Abstract: The present disclosure provides a detachable buckle, including a belt head, a tail clamp, a fixing base, buckle buttons. One end of the fixing base is a hollow slot, the one end of the fixing base is connected with the tail clamp, and at least one socket is disposed on the one end of the fixing base. An opening is disposed on an edge of the hollow slot. Sliding grooves are disposed on both ends of the tail clamp, and the one end of the tail clamp is near the fixing base. Insert blocks sliding along the sliding grooves are disposed inside the sliding grooves. The insert blocks are connected with the buckle buttons, the buckle buttons drive the insert blocks to enter the hollow slot of the fixing base by pushing the tail clamp, and the buckle buttons are fixed with the sockets.

Abstract: The present disclosure provides a double-sided usable belt buckle, including a tail clamp, a frame, a buckling pin, first connectors, and a second connector. Both the frame and the buckling pin are connected with the tail clamp and rotate relative to the tail clamp, and a first end of the tail clamp is configured to connect with a belt body. The first connectors are configured to connect the tail clamp with the frame, the second connector is configured to connect the tail clamp with the buckling pin. A fixing base is disposed on a second end of the tail clamp, and the fixing base includes a left part fixing base and a right part fixing base. The left part fixing base and the right part fixing base are symmetrically disposed, a gap is formed between the left part fixing base and the right part fixing base.

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.

Abstract: A rotary belt buckle includes a belt fastener connection part, a belt connection part, and a spring mechanism. The belt connection part is connected with the belt fastener connection part through the spring mechanism, the belt connection part rotates around the belt fastener connection part; the belt fastener connection part has a slot, a strip unit which is located on the belt connection part fits with the slot; the belt connection part includes a cover plate and a box body, the strip unit includes an upper strip and a lower strip. The upper strip is located on the cover plate, and the lower strip is located on the box body. The upper strip is fixed with the lower strip to avoid the belt from being easily taken out of the belt buckle, to achieve a quick replacement of the belt, saving time of a user to replace the belt.
