The light source assembly 20 includes a base 21 installed at one end of the movable chamber 11, a bracket 22 installed on the base 21, and a light source 23 disposed between the base 21 and the bracket 22.
The base 21 is screwed to one end of the movable chamber 11.
The bracket 22 is connected with the base 21 in a buckling manner, so that the bracket 22 cannot easily fall off in the installation process, and the installation efficiency is improved.
The light source 23 is a COB light source.
The light source assembly 20 further comprises a fixing ring 24 and a plurality of steel balls 25, the fixing ring 24 and the steel balls 25 are arranged between the base 21 and the first resetting piece 50, the surface of the base 21 is provided with a plurality of steel ball grooves 211 which are arranged along the circumferential direction of the base 21, the steel balls 25 are arranged in the steel ball grooves 211 one by one, and the fixing ring 24 is matched with the surface of each steel ball 25 and is connected with the first resetting piece 50. The steel balls 25 are arranged, so that the fixing ring 24 can rotate more smoothly and can be operated more easily, and the hand feeling of the product during adjustment is optimized.
