AI Technical Summary
The existing snap-fit structure cannot effectively position the limiting block, resulting in an unstable and weak connection that is prone to separation due to external force or negligence.
A wedge-shaped limiting block was designed, with a positioning groove on the inclined surface of the limiting block. The limiting port and the positioning groove form a bidirectional positioning structure, and a stable connection between the limiting block and the limiting port is achieved by rotation.
It improves the stability and security of the connection, ensuring that the buckle is not easily separated during use and enhancing the strength of the connection.

Abstract
Claims
1. A novel firm buckle, comprising a limiting block and a limiting port arranged separately on a first component and a second component, the first component and the second component being rotatably inserted and fitted, characterized in that, The limiting block is constructed as a wedge shape with its thickness gradually increasing from one end to the other in the rotational direction. A positioning groove is formed on the slope surface of the limiting block. The limiting opening is provided with a positioning block extending inward in the insertion direction corresponding to the positioning groove. The distance between the positioning block and the side wall of the limiting opening is at least equal to the distance between the positioning groove and the end wall of the limiting block. The limiting opening can slide along the slope surface to pass over the limiting block, so that the side wall of the limiting opening can abut against the end wall of the limiting block, and the positioning block can abut against the groove wall of the positioning groove.
2. The novel secure fastener of claim 1, wherein, The positioning groove is a wedge-shaped groove, and the direction of thickness increase of the positioning groove is the same as the direction of thickness increase of the limiting block.
3. The novel secure fastener of claim 2, wherein, One side of the positioning groove coincides with one side of the limiting block, and the extension height of the positioning groove is less than the extension height of the limiting block.
4. The novel secure fastener of claim 3, wherein, An arc-shaped transition surface is provided between the end wall of the limiting block and the slope surface.
5. The novel secure fastener of claim 1, wherein, The limiting block is disposed adjacent to the plug end of the first component, and the number of the limiting blocks is at least two and they are centrally symmetrically distributed on the outer wall of the plug.
6. The novel secure fastener of claim 5, wherein, The limiting port is located near the bottom of the slot of the second component, and the number of the limiting ports is the same as the number of the limiting blocks and they are centrally symmetrically distributed on the outer wall of the slot.
7. The novel secure fastener of claim 6, wherein, The plug is cylindrical in shape, the slot is adapted to the shape of the plug, and the slot is also provided with a clearance groove that can pass through the limit block at the position corresponding to the limit block. The clearance groove is arranged adjacent to the limit port.
