Abstract: A portable inflatable diving float that includes an inflatable float body is revealed. The float body consists of a horizontal portion provided with a left folding area formed on the left side and a right folding area formed on the right side. After the left and the right folding area being folded to a middle portion of the float body, a left edge portion of the left folding area and a right edge portion of the right folding area are connected by a first connection member and kept in the folded state. A flat body formed after deflation of the float body becomes a backpack body with smaller area. At least one strap member is connected between the top end and the bottom end on a front side or a back side of the float body so that users can carry the backpack body on their back.

Abstract: A quick release buckle is revealed. The quick release buckle includes a male member, a female member and a pulling member. The male member consists of two symmetrical legs that can be deformed elastically and a U-shaped part disposed between the two legs. Two ends of one side of the U-shaped part with an opening are respectively connected to each of the two legs. The female member is inserted by and locked with the male member while the pulling member is connected to the U-shaped part of the male member. When users pull the pulling member out, two ends of the U-shaped part with the opening are deformed inward. Thus the two legs are further driven to be deformed inward. Therefore the male member is pulled out of the female member.
