[0010] A further beneficial effect of adopting the above method is that the adjustment is made more convenient and quicker.

[0011] Furthermore, the adjusting arm is arc-shaped, the first adjusting groove is an arc-shaped groove arranged coaxially with the adjusting arm, an anti-sliding block is sleeved on the positioning adjusting member, the anti-sliding block is arranged on the side of the adjusting arm away from the fixed arm, and a plurality of anti-slip ribs are provided on the opposite surfaces of the anti-sliding block and the adjusting arm, and the plurality of anti-slip ribs are distributed in an array around the center of the first adjusting groove.

[0012] The above method has the further beneficial effect of making the fixing more stable and preventing loosening after fixing by means of the engagement between the anti-slip block and the anti-slip ribs.

[0013] Furthermore, the fixing part includes a U-shaped groove arranged on the side of the adjusting arm away from the fixing arm, and both side walls of the U-shaped groove are provided with slots, one of the slots is rotatably connected to a rotating shaft on both sides, and a bolt is threadedly connected to the rotating shaft, and the bolt is rotated in the other slot through the rotating shaft.

[0014] The above method has the following further beneficial effects: the structure is simpler, the fixing effect is better, and the disassembly and installation of the eyepiece is faster.

[0015] Furthermore, a connecting tube is connected through the lower part of the guide sheath, and the connecting tube is detachably connected to the trachea.

[0016] The above method has the further beneficial effect that after use, the air pipe can be directly disassembled to facilitate next use, which is more convenient.

[0017] Furthermore, a locking nut is provided on the air pipe, and an external thread matching the locking nut is provided below the connecting pipe, and the connecting pipe and the air pipe are detachably connected via the locking nut.

[0018] The above method has the further beneficial effect of making the connection between the connecting pipe and the trachea tighter, less likely to fall off, and having a better sealing effect.

[0019] Furthermore, a control air valve is also provided on the air pipe.

[0020] A further beneficial effect of the above is that the air pressure can be adjusted according to demand. BRIEF DESCRIPTION OF THE DRAWINGS
