[0037] For details, please refer to Figures 1 to 4 , the embodiment of the present application provides a rotating mechanism. The rotating mechanism includes a fixed member 10, a first rotating member 20 and a second rotating member 30. The fixed member 10 is configured with a first rotating shaft 110 extending along a first direction. The first rotating member 20 is configured with a first connecting hole 210, and the first rotating shaft 110 is rotatably connected to the first connecting hole 210. The first rotating member 20 is configured with a second rotating shaft 220 extending along a second direction, and the second direction is perpendicular to the first direction. The second rotating member 30 is arranged on a side of the first rotating member 20 away from the fixed member 10, and the second rotating member 30 is configured with a second connecting hole 310, and the second connecting hole 310 is connected to the first connecting hole 210. The first rotating shaft 110 passes through the first connecting hole 210 and is disposed in the second connecting hole 310. The second rotating member 30 is also configured with a third connecting hole 320, and the second rotating shaft 220 is rotatably connected to the third connecting hole 320. Among them, the aperture of the second connecting hole 310 is larger than the diameter of the first rotating shaft 110.

[0038] In some embodiments, the first rotating member 20 is rotatably mounted on the first rotating shaft 110 of the fixed member 10, and the second rotating member 30 is rotatably mounted on the second rotating shaft 220 of the first rotating member 20, so that the first rotating member 20 and the second rotating member 30 can rotate around the first rotating shaft 110, and the second rotating member 30 can rotate around the second rotating shaft 220, so that the second rotating member 30 can be adjusted in two directions. Since the aperture of the second connecting hole 310 is larger than the diameter of the first rotating shaft 110, when the second rotating member 30 rotates around the second rotating shaft 220, the first rotating shaft 110 can rotate to a certain extent in the second connecting hole 310 to prevent the first rotating shaft 110 from interfering with the rotation of the second rotating member 30 around the second rotating shaft 220. Based on the above installation method, the first rotating member 20 and the second rotating member 30 can be both installed on the fixed member 10, so that the structure of the rotating mechanism is compact and occupies less installation space.

[0039] In some embodiments, Figure 2As shown, the first direction may be the front-to-back direction, and the second direction may be the left-to-right direction. Then the first rotating member 20 and the second rotating member 30 may realize the up-down rotation based on the first rotating shaft 110, that is, Figure 1 The second rotating member 30 can realize the rotation in the front-rear direction based on the second rotating shaft 220, that is, Figure 1 After the rotating mechanism is applied to a display, the angle adjustment of the screen in the up-down direction and the front-back direction can be realized.

[0040] It is understandable that when the angle of the second rotating member 30 in the up-down direction needs to be adjusted, the first rotating member 20 and the second rotating member 30 can be rotated around the first rotating shaft 110 at the same time, so that the two rotate synchronously in the first rotation direction, and finally the up-down angle adjustment of the second rotating member 30 is achieved. When the angle of the second rotating member 30 in the front-back direction needs to be adjusted, the second rotating member 30 can be rotated around the second rotating shaft 220, so that the second rotating member 30 rotates in the second rotation direction, and the front-back angle adjustment is achieved.

[0041] The diameter of the first connecting hole 210 on the first rotating member 20 may be the same as the diameter of the first rotating shaft 110, so that the first rotating member 20 can rotate smoothly around the first rotating shaft 110. The diameter of the third connecting hole 320 on the second rotating member 30 may be the same as the diameter of the second rotating shaft 220, so that the second rotating member 30 can rotate smoothly around the second rotating shaft 220.

[0042] The diameter of the second connection hole 310 on the second rotating member 30 is larger than the diameter of the first rotating shaft 110, and the circular shape of the second connection hole 310 is located on the axis of the first rotating shaft 110. Thus, the first rotating shaft 110 can be prevented from interfering with the rotation of the second rotating member 30 around the second rotating shaft 220. When the second rotating member 30 rotates around the second rotating shaft 220, when the first rotating shaft 110 contacts the hole wall surface of the second connection hole 310, the maximum rotation angle of the second rotation direction is limited.

[0043] In some embodiments, the first rotating shaft 110 may be integrally formed with the fixing member 10. The first rotating shaft 110 may also be welded to the fixing member 10. The first rotating shaft 110 may also be bonded to the fixing member 10.

