[0023] Reference Figure 1-Figure 4A gearbox gear mounting structure includes a fixed plate 1, an inner circumferential wall surface of the fixed plate 1 is movably sleeved with a toothed plate 2, and also includes a replacement component, which is arranged on one side of the fixed plate 1 and is used to replace the toothed plate 2. The replacement component includes: two first fixing holes 3, both of which are arranged on one side of the fixed plate 1, two connecting holes 4 are arranged on the outer circumferential wall surface of the fixed plate 1, and the connecting holes 4 are connected to the first fixing holes 3. The inner circumferential wall surface of the toothed plate 2 is provided with two limiting grooves 6, and the inner circumferential wall surface of the connecting hole 4 is movably sleeved with a limiting plate 7, and the limiting plate 7 and the limiting groove 6 are movably sleeved. The first fixing hole 3 is movably connected with the limiting plate 7. A second fixing hole 9 is provided on one side of the limiting plate 7. A connecting column 8 is movably connected to the inner wall of the second fixing hole 9. A rotating plate 10 is fixedly installed on both ends of the connecting column 8. A hexagonal groove 11 is provided on one side of the rotating plate 10. Two fixing grooves 12 are provided on one side of the inner part of the first fixing hole 3. A limiting tube 13 is movably connected to the inner wall of the fixing groove 12. The limiting tube 13 is fixedly installed with the limiting plate 7. A spring 14 is movably connected to the inner wall of the limiting tube 13. The spring 14 is movably connected to the fixing groove 12.

[0024] In this embodiment, the inner wall surface of the toothed disc 2 is provided with two positioning grooves 15, the outer wall surface of the fixed disc 1 is fixedly provided with two positioning plates 16, the positioning plates 16 are movably sleeved with the positioning grooves 15, a plurality of fixing plates 17 are fixedly provided on both sides of the fixed disc 1, and a limiting ring 18 is fixedly provided on both sides of the fixed disc 1, lubricating oil is applied between the second fixing hole 9 and the connecting column 8, and a third fixing hole 5 is provided on one side of the rotating plate 10.

[0025] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: through the setting of the fixed disk 1, when the user needs to replace the toothed disk 2, at this time, through the set hexagonal slot 11, the user inserts the hexagonal wrench into the inside of the hexagonal slot 11 and twists to drive the rotating plate 10 to rotate. Since the rotating plate 10 is similar to an ellipse and the bottom protrudes, the rotating plate 10 contacts the inner side of the first fixing hole 3 to lift the connecting column 8. At the same time, the connecting column 8 moves and drives the limiting plate 7 to enter the interior of the connecting hole 4 until the third fixing hole 19 contacts and fits with the inner side of the connecting hole 4, so that the rotating plate 10 cannot rotate by itself, and then the limiting plate 7 remains in the interior of the connecting hole 4, thereby moving the toothed disk 2 so that it is no longer connected with the fixed disk 1, and the toothed disk 2 is removed, and then The new toothed disc 2 is picked up, the positioning plate 16 and the fixed disc 1 are positioned through the provided fixing groove 15, and the toothed disc 2 is sleeved on the outside of the fixed disc 1, so that the rotating plate 10 is rotated and reset under the push of the spring 14, and the limit plate 7 moves into the inside of the limit groove 6 to engage and limit the toothed disc 2, thereby completing the installation of the new toothed disc 2. During use, due to the push of the spring 14 and the centrifugal force of rotation, the limit plate 7 will not slide out of the inside of the limit groove 6, and there will be no situation where the toothed disc 2 slips off the outside of the fixed disc 1 due to fixation failure, thereby comprehensively achieving the effect of replacing the toothed disc 2, so that the toothed disc 2 will not lose its fixation after being installed, and the fixed disc 1 and the toothed disc 2 are prevented from being separated. At the same time, the replacement of the toothed disc 2 is more convenient, and only the rotating plate 10 needs to be rotated, which is more practical.
