The elastic component 80' provides a force to compress the second beveled locking plate 50, causing it to engage the beveled teeth 16'.

[0071] The fixed shaft 90 is disposed within the circular passage 18 of the rotating shaft 20 along a first direction D1 and is rotatable within the circular passage 18. Two elastic components 80 can be sleeved on both ends of the fixed shaft 90 along the first direction D1.

In this embodiment, the two fixing components 98 and 98' can be screws.

[0074] In this embodiment, one end of a fixing rod 96 is disposed on the first locking rod 92. A polygonal projection is provided at the location where the fixing rod 96 connects to the first locking rod 92, which can be correspondingly engaged with a polygonal groove on the first locking rod 92. When the fixing rod 96 rotates, the first locking rod 92 is driven to rotate relative to the rotating shaft 10. One end of a fixing rod 96' is disposed on the second locking rod 94. A polygonal projection is provided at the location where the fixing rod 96 connects to the second locking rod 94, which can be correspondingly engaged with a polygonal groove on the second locking rod 94. When the fixing rod 96 rotates, the second locking rod 94 is driven to rotate relative to the rotating shaft 10.

[0075] To better understand the assembly state of this embodiment, a central axis AX1 is drawn at the center of the rotating shaft 20, parallel to the first direction D1. The central axis AX1 passes through the centers of the rotating shaft 10, the inner sleeve 20, the outer sleeve 30, the first through-hole 42, the first opening 64, the second opening 74, the elastic elements 80 and 80', the fixed shaft 90, the first locking rod 92, and the second locking rod 94. The first locking rod 92, the fixed rod 96, the second locking rod 94, and the fixed rod 96' are rotatable about the central axis AX1.

[0076] The fixing assembly 98 is sequentially provided with a fixing rod 96 and a first locking rod 92 along the central axis AX1 for mounting on the rotating shaft 10. The fixing assembly 98' is sequentially provided with a fixing rod 96' and a second locking rod 94 along the central axis AX1 for mounting on the rotating shaft 10. The central axis AX1 passes through the centers of the fixing assembly 98, the first locking rod 92, the fixing assembly 98', and the second locking rod 94.

[0077] The first beveled locking piece 40, the elastic component 80, the first pressing cap 60, the first locking rod 92, and the fixing rods 96 and 98 disposed at the first end 12 of the rotating shaft 10 are arranged in order from the first end 12 outward along the first direction D1. The second beveled locking piece 50, the elastic component 80', the second pressing cap 70, the second locking rod 94, the fixing rod 96', and the fixing assembly 98' disposed at the second end 14 of the rotating shaft 10 are arranged in order from the second end 14 outward along the first direction D1.

[0078] After explaining the structure of the pivot shaft device 1, please refer to Figure 6 、 Figure 7 and Figure 8 , to illustrate the usage status. In this embodiment, when the device angle needs to be adjusted, please refer to Figure 6 , press the first pressing cap 60 and the second pressing cap 70 at the same time. Figure 7 As shown, when the first pressing cap 60 is pressed, the first extrusion columns 62, 62' of the first pressing cap 60 will pass through the first arc-shaped through-holes 44, 44' to push the inner sleeve 20 so that the inner sleeve 20 slides relative to the outer sleeve 30 along the first direction D1. Figure 8 After the inner sleeve 20 slides in the first direction D1, it pushes the second beveled tooth locking plate 50, separating the second beveled tooth locking plate 50 from the beveled teeth 16', allowing the beveled teeth 16' to rotate relative to the second beveled tooth locking plate 50. When the second beveled tooth locking plate 50 is separated from the beveled teeth 16', the rotating shaft 10 can rotate relative to the second beveled tooth locking plate 50, and at the same time, the rotating shaft 10 can rotate relative to the second locking rod 94 and the fixed rod 96'.

[0079] Please refer to Figure 8When the second pressing cap 70 is pressed, the second squeezing columns 72, 72' of the second pressing cap 70 pass through the second arc-shaped through-holes 54, 54' to push the outer sleeve 30, and the outer sleeve 30 slides relative to the inner sleeve 20 along the first direction D1. Figure 7 After the outer sleeve 30 slides in the first direction D1, it pushes the first beveled tooth locking plate 40, causing it to separate from the beveled teeth 16, allowing the beveled teeth 16 to rotate relative to the first beveled tooth locking plate 40. When the first beveled tooth locking plate 40 separates from the beveled teeth 16, the rotating shaft 10 can rotate relative to the first beveled tooth locking plate 40, and the rotating shaft 10 can also rotate relative to the first locking rod 92 and the fixed rod 96. When the second beveled tooth locking plate 50 separates from the beveled teeth 16, and the first beveled tooth locking plate 40 separates from the beveled teeth 16, the rotating shaft 10 and the device 2 fixed to the rotating shaft 10 can rotate relative to the fixed rods 96 and 96'.

[0080] When the user adjusts the device to the desired angle and wishes to secure it, they release the first and second push caps 60 and 70. The elastic force of the resilient elements 80 and 80' then compresses the first and second beveled locking tabs 40 and 50, causing the first beveled locking tab 40 to engage with the beveled teeth 16, and the second beveled locking tab 50 to engage with the beveled teeth 16'. The first and second beveled locking tabs 40 and 50 now prevent the first locking rod 92, the fixing rod 96, and the second locking rod 94 and fixing rod 96' from rotating relative to the shaft 10, effectively securing the rotation angle of the device 2.

[0081] In summary, the present invention is easy to operate, can quickly and easily adjust the angle of the device, and has good fixing and angle positioning effects.

[0082] In summary, this invention meets the requirements for invention patents, and a patent application is hereby filed in accordance with the law. However, the foregoing description is merely a preferred embodiment of the invention, and the scope of the invention is not limited to the foregoing embodiment. Any equivalent modifications or variations made by persons skilled in the art in accordance with the spirit of the invention are intended to be encompassed by the following patent application.
