Magnetic snap device

The invention relates to a clasping device, especially a clasping device that can be used for various daily necessities such as bags, backpacks, boxes, etc., and which can detachably connect two elements.

The bags in the prior art are usually opened and closed through zippers, and some specific bags (such as luggage) are further provided with a clasping device, which allows the zipper head to be inserted into it and fix the zipper head, so that the zipper It cannot be pulled to achieve the purpose of locking the luggage.

However, the disadvantage of the zipper device in the prior art is that when inserting the zipper slider into the zipper device, it is often necessary to accurately align the zipper slider with the insertion hole of the zipper device, and then a certain amount of force is required to insert the zipper slider into the zipper device. It is in the socket of the snap-fit device, so it is quite inconvenient to use.

In addition, both hands are required to open the buckle device. Specifically, one hand presses the buckle device to release the zipper head, but the zipper head will not automatically disengage from the buckle device at this time. And you have to use the other hand to pull out the zipper head. Therefore, it is necessary to use both hands when the fastener is to be opened, but this results in a great use restriction, and in many cases, it will cause considerable inconvenience.