[0044] In some embodiments, the second rotating shaft 220 may be integrally formed with the first rotating member 20. The second rotating shaft 220 may also be welded to the first rotating member 20. The second rotating shaft 220 may also be bonded to the first rotating member 20.

[0045] There is no direct connection between the diameter of the first rotating shaft 110 and the diameter of the second rotating shaft 220 , and the diameter and length of the first rotating shaft 110 and the diameter and length of the second rotating shaft 220 can be reasonably set based on actual selection.

[0046] like Figure 2 As shown, in some embodiments, a first anti-rotation member 120 is sleeved on the first rotating shaft 110 and is kept in a relatively stationary state therewith. The first anti-rotation member 120 is configured with a first anti-rotation portion 130 bent toward the second rotating member 30. An arc-shaped channel 360 is configured on the second rotating member 30. The arc-shaped channel 360 is co-centered with the second connecting hole 310. The first anti-rotation portion 130 is slidably connected in the arc-shaped channel 360.

[0047] It can be understood that, since the first stopper 120 will not move relative to the first rotating shaft 110 after being sleeved on the first rotating shaft 110, the first stopper 130 is in a stationary state relative to the first rotating shaft 110. Since the first stopper 130 is slidably connected in the arc channel 360 of the second rotating member 30, when the first rotating member 20 and the second rotating member 30 rotate around the first rotating shaft 110, the first stopper 130 can slide in the arc channel 360. When the first stopper 130 abuts against the end of the arc channel 360, the maximum rotation angle of the first rotation direction is limited.

[0048] Specifically, the arc-shaped channel 360 has a first end and a second end that are far away from each other. When the first rotation-stopping portion 130 slides to abut against the first end, the maximum rotation angle of the first rotation direction in the clockwise direction is limited. When the first rotation-stopping portion 130 slides to abut against the second end, the maximum rotation angle of the first rotation direction in the counterclockwise direction is limited.

[0049] In some embodiments, the first stopper 130 can be configured to be arc-shaped, and the centers of the first stopper 130, the arc-shaped channel 360, and the second connecting hole 310 are located on the same axis. The radius of the first stopper 130 and the radius of the arc-shaped channel 360 can be the same. The arc length of the first stopper 130 is smaller than the arc length of the arc-shaped channel 360. Thus, it is ensured that the first stopper 130 can be slidably installed in the arc-shaped channel 360 and can slide a certain distance in the arc-shaped channel 360.

[0050] In some embodiments, the first anti-rotation portion 130 can also be set to be straight. In this case, the arc-shaped channel 360 can have a certain width, and the first anti-rotation portion 130 can also slide a certain distance in the arc-shaped channel 360.

[0051] The first anti-rotation member 120 and the first rotating shaft 110 remain in a relatively static state, which means that after the first anti-rotation member 120 is sleeved on the first rotating shaft 110, the two do not rotate relative to each other.

[0052] In some embodiments, the first rotation stopper 120 may be located between the first rotating member 20 and the second rotating member 30. The first rotation stopper 120 may also be located on a side of the second rotating member 30 away from the first rotating member 20.

[0053] Please continue reading Figure 2 In some embodiments, the first stopper 120 is configured with a first mounting hole 140. The first mounting hole 140 is sleeved on the first rotating shaft 110. In the circumferential direction of the first rotating shaft 110, the first rotating shaft 110 has a first arc segment 1110 and a first flat segment 1120. The first mounting hole 140 has a first arc-shaped hole wall surface 1410 corresponding to the first arc segment 1110 and a first straight hole wall surface 1420 corresponding to the first flat segment 1120.

[0054] The first mounting hole 140 is constructed on the first stopper 120 so that the first stopper 120 can be sleeved on the first rotating shaft 110. Based on the first rotating shaft 110 having the first arc segment 1110 and the first flat segment 1120, and the first mounting hole 140 having the first arc hole wall surface 1410 and the first straight hole wall surface 1420. When the first stopper 120 is sleeved on the first rotating shaft 110, the first arc hole wall surface 1410 is in contact with the first arc segment 1110, and the first straight hole wall surface 1420 is in contact with the first flat segment 1120. Therefore, based on the mutual cooperation between the first straight hole wall surface 1420 and the first flat segment 1120, the first stopper 120 cannot rotate around the first rotating shaft 110.

