It can be inserted into the cavities of the human body and organs for direct observation, diagnosis, and treatment. The bending angle of the insertion tube of the electronic endoscope is adjusted by controlling the up and down bending through two steel wire ropes at the front end of the insertion tube. The steel wire ropes are fixed and pulled by aluminum sleeves. If the position of the aluminum sleeves is slightly off, the bending angle will not meet the requirements and cannot be adjusted, requiring rework.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes an electronic endoscope bending angle adjustment fixture, including a base plate 1, a mounting base 2 installed at the top of the base plate 1, a fixing mechanism inside the mounting base 2, a moving mechanism at one end of the mounting base 2, an aluminum sleeve groove 3 opened on one side of the top of the base plate 1, a mounting frame 4 installed at the top of the base plate 1, a cylinder 5 installed at the bottom of the mounting frame 4, and a pressure sleeve 6 installed at the bottom of the cylinder 5.

[0020] The fixing mechanism includes a placement groove 7, a positioning plate 8, a threaded hole 9, a threaded rod 10, a first rotating wheel 11, and a limiting structure. The placement groove 7 is located inside the mounting base 2. The positioning plate 8 is located inside the mounting base 2. A threaded hole 9 is provided through the top of the mounting base 2. A threaded rod 10 is provided through the threaded hole 9. The bottom end of the threaded rod 10 is rotatably connected to the top end of the positioning plate 8. The first rotating wheel 11 is installed at the top end of the threaded rod 10. In use, the electronic endoscope insertion tube is placed inside the placement groove 7. Then, the first rotating wheel 11 is rotated to drive the threaded rod 10 to rotate. Since the threaded hole 9 and the threaded rod 10 are threadedly connected, the threaded rod 10 moves inside the threaded hole 9. Then, through the mutual cooperation between the limiting hole 12 and the limiting rail 13, the threaded rod 10 can drive the positioning plate 8 to move downward. The positioning plate 8 is then used to fix the electronic endoscope insertion tube, making it more convenient and faster to fix the electronic endoscope insertion tube, thereby greatly improving the convenience of the tool in use.

[0021] The limiting structure includes a limiting hole 12 and a limiting rail 13. The limiting hole 12 is opened through both ends of the mounting base 2. The limiting rail 13 is installed through the inside of the limiting hole 12. The bottom end of the limiting rail 13 is connected to the top end of the positioning plate 8. The cross-section of the limiting hole 12 is larger than the cross-section of the limiting rail 13. The limiting hole 12 and the limiting rail 13 form a sliding structure. In use, the mutual cooperation between the limiting hole 12 and the limiting rail 13 can limit the movement of the positioning plate 8, making the positioning plate 8 more stable when moving.

[0022] The moving mechanism includes a fixed base 16, a groove 17, a movable block 18, a moving plate 19, and a fixing assembly. The fixed base 16 is mounted on the top of the base plate 1. The groove 17 is formed inside the fixed base 16, and the movable block 18 is disposed inside the groove 17. One end of the movable block 18 is connected to one end of the mounting base 2, and the moving plate 19 is mounted on one end of the movable block 18. The fixing assembly includes a screw groove 20, a screw 21, a fixing plate 22, and a second rotating wheel 23. The screw groove 20 is formed through the interior of the moving plate 19, and the screw 21 is formed through the interior of the screw groove 20. The fixing plate 22 is rotatably mounted on one end of the screw 21. The other end of the rod 21 is equipped with a second rotating wheel 23. In use, the moving plate 19 drives the movable block 18 to move. Therefore, under the guidance of the guide rail 14 and the guide block 15, the mounting base 2 is moved. The relative position of the steel wire rope and the aluminum sleeve inside the insertion tube is adjusted to the appropriate position. Then, the second rotating wheel 23 is rotated to drive the screw 21 to move. Since the screw groove 20 and the screw 21 are threadedly connected, the screw 21 is used to drive the fixed plate 22 to move. Then, the positions of the movable block 18 and the moving plate 19 are fixed, making it more convenient and faster to move or fix the mounting base 2, thereby greatly improving the practicality of the tool in use.

[0023] The base plate 1 is equipped with a guide rail 14 inside, and a guide block 15 is provided on the outer side wall of the guide rail 14. The top end of the guide block 15 is connected to the bottom end of the mounting base 2. In use, the mutual cooperation between the guide rail 14 and the guide block 15 can guide the mounting base 2 when it moves, making the mounting base 2 more stable when it moves.

[0024] Working principle: The operator first places the electronic endoscope insertion tube inside the placement groove 7, then rotates the first rotating wheel 11 to drive the threaded rod 10 to rotate. Because of the threaded connection between the threaded hole 9 and the threaded rod 10, the threaded rod 10 moves inside the threaded hole 9. This movement, combined with the interaction between the limiting hole 12 and the limiting rail 13, allows the threaded rod 10 to drive the positioning plate 8 downwards, thereby fixing the electronic endoscope insertion tube. Then, the aluminum sleeve is fitted onto the steel wire rope of the insertion tube and placed inside the aluminum sleeve groove 3. Finally, the moving plate 19 is moved to drive the... The moving block 18 moves, thus driving the mounting base 2 to move under the guidance of the guide rail 14 and guide block 15, adjusting the relative position of the steel wire rope and aluminum sleeve inside the insertion tube, adjusting the steel wire rope to an appropriate position, and then rotating the second rotating wheel 23 to drive the screw 21 to move. Since the screw groove 20 and the screw 21 are threadedly connected, the screw 21 is used to drive the fixed plate 22 to move, thereby fixing the position of the moving block 18 and the moving plate 19. Then, the cylinder 5 is started to drive the pressure sleeve 6 to move downward, using the pressure sleeve 6 to press down on the steel wire rope and aluminum sleeve, thereby pressing the aluminum sleeve onto the steel wire rope.
