[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the intraoral denture observation mechanism, through the arrangement of the lifting mechanism, the observation mechanism, the adjustment mechanism and the fixing mechanism, when in use, starts the first motor and the threaded rod rotates. According to the principle of thread transmission, the rotational motion of the threaded rod will be converted into the linear motion of the lifting plate. A limiting block is fixedly connected to the lifting block on the outer surface of the lifting plate, and a corresponding limiting groove is provided on the inner surface of the base. When the lifting plate moves up and down along the threaded rod, the limiting block will slide in the limiting groove. When the lifting plate moves up and down driven by the first motor, the connecting plate will move synchronously therewith, thereby driving the corresponding stable and reliable lifting actions of other mechanisms connected thereto, and starts the second motor to rotate the shaft. The observation head rotates in the rotation groove of the support frame, and the observation head will rotate synchronously with the rotation axis. The observation head can flexibly change the observation direction within a certain angle range, so as to realize the observation of targets in different directions and positions, expanding the scope and field of view of observation. The observation lamp can emit light to illuminate the oral cavity. The transmission line fixedly connected to the outer surface of the observation head transmits the electrical signal collected by the camera to the display panel, so that the operator can intuitively see the observed target situation. The control panel can control the entire denture observation mechanism. The stable structural support, flexible rotation function, reliable image acquisition and lighting, as well as efficient information transmission and interactive control can realize all-round, high-quality and flexibly adjustable observation of the denture. The sliding rod groove controls the sliding rod. The limiter ensures that the chin placement plate can only move in a straight line in the up and down direction to prevent it from shaking or shifting during movement. The sliding rod can also share part of the weight and external force borne by the chin placement plate. Through the contact between the sliding rod and the sliding rod groove, part of the force is transmitted to the connecting plate, thereby improving the stability and reliability of the entire adjustment mechanism, making the adjustment of the chin placement plate smoother and more accurate. The soft pad on one side of the moving plate is used to contact and fix the head of the person being tested. The moving plate slides in the T-slot through the T-block to bring the soft pad close to the head. The soft pad can increase the comfort of contact and avoid damage to the head. When the moving plate moves to the appropriate position, the card block is inserted into the card slot under the elastic force of the spring, thereby locking the position of the moving plate, which can be firmly fixed. The head is fixed to prevent it from shaking during detection or operation, ensuring the stability and accuracy of the entire process. When the fixation needs to be released, only appropriate external force needs to be applied to overcome the elastic force of the spring to disengage the card block from the slot, and then the movable plate can be moved to adjust the fixed position or release the fixation. The lifting mechanism uses the motor and threaded rod to accurately control the height, and cooperates with the limiting components to ensure stability. The observation mechanism uses the motor, rotating shaft and camera to achieve flexible observation from multiple angles with clear lighting and intuitive information transmission. The electric push rod of the adjustment mechanism allows the chin placement plate to be smoothly adjusted to adapt to the height of different users or different usage needs. The fixing mechanism can adjust the fixed head, greatly improving the clarity, accuracy and convenience of denture observation. BRIEF DESCRIPTION OF THE DRAWINGS
