[0023] The utility model will be further explained in connection with the drawings. These drawings are all simplified schematic diagrams, just with the schematic mode to illustrate the basic structure of the utility model, so it just shows the constitution related with the utility model.

[0024] Example 1

[0025] As shown in Figures 1-3, the mushroom-shaped buckle is a disc-shaped structure formed by a metal disc body 1. The outer edge of the disc body 1 has a ring-shaped buckle 2, which protrudes to both sides, giving the mushroom-shaped cross-section. The disc body 1 and the buckle 2 are an integral structure. The disc body 1 has a first folded edge 21, an arc-shaped folded edge 22, and a second folded edge 23 arranged sequentially around its perimeter. The first folded edge 21 and the second folded edge 23 are located on the same arc surface and perpendicular to the plane of the disc body 1. The first folded edge 21, the arc-shaped folded edge 22, and the second folded edge 23 form the buckle 2. The first folded edge 21, the arc-shaped folded edge 22, and the second folded edge 23 are integral structures formed by continuous metal stamping using a metal die.

[0026] In this embodiment, metal materials are used, giving it a metal texture. The surface of the mushroom buckle is electroplated, which improves the feel when using it.

[0027] In one embodiment, the center of the disc body 1 is provided with a hollowed-out portion, which can be designed as a hollowed-out hole of any shape.

[0028] Example 2

[0029] like Figure 4 , 5 As shown, this utility model also provides a loose-leaf notebook, including multiple sheets of paper 4 and multiple mushroom-shaped clips as described in Embodiment 1. The mushroom-shaped clips bind the sheets of paper 4 into a book. The side edge of each sheet of paper 4 is provided with a mushroom-shaped hole 41 that matches the mushroom clip. The tail of the mushroom-shaped hole 41 extends towards the edge of the sheet of paper 4, forming an open groove structure. The sheets of paper 4 are easy to place, remove, and replace.

[0030] Example 3

[0031] See Figures 6-8 The difference between this embodiment and Embodiment 1 is that the mushroom buckle has a notch 24, and a locking arc sleeve 3 is sleeved on the outer edge of the buckle ring 2. The locking arc sleeve 3 can slide on the buckle ring 2, and the arc length of the locking arc sleeve 3 is greater than that of the notch 24. At the position where the locking arc sleeve 3 closes the notch 24, a positioning point (not shown in the figure) is provided between the locking arc sleeve 3 and the notch 24.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
