## Abstract

A head-mounted display device includes a body, a first clamping part, a second clamping part and a sliding part. The body has a lens holder and two optical lens sets. The lens holder is used for accommodating a first lens and a second lens corresponding to both eyes. The first clamping member is disposed on the body and has a first free end portion. The second clamping member is disposed on the body and has a second free end portion. The sliding part is slidably disposed on the body and between the first free end portion and the second free end portion. When the sliding part slides along a first direction from an initial position, it first pushes the first free end portion and the second free end portion to make them abut against the first lens and the second lens respectively, and then pushes the first free end portion and the second lens portion to make them drive the first lens and the second lens to move respectively to change the distance from the body.

## Claims

### Claim 1

A head-mounted display device, comprising:
a body, having a lens holder and two optical lens sets, wherein the lens holder is used for accommodating a first lens and a second lens corresponding to both eyes;
a first clamping part, disposed on the body and has a first free end portion, wherein the first clamping part is used to contact the first lens;
a second clamping part, disposed on the body and has a second free end portion, wherein the second free end portion is used to contact the second lens; and
a sliding part, slidably disposed on the body and between the first free end portion and the second free end portion, wherein when the sliding part slides along a first direction from an initial position, it first pushes the first free end portion and the second free end portion to make them abut against the first lens and the second lens respectively, and then pushes the first free end portion and the second lens portion to make them drive the first lens and the second lens to move respectively to change the distance from the body.

### Claim 2 (depends on 1)

The head-mounted display device according to claim 1, wherein the first clamping part, the second clamping part and the lens holder are integrally formed.

### Claim 3 (depends on 1)

The head-mounted display device according to claim 1, wherein the first free end portion has a first inclined surface and a third inclined surface, the second free end portion has a second inclined surface and a fourth inclined surface, when the sliding part slides along the first direction from the initial position, it first contacts the first inclined surface and the second inclined surface, and then contacts the third inclined surface and the fourth inclined surface.

### Claim 4 (depends on 1)

The head-mounted display device according to claim 1, further comprises a first friction part and a second friction part, respectively disposed on the first free end portion and the second free end portion and used to contact the first lens and the second lens.

### Claim 5 (depends on 1)

The head-mounted display device according to claim 1, wherein a moving direction of the first lens and the second lens are perpendicular to the first direction.
