The rotation axis S2 of the second pivot portion 22 is parallel to the rotation axis S1 of the first pivot portion 21.

The limiting surface 23 is formed on a top surface of the second body portion 22 of the second pivot portion 22 that is convex toward the rear side. The limiting surface 23 is a sloped surface and is adjacent to the shaft pin 212 and two away from the shaft pin 212. Each of the sides is provided with a proximal side 231 and a distal side 232. The distance between the distal side 232 and the rotation axis S2 of the second pivot portion 22 is greater than the distance between the proximal side 231 and the rotation axis S2 of the second pivot portion 22.

The cover 30 is a cover that can be covered on the pivoting unit 20, and a pair of pivot holes 32 are formed on the left and right sides of the rear end. The front side of the cover 30 protrudes forward from the base. A fastening edge 31 of the rear hook is formed on the front edge of the front end of the buckle cover 30. The fastening edge 31 can be hooked to the hook portion A21 of the second housing A2. The pair of pivot holes 32 can be rotated. The sleeve is disposed on the pair of protrusions 222, whereby the buckle cover 30 can pivot relative to the pivot unit 20. The inner side surface of the rear end of the buckle cover 30 abuts against the limiting surface 23, and the limiting surface 23 is restricted from pivoting backward. The detailed operation mode will be described later.

The manner in which the buckle cover 30 is pivotally connected to the second pivot portion 22 and the manner in which the first pivot portion 21 is pivotally connected to the base portion 10 may be other forms, such as not providing a shaft bolt but pivoting together. It is also possible to circlip the pin to the semi-open card slot, and the creation is not limited.

The elastic member 40 is disposed between the pivoting unit 20 and the buckle cover 30 and abuts against the pivoting unit 20 and the buckle cover 30 to provide an elastic force to the buckle cover 30 to the pivoting unit 20 . After the cover is closed, it can be bounced back from the state in which the pivotal unit 20 is closed. Preferably, the elastic member 40 is a torsion spring and is disposed at one end of the cylinder 221 of the pivoting unit 20, and is provided with a fixed end 41 and an abutting end 42. The receiving end 42 of the pivoting unit 20 abuts against the inner side of the buckle cover 30. In the present invention, the elastic member 40 may also be a spring piece or other material having resilience. The present invention does not specifically limit the form of the elastic member 40.

In the present creation, although the number of the buckles B is two, it may be one, and the creation does not impose a specific limit on the number of the buckles B.

As shown in FIG. 5, the buckle B of the preferred embodiment of the present invention is unfastened. The counterclockwise force is generated by the return elastic force of the elastic member 40, so that the buckle cover 30 is pivoted in the counterclockwise direction to bounce off from the state in which the pivotal unit 20 is closed, but the inner side of the rear end of the buckle cover 30 is Abutting the limit surface 23 of the creation, and the distance between the distal side 232 of the limiting surface 23 and the rotation axis S2 of the second pivot portion 22 is greater than the distance between the proximal side 231 and the rotation axis S2 of the second pivot portion 22 (ie, Pivot radius), so the buckle cover 30 will be limited by the distal side 232 of the limiting surface 23 and will not continue to pivot in the counterclockwise direction to limit the degree of pivoting of the buckle cover 30 backwards, so that the buckle cover 30 will not The whole is turned outwards to expose the pivot unit 20 and the elastic member 40.

The fastener B of the preferred embodiment of the present invention is engaged with the continuous action of the body A of the tool case, as shown in FIGS. 6 and 7. The lower left side of FIG. 6 is the initial state for the buckle B to be engaged, that is, the state of FIG. 5, and then the user manually pulls the rear side of the buckle cover 30 to make the pivoting unit 20 the first pivot. The shaft pin 212 of the portion 21 is pivoted clockwise, that is, the state above the side of Fig. 6. Finally, after the fastening edge 31 of the front end of the buckle cover 30 is fastened to the hook portion A21 of the second box A2, the rear side of the buckle cover 30 is pressed downward, and the elastic member 40 is compressed, as shown in FIG. The state of the lower right side, and the buckle cover 30 covers the pivoting unit 20 to be in a locked state, that is, the action of the buckle B to fasten the toolbox body A is completed.

As shown in FIG. 8, the continuous action of releasing the buckle B is performed. As shown in the left side of FIG. 8, the user manually pulls the rear side of the buckle cover 30 to disengage the fastening edge 31 from the hook portion A21 of the second casing A2. At this time, the compressed elastic member 40 generates a resilient force and instantaneously. The counterclockwise force is generated such that the buckle cover 30 is pivoted by the rotation axis S2 of the second pivot portion 22 to be bounced by the state of the cover pivoting unit 20 while the pivoting unit 20 is pivoted by the first pivot portion 21 The rotation axis S1 is an axis and rotates counterclockwise.
