Further, referring to fig. 3, fig. 3 is a schematic structural diagram of a first shaft member in the first shaft assembly shown in fig. 2. Optionally, the first shaft member 110 includes: a first shaft 111, a first baffle 112, and a second baffle 113. The first baffle 112 includes a disc-shaped third plate surface 1121 and the second baffle 113 includes a disc-shaped fourth plate surface 1131, and axial holes (not shown) with equal diameters are provided at the centers of the third plate surface 1121 and the fourth plate surface 1131. Further, the first rotating shaft 111 includes a first shaft tube 1111 having a long shaft shape, and a disc-shaped shaft stopper 1112 provided at one end.

Alternatively, the first baffle 112 and the second baffle 113 are respectively sleeved in the first shaft tube 1111 of the first rotating shaft 111 at intervals through shaft holes on the plate surfaces thereof, and the first baffle 112 is closer to the shaft stopper 1112 than the second baffle 113. One of the first baffle 112 and the second baffle 113 is fixed relative to the first shaft tube 1111 in the circumferential direction, and the other is rotatable relative to the first shaft tube 1111 in the circumferential direction.

In an embodiment, the first side plate 220 of the first fixing plate 200 is sleeved between the third plate surface 1121 and the shaft retaining portion 1112, and the first fixing plate 200 is fixed relative to the first baffle 112. The third side plate 320 of the second fixing plate 300 is sleeved between the third plate surface 1121 and the fourth plate surface 1131, and the second fixing plate 300 is fixed relative to the second baffle 113.

It can be appreciated that, on the one hand, the first baffle 112 and the second baffle 113 are disposed at intervals, so that the first fixing plate 200 can be fixed between the shaft portion 1112 and the first baffle 112, and the second fixing plate 300 can be fixed between the first baffle 112 and the second baffle 113, and further, abrasion of the first fixing plate 200 and the second fixing plate 300 caused by direct contact and relative rotation of the first fixing plate 200 and the second fixing plate 300 can be reduced, and the first fixing plate 200 and the second fixing plate 300 can be smoother during relative rotation. On the other hand, one of the first and second shutters 112 and 113 is provided to be fixed relative to the first rotation shaft 111 in the circumferential direction, the other is rotatable relative to the first shutter 112, and the first and second fixing plates 200 and 300 are fixed relative to the second shutter 113, so that one of the first and second fixing plates 200 and 300 can be rotated relative to the other, not both can be rotated separately, and further the second rotation portion 30 connected to the first fixing plate 200 and the external product connected to the second fixing plate 300 can be rotated relative to each other.

In an embodiment, the first baffle 112 is disposed to be fixed relative to the first rotation shaft 111 in the circumferential direction, the second baffle 113 is disposed to be rotated relative to the first rotation shaft 111 in the circumferential direction, and the first fixing plate 200 is fixed relative to the first baffle 112 and the second fixing plate 300 is fixed relative to the second baffle 113. Further, the first fixing plate 200 is connected to the second rotating part 30, and the second fixing plate 300 is connected to an external product. When the external product on the second fixing plate 300 rotates, the second fixing plate 300 and the second barrier 113 fixed thereto can rotate in the circumferential direction with respect to the first rotation shaft 111. At this time, the first fixing plate 200 and the first baffle 112 and the second rotating portion 30 fixed thereto are stationary with respect to the first rotating shaft 111, and thus the external product can be rotated on the axis of the first rotating shaft 111 with respect to the second rotating portion 30.

Further, referring to fig. 4, fig. 4 is a schematic cross-sectional view of a first rotating portion of the rotating assembly shown in fig. 1. The first side plate 220 is provided with a first fixing groove 240, and the first baffle 112 is provided with a first fixing block 1122. The first fixing block 1122 is embedded in the first fixing groove 240, so that the first fixing plate 200 and the first baffle 112 are relatively fixed, and the first fixing plate 200 can drive the first baffle 112 to rotate circumferentially on the axis of the first rotating shaft 110 through the first fixing groove 240. Similarly, the third side plate 320 is provided with a second fixing groove 340 and the second baffle 113 is provided with a second fixing block 1132, and the second fixing block 1132 is embedded in the second fixing groove 340, so that the second fixing plate 300 and the second baffle 113 are relatively fixed, and the second fixing plate 300 can drive the second baffle 113 to rotate circumferentially on the axis of the first rotating shaft 110 through the second fixing groove 340.

