At this time, the use angle of the upper pin shaft can be changed by flipping the upper pin shaft. Driving the support to rotate in the installation groove by rotating the upper pin shaft realizes the full-angle adjustment of the upper pin shaft. When the hole positions of the two parts do not correspond, by adjusting the angle of the upper pin shaft, it can be inserted into the holes of the parts, realizing the connection of the two parts, and further improving its use effect.

However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily making these embodiments difficult to understand. Additionally, all embodiments can be used in combination with each other.

[0034] Please refer to Figures 1 to 8 , the present invention provides a technical solution: a pin shaft that can be adjusted at all angles;

[0035] Embodiment 1:

[0036] In order to improve the usage effect of the upper pin shaft 1 and the lower pin shaft 7, a connecting groove 12 is provided on the surface of the lower pin shaft 7, and a connecting block 11 is provided on the surface of the cylinder column 5. The connecting block 11 is arranged in the connecting groove 12, and the two are rotatably connected. The upper pin shaft 1 is arranged above the cylinder column 5. When the adjacent end faces of the upper pin shaft 1, the cylinder column 5, and the lower pin shaft 7 abut against each other, it is in its initial state. The two are locked by inserting two split pins into the pin holes provided at the outer ends of the upper pin shaft 1 and the lower pin shaft 7, and are used as traditional pin shafts. When the two parts are in a parallel state and allow the pin shaft to be inserted, if the insertion direction of the pin holes of the upper pin shaft 1 and the lower pin shaft 7 is limited by the peripheral devices of the parts, the split pins for locking cannot be inserted into the pin holes. At this time, just rotate the upper pin shaft 1 and the lower pin shaft 7 to make the connecting block 11 rotate in the connecting groove 12, so as to change the orientation angle of the pin holes at their ends, avoid the limitation of the pin hole insertion direction, and facilitate the insertion of the split pins, thereby improving their usage effect.

[0037] Embodiment Two:

[0038] On the basis of Embodiment One, in order to improve the usage effect of the upper pin shaft 1, an adjustment groove 9 is provided on the surface of the cylinder column 5. The surface of the adjustment groove 9 is provided with internal threads 16, and an adjustment column 4 is arranged in the adjustment groove 9. The surface of the adjustment column 4 is provided with a thread groove 14 and an internal screw hole 20. An installation groove 15 is provided on the surface of the thread groove 14, and a support 17 is arranged in the installation groove 15. An external screw hole 21 is provided on the outer side of the surface of the cylinder column 5, and the external screw hole 21 communicates with the inside of the cylinder column 5. A screw 6 is screwed in the external screw hole 21. Two sides of the surface of the adjustment groove 9 are symmetrically provided with sliding grooves 10. Two sides of the bottom surface of the adjustment column 4 are symmetrically fixed with limit blocks 8. The limit blocks 8 are arranged in the sliding grooves 10, and the two are slidably connected. A threaded column 2 is provided on the surface of the upper pin shaft 1, and the threaded column 2 is in threaded connection with the internal threads 16. By loosening the screw 6 so that its inner end disengages from the internal screw hole 20, the fixation of the adjustment column 4 can be released. The adjustment column 4 is arranged in the sliding groove 10 through the limit blocks 8 to ensure its stability and prevent the adjustment column 4 from rotating on its own, so that it can only move up and down in the adjustment groove 9. Then rotate the upper pin shaft 1 to move the threaded column 2 above the cylinder column 5. When the upper pin shaft 1 rotates, the support 17 rotates in the installation groove 15. Therefore, the rotation of the upper pin shaft 1 is not limited by the adjustment column 4. By pulling the upper pin shaft 1 to drive the adjustment column 4 to move upward, after it moves to a suitable height, the screw 6 is screwed into the corresponding internal screw hole 20 to fix the adjustment column 4. Multiple internal screw holes 20 are provided, realizing effective adjustment of the upper pin shaft 1 at different heights, so that it can be adapted to parts with different spacing heights for use.

[0039] Embodiment Three:

[0040] On the basis of the second embodiment, in order to improve the usage effect of the upper pin shaft 1, a threaded plate 19 is provided on the surface of the threaded column 2, and a hinge groove 3 is formed on the surface of the threaded column 2. A hinge rod 13 is provided on the surface of the hinge groove 3. A limit groove 18 is formed on the surface of the support 17. The threaded plate 19 corresponds to the threaded groove 14, and the threaded plate 19 and the threaded groove 14 are in threaded connection. The hinge rod 13 is arranged in the limit groove 18. By rotating the upper pin shaft 1, the threaded plate 19 is moved out of the threaded groove 14 to release the locking of the threaded column 2. The depth of the installation groove 15 is greater than the thickness of the bottom of the support 17, so it does not affect the threaded plate 19 moving out of the threaded groove 14. At this time, the usage angle of the upper pin shaft 1 can be changed by flipping the upper pin shaft 1. By rotating the upper pin shaft 1, the support 17 is driven to rotate in the installation groove 15 to realize the full-angle adjustment of the upper pin shaft 1. When the hole positions of the two parts do not correspond, by adjusting the angle of the upper pin shaft 1, it can be inserted into the holes of the parts to realize the connection of the two parts, thereby improving its usage effect.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
