## Abstract

An object-connecting device includes an engaging member having a perforation, a first sleeve having a first axial hole, a first abutting surface, and a first recess, a second sleeve passing through the perforation, a bolt passing through the first axial hole and the second axial hole, and a retaining ring. The second sleeve has a second axial hole, a second abutting surface, and a second recess, wherein the second axial hole communicates with the first axial hole. The second abutting surface abuts against the first abutting surface. The second recess matches with the first recess to form a receiving groove. The retaining ring is disposed in the receiving groove and is fastened on the bolt. With the aforementioned design, the bolt could be prevented from disengagement.

## Claims

### Claim 1

An object-connecting device, comprising:
an engaging member having a perforation;
a first sleeve having a first axial hole, a first abutting surface, and a first recess;
a second sleeve which passes through the perforation and has a second axial hole, a second abutting surface, and a second recess, wherein the second axial hole communicates with the first axial hole; the second abutting surface abuts against the first abutting surface; the second recess matches with the first recess to form a receiving groove;
a bolt passing through the first axial hole and the second axial hole; and
a retaining ring which is disposed in the receiving groove and is fastened on the bolt.

### Claim 2 (depends on 1)

The object-connecting device of claim 1, wherein the bolt has a head and a body; the head abuts against a top surface of the first sleeve; the body passes through the first axial hole and the second axial hole and has an annular groove for receiving the retaining ring.

### Claim 3 (depends on 1)

The object-connecting device of claim 1, wherein the first recess is recessed into a wall of the first axial hole adjacent to an edge of the second sleeve, and the second recess is recessed into a wall of the second axial hole adjacent to an edge of the first sleeve.

### Claim 4 (depends on 1)

The object-connecting device of claim 1, wherein the first abutting surface and the second abutting surface are tight fitted.

### Claim 5 (depends on 1)

The object-connecting device of claim 1, wherein the first abutting surface and the second abutting surface are screw fitted.

### Claim 6 (depends on 1)

The object-connecting device of claim 1, wherein the second sleeve has a base and a body portion connected to the base; the base abuts against the engaging member; the body portion passes through the perforation and partially enters the first axial hole, wherein a portion of the body portion that enters the first axial hole has the second recess.

### Claim 7 (depends on 1)

The object-connecting device of claim 1, wherein the receiving groove is located within a projection area of the first sleeve in a radial direction of the first sleeve.

### Claim 8 (depends on 1)

The object-connecting device of claim 1, wherein the first recess is a chamfer, and the second recess is also a chamfer.
