Middle = !! The moving device 241 is designed as a ratchet, so when the second latch 24 ^ is rotated and the clothes set 241 is engaged, the second rotating device 241 can only be used. The 3-way rotation, the user can pull the _ pillow „And adjusting m η = The headrest 11 *" Figure 7-2 "can be adjusted to the position shown in" Figure 7_3 "-but because of the design of this ratchet, the user cannot A ^; the elevation angle of the moving pillow 11, so if the user wants to change the headrest ui state, please refer to "Figure 5-3" and "Figure M angle; press the left side of the button cover 210, When the second press is known as 244, the second neck = ugly = 8 The first neck 2443 of M275830 is fitted down to the second bottom 2444, so that the slope of the first part 2 is engaged with the second convex part 2441, in this way, the younger brother behind Jane-Jan 2433 moves, and the material lion returns to the "Figure 7_2". Press the second button 244, and then press the second button to return to the second one. Two sets of rings 243 Follow the slope of the second necked portion 2442 and then engage two: "3", then the second latch 2433 engages with the second rotating device 241, and the elevation angle of the headrest 11 is fixed. R It is better here In the embodiment, during the process of the second braking mechanism 2 'the elevation angle of the headrest 11 can only increase without sudden fall', so that the patient is vulnerable to injury; however, familiar with this technology 。 [Rotating position 23] and the second rotating device ice can be: the ratchet 'can achieve the purpose of adjusting the height of the headrest u and the elevation angle. Heart palpitations-In addition, because the upper casing 21 has a button cover 21〇 design , The first "and the second press red 244 cover at the same time, so in addition to pressing the right or left side of the red to make the height of the first contact mechanism m = 11 and the elevation angle. As mentioned above, the combination of the first brake mechanism 23 and the second brake mechanism 24 for the headrest adjusting machine of the dental chair of the new type of dental diagnosis chair H = can be achieved by the simple pillow adjusting mechanism 2G during the diagnosis and treatment Single = the height and elevation angle of Kexi teacher pillow 11 to meet the needs of diagnosis and treatment.
