[0023] Embodiment 1

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a clamping device for preventing clamping damage, which includes a base 1. A first sliding groove 2 is formed on the surface of the base 1. A first sliding block 3 is slidably connected inside the first sliding groove 2. A second sliding groove 4 is formed inside the first sliding block 3. A second sliding block 6 is slidably connected inside the second sliding groove 4. A limiting block 7 is fixedly installed on the side of the second sliding block 6 away from the second sliding groove 4. A moving plate 8 is fixedly installed on the side of the limiting block 7. A first rotating rod 9 is rotatably connected to the side of the moving plate 8 away from the limiting block 7. A first rubber block 10 is fixedly installed on the surface of the first sliding block 3. A second rubber block 11 is fixedly installed on the side of the base 1 close to the first rubber block 10. A rotating block 12 is rotatably connected inside the first sliding block 3. A first threaded rod 13 is fixedly installed on the side of the rotating block 12 away from the first sliding block 3. A second rotating rod 14 is fixedly installed on the side of the first threaded rod 13 away from the rotating block 12. The first threaded rod 13 is threadedly connected to the base 1. By the threaded connection between the first threaded rod 13 and the base 1, the first threaded rod 13 can move when rotating, and can push the rotating block 12 and the first sliding block 3 to move together. The operation is convenient and fast, reducing the difficulty for workers to operate the fixture and improving the work efficiency. The number of the second sliding groove 4, the spring 5, the second sliding block 6, the limiting block 7, the moving plate 8 and the first rotating rod 9 is two groups, and the two groups of the second sliding groove 4, the spring 5, the second sliding block 6, the limiting block 7, the moving plate 8 and the first rotating rod 9 are symmetrically distributed on both sides of the first threaded rod 13. The two groups of the second sliding groove 4, the spring 5, the second sliding block 6, the limiting block 7, the moving plate 8 and the first rotating rod 9 jointly limit the threaded rod. When cleaning or maintenance is needed, the limiting block 7 can be directly slid, and then the rotating block 12 can be removed from the first sliding block 3 through the first threaded rod 13, and then the first sliding block 3 can be taken out and maintained. The operation is convenient and fast, greatly reducing the cost of maintenance work. The radius of the rotating block 12 is larger than the radius of the first threaded rod 13. The arc surface radius of the limiting block 7 is the same as the radius of the first threaded rod 13. The rotating block 12 can be restricted inside the first sliding block 3 by the two groups of limiting blocks 7, so as to limit the thread and prevent the first threaded rod 13 from loosening when the clamping device needs to loosen the clamped object, resulting in the first sliding block 3 being unable to move with the first threaded rod 13 and affecting the use of the clamping device. The shapes of the first sliding groove 2, the first sliding block 3, the second sliding groove 4 and the second sliding block 6 are all T-shaped. The first sliding groove 2, the first sliding block 3, the second sliding groove 4 and the second sliding block 6 cooperate with each other respectively, avoiding the first sliding block 3 and the second sliding block 6 falling off during use and affecting the work efficiency, and improving the stability of the clamping device.

[0025] Embodiment 2

[0026] Please refer to Figures 4-5, a clamping block 15 is provided on the bottom surface of the base 1. A second threaded rod 16 is threadedly connected to the side of the clamping block 15 away from the base 1. A third rotating rod 17 is fixedly installed on the bottom surface of the second threaded rod 16. An elastic buckle 18 is fixedly installed on the top of the clamping block 15. A bayonet 19 is formed on the side of the base 1 close to the clamping block 15. The clamping tool can be clamped and fixed on any workbench through the clamping block 15 and the second threaded rod 16 for work. While facilitating the fixation of the clamping device, it also facilitates the staff to move the clamping device to other locations for work, greatly improving the practicality of the clamping device. The shapes on both sides of the elastic buckle 18 are triangular. The elastic buckle 18 corresponds to the position of the bayonet 19. The triangular elastic buckle 18 can be removed from the bayonet 19 by simply applying downward force, thereby removing the clamping block 15 from the base 1. The staff can decide whether to leave the clamping block 15 and the second threaded rod 16 according to whether the clamping device is fixed in one place, enabling the staff to choose the fixing method of the fixture according to the actual situation, greatly improving the practicality of the fixture.

[0027] Working principle: When fixing the clamping device, first determine whether the clamping device needs to be permanently fixed at the same location. If the clamping device needs to be permanently fixed at the same location, remove the clamping block 15 and use bolts or other methods to fix the clamping device. If the clamping device does not need to be permanently fixed at the same location, place the clamping block 15 on the workbench where clamping work needs to be carried out, and then turn the second threaded rod 16 to tighten the second threaded rod 16 against the workbench. When changing the work location, turn the second threaded rod 16 to loosen the second threaded rod 16 from the workbench, and then the clamping device can be removed and moved to the next work location. When cleaning or maintaining the clamping device, first pull the first rotating rod 9, and then the first rotating rod 9 drives the moving plate 8, the limiting block 7, and the second slider 6 to move outward along the second chute 4. At the same time, the spring 5 is compressed. When the first rotating rod 9 moves to the outside of the first slider 3, turn the first rotating rod 9 to rotate it by ninety degrees, and then release the first rotating rod 9. Then the spring 5 rebounds to make the first rotating rod 9 catch on the side of the first slider 3. Then turn the second rotating rod 14. While the second rotating rod 14 drives the first threaded rod 13 to rotate, it also drives the first threaded rod 13 and the rotating block 12 to move outward. When the rotating block 12 moves out of the first slider 3, the first slider 3 can be removed from the first chute 2, and then the clamping device can be cleaned or maintained, greatly saving the time and labor of the staff for cleaning or maintaining the clamping device.

[0028] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as they do not depart from the technical solution content of the present utility model, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
