Description

TECHNICAL FIELD

[0001] The present application relates to a chuck storage device, in particular, to a chuck storage device which can accurately store, flexibly configure and improve the practicability. BACKGROUND

[0002] As shown in Figure 14 and Figure 15 , the existing chuck storage device 50 is mainly used to provide a function of storing a chuck 40. The existing chuck storage device 50 is provided with a storage box 51 and a protective cover 52. The storage box 51 is provided with a plurality of storage slots 511 arranged in a chessboard pattern. The plurality of storage slots 511 are used for placing the chucks 40 and have the same size, so as to store the chucks 40 with the same appearance size. Each of the chucks 40 is marked with a corresponding size symbol (corresponding to the size of the tool) on the outer surface. The protective cover 52 can be arranged on the storage box 51 to prevent dust or impurities from accumulating on the chucks 40 in the storage box 51.

[0003] Although the existing chuck storage device 50 can provide the effect of storing the chucks 40, the size symbols on the outer surface of each of the chucks 40 cannot be clearly displayed due to wear after long-term use. In addition, each of the storage slots 511 has the same size. Therefore, the user cannot know the size symbols of the chucks 40 with the same appearance size placed in each of the storage slots 511. The user can only know whether the taken chuck 40 corresponds to the size of the tool by combining each of the chucks 40 with the tool to be used, which increases the inconvenience and time-consuming in use. Further, the storage box 51 of the existing chuck storage device 50 has a certain volume and shape. Therefore, only a certain number of chucks 40 can be stored, and the storage box 51 cannot be adjusted according to the needs of the user. For example, when the existing chuck storage device 50 is placed in a small space, the fixed type storage box 51 cannot meet the above needs. Further, when more chucks 40 than the number of the storage slots 511 are to be stored, the existing chuck storage device 50 cannot meet the needs of the user. The user can only purchase another existing chuck storage device 50 for use, which relatively limits the practicability of the existing chuck storage device 50. In summary, the existing chuck storage device 50 needs to be improved. SUMMARY