Further, with continued reference to fig. 3, the first shaft member 110 further includes a first elastic piece 114 and a second elastic piece 115. Wherein the first spring 114 has a first arcuate top surface 1141 with a protrusion and the second spring 115 has a second arcuate top surface 1151 with a protrusion. The arcuate top surfaces of the first spring plate 114 and the second spring plate 115 are in contact, and by applying opposite pressure to the first spring plate 114 and the second spring plate 115, the first spring plate 114 and the second spring plate 115 are kept in contact, so that the relative rotation of the first fixing plate 200 and the second fixing plate 300 can be damped. The contact pressure between the two is adjusted by adjusting the distance between the two, so that adjustable damping is realized.

Optionally, the first curved top surface 1141 of the first elastic piece 114 has a first curved bottom surface 1142 that is relatively concave and the second curved top surface 1151 of the second elastic piece 115 has a second curved bottom surface 1152 that is relatively concave, and the outer edges of the two curved bottom surfaces are circular in shape and concave inward from the outer edges of the curved bottom surfaces. Further, shaft holes (not labeled in the figure) corresponding to the first shaft tube 1111 of the first rotating shaft 111 are disposed at the centers of the arc top surfaces and the arc bottom surfaces of the first elastic sheet 114 and the second elastic sheet 115, and the first elastic sheet 114 and the second elastic sheet 115 are respectively sleeved in the first rotating shaft 111 through the shaft holes. The first arc top surface 1141 contacts with the second arc top surface 1151, and the first arc bottom surface 1142 is fixed on a side of the fourth plate surface 1131 of the second baffle 113 away from the third side plate 320, so that when the second fixing plate 300 rotates relative to the first rotating shaft 111, the second fixing plate 300 drives the second baffle 113 to rotate, and the second baffle 113 can drive the first elastic sheet 114 to rotate.

Further, the first elastic piece 114 and the second elastic piece 115 are configured to relatively move on the first shaft tube 1111 of the first rotating shaft 111, so that when opposite pressure is applied to the first elastic piece 114 and the second elastic piece 115, the distance between the first arc bottom surface 1142 and the second arc bottom surface 1152 can be adjusted, and further, when the second fixing plate 300 drives the first elastic piece 114 to rotate, the first elastic piece 114 is damped due to the opposite pressure, so that the first fixing plate 200 and the second fixing plate 300 can be damped in an adjustable manner when relatively rotating.

In some embodiments, the closer the first arcuate bottom surface 1142 and the second arcuate bottom surface 1152 are, the greater the pressure exerted by the first spring plate 114 and the second spring plate 115 toward each other, and thus the greater the damping experienced by the first fixing plate 200 and the second fixing plate 300 when relatively rotated. Or the farther the first arc bottom surface 1142 and the second arc bottom surface 1152 are, the smaller the pressure applied to the first elastic sheet 114 and the second elastic sheet 115 is, and thus the smaller the damping applied to the first fixing plate 200 and the second fixing plate 300 when they relatively rotate.

Further, with continued reference to fig. 3, the first shaft member 110 may also include a spacer 116 and a securing member 117. The spacer 116 is disc-shaped, the diameter of the spacer is consistent with the circular outer edge of the second arc bottom surface 1152 of the second elastic sheet 115, and a shaft hole (not labeled in the figure) corresponding to the first rotating shaft 111 is arranged at the center of the spacer 116, and the spacer 116 is sleeved in the first rotating shaft 111 through the shaft hole. The fixing member 117 is a nut, the first rotation shaft 111 is provided with a screw thread (not shown) at the other end away from the shaft stopper 1112, the fixing member 117 is screwed into the first rotation shaft 111 by the screw thread, and the depth of screwing the fixing member 117 into the first rotation shaft 111 is adjustable by the number of screwing threads.

