[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Example 1: Combination Figures 1-4 As shown, an adjustment mechanism for adjusting the elasticity of a fountain pen tip of the present invention includes a fountain pen body 1, a nib 3 and a feed 2 provided on the fountain pen body 1. A plurality of feed extensions 4 are provided at one end of the feed 2 close to the nib 3 for ink discharge, one of the feed extensions 4 being provided with a limiting fixing member. The limiting fixing member is used to mount the feed extension 4 to the end of the feed 2, so that the pressure between the nib 3 and the feed 2 can be adjusted to change the elasticity of the nib 3.

[0044] By providing the feed extension 4 and the limiting fixing part, the length of the feed 2 can be adjusted according to one's own writing habits during the writing process. When the feed 2 is shortened, the feed 2 reduces the elastic deformation of the pen tip 3 upward. According to Hooke's law, the pressure between the pen tip 3 and the feed 2 will be correspondingly reduced, and the pen tip 3 will be easier to bounce up. Conversely, when the feed 2 is thickened, the feed 2 increases the elastic deformation of the pen tip upward. According to Hooke's law, the pressure between the pen tip 3 and the feed 2 will be correspondingly increased, and the pen tip 3 will not be easy to bounce up. The feed extension 4 and the feed 2 are made of the same material, both of which can be made of nickel-plated steel sheets.

[0045] In a preferred embodiment, the present invention can be further configured as follows: Figure 2 、 Figure 3As shown in the figure; the side surface of the tongue extension 4 close to the end of the tongue 2 is the contact surface, and the side surface of the tongue extension 4 away from the tongue 2 is the mounting surface, wherein the contact surface of the tongue extension 4 is processed with a first limiting groove 6, and the mounting surface of the tongue extension 4 is processed with not less than two second limiting grooves 7, the cross-sectional shape of the first limiting groove 6 and the second limiting groove 7 is circular, square or oval, the mounting surface of the tongue extension 4 is fixedly installed with a first limiting block 8 matched with the first limiting groove 6, and the contact surface of the tongue extension 4 is fixedly installed with a second limiting block 9 matched with the second limiting groove 7, through the setting of the first limiting groove 6, the second limiting groove 7, the first limiting block 8 and the second limiting block 9, when the adjacent two tongue extensions 4 are connected, the first limiting block 8 can be placed on the inner side of the first limiting groove 6, and the second limiting block 9 can be placed on the inner side of the second limiting groove 7, so that the longitudinal position of the adjacent two tongue extensions 4 is limited, and the misalignment of the tongue extension 4 during assembly and installation is avoided, and the uniformity of the tongue extension during installation is further improved.

[0046] In a preferred embodiment of the present application, the pen tongue extension can be further configured as shown in Figure 1 、 Figure 2 The edge corner of the tongue extension 4 is smoothly transitioned, wherein the side surface of the tongue extension 4 close to the tongue 2 gradually increases, and the tongue extension 4 is further limited, so that it can be matched with the shape of the pen tongue 2 during assembly.

[0047] In a preferred embodiment of the present application, the pen tongue extension can be further configured as shown in Figure 3 、 Figure 4 The limiting fixing part is a fastener fixing assembly 5, and the fastener fixing assembly 5 comprises:

[0048] The first threaded hole 51 is arranged at the center of the surface of the tongue extension 4;

[0049] The second threaded hole 52 is arranged on the side surface of the tongue 2 close to the tongue extension 4, and the center of the first threaded hole 51 is located on the same straight line;

[0050] The first base plate 53 is arranged on the contact surface of the tongue extension 4; and

[0051] The fastening screw 54 is arranged on the first base plate 53 and connected with the first threaded hole 51 and the second threaded hole 52, and the tongue extension 4 is fixed on the end of the tongue 2 through the fastening screw 54. When the tongue extension 4 is assembled, the fastening screw 54 can be passed through the first base plate 53, and then connected with the first threaded hole 51 and the second threaded hole 52, so that the tongue extension 4 can be connected to the end of the tongue 2. The whole connection process is simple and convenient, and the user can disassemble and assemble conveniently, so as to adjust the elastic force of the pen point 3 to the user's own needs.

