[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0025] Embodiment 1: A touch pen facilitating replacement of a contact, as Figures 1-4 shown, includes a pen shell 1, and a pen core 4 installed inside the pen shell 1. A placement ring 5 is installed at the lower end of the pen core 4. The placement ring 5 is composed of four deformable arc-shaped structures. The half part of the placement ring 5 close to the pen core 4 is in the shape of a horizontal cylinder, and the other part of the placement ring 5 is in the shape of a frustum. The lower end specification of the placement ring 5 is larger than the specification at the connection between the placement ring 5 and the pen core 4. The outer side of the placement ring 5 is threadedly engaged with a fastening ring 6. A contact 7 is inserted into the middle of the placement ring 5, and anti-slip lines are provided on the inner wall of the placement ring 5. A limiting cone 3 is inserted into the pen core 4 and the placement ring 5. The limiting cone 3 is used for limiting the pen core 4, and a rotating shell 2 is installed on the outer side of the limiting cone 3. The rotating shell 2 is rotationally fastened to the pen shell 1. The contact 7 is inserted into the rotating shell 2 and extends to the outside thereof.

[0026] When the contact 7 needs to be replaced, first rotate the rotating shell 2 to move it and the limiting cone 3 out of the interior of the pen shell 1. Then rotate the fastening ring 6 to move it inward into the device, releasing the squeezing and fastening effect on the placement ring 5. Finally, remove the internal contact 7, insert a new contact 7 into the interior of the placement ring 5, then rotate the fastening ring 6 in the reverse direction to fasten the position of the contact 7. Finally, fasten the rotating shell 2 inside the pen shell 1 to complete the replacement of the contact 7. And based on the conical structure of the placement ring 5, when the fastening ring 6 rotates outward, it gradually fastens the placement ring 5. Correspondingly, the anti-slip lines on the inner wall of the placement ring 5 can ensure the stability of the position of the contact 7 during installation and use, thus facilitating the replacement of the contact 7 while ensuring the fastening and stability of its installation position.

[0027] As Figures 1-4 shown, the limiting cone 3 is overall conical, and the conical direction of the limiting cone 3 is opposite to the conical direction of the pen core 4.

[0028] A support groove is provided on the inner wall of one end of the pen shell 1 close to the rotating shell 2, and a support ring is installed at one end of the rotating shell 2 close to the pen shell 1. The support ring is rotationally fastened to the support groove.

[0029] When fastening the rotating shell 2 by rotation, based on the connection between the support ring and the support groove, the two ends of the rotating shell 2 and the pen shell 1 are in horizontal contact, ensuring that when they are fastened in contact, the outer sides of the rotating shell 2 and the pen shell 1 are in a smooth state, ensuring the comfort of holding when the device is connected and used. And under the reverse limiting of the limiting cone 3, when it contacts the pen core 4, it provides limiting support for the pen core 4.

[0030] As Figures 1-4 shown, the inner wall specification of the fastening ring 6 is slightly larger than the outer specification of the vertical part of the placement ring 5. The fastening ring 6 is used to adjust the tightness of the placement ring 5.

[0031] When the fastening ring 6 continues to rotate, when it gradually contacts the outer conical part of the placement ring 5, limited by the inner wall specification of the fastening ring 6, the placement ring 5 deforms towards the middle, forming an effect of limiting the contact 7. And under the effect of the gradually increasing conical surface of the placement ring 5, continuously rotating the fastening ring 6 can reduce and adjust the limiting space in the middle of the placement ring 5, enabling it to limit contacts 7 of various specifications.

[0032] Embodiment 2: A touch pen facilitating the replacement of the contact, as Figures 1-4 shown, a limiting disc 8 is provided above the pen core 4. A connecting column 10 is installed at the upper end of the limiting disc 8, and a fastening bolt 11 is installed on the upper surface of the connecting column 10.

[0033] The fastening bolt 11 is in threaded engagement with a rotating head 12. The fastening bolt 11 extends into the interior of the rotating head 12. A rotating ring 13 is installed at the lower end of the rotating head 12, and the rotating ring 13 is rotatably installed at the upper end of the pen shell 1.

[0034] The limit disk 8 and the connecting column 10 are both located in the upper half inside the pen case 1. At least two guide rods 9 are installed on the outer side of the limit disk 8. The two guide rods 9 are in opposite positions. The guide rods 9 are slidably connected to the guide grooves 14, and the guide grooves 14 are opened in the upper half of the inner wall of the pen case 1.

[0035] Rotate the rotating head 12. Based on the limitation of the connecting column 10 by the guide rod 9, the fastening bolt 11 is synchronously limited. Thus, when the rotating head 12 is rotated, under the action of the internal thread thereof, the fastening bolt 11 moves vertically, driving the connecting column 10 and the limit disk 8 to move in height, and the distance between the refill 4 and the limit disk 8 can be adjusted, so that the inside of the device can be adjusted and used according to refills 4 of different lengths, improving the diversity during the use of the device.

[0036] Working principle: When the contact 7 needs to be replaced, first rotate the rotating shell 2 to move it and the limit cone 3 out of the inside of the pen case 1. Then rotate the fastening ring 6 to move it towards the inside of the device, releasing the effect of squeezing and fastening the placement ring 5. Finally, take out the internal contact 7, insert a new contact 7 into the inside of the placement ring 5, then rotate the fastening ring 6 in the reverse direction to fasten the position of the contact 7, and finally fasten the rotating shell 2 inside the pen case 1 to complete the replacement of the contact 7. Rotate the rotating head 12. Based on the limitation of the connecting column 10 by the guide rod 9, the fastening bolt 11 is synchronously limited. Thus, when the rotating head 12 is rotated, under the action of the internal thread thereof, the fastening bolt 11 moves vertically, driving the connecting column 10 and the limit disk 8 to move in height, and the distance between the refill 4 and the limit disk 8 can be adjusted, so that the inside of the device can be adjusted and used according to refills 4 of different lengths.

[0037] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