[0055] The first arc segment 1110 and the first flat segment 1120 can each be provided with two, and the first arc segment 1110 and the first flat end are alternately connected. Of course, the first arc segment 1110 and the first flat segment 1120 can also be provided with multiple, and multiple first arc segments 1110 and the first flat end are alternately connected. The number of the first arc hole wall surface 1410 and the first straight hole wall surface 1420 of the first mounting hole 140 is adapted to the first arc segment 1110 and the first flat segment 1120.

[0056] In some embodiments, a first groove extending along the axial direction of the first rotating shaft 110 can also be constructed. A first protrusion is set in the first mounting hole 140. When the first anti-rotation member 120 is sleeved on the first rotating shaft 110, the first protrusion is engaged in the first groove. Therefore, the first anti-rotation member 120 and the first rotating shaft 110 are relatively stationary and do not rotate by the cooperation of the first protrusion and the first groove.

[0057] like Figure 2As shown, in some embodiments, the free end of the first rotating shaft 110 passes through the second connecting hole 310 and is connected to the first fastener 150. A first washer 160 is sleeved on the first rotating shaft 110. The first washer 160 is located between the first fastener 150 and the second rotating member 30. The first washer 160 is a flexible washer. The first washer 160 is configured to deform under the action of the first fastener 150 to adjust the tightness between the first fastener 150 and the second rotating member 30.

[0058] It is understandable that when the first fastener 150 moves toward the direction close to the second rotating member 30, the first washer 160 will be compressed, so that the first fastener 150, the second rotating member 30, the first rotating member 20 and the first rotating shaft 110 are assembled more tightly. At this time, a larger external force is required to make the first rotating member 20 and the second rotating member 30 rotate around the first rotating shaft 110, so that the stability of the first rotating member 20 and the second rotating member 30 is better, but the rotation is more difficult. When the first fastener 150 moves toward the direction away from the second rotating member 30, the first washer 160 will be released, so that the assembly between the first fastener 150, the second rotating member 30, the first rotating member 20 and the first rotating shaft 110 is loosened. At this time, the first rotating member 20 and the second rotating member 30 can be rotated around the first rotating shaft 110 under a smaller external force, so that the first rotating member 20 and the second rotating member 30 can be easily rotated, but the stability is relatively poor.

[0059] Therefore, during assembly, the installation position of the first fastener 150 can be reasonably selected based on actual use conditions, so that the first fastener 150, the second rotating member 30, the first rotating part and the first rotating shaft 110 have appropriate tightness, so that the first rotating member 20 and the second rotating member 30 can rotate around the first rotating shaft 110 under appropriate force, and have a certain self-positioning ability after the rotation is completed.

[0060] The first fastener 150 is a fastening nut, and an end of the first rotating shaft 110 away from the fixing member 10 is configured with an external thread. The first fastener 150 is threadedly connected to the external thread section of the first rotating shaft 110. In addition, after the installation position of the first fastener 150 is determined, the first fastener 150 and the first rotating shaft 110 can be bonded with an adhesive to prevent the first fastener 150 from falling off the first rotating shaft 110.

[0061] The free end of the first rotating shaft 110 is an end of the first rotating shaft 110 away from the fixing member 10. The first washer 160 is a conical flexible washer.

[0062] In some embodiments, the number of the first washers 160 can be two, and the two first washers 160 are stacked along the first direction. Of course, the number of the first washers 160 can also be multiple, and the multiple first washers 160 are stacked along the first direction.

[0063] like Figure 2 and Figure 4 As shown, in some embodiments, the second rotating member 30 is configured with a connecting portion 330 bent toward the first rotating member 20. The third connecting hole 320 is configured in the connecting portion 330.

[0064] The third connection hole 320 is configured on the connection portion 330 so that the third connection hole 320 and the second connection hole 310 are located at different positions.

[0065] The connecting portion 330 may be integrally formed with the second rotating member 30 .

[0066] like Figure 3 As shown, in some embodiments, a second anti-rotation member 240 is sleeved on the second rotating shaft 220 and is kept in a relatively static state therewith. The second anti-rotation member 240 is configured with a second anti-rotation portion 250 bent toward the connecting portion 330. An arc-shaped notch 340 is configured on the connecting portion 330. The arc-shaped notch 340 is co-centered with the third connecting hole 320. The second anti-rotation portion 250 is slidably connected in the arc-shaped notch 340.

