[0028] Two card slots 19 are provided on the surface of the rotating shaft 2, and the surface of the mounting groove 9 is plugged with a limit plug handle 17 and a brake plug handle 18, and the brake plug handle 18 is located below the limit plug handle 17, and a rubber gasket 20 is fixed to one end of the brake plug handle 18. The height of the limit sleeve 14 is less than the height of the mounting groove 9, and the distance from the top surface of the limit plug handle 17 to the bottom surface of the brake plug handle 18 is equal to the height difference between the mounting groove 9 and the limit sleeve 14. A rubber ring 15 is fixed on the surface of the mounting groove 9, and the rubber ring 15 is clamped between the limit sleeve 14 and the mounting groove 9 to produce elastic deformation; the surface of the mounting groove 9 has two card slots 19, and the limit plug handle 17 and the brake plug handle 18 are located below the limit plug handle 17, and a rubber gasket 20 is fixed to one end of the brake plug handle 18. The height of the limit sleeve 14 is less than the height of the mounting groove 9, and the distance from the top surface of the limit plug handle 17 to the bottom surface of the brake plug handle 18 is equal to the height difference between the mounting groove 9 and the limit sleeve 14. The surface of the mounting groove 9 has two card slots 19, and the limit plug handle 17 and the brake plug handle 18 are located below the limit plug handle 17, and a rubber gasket 20 is fixed to the bottom surface of the brake plug handle 18, and a rubber gasket 15 is fixed to the surface of the mounting groove 9, and the rubber ring 15 is clamped between the limit sleeve 14 and the mounting groove 9 to produce elastic deformation; the surface of the mounting groove 9 has two card slots 19, and the limit plug handle 17 and the brake plug handle 18 are located below the limit plug handle 17, and a rubber gasket 20 is fixed to the bottom surface of The two groups of sockets 16 are arranged in an upper and lower arrangement, and each group of sockets 16 is provided with a plurality of sockets. The limiting plug handle 17 and the braking plug handle 18 are respectively plugged into the two groups of sockets 16. The top surfaces of one end of the limiting plug handle 17 and the braking plug handle 18 are provided with an inclined surface, and the card groove 19 is an annular groove; the surfaces of the limiting plug handle 17 and the braking plug handle 18 are provided with a through hole 21, and a baffle 22 is inserted into the inside of the through hole 21. The baffle 22 is fixed between two parallel side walls of the socket 16, and a rubber connecting block 23 is fixed on the surface of the baffle 22, and one end of the rubber connecting block 23 is fixed to the surface of the through hole 21.

[0029] When the rotating shaft 2 needs to rotate stably in the connecting seat 1, the limiting sleeve 14 is screwed down along the installation groove 9, and the limiting sleeve 14 pushes the limiting plug handle 17 along the inclined surface. The limiting plug handle 17 tensions the rubber connecting block 23 to produce elastic deformation, and the limiting plug handle 17 is inserted into a card slot 19 on the upper side. However, the limiting plug handle 17 does not clamp the card slot 19. It only realizes that after the limiting plug handle 17 is inserted into the card slot 19, the rotating shaft 2 is prevented from bumping in the connecting seat 1. When the connecting seat 1 and the rotating shaft 2 need to be separated, the limiting sleeve 14 is screwed upwards. After the limiting sleeve 14 and the limiting plug handle 17 are misaligned, the rubber connecting block 23 rebounds and pulls the limiting plug handle 17 back, and the limiting plug handle 17 moves out of the card slot. 19 is disengaged, and the rotating shaft 2 can be pulled out from the connecting seat 1; if it is necessary to brake the rotating shaft 2, continue to screw the limiting sleeve 14 downward, the limiting sleeve 14 pushes the braking handle 18 along the inclined surface, and the braking handle 18 pulls the corresponding rubber connecting block 23 to produce elastic deformation until the braking handle 18 clamps the rubber gasket 20 in a groove 19 on the lower side. In this way, multiple braking handles 18 clamp and brake the rotating shaft 2. When it is necessary to cancel the braking of the rotating shaft 2, just screw the limiting sleeve 14 upward. When the limiting sleeve 14 and the braking handle 18 are misaligned, the rubber connecting block 23 rebounds and pulls the braking handle 18 back, and the braking handle 18 no longer clamps the rotating shaft 2.

[0030] The process of using the rotating connector for wooden furniture is as follows:

[0031] Place the connecting seat 1 on the bottom furniture structure so that the bottom surface of the notch 3 is aligned with the furniture structure. Use a screw to pass through the bolt hole 1 4 to fix the connecting seat 1 to the furniture structure. Properly assemble the guide handle 7 and the bearing 8 of the rotating shaft 2, and ensure that the inner ring of the bearing 8 fits tightly against the guide handle 7. Insert the assembled rotating shaft 2 into the connecting seat 1, and ensure that the rotating shaft 2 can rotate freely. Use another set of screws to pass through the bolt hole 2 6 to fix the rotating shaft 2 to the top furniture structure. Screw the limit sleeve 14 into the installation groove 9, and ensure that the thread sleeve 1 11 and the thread sleeve 2 13 are correctly matched and connected. Adjust the height of the limit sleeve 14 so that it can be freely raised and lowered in the installation groove 9.

[0032] When the rotating shaft 2 needs to rotate stably in the connecting seat 1, screw the limiting sleeve 14 to make it descend along the installation slot 9. The limiting sleeve 14 pushes the limiting handle 17 along the inclined surface, and the limiting handle 17 tensions the rubber connecting block 23 to produce elastic deformation. The limiting handle 17 is inserted into a card slot 19 on the upper side, but does not clamp the card slot 19, and only realizes the limiting effect to prevent the rotating shaft 2 from bumping in the connecting seat 1. When separating the connecting seat 1 and the rotating shaft 2: screw the limiting sleeve 14 upward to misalign the limiting sleeve 14 and the limiting handle 17. The rubber connecting block 23 rebounds and pulls the limiting handle 17 back, and the limiting handle 17 disengages from the card slot 19. At this time, the rotating shaft 2 can be pulled out of the connecting seat 1.

[0033] When the rotating shaft 2 needs to be braked, continue to screw the limit sleeve 14 downward. The limit sleeve 14 pushes the brake plug handle 18 along the inclined surface, and the brake plug handle 18 pulls the corresponding rubber connecting block 23 to produce elastic deformation. Until the brake plug handle 18 clamps the rubber gasket 20 in a slot 19 on the lower side, multiple brake plug handles 18 clamp and brake the rotating shaft 2. When the brake of the rotating shaft 2 is cancelled: screw the limit sleeve 14 upward to misalign the limit sleeve 14 and the brake plug handle 18. The rubber connecting block 23 rebounds and pulls the brake plug handle 18 back, and the brake plug handle 18 no longer clamps the rotating shaft 2, and the brake is cancelled.
