[0022] Please refer to Figure 1-2 , the present utility model provides the following embodiments:

[0023] A high-precision rotating shaft includes: a main shaft rod 1, a bearing seat 2, an adjusting plate frame 3, a fixing plate frame 4, a slider 5, a pressing plate 6, and a driving mechanism. The main shaft rod 1 is installed in the bearing seat 2, and the bearing seat 2 is installed on the top of the adjusting plate frame 3. The adjusting plate frame 3 and the fixing plate frame 4 can be adjusted, so as to realize the height adjustment of the main shaft rod 1. The adjustment operation is convenient, thus meeting the accuracy requirements. In addition, the driving mechanism and the mechanism for locking the state of the main shaft rod 1 are also installed on one side of the adjusting plate frame 3 and can be adjusted together with the adjusting plate frame 3, so as to avoid errors caused by adjustment and ensure accuracy.

[0024] The main shaft rod 1 is installed at the top end of the adjusting plate frame 3 through the bearing seat 2. The main shaft rod 1 is a rotatable shaft member. In this embodiment, the main shaft rod 1 can rotate a certain angle.

[0025] The adjusting plate frame 3 is arranged inside the fixing plate frame 4. A pressing plate 6 is arranged on the outside of the fixing plate frame 4. The adjusting plate frame 3 and the pressing plate 6 are both installed on the slider 5. The slider 5 is slidably installed in the adjusting chute 41 of the fixing plate frame 4. Combining with the accompanying drawings, when adjusting the adjusting plate frame 3 and the fixing plate frame 4, it is necessary to first loosen the fastener, and then adjust the position of the adjusting plate frame 3. During the adjustment process, the slider 5 slides up and down in the adjusting chute 41. After the adjustment is completed, tighten the fastener. The pressing between the pressing plate 6 and the fixing plate frame 4 can also ensure that the slider 5 is not prone to sliding, thereby strengthening the connection stability effect between the adjusting plate frame 3 and the fixing plate frame 4.

[0026] The driving mechanism is used to drive the main shaft rod 1 to rotate and move an angle. The driving mechanism includes a driving component 81. When the driving component 81 shortens, it drives the first connecting block 83 to rotate. The end of the main shaft rod 1 is fixedly connected to the first connecting block 83. Combining with the accompanying drawings, the end of the main shaft rod 1 is a locking end 11, which is coaxial with the main shaft rod 1. The locking end 11 is fixedly connected to one end of the first connecting block 83. When the first connecting block 83 deflects, it drives the locking end 11 to rotate, realizing the rotation of the main shaft rod 1.

[0027] As a preferred solution of the present utility model, a marking arrow is provided on the fixing plate frame 4, and a scale marking is provided on the pressing plate 6. Combining Figure 1, the identification arrow initially points to the 0 mark in the middle part of the pressing plate 6, which can be adjusted as needed. Scale marks are set, enabling quick adjustment and ensuring the accuracy of adjustment. In this embodiment, the smallest scale unit is millimeters.

[0028] As another preferred solution of the present utility model, a fine adjustment limit bolt 7 is provided at the top of the fixed plate frame 4, and the fine adjustment limit bolt 7 extends into the adjustment chute 41. With reference to the attached drawings, specifically, the fine adjustment limit bolt 7 functions as a limit. After the adjustment is completed, the fine adjustment limit bolt 7 should be screwed so that the bottom of the fine adjustment limit bolt 7 is in contact with the upper end of the slider 5 to achieve the limit.

[0029] As another preferred solution of the present utility model, the slider 5 is strip-shaped, and threaded grooves are provided on the slider 5. The pressing plate 6 is connected to the slider 5 through bolts, and the adjusting plate frame 3 is connected to the slider 5 through bolts. The threaded grooves are evenly distributed up and down at equal intervals, and the bolts of the pressing plate 6 and the adjusting plate frame 3 are screwed in at intervals. The pressing between the adjusting plate frame 3 and the pressing plate 6 and the fixed plate frame 4 is separate and will not be affected by each other.

[0030] As another preferred solution of the present utility model, the driving component 81 is installed on the adjusting plate frame 3 through a plate frame. During adjustment, the driving component 81 is driven to adjust together, eliminating the need to change the position of the driving component 81 after adjustment, achieving modular adjustment and simplifying the adjustment operation.

[0031] As another preferred solution of the present utility model, the driving mechanism further includes a connecting seat 82 and a second connecting block 84. The connecting seat 82 is installed at the extended end of the driving component 81, and the first connecting block 83 and the second connecting block 84 are rotatably connected to the connecting seat 82. With reference to the attached drawings, specifically, the first connecting block 83 and the second connecting block 84 are installed on the rotating shaft of the connecting seat 82. During the lifting process of the connecting seat 82, the first connecting block 83 and the second connecting block 84 will be driven to deflect.

[0032] As another preferred solution of the present utility model, a locking mechanism is further included. The locking mechanism includes a locking frame 9 installed on the adjusting plate frame 3. One end of the second connecting block 84 away from the first connecting block 83 is rotatably connected to the locking frame 9. The threaded locking member 10 is screwed to lock the second connecting block 84 and the locking frame 9. Combining the movement process of the second connecting block 84 described above, after the driving component 81 is telescoped, that is, after the complete rotation angle of the main shaft rod 1, the threaded locking member 10 can be screwed to press the end of the second connecting block 84, realizing the locking of the second connecting block 84. In this way, it can be ensured that the second connecting block 84 will no longer rotate, and thus the first connecting block 83 can be kept in a fixed state, and the main shaft rod 1 is in the rotated state.

[0033] All the technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