The gasket 116 is sleeved in the first shaft tube 1111 of the first rotating shaft 111, and the gasket 116 and the second arc bottom surface 1152 of the second elastic sheet 115 are relatively fixed, when the first elastic sheet 114 rotates relative to the first rotating shaft 111, the second elastic sheet 115 rotates relative to the first rotating shaft 111 due to damping, so that the gasket 116 can be driven to rotate synchronously. The fixing piece 117 is screwed into the first rotating shaft 111 through threads and is contacted with one side, far away from the second elastic piece 115, of the gasket 116, and therefore the fixing piece 117 can apply pressure to the gasket 116 in the axial direction of the first rotating shaft 111 by adjusting the depth of screwing into the first rotating shaft 111, and the distance between the first elastic piece 114 and the second elastic piece 115 can be adjusted through the gasket 116.

In some embodiments, the greater the depth of the fastener 117 screwed into the first shaft tube 1111, the greater the pressure applied to the spacer 116 by the fastener 117, and thus the closer the first and second spring plates 114 and 115 are, and thus the greater the damping experienced by the first and second fixing plates 200 and 300 when they are relatively rotated. The shallower the fixing member 117 is screwed into the first shaft tube 1111, the smaller the pressure applied to the spacer 116 by the fixing member 117, and thus the farther the first and second elastic pieces 114 and 115 are spaced apart, and thus the less the damping is applied when the first and second fixing plates 200 and 300 are relatively rotated.

In another embodiment, referring to fig. 5, fig. 5 is a schematic structural diagram of another embodiment of the first rotating portion of the rotating assembly shown in fig. 1. The first rotating part 20 includes a third rotating shaft member 400, a third fixing plate 500, and a fourth fixing plate 600. Specifically, the third shaft member 400 is identical to the first shaft member 110 or the second shaft member 120. The third fixing plate 500 includes a rectangular fifth plate surface 510 and a disc-shaped fifth side plate 520, and the fourth fixing plate 600 includes a rectangular sixth plate surface 610 and a disc-shaped sixth side plate 620.

Further, shaft holes corresponding to the third shaft member 400 are provided at the centers of the fifth side plate 520 and the sixth side plate 620. Further, the third shaft member 400 is connected to the fifth side plate 520 and the sixth side plate 620 through shaft holes, respectively, so that the third fixing plate 500 and the fourth fixing plate 600 can relatively rotate through the third shaft member 400, and the third shaft member 400 can provide adjustable rotation damping for the third fixing plate 500 and the fourth fixing plate 600 when the third fixing plate 500 rotates with respect to the fourth fixing plate 600.

It can be understood that the first shaft member 110 or the second shaft member 120 and the third shaft member 400 have the same purpose and function, and are connected to the side plates of the two fixing plates, so that the two fixing plates can rotate relatively and generate adjustable damping through the shaft members. Alternatively, the positions of the fifth side plate 520 of the third fixing plate 500 and the sixth side plate 620 of the fourth fixing plate 600 may be located at any positions of the third fixing plate 500 and the fourth fixing plate 600 without affecting the connection relationship between the third rotation shaft member 400 and the third fixing plate 500 and the fourth fixing plate 600. For example, the fifth side plate 520 of the third fixing plate 500 is located at the middle of the fifth plate surface 510 and the sixth side plate 620 of the fourth fixing plate 600 is located at the middle of the sixth plate surface 610.

