[0039] Working principle: when the upper clamping beam is needed to clamp the clamping component, the structural component is placed between the two clamping plates 9, the two tightening rings 18 are loosened first, and then the rotating ring 3 is rotated to drive the threaded rod 2 to rotate through the rotating ring 3, and the threaded rod 2 will also drive the two clamping plates 9 to move towards each other to clamp the clamping component, and the ratchet 5 will also cooperate with the card block 8 to allow the threaded rod 2 to rotate in only one direction to prevent the clamping plate 9 from loosening the clamping component. When the clamping component needs to be loosened, just move the top of the card block 8 so that the card block 8 will no longer engage with the ratchet 5 under the condition of squeezing the push spring 1 7. At this time, the threaded rod 2 can be unlocked in one direction to allow the clamping plate 9 to loosen the clamping component. When the clamping plate 9 clamps the component, the push spring 2 13 will push the limit The positioning ring 12 pushes the clamping column 11 to fit tightly against the surface of the clamping component. When the clamping plate 9 clamps the clamping component, the clamping column 11 is allowed to fit tightly against the surface of the clamping component, so that the clamping surface is in contact with the component surface more evenly, making the clamping process more stable and avoiding sliding or displacement, thereby ensuring the clamping effect and working stability. When the support assembly needs to be used to support the lower half of the clamping plate 9, after the clamping of the clamping plate 9 is completed, the tightening ring 18 is turned by hand to allow the tightening ring 18 to cooperate with the connecting column 17 to fix the reinforcement plate 15. The fixed reinforcement plate 15 will support the lower half of the clamping plate 9, providing it with additional support, so that the clamping component is clamped more stably and unnecessary shaking or movement is reduced.
