Description

Technical Field

[0001] The utility model relates to the technical field of capacitive pens, in particular to an active capacitive pen which is convenient for replacing the pen head. Background Art

[0002] A capacitive pen is a device that uses conductive materials to mimic a finger touch screen. It is divided into two types: passive and active. This article introduces the principles, classifications, advantages and disadvantages of capacitive pens, recommended products on the market, and the differences between capacitive pens and inductive pens and styluses.

[0003] For example, the patent with announcement number CN216792858U discloses a detachable and replaceable nib capacitive pen including a pen body, a refill holder, a pen head and a pen tip. An internal thread is provided at one end of the pen body, the refill holder is installed in the pen body, and a fixing part is provided at the end of the refill holder away from the pen body. A sleeve that can be sleeved on the refill holder is provided in the pen head, and an external thread that cooperates with the internal thread is also provided on the pen head for fixing the pen head to the pen body. A slot hole connected to the sleeve is provided on the pen head, and a rod-shaped conductive part is provided on the pen tip. The rod-shaped conductive part can be inserted into the slot hole to be placed in the sleeve and connected to the fixing part of the refill holder.

[0004] Through the above configuration, the prior art capacitive pen with a detachable and replaceable pen tip can realize quick replacement of the pen tip. However, the prior art capacitive pen with a detachable and replaceable pen tip including the pen holder has the following defects during operation:

[0005] In the above technical scheme, when the pen tip is replaced, the pen tip is rotated in the opposite direction so that the two cards of the refill holder are separated from the sleeve. During the period when the two cards are separated from the sleeve, the two cards will move away from each other as the diameter of the sleeve increases, and the rod-shaped conductive part loses the clamping force of the two cards, and then the pen tip can be separated from the pen tip to complete the disassembly of the pen tip. When the pen tip needs to be installed, the fixing part of the refill holder is placed in the sleeve of the pen tip, and the pen tip is connected to the pen shaft through a thread. During this process, the two cards will not approach each other, which leads to a technical problem that the fixing work of the pen tip is not stable enough. Utility Model Content

[0006] The utility model aims to provide an active capacitive pen with an easy-to-replace pen tip, and is mainly used to solve the technical problems in the prior art of cumbersome pen tip removal and unstable pen tip fixing.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] An active capacitive pen that is easy to replace the pen tip comprises a pen holder and a pen tip, wherein the end of the pen tip is fixedly connected to a connecting ring, the outer side wall of the connecting ring is provided with an external thread, the inner side wall of the pen tip is detachably connected to a rod-shaped conductive part, the end of the rod-shaped conductive part is fixedly connected to a pen tip, the inner side wall of the pen holder is fixedly connected to a refill holder, the end of the refill holder is symmetrically fixedly connected to a card, the inner side wall of the pen holder is provided with an internal thread, the outer side wall of the card is fixedly connected to a clamping assembly, the outer side wall of the pen holder is symmetrically penetrated with a slide groove, and the inner side wall of the slide groove is slidably connected to an adjustment assembly.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: The active capacitive pen structure for easy replacement of the pen tip in the utility model is similar to the existing detachable and replaceable pen tip capacitive pen including a pen body structure. For example, the patent with publication number CN216792858U discloses a detachable and replaceable pen tip capacitive pen including a pen body. The main improvement of the utility model is that when the pen tip needs to be replaced, the adjustment component is slid upward so that the adjustment component slides upward on the inner wall of the slide slot. During this process, the clamping component works so that the clamping components move away from each other, and the distance between the two cards will become larger and larger. The staff can pull the rod-shaped conductive part outward to move the rod-shaped conductive part outward along the inner wall of the pen tip, so that the rod-shaped conductive part can be quickly taken out, thereby facilitating replacement. When the new rod-shaped conductive part is inserted between the cards, the clamping components are brought closer to each other by sliding the adjustment component in the opposite direction, thereby reducing the distance between the two cards, and the rod-shaped conductive part is clamped by the card to complete the replacement of the pen tip.

[0011] 2. Beneficial effects:

[0012] The prior art solves the technical problem of quickly replacing the pen tip by providing a capacitive pen with a detachable and replaceable pen tip. However, the prior art has the technical problems that the removal of the pen tip is cumbersome and the fixing work of the pen tip is not stable enough. The present solution provides an adjustment component, which can quickly drive the clamping component to work. When the pen tip needs to be replaced, there is no need to disassemble the pen tip. The clamping component allows two cards to quickly clamp the rod-shaped conductive part, thereby solving the technical problem of convenient replacement.

[0013] Preferably: the clamping assembly includes an extrusion block fixedly connected to the outer side wall of the card, the side wall of the extrusion block is fixedly connected to a connecting rod, and the end of the connecting rod away from the extrusion block is rotatably connected to a connecting rod. When the rod-shaped conductive part needs to be disassembled, the connecting rod is pulled upward. During this process, the connecting rod and the connecting rod rotate, and the inclination angle of the connecting rod gradually increases, so that the two extrusion blocks no longer squeeze the card, and the distance between the two cards will become larger and larger. The staff can pull the rod-shaped conductive part outward to move the rod-shaped conductive part outward along the inner side wall of the pen head, and the rod-shaped conductive part can be quickly taken out, thereby facilitating the replacement of the pen tip.

[0014] Preferably, the extrusion block is arc-shaped and is in close contact with the outer side wall of the card, so that the rod-shaped conductive part can be clamped by the extrusion block abutting against the card.

[0015] Preferably: the adjustment assembly includes a slider slidably connected to the inner wall of the slide groove, the opposite sides of the two sliders are fixedly connected with a mounting seat, the inner wall of the mounting seat is rotatably connected to the other end of the connecting rod, the outer wall of the slider is fixedly connected with a sliding ring, and the sliding ring is slidably connected to the outer wall of the pen barrel. When the connecting rod needs to be pulled upward, the sliding ring is pushed upward to make the sliding ring slide upward along the outer wall of the pen barrel. In this process, the slider slides upward along the inner wall of the slide groove, and the connecting rod is driven upward by the mounting seat, thereby achieving the purpose of convenience.

[0016] Preferably: a spring is fixedly connected to the top of the slider, and the other end of the spring is fixedly connected to the side wall of the slide groove. When the slider moves upward along the inner wall of the slide groove, the spring is compressed. When a new rod-shaped conductive part is placed between the two cards, the sliding ring is released, and the slider automatically moves downward under the action of the compression spring, thereby re-contacting the card through the two extrusion blocks, reducing the distance between the two cards, and achieving the clamping of the new rod-shaped conductive part.

[0017] Preferably, when the slider is at the uppermost end, the spring is in a compressed state, and the expansion force of the spring prevents the sliding ring from automatically moving upward, thereby ensuring the stability of the card relative to the rod-shaped conductive part.

[0018] Preferably, the extrusion block is located at the upper end of the internal thread to prevent the extrusion block from affecting the connection between the external thread and the internal thread. BRIEF DESCRIPTION OF THE DRAWINGS

The side wall of the extrusion block 14 is fixedly connected with a connecting rod 17. The end of the connecting rod 17 away from the extrusion block 14 is rotatably connected with the connecting rod 9. During the rising process of the connecting rod 9, the connecting rod 9 and the connecting rod 17 rotate, and the inclination angle of the connecting rod 17 gradually increases, so that the two extrusion blocks 14 no longer squeeze the card 15, and the distance between the two cards 15 will become larger and larger.
