Description

The present application claims the priority of the Chinese Patent Application No. 202321676448.6, filed on June 29, 2023, titled as "Fixing Structure and Lamp", the disclosure of which is incorporated herein by reference in its entirety as part of the present application. TECHNICAL FIELD The present application relates to the technical field of lighting equipment, in particular to a fixing structure and a lamp. BACKGROUND Typically, in lamp design, it is often necessary to use a power cord flexible cable SR (Strain Relief) to connect the lamp body and the power cord. To ensure the reliability and safety of the power cord, a fixing method is required to clamp it inside the lamp. Currently, the commonly used method on the market is to utilize the plastic deformation of the SR plastic to force the power cord flexible cable SR into a wire clamping device. However, this method has some difficulties and limitations, such as the power cord flexible cable SR being difficult to penetrate the wire clamping device and high pulling-in difficulty, which in turn affect the fixing efficiency, reliability, and safety. CN215523191U proposes a lamp bracket and a lamp. By arranging an extension bracket protruding from the lamp bracket and an installation hole on the extension bracket, the extension bracket prevents the tail card wire from detaching from the installation hole to avoid the tail card wire being pulled off. However, the extension bracket needs to be separately protruded outward on the bracket body, resulting in a complex structure and occupying additional space, which is not conducive to the miniaturization of the entire product. Moreover, after the tail card wire is electrically connected to the light-emitting component, it needs to be bent to install the tail card wire into the extension bracket, increasing the assembly difficulty. In view of foregoing, it is necessary to provide a fixing structure and a lamp to solve the above problems.
