[0002] The civil air defense door frame is the main component of the civil air defense door, and is mostly welded by a plurality of door frame side rod bodies. In the production process of the civil air defense door, manual hoisting and manual clamping are required. In the clamping process, the door frame side rod bodies are heavy, which leads to inconvenience in movement and difficulty in assembly.

[0003] To solve the above problems, the patent with publication number CN117300456A discloses a quick butt welding device for civil air defense door frame and its processing technology. The device includes a support assembly, a sliding assembly, a tool frame, a rotating assembly, a driving assembly, and four clamping assemblies. The support assembly includes a support plate and two support rods. The two support rods can slide towards each other or away from each other. The sliding assembly is connected to the support plate, and the sliding assembly is connected to the support rods to drive the movement of the support rods. The tool frame is located between the two support rods. The rotating assembly includes two first rotating members and two extension members. One end of the extension member is connected to the first rotating member, and the other end is connected to the tool frame. The first rotating member is used to drive the tool frame to flip. The driving assembly includes a second lifting member and a second rotating member. The second lifting member is connected to the tool frame. The four clamping assemblies are distributed circumferentially along the second rotating member. The four clamping assemblies can be assembled into a civil air defense door frame. The application has the effect of improving the difficulty of welding the door frame by personnel.

[0004] For the related technology in the above, the inventors found that in the rotating process of the above-mentioned device, the civil air defense door frame may loosen during the rotating process, causing deformation of the welding area and easily causing safety accidents. There is a lack of effective clamping at the weld, which can easily cause large displacement during the welding process. The rod of the cylinder in the device bears the weight of the civil air defense door frame in the radial direction, which can easily cause the extension end of the cylinder to deform after long-term use, reducing the welding precision. The above problems reduce the precision of the door frame and increase the safety risk. UTILITY MODEL CONTENTS
