Schematic diagram of storage status.

In FIG. 3A and FIG. 3B , the movable part 130 is located at a free position in the storage state. At this moment, the sliding member 141 of the sliding mechanism 110 is at a first position, and the clamping portion 160 is at a buckling position; in FIG. 4A and FIG. 4B , the movable portion 130 is at a transient position. At this time, the sliding member 141 is located at a third position, and the clamping portion 160 moves along the second direction Y at the engaged position and rotates to an unfolded position; in FIG. 5A and FIG. 5B , the movable portion 130 is located at a stop position . At this time, the sliding member 141 is located at a second position, and the clamping portion 160 is located at the maximum clamping position; in FIGS. 6A to 7B , the movable portion 130 returns to the free position. At this time, the sliding member 141 returns to the first position, and the clamping portion 160 can return to the fastened position at the unfolded position.

Comparing FIG. 3A , FIG. 3B and FIG. 5A , when an effective external force F in the first direction X pushes the movable part 130 toward the base 120 , the movable part 130 can move from the free position toward the base 120 to the stopping position. At this time, the movable part 130 pushes the connecting rod 151 , and then the sliding member 141 moves away from the base 120 along the second direction Y by the pushing of the connecting rod 151 . That is, the sliding member 141 moves from the first position to the second position, and the first elastic member 162 also exerts a restoring force on the sliding member 141 due to the displacement of the sliding member 141 . Wherein, the application direction of the restoring force is opposite to the displacement direction of the sliding member 141 .

On the other hand, comparing FIGS. 5A to 6B, once the external force F is removed, the sliding member 141 can return from the second position to the first position by the restoring force of the first elastic member 162, so that the sliding member 141 pushes the connecting rod. 151 , and then the movable part 130 is pushed by the slider 141 and the connecting rod 151 to return from the stop position to the free position.

Referring to FIG. 3A to FIG. 5B at the same time, specifically, when the movable part 130 moves toward the base 120 for a predetermined distance to the transient position, the connecting rod 151 also pushes the sliding member 141 to move to the third position. Because the clamping part 160 will move in the second direction Y by a distance away from the base 120 due to the linkage of the sliding part 141, so that the convex part 181 and the concave part 161 of the fastening part 180 and the clamping part 160 are separated from each other. ; Thereafter, by the torsion of the second elastic member 190, the clamping part 160 will rotate from the fastening position to the unfolded position; then, when the movable part 130 continues to move from the transient position to the stop position, the connecting rod can 151 further pushes the slider 141 to move from the third position to the second position. At this time, the clamping portion 160 linearly displaces along the second direction Y to move away from the base 120 to a maximum clamping position. Wherein, the predetermined stroke of the movable part 130 , that is, the distance from the free position to the transient position, may be 5 cm (mm) to 15 cm, but it is not intended to limit the present invention.

When the movable part 130 moves toward the base 120 to a transient position, and the clamping part 160 moves outward by a predetermined stroke through the sliding structure 110, the clamping part 160 The concave portion 161 is separated from the corresponding convex portion 181 . At this moment, the clamping part 160 can be rotated to the expanded position by the second elastic member 190 .

Furthermore, referring to FIG. 5A to FIG. 6B at the same time, once the external force F on the movable part 130 is removed, the sliding member 141 will move toward the base 120 along the second direction Y by the pulling force of the first elastic member 162. The connecting rod 151 also moves along with the sliding member 141 to push the movable part 130 away from the base 120 along the first direction X. On the other hand, if an object (not shown) is placed between the two clamping parts 160 before the external force F is removed, then the clamp 100 can pass through the clamping parts 160 after the external force F is removed. Holds objects securely.

In addition, referring to Fig. 5A to Fig. 7B at the same time, if it is desired to separate the object from the clamp 100 and store the clamp 100, it is only necessary to apply an external force F to the movable part 130 again, so that the clamping part 160 is linearly displaced in the second direction Y again. away from the base 120, thereby allowing the clamp 100 to release the object. At this time, after taking out the object, the external force F on the movable part 130 can be removed, so that the clamping part 160 can be moved by the linkage of the first elastic part 162, the sliding part 141, the connecting rod 151 and the sliding block 131, etc. and return to the expanded position. Thereafter, it is further rotated toward the base 120 to return to the buckled position, so that the clip 100 returns to the stored state. Wherein, the clipping part 160 may rotate on a plane perpendicular to the first direction X and parallel to the second direction Y during the process of returning from the unfolded position to the buckled position.
