Tool box

A tool box, comprising:

• a first housing, having a first bottom wall, a first circumferential wall connected to the first bottom wall, and a first accommodating space defined between the first bottom wall and the first circumferential wall, the first accommodating space having a first opening, the first housing further having a first guide portion and a second guide portion extending outwardly toward the first opening;
• a second housing, connected to the first housing, the second housing having a second bottom wall, a second circumferential wall connected to the second bottom wall, and a second accommodating space defined between the second bottom wall and the second circumferential wall, the second accommodating space having a second opening, at least one portion of the second circumferential wall being connected to the first circumferential wall through a hinge member so that the second housing is rotatable relative to the first housing with the hinge member as its axis of rotation to be in a closed position or an open position, wherein when in the open position, the second housing is moved away from the first housing, wherein when in the closed position, the second housing covers the first housing, wherein the second housing includes a first connecting portion and a second connecting portion in the second accommodating space;
• a first receiving seat, accommodated in the second accommodating space and rotatably connected to the first connecting portion, the first receiving seat being provided with a plurality of spaced first receiving grooves, at least one first elastic member being connected to the first receiving seat, wherein when the second housing is moved toward the open position, the first elastic member pushes the first receiving seat to rotate in a first direction and extend out of the second opening therefore making the first receiving grooves face toward the exterior of the second opening, wherein the first receiving seat has a first abutting portion corresponding to the first guide portion, wherein when the second housing is moved toward the closed position, the first abutting portion is guided by the first guide portion to drive the first receiving seat to rotate in a second direction opposite to the first direction and to be received in the second accommodating space;
• a second receiving seat, accommodated in the second accommodating space, and rotatably connected to the second connecting portion, the second receiving seat being provided with a plurality of spaced second receiving grooves, at least one second elastic member being connected to the second receiving seat, wherein when the second housing is moved toward the open position, the second elastic member pushes the second receiving seat to rotate in the second direction and extend out of the second opening therefore making the second receiving grooves face the second opening, wherein the second receiving seat has a second abutting portion corresponding to the second guide portion, wherein when the second housing is moved toward the closed position, the second abutting portion is guided by the second guide portion to drive the second receiving seat to rotate in the first direction and to be received in the second accommodating space;
• wherein when the second housing is moved from the open position to the closed position, the first abutting portion first contacts the first guide portion and is guided by the first guide portion to drive the first receiving seat to rotate in the second direction, and then the second abutting portion contacts the second guide portion and is guided by the second guide portion to drive the second receiving seat to rotate in the first direction, a central axis of the second receiving grooves and a central axis of the first receiving grooves are located on different planes, when a plurality of bits are respectively placed in the first receiving grooves and the second receiving grooves, the bits received in the first receiving grooves and the bits received in the second receiving grooves are partially overlapped.
