[0037] An arc groove 12 is provided on the external adjustment ring 5 , and a clamping strip 13 is provided on the external adjustment ring 5 . The clamping strip 13 is clamped and slid on the clamping groove 2 8 .
[0038] The external auditory canal expansion lighting structure 4 includes a rotational expansion structure 14 and a contact lighting device 15. The rotational expansion structure 14 is mounted on the rotation adjustment device 3, and the contact lighting device 15 is in contact with the rotational expansion structure 14; the rotational expansion structure 14 includes a bracket 16, a rack 17, a gear 18, a limit groove 19, a limit slider 20, and a deflection plate 21. The bracket 16 slides along the straight groove 10, and the bracket 16 is engaged and slid horizontally along the arc groove 12. The rack 17 is fixedly mounted on the bracket 16, the gear 18 is engaged and rotatably set on the limit plate 11, and the rack 17 and the gear 18 are meshed with each other. The limit groove 19 is fixedly set on the limit plate 11, the limit slider 20 is engaged and slides in the limit groove 19, the limit slider 20 is fixedly mounted on the rack 17, and the deflection plate 21 is fixedly mounted on the center of the gear 18.
[0039] The contact lighting device 15 includes an external auditory canal support plate 22, a conductive sheet 1 23, a conductive sheet 24 and a lamp bead chain 25. The external auditory canal support plate 22 is rotatably mounted on the rotation adjustment device 3 through a torsion spring engagement. The conductive sheet 1 23 is mounted on the external auditory canal support plate 22. The conductive sheet 2 24 is fixedly mounted on one side of the deflection plate 21. The lamp bead chain 25 is fixedly mounted on the other side of the deflection plate 21. The conductive sheet 2 24 is electrically connected to the lamp bead chain 25. The conductive sheet 1 23 is in contact with the conductive sheet 2 24.
[0040] A button battery is fixedly installed in the internal adjustment ring 6 , and the hard baffle 9 is fixedly installed between the external auditory canal support plate 22 and the deflection plate 21 .
[0041] The structure 2 close to the external auditory canal includes a universal joint connecting rod 26 and a third slot 27 . The third slot 27 is fixedly arranged on the external ear clip 1 , and the universal joint connecting rod 26 slides in the third slot 27 .
[0042] The outer ear clip 1 is fixed along the connection between the ear and the scalp.
[0043] The side walls of the external auditory canal supporting plate 22 are designed to be rounded.
[0044] When in use, the external ear clip 1 is wrapped around the connection between the patient's ear and scalp. The external ear clip 1 has its own elasticity and can fit closely to the ear root. According to the position of the external auditory canal, the curvature of the universal joint connecting rod 26 is adjusted, and the universal joint connecting rod 26 is telescopically slid in the card slot three 27. The friction resistance between the card slot three 27 and the universal joint connecting rod 26 can effectively fix the sliding distance of the universal joint connecting rod 26. The external auditory canal is S-shaped, and the internal adjustment ring 6 is rotated to make the external auditory canal support plate 22 contact with the protruding part of the external auditory canal. At this time, the front end of the external auditory canal support plate 22 is deflected toward the center of the internal adjustment ring 6. In order to make it easier to enter the deep part of the external auditory canal and reduce the obstruction of the doctor's line of sight; the internal adjustment ring 6 is squeezed by the external auditory canal and fixed relative to the external auditory canal, and the front end of the external auditory canal support plate 22 moves to the protrusion of the auditory canal, and the external adjustment ring 5 is rotated, and the external adjustment ring 5 and the internal adjustment ring 6 are relatively displaced, and the arc groove 12 is deflected and moved so that the bracket 16 is squeezed by the arc groove 12 and the bracket 16 is displaced. At the same time, the bracket 16 is restricted by the straight groove 10, so the bracket 16 slides along the straight groove 10 in the direction away from the center of the external adjustment ring 5, thereby causing the rack 17 to slide; when the rack 17 When displacement occurs, the gear 18 rotates due to the meshing connection mode. Since the deflection plate 21 is fixedly connected to the center of the circle of the gear 18, the gear 18 drives the deflection plate 21 to tilt, and the conductive sheet 2 24 is tilted and contacts the conductive sheet 1 23. Since the conductive sheet 2 24 obtains electrical energy through the button battery, after the conductive sheet 1 23 contacts the conductive sheet 2 24, the current passes through the conductive sheet 1 23 and is transmitted to the lamp bead chain 25, so that the small lamp beads on the lamp bead chain 25 light up, thereby illuminating the external auditory canal. At the same time, the deflection plate 21 tilts and squeezes the external auditory canal support plate 22. At this time, the internal adjustment ring 6 is pressed by the external auditory canal. The ear canal is squeezed and fixed, and the external auditory canal support plate 22 is engaged and deflected with the internal adjustment ring 6 as the base point. The external auditory canal support plate 22 is installed on one side of the internal adjustment ring 6, and there is no external auditory canal support plate 22 on the other side of the internal adjustment ring 6, so that the external auditory canal support plate 22 is tilted away from the external adjustment ring 5. The external auditory canal support plate 22 pushes the protruding part of the S-shaped ear canal that blocks the line of sight away from the external adjustment ring 5, and the recessed part of the external auditory canal will not be blocked by the external auditory canal support plate 22, so that the range of naked eye observation is wider, which is convenient for medical staff to observe whether there is lesion in the ear canal.

[0046] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
