  • Patent number: 11096454
    Abstract: The present invention provides a double-sided usable belt buckle, a belt having the double-sided usable belt buckle can be available on both sides. The two ends of the pin shaft can be connected with the buckle and the tail clamp by matching the clamping block arranged on the pin shaft with the clamping groove. The clamping block extends into the pin shaft mounting hole firstly, and after the connecting convex block is clamped into the connecting groove, the clamping block can be clamped into the clamping groove. When it is needed to use the other side of the belt having the double-sided usable belt buckle, simply pressing the pin shaft to make the clamping block slide out of the clamping groove so as to separate the tail clamp from the buckle, and then replace the tail clamp and connect it with the buckle again.
