the filling speed and amount.

[0037] A plurality of groups of sponge blocks 9 are fixedly connected to the inside of the metal rod 4; the sponge blocks 9 are located at the oil overflow hole inside the metal rod 4; when the lubricating oil is poured into the oil pipe 5, the lubricating oil flows to the sponge blocks 9 along the guide blocks 51 and is absorbed by the sponge blocks 9. Each time the slider 24 slides to the sponge block 9, part of the lubricating oil will be smeared on the inner wall of the slider 24, playing the role of lubricating oil, and the sponge block 9 is fixed at the oil overflow hole, which can play the role of blocking external impurities.

[0038] Embodiment 2

[0039] like Figure 5 As shown, compared with Example 1, another implementation of the present invention is: a counterweight block 91 is fixedly connected to the inside of the fixed seat 42; a storage groove is opened at the bottom end of the fixed seat 42; a suction cup 92 is fixedly connected to the inner wall of the fixed seat 42; when the fixed seat 42 is placed on a desktop, in order to improve the stability of the fixed seat 42, the counterweight block 91 is fixed to the inside of the fixed seat 42, which has the effect of adding weight to the fixed seat 42 and enhancing the stability of the placement of the fixed seat 42, and the suction cup 92 is adsorbed on the desktop and recessed into the storage groove, which can improve the fixing effect of the fixed seat 42 and reduce the shaking of the fixed seat 42 when it is fixed.

