## Abstract

A fastening device includes a fixing nut and a fixing base. The fixing base includes a base plate, an anti-falling wall, a door piece, and an anti-tilt arm. The anti-falling wall, the door piece and the anti-tilt arm are formed on the base plate, and the anti-tilt arm is arranged opposite to the door piece. An accommodation space is formed between the anti-falling wall, the door piece and the anti-tilt arm, and the fixing nut is rotatably arranged in the accommodation space. In addition, a heat dissipation module with the fastening device is also disclosed herein.

## Claims

### Claim 1

A fastening device, comprising:
a fixing nut; and
a fixing base, wherein the fixing base comprises:
a base plate;
an anti-falling wall formed on the base plate;
a door piece formed on the base plate; and
an anti-tilt arm, opposite to the door piece, formed on the base plate, wherein the anti-falling wall, the door piece and the anti-tilt arm form an accommodation space, and the fixing nut is rotatably disposed in the accommodation space.

### Claim 2 (depends on 1)

The fastening device of claim 1, wherein the fixing base further comprises an elastic claw formed on a surface, opposite to the anti-tilt arm, of the base plate.

### Claim 3 (depends on 1)

The fastening device of claim 1, further comprising at least one metal fixing hook movably mounted on the fixing base.

### Claim 4 (depends on 1)

The fastening device of claim 1, wherein the anti-tilt arm comprises a first flange protruding toward the fixing nut.

### Claim 5 (depends on 4)

The fastening device of claim 4, wherein the anti-falling wall comprises a second flange protruding toward the fixing nut.

### Claim 6 (depends on 5)

The fastening device of claim 5, wherein an anti-tilt arm height of the anti-tilt arm is equal to about 50% to 80% of a nut height of the fixing nut.

### Claim 7 (depends on 6)

The fastening device of claim 6, wherein an anti-falling wall height of the anti-falling wall is equal to about 30% to 50% of the nut height of the fixing nut.

### Claim 8 (depends on 7)

The fastening device of claim 7, wherein a door piece height of the door piece is equal to about 20% to 35% of the nut height of the fixing nut.

### Claim 9 (depends on 8)

The fastening device of claim 8, wherein a height difference between an anti-drop flange bottom height of the anti-falling wall and the door piece height is smaller than a flange height of the fixing nut.

### Claim 10

A heat dissipation module, comprising:
a base board;
a heat pipe disposed on the base board;
