[0002] Chemical enterprises often use oil barrels of various specifications to store and transport liquid chemical raw materials, additives, etc. The covers of these oil barrels have diverse specifications, and chemical products have high requirements for tightness. The barrel covers are often difficult to open tightly. Therefore, a special tool that can adapt to various barrel cover specifications is needed.

[0003] Currently, the traditional method of opening an oil barrel cover is mostly by using a screwdriver and a hammer. Although it is simple, it requires frequent knocking. The operation is not only time-consuming but also poses a safety risk. Moreover, different specifications of tools are required for oil barrel covers of different sizes and structures, resulting in poor applicability.

[0004] Therefore, there is an urgent need to set up a structure that can flexibly adjust the oil cover chuck according to the oil covers of different sizes, solving the problem of inability to adapt to oil barrel covers of different specifications. Summary of the Utility Model