[0040] Working principle: When an ophthalmologist examines a patient's eyes, he usually holds a flashlight to observe the patient's eyes. However, holding the flashlight for a long time can easily increase the doctor's burden, which can easily cause hand fatigue and shaking. In severe cases, it can affect the patient's examination and treatment. Therefore, the rotating component is fixed on any suitable fixing frame, and the angle of the magnetic storage tube 14 is adjusted by the rotating component, so that the doctor can insert the flashlight 1 into the interior of the fixing tube 11, and use the spring to pull the clamping block 12 to press the top of the flashlight 1, so as to fix the flashlight 1, and place the flashlight 1 close to the appropriate position of the patient's eyes for irradiation, which can relieve the doctor's long-term The fatigue of holding the irradiation lamp 1 is reduced, and the diagnostic error rate is reduced. The irradiation lamp 1 can be slid inside the magnetic storage tube 14 by pulling the magnetic slide bar 13 and fixed by magnetic attraction, so that the irradiation lamp 1 can be extended and extended to extend the irradiation, which is convenient for the irradiation lamp 1 to adjust the irradiation effect at multiple angles; when the doctor uses the irradiation lamp 1 to irradiate and examine patients of different heights, the doctor can pull the limit pin 22 out of the slider 24, and the No. 1 elastic member 23 is stretched and stressed, and the connecting rotating frame 2 is rotated on the fixing rod 21. After adjusting the angle suitable for the patient's height, the limit pin 22 is released and inserted into the corresponding limit hole on the connecting rotating frame 2, and then inserted into the slider 24. The No. 1 elastic member 23 is stretched and stressed, and the connecting rotating frame 2 is rotated on the fixing rod 21. After adjusting the angle suitable for the patient's height, the limit pin 22 is released and inserted into the corresponding limit hole on the connecting rotating frame 2, and then inserted into the slider 24. The part 23 contracts and pulls the limit pin 22 to achieve a limiting effect, and then the magnetic slide bar 13 is pulled to adjust the length according to the patient's height, which plays a role in adapting to patients of different heights and relieving the doctor's hand fatigue; when the limit pin 22 is inserted into the interior of the slider 24 and fixed, in order to enhance the limiting effect of the connecting rotating frame 2, the two groups of No. 1 magnetic blocks 3 and No. 2 magnetic blocks 31 are used to attract each other, and the limiting effect on the connecting rotating frame 2 is enhanced by the magnetic attraction force, and the rubber ball 32 is inserted into the interior of the slider 24. Since the volume of the rubber ball 32 is larger than the diameter of the sliding hole, a larger force is required to shrink the rubber ball 32 before it can be pulled out, and a larger force is used. The rubber ball 32 can be inserted into the slider 24 only by squeezing it with a large force, thereby further improving the limiting effect on the connecting rotating frame 2. When the slider 24 is fixed, in order to replace the fixed frame support, the fixed seat 42 is used as the supporting chassis, and the fixed frame 41 is fixed on the top of the fixed seat 42, and the metal rod 4 is inserted into the fixed frame 41. The slider 24 is sleeved on the side wall of the metal rod 4 and slides. The first magnetic block 3 inside the slider 24 and the metal rod 4 are magnetically attracted to each other, so as to fix the height of the slider 24. At the same time, the metal rod 4 is inserted into the fixed frame 41 and rotated, so as to adjust the irradiation direction of the irradiation lamp 1, thereby achieving the effect of multi-angle irradiation.When the slider 24 slides on the side wall of the metal rod 4 for a long time, in order to reduce the friction between the slider 24 and the side wall of the metal rod 4, lubricating oil is injected into the metal rod 4, and the lubricating oil flows from the inside of the metal rod 4 into the inside of the oil pipe 5, and is guided by the guide block 51 so that the lubricating oil overflows into the overflow hole and wets the side wall of the metal rod 4, so that the slider 24 can play a lubricating effect during friction. At the same time, the lubricating oil can be used to maintain the slider 24 and the metal rod 4. The sealing plug 52 is threadedly connected to the top position of the metal rod 4 to seal the lubricating oil inside the metal rod 4. When a large amount of lubricating oil is stored in the metal rod 4 When the slider 24 is inside, in order to reduce the spillage of the lubricating oil, multiple sets of elastic pull ropes 6 are used to pull the sliding block 62 to slide and clamp on the stopper 61, and cooperate with the sealing plug 52 to seal the top of the metal rod 4, so as to play the role of sealing the lubricating oil. When the slider 24 slides to the position of the sliding block 62, the No. 1 magnetic block 3 magnetically repels the sliding block 62, so that the sliding block 62 slides on the inner wall of the limit plate 63, and the elastic pull rope 6 is pulled and stretched, and the lubricating oil is poured into the inside of the oil pipe 5 and enters the oil overflow hole to lubricate the side walls of the slider 24 and the metal rod 4. When the slider 24 slides away from the position of the sliding block 62, the elastic pull rope 6 pulls the sliding block 62 to quickly return to its original position and squeezes and fits on the stopper 61. It has the effect of sealing the lubricating oil; when the sliding block 62 is repelled by the magnetic force of the No. 1 magnetic block 3, the sliding block 62 slides on the inner wall of the limit plate 63, and squeezes the No. 2 elastic member 71 to contract and bear the force, and the matching slide plate 7 slides accordingly. When the No. 1 magnetic block 3 moves away from the sliding block 62, the No. 2 elastic member 71 cooperates with the elastic pull rope 6 to quickly reset the sliding block 62, and the matching slide plate 7 at the bottom of the sliding block 62 slides on the limit plate 63 accordingly, which has the effect of limiting the sliding movement of the sliding block 62; when the lubricating oil is stored in the metal rod 4 for a long time, it is easy to precipitate, so when the matching slide plate 7 is squeezed and slid, it drives the rack plate 8 to slide on the limit plate 63 The inner wall of the gear shaft 81 is meshed with the teeth on the rack plate 8, so that the gear shaft 81 rotates and drives the stirring blade 82 to stir the lubricating oil, thereby stirring the lubricating oil. At the same time, the force of stirring the lubricating oil is used to drive the lubricating oil to accelerate the filling into the oil pipe 5, thereby increasing the filling speed and amount. When the lubricating oil is filled into the oil pipe 5, the lubricating oil flows to the sponge block 9 along with the guide block 51 and is absorbed by the sponge block 9. Each time the slider 24 slides to the sponge block 9, part of the lubricating oil will be smeared on the inner wall of the slider 24, thereby playing the role of lubricating oil. Moreover, the sponge block 9 is fixed at the oil overflow hole, which can block external impurities.
