[0015] As Figures 1 to 9 shown, a safety buckle includes a fastener assembly 10 and a buckle assembly 20. A protruding connecting column 11 is provided at the center of the fastener assembly 10, and a locking groove 12 is provided on the outer periphery of the connecting column 11. The buckle assembly 20 includes a housing 21, an operating member 22 and a locking member 23. The operating member 22 includes a button portion 24 and an elastic portion 25. The elastic portion 25 on one side of the operating member 22 is arranged in the housing 21, and the button portion 24 on the other side extends to the outside of the housing 21. The locking member 23 includes a pair of fastening portions 26 and a pair of protruding movable portions 27. The locking member 23 is arranged inside the housing 21. The pair of fastening portions 26 are arranged on the side of the opening 28 of the housing 21. The elastic portion 25 is arranged on the side of the locking member 23. The movable portion 27 abuts against the side wall of the elastic portion 25. When the button portion 24 is pressed and the elastic portion 25 is deformed by extrusion, the movable portion 27 moves along the elastic portion 25 to move the two fastening portions 26 away from each other relatively outward. When the extrusion of the elastic portion 25 stops, the two fastening portions 26 approach each other and thus fall into the locking groove 12 of the connecting column 11 to complete the locking.

[0016] When the fastener assembly 10 and the buckle assembly 20 need to be buckled and connected, press the connecting column 11 of the fastener assembly 10 to insert it into the housing 21 along the opening 28. The buckling portion 26 of the locking member 23 in the housing 21 falls into the locking groove 12 of the connecting column 11, so that the fastener assembly 10 and the buckle assembly 20 are buckled and connected. When the fastener assembly 10 and the buckle assembly 20 need to be unlocked, press the button portion 24 in the buckle assembly 20. The button portion 24 squeezes the elastic portion 25 to contract, and the movable portions 27 on both sides of the locking member 23 abut on the surface of the elastic portion 25. The squeezed and contracted elastic portion 25 pushes the movable portions 27 on both sides to move outward, and at the same time drives the two buckling portions 26 to leave the locking groove 12. At this time, the fastener assembly 10 and the buckle assembly 20 are in an unlocked state and can be separated to complete disassembly. Therefore, by pressing the button portion 24, the elastic portion 25 is used to push the locking member 23 to expand or retract, so as to control the locking and unlocking between the locking assembly 20 and the buckling assembly 10.
