Lens module and electronic device

A lens module, comprising a lens barrel and an optical component, wherein the lens barrel includes a barrel wall and a receiving cavity;

• the barrel wall includes a first inner side wall near an optical axis and a first outer side arranged opposite to the first inner side wall, a receiving cavity for accommodating the optical component is surrounded by the first inner side wall;
• the optical component includes an object side, an image side arranged opposite to the object side, and an outer side connecting the object side and the image side and far from the optical axis, and the optical component includes a first optical member;
• the lens barrel further includes a clamping member protruding from the first inner side wall, and the clamping member is extended in a direction from an object side to an image side;
• the clamping member includes a second inner side wall close to the optical axis;
• the second inner side wall of the clamping member is a sloped surface on a section paralleled to the optical axis, and the sloped surface is inclined from the object side to the image side toward a direction close to the optical axis;
• the second inner side wall is resisted against the outer side of the first optical member;
• wherein the clamping member is provided with at least one notch on a side close to the image side, and in the radial direction of the barrel wall, each notch is extended from the second inner side wall toward a direction far from the optical axis.
