[0067] In an embodiment, the universal joint in the spherical universal joint, the T-shaped shaft universal joint or the cross shaft universal joint is provided with damping, so that the spherical universal joint, the T-shaped shaft universal joint and the cross shaft universal joint can be stopped at any position of the universal swing during the universal swing.

[0068] The first connecting arm 10 and the second connecting arm 20 of the embodiment are lifting arms of the same mechanism. The specific structure of the first connecting arm 10 is taken as an example for description.

[0069] Please refer to Figure 7 and Figure 8 The first connecting arm 10 comprises a first connecting seat 11, a second connecting seat 12, a first lifting connecting rod 13, a second lifting connecting rod 14, a third lifting connecting rod 15 and a sliding sleeve 16. The first connecting seat 11 is the first end of the first connecting arm 10, and the second connecting seat 12 is the second end of the first connecting arm 10.

[0070] The two ends of the first lifting connecting rod 13 are rotatably connected to the first connecting seat 11 and the second connecting seat 12 respectively, the two ends of the second lifting connecting rod 14 are rotatably connected to the first connecting seat 11 and the second connecting seat 12 respectively, and the first lifting connecting rod 13 and the second lifting connecting rod 14 are arranged in parallel. The sliding sleeve 16 comprises a sliding block 16a and a friction sleeve 16b. The sliding block 16a is enclosed by four plates and has a hollow structure in the middle. The four surfaces of the sliding block 16a are each provided with a through hole. The friction sleeve 16b is made of rubber or other materials with certain friction. The friction sleeve 16b is fixed between the two opposite through holes of the sliding block 16a by a sleeve ring. The sliding block 16a and the friction sleeve 16b are movably sleeved on the second lifting connecting rod 14 and arranged close to the first connecting seat 11. A certain friction force is generated between the friction sleeve 16b and the second lifting connecting rod 14, which plays a damping role. The third lifting connecting rod 15 has two ends rotatably connected to the first connecting seat 11 and the sliding block 16a respectively. The two third lifting connecting rods 15 are arranged on the two sides of the sliding block 16a. The third lifting connecting rod 15 can be rotatably connected to the first lifting connecting rod 13 on the first connecting seat 11 through the same rotating shaft.

[0071] The lifting damping principle of the embodiment is as follows: when the second connecting seat 12 moves upward, the two ends of the first lifting connecting rod 13 and the second lifting connecting rod 14 are driven to rotate relative to the first connecting seat 11 and the second connecting seat 12 respectively. The first lifting connecting rod 13 and the second lifting connecting rod 14 swing upward with the movement of the second connecting seat 12. After the second lifting connecting rod 14 swings upward, the sliding sleeve 16 is pulled by the third lifting connecting rod 15, so that the sliding sleeve 16 slides relative to the second lifting connecting rod 14 and generates a friction force. After the second connecting seat 12 stays at a certain height and loses the traction force, the second connecting seat 12 and the components connected thereto will generate a downward gravity. The gravity will drive the first lifting connecting rod 13 and the second lifting connecting rod 14 to swing downward. At this time, the sliding sleeve 16 will generate an upward friction force relative to the second lifting connecting rod 14. When the friction force is greater than the gravity generated by the second connecting seat 12 and the components connected thereto, the friction force will play a damping and limiting role. The selection of the friction sleeve 16b capable of generating sufficient friction force can realize the function of stopping at any position. The length and material of the friction sleeve 16b of the embodiment are optimized according to experiments, so that the first connecting arm 10 can be kept stable at any height position.

[0072] In the embodiment, the spring 17 is arranged on the second lifting connecting rod 14. In order to limit the spring 17, the second lifting connecting rod 14 is provided with a baffle 18 at one end close to the second connecting seat 12. The spring 17 is clamped between the baffle 18 and the sliding block 16a. The spring 17 plays a role of buffering and storing energy. During the lifting of the first connecting arm 10, the energy stored by the spring 17 can overcome the friction between the sliding sleeve 16 and the second lifting connecting rod 14, so that the lifting can be driven by a smaller external force, which facilitates the operation of the user. The baffle 18 is also arranged as a nut, and the second lifting connecting rod 14 is provided with a corresponding external thread. The baffle 18 can move along the second lifting connecting rod 14. The movable baffle 18 can adjust the compression amount of the spring 17, so that the tightness of the spring 17 can be adjusted according to the needs to achieve the best lifting movement.

[0073] In order to better protect the first connecting arm 10, the first connecting arm 10 further comprises a shell 19 rotatably connected between the first connecting seat 11 and the second connecting seat 12. The first lifting connecting rod 13, the second lifting connecting rod 14, the third lifting connecting rod 15, the sliding sleeve 16 and the spring 17 are located inside the shell 19. The shell 19 avoids the entanglement of the first connecting arm 10 with external cables during lifting, and also avoids the foreign matter from being stuck in the inside of the first connecting arm 10 to affect the lifting.

[0074] Please refer to Figure 1 and Figure 2 In one embodiment, the floating support device further comprises a connecting piece 70 having a first end and a second end. The first end of the connecting piece 70 is rotatably connected with the second end of the third connecting arm 30 through a first rotating shaft 101, and the first end of the connecting piece 70 is also rotatably connected with the second end of the fourth connecting arm 40 through a second rotating shaft 102. The second end of the connecting piece 70 is rotatably connected with the display 90 through a rotating shaft. The first rotating shaft 101 and the second rotating shaft 102 are arranged side by side in the vertical direction. The rotating shaft connecting the second end of the connecting piece 70 with the display 90 is arranged in the horizontal direction. Thus, the display 90 can pitch and swing relative to the connecting piece 70 through the horizontally arranged rotating shaft. The display 90 and the connecting piece 70 can move together in the horizontal direction through the first rotating shaft 101 and the second rotating shaft 102.

[0075] The connecting piece 70 plays a role of connecting the display 90 and the connecting arm. The connecting piece 70 and the display 90 can also be an integrated structure, or the connecting piece 70 and the display 90 are fixedly connected.

[0076] Please refer to Figure 1 and Figure 2In an embodiment, the floating support device further comprises a mounting base 80, the first end of the first connecting arm 10 is rotatably connected to the mounting base 80 through a third rotating shaft 103, and the first end of the second connecting arm 20 is rotatably connected to the mounting base 80 through a fourth rotating shaft 104. The third rotating shaft 103 and the fourth rotating shaft 104 are arranged side by side in the vertical direction, so that the first connecting arm 10 and the second connecting arm 20 can be horizontally rotated relative to the mounting base 80 through the third rotating shaft 103 and the fourth rotating shaft 104 respectively. The mounting base 80 is used to be mounted on the support device, and the mounting base 80 plays a role of assisting installation.

[0077] In an embodiment, the first rotating shaft 101, the second rotating shaft 102, the third rotating shaft 103 and the fourth rotating shaft 104 are all damping rotating shafts, such as damping rotating shafts with damping springs inside, the two ends of which can rotate relative to each other with damping. The damping rotating shafts are arranged so that the display 90 can be stopped at any position in the rotating range, which is convenient for doctors to operate and use.

[0078] In this embodiment, the floating support device can realize spatial floating through four rotating shafts and two flexible connecting pieces, and the spatial floating is shown as follows:
