In order to facilitate carrying and protect the fusion splicer, the fusion splicer is placed in a tool box when it is carried out. In addition, when performing outdoor fiber splicing work, it is also necessary to carry tools such as a level and a stripping clip, so the tool box needs to have a reliable structure and be convenient and practical. The tool box generally consists of a box with a cavity and a cover for covering the box. In order to ensure that the tool box will not be opened during carrying and to prevent the internal items from falling and being damaged, the box and the cover are generally connected and fixed by a lock or a lock with a key.
[0003] The tool boxes on the market generally use a buckle to press the lock for locking. When locking, the buckle needs to be buckled into the recessed position, and then the unlocking part at one end of the buckle is pressed to tightly buckle the buckle into the recessed position without disengaging, thereby locking the box; when unlocking, the unlocking part needs to be lifted to loosen the buckle and disengage from the recess, thereby unlocking the box; the lock of the above structure is inconvenient to use, and a large force is required to buckle the buckle of the lock into place when locking, and the buckle is prone to deformation after being used for a period of time, which makes the lock easy to be misaligned, affecting the sealing of the tool box and having poor reliability.
[0004] However, a tool box that is connected and fixed with a lock with a key needs to be carried with the key, and the key needs to be used to unlock the box each time the lid is opened. The operation is relatively cumbersome and inconvenient to use, which affects the user experience.
[0005] The technical problem to be solved by the present application is: how to solve the defects of the locking structure of the existing tool box, such as being inconvenient to use and having low reliability. Utility Model Content
