The staff drives the rotating block 34 and the screw rod 32 to rotate so that the damping plate 33 no longer abuts against the mounting seat 1, and the limitation on the position of the guide plate 31 is released. The staff releases the fixed plate 39, and the second tension spring 40 drives the fixed plate 39 and the prism 36 to move in the opposite direction so that the block 37 is inserted into the slot 38, limiting the position of the rotating block 34 and the guide plate 31 at this time to prevent the end of the guide plate 31 from sliding out of the guide groove 30.

[0024] A method for using a gear transmission with stable transmission in this embodiment, using the above-mentioned gear transmission with stable transmission, includes the following steps: Step 1: The mounting base 1 is fixedly mounted at a preset position, and the gearbox body 2 and the output shaft 4 are driven to rotate relative to the mounting base 1 and the drive shaft 3 by rotating the adjustment structure, so that the output shaft 4 is at a preset position; Step 2: Drive the corresponding rotating seat 5 to slide relative to the output shaft 4 through the translation mechanism, and synchronously connect the rotating seat 5 and the corresponding first speed change gear 7 together through the synchronous rotation component; Step 3: When the external driving device drives the driving shaft 3 to rotate, the driving shaft 3 drives several second speed gears 8 to rotate synchronously, and the second speed gears 8 drive the corresponding first speed gears 7 to rotate. A first speed gear 7 synchronously connected to the rotating seat 5 drives the output shaft 4 to rotate through a sliding member, and the output shaft 4 can drive the external components to rotate.

[0025] Working principle: During operation, the staff will fix the mounting seat 1 in a preset position, and drive the gearbox body 2 and the output shaft 4 to rotate relative to the mounting seat 1 and the driving shaft 3 by rotating the adjustment structure, so that the output shaft 4 is in the preset position, and the corresponding rotating seat 5 is driven to slide relative to the output shaft 4 by the translation mechanism, and the rotating seat 5 and the corresponding first speed gear 7 are synchronously connected together through the synchronous rotation component. When the external driving device drives the driving shaft 3 to rotate, the driving shaft 3 drives several second speed gears 8 to rotate synchronously, and the second speed gear 8 drives the corresponding first speed gear 7 to rotate. A first speed gear 7 synchronously connected to the rotating seat 5 drives the output shaft 4 to rotate through a sliding member, and the output shaft 4 can drive the external components to rotate. The position of the output shaft 4 can be adjusted according to actual needs, and the corresponding first speed gear 7 and the rotating seat 5 can be stably and synchronously connected according to the needs of the speed gear, so as to realize transmission of different speeds and improve the stability and service life of the transmission. When the translation mechanism drives the rotating seat 5 to move horizontally, the rotating seat 5 drives the synchronous block 47 to slide in the synchronous groove 46, and the rotating seat 5 drives the first positioning column 12 and the second positioning column 13 to move toward the corresponding synchronous disk 9. Since the first positioning groove 10 and the second positioning groove 11 are staggered, it is ensured that the end of the first positioning column 12 can be inserted into the first positioning groove 10 or the end of the second positioning column 13 can be inserted into the second positioning groove 11. Since the ends of the first positioning column 12 and the second positioning column 13 away from the rotating seat 5 are both truncated cone-shaped structures, during the movement of the first positioning column 12 or the second positioning column 13, the end of the first positioning column 12 slides in contact with the inner wall of the first positioning groove 10 or the end of the second positioning column 13 slides in contact with the inner wall of the second positioning groove 11. The first positioning column 12 and the second positioning column 13 correct the position of the rotating seat 5, and finally the first positioning column 12 or the second positioning column 13 removes the circular The remaining end of the trapezoidal structure is also inserted into the corresponding first positioning groove 10 or the second positioning groove 11, ensuring that the corresponding first speed change gear 7 and the synchronous disk 9 are synchronously connected with the rotating seat 5. Since the rotating seat 5 slides relative to the output shaft 4, when the end of the first positioning column 12 is