AI Technical Summary
Existing cold-proof earmuffs are not adjustable in size, cannot adapt to different usage needs, and the insulation components are not easy to disassemble, maintain, or replace.
Pulling the rope causes the limiting block to retract into the mounting base, adjusting the size of the arc-shaped connector. Stability is achieved using the telescopic spring and limiting hole. During disassembly, pulling the annular connecting base separates the limiting spring from the limiting groove, facilitating the replacement of the insulation component.
The adjustable size of the earmuffs allows for different needs to be met, ensuring the stability of the earmuffs and facilitating the disassembly and maintenance of the insulation components.
