[0040] The above-mentioned various structures jointly constitute the general appearance structure of the civil engineering fixing structure.

[0041] According to Figure 1 and Figure 4 As shown in the drawings, in order to further explain the specific working principle of the civil engineering fixing structure, the above-mentioned extrusion protection device 7 comprises a connecting plate 701 fixedly connected to the fixed rod 6, a telescopic rod one 705 for guiding is fixedly connected to the side of the connecting plate 701 away from the fixed rod 6, a fixed plate 703 is fixedly connected to the side of the telescopic rod one 705 away from the connecting plate 701, and a plurality of anti-skid blocks 704 are fixedly connected to the fixed plate 703.

[0043] Then, two fixed blocks 709 are fixedly connected to the front and rear sides of the connecting plate 701 close to the fixed plate 703, the two fixed blocks 709 are arranged in front and rear symmetry, a guide rod 708 is fixedly connected to the close sides of the two fixed blocks 709, a sliding block 707 is slidingly connected to the guide rod 708, the sliding block 707 is slidingly connected to the connecting plate 701, then, a damping spring two 710 is fixedly connected to the sides of the two sliding blocks 707 away from each other, the other end of the damping spring two 710 is fixedly connected to the corresponding fixed block 709, and the damping spring two 710 is sleeved on the guide rod 708.

[0045] The technical effect achieved by the technical solution composed of the above-mentioned technical features is as follows: When the fixing rod 6 drives the compression protection device 7 to fix the template, the anti-slip block 704 on the fixing plate 703 first adheres tightly to the template. Subsequently, the fixing plate 703 gradually applies force, causing the shock-absorbing spring 702 and the telescopic rod 705 connected to it to be compressed simultaneously. During this process, the rotating plates 706 of the two devices begin to rotate, pushing the corresponding sliding blocks 707 to move in the opposite direction, thereby causing the second shock-absorbing spring 710 to be gradually compressed as well. Through this double-spring compression mechanism, the device can effectively avoid excessive pressure on the template, ensuring safety during the fixing process. Finally, after the fixing plate 703 fixes the template, the fixing rod 6 stops moving.

[0046] according to Figures 1 to 4 As shown, during use, first loosen the bolts and remove the two connecting blocks 9. Then, rotate the handle 4 to drive the bidirectional spiral rod 3 to rotate. The two threaded blocks 5 drive the corresponding fixing rods 6 to move towards the same side. The fixing rods 6 drive the compression protection device 7 to move, and then fix the civil engineering formwork. Then, extend and retract the telescopic rod 10 to a suitable length. Next, re-insert the two connecting blocks 9 into the connecting groove 8 and fix the connecting blocks 9 in the connecting groove 8 with bolts. Finally, the connecting handle drives the transmission threaded rod 13 to rotate, and the transmission threaded rod 13 can drive the limiting plate 14 to move back and forth. Thus, the equipment can fix civil engineering formwork of various sizes.