not inserted into the first positioning groove 10, the first positioning column 12 slides relative to the rotating seat 5, the compression spring 17 is in a compressed state, and the anti-slip block 14 slides relative to the anti-slip groove 16. On the contrary, when the end of the second positioning column 13 is not inserted into the second positioning groove 11, the second positioning column 13 slides relative to the rotating seat 5. The design of the anti-slip block 14 and the anti-slip groove 16 prevents the first positioning column 12 or the second positioning column 13 from being separated from the groove 15. When the corresponding rotating seat 5 is synchronously connected with one of the synchronous disks 9 and the first speed change gear 7 respectively, and the corresponding rotating seat 5 rotates, the rotating seat 5 can drive the output shaft 4 to rotate synchronously through the synchronous block 47; The staff drives the movable plate 20 and the slide plate 22 to move relative to the adjustment plate 18 through the handle 28, the first tension spring 23 is in a tensioned state, and the positioning plate 24 is disengaged from the corresponding positioning hole 25, and the limitation on the horizontal position of the adjustment plate 18, the movable ring 6 and the rotating seat 5 is released. The staff drives the movable plate 20 to move in the horizontal direction, the slide plate 22 drives the movable ring 6 and the rotating seat 5 to move in the horizontal direction through the adjustment plate 18, and the adjustment plate 18 drives the guide sleeve 27 to slide relative to the guide frame 26. The design of the guide frame 26 and the guide sleeve 27 allows the movable ring 6 and the adjustment plate 18 to move smoothly in the horizontal direction. When the movable ring 6 drives the rotating seat 5 to move to the preset position, the staff releases the handle 28, and the first tension spring 23 drives the slide plate 22 and the movable plate 20 to move, so that the positioning plate 24 is inserted into a corresponding positioning hole 25, so that the movable plate 20 can be fixed relative to the gearbox body 2. When the rotating seat 5 rotates, the rotating seat 5 rotates relative to the movable ring 6 and the adjustment plate 18. When it is necessary to drive the gearbox body 2 to rotate relative to the mounting seat 1, the staff drives the fixed plate 39 and the prism 36 to slide relative to the fixed plate 35. The second tension spring 40 is in a stretched state, and the block 37 is no longer located in the slot 38, releasing the lock on the position of the rotating block 34 and the screw rod 32. The staff drives the rotating block 34 and the screw rod 32 to rotate so that the damping plate 33 no longer abuts against the mounting seat 1, and the limitation on the position of the guide plate 31 is released. The staff releases the fixed plate 39, and the second tension spring 40 drives the fixed plate 39 and the prism 36 to move in the opposite direction so that the block 37 is inserted into the slot 38, limiting the position of the rotating block 34 and the guide plate 31 at this time to prevent the end of the guide plate 31 from sliding out of the guide groove 30. Similarly, the staff drives the other damping plates 33 no longer abut against the mounting seat 1. Then the staff can drive the gearbox body 2 to rotate relative to the mounting seat 1, and the gearbox body 2 can drive the end of the guide plate 31 to slide in the guide groove 30, changing the output shaft 4 relative to the mounting seat 1 When the position of the gearbox body 2 does not need to be adjusted, similarly, the above steps are performed in reverse order to make the damping plate 33 abut against the mounting seat 1 again, so that the gearbox body 2 is fixed relative to the mounting seat 1. When the gearbox body 2 needs to be removed, and the damping plate 33 is no longer abutted against the mounting seat 1, and the block 37 is no longer located in the slot 38, the staff drives the guide plate 31 to move so that the guide plate 31 is disengaged from the guide slot 30, and the removal of the guide plate 31 is completed, and the limitation on the position of the gearbox body 2 is released. The staff drives the gearbox body 2 to move in a direction away from the mounting seat 1, and the first speed gear 7 slides horizontally relative to the second speed gear 8, and the plug block 44 is disengaged from the slot 45, so that the removal of the gearbox body 2 is completed, which is convenient for replacing the components located on the mounting seat 1 or the gearbox body 2. When the gearbox body 2 rotates, the end of the drive shaft 3 away from the mounting seat 1 is supported by the support shaft 43 and the plug block 44, thereby increasing the stability of the drive shaft 3 during rotation.
