It is difficult to adjust the length of the belt with one hand.

Also, it is difficult for belt length adjusting means using a hook-and-loop fastener to immobilize the hook-and-loop fastener while tightening the belt with one hand. In addition, since a home-use sphygmomanometer is often used alone, it is necessary for the user to wear the sphygmomanometer on his / her own wrist, and to hold the sphygmomanometer in a predetermined position with one hand. .

Accordingly, in order for the user to wear the sphygmomanometer alone, the sphygmomanometer is applied to a predetermined position on the wrist, the belt is wrapped around the wrist with one hand, and the sphygmomanometer is fixed between the wrist and the body. Tips such as tightening the belt and wearing a coat are necessary, and it has been particularly difficult for an elderly person or a physically handicapped person who needs a sphygmomanometer to wear the sphygmomanometer by himself.

In addition, the length of the belt cannot be adjusted when the hook-and-loop fastener is surfaced. In order to adjust the length of the belt, it is necessary to remove the hook-and-loop fastener, retighten it, and re-attach. And it was difficult to finely adjust the length of the belt.

Accordingly, an object of the present invention is to provide a buckle that can easily adjust the belt length and clamp and release the belt with one hand, and can securely clamp the belt.