[0067] It can be understood that, since the second anti-rotation member 240 will not move relative to the second rotating shaft 220 after being sleeved on the second rotating shaft 220, the second anti-rotation portion 250 is in a stationary state relative to the second rotating shaft 220. Since the second anti-rotation portion 250 is slidably connected in the arc-shaped notch 340 of the connecting portion 330, when the second rotating member 30 rotates around the second rotating shaft 220, the second anti-rotation portion 250 can slide in the arc-shaped notch 340. When the second anti-rotation portion 250 abuts against the end of the arc-shaped notch 340, the maximum rotation angle in the first rotation direction is limited.

[0068] Specifically, the arc-shaped notch 340 has a third end and a fourth end that are far away from each other. When the second anti-rotation portion 250 slides to abut against the third end, the maximum rotation angle of the second rotation direction in the clockwise direction is limited. When the second anti-rotation portion 250 slides to abut against the fourth end, the maximum rotation angle of the second rotation direction in the counterclockwise direction is limited.

[0069] In some embodiments, the second stopper 250 can be configured to be arc-shaped, and the centers of the second stopper 250, the arc-shaped notch 340, and the second connecting hole 310 are located on the same axis. The radius of the second stopper 250 and the radius of the arc-shaped notch 340 can be the same. The arc length of the second stopper 250 is smaller than the arc length of the arc-shaped notch 340. Thus, it is ensured that the second stopper 250 can be slidably installed in the arc-shaped notch 340 and can slide a certain distance in the arc-shaped notch 340.

[0070] In some embodiments, the second anti-rotation portion 250 can also be set to be straight. In this case, the arc-shaped gap 340 can have a certain width, and the second anti-rotation portion 250 can also slide a certain distance in the arc-shaped gap 340.

[0071] The second anti-rotation member 240 and the second rotating shaft 220 remain in a relatively static state, which means that after the second anti-rotation member 240 is sleeved on the second rotating shaft 220, the two do not rotate relative to each other.

[0072] In some embodiments, the second rotation stopper 240 may be located between the first rotating member 20 and the connection. The second rotation stopper 240 may also be located on a side of the connection portion 330 away from the first rotating member 20.

[0073] like Figure 2 and Figure 4 As shown, in some embodiments, the second rotation stop 240 is configured with a second mounting hole 260. The second mounting hole 260 is sleeved on the second rotating shaft 220. Wherein, along the circumference of the second rotating shaft 220, the second rotating shaft 220 has a second arc segment 2210 and a second flat segment 2220. The second mounting hole 260 has a second arc-shaped hole wall surface 2610 corresponding to the second arc segment 2210 and a second straight hole wall surface 2620 corresponding to the second flat segment 2220.

[0074] The second mounting hole 260 is configured on the second stopper 240 so that the second stopper 240 can be sleeved on the second rotating shaft 220. Based on the second rotating shaft 220 having the second arc segment 2210 and the second flat segment 2220, and the second mounting hole 260 having the second arc hole wall surface 2610 and the second straight hole wall surface 2620. When the second stopper 240 is sleeved on the second rotating shaft 220, the second arc hole wall surface 2610 is in contact with the second arc segment 2210, and the second straight hole wall surface 2620 is in contact with the second flat segment 2220. Therefore, based on the mutual cooperation between the second straight hole wall surface 2620 and the second flat segment 2220, the second stopper 240 cannot rotate around the second rotating shaft 220.

[0075] The number of the second arc segment 2210 and the second flat segment 2220 can be two, and the second arc segment 2210 and the second flat end are connected alternately. Of course, the number of the second arc segment 2210 and the second flat segment 2220 can also be multiple, and the multiple second arc segments 2210 and the second flat end are connected alternately. The number of the second arc hole wall surface 2610 and the second straight hole wall surface 2620 of the second mounting hole 260 matches the number of the second arc segment 2210 and the second flat segment 2220.

[0076] In some embodiments, a second groove extending along the axial direction of the second rotating shaft 220 may be formed. A second protrusion is provided in the second mounting hole 260. When the second anti-rotation member 240 is sleeved on the second rotating shaft 220, the second protrusion is engaged in the second groove. Thus, the second anti-rotation member 240 and the second rotating shaft 220 are relatively stationary and do not rotate by the cooperation between the second protrusion and the second groove.

[0077] like Figure 3 As shown, in some embodiments, the free end of the second rotating shaft 220 passes through the third connecting hole 320 and is connected to the second fastener 270. A second washer 280 is sleeved on the second rotating shaft 220. The second washer 280 is located between the second fastener 270 and the connecting portion 330. The second washer 280 is a flexible washer. The second washer 280 is configured to deform under the action of the second fastener 270 to adjust the tightness between the second fastener 270 and the connecting portion 330.

