[0004] During the actual ear canal inspection, the endoscope rod needs to be inserted into the ear canal for observation. During this process, the patient needs to remain still to cooperate with the doctor's inspection. However, during the inspection, there is an inevitable risk of head shaking. In addition, there are many types of patients to be inspected, and some patients cannot remain still, which will cause trouble to the inspection. If the inspection operation is still carried out, there is a risk of ear injury to the patient. In the above-mentioned public technology, there is no structure for positioning the head.

[0041] The distance adjustment mechanism 21 includes a cylinder 211 fixedly mounted on the left wall of the mounting plate 23; a connecting plate 214 fixedly mounted on the right wall of the mounting plate 23; and a connecting slide plate 212 fixedly mounted on the telescopic end of the cylinder 211, and a connecting groove 213 is provided on the bottom wall of the connecting plate 214 to be slidably connected to the connecting slide plate 212.

[0042] The detection device 4 includes a detection mechanism 1 41 disposed on the connecting slide plate 212 ; and a detection mechanism 2 42 disposed on the detection mechanism 1 41 .

[0043] The detection mechanism 41 includes a mounting tube 411 fixedly mounted on the top wall of the connecting slide plate 212; a threaded sleeve 412 rotatably mounted on the left wall of the cavity of the mounting tube 411; a reciprocating screw 413 threadedly connected to the inside of the threaded sleeve 412; a limit plate 415 fixedly mounted on the right wall of the reciprocating screw 413; two groups of limit rods 416 fixedly mounted inside the mounting tube 411, both groups of limit rods 416 are movable through the left and right walls of the limit plate 415, and both groups of limit rods 416 are slidably connected to the limit plate 415; a micro motor 414 fixedly mounted on the left wall of the mounting tube 411, and the output end of the micro motor 414 is fixedly connected to the threaded sleeve 412; and a detection component 417 arranged on the right wall of the limit plate 415.

[0044] The second detection mechanism 42 includes a detection cover 421 fixedly installed on the right side wall of the installation tube 411; a speaker 422 and a protective cotton 423 fixedly installed inside the detection cover 421, the speaker 422 is located on the inner side of the protective cotton 423, and a connecting groove 424 is opened on the left side wall of the detection cover 421, and the detection component 417 can pass through the inside of the connecting groove 424.

[0045] When the present invention is used specifically, the position of the mounting plate 23 can be changed by the electric circular guide rail 22. After the detection of one ear is completed, the mounting plate 23 can be rotated 180 degrees by the electric circular guide rail 22, and then the other ear can be detected. No manual operation is required, and it is convenient to use. The height of the movable top cover 31 can be changed by the electric linear guide rail 24, which can adapt to people of various heights and improve the scope of application. When performing the detection, the telescopic end of the cylinder 211 can be extended, and the connecting slide plate 212 can move rightward along the inside of the connecting slide groove 213. The mounting tube 411 moves with the detection cover 421 toward the ear until the right wall of the detection cover 421 fits the patient's face, and then it is driven by the micro motor 414, and its output end is rotated forward with the threaded sleeve 412, and the limit rod 416 is moved. Under the limit, the reciprocating screw 413 moves to the right with the detection component 417 and the limit plate 415, and the detection component 417 can move to the inside of the ear canal to observe the inside of the ear. After the observation, the micro motor 414 is driven to reverse the threaded sleeve 412, and the detection component 417 moves to the left until it returns to its original position. Then, the speaker 422 plays sounds of multiple frequencies to perform a hearing test on the patient. This method of performing observation and hearing tests at the same time not only facilitates the detection operation, but also increases the functionality of the device. At the same time, when performing endoscopic observation, the detection cover 421 can block the external light source to avoid cross-interference between the two groups of light sources and improve the observation effect. In addition, through mechanical propulsion, the risk of damage to the ear canal caused by shaking during hand-held inspection can be avoided.
