[0002] Rail fasteners are key components used to connect rails and sub-rail components in railway projects. They include clips, spring bars and other parts. They can firmly fix rails, disperse train loads and maintain standard track gauges. They ensure the stability and safety of railway lines and prevent rails from moving or shifting. They are an indispensable part of railway transportation.

[0003] The utility model with the authorization publication number CN209686165U provides a rail fastener system, which belongs to the technical field of "rail fasteners", and the protected claim is: "It includes an elastic pad, an iron pad and a rail pad sequentially laid on the elastic pad, and a spiral spike fixing the iron pad to the sleeper, and a buckle arm extending upward in a mirrored manner and bent toward the symmetric center on the surface of the iron pad below both sides of the rail pad; a pin groove is provided on the inner surface of the buckle arm, and a stop block is inserted in the space formed by the bending of the buckle arm, and the stop block is provided with a pin groove corresponding to the pin groove. The locking groove is inserted into the space between the pin groove and the locking groove by a locking pin; the screw hole for the spiral spike to pass through the fixed iron pad is arranged on the surface of the iron pad near the outer edge of the bottom of the buckle arm. The utility model locks the rail base through the buckle arm in cooperation with the stop block and the locking pin.