[0078] It is understandable that when the second fastener 270 moves toward the direction close to the connecting portion 330, the second washer 280 will be compressed, so that the assembly between the second fastener 270, the connecting portion 330 and the first rotating shaft 110 is tighter. At this time, a larger external force is required to make the second rotating member 30 rotate around the second rotating shaft 220, so that the stability of the second rotating member 30 is better, but the rotation is more difficult. When the second fastener 270 moves in the direction away from the connecting portion 330, the second washer 280 will be released, so that the assembly between the second fastener 270, the connecting portion 330 and the first rotating shaft 110 is looser. At this time, the second rotating member 30 can be rotated around the second rotating shaft 220 under a smaller external force, so that the second rotating member 30 can be easily rotated, but the stability is relatively poor.

[0079] Therefore, during assembly, the installation position of the second fastener 270 can be reasonably selected based on actual use conditions, so that the second fastener 270, the connecting portion 330 and the second rotating shaft 220 have appropriate tightness, so that the second rotating member 30 can rotate around the second rotating shaft 220 under appropriate force, and has a certain self-positioning ability after the rotation is completed.

[0080] The second fastener 270 is a fastening nut, and an end of the second rotating shaft 220 away from the first rotating member 20 is configured with an external thread. The second fastener 270 is threadedly connected to the external thread section of the second rotating shaft 220. In addition, after the installation position of the second fastener 270 is determined, the second fastener 270 and the second rotating shaft 220 can be bonded by an adhesive to prevent the second fastener 270 from falling off the second rotating shaft 220.

[0081] The free end of the second rotating shaft 220 is an end of the second rotating shaft 220 away from the first rotating member 20. The second washer 280 is a conical flexible washer.

[0082] In some embodiments, the number of the second washers 280 can be set to two, and the two second washers 280 are stacked along the second direction. Of course, the number of the second washers 280 can also be set to multiple, and multiple second washers 280 are stacked along the second direction.

[0083] like Figure 3 and Figure 4 As shown, in some embodiments, a slot 350 is formed on the connecting portion 330. A third washer 290 is also sleeved on the second rotating shaft 220. The third washer 290 is configured with a limiting portion 2910 bent toward the connecting portion 330. The limiting portion 2910 is locked in the slot 350.

[0084] It is understandable that after the limiting portion 2910 of the third washer 290 is engaged with the slot 350 of the connecting portion 330 , the third washer 290 cannot rotate around the second rotating shaft 220 , which facilitates the positioning and installation of the third washer 290 .

[0085] Two third washers 290 may be sleeved on each second rotating shaft 220. One of the third washers 290 is located on a side of the connecting portion 330 close to the first rotating member 20, and the other third washers 290 is located on a side of the connecting portion 330 away from the first connecting portion 330. The limiting portions 2910 of the two third washers 290 extend toward each other, and are engaged in the slot 350 of the same connecting portion 330 after being sleeved on the second rotating shaft 220.

[0086] The size of the limiting portion 2910 is the same as that of the slot 350 , so that the limiting portion 2910 and the slot 350 cooperate to prevent rotation, thereby facilitating the fixing of the position of the third gasket 290 .

[0087] like Figure 4 As shown, in some embodiments, two connecting parts 330 are arranged at intervals. Each connecting part 330 is configured with a second connecting hole 310. Two opposite sides of the first rotating member 20 are respectively configured with a second rotating shaft 220. Each second rotating shaft 220 is rotatably connected in a second connecting hole 310.

[0088] Two connecting parts 330 are spaced apart on the second rotating member 30 to respectively connect a second rotating shaft 220 on two opposite sides of the first rotating member 20. Thus, the stability and reliability of the second rotating member 30 during rotation are ensured.

[0089] like Figure 6 As shown, the embodiment of the present application further provides a bracket assembly. The bracket assembly includes a bracket body 40 and a rotating mechanism as in the above-mentioned embodiment. The bracket body 40 is configured with an installation channel 410. The fixing member 10 is installed in the installation channel 410.

