[0020] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] See also Figure 1As shown, a binder clip comprises a first bottom plate 1 and a second bottom plate 2 which are symmetrically arranged, side plates 3 for clamping documents are integrally formed on the first bottom plate 1 and the second bottom plate 2, a tail handle 4 is rotatably connected to the side plate 3, the tail handle 4 is made of stainless steel material, the stainless steel material has high strength and corrosion resistance, so that the tail handle 4 has a long service life, an adjustment mechanism for adjusting the distance between the first bottom plate 1 and the second bottom plate 2 is arranged between the first bottom plate 1 and the second bottom plate 2, by controlling the adjustment mechanism to adjust the distance between the first bottom plate 1 and the second bottom plate 2, the distance between the first bottom plate 1 and the second bottom plate 2 can be controlled, thereby driving the mutual distance between the two side plates 3 and the approach, and the size of the clamping space between the two side plates 3 can be adjusted, and when the binder clip clamps documents, the distance between the two side plates 3 can be adjusted accordingly according to the size of the documents to be clamped, so that the binder clip is suitable for documents of different thicknesses and has a better clamping effect.
[0022] See also Figure 1-3 As shown, a slide rail 5 is arranged on the outer side wall of the first bottom plate 1, and a slider 6 slidably connected to the slide rail 5 is arranged on the outer side wall of the second bottom plate 2. In the process of adjusting the distance between the first bottom plate 1 and the second bottom plate 2, the slider 6 slides in the slide rail 5, and the slide rail 5 guides the sliding of the slider 6, so that the sliding of the slider 6 in the slide rail 5 is relatively smooth, thereby making the operation of adjusting the distance between the first bottom plate 1 and the second bottom plate 2 relatively smooth. The adjustment mechanism includes a screw rod 7 rotatably connected to the slide rail 5 and a driving member for driving the screw rod 7 to rotate, and the slider 6 is threadedly connected to the screw rod 7. In the process of adjusting the distance between the first bottom plate 1 and the second bottom plate 2, the screw 7 is driven to rotate in the slide rail 5 by controlling the driving member. Since the slider 6 is slidably connected to the slide rail 5, the slider 6 is limited by the slide rail 5 and only moves in the slide rail 5. The sliding block 6 is threadedly connected to the screw rod 7, so when the screw rod 7 rotates, the sliding block 6 will slide freely in the slide rail 5 as the screw rod 7 rotates, and the operation is relatively convenient, making it relatively convenient to adjust the distance between the first base plate 1 and the second base plate 2. The driving member includes a rotating wheel 8 coaxially arranged on the screw rod 7, and a through groove 9 for the rotating wheel 8 to pass through is provided on the bottom wall of the slide rail 5. By turning the rotating wheel 8 outside the slide rail 5, the rotation of the screw rod 7 in the slide rail 5 is driven. The rotating wheel 8 is more easily applied as a fulcrum, making it relatively convenient to drive the screw rod 7 to rotate. An anti-skid rubber ring 12 is sleeved on the outer peripheral wall of the rotating wheel 8. The anti-skid rubber ring 12 increases the friction coefficient of the surface of the rotating wheel 8. In the process of turning the rotating wheel 8 by hand, slipping is not easy to occur, thereby making it relatively easy to turn the rotating wheel 8 to drive the screw rod 7 to rotate.
[0023] See also Figure 4As shown in the figure, a blocking piece 10 is arranged on the side of the first bottom plate 1 away from the slide rail 5. In the process of clamping the document, the blocking piece 10 contacts the side of the document, so that the contact surface between the document and the blocking piece 10 is relatively flat, and the document is prevented from slipping during the clamping process, so that the clamped document is relatively neat as a whole. A limiting piece 11 is arranged on the second bottom plate 2, and a space for accommodating the blocking piece 10 is formed between the limiting piece 11 and the second bottom plate 2. After the first bottom plate 1 and the second bottom plate 2 are away from each other, the blocking piece 10 is in contact with the limiting piece 11 and the second bottom plate 2. The bottom plates 2 slide in the direction away from the second bottom plate 2. Since the blocking piece 10 is between the limiting piece 11 and the second bottom plate 2, its two sides are respectively limited by the limiting piece 11 and the second bottom plate 2. When the tail handle 4 is pressed to drive the side plate 3 to open, the two sides of the blocking piece 10 respectively contact with the limiting piece 11 and the surface of the second bottom plate 2. Since the limiting piece 11 and the blocking piece 10 are respectively arranged on the second bottom plate 2 and the first bottom plate 1, the blocking piece 10 and the limiting piece 11 effectively share the pressure on both sides of the slide rail 5, thereby improving the overall strength of the binder clip.
