Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly instruments, and particularly relates to an adjustable wrench. Background Art

[0002] A wrench is a commonly used installation and disassembly tool and can be applied to disassembly and assembly operations in multiple industries. In the field of water treatment technology, a cation and anion exchanger is usually used for water purification. Its principle is mainly based on the ion exchange method. Through the synergistic effect of cation exchange resin and anion exchange resin, cations and anions in water are removed, so as to achieve the purpose of purifying water. When the cation and anion exchanger is in use, it needs to be regularly maintained. When disassembling the resin barrel of the cation and anion exchanger, the plug on the resin barrel needs to be removed. However, there are only two holes on the plug, and there is no corresponding tool to remove the plug, resulting in difficult operation and long disassembly operation time.

[0003] In summary, there is an urgent need to provide an adjustable wrench to solve the problems existing in the prior art. Summary of the Utility Model
