A buckle structure includes a buckling base and a buckling shaft. An axial hole is defined in the buckling base, an axial channel extending along an axial direction of the axial hole and a circumferential channel extending along a circumferential direction of the axial hole are defined on an internal surface of the axial hole, an opening is defined at an end of the axial channel and the other end of the axial channel communicates with the circumferential channel, the axial channel is provided with a movable block blocking between the axial channel and the circumferential channel and able to selectively retreat from the axial channel and the circumferential channel. The buckling shaft is inserted in the axial hole; a latch protruding from a lateral surface of an end of the buckling shaft is able to move through the opening and along the axial channel and the circumferential channel.
