The multi-degree-of-freedom rotating shaft enables users to rotate, tilt or adjust in multiple directions, thus enhancing the flexibility of operation. This allows users to more freely control and adjust the position, direction and angle of computer devices or components to obtain a more comfortable operation experience that meets personal needs. The application of multi-degree-of-freedom rotating shafts can expand the functions of computer devices. By using a rotating shaft, new operation modes and functions can be added to the device, such as rotating the view angle, adjusting parameters, selecting options, etc. The multi-degree-of-freedom rotating shaft in a computer can increase the flexibility of operation, expand function integration, support multi-dimensional interaction and improve the human-machine interface design.

[0003] When the existing multi-degree-of-freedom rotating shafts are in use, they generally can only rotate in one direction, and the scope of use is relatively limited, unable to meet the needs of more computers. In addition, when the existing multi-degree-of-freedom rotating shafts are in use, due to the lack of dust and water protection settings, during the daily use of the computer, the inside of the multi-degree-of-freedom rotating shaft may be unable to work properly due to dust or water sources, and then it needs to be replaced. Therefore, it is necessary to provide a multi-degree-of-freedom rotating shaft to solve the above technical problems. Summary of the Utility Model

Detailed implementation manners

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0024] Please refer to Figures 1-4 , a multi-degree-of-freedom rotating shaft. As a further technical solution proposed by the present utility model, it includes: a rotating sleeve block 1, a fixed plate 2 is arranged on the lower surface of the rotating sleeve block 1, a rotating block 3 is arranged inside the rotating sleeve block 1, and a protective pad 4 is arranged on the outer surface of the rotating block 3. A plurality of groups of clamping rods 5 are evenly arranged at the lower end of the rotating block 3. The upper end of the rotating block 3 is connected to the lower surface of the first connecting plate 6. Two groups of connecting blocks 7 are symmetrically arranged on the upper surface of the first connecting plate 6. A clamping block 8 is inserted into each of the two groups of connecting blocks 7. A plurality of groups of clamping rings 9 are evenly sleeved on the outside of the clamping block 8. Nuts 10 are sleeved on the outer ends of the two groups of clamping blocks 8. Protective sleeves 11 are sleeved on the outside of the two groups of nuts 10;

[0025] A second connecting plate 12, the lower surface of the second connecting plate 12 is connected to the two groups of connecting blocks 7. Two groups of connecting blocks 13 are symmetrically arranged on the lower surface of the second connecting plate 12. A connecting rod 14 is arranged between the two groups of connecting blocks 13. A sleeve 15 is sleeved on the outside of the connecting rod 14. A plurality of groups of clamping strips 16 are evenly arranged on the inner wall of the sleeve 15. The outer surface of the sleeve 15 is connected to the lower end of the moving block 17. The moving block 17 is connected to the lower surface of the mounting plate 18.

[0026] Specifically, a groove is formed inside the rotating sleeve block 1, and a plurality of groups of slots corresponding to the clamping rods 5 are evenly arranged on the inner wall of the bottom end of the groove. Through the arrangement of the plurality of groups of slots, the rotating block 3 can be fixed in the groove inside the rotating sleeve block 1 through the plurality of groups of clamping rods 5.

[0027] Specifically, a plurality of groups of mounting holes are evenly formed on the fixed plate 2. Through the arrangement of the plurality of groups of mounting holes, the fixed plate 2 can be fixedly installed on the required equipment.

[0028] Specifically, the rotating block 3 is movably inserted into the groove inside the rotating sleeve block 1. By rotating the rotating block 3 in the groove inside the rotating sleeve block 1, the multi-degree-of-freedom rotating shaft can start to rotate in the X-axis direction.

[0029] Specifically, one end of each of the two sets of clamping blocks 8 is provided with a thread corresponding to the nut 10. Three sets of clamping rings 9 and two sets of connecting blocks 7 are sleeved outside the two sets of clamping blocks 8. The three sets of clamping rings 9 and the two sets of connecting blocks 7 are distributed at intervals outside the nut 10 in sequence. By clamping the clamping rings 9 between and outside the two sets of connecting blocks 7, the two sets of connecting blocks 7 can be kept stable after rotation.

[0030] Specifically, the sleeve 15 is movably sleeved outside the connecting rod 14. By starting to rotate the sleeve 15 on the connecting rod 14, the moving block 17 can start to rotate.

[0031] Specifically, the multiple sets of clamping rings 9 and the clamping strips 16 are both made of rubber material. Since the clamping rings 9 and the clamping strips 16 are both made of rubber material, when the clamping rings 9 and the clamping strips 16 are subjected to external pressure, they will deform, and further, the positions of the connecting block 7 or the connecting rod 14 can be fixed.

[0032] Specifically, four mounting holes are uniformly arranged on the mounting plate 18. Through the arrangement of the multiple mounting holes, the mounting plate 18 can be fixedly installed on the required equipment.

[0033] Working principle: When using a multi-degree-of-freedom rotating shaft, first, the fixing plate 2 and the mounting plate 18 are respectively fixedly installed on different connecting devices through the mounting holes on the fixing plate 2 and the mounting plate 18. Subsequently, by lifting the rotating block 3 inside the rotating sleeve block 1 upward, when all the multiple sets of clamping rods 5 at the lower end of the rotating block 3 are pulled out from the insertion holes in the inner groove of the rotating sleeve block 1, the rotation of the rotating block 3 in the X-axis direction can be completed. Subsequently, when the multi-degree-of-freedom rotating shaft needs to rotate in the Y-axis direction, only by rotating the connecting block 7 on the two sets of clamping blocks 8 can the operation be completed. Finally, when it is necessary to rotate the multi-degree-of-freedom rotating shaft in the Z-axis direction, only by rotating the moving block 17, the sleeve 15 at the lower end of the moving block 17 can start to rotate on the connecting rod 14. Through the above operations, the multi-degree-of-freedom rotating shaft can rotate at multiple angles. This is the entire working process of a multi-degree-of-freedom rotating shaft.

[0034] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
