[0028] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a magnetic long tail clip, including a first clamping plate 1, the top of the first clamping plate 1 is fixedly equipped with an elastic plate 2, the end of the elastic plate 2 is fixedly equipped with a second clamping plate 3, the outer walls of the first clamping plate 1 and the second clamping plate 3 are both fixedly equipped with a positioning shell 4, the inner wall of the positioning shell 4 is provided with a positioning column 5, the middle of the positioning column 5 is provided with a mounting groove 7, the inner wall of the mounting groove 7 is sleeved with a strong spring 8, the outer wall of the strong spring 8 is abutted with a bayonet pin 9, the end of the bayonet pin 9 is abutted with a button 6, the middle of the positioning shell 4 is provided with a movable groove 10, and the outer wall of the button 6 is fixedly sleeved with a limiting ring 11. By providing the first clamping plate 1, elastic plate 2, second clamping plate 3, positioning shell 4, and positioning column 5 structure, during the use of the binder clip, the user can adjust the clamping force between the first clamping plate 1 and the elastic plate 2 by replacing the positioning column 5 with different magnetic forces, thereby facilitating the user to clamp papers of different thicknesses, reducing damage to the surface of the paper while ensuring the clamping force, thereby improving the practicality and application range of the binder clip.

[0029] like Figure 3 and Figure 4 As shown, the pin 9 is located at one end of the inner wall of the installation groove 7 and is fixedly assembled with a limit ring, and the outer wall of the limit ring is slidably connected to the inner wall of the installation groove 7. Through the set limit ring and the installation groove 7 structure, when the user inserts the positioning column 5 into the positioning shell 4, the elasticity of the strong spring 8 can be used to push the limit ring and the pin 9 to move together, so that the pin 9 can be plugged into the round hole, thereby achieving the effect of quickly fixing the positioning column 5, thereby improving the user's disassembly and assembly efficiency of the positioning column 5.

[0030] like Figure 4As shown, the inner walls of the mounting groove 7 and the movable groove 10 are both provided with circular holes, and the diameter of the circular holes is adapted to the diameter of the bayonet 9. Through the provided circular hole structure, the positioning column 5 can be quickly fixedly connected to the positioning shell 4 with the cooperation of the mounting groove 7, the strong spring 8 and the bayonet 9. When the positioning column 5 needs to be removed, the user can press the button 6 to disengage the bayonet 9 from the circular hole, thereby achieving the effect of quickly removing the positioning column 5, facilitating the user's operation, and further improving the practicality of the binder clip.

[0031] like Figure 3 and Figure 4 As shown, the outer wall of the limiting ring 11 is slidably connected to the inner wall of the movable groove 10, and the positioning column 5 is fixedly connected to the positioning shell 4 through the bayonet 9. Through the structure of the movable groove 10, the limiting ring 11, the positioning column 5, the positioning shell 4, and the bayonet 9, when the positioning column 5 is fixed in the positioning shell 4 under the action of the bayonet 9, the oppositely attracted characteristics of the permanent magnets on the first clamping plate 1 and the elastic plate 2 are utilized to ensure the clamping force of the binder clip on the paper, and the bayonet 9 and the movable groove 10 can facilitate the user to press the button 6 to replace the positioning column 5, so that the user can adjust the magnetic force of the permanent magnet, reduce the damage caused to the paper by the binder clip during the clamping process, and thus improve the practicality of the binder clip.

[0032] like Figure 1 and Figure 2 As shown, there are four positioning posts 5, which are divided into two groups. The two groups of positioning posts 5 are respectively arranged on both sides of the first clamping plate 1 and the elastic plate 2. By setting the two groups of positioning posts 5 structure, when the first clamping plate 1 and the elastic plate 2 are both attached to the paper, two groups of permanent magnets are used to ensure the clamping force of the first clamping plate 1 and the elastic plate 2 on the paper, so as to prevent the paper from escaping from the binder clip due to excessive thickness or insufficient elastic force provided by the elastic plate 2, thereby ensuring the clamping effect of the binder clip on the paper, and further improving the stability of the binder clip in the process of clamping the paper.

[0033] like Figure 1 and Figure 2 As shown, a through groove is formed on the outer wall of the positioning shell 4, and a permanent magnet is fixedly mounted on the outer wall of the positioning column 5, and the diameter of the permanent magnet is adapted to the diameter of the through groove. The permanent magnets on the first clamping plate 1 and the elastic plate 2 attract each other with opposite sexes. Through the set structure of the permanent magnet and the positioning column 5, after the user installs the positioning column 5 in the positioning shell 4, the permanent magnet can be used to ensure the tightness of the fit between the first clamping plate 1 and the elastic plate 2, thereby ensuring the clamping effect of the binder clip on the paper, and the user can also quickly replace the positioning column 5 so that the user can adjust the magnetic strength of the permanent magnet, thereby facilitating the user to clamp papers of different thicknesses, thereby increasing the use range of the binder clip.

[0034] The technical solution provided by the utility model is that when clamping thinner paper, the round rod can be directly pressed, and at this time the suction force between the permanent magnets is less than the pressure, so that the angle between the first clamping plate 1 and the elastic plate 2 becomes larger, and then the user can directly send the edge of the paper to the gap between the first clamping plate 1 and the elastic plate 2, and then release the round rod, so that the first clamping plate 1 and the elastic plate 2 are brought close again to clamp the paper. When it is necessary to clamp thicker paper, the button 6 can be pressed, so that the button 6 and the limit ring 11 both slide along the inner wall of the movable groove 10 to push the latch 9 to move toward the strong spring 8. At this time, the strong spring 8 is compressed to make the latch 9 disengage from the round hole. The user can pull out the positioning column 5, replace it with a permanent magnet with greater magnetic force, and reinstall the new positioning column 5 in the positioning shell 4 through the above reverse steps, and finally the thicker paper can be clamped.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
