The invention discloses a shoelace tightening buckle. The traditional shoelace tying method is complicated, the tied shoelace becomes untied easily and needs to be tied again, the operation is extremely troublesome, aiming at the abovementioned defects, the following preferable improvement is made: the shoelace tightening buckle comprises a base and an upper cover arranged on the base, wherein the upper cover and the base are in threaded connection through a screw fixed to the center of the upper cover, a clamping ring body sleeves the screw, a screw base in threaded match with the screw is arranged in the center of the base, a shoelace tightening buckle sleeves the screw base, and two through holes which are connected to the shoelace tightening buckle are formed in the base. The shoelace tightening buckle is simple in structure, the shoelace passes through the through holes in the base, the upper cover is rotated, the upper cover drives a one-way buckle to rotate, then the shoelace tightening buckle is driven to rotate, so that the automatic tightening of the shoelace is realized, the complicated tying operation is not needed, meanwhile, the tightened shoelace can not become loosened due to long time, and the operation is extremely convenient.
