Common shared charging cabinets include power bank shared charging cabinets. Shared charging cabinets generally include cabinets, charging cabinet compartments, code scanning units, communication units, charging items, charging lines, etc. Common charging items include power banks.

[0003] The interpreter is an automatic interpreting device that can be used in any life scenario where content needs to be conveyed. It is more common in the tourism industry. Visitors to museums and scenic spots can automatically receive the introduction of the site within the effective signal reception range without any operation by carrying the interpreter, and enjoy humanized service.

[0004] The interpreter is inconvenient to carry by hand, in pocket or in a backpack. The interpreter also requires separate earplugs during use, which is inconvenient and unhygienic. Existing interpreter rentals generally require manual operation, which is cumbersome. Due to the lack of corresponding shared charging cabinets, unmanned rental is not possible.

[0005] At present, shared charging cabinets have problems such as the inability to smoothly switch between the locked and unlocked states of charging items when inserting them into and removing them from the charging cabinet compartment, the positioning and locking mechanism on the charging cabinet compartment used to position and lock charging items is complex and energy-intensive, and the charging items are ejected with great force, causing them to fall.
