Abstract

A fastener structure includes a body portion, a control portion and a fastening portion. The control portion is movably fitted to the body portion. The control portion has a head portion and a limiting portion. The fastening portion is movably disposed at the body portion. The limiting portion is adapted to limit the fastening portion. Therefore, the body portion is disposed at the second object, and the control portion causes the fastening portion to be coupled to or separated from the first object, so as to couple together and separate at least two objects repeatedly and rapidly.

First claim

What is claimed is:

1. A turning interlocking coupling structure, comprising:
a head, comprising a limiting portion;
a fastening portion, coupled with the head; and
a body, movably coupled with the head and rendering the fastening portion to be extended to the body, the body comprising a first stopping portion and a second stopping portion, the body being configured to be assembled to a first object, the head being, when driven, limited at the first stopping portion or the second stopping portion by the limiting portion, so as to enable the fastening portion to be unfastened from or be fasteningly connected to a second object;
wherein a guiding portion is provided between the first stopping portion and the second stopping portion, and the head has a yielding through hole for allowing the guiding portion to pass through.

2. The turning interlocking coupling structure according to claim 1 , wherein one end of the fastening portion is coupled to the head by a bolt connector.

3. The turning interlocking coupling structure according to claim 2 , further comprising:
an elastic element, one end of the elastic element being abutted against the head and one other end of the elastic element being abutted against the body.

4. The turning interlocking coupling structure according to claim 1 , wherein a fastener is provided on one end of the fastening portion and is configured to be fasteningly connected to the second object.

5. The turning interlocking coupling structure according to claim 1 , wherein the body comprises an assembly portion, the assembly portion is configured to be assembled to the first object and comprises a feed trough, the turning interlocking coupling structure is configured to receive pressure of an external force such that a material of the first object is pressed into or flows into the feed trough so as to enable the assembly portion to be assembled with the first object.

6. The turning interlocking coupling structure according to claim 1 , wherein the body comprises a shoulder configured to be leaned against the first object.

7. The turning interlocking coupling structure according to claim 1 , wherein the head comprises two limiting portions configured to correspond in position to the first stopping portion and the second stopping portion.

8. The turning interlocking coupling structure according to claim 1 , wherein the limiting portion is configured to limit the head to move longitudinally according to a structure of the first stopping portion or the second stopping portion.

9. The turning interlocking coupling structure according to claim 1 , wherein the head is configured to move downward and to move according to a structure of the first stopping portion or the second stopping portion by the limiting portion, and to enable the guiding portion to move rotationally in the yielding through hole when passing through the yielding through hole, so as to drive the fastening portion to rotate.

10. The turning interlocking coupling structure according to claim 1 , wherein an allowance space is provided below the guiding portion and is configured to allow the guiding portion to pass through the yielding through hole of the head, so as to give way to a non-yielding structure of the head and to enable the head to rotate by the allowance space.

11. The turning interlocking coupling structure according to claim 5 , wherein shoulder of the body is pressed by an external force so as to enable the assembly portion to be assembled with the first object.

12. The turning interlocking coupling structure according to claim 1 , further comprising:
an elastic element, one end of the elastic element being abutted against the head and one other end of the elastic element being abutted against the body, the elastic element being a torsion spring, and being configured to limit position by the limiting portion and the first stopping portion or to limit rotation by the second stopping portion and to automatically rotate when the yielding through hole of the head enters the guiding portion of the body, so as to drive the fastening portion to rotate automatically.

13. The turning interlocking coupling structure according to claim 3 , wherein the elastic element is a torsion spring configured to limit position by the limiting portion and the first stopping portion or to limit rotation by the second stopping portion, and to automatically rotate when the yielding through hole of the head enters the guiding portion of the body, so as to drive the fastening portion to rotate automatically.

14. The turning interlocking coupling structure according to claim 1 , wherein the yielding through hole is configured to release interference from or limit an amount of movement of the guiding portion.

15. The turning interlocking coupling structure according to claim 1 , wherein a structure of the guiding portion and the yielding through hole is configured to limit an amount of rotation or movement of the head, or to limit a stop position of rotation or movement of the head.
