Secondly, by setting a hand-held rotating ring 201, the rotation of the rotating ring 201 drives the guide block 202 to rotate in the inner cavity of the guide rail 203. , to guide and limit the rotating ring 201 in the rotating state, to prevent the rotating ring 201 from falling off and deflecting during the rotation process, the rotation of the rotating ring 201 drives the teeth 210 to move, and drives the gear 1 204 to rotate under the action of meshing, and the rotation of the gear 1 204 drives the gear 2 208 to rotate under the action of meshing, and the rotation of the gear 208 drives the screw 206 to rotate in the inner cavity of the support block 105, and then drives the screw sleeve 205 to move outward under the action of the reverse thread. , the movement of the screw sleeve 205 drives the telescopic rod 102 to move, and the movement of the telescopic rod 102 drives the hook needle 103 to move outward, thereby adjusting the position of the hook needle 103, and then achieving the effect of extending and shortening the hook needle 103. Finally, when the movement of the telescopic rod 102 drives the connecting rod 106 to move outward, the movement of the connecting rod 106 drives the slider 104 to move, thereby guiding the telescopic rod 102 in the moving state, preventing the telescopic rod 102 from offsetting during the movement process, and further adjusting the position of the hook needle 103, so as to penetrate into different parts of the oral cavity, such as periodontal pockets, subgingival areas and other difficult-to-reach areas, to accurately measure their depth and condition, and enable the hook needle 103 to be more accurately positioned to the area to be examined, reducing misdiagnosis or missed diagnosis caused by inaccurate position, and different patients have different oral structures and sensitivities. Adjusting the position of the hook needle 103 can be adjusted according to the patient's specific situation to provide a more personalized examination experience.