[0052] The specific working principle of the adjusting mechanism for adjusting the elasticity of the pen point is as follows:

[0053] Firstly, a certain number of tongue extensions 4 are taken, the first limiting block 8 on one of the tongue extensions 4 is connected into the first limiting groove 6 on another tongue extension 4, and the second limiting block 9 is connected with the second limiting groove 7, so that the adjacent two tongue extensions 4 can be clamped together, and the phenomenon of mutual misalignment of the adjacent two tongue extensions 4 is avoided.

[0054] Then, the fastening screw 54 is passed through the first base plate 53, and then connected with the first threaded hole 51 and the second threaded hole 52, so that a certain number of tongue extensions 4 can be installed on the end of the tongue 2.

[0055] Finally, the pen is used for writing to test the elasticity of the pen point 3, and then the number of the tongue extensions 4 is adjusted according to the writing habit of the user, so that the elasticity can meet the expected elasticity. Meanwhile, the pen point 3 can be permanently deformed away from the tongue 2, so that the elastic deformation of the pen point 3 upward is reduced after installation. According to Hooke's law, the pressure between the pen point 3 and the tongue 2 will be reduced accordingly, and the pen point 3 will be more elastic. Conversely, the pen point 3 is permanently deformed towards the tongue 2, so that the elastic deformation of the pen point 3 upward is increased after installation. According to Hooke's law, the pressure between the pen point 3 and the tongue 2 will be increased accordingly, and the pen point will be less elastic.

[0056] Embodiment two, in combination Figures 5-6 with embodiment one, the difference is that the limiting and fixing part is a magnetic fixing assembly 10, and the magnetic fixing assembly 10 comprises:

[0057] The first circular hole 101 is arranged at the center of the surface of the tongue extension 4;

[0058] The second circular hole 102 is arranged on the surface of the tongue 2 close to the tongue extension 4, and the center of the first circular hole 101 is located on the same straight line.

[0059] A circular magnet 103 is arranged in the second circular hole 102.

[0060] A second base plate 104 is arranged on the contact surface of the tongue extension 4.

[0061] A T-shaped rod 105 is arranged on the second base plate 104 and inside the first circular hole 101 and the second circular hole 102, and is connected with the circular magnet 103. The T-shaped rod 105 is fixed on the end of the tongue 2 by the tongue extension 4. An extraction groove 11 is formed on the end of the T-shaped rod 105 away from the circular magnet 103. A stopper 12 is welded on the inner side of the extraction groove 11. When the tongue extension 4 is assembled, the T-shaped rod 105 is first passed through the second base plate 104, then through the first circular hole 101, and finally placed in the second circular hole 102. The tongue extension 4 is installed on the end of the tongue 2 by the mutual attraction between the circular magnet 103 and the T-shaped rod 105. The entire installation process does not require the use of auxiliary tools, making it convenient for users to operate. When the number of tongue extensions 4 is increased or decreased, a tool with a hook is used to be placed in the extraction groove 11 and then hooked on the stopper 12, and the T-shaped rod 105 is pulled away from the tongue 2, so that the T-shaped rod 105 can be taken out of the second circular hole 102.

[0063] Step one: a number of tongue extensions 4 are placed on the surface of the tongue 2.

[0064] Step two: one of the tongue extensions 4 is clamped in the first limiting groove 6 on another tongue extension 4, and the second limiting block 9 is clamped in the second limiting groove 7, to ensure that the relative displacement between the two adjacent tongue extensions 4 does not occur.

[0065] Step three: the limiting fixing member is used to fix the number of tongue extensions 4 on the end of the tongue 2.

[0066] Step four: the pen is used for writing, and then the number of tongue extensions 4 is adjusted according to the elasticity of the tongue 2. The operations of steps one to three are repeated when the number of tongue extensions 4 is increased or decreased.
