[0025] Embodiment 2

[0026] Please refer to Figures 1-2, 5. A rotating plate 23 is installed at the top end of the base 1. A fixing groove 24 is formed at the top end of the base 1. A convex plate 25 is installed on the surface of the workbench 3. A convex block 26 is installed at the top end of the convex plate 25. A sliding rod 28 is arranged inside the convex block 26. A lifting block 29 is installed at the top end of the sliding rod 28. A stopper 30 is installed at the bottom end of the sliding rod 28. A clamping block 31 is installed at the bottom end of the stopper 30. A spring 32 is installed at the top end of the stopper 30. This improves the adjustment flexibility and stability of the jig. By installing the rotating plate 23 on the base 1 and combining with the design of the fixing groove 24, the operator can easily rotate and fix the workbench 3 to adapt to the processing requirements at different angles. The structures of the convex plate 25 and the convex block 26 ensure the stable movement of the sliding rod 28, and the design of the lifting block 29 facilitates the operator to manually adjust the position of the sliding rod 28. The stopper 30 and the clamping block 31 at the bottom end of the sliding rod 28 are used in cooperation to provide a reliable locking mechanism to prevent the sliding rod 28 from accidentally moving during use. The sliding rod 28 slides inside the convex block 26 through a sliding groove 27. The stopper 30 is slidably connected to the convex block 26. The clamping block 31 slides inside the base 1 through the fixing groove 24. One end of the spring 32 away from the stopper 30 is fixed to the inner wall of the convex block 26. The spring 32 is slidably connected to the sliding rod 28, ensuring the accuracy and smoothness of the position adjustment and avoiding operation inconvenience caused by friction or jamming. The sliding connection between the stopper 30 and the convex block 26 further enhances the stability of the system and prevents accidental displacement.

[0027] Working principle: When in use, first place the base 1 in the required position and firmly fix the base 1 through the installation groove 2. Then place the workpiece on the top of the workbench 3. At this time, hold the rotary handle A10 and rotate it, so that the threaded rod A9 rotates inside the fixed block A7 through the thread groove A8. And at this time, the threaded rod A9 rotates on the side of the clamping plate 12 through the rotating shaft A11, and makes the clamping plate 12 rotate towards the middle on the top of the workbench 3. When the clamping plate 12 contacts the workpiece, it can firmly fix it. And during the sliding process of the clamping plate 12, it will drive the slide bar A13 to rotate, so that the slide bar A13 slides inside the support plate 5 through the slide groove A6. After the workpiece is firmly fixed, then pinch the rotary handle B19 and rotate it, so that the threaded rod B18 rotates downward inside the fixed block B16 through the thread groove B17. At this time, the threaded rod B18 rotates on the top of the pressing plate 21 through the rotating shaft B20, and at this time, the pressing plate 21 drives the slide bar B22 to slide downward, and makes the slide bar B22 slide downward inside the top plate 14 through the slide groove B15. When the bottom end of the pressing plate 21 contacts the top end of the workpiece, it can prevent the situation that the position of the workpiece shifts due to vibration during use. And during use, pinch the lifting block 29 and lift it upward, so that the sliding rod 28 slides upward inside the convex block 26 through the sliding groove 27. At this time, the sliding rod 28 drives the clamping block 31 to slide upward through the stop block 30. When the clamping block 31 completely slides into the inside of the convex block 26 and slides out of the inside of the base 1 through the fixing groove 24, it can be done. At this time, pinch the convex plate 25 and rotate it, so that the workbench 3 rotates on the top of the base 1 through the rotating plate 23, and drives the support plate 5 to rotate through the side plate 4. When the workpiece rotation is completed, release the lifting block 29. At this time, the elastic force of the spring 32 itself will drive the clamping block 31 to slide downward through the stop block 30. When the clamping block 31 slides into the inside of the base 1 through the fixing groove 24, the workbench 3 can be firmly fixed to achieve the effect of rotating and adjusting the workpiece.

[0028] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
