[0040] See also Figures 1 to 5 As shown, the embodiment of the present application provides a ballpoint pen, comprising: a pen barrel 1, a nib inner shell 2, a nib outer shell 3 and a movable shell 4. The nib inner shell 2 is connected to one end of the pen barrel 1, and a receiving chamber is formed between the nib inner shell 2 and the pen barrel 1. The nib inner shell 2 is provided with a through port 2211 and a top column 2212, and the top column 2212 is located outside the receiving chamber. The nib outer shell 3 is connected to the nib inner shell 2, and a limiting chamber is formed between the nib outer shell 3 and the nib inner shell 2. The movable shell 4 is slidably connected to the nib outer shell 3, one end of the movable shell 4 is located in the limiting chamber, and the limiting chamber limits the range of movement of the movable shell 4, and the other end of the movable shell 4 extends out of the nib outer shell 3, and the movable shell 4 has a bead outlet chamber, and the bead outlet chamber is connected to the through port 2211, and one end of the movable shell 4 extending out of the nib outer shell 3 is provided with a bead outlet nozzle 41 connected to the bead outlet chamber. Under the action of external force, the movable shell 4 can move toward one side of the pen barrel 1, and the top column 2212 can push the bead body limited on the bead outlet mouth 41 out of the movable shell 4. The ballpoint pen of the present application does not need to use colloid adhesive when dotting beads. Only a light tap is needed, and the top column 2212 can push the bead body limited on the bead outlet mouth 41 out of the movable shell 4. The ballpoint pen of the present application is easy to operate and has high bead-dotting efficiency. The bead body is accommodated in the accommodating cavity, and there is no need to worry about the beads being scattered everywhere, which is very suitable for children to play.

[0041] like Figure 4 and Figure 5As shown, the movable shell 4 is provided with a plurality of cutout grooves 411, each of which extends to the bead outlet mouth 41 to separate the bead outlet mouth 41 to form a plurality of deformation pieces 412. The outer diameter of the bead body is slightly larger than the inner diameter of the bead outlet mouth 41. In the absence of external force, the bead body can be confined to the bead outlet mouth 41 and will not fall out. The movable shell 4 is a plastic part with a certain elastic deformation ability. Under the action of external force, the movable shell 4 moves toward one side of the pen holder 1, and the ejector column 2212 can push the bead body confined to the bead outlet mouth 41 out of the movable shell 4. During the process of the ejector column 2212 ejecting the bead, the bead pushes each of the deformation pieces 412, causing each of the deformation pieces 412 to move away from each other, thereby increasing the inner diameter of the bead outlet, and finally pushing the column out of the bead outlet. After the bead falls out, each of the deformation pieces 412 elastically recovers and moves closer to each other, so that the next bead is limited to the bead outlet mouth 41.

[0042] In one possible embodiment, Figure 2 , Figure 4 and Figure 5 As shown, the movable shell 4 is provided with a bead guide shell portion 42, and the bead guide shell portion 42 extends to the through port 2211, and the bead in the accommodating cavity can move to the bead outlet cavity along the bead guide shell portion 42. The bead guide shell portion 42 can guide the bead in the accommodating cavity to move to the bead outlet cavity.

[0043] like Figure 2 , Figure 4 and Figure 5 As shown, the bead guide shell 42 is an arc-shaped shell, and the cross section of the bead guide shell 42 is a "C" shape. The arc-shaped shell makes the space enclosed by the bead guide shell 42 larger, which is conducive to the passage of the beads.

[0044] like Figure 5 As shown, the movable shell 4 is provided with an inclined bottom wall 43 on the side away from the pen tip inner shell 2, and the bead outlet nozzle 41 is provided at the bottom end of the inclined bottom wall 43. The projection of the movable shell 4 along the length direction of the pen barrel 1 to the inclined bottom wall 43 is the highest end of the inclined bottom wall 43, and the bead outlet nozzle 41 is located at the bottom end of the inclined bottom wall 43. The inclined bottom wall 43 facilitates the column to roll freely to the bead outlet nozzle 41.

[0045] In one possible embodiment, Figure 2 , Figure 4 and Figure 5As shown, the movable shell 4 is provided with a flange edge 44 at one end away from the bead outlet nozzle 41, and the inner wall of the nib outer shell 3 is provided with an inner step 31. The flange edge 44 is located between the inner step 31 and the nib inner shell 2, and the nib inner shell 2 and the inner step 31 limit the range of movement of the movable shell 4. The nib inner shell 2 has a bottom wall 221, and the flange edge 44 is located between the inner step 31 and the bottom wall 221. The bottom wall 221 and the inner step 31 limit the range of movement of the movable shell 4.

[0046] like Figure 3 As shown, the top column 2212 includes a cylindrical shaft 2212a and a reinforcing strip 2212b, wherein the reinforcing strip 2212b extends along the cylindrical shaft 2212a and is connected to the cylindrical shaft 2212a. The reinforcing strip 2212b strengthens the structural strength of the top column 2212, making it less likely to break when the bead is pushed, and the reinforcing strip 2212b prolongs the service life of the top column 2212.

[0047] like Figure 3 As shown, the end of the cylindrical shaft 2212a extends out of the reinforcing strip 2212b. The reinforcing strip 2212b strengthens the structural strength without affecting the cooperation between the cylindrical shaft 2212a and the bead, so that the cylindrical shaft 2212a can push the bead out of the movable shell 4 under the action of external force.

[0048] In one possible embodiment, Figure 3 As shown, the pen tip inner shell 2 has a first barrel 21 and a second barrel 22, the first barrel 21 has a first internal thread 211, which is threadedly connected to the pen barrel 1, the second barrel 22 is connected to the first barrel 21, and the accommodating cavity is formed between the second barrel 22 and the pen barrel 1. The end of the pen barrel 1 close to the pen tip inner shell 2 has a second external thread 11, and the second external thread 11 is threadedly connected to the first internal thread 211. The second barrel 22 is provided with the through port 2211 and the top column 2212. The second barrel 22 has the bottom wall 221, the bottom wall 221 is provided with the through port 2211, and the top column 2212 is provided on the side of the bottom wall 221 away from the first barrel 21.

[0049] like Figure 2 and Figure 3 As shown, the second cylinder 22 has a first external thread 222, the nib shell 3 has a second internal thread 32, the nib shell 3 is threadedly connected to the second cylinder 22, and the second internal thread 32 is threadedly connected to the first external thread 222. The threaded connection makes the ballpoint pen of the present application easy to assemble.
