[0002] The watch buckle is used to connect the watchband, facilitating the user to wear the watch on the wrist. Currently, the watchband buckles on the market are basically in the form of pin buckles or snap buttons, which require both hands to operate during the process. For young children, it is extremely inconvenient to wear, and basically they have to rely on their parents. However, when parents are not around or in other situations, they cannot wear the watch independently. It is very difficult for children to wear the watch by themselves, and the wearing process is rather troublesome and they cannot achieve independent wearing. The Chinese patent with the publication number CN111642869B provides a novel and convenient wearable watchband and a wearable device thereof. Among them, a novel and convenient wearable watchband includes a first strap, a second strap, and a watchband connection structure. The first strap passes through the watchband connection structure and is snap-connected to the watchband connection structure. A plurality of engaging positions are provided on the first strap. The second strap is connected to the watchband connection structure. The ends of the first strap and the second strap far from the connection structure are connected to the wearable device. Among them, the watchband connection structure includes: a housing, a suction member, a button, and an engaging member. In the contracted state, the engaging member is snap-connected to the engaging position under the action of the suction member. During the release process, the button can be pressed, and the button causes the engaging member to lose the acting force of the suction member, and the engaging member exits the engaging position. One-handed operation can be performed when locking or releasing, and the operation is very convenient and fast.

[0003] The above patent still has problems, resulting in a troublesome wearing process for children and unable to achieve independent wearing.