In one embodiment, the first rotating part 20 includes a first shaft assembly 100, a first fixing plate 200, and a second fixing plate 300. The first fixing plate 200 is connected to the second rotating part 30, and the second fixing plate 300 is connected to an external product. When the external product rotates, the external product drives the second fixing plate 300 to rotate, and then the second fixing plate 300 can rotate relative to the first fixing plate 200 through the first rotating shaft assembly 100, and then the rotating assembly 10 can circumferentially rotate on the rotating axis of the first rotating shaft assembly 100. And the distance between the first elastic sheet 114 and the second elastic sheet 115 in the first rotating shaft assembly 100 can be adjusted, so that the rotation damping of the second fixing plate 300 relative to the first fixing plate 200 can be adjusted, and the rotation assembly 10 has adjustable damping during rotation.

Referring to fig. 6, fig. 6 is an overall schematic diagram of a second rotating portion of the rotating assembly shown in fig. 1. Specifically, the second rotating part 30 may include a second rotating shaft assembly 700. The second rotating shaft assembly 700 is connected to the first fixing plate 200 or the second fixing plate 300, and the rotation axis of the second rotating shaft assembly 700 is perpendicular to the rotation axis of the first rotating shaft assembly 100, so that the first rotating portion 20 can rotate circumferentially on two perpendicular rotation axes through the second rotating shaft assembly 700 and the second rotating portion 30 respectively.

When the first rotating part 20 rotates, the first rotating part 20 is rotatable with respect to the lower cover 710 by the first fixing plate 200 being coupled to the upper cover 720.

Further, referring to fig. 7, fig. 7 is a schematic diagram of an upper cover structure of the second shaft assembly shown in fig. 6. The upper cover 720 has a fan-shaped structure, and the second shaft tube 731 of the second shaft 730 is fixed at a corner of the upper cover 720. Further, referring to fig. 8, fig. 8 is a schematic view of a lower cover of the second rotating shaft assembly shown in fig. 6.

The upper cover 720 is connected to the lower cover 710 through the second shaft 731 penetrating through the bearing 732, and the upper cover 720 can rotate circumferentially on the rotation axis of the second shaft 730 relative to the lower cover 710 through the second shaft 730.

Optionally, with continued reference to fig. 8, the second spindle assembly 700 may further include a tension spring assembly 740 and a torsion spring 750. The tension spring assembly 740 includes a tension spring 741, one end of which is connected to the upper cover 720, and the other end of the tension spring 741 is connected to the lower cover 710, so that the tension spring 741 can provide a pushing force for the rotation of the upper cover 720 when the upper cover 720 rotates relative to the lower cover 710. One end of the torsion spring 750 is connected to the upper cover 720, and the other end of the torsion spring 750 is connected to the lower cover 710, so that the torsion spring 750 can provide pushing force or pulling force for the rotation of the upper cover 720 when the upper cover 720 rotates relative to the lower cover 710. The torsion spring 750 and the tension spring 740 can obtain simulation data through simulation according to the weight of the external product connected to the first rotating part 20, the upper cover 720 and the first rotating part 20, and further adjust the force ratio parameters of the torsion spring and the spring through the simulation data.

Specifically, the tension spring assembly 740 further includes a tension spring retainer 742 and an adjustment screw 743. Wherein the tension spring fixing member 742 is disposed at one end of the arc portion of the lower cover 710. Specifically, one end of the tension spring fixing member 742 may be provided with a hook ring (not shown), and the other end may be provided with a screw hole (not shown). Further, one end of the arc portion of the lower cover 710 is provided with a screw hole corresponding to the tension spring fixing member 742, and the tension spring fixing member 742 is fixed to the lower cover 710 by sequentially screwing the adjusting screw 743 into the screw holes of the lower cover 710 and the tension spring fixing member 742. Further, the hook ring of the tension spring fixing member 742 is connected to a draw hook (not shown) at one end of the tension spring 741, and the tension spring 741 is connected to the lower cover 710.

