[0002] Civil defense doors refer to emergency escape passages built to deal with unexpected events such as war. They are also commonly known as air-raid doors. Civil defense doors are emergency facilities and are one of the important measures to ensure people's lives and safety.

[0028] A sliding sleeve 26 is fixedly connected to any end of the first sliding rod 242, and a second sliding rod 25 is slidably connected inside the sliding sleeve 26.

[0031] When in use, the staff first places the door frame and door panel of the civil air defense door on the upper end surface of the workbench 1, and then turns on the motor 21. The power output shaft of the motor 21 rotates, and the rotation of the power output shaft of the motor 21 drives the rotating rod 22 to rotate. The rotation of the rotating rod 22 drives the first fixed block 23 to rotate. The rotation of the first fixed block 23 drives the spring 241 to squeeze and move. The movement of the spring 241 drives the sliding block 243 to slide on the fixed rod 244. The sliding of the sliding block 243 drives the connecting rod 245 to slide. The sliding of the connecting rod 245 drives the U-shaped block to slide on the first sliding rod 242, so that the welding gun 332 slides in a large range outside the civil air defense door, and the civil air defense door is welded for one circle, and then the angle of the welding gun 332 is adjusted by adjusting the component 3;

[0032] The adjusting assembly 3 specifically comprises a U-shaped block 31, a first limiting plate 32, a serrated fixing plate 321 and a second fixing block 322.
