## Abstract

The present disclosure provides a pressing ring and a lens module. The pressing ring includes an annular body; and first and second sheared edges formed on the annular body. The body includes an inner side wall around an optical axis and forming a light through hole, an object-side wall extending from an edge of the inner side wall in a direction facing away from optical axis, an image-side wall opposite to the object-side wall and extending from an edge of the inner side wall in a direction facing away from the optical axis, and an outer side wall extending from an edge of the object-side wall facing away from the inner side wall to the image-side wall. The object-side wall includes an abutting surface surrounding the inner side wall and connected to the inner side wall, and a glue-dispensing groove surrounding and connected to the abutting surface.

## Claims

### Claim 1

A pressing ring, comprising:
an annular body forming a light through hole;
a first sheared edge formed on the annular body; and
a second sheared edge formed on the annular body,
the body comprises an inner side wall around an optical axis and forming the light through hole, an object-side wall extending from an edge of the inner side wall close to an object side in a direction facing away from the optical axis, an image-side wall opposite to the object-side wall and extending from an edge of the inner side wall close to an image side in a direction facing away from the optical axis, and an outer side wall extending from an edge of the object-side wall facing away from the inner side wall to the image-side wall; the object-side wall comprises an abutting surface surrounding the inner side wall and connected to the inner side wall, and a glue-dispensing groove surrounding the abutting surface and connected to the abutting surface; and each of the first sheared edge and the second sheared edge is located in the glue-dispensing groove.

### Claim 2 (depends on 1)

The pressing ring as described in claim 1, wherein the glue-dispensing groove comprises a first side surface extending from an edge of the object side wall facing away from the optical axis in a direction facing towards the optical axis, and a second side surface extending from an edge of the first side surface facing away from the object-side wall in a direction facing away from the optical axis; and the first sheared edge and the second sheared edge are located at the second side surface.

### Claim 3 (depends on 1)

The pressing ring as described in claim 1, wherein the inner side wall comprises a first surface extending from an edge of the abutting surface close to the optical axis in a direction facing away from the object side and facing towards the optical axis, a second surface extending from an edge of the first surface facing away from the abutting surface in a direction facing towards the image side and facing away from the optical axis.

### Claim 4 (depends on 3)

The pressing ring as described in claim 3, wherein the image-side wall comprises a first side wall extending from an edge of the second surface facing away from the optical axis in a direction facing away from the optical axis, a second side wall extending from an edge of the first side wall facing away from the optical axis in a direction facing towards the object side and facing away from the optical axis, and a third side wall extending from an edge of the second side wall facing away from the first side wall in a direction facing away from the optical axis, the third side wall being connected to the outer side wall.

### Claim 5 (depends on 1)

A lens module, comprising the pressing ring as described in claim 1.

### Claim 6 (depends on 5)

The lens module as described in claim 5, wherein the glue-dispensing groove comprises a first side surface extending from an edge of the object side wall facing away from the optical axis in a direction facing towards the optical axis, and a second side surface extending from an edge of the first side surface facing away from the object-side wall in a direction facing away from the optical axis; and the first sheared edge and the second sheared edge are located at the second side surface.

### Claim 7 (depends on 5)

The lens module as described in claim 5, wherein the inner side wall comprises a first surface extending from an edge of the abutting surface close to the optical axis in a direction facing away from the object side and facing towards the optical axis, a second surface extending from an edge of the first surface facing away from the abutting surface in a direction facing towards the image side and facing away from the optical axis.

### Claim 8 (depends on 7)

The lens module as described in claim 7, wherein the image-side wall comprises a first side wall extending from an edge of the second surface facing away from the optical axis in a direction facing away from the optical axis, a second side wall extending from an edge of the first side wall facing away from the optical axis in a direction facing towards the object side and facing away from the optical axis, and a third side wall extending from an edge of the second side wall facing away from the first side wall in a direction facing away from the optical axis, the third side wall being connected to the outer side wall.
