Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model provides Figure 1-3 The inclination adjustment mechanism of the ophthalmic surgical microscope shown in the figure comprises a reduction seat 1 and a screw. An intermediate shaft 14 is rotatably installed inside the reduction seat 1. A fixed seat 7 is installed at the end of the intermediate shaft 14. The fixed seat 7 is used to fix and connect the microscope. The reduction seat 1 is installed at the microscope use position, so that the intermediate shaft 14 drives the fixed seat 7 to rotate, and the cleaning angle of the microscope connected to the fixed seat 7 can be adjusted. The outer wall of the intermediate shaft 14 is symmetrically sleeved with a second bearing 8. The second bearing 8 can ensure the stability of the rotation of the intermediate shaft 14. The ends of the outer wall of the intermediate shaft 14 are rotatably connected with an adjustment retaining ring 10 and a locking retaining ring 15 respectively. The adjustment retaining ring 10 and the locking retaining ring 15 are connected to the reduction seat 1 through screws. A round nut 16 is threadedly sleeved on the end of the outer wall of the shaft 14, and the outer wall of the round nut 16 is rotatably sleeved on the locking retaining ring 15. Under the limitation of the round nut 16, the adjusting retaining ring 10 and the locking retaining ring 15, the stability of the rotational installation of the intermediate shaft 14 and the reduction seat 1 can be guaranteed. A first adjusting component for driving the intermediate shaft 14 to rotate is installed on one side inside the reduction seat 1. The first adjusting component can quickly drive the intermediate shaft 14 and the fixed seat 7 to rotate, thereby quickly adjusting the inclination angle of the microscope. A second adjusting component for driving the intermediate shaft 14 to rotate is installed on the other side inside the reduction seat 1. The second adjusting component can accurately adjust the angle of the intermediate shaft 14 and the fixed seat 7, thereby accurately adjusting the inclination angle of the microscope.
[0024] Further, the first adjusting component includes a connecting rod bevel gear 5 and a transmission worm 9, the connecting rod bevel gear 5 is rotatably connected to the inside of the reduction seat 1, the transmission worm 9 is installed on the outer wall of the intermediate shaft 14, the transmission worm 9 is meshed with the connecting rod bevel gear 5, and the size of the transmission worm 9 is similar to that of the connecting rod bevel gear 5, so that when the handle 2 drives the connecting rod bevel gear 5 to rotate, the transmission worm 9 can drive the intermediate shaft 14 and the fixed seat 7 to rotate at the same angular velocity, the end of the connecting rod bevel gear 5 is fixedly installed with the handle 2 by screws, one side of the inner cavity of the reduction seat 1 is fixedly installed with a connecting retaining ring 3 by screws, the outer wall of the connecting rod bevel gear 5 is symmetrically sleeved with a first bearing 4, the first bearing 4 can reduce the resistance to the rotation of the connecting rod bevel gear 5, one end of the outer wall of the connecting rod bevel gear 5 is rotatably sleeved with the connecting retaining ring 3, and the other side of the reduction seat 1 is rotatably provided with a screw retaining ring 6, the screw retaining ring 6 is threadedly connected to the end of the connecting rod bevel gear 5, under the limitation of the connecting retaining ring 3 and the screw retaining ring 6, the stability of the rotational connection between the connecting rod bevel gear 5 and the reduction seat 1 can be guaranteed.
[0025] Furthermore, the second adjustment component includes a transverse worm 13 and a transmission bevel gear 17. The transverse worm 13 is rotatably sleeved inside the reduction seat 1. The transmission bevel gear 17 is installed on the outer wall of the intermediate shaft 14. The transmission bevel gear 17 is meshed with the transverse worm 13. The size of the transverse worm 13 is much smaller than the size of the transmission bevel gear 17. Therefore, when the transverse worm 13 is driven to rotate by the knob 11, the angular velocity of the intermediate shaft 14 is much smaller than the angular velocity of the knob 11. Therefore, the microscope installed on the fixed seat 7 can be finely adjusted inclination. The outer wall of the transverse worm 13 is rotatably sleeved with a mounting plate 12. The mounting plate 12 is installed on one side of the reduction seat 1 by screws. The plate 12 can limit the transverse worm 13 to ensure the stability of the rotational connection between the transverse worm 13 and the reduction seat 1. The end of the outer wall of the transverse worm 13 is installed with a knob 11 by a screw, and the outer wall of the transverse worm 13 can slide relative to the mounting plate 12, so that pulling the knob 11 can drive the transverse worm 13 to slide and separate from the transmission bevel gear 17. Pressing the knob 11 toward the reduction seat 1 can make the transverse worm 13 slide and dock with the transmission bevel gear 17. When the transverse worm 13 slides and separates from the transmission bevel gear 17, the first adjusting component can quickly rotate the driving intermediate shaft 14 to avoid the transverse worm 13 from meshing with the transmission bevel gear 17 to prevent the intermediate shaft 14 from rotating.
