[0042] The working principle of the buckle with guiding and limiting function in the utility model is as follows:

[0043] When the buckle with the guide limit function is used, the first buckle and the second buckle are brought close to each other, so that the mounting platforms jointly provided in the first buckle and the second buckle are brought close to each other. When the first buckle and the second buckle are brought close to each other to a certain distance, the magnets installed in the first buckle and the second buckle will attract each other through magnetic force until the mounting platforms contact each other, so that the first buckle and the second buckle can start sliding installation through the guide slide groove in the magnetic locking part. Under the action of the magnetic suction force, the first buckle and the second buckle are fully matched together, and the first buckle and the second buckle complete the buckle matching work through the locking boss;

[0044] When the first clip and the second clip are in contact with each other, the magnetic locking parts commonly provided in the first clip and the second clip will contact each other, and the first clip and the second clip will slide and guide each other through the installation groove, and the locking bosses in the first clip and the second clip will contact the upper surface of their corresponding installation platform. As the magnetic force of the magnets continues to attract each other, the first clip and the second clip will be driven to move relative to each other, and the locking bosses will quickly come into surface contact with the slope provided on the installation platform through the slope provided therein until the first clip is engaged. The fastener and the mounting platform surface in the second fastener are in contact with each other, and at this time, the installation slide guide space in the first fastener and the second fastener completely falls into each other's guide space, and under the attraction of the magnets, the first fastener and the second fastener are made to cooperate with the corresponding positioning boss on one side of the mounting platform, until the positioning step is completely matched with the clamping opening in the positioning boss, and at this time, the magnets are attracted together, and the magnets distributed up and down are on the same center line, and the first fastener and the second fastener are realized through the positioning boss to achieve the snap-fitting work;

[0045] When the first latch and the second latch need to be separated, the first latch and the second latch are pushed inward so that the first latch and the second latch both cooperate with the guide groove through the guide lip provided thereon, and the guide lip contacts the inwardly narrowed inclined surface of the tail of the wire groove. The first latch and the second latch will separate the mounting platform as they are pushed inward. Under continuous pushing, the guide grooves provided by the first latch and the second latch will contact each other and guide each other during separation, further improving the separation effect, overcoming the suction force brought by the magnet during the pushing process, so that the distance between their planes gradually increases as the pushing continues, until they are out of the suction range of the magnet, and the first latch and the second latch are completely separated.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
