Referring to fig. 1, a split type buckle is shown, which includes a buckle body 10, an opening/closing handle 20 and an elastic element 30, wherein the buckle body 10 includes a buckle hook portion 11, an end cover portion 12 and a connecting portion 13, wherein the buckle hook portion 11 and the end cover portion 12 both include two half bodies, and the two half bodies of the buckle hook portion 11 and the end cover portion 12 are mirror-structured with a central line of the middle connecting portion 13 as a symmetrical line; the reason why the hook part 11 and the end cap part 12 have mirror symmetry is to fold them in two and then laser-weld them together to form an integral shape with no surface seam.

The opposite surface of the end cover part 12 is provided with a recessed hole 121, the convex column 23 on the opening-closing handle 20 is correspondingly clamped in the recessed hole 121, and the elastic element 30 is elastically propped against the periphery of the convex column 23 and the joint part of the buckling part 11 and the end cover part 12.

Before the buckle body structure is folded in half, the opening and closing handle 20 is placed in a corresponding position in the buckle body, and the convex column 23 of the opening and closing handle 20 can be well buckled because the concave hole 121 in the end cover part 12 can form a closed buckling space after the buckle body is welded. The opening and closing handle is hinged and fixed in the buckle body in a hinging way by the groove.

The connecting portion 13 is made of a flexible metal material and can be bent.

Referring to fig. 3, when the connecting portion 13 is bent, the two halves of the end cover portion 12 and the two halves of the fastening portion 11 are respectively abutted, a recess is formed at the joint of the fastening portion 11 and the end cover portion 12, and the recessed hole on the opposite surface of the end cover portion forms a recessed groove to define the convex column 23 of the opening and closing handle 20. The shackle is now laser welded along the path of curve a in figure 3 to form a seam free welded product.

The opening and closing handle 20 is Y-shaped, the first branch end 21 extends to the outside of the buckle body through the space of the joint of the buckle hook part 11 and the end cover part 12, and the second branch end 22 is in butt joint with the circular arc space of the buckle hook part 11 to form a closed ring with the buckle hook part 11.

The elastic element 30 is a torsion spring, and the torsion spring includes a coil 31 and two elastic arms opened according to a certain branching angle, and is divided into a first elastic arm 32 and a second elastic arm 33. The torsion spring is made of K gold metal.

An arc half-groove 24 is arranged around the convex column 23 of the opening-closing handle 20, and a first elastic arm 32 of the elastic element is propped against the arc half-groove 24.

A pressing groove 14 is further formed in the joint of the buckling part 11 and the end cover part 12 in the direction towards the buckling part, and the second elastic arm 32 of the elastic element is oppositely pressed against the pressing groove 14.

The coil 31 is inserted into the boss 23 of the handle 20 and the recessed hole 121 on the inner surface of the cap 12.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention is disclosed in the preferred embodiment, it is not limited to the above description, and any person skilled in the art can make modifications or changes equivalent to the above disclosed technical content without departing from the technical scope of the present invention.
