Fixing mechanism and lamp

Abstract

A fixing mechanism comprises a casing, a plurality of clamping members, and a biasing member respectively configured in the casing. The casing includes an inner surface and surrounds an accommodating space, and the accommodating space has a large-diameter end and a small-diameter end. The plurality of clamping members are configured in the accommodating space, and each clamping member has an outer surface facing the inner surface. A cross section of the outer surface along the axial direction is arc-shaped and the outer surface of the clamping member contacts with the inner surface of the casing partially. The clamping members can be pushed toward the large-diameter end of the accommodating space to separate the clamping members from each other, so that the wire can move between the clamping members. The biasing member is disposed in the accommodating space and located on one side of the large-diameter end. The biasing member can push the clamping members toward the small-diameter end of the accommodating space to make the clamping members close to each other to clamp the wire. Therefore, the contact area and friction force between the clamping members and the inner surface of the casing can be reduced, and the convenience of the operation can be improved. The invention also provides a lamp using the fixing mechanism.