In one embodiment, the adjustment screw 743 is sequentially screwed into the gap between the screw hole of the lower cover 710 and the screw hole of the tension spring fixing member 742. Further, the tightness degree of the tension spring 741 when being connected to the upper and lower covers 720 and 710 can be adjusted by adjusting the gap between the screw hole of the lower cover 710 and the screw hole of the tension spring fixing member 742. Wherein, the larger the gap between the screw hole of the lower cover 710 and the screw hole of the tension spring fixing member 742, the more loose the tension spring 741 is when connected to the upper cover 720 and the lower cover 710. The smaller the gap between the screw hole of the lower cover 710 and the screw hole of the tension spring holder 742, the tighter the tension spring 741 is when connected to the upper cover 720 and the lower cover 710.

Further, with continued reference to fig. 7, the tension spring assembly 740 further includes a tension spring hanger 744 having one end connected to the arcuate corner of the upper cover 720. The extension spring hook 744 is an arc-shaped hook, the extension spring hook 744 can rotate relative to the upper cover 720, and the extension spring hook 744 can be attached to an arc-shaped corner of the upper cover 720 in the rotation process. When the tension spring hook 744 is completely engaged with the arc corner of the upper cover 720, the upper cover 720 is not rotated any more. Further, the other end of the tension spring hook 744 is connected with the tension spring 741 relative to a draw hook (not shown) at the other end connected with the tension spring fixing member 742, so that when the upper cover 720 rotates relative to the lower cover 710, the upper cover 720 can apply tension to the tension spring 741 through the tension spring hook 744, and the tension spring hook 744 simultaneously rotates relative to the upper cover 720, so that the same direction of the end of the tension spring hook 744, which is always connected with the tension spring 741, is achieved, the tension spring hook 744 applies tension to the tension spring 741 in a fixed direction, and the tension spring 741 can apply tension to the tension spring hook 744 in a fixed opposite direction.

In one embodiment, tension spring 741 has one end connected to tension spring retainer 742 and the other end connected to tension spring hook 744. At this time, the tension spring 741 is in a stretched state, when the upper cover 720 rotates, the tension spring hook 744 rotates along with the upper cover 720, and the direction of one end of the tension spring hook 744 connected with the tension spring 741 is unchanged, the stretched length of the tension spring 741 extends or shortens along with the rotation of the tension spring hook 744, and then the tension spring 741 increases or decreases the tension force in a fixed opposite direction to the tension spring hook 744.

Further, one end of the torsion spring 750 is connected to the other end of the arc portion of the lower cover 710 with respect to the tension spring fixing 742 by a screw. Further, the other end of the torsion spring 750 is connected to one end of the arc portion of the upper cover 720 by a screw. When the upper cover 720 rotates relative to the lower cover 710, the torsion springs 750 also rotate, and the angles of the two ends of the torsion springs 750 relative to the corners of the torsion springs 750 become larger or smaller along with the rotation of the upper cover 720, so that the torsion springs 750 can provide tensile forces or pushing forces of different directions and sizes of the upper cover 720.

Further, referring to fig. 9, fig. 9 is a schematic top view of the second rotating portion shown in fig. 8 when the upper cover is located at the first position with respect to the lower cover. When the upper cover 720 is at the first position relative to the lower cover 710, the tension spring 741 is in a stretched state, and the tension spring 741 applies a tension to the upper cover 720 through the tension spring hook 744. The angle between the two ends of the torsion spring 750 and the corners of the torsion spring 750 is larger than the static angle, and the torsion spring 750 is in an expanded state at this time, so that the torsion spring 750 also applies a pulling force to the upper cover 720. At this time, the tension spring 741 provides a tension greater than the tension provided by the torsion spring 750, and both the tension forces urge the upper cover 720 to rotate toward the second position.

