[0012] As a further description of the above technical solution:

[0013] Limiting ring 2 is fixedly connected to the upper middle part of the outer wall of the connecting rod.

[0014] As a further description of the above technical solution:

[0015] One end of the spring is attached to the outer wall of the housing.

[0016] As a further description of the above technical solution:

[0017] A circular plate is fixedly connected to the top of the top cover.

[0018] This utility model has the following beneficial effects:

[0019] 1.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model provides: an adjusting gear mounting structure, including a housing 1, with rotating shafts 8 rotatably connected to both the left and right ends of the housing 1, and a bevel gear 14 fixedly connected to the other end of the rotating shafts 8, a connecting plate 2 attached to the top of the housing 1, bolts 7 threadedly connected to the top of the connecting plate 2 near the edge, a top cover 3 fixedly connected to the middle of the top of the connecting plate 2, a hollow tube adsorption 5 provided in the middle of the inner side of the top cover 3, a bevel gear 12 adsorbed at the bottom end of the hollow tube adsorption 5, a vacuum generator 6 connected to the top of the hollow tube adsorption 5, the outer wall of the bevel gear 14 meshing with the outer side of the bevel gear 12, and a limit ring 15 fixedly connected to the upper middle part of the outer wall of the connecting rod 10;

[0029] Specifically, the external protective structure of the outer casing 1 protects the internal components from the influence of the external environment and provides basic support. The connecting plate 2 is attached to the top of the outer casing 1. In order to firmly fix the connecting plate 2 to the outer casing 1, multiple threaded holes are evenly distributed near the edge of the top of the connecting plate 2. Each threaded hole is threaded with a bolt 7. The connecting plate 2 is fixedly connected to the top cover 3. A hollow tube adsorption 5 is set in the middle of the inner side of the top cover 3. The top of the hollow tube adsorption 5 is connected to a vacuum generator 6. The vacuum generator 6 is a negative pressure device. By means of the principle, the air inside the hollow tube adsorption 5 is extracted, so that a negative pressure environment is formed inside, thereby realizing the adsorption of the bevel gear 12.

[0030] Please see the appendix Figure 3 - Appendix Figure 5A connecting rod 10 is rotatably connected to the bottom inner side of the outer casing 1. A sliding rod 16 is slidably connected to the top inner side of the outer casing 1. A blocking plate 9 is fixedly connected to one end of the sliding rod 16, and a C-shaped plate 13 is fixedly connected to the other end of the sliding rod 16. A spring 17 is provided on the outer wall of the sliding rod 16. A limit ring 11 is fixedly connected to the lower middle part of the outer wall of the connecting rod 10. One end of the spring 17 is in contact with the outer wall of the outer casing 1. A circular plate 4 is fixedly connected to the top of the top cover 3.

[0031] Specifically, the slide bar 16 can move freely upwards while being restricted by the guide groove of the track, ensuring the smoothness and accuracy of the slide bar 16's movement. The other end of the slide bar 16 is also reliably connected to the C-shaped plate 13, which, together with the spring 17, has a good elastic effect. One end of the spring 17 is in contact with the outer wall of the outer shell 1, while the other end may contact the C-shaped plate 13 and the component. The circular plate 4 has multiple functions; it can increase the structural strength of the top cover 3 and improve the load-bearing capacity of the top cover 3.

[0032] Working principle: When the adjusting gear needs to be installed, the vacuum generator 6 and the hollow tube adsorption 5 are used to vacuum adsorb the bevel gear 12, which is then engaged with the bevel gear 14 rotatably connected to the rotating shaft 8. Then, the outer shell 1 and the connecting plate 2 are connected by bolts 7, and the top cover 3 and the circular plate 4 are fixed to ensure that the hollow tube adsorption 5 is in a vertical state. Then, the slide rod 16 connected to the blocking plate 9 is used to finely adjust the C-shaped plate 13 through the spring 17, thereby ensuring that multiple C-shaped plates 13 are in the center position of the outer shell 1. This makes it easier for the operator to install the bevel gear 12 in the center position, improving the efficiency and accuracy of gear installation, and avoiding the situation where the structure is misaligned and the gear is crushed.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
