Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stationery, specifically relating to a pen. Background Technology
[0002] A lead-out pen is a writing instrument with a unique lead-out mechanism. When not in use, the writing part of the lead is placed inside the pen barrel to protect the lead. For example, by pressing the button or device at the end of the pen, the lead is pushed forward. This not only enables the lead-out function but also helps to calm the user's emotions and promote finger movement. However, the existing pressing method may cause finger pain over time. Therefore, it is very important to obtain a pen with an alternative lead-out control method. Utility Model Content
[0003] To solve at least one of the above-mentioned technical problems, this utility model provides a pen, comprising:

[0007] The control component is rotatably connected to the pen barrel via a rotating shaft.
[0008] The pen refill's mating surface is positioned in different limiting slots by rotating the control unit driven by the finger. The elastic element can be a spring, which can stably press the mating surface of the pen refill against the limiting slot, thus achieving stable writing and stable retraction.
[0009] The outer wall of the control unit is at least partially provided with a friction surface, which can increase the tactile feel during use and allows the control unit to be easily driven due to the friction surface. The limiting groove is a concave arc surface, and the mating surface between the pen refill and the limiting groove is a convex arc surface, such as a spherical surface.
[0010] The control part is an arc surface, and there are several control parts that are angled together to form a petal shape. The arc surface can cooperate with the thumb, and the petal shape can increase the aesthetics of this utility model.
[0011] The outer wall of the pen refill is provided with a driving part, and an elastic element is provided between the outer wall of the pen refill and the inner wall of the first channel. The control element moves to cause the driving part to drive the elastic element to deform. The pen refill is at least partially and stably placed in at least one limiting groove. The writing part of the pen refill extends out of or retracts into the first channel or controls the length by which the writing part of the pen refill extends out of the first channel.
[0012] The limiting groove includes at least one first limiting groove and at least one second limiting groove. The depth of the first limiting groove is configured such that the writing part of the pen refill extends out of the first channel; the depth of the second limiting groove is configured such that the writing part of the pen refill retracts into the first channel.
[0013] The pen barrel includes an outer rod and a first connecting member fixed to the outer rod. A drive groove is formed on the first connecting member. Rotation grooves are formed on the inner walls of both sides of the drive groove. The rotating shaft is fixed on both sides of the control member and is at least partially disposed in the rotation groove.
[0014] The first connector has a second channel communicating with the first channel, and the pen refill extends at least partially from the opening of the second channel and abuts against the limiting groove.
[0015] The inner wall of the second channel is provided with at least one guide groove, and the outer wall of the pen refill is provided with a guide block that mates with the guide groove. Alternatively, the guide block is formed on the inner wall of the second channel, and the guide groove is formed on the outer wall of the pen refill.
[0016] The bottom of the guide block forms a driving part for driving the deformation of the elastic element. The pen barrel also includes a pen tip fixed to the outer rod. The pen tip includes a second connector and a third connector threadedly connected to the second connector. The second connector has a limiting surface. When the elastic element is compressed, it abuts against the limiting surface and the driving part.
[0017] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, and the user rotates the control part with his thumb, which puts less pressure on the fingers compared with pressing, and repeated actions are less likely to damage the thumb.
