In the aforementioned patent cases, toolboxes with different structures and actuation methods are quite diverse. For example, TW475509 and TWM371068 use a slide cover or flip cover to open and release the restriction on the container, so that they are arranged on the container and The elastic part against the base can turn the container from horizontal to vertical; and the container and flip cover of patents such as TW582328, TWM241196, TWM241197, TWM389004, and TW20137093 have a linkage relationship with each other. The component is connected by a rack or a connecting rod, and can be erected by the action of flipping the cover, or the elastic part is suppressed by the flipping action to achieve the effect of bouncing up the container; in addition, there are also like TWM392723 The user is allowed to manually rotate the gears to drive each accommodating part to turn from horizontal to vertical.

Although the existing related patents are quite diverse, the above-mentioned patents still have several common shortcomings that cannot be overcome:

1. Small size and difficult to handle: the storage parts are arranged parallel to each other, and the storage parts are all turned from horizontal to vertical. The pivot axis of the storage parts is parallel to its own long axis. Therefore, the distance between the storage parts If the space is too close, the range after unfolding is not wide enough, and the user is likely to be disturbed when taking the screwdriver bit from the container.

2. The opening and closing operation is inconvenient: it is often necessary to use a large sliding cover or flip cover to make the container stand up, and in the tool box that uses gears, racks or connecting rods, a certain degree is required when opening. It can only be opened with a certain force, while the tool box that uses manual rotation of the gear has the lack of time-consuming opening and closing operations.
