[0002] An oral viewer is a medical device used to examine the condition inside the oral cavity. It usually consists of a handheld probe and a display screen. The probe can be placed inside the oral cavity, and a high-definition camera is used to capture images of the inside of the oral cavity. The images are then transmitted to the display screen, allowing the doctor or dentist to clearly observe the condition inside the oral cavity.

[0003] Oral observation instruments are mostly used in combination of a handheld probe and a display screen connected via a wireless network or a cable. On the one hand, the user needs to adjust the position of the handheld probe to align with the patient's oral position, and on the other hand, the user needs to observe the display screen connected to the handheld probe end. The back-and-forth observation is very inconvenient. In this regard, a handheld oral observation instrument is proposed, which directly combines the display screen with the probe, so as to facilitate intuitive observation of the oral condition and timely adjustment of the probe position.

[0030] In this embodiment, the first gear 16 is fixedly connected to the rotating plate 15 , so that the first gear 16 can synchronously pull the rotor 8 to rotate relative to the stator 9 .

[0031] In this embodiment, an extension rod 18 is fixedly mounted on the outside of the rotor 8 , and the extension rod 18 is fixedly connected to the inner wall of the connecting sleeve 4 , so that the connecting sleeve 4 can be rotated relative to the barrel 2 to adjust the position of the gun head 5 .

[0032] The working principle of the above embodiment is:

[0033] When in use, the handle 1 can be directly held by hand, together with the handle 1, the barrel 2 and the gun head 5, and the patient's oral cavity can be photographed through the camera lens 6 at the end of the gun head 5, and the oral condition can be visually observed through the display screen 3 at the end of the barrel 2. At the same time, the micro motor 12 can be controlled so that the micro motor 12 drives the second gear 17 on the output end to rotate, and the second gear 17 drives the first gear 16 to rotate through tooth meshing when rotating. The first gear 16 drives the fixedly connected rotating dish 15 when rotating, so that the rotor 8 fixedly connected to the rotating dish 15 rotates relative to the stator 9. At this time, the rotor 8 drives the connecting sleeve 4 to rotate relative to the barrel 2 through the externally fixed extension rod 18, thereby adjusting the direction of the gun head 5 without causing confusion of the wires.
