Be equipped with stop gear between roating seat 45 and the mounting bracket 52, stop gear is including setting up spacing slide rail 56 on roating seat 45, the tip of mounting bracket 52 is equipped with along the gliding stopper 57 of spacing slide rail 56.

An inclination fine adjustment mechanism 58 is arranged between the telescopic cylinder 37 and the positioning cylinder 20.

The inclined fine adjustment mechanism 58 comprises a fourth threaded cylinder 59 which is rotatably hinged with the telescopic cylinder 37, the positioning cylinder 20 is hinged with the rotary sliding block 10 through a rotating hinge, a fine adjustment screw rod 60 is arranged in the fourth threaded cylinder 59, one end of the fine adjustment screw rod 60 is hinged with the outer wall of the positioning cylinder 20, the sputum excretion tube can be subjected to fine inclined adjustment, and the sputum suction position of the sputum excretion tube can be conveniently changed and adjusted.

The working principle is as follows: the invention positions the sputum discharging pipe extending into the body of the severe patient by arranging the sputum discharging pipe positioning mechanism 7, fixes the sputum discharging pipe at a specific angle without manually holding the sputum discharging pipe for positioning, thereby effectively avoiding that medical staff positions the sputum discharging pipe at a certain angle and posture for a long time, the generated ache feels that hand shake occurs, the sputum discharging pipe cannot have good positioning function, the sputum discharging pipe is misplaced and is easy to collide with the trachea and other parts of the severe patient to cause injury and aggravate the disease, the rotation angle of the sputum discharging pipe can be micro-adjusted by arranging the rotation micro-adjusting mechanism 12 and the propulsion micro-adjusting mechanism 13, and the sputum discharging pipe accurately and slowly enters the body of the severe patient under the propulsion function of the micro-adjusting propulsion mechanism 13 to suck the sputum in the body of the severe patient by utilizing the sputum discharging pipe, and the sputum discharging pipe can extend to the depth and the position angle for micro-adjustment, the sputum in the body of the patient with the severe symptoms can be conveniently sucked in multiple directions, so that the sputum excretion effect is improved, and the flexibility is strong.
