1. A lens module for use in a camera, comprising:
a fixed component;
a moving part movably arranged on the fixed component and comprising a lens holder for fixing a lens and driving the lens to move in the direction of an optical axis to realize focusing, and a movable frame for fixing an image sensing unit and driving the image sensing unit to move to realize image stabilization;
a focusing drive mechanism for driving the lens holder to move relative to the fixed component, and/or an image stabilization drive mechanism for driving the movable frame to move relative to the fixed component;
wherein one of the fixed component and the moving part is provided with an accommodating cavity with an opening, the other is provided with a protrusion, which is inserted into the accommodating cavity from the opening in a first direction and is able to move in the accommodating cavity, the accommodating cavity has a first surface spaced apart from the protrusion in the first direction and a first side face extending from a periphery of the first surface in the first direction, and the protrusion has a second surface spaced apart from the first surface and a second side face extending from the second surface in the first direction; and
a dust absorption gel arranged on the first surface and sealing a gap between the first surface and the second surface, or arranged on the second side face and sealing a gap between the first side face and the second side face.
