At the same time, when the clutch mechanism is installed on the equatorial mount, the traditional equipment does not have a buffer mechanism, so when the clutch mechanism is installed, the equatorial mount vibrates, affecting the operation of the equatorial mount.

[0032] A clutch device 6, the outer wall of the clutch device 6 is rotatably connected to the inner wall of the middle portion of the frame 1;

[0033] The clutch device 6 includes a sliding plate 61, the inner wall of the sliding plate 61 is fixedly connected to a magnetic ring 62, a rotating disk 64 is arranged at the bottom of the sliding plate 61, the inner wall of the rotating disk 64 is rotatably connected to a rotating shaft 68, an adjusting plate 65 is arranged inside the rotating disk 64, an adjusting column 66 is rotatably connected to the inner wall of the rotating disk 64, a toothed disk 67 is fixedly connected to the bottom of the adjusting column 66, an adjusting sleeve 69 is slidably connected to the outer wall of the adjusting column 66 through a sliding groove 610, and a permanent magnet 63 is fixedly connected to the outer wall of the adjusting sleeve 69 through a fixed sleeve, and the adjusting sleeve 65 is arranged inside the rotating disk 64. 9 slides up and down, causing the adjustment column 66 to rotate, thereby driving the toothed disc 67 to rotate, and then adjusting the angle of the adjustment plate 65 on the turntable 64. The top of the turntable 64 is fixedly connected to the bottom of the buffer mechanism 5 through the connecting block 611, the outer wall of the buffer mechanism 5 is slidably connected to the outer wall of the fixed block 2, the bottom of the fixed block 2 is fixedly connected to the top of the frame 1, the outer wall of the magnetic ring 62 is slidably connected to the inner wall of the frame 1, the inner wall of the frame 1 is slidably connected to the inner wall of the sliding plate 61, and the outer wall of the turntable 64 is rotatably connected to the inner wall of the frame 1.

[0034] The inner wall of the adjusting plate 65 is fixedly connected to the outer wall of the rotating shaft 68. When the angle of the adjusting plate 65 fits the turntable 64, the liquid cannot hit the adjusting plate 65, so the turntable 64 stops rotating. When the angle of the adjusting plate 65 is perpendicular to the turntable 64, the liquid can hit the adjusting plate 65 to the greatest extent, so that the rotation speed of the turntable 64 is the fastest. The outer wall of the rotating shaft 68 is meshed with the outer wall of the gear plate 67, and the outer wall of the adjusting sleeve 69 is slidably connected to the inner wall of the connecting block 611. The buffer mechanism 5 includes a rotating shaft 51, and the outer wall of the rotating shaft 51 is rotatably connected to a sliding ring 52.

The top of the fixed block 2 is fixedly connected to the limiting block 53, and the outer wall of the limiting block 53 contacts the outer wall of the sliding ring 52, and the outer wall of the sliding ring 52 is slidably connected to the outer wall of the fixed block 2.

[0036] Working principle:

[0037] When in use, the clutch mechanism is first installed on the equatorial mount, and the clutch mechanism is docked with the equatorial mount through the buffer mechanism 5 on the frame 1, so that the clutch mechanism is installed on the equatorial mount. When docking the equatorial mount, the buffer mechanism 5 is used to buffer the impact force of the clutch mechanism directly hitting the equatorial mount, thereby reducing the impact force on the equatorial mount, and further reducing the impact on the equatorial mount. Liquid is filled in the cavity between the clutch mechanism and the stepper motor 3, and the output end of the stepper motor 3 is fixed with a fan blade 4, so the fan blade 4 is driven by the stepper motor 3 to rotate, and the fan blade 4 drives the liquid in the cavity to rotate. The liquid in the cavity rotates under the rotation of the fan blade 4. After the clutch mechanism is installed on the equatorial mount, the sliding plate 61 on the sliding clutch device 6 is adjusted to adjust the adjustment plate 65 in the cavity. After the angle of the adjustment plate 65 is changed, the rotating liquid hits the adjustment plate 65, so that the clutch device 6 can rotate, thereby driving the buffer mechanism 5 to rotate synchronously, and further driving the equatorial mount connected to the buffer mechanism 5 to move.

[0038] When the clutch device 6 is installed on the equatorial mount, the rotating shaft 51 in the buffer mechanism 5 first contacts the equatorial mount, and as the rotating shaft 51 continues to move toward the equatorial mount, the rotating shaft 51 slides into the connecting sleeve 56, but the sliding ring 52 is connected to the frame 1 through the top spring 54 and the resistance rod 55, and the sliding ring 52 is rotatably connected to the rotating shaft 51. Therefore, driven by the rotating shaft 51, the sliding ring 52 synchronously compresses the top spring 54, and the resistance of the resistance rod 55 gives the sliding ring 52 a supporting force. Therefore, under the action of the top spring 54 and the resistance rod 55, the sliding ring 52 slowly slides along the outer wall of the fixed block 2 toward the frame 1. Therefore, under the contraction of the rotating shaft 51, the impact force on the equatorial mount is reduced.

[0039] When disassembling the clutch mechanism and the equatorial mount, it is only necessary to remove the rotating shaft 51 from the equatorial mount. When the pressure of the equatorial mount is removed, the compressed top spring 54 of the rotating shaft 51 can be reset, thereby driving the sliding ring 52 and the resistance rod 55 to reset synchronously. However, a limit block 53 is fixed on the fixed block 2, and under the restriction of the limit block 53, the sliding position of the sliding plate 61 can be limited.

[0040] After the clutch mechanism is installed, the sliding plate 61 on the sliding frame 1 drives the magnetic ring 62 to slide up and down in the frame 1 through the sliding plate 61. Because the magnetic ring 62 and the permanent magnet 63 on the adjusting sleeve 69 are attracted to each other, when the magnetic ring 62 slides up and down, the permanent magnet 63 is synchronously driven to slide up and down, and then the adjusting sleeve 69 is driven to slide up and down. Because the adjusting sleeve 69 slides on the adjusting column 66, the adjusting column 66 is provided with a slide groove 610, and the adjusting sleeve 69 is fixed with a slide ball, and the slide ball is in the slide groove 610. Slide, and then when the adjusting sleeve 69 slides on the adjusting column 66, because the adjusting sleeve 69 cannot rotate, but the adjusting column 66 can rotate, the sliding ball slides along the sliding groove 610, forcing the adjusting column 66 to rotate, thereby driving the toothed disc 67 at the bottom of the adjusting column 66 to rotate, and when the toothed disc 67 rotates, the rotating shaft 68 meshing with the toothed disc 67 is synchronously driven to rotate, and the adjusting plate 65 is fixed to the rotating shaft 68, and then when the rotating shaft 68 rotates, the adjusting plate 65 is synchronously driven to rotate, thereby changing the angle of the adjusting plate 65.

[0041] The rotating liquid in the cavity hits the adjustment plate 65, so that the adjustment plate 65 drives the turntable 64 to rotate, and the turntable 64 drives the connecting block 611 to rotate. Because the adjustment sleeve 69 slides in the connecting block 611, the adjustment sleeve 69 and the connecting block 611 rotate synchronously, but the height position of the adjustment sleeve 69 can be changed synchronously with the up and down position of the permanent magnet 63. The connecting block 611 transmits the rotating force of the turntable 64 to the rotating shaft 51 through the connecting sleeve 56, thereby driving the rotating shaft 51 to rotate. When the rotating shaft 51 rotates, the sliding plate 61 is slid again to adjust the angle of the adjustment plate 65, thereby changing the rotation speed of the rotating shaft 51.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
