At the time of mounting, it is only necessary to place the inner casing 3 in the inner space 21 of the casing 2, and to join the upper cover 1, the lower cover 4, and the casing 2. The long post 12 is inserted into the long hole 42 of the lower cover 4, and the upper positioning post 11 and the lower positioning post 41 are respectively inserted through the positioning holes 311 of the inner casing 3, and the upper cylinder 13 and the lower cylinder 43 are also respectively respectively connected to the inner casing. The upper circular hole 24 and the lower circular hole (not shown) are inserted. Thus, the inner casing 3 and the casing 2 can be stably rotated relative to each other. The buckle 6 can be combined with the frame 2 through the spring 5 and the spring hole 23, the spring 5 passes through the buckle 6 and the spring hole 23, and the buckle 6 can rotate to the inside of the frame 2, and the frame 2 and the buckle 6 The end of the opposite end is provided with a bayonet 28, and the bayonet 28 faces the inner side of the frame 2, and can clamp the end of the buckle 6 to prevent the buckle 6 from rotating to the outside of the frame 2, thereby ensuring the safety during the buckle, thereby enabling the electronic storage. The device has the function of a carabiner.

Please refer to Figures 6A and 6B, which are schematic views of the rotating portion. When the inner casing 3 and the frame 2 are not rotated relative to each other, the two side edges of the upper positioning post 11 are parallel to the two side edges 312 of the card slot 31 and are placed in close contact with each other. When an external force is applied, the inner casing 3 and the frame 2 rotate relative to each other. Since the upper positioning post 11 cannot be deformed and cannot rotate, the upper positioning post 11 will press the two side edges 312 of the inner casing 3 to Deformation occurred. When one of the two diagonal apex lines 111 of the upper positioning post 11 is perpendicular to the two side edges 312 of the card slot 31, that is, when the inner casing 3 and the frame 2 are rotated at a relative angle of more than 45 (or 135) When the upper positioning post 11 and the card slot 31 cooperate with each other, the two are pressed against each other, and the inner casing 3 and the frame 2 are relatively rotated by 90° (or 180) by the rebounding force of the side edge 312 of the card slot 31. °). The side of the upper positioning post 11 which is parallel to and in contact with the side 312 of the slot 31 is perpendicular to the side 312 of the slot 31, that is, the inner housing 3 and the frame 2 complete the relative rotation. Similarly, when the angle of relative rotation between the inner casing 3 and the frame 2 is less than 45° (or less than 135°), the upper positioning post 11 and the card slot 31 cooperate with each other, and the two are pressed against each other, and the side of the card slot 31 is utilized. The rebounding force of the edge 312 deforms, and the inner casing 3 and the frame 2 rotate relative to each other by 0 (or 90). That is to say, when an external force is applied to make the inner casing 3 and the frame 2 rotate at an angle of more than 45 (or greater than 135), such as 60, the inner casing 3 is automatically rotated relative to each other and fixed to 90. When the angle of relative rotation of the inner casing 3 and the frame 2 is less than 45° (or less than 135°), such as 30°, the inner casing 3 can automatically return to the original position, and the inner casing 3 and the frame are retained. Body 2 does not rotate relative to each other.

In the electronic storage device, the upper positioning post 11 may have a rectangular cross section, and the positioning angle is 180° or 360°.

When the cross section of the positioning post 11 is a regular polygon, the angle of the relative rotation of the inner casing 3 and the frame 2 is greater than "180° / the number of sides" each time, that is, the cross section of the upper positioning post 11 under the action of an external force. When one of the diagonal vertices 111 is perpendicular to the side 312, the inner casing 3 automatically continues the relative rotation in the direction of the external force due to the rebound force and the external force of the side 312. , positioned in the next state, the relative rotation angle is "360 ° / number of sides".

7A, 7B, and 7C, which are schematic diagrams showing the rotation of the electronic storage device, which are used in a state in which the relative rotation angles of the inner casing 3 and the frame 2 are 90° and 180°, respectively.

The above technical solution is not intended to limit the shape of the positioning post 11, and the shape of the positioning post 11 can be changed as needed. According to the idea of the present invention, the angle of the rotational positioning can be set to other angles according to the use requirement. For example, if the shape of the positioning post 11 is changed to other shapes such as a regular hexagon, the relative rotation angle can be 60° and 120°. Positioning with an angle of 180°.
