## Abstract

A fastening apparatus includes a body; a fastener movably disposed at the body; and a resilient component disposed at the body, the resilient component having an end abutting against the body and another end abutting against the fastener such that the resilient component allows the fastener to be protruded from or inserted into the body normally, or the fastener in rotation and the resilient component interact with each other to effectuate limiting-stopping, interfering-stopping or interfering-abutting. The fastener enters the body disposed on the first object and compresses the resilient component. Then, the resilient component protrudes the fastener out of the body, thereby fastening the fastener to the second object quickly. Easy separation of the first and second objects entails moving the fastener into the body. A fastening method for the fastening apparatus is further introduced.

## Claims

### Claim 1

A fastening apparatus, comprising:
a body;
a fastener movably disposed at the body; and
a resilient component disposed at the body;
wherein the body has a receiving region for receiving the fastener and the resilient component, a whole width of the fastener is less than a whole width of the receiving region, the body is configured to pass through a through-hole of an object, the resilient component having an end abutting against the body and another end abutting against the fastener such that the resilient component applies a force in a direction away from the receiving region of the body to urge the fastener to be protruded away from the receiving region of the body to engage with an edge of the through-hole of the object.

### Claim 2 (depends on 1)

The fastening apparatus of claim 1, wherein the body has a connecting portion for connecting the body to the first object.

### Claim 3 (depends on 1)

The fastening apparatus of claim 1, wherein the fastener has a fastening portion and pivotal connection portion, the fastening portion extending out of the body, allowing the pivotal connection portion and the body to be movably coupled together.

### Claim 4 (depends on 3)

The fastening apparatus of claim 3, wherein the fastening portion has a guiding surface and an abutting surface and is arcuate or bent.

### Claim 5 (depends on 4)

The fastening apparatus of claim 4, wherein the resilient component fits around the pivotal connection portion.

### Claim 6 (depends on 1)

The fastening apparatus of claim 1, wherein the resilient component is a torsional spring, or the resilient component is integrally formed with the fastener or the body.

### Claim 7 (depends on 2)

The fastening apparatus of claim 2, wherein the connecting portion has a material admitting space for admitting a material of the first object such that the connecting portion and the first object are coupled together.

### Claim 8 (depends on 1)

The fastening apparatus of claim 1, wherein the fastening apparatus is disposed at a carrier, the carrier being a cord or a tray or having a lid.

### Claim 9 (depends on 1)

The fastening apparatus of claim 1, wherein the resilient component is implemented as a combination of an elastomer and a pusher.

### Claim 10 (depends on 9)

The fastening apparatus of claim 9, wherein the pusher extends to form an engaging portion, and, depending on motion of the fastener, the engaging portion pushes the pusher such that the pusher protrudes from or retreats into the body.

### Claim 11 (depends on 10)

The fastening apparatus of claim 10, wherein the fastener has a limiting portion for limiting a position of the pusher, thereby causing the fastener to stay at a pushed position or causing the pusher to stay at a pushed position.

### Claim 12 (depends on 11)

The fastening apparatus of claim 11, wherein the engaging portion is columnar, threaded, externally engaging or internally engaging.

### Claim 13 (depends on 12)

The fastening apparatus of claim 12, wherein the limiting portion is concave, convex, columnar, planar, layered, arcuate or curved, or the pusher is concave, convex, columnar, planar, layered, arcuate or curved.

### Claim 14 (depends on 1)

The fastening apparatus of claim 1, wherein the fastener in rotation abuts against, or is abutted against by, the resilient component and thus normally or temporarily tends to be upright or tends to protrude upright or tends to lie laterally or tends to protrude laterally.

### Claim 15 (depends on 1)

The fastening apparatus of claim 1, wherein the fastener has an operating portion for controlling the fastener to rotate or move.

### Claim 16 (depends on 2)

The fastening apparatus of claim 2, wherein the body has a stamping surface to be pressed under an applied force to sink the connecting portion into the first object, so as to effect connection.

### Claim 17 (depends on 2)

The fastening apparatus of claim 2, wherein the body has higher rigidity than the first object, whereas the connecting portion of the body has a squeezing portion and a material admitting space, and the squeezing portion squeezes a material of the first object such that the material enters or flows into the material admitting space.

### Claim 18 (depends on 17)

The fastening apparatus of claim 17, wherein the stamping surface flanks the fastener, lies outside the fastener, lies above the body, or surrounds the body.

### Claim 19 (depends on 1)

The fastening apparatus of claim 1, wherein the fastener has a limiting portion such that the limiting portion and the resilient component limit a position of the fastener, or the limiting portion determines a position which the fastener stays at.

### Claim 20 (depends on 19)

The fastening apparatus of claim 19, wherein the limiting portion is concave, convex, columnar, planar, layered, arcuate or curved.

### Claim 21 (depends on 1)

A fastening method for a fastening apparatus, requiring the fastening apparatus of claim 1 and a second object, comprising moving the second object downward into a fastening range of the fastener and then allowing the fastener resiliently protruded to engage with the second object or allowing the fastener inserted to move upward and thus disengage with the second object.
