Abstract

A fittable and releasable fastener includes a head which has a fitted and released portion and a fastening portion; and a fitting and releasing piece which has a fitting and releasing portion. Accordingly, when the fitting and releasing portion fits to the fitted and released portion, an external turning force is applied to the fitting and releasing piece or the head to make the fastening portion combine with at least one object. After the fastening portion is combined with the object, the fitting and releasing portion would release the fitted and released portion to limit the force or the force interval applied on the fastening portion for preventing excessively locking if the force is continuously applied.

First claim

What is claimed is:

1. A fittable and releasable fastener, comprising:
a head, having at least one fitted and released portion and a first combining portion; and
a fitting and releasing piece, having at least one fitting and releasing portion and a second combining portion, the head combining moveably with the fitting and releasing piece, and the fitting and releasing portion performing fitting and releasing with the fitted and released portion, the first combining portion or the second combining portion having a receiving space, and the first combining portion or the second combining portion being pressed by an external force for allowing the material of an object or another object to enter or flow into the receiving space so as to combine with the object or the another object.

2. The fittable and releasable fastener according to claim 1 , wherein the fittable and releasable fastener has a shaft portion, and the head combines moveably with the fitting and releasing piece by the shaft portion to make the head or the fitting and releasing piece turn against the shaft portion so that the fitting and releasing portion can perform fitting and releasing with the fitted and released portion.

3. The fittable and releasable fastener according to claim 1 , wherein the head or the fitting and releasing piece has an assembly positioning portion, and the assembly positioning portion can define the position of the fitted and released portion of the head or the fitting and releasing portion of the fitting and releasing piece as a damping position or limit of a direction.

4. The fittable and releasable fastener according to claim 1 , wherein the fitting and releasing portion or the fitted and released portion has a fitting and releasing surface and a stopping surface, a direction of the fitting and releasing surface is fittably and releasably turning, and a direction of the stopping surface is restrained from turning, or a force toward the direction of the stopping surface for fittably and releasably turning is enlarged.

5. A fittable and releasable fastener, comprising:
a head, having at least one fitted and released portion and a first combining portion; and
a fitting and releasing piece, having at least one fitting and releasing portion and a second combining portion, the head combining moveably with the fitting and releasing piece, and the fitting and releasing portion performing fitting and releasing with the fitted and released portion, the first combining portion or the second combining portion being used to be pressed by an external force to form a receiving space for allowing the receiving space to lock the object or the another object so as to combine with the object or the another object.

6. The fittable and releasable fastener according to claim 5 , wherein the fittable and releasable fastener has a shaft portion, and the head combines moveably with the fitting and releasing piece by the shaft portion to make the head or the fitting and releasing piece turn against the shaft portion so that the fitting and releasing portion can perform fitting and releasing with the fitted and released portion.

7. The fittable and releasable fastener according to claim 5 , wherein the head or the fitting and releasing piece has an assembly positioning portion, and the assembly positioning portion can define the position of the fitted and released portion of the head or the fitting and releasing portion of the fitting and releasing piece as a damping position or limit of a direction.

8. The fittable and releasable fastener according to claim 5 , wherein the fitting and releasing portion or the fitted and released portion has a fitting and releasing surface and a stopping surface, a direction of the fitting and releasing surface is fittably and releasably turning, and a direction of the stopping surface is restrained from turning, or a force toward the direction of the stopping surface for fittably and releasably turning is enlarged.

9. A fittable and releasable fastener, the fittable and releasable fastener being placed in a carrier, a tool being used to pick up the fittable and releasable fastener from the carrier, after an assembly position of the fittable and releasable fastener and an object being compared through a comparison device, the fittable and releasable fastener being placed in the assembly position of the object.

10. The fittable and releasable fastener according to claim 9 , wherein the fittable and releasable fastener has a shaft portion, and the head combines moveably with the fitting and releasing piece by the shaft portion to make the head or the fitting and releasing piece turn against the shaft portion so that the fitting and releasing portion can perform fitting and releasing with the fitted and released portion.

11. The fittable and releasable fastener according to claim 9 , wherein the first combining portion or the second combining portion has a weldable surface, and the object or the another object has a soldering tin layer, the weldable surface and the soldering tin layer can be heated to perform welding, and the object or the another object is a circuit board.

12. The fittable and releasable fastener according to claim 9 , wherein the comparison device is an image comparison device, distance comparison device or computer comparison device.

13. The fittable and releasable fastener according to claim 9 , wherein the head or the fitting and releasing piece has an assembly positioning portion, and the assembly positioning portion can define the position of the fitted and released portion of the head or the fitting and releasing portion of the fitting and releasing piece as a damping position or limit of a direction.

14. A fittable and releasable fastener, comprising:
a head, having at least one fitted and released portion and a first combining portion; and
a fitting and releasing piece, having at least one fitting and releasing portion and a second combining portion, the head combining moveably with the fitting and releasing piece, the first combining portion and the second combining portion being respectively used to combine with an object and another object, and the fittable and releasable fastener being turned to make the fitting and releasing portion perform fitting and releasing with the fitted and released portion.

15. The fittable and releasable fastener according to claim 14 , wherein the fittable and releasable fastener has a shaft portion, and the head combines moveably with the fitting and releasing piece by the shaft portion to make the head or the fitting and releasing piece turn against the shaft portion so that the fitting and releasing portion can perform fitting and releasing with the fitted and released portion.

16. The fittable and releasable fastener according to claim 14 , wherein the fitting and releasing portion or the fitted and released portion has a fitting and releasing surface and a stopping surface, a direction of the fitting and releasing surface is fittably and releasably turning, and a direction of the stopping surface is restrained from turning, or a force toward the direction of the stopping surface for fittably and releasably turning is enlarged.