Further, referring to fig. 10, fig. 10 is a schematic top view of the second rotating portion shown in fig. 8 when the upper cover is located at the second position with respect to the lower cover. When the upper cover 720 is at the second position relative to the lower cover 710, the tension spring 741 is also in a stretched state, but the stretched length is smaller than that when the upper cover 720 is at the first position relative to the lower cover 710, and further the tension spring 741 gives a tension to the upper cover 720 through the tension spring hook 744, and the tension is smaller than that when the upper cover 720 is at the first position relative to the lower cover 710, the tension spring hook 744 gives the upper cover 720. At this time, the angles of the two ends of the torsion spring 750 with respect to the corners of the torsion spring 750 are also larger than the static angles, the torsion spring 750 is in an expanded state, and the torsion spring 750 also applies a pulling force to the upper cover 720. At this time, the tension provided by the tension spring 741 is smaller than the tension provided by the torsion spring 750, and the tension of the tension spring 741 causes the upper cover 720 to rotate toward the second position, and the tension of the torsion spring 750 causes the upper cover 720 to rotate toward the first position.

In one embodiment, the arc of rotation of the upper cover 720 from the first position to the second position relative to the lower cover 710 is provided at a 90 angle. When the upper cover 720 is rotated from the first position to the second position relative to the lower cover 710, the tension spring 741 is always in a stretched state, and the stretched length thereof is continuously reduced, so that the tension spring 741 always applies a pulling force to the upper cover 720 for rotating to the second position, and the pulling force is continuously reduced. When the upper cover 720 rotates from the first position to the second position relative to the lower cover 710, the torsion spring 750 sequentially changes from the expanded state to the original state, the compressed state, and the original state to the expanded state, and further, in the process that the upper cover 720 rotates from the first position to the second position relative to the lower cover 710, the torsion spring 750 sequentially gives a pulling force to the upper cover 720 rotating toward the second position, and then the pulling force decreases to a pulling force not giving to the upper cover 720, and then to a pushing force giving to the upper cover 720 rotating toward the second position, and then the pushing force increases and then decreases until no pushing force is given to the upper cover 720, and then to a pulling force giving to the upper cover 720 rotating toward the first position, and then the pulling force increases until the upper cover 720 is in the second position.

In another embodiment, the arc of rotation of the upper cover 720 from the second position to the first position relative to the lower cover 710 is 90 °. When the upper cover 720 is rotated from the second position to the first position relative to the lower cover 710, the tension spring 741 is always in a stretched state, and the stretched length thereof is continuously increased, so that the tension spring 741 always applies a pulling force to the upper cover 720 for rotating to the second position, and the pulling force is continuously increased. When the upper cover 720 rotates from the second position to the first position relative to the lower cover 710, the torsion spring 750 sequentially changes from the expanded state to the original state, the compressed state, and the original state to the expanded state, and then, during the rotation of the upper cover 720 relative to the lower cover 710 from the second position to the first position, the torsion spring 750 sequentially applies a pulling force to the upper cover 720 which rotates to the first position, and then, the pulling force decreases to a pulling force which does not apply to the upper cover 720, and then, applies a pushing force to the upper cover 720 which rotates to the first position, and then, the pushing force increases and decreases until no pushing force is applied to the upper cover 720, and then, the pulling force increases until the upper cover 720 is in the first position.

Further, in one embodiment, when the arc planes of the upper cover 720 and the lower cover 710 are in a horizontal state with respect to the space, the factors of gravity and friction are not considered. When the upper cover 720 is in the second position with respect to the lower cover 710, the upper cover 720 is required to be manually rotated from the second position to the first position due to the common force of the tension spring 741 and the torsion spring 750. When the upper cover 720 is at the first position relative to the lower cover 710, the upper cover 720 is automatically rotated from the first position to the second position due to the tension spring 741, the torsion spring 750 and the inertia force, so that the second rotating portion 30 is semi-automatically rotated.

Further, in another embodiment, when the planes of the upper cover 720 and the lower cover 710 are in a vertical state with respect to the space and the second position of the upper cover 720 is higher than the first position, it is considered that the weight of the external product is mounted on the first rotating part 20 and the weight of the upper cover 720 and the first rotating part 20 themselves are greater than the force provided by the tension spring 741 and the torsion spring 750 together. When the upper cover 720 is in the first position with respect to the lower cover 710, the upper cover 720 needs to be manually rotated from the first position to the second position due to the combined force of the tension spring 741 and the torsion spring 750 and the weight taken into consideration. When the upper cover 720 is at the second position relative to the lower cover 710, the upper cover 720 can automatically rotate from the second position to the first position due to the acting force of the tension spring 741 and the torsion spring 750 and the gravity considered, so that the semi-automatic rotation of the second rotating portion 30 can be realized.

