The embodiment 2 is the optimal embodiment as can be seen from the comparative analysis of the test results in the table above, by adopting the above technical scheme, the prepared wear-resistant coating can form a better coating after spraying, cracks are not easily generated, the film forming effect is better, the prepared wear-resistant layer has better performances of corrosion resistance, wear resistance, skid resistance and aging resistance, the adhesion is better, the wear-resistant layer is not easy to fall off, and the performances of corrosion resistance, wear resistance, skid resistance and aging resistance of the driven bevel gear 704 and the driving bevel gear 705 can be effectively improved, so that the otology child examination anti-movement auxiliary fixing frame has longer service life.

The working principle is as follows: the anti-moving auxiliary fixing frame for examining children in otology is characterized in that a designed height adjusting mechanism 7 consists of a matching groove 706, a fixed cover plate 707, a square sleeve 701, a matching seat 703, a threaded rod 702, a driven bevel gear 704, a connecting rod 709, a crank 708 and a driving bevel gear 705, the crank 708 can be used for driving the driving bevel gear 705 to rotate, the driving bevel gear 705 can be used for driving the driven bevel gear 704 to rotate, the driven bevel gear 704 can be used for driving the threaded rod 702 to rotate, since the square sleeve 701 is vertically and slidably arranged inside the chair back 2, the square sleeve cannot rotate, thereby enabling the square bushing 701 to move linearly up and down along the threaded rod 702, so that the height of the head fixing mechanism 6 is adjusted by the up-and-down linear movement of the square bushing 701, the anti-moving auxiliary fixing frame for the otology infant examination is suitable for fixing infants with different heights, so that the practicability of the anti-moving auxiliary fixing frame for the otology infant examination is better;

the designed angle adjusting mechanism 5 is composed of a U-shaped fixed seat 501, a connecting seat 504, a connecting arm 505 and a first locking bolt 503, and can adjust the inclination angle of the head fixing mechanism 6 so as to meet the requirement that the head of an infant can still be firmly and stably fixed by the head fixing mechanism 6 in a state of inclining at a certain angle, so that the otology infant examination movement-prevention auxiliary fixed frame can meet the use requirement that the head of the infant needs to incline at a certain angle when a doctor examines the auditory canal of the infant;

the designed head fixing mechanism 6 consists of a fixing seat 601, an annular air bag 602, an inflation tube 603, a pressurizing ball 604, a first one-way valve 605, a second one-way valve 606, an exhaust tube 608 and an exhaust valve 607, and the head of the infant can be fixed by the expansion of the annular air bag 602, so that the tightness degree of the head fixing mechanism 6 can be adjusted, and the head fixing mechanism can be suitable for fixing the heads of infants with different head sizes;

the cushion block 805 and the seat cushion 9 can play a good role in protecting the infant, and the comfort of the anti-moving auxiliary fixing frame for the examination of the infant in the otology department can be effectively improved.

The using method comprises the following steps: when the infant ear canal examination device is used, an infant sits on the upper portion of the seat cushion 9, the crank 708 is swung to adjust the height of the head fixing mechanism 6 according to the height of the infant, then the inclination angle of the head fixing mechanism 6 is adjusted through the angle adjusting mechanism 5 according to the inclination angle of the head of the infant when a doctor examines the ear canal of the infant, then the two groups of hand fixing mechanisms 8 are used for fixing the two hands of the infant, the head of the infant extends into the annular air bag 602, the annular air bag 602 is ensured to be located above the ear of the infant, the pressurizing ball 604 is continuously pressed and released to inflate the inside of the annular air bag 602, the head of the infant is fixed through the expansion of the annular air bag 602, after the doctor examines the ear canal of the infant, the air inside the annular air bag 602 is exhausted through the exhaust pipe 608 through the exhaust valve 607, and the two.

The parts not involved in the present invention are the same as or can be implemented by the prior art. The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
