[0002] Currently, the airtightness requirements for open-top steel drums used to package special substances are becoming increasingly stringent. The protective gas inside the drum must be completely leak-proof to protect the contents from air contamination outside. This requires that every part of the open-top steel drum must be leak-proof, and the assembly of the drum has a significant impact on its airtightness.

In addition, the steel drum itself has no corresponding positioning measures during the clamping process. During the clamping process, the steel drum is easily placed unsteadily due to external force, resulting in uneven clamping of the opening or tipping of the steel drum and failure of the clamping work.
