Technical Field

[0001] The utility model relates to the field of hair styling tools, in particular to a head-changing structure of hair styling tools. Background Art

[0002] With the improvement of living standards and the enhancement of beauty and hair styling awareness, more and more families begin to equip professional hair styling tools to meet the needs of daily self-care and simple styling. These hair styling tools, such as hair dryers, curling irons, straightening irons, curling combs, hot air combs, etc., have become indispensable daily necessities in modern families. However, due to the diverse pursuit of hair styling effects by people, household hair styling tools need to have more flexible functions to meet different needs. Therefore, the design of household hair styling tools that can replace different functional heads or functional heads of different specifications is particularly important.

[0003] At present, although there are a wide variety of household hair styling tools on the market, most of the products have relatively single functions and cannot meet the diverse hair styling needs of users. Some high-end products also provide a variety of accessories or replaceable parts, which can share a main body with a handle and are designed to have a structure that can replace different functional heads or different specifications. By operating by the user to replace different functional heads, the function of multi-purpose use of one machine is realized to enhance the user experience.

[0004] By adopting a head-changing structure, the quick connection and disassembly of the functional head should be able to be realized, without complex operations or additional tools, enabling users to easily replace the required functional head to meet different hair styling needs. In the prior art, the head-changing structure of the functional head is usually realized by a pin and a metal snap ring connected thereto. By pressing a button to drive the pin, the quick connection or quick detachment of the metal snap ring and the pin is realized. However, this head-changing structure is not stable enough and is prone to loosening after long-term use, and the connection between the pin and the metal snap ring is not smooth enough, and the phenomenon of incomplete clamping is likely to occur during operation, thus affecting quick locking and quick unlocking. Seriously, the functional head may even fall off, posing a safety hazard to users. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above defects, and provide a head-changing structure of a hair styling tool, which can realize quick unlocking, and the overall operation is simple, the structure is stable and not easy to loosen, solving the technical problems of unstable unlocking structure and easy loosening in the prior art.