Optionally, with continued reference to fig. 8, the second shaft assembly 700 may include an arcuate slide 760. Wherein, the arc-shaped sliding bar 760 is disposed at a side of the lower cover 710 facing the upper cover 720, and the arc-shaped sliding bar 760 is matched with an arc-shaped edge of the upper cover 720 for guiding the rotation of the upper cover 720.

Alternatively, with continued reference to fig. 7 and 8, the second spindle assembly 700 may include a first magnetic attraction member 770 and a second magnetic attraction member 780. The first magnetic attraction member 770 may be disposed at any position of the arc-shaped edge portion of the upper cover 720, and the second magnetic attraction member 780 may be disposed at any position of the arc-shaped edge portion of the lower cover 710 or any position of the upper cover 720 where the rotation assembly 10 can magnetically attract the first magnetic attraction member 770 and the attraction force can be fixed.

In one embodiment, the first magnetic attraction member is disposed at an end of the arcuate edge portion of the upper cover 720, and the second magnetic attraction member 780 is disposed directly below the position of the first magnetic attraction member 770 when the upper cover 720 is in the second position. Further, when the upper cover 720 rotates relative to the lower cover 710, the first magnetic attraction member 770 magnetically attracts the second magnetic attraction member 780, so that the upper cover 720 and the lower cover 710 can be relatively fixed.

Optionally, the second shaft assembly 700 further includes a gear assembly 790, the gear assembly 790 being disposed between the upper and lower covers 720 and 710 and configured to provide damping of relative rotation of the upper and lower covers 720 and 710. In one embodiment, referring to fig. 8, the gear assembly 790 includes a first gear 791 disposed on the lower cover 710, wherein the first gear 791 is a damping gear. With continued reference to fig. 7, the gear assembly 790 further includes a second gear 792 disposed on the upper cover. Further, the first gear 791 and the second gear 792 are engaged, and when the upper cover 720 is rotated with respect to the lower cover 710, the first gear 791 follows the rotation of the upper cover 720 and generates damping, so that the upper cover 720 can smoothly rotate with respect to the lower cover 710.

Optionally, in an embodiment, a lubricant is added to the meshing position of the first gear 791 and the second gear 792 and/or a noise damping foam is added to the connection of the second shaft 731 and the bearing 732 to enable rotation with less noise when the upper cover 720 rotates relative to the lower cover 710. The noise-reducing foam is added at the connection between the first baffle 112 and the second fixed plate 300 and/or at the connection between the first elastic sheet 114 and the second elastic sheet 115, so as to realize that the first fixed plate 200 can rotate with less noise when rotating relative to the second fixed plate 300.

In one embodiment, the rotating assembly 10 includes a first rotating portion 20 and a second rotating portion 30. Wherein, first rotation portion 20 and second rotation portion 30 pass through the screw connection, and the external product passes through the fastener and is connected with first rotation portion 20. When the first rotating portion 20 rotates, the first rotating portion 20 drives the external product to rotate, and the external product can further rotate circumferentially on a rotation axis of the rotating assembly 10 through the first rotating portion 20. And the damping of the first rotating part 20 when rotating can be adjusted to enable the external product to have adjustable damping when rotating. When the second rotating portion 30 rotates, the second rotating portion 30 drives the external product to rotate through the first rotating portion 20, and the external product can further rotate circumferentially on the other rotation axis of the rotating assembly 10 through the second rotating portion 30. And due to the arrangement of the second rotating part 30, when the second rotating part 30 rotates from the first position to the second position or from the second position to the first position, the second rotating part 30 can drive the external product to rotate semi-automatically.
