[0017] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] A steel binder clip, such as Figure 1As shown, it includes a clamp body 1, hard cardboard and two tail handles 3. Both sides of the clamp body 1 near the clamping opening are curled to form turns 4. The two tail handles 3 are rotatably connected to the two turns 4 respectively. The front of the clamp body 1 is provided with a groove 5 whose one end is connected to the side wall of the clamp body 1. A transparent plastic plate 2 is glued and connected to the groove 5. A cavity for accommodating the hard cardboard is formed between the plastic plate 2 and the groove 5. A sealing member for preventing the hard cardboard from escaping from the cavity is slidably connected to the front of the clamp body 1. After people use hard cardboard to mark the documents clamped by the long tail clip, the hard cardboard is stuffed into the cavity, and then the sliding sealing member covers the opening of the cavity. In the subsequent shaking process of the documents, the sealing member can better prevent the hard cardboard from escaping from the cavity. The transparent plastic plate 2 enables the plastic plate 2 to better keep the hard cardboard in the cavity while also allowing people to see the contents on the hard cardboard through the plastic plate 2.

[0019] like Figure 2 As shown, the closure member includes a blocking portion 6 and a curling portion 7 connected to the blocking portion 6 at one end. The curling portion 7 is a spirally rolled metal sheet made of a 50# first-grade steel strip through a bending process. One end of the curling portion 7 is fixedly connected to one end of the tail handle 3 located in the turning circle 4. When the movable end of the tail handle 3 is turned over to conflict with the clamp body 1, the curling portion 7 slides the blocking portion 6 to the opening of the cavity. The side of the clamp body 1 is curled to form a guide ring 8 that is perpendicular to the turning circle 4. A slide groove 9 is provided on the front side of the clamp body 1. The blocking portion 6 is slidably connected in the slide groove 9. When people use the long tail clip to clamp documents, they will fold the tail handle 3 onto the document by hand. During the folding process of the tail handle 3, the fixed end of the curling portion 7 will be driven to rotate together. At this time, the movable end of the curling portion 7 The end moves toward the tail handle 3 under the action of the curling part 7's own material, thereby driving the blocking part 6 to slide to the opening of the cavity, thereby covering the opening of the cavity and making it difficult for the hard cardboard in the cavity to escape from the opening of the cavity. The above-mentioned arrangement enables people to cover the opening of the cavity by folding the tail handle 3, making it more convenient to cover the opening of the cavity. In the process of people folding the tail handle 3, the rotating tail handle 3 drives the curling part 7 to rotate, and the curling part 7 drives the blocking part 6 to slide. In the process of the blocking part 6 sliding, the setting of the guide ring 8 can provide a better guiding effect for the sliding of the blocking part 6, and the opening of the slide groove 9 allows a part of the blocking part 6 to be exposed in the cavity, so that the hard cardboard can conflict with the blocking part 6 during the shaking process, so that the blocking part 6 can prevent the hard cardboard from escaping from the cavity.

[0020] like Figure 1 and Figure 2As shown, when the tail handle 3 conflicts with the front face of the clamp body 1, the blocking portion 6 is completely received in the guide ring 8. When people replace the documents in the clamp body 1, they need to replace the hard cardboard in the cavity. People fold the tail handle 3 onto the front face of the clamp body 1 by hand. At this time, the blocking portion 6 is completely received in the guide ring 8, and the shielding of the cavity opening by the blocking portion 6 disappears. People can take out the old hard cardboard through the opening, and then insert the newly replaced hard cardboard through the opening. The above arrangement enables people to remove the shielding of the cavity opening by the blocking portion 6 by folding the tail handle 3 onto the front face of the clamp body 1. The minimum force required for folding the tail handle 3 is greater than the maximum force for the curling portion 7 to curl. When people fold the tail handle 3 onto the document, the curling portion 7 curled on the tail handle 3 will not 3 rotates in the opposite direction, thereby ensuring that the blocking part 6 can better cover the opening of the cavity. The cross-section of the blocking part 6 is rectangular, and the four long sides of the blocking part 6 are in conflict with the inner circumferential wall of the guide ring 8. During the sliding process of the blocking part 6, the blocking part 6 is always in contact with the inner wall of the slide groove 9 and the inner wall of the guide ring 8, so that the blocking part 6 is not easy to shake during the sliding process, and the subsequent blocking effect of the blocking part 6 on the cavity opening is better guaranteed. The thickness of the hard cardboard is less than the thickness of the cavity. During the process of people replacing the hard cardboard, the hard cardboard can be poured out of the cavity by tilting the clamping body 1, so that people do not need to buckle the hard cardboard out of the cavity with their fingers, making it more convenient to take out the hard cardboard. The clamping body 1 is made of stainless steel, which better extends the service life of the clamping body 1.
