When the buckling component 5 is buckled to the limiting hole 153, the plug 55 presses against the button 73 to make the button 73 move in the direction of extending out of the pressing hole 715.

[0058] In this embodiment, by adding a release assembly 7, the button 73 of the release assembly 7 and the plug 55 are pressed and matched, and the plug 55 is extended under the action of the spring 533 to be buckled and matched with the limiting hole 153, and drives the button 73 to move outward. When the release is required, by pressing the button 73, the plug 55 slides out of the limiting hole 153, and the spring 533 is compressed, which facilitates the disassembly of the spring arm assembly 3. Therefore, by directly pressing the button 73, this solution is conducive to further improving the disassembly efficiency of the spring arm assembly 3.

[0062] In summary, in the past, the fixing method of the spring 533 arm 331 used an elastic retaining ring for the shaft, which was difficult to install. The shadowless lamp 10 of the embodiment of the utility model upgrades the fixing method of the spring 533 arm 331 to a button 73 lock, which is convenient and efficient to install. Specifically, an elastic pin assembly is embedded in the adapter assembly 31, and the button 73 assembly is installed on the outer side of the hole wall of the adapter hole 151. When the adapter assembly 31 is concentrically inserted into the adapter hole 151, the built-in elastic pin assembly is squeezed inwardly, and when the plug 55 is concentric with the button 73 assembly, the elastic pin is released from compression and the button is ejected, thereby realizing the buckle connection between the spring arm assembly 3 and the rotating arm assembly 1. Therefore, the solution of the utility model facilitates the installation and disassembly of the spring arm assembly 3 of the shadowless lamp 10, saving the assembly time of the workers.