[0090] In some embodiments, the first rotating member 20 is rotatably mounted on the first rotating shaft 110 of the fixed member 10, and the second rotating member 30 is rotatably mounted on the second rotating shaft 220 of the first rotating member 20, so that the first rotating member 20 and the second rotating member 30 can rotate around the first rotating shaft 110, and the second rotating member 30 can rotate around the second rotating shaft 220, so that the second rotating member 30 can be adjusted in two directions. Since the aperture of the second connecting hole 310 is larger than the diameter of the first rotating shaft 110, when the second rotating member 30 rotates around the second rotating shaft 220, the first rotating shaft 110 can rotate to a certain extent in the second connecting hole 310 to prevent the first rotating shaft 110 from interfering with the rotation of the second rotating member 30 around the second rotating shaft 220. Based on the above installation method, the first rotating member 20 and the second rotating member 30 can be both installed on the fixed member 10, so that the structure of the rotating mechanism is compact and occupies less installation space.

[0091] The upper surface and / or the lower surface of the frame 40 are configured with fastening holes connected to the installation channel 410. The fixing member 10 is configured with a threaded hole. When the fixing member 10 is arranged in the installation channel 410, the fastening hole is connected to the threaded hole. Bolts are sequentially inserted into the fastening hole and the threaded hole to achieve the position fixation between the fixing member 10 and the frame 40.

[0092] In some embodiments, the installation channel 410 can be configured as a square channel, and the fixing member 10 is a square fixing member 10 .

[0093] like Figures 5 to 7 As shown, the embodiment of the present application also provides a display. The display includes a rear cover 50 and a bracket assembly as in the above-mentioned embodiment. The rear cover 50 is configured with a through hole 510. A mounting portion 420 is configured on the frame 40. The mounting channel 410 is configured on the mounting portion 420. The mounting portion 420 passes through the through hole 510 from the rear side of the rear cover 50 so that the rotating mechanism is located at the front side of the rear cover 50. The second rotating member 30 is fixedly connected to the rear cover 50.

[0094] In some embodiments, the first rotating member 20 is rotatably mounted on the first rotating shaft 110 of the fixed member 10, and the second rotating member 30 is rotatably mounted on the second rotating shaft 220 of the first rotating member 20, so that the first rotating member 20 and the second rotating member 30 can rotate around the first rotating shaft 110, and the second rotating member 30 can rotate around the second rotating shaft 220, so that the second rotating member 30 can be adjusted in two directions. Since the aperture of the second connecting hole 310 is larger than the diameter of the first rotating shaft 110, when the second rotating member 30 rotates around the second rotating shaft 220, the first rotating shaft 110 can rotate to a certain extent in the second connecting hole 310 to prevent the first rotating shaft 110 from interfering with the rotation of the second rotating member 30 around the second rotating shaft 220. Based on the above installation method, the first rotating member 20 and the second rotating member 30 can be both installed on the fixed member 10, so that the structure of the rotating mechanism is compact and occupies less installation space.

[0095] Based on the through hole 510 constructed on the back cover 50, after the mounting portion 420 of the frame 40 is inserted into the through hole 510, the rotating mechanism can be located at the front side of the back cover 50. When the screen is mounted on the back cover 50, the rotating mechanism can be built into the display. Based on the good compactness of the rotating mechanism and the small installation space occupied, the rotating mechanism is built into the display, which can protect the rotating mechanism on the one hand and improve the aesthetics of the display on the other hand.

[0096] The second rotating member 30 is fixedly connected to the back cover 50. When the second rotating member 30 and the first rotating member 20 rotate around the first rotating shaft 110, the back cover 50 can be rotated along the first rotation direction to achieve the angle adjustment of the display in the up-down direction. When the second rotating member 30 rotates around the second rotating shaft 220, the back cover 50 can be rotated along the second rotation direction to achieve the angle adjustment of the display in the front-back direction.

[0097] Specifically, a plurality of connecting posts are formed on the back cover 50. A plurality of assembly holes corresponding to the connecting posts are formed on the second rotating member 30. The connecting posts are connected to the assembly holes correspondingly and locked by a fastening mechanism, thereby realizing reliable fixation of the second rotating member 30 and the connecting posts.

[0098] In some embodiments, a support member 520 is configured on the back cover 50. A support groove 530 is formed on the support member 520. The support groove 530 is communicated with the through hole 510. The first rotating member 20 is connected in the support groove 530.

[0099] It can be understood that the support member 520 can support the first rotating member 20. The support groove 530 can be configured as an arc groove, and the cylindrical area of ​​the first rotating member 20 can match the arc groove.
