[0022] Embodiment 1

[0023] Referring to Figures 1-3 , as the first embodiment of the present utility model, there is provided an adjustable visual laryngoscope that is easy to operate, including: a laryngoscope body 1 and a display 2. A display 2 is provided directly above the laryngoscope body 1. A rotating rod 3 is fixedly connected to the lower surface of the display 2. The rod body of the rotating rod 3 is rotatably connected to a penetrated U-shaped connecting plate 4. Rectangular blocks 5 are provided on the lower surfaces of the U-shaped connecting plate 4, and a fixed relationship exists between the U-shaped connecting plate 4 and the rectangular blocks 5. Fixing plates 6 are provided on both sides of the rectangular blocks 5, and the fixing plates 6 are fixed on the upper surface of the laryngoscope body 1.

[0024] A round rod 7 is penetrated through the vertical plane of the fixed plate 6.

A connecting rod 9 is penetrated through the round surface of the round rod 7 away from the display 2, and a torsion rod 10 is arranged on the side of the connecting rod 9 away from the round rod 7.

[0025] During use, first manually twist the torsion rod 10. Since a cylindrical barrel is fixedly arranged on the round surface of the torsion rod 10 close to the display screen, and the cylindrical barrel slidably penetrates through the connecting rod 9, and the connecting rod 9 is fixedly connected to the round rod 7, and the rectangular block 5 is also penetrated and connected to the rod body of the round rod 7, and the round rod 7 and the rectangular block 5 are fixedly connected, so as the torsion rod 10 rotates, the round rod 7 will rotate, thereby adjusting the swing angle of the display 2. During the rotation of the round rod 7, it will drive the overall rotation of the U-shaped connecting plate 4. During the rotation of the U-shaped connecting plate 4, it will drive a pair of bevel gears 8 to rotate. When adjusting the rotation angle of the display 2, only need to twist the other torsion rod 10 first, drive the round rod 7 to rotate through the torsion rod 10. Since a pair of meshing bevel gears 8 are penetrated through the rod bodies of one of the round rods 7 and the rotating rod 3, with the drive of the pair of bevel gears 8, the rotation angle of the display 2 can be adjusted.

[0026] Embodiment 2

[0027] Referring to Figure 2 and 4 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that a bent rod 11 is arranged on the lower surface of the laryngoscope body 1, and an anti-slip layer 12 is also arranged on the handle of the laryngoscope body 1. The anti-slip layer 12 is made of rubber material, which can well ensure that there is no hand-slip phenomenon during the examination. A U-shaped plate 13 is also arranged on the vertical plane of one of the fixed plates 6, and the U-shaped plate 13 is penetrated by the round rod 7, and a rubber layer is arranged inside the hole where the U-shaped plate 13 intersects with the round rod 7. The friction between the rubber layer and the round rod 7 can well ensure that the display 2 will not collapse. A cylindrical barrel is fixedly connected to the round surface of the torsion rod 10 facing the connecting rod 9, and the connecting rod 9 is penetrated by the cylindrical barrel. A circular baffle 14 is arranged on the round surface of the cylindrical barrel inside the connecting rod 9, and an L-shaped driving rod 15 is fixedly connected to the round surface of the circular baffle 14 away from the torsion rod 10.

[0028] A cylindrical block 16 is provided inside the connecting rod 9, and a rectangular sleeve is provided through the arc surface of the cylindrical block 16, and the interior of the rectangular sleeve is slidably connected to the lifting rod 17, and a spring is also provided on the bottom surface of the rectangular sleeve, and one end of the spring is connected to the bottom surface of the lifting rod 17. A hole is also provided on the circular surface of the cylindrical block 16 close to the circular baffle 14, and a rectangular rod is also provided on the circular surface of the hole. A memory spring 18 is fixedly connected to the circular surface of the circular rod 7 away from the torsion bar 10, and one end of the memory spring 18 close to the torsion bar 10 is fixedly connected to the push plate 19. Several limit rods 20 are also provided on the rod body inside the circular rod 7, and a notch corresponding to the limit rod 20 is provided through the vertical surface of the push plate 19, and the area of the notch is the same as the area of the cross section of the limit rod 20.

[0029] Before the operation of Example 1, the torsion bar 10 is gently pushed toward the direction of the round rod 7. At this time, the L-shaped driving rod 15 will push the cylindrical block 16 into the inside of the round rod 7. Because the circular surface of the round rod 7 away from the torsion bar 10 is fixedly connected to the memory spring 18, and the end of the memory spring 18 close to the torsion bar 10 is fixedly connected to the push plate 19. At this time, the memory spring 18 will retract under the artificial thrust. After the cylindrical block 16 enters the inside of the round rod 7, because the inner diameter of the round rod 7 is larger than the inner diameter of the connecting rod 9, and a rectangular sleeve is provided through the arc surface of the cylindrical block 16, and the inside of the rectangular sleeve is slidably connected to the lifting rod 17, and a spring is also provided on the bottom surface of the rectangular sleeve, and one end of the spring is connected to the bottom surface of the lifting rod 17. After completely entering the inside of the round rod 7, the lifting rod 17 will rebound and rise, thereby pressing against the inner wall of the round rod 7. After that, the torsion bar 10 continues to push. When it cannot be pushed, twist the torsion bar 10 first, and then complete the process in Example 1.

[0030] The remaining structures are the same as those of Example 1.
