The present invention provides a magnetic fastener composed of a female snap and a male snap. The female snap includes a first locking unit, the male snap contains a second locking unit, and the first locking unit has a projecting piece, on which there is the clamping groove; the male snap contains a base with a clamping hole; the projecting piece passes through the clamping hole. The second locking unit includes a locking arm and a clamping portion, and can move on the base to drive the movement of the locking arm so that the clamping portion is kept away from the clamping groove to unlock the second locking unit. The present invention also discloses a strap that use magnetic fastener for locking and unlocking, which is simple and convenient.

A magnetic fastening buckle includes a male and a female buckle member that can be moved toward and engaged with each other by magnetic attraction between two magnets separately provided thereon; and an anti-separation member movably connected to the male buckle member. When the anti-separation member is located at an unlocking position, it does not overlap the female buckle member, allowing the male buckle member to move rearward in a y-axis direction to separate from the female buckle member. When the anti-separation member is moved in an x-axis direction to a locking position, it can overlap the female buckle member. In this position, the anti-separation member can overlap the female buckle member when the male buckle member is pushed toward a rear removal opening, so as to prevent the male buckle member from separating from the female buckle member, allowing the two buckle members to remain engaged with each other.

The present invention provides a sofa barrier, suitable for the horizontal gap between a sofa base and a floor, comprising at least one elongated panel-shaped barrier panel, horizontally positioned to effectively prevent objects or pets from entering beneath the sofa. The core technology lies in a male-female buckle, including a male buckle, a female buckle, a plug, and a slot, which secure the barrier panel in place between the sofa base and the floor through tight interlocking. This ensures stability during daily use, making it resistant to loosening or collapsing. This design does not require the use of glue, avoiding damage to the floor surface, and offers high stability and durability, making it difficult for pets to destroy.

A magnetic attraction buckle is provided, which includes a first body and a second body that are cooperated and engaged with each other. The first body is provided with a clamping part that is protruded, the clamping part is provided with a first magnetic piece. The second body is provided with a clamping groove that accommodates the clamping part. The second body is internally provided with a movable locking piece, and the locking piece is provided with a second magnetic piece that attracts the first magnetic piece when locked and a third magnetic piece that repels the first magnetic piece when unlocked. This application effectively solves a technical problem of inconvenient one-handed operation of existing webbing buckles.
