Technical Field

[0001] The utility model relates to the field of opening tools, and particularly relates to an opener. Background Art

[0002] In industrial production, liquid raw materials are mainly stored in plastic barrels. The traditional structure of a plastic barrel usually includes a barrel lid, an oil outlet lid, and a barrel body. Among them, the barrel lid is tightly closed on the opening of the barrel body to ensure the sealing and storage stability of the liquid raw materials. The oil outlet lid is screwed at the oil outlet hole of the barrel lid to facilitate the extraction of the liquid and control the outflow rate. The design of the oil outlet lid often includes a sunk groove and two internal teeth provided on the inner peripheral wall of the sunk groove.

[0003] In practical applications, to ensure the sealing performance, both the barrel lid and the oil outlet lid are installed very tightly, which makes it quite difficult to open them. Operators need to use matching tools to open them. For example, the barrel lid generally needs to be pried open with tools such as pliers or crowbars, and for the oil outlet lid, a wrench adapted to the diameter of the sunk groove needs to be inserted between the two internal teeth of the sunk groove and abutted against the internal teeth, and then the wrench is rotated to drive the oil outlet lid to screw out of the oil outlet hole through the internal teeth.

[0004] The above-mentioned opening methods for the barrel lid and the oil outlet lid of the plastic barrel have obvious deficiencies. Different tools are required to open the barrel lid and the oil outlet lid, and wrenches of different specifications are needed for oil outlet lids of different diameters, which leads to the diversity of tool use and the increase in storage space, and further makes tool management more difficult.
