[0026] It should be noted that: when the iron sheet 11 needs to be clamped, the rotating ring 46 can be rotated to drive the clamping plate 41 to move close to the iron sheet 11. Since the supporting rod 42 is rotatably installed on the connecting rod 43, the clamping plate 41 will move along the axis direction of the supporting rod 42 and gradually move close to the outer wall of the iron sheet 11. When the clamping plate 41 completely clamps the iron sheet 11, the connecting column 45 and the connecting rod 43 are also in a stable state, ensuring that the entire clamping mechanism is firmly fixed on the iron sheet 11.

[0027] Further, the clamping mechanism effectively enhances the stability of the iron sheet 11 and the structure around it. Through the cooperation of the bottom ring 44, the connecting column 45, the connecting rod 43, the supporting rod 42 and the clamping plate 41, the iron sheet 11 can be firmly fixed at a predetermined position to prevent displacement or deformation during the concrete pouring process.

[0028] Further, since the clamping plate 41 is rotatably installed on the connecting rod 43 through the supporting rod 42, the clamping force of the clamping plate 41 can be flexibly adjusted according to actual needs, so that the formwork device can adapt to the manufacturing requirements of manhole covers of different sizes and shapes, improving the versatility and practicality of the formwork.

[0029] Further, the guide plate 47 solves the problem of concrete leakage in the concrete pouring process, forms an effective leakage prevention barrier, and ensures that the concrete can be completely filled inside the iron sheet 11.
