Conflicts are prone to occur between multiple repair tools, and there is a lack of suitable reinforced connection structures. When the device is in use, the repair tool shell needs to be welded and positioned at the installation angle when it is installed in conjunction with the pipeline. There is a lack of suitable quick welding positioning mechanisms. In addition, when the device is in use, after the corresponding shells of the same group are installed, there is a lack of suitable reinforced locking mechanisms, and the installation stability needs to be improved.
