Retractable support and lighting fixture

A lighting fixture, comprising a retractable support;

• wherein the retractable support comprises a main rod body, a support assembly, and a functional assembly;
• wherein the support assembly is disposed on a first end of the main rod body, the functional assembly is retractably disposed on a second end of the main rod body, and the main rod body internally defines an accommodation cavity suitable for accommodating the functional assembly;
• wherein the functional assembly comprises a first rotatable seat, at least one second rotatable seat, at least one third rotatable seat, and at least one functional module;
• the first rotatable seat is connected to the main rod body;
• the at least one second rotatable seat and the at least one third rotatable seat are arranged in a one-to-one correspondence;
• for each of the at least one second rotatable seat, the second rotatable seat is rotatably disposed on the first rotatable seat about a first rotation axis, and a corresponding one of the at least one third rotatable seat is rotatably disposed on the second rotatable seat about a second rotation axis;
• each of the at least one functional module is disposed on a corresponding one of the at least one third rotatable seat;
• each of the at least one functional module is rod-shaped;
• an axial direction of the first rotation axis is perpendicular to an axial direction of the main rod body, and an axial direction of the second rotation axis is perpendicular to the axial direction of the first rotation axis;
• wherein the at least one second rotatable seat is at least two second rotatable seats that are arranged side by side along the axial direction of the first rotation axis;
• the at least one third rotatable seat is at least two third rotatable seats that are arranged in a one-to-one correspondence with the at least two second rotatable seats, and the at least one functional module is a plurality of functional modules to be matched with the at least two third rotatable seats;
• wherein the functional module comprises a main body of the lighting fixture.
