In addition, the locking piece 4 is located the installation space of slip subassembly, and the locking part 42 cover of locking piece 4 is on locking boss 21, and locking boss 21 is limited locking piece 4 relative locking boss 21 circumference's position, and when the effort of other parts can't support locking piece 4, locking piece 4 still can receive locking boss 21 ascending supporting force to reduce locking piece 4 and drop and lead to the unable normal emergence of service condition of altitude mixture control device from slip subassembly, corresponding improvement altitude mixture control device's stability in use. Further, the locking boss 21 is supported between the rotating portion 41 and the rotating protrusion 411 such that a rotating space in which the rotating portion 41 rotates relative to the locking boss 21 is left in the rotating portion 41 to ensure a normal locking and unlocking operation of the locking piece 4.
Optionally, the present embodiment further provides an adjusting method configured to adjust the height adjusting device, where the adjusting step includes: the adjusting member 6 is driven to slide toward the locking portion 42, the adjusting member 6 drives the locking member 4 to rotate around the rotating protrusion 411, and the locking portion 42 is disengaged from the locking hole 12; the sliding assembly is driven to slide in the sliding groove 11 for height adjustment; the driving adjusting member 6 slides away from the locking portion 42, and the first elastic member 5 drives the locking member 4 to rotate around the rotation protrusion 411, and the locking portion 42 is inserted into the locking hole 12.
Alternatively, as shown in fig. 6 to 8, the locking boss 21 may be a rectangular boss, the rotating portion 41 includes a first inner wall 412, a second inner wall 413, a third inner wall 414, and a fourth inner wall 415 corresponding to four sidewalls of the locking boss 21, respectively, wherein the first inner wall 412 is an arc-shaped wall and faces the locking portion 42, the second inner wall 413 is disposed opposite to the first inner wall 412, and the rotating protrusion 411 is disposed on the second inner wall 413; the third inner wall 414 is connected between the first inner wall 412 and the second inner wall 413, and the fourth inner wall 415 is connected with the second inner wall 413. Here, a specific structure is that the rotating portion 41 is matched with the locking boss 21, wherein the first inner wall 412 is far away from the locking portion 42, the second inner wall 413 is close to the locking portion 42, the third inner wall 414 and the fourth inner wall 415 are respectively located at the left side and the right side of the locking boss 21, and the four inner walls together enclose a set of holes to be sleeved on the locking boss 21; the rotation protrusion 411 is disposed on the second inner wall 413, the rotation protrusion 411 abuts against the locking boss 21, the adjusting member 6 and the first elastic member 5 jointly act to drive the locking member 4 to rotate around the rotation protrusion 411, in this process, the locking boss 21 rotates in a sleeved hole surrounded by four inner walls relative to the locking member 4, wherein the rotation protrusion 411 serves as a fulcrum, the first inner wall 412 is arc-shaped (approximately the rotation protrusion 411 serves as an origin, and an arc surface obtained by taking the length of the locking boss 21 as a radius) and the rotation movement of the locking portion 42 relative to the locking boss 21 can be ensured.
