AI Technical Summary
Existing pens with rotating lead ejection mechanisms have limitations on the one-way rotation between the two parts of the pen barrel during use, resulting in insufficient stability and robustness of the connection structure, which may lead to damage.
The pen refill uses a first guide groove and a limiting groove structure on the rotating tube, along with a slider and a protrusion on the pen barrel, to achieve stable switching between the extended and retracted states. The cooperation of the first slider and the second slider ensures that the relative rotation between the pen barrel and the rotating tube is unrestricted.
It reduces the risk of damage to the pen's internal structure caused by switching pen refill states, extends the pen's lifespan, and enhances the user experience through a variety of attractive designs.

TECHNICAL FIELD
[0001] The utility model relates to a writing implement field, concretely relates to a novel twist pen. BACKGROUND
[0002] The core-extracting pen is mainly divided into two kinds of pressing core-extracting and rotating core-extracting according to the core-extracting mode, wherein the rotating core-extracting mode mainly drives the sliding member in the pen to slide relative to the pen barrel by the relative rotation between the two pen barrels to push the core out of the pen, and the sliding member and the pen barrel enter the locking state by the pushing effect of the spring in the pen on the sliding member through the core, so that the core on the pen is maintained in the extended state.
[0003] Most of the rotating core-extracting pens realize the switching of the core use state (i.e. the extended state and the retracted state) in a reciprocating rotation mode during use, that is, after the core is extended out of the pen barrel by forward rotating the pen barrel, the core can be retracted into the pen barrel by reverse rotating the pen barrel. Since the relative rotation between the two parts of the pen barrel is limited in one direction, and in order to facilitate assembly, the two parts of the pen barrel are usually freely rotatable relative to each other, and the rotation limitation between the two parts of the pen barrel is realized by the connecting structure between the sliding member and the pen barrel (usually an arc slot is formed on the inner wall surface of the pen barrel, and a part of the sliding member is slidably arranged in the arc slot, so that the sliding member is driven to slide relative to the pen barrel during rotation through the arc slot), which makes the force of the relative rotation between the two parts of the pen barrel during the switching of the core use state act on the connecting structure between the pen barrel and the sliding member, affecting the stability and firmness of the connecting structure, and when the force of rotating the pen barrel is too large, the internal structure of the pen may be damaged and cannot be used.

DETAILED DESCRIPTION
[0027] The utility model will be further explained in detail below in combination with the drawings and by examples. The following examples are an explanation of the utility model, but the utility model is not limited to the following examples.
[0028] Referring to Figures 1-7 , the utility model discloses a novel twist pen, including pen holder 1 and rotation pipe 2, the cavity of pen holder 1 is slidably provided with pen core 3, and the first spring 31 for applying the force that stretches out from pen holder 1 to pen core 3 is arranged between pen core 3 and pen holder 1, and the two ends of first spring 31 are respectively abutted on pen core 3 and pen holder 1, rotation pipe 2 is sleeved and detachably installed on pen holder 1 and can rotate, the side of pen holder 1 is provided with two opposite strip holes 11, the cavity of pen holder 1 is provided with first sliding part 4, the side of first sliding part 4 is provided with the first convex column 41 corresponding with strip hole 11, and the outer end of first convex column 41 passes through strip hole 11 and is located between rotation pipe 2 and pen holder 1, and rotation pipe 2 is provided with two first guide slots 51 and two first limiting grooves 52 along the axial bending thereof, first guide slot 51 and first limiting groove 52 are alternately arranged in the form of circular ring around the central axis of rotation pipe 2, the wall surface between two first guide slots 51 is connected by the wall surface of first limiting groove 52, and the depth of first guide slot 51 is greater than the depth of first limiting groove 52, when pen core 3 is in the retracted state, first convex column 41 is abutted on the wall surface of first guide slot 51 from bottom to top.
[0029] When needing to write, rotation pipe 2 is rotated relative to pen holder 1, so that first convex column 41 moves out of first guide slot 51 and enters first limiting groove 52, due to the depth difference between first guide slot 51 and first limiting groove 52, first sliding seat is slid relative to pen holder 1, so as to push pen core 3 out of pen holder 1, and at this time, first spring 31 is in the compressed state.
[0030] When writing is finished, rotation pipe 2 is rotated again, so that first convex column 41 moves out of first limiting groove 52 and enters first guide slot 51, so that pen core 3 is stretched into pen holder 1 under the action of the restoring force of first spring 31, and first sliding part 4 is reset under the pushing of pen core 3.
[0031] In the embodiment, the pen holder 1 and the rotation pipe 2 are connected through a buckle structure.
[0032] Referring to Figure 1 , Figure 2 , the bottom end of the pen holder 1 is detachably connected with a sharp sleeve 61, which ensures the user's viewing field of the writing traces during writing, and also facilitates the replacement of the pen core 3 in the pen holder 1.
[0033] In this embodiment, the pen barrel 1 and the tip sleeve 61 are connected by a threaded structure.
[0034] See Figure 2 , Figure 3 The lower part of the pen barrel 1 is fitted with a rubber sleeve 62, which increases the friction between the fingers and the pen barrel 1, ensuring the user's grip strength on the pen barrel 1, thereby improving the user's control over the pen when writing.
[0035] See Figures 2-4 The top end of either of the two strip holes 11 extends axially along the pen barrel 1 to the edge of the top end of the pen barrel 1. A first slot 42 is provided on the bottom surface of the first slider 4, so that the bottom end of the first slider 4 is divided into left and right parts. The two first protrusions 41 are symmetrically arranged on the left and right sides relative to the first slot 42. When the first slider 4 is installed on the pen barrel 1, the two parts at the bottom end of the first slider 4 can be brought together by external force, thereby reducing the diameter of the bottom end of the first slider 4, so that the bottom end of the first slider 4 can be inserted from the top end of the pen barrel 1, reducing the installation difficulty of the first slider 4 on the pen barrel 1.
[0036] See Figures 2-7 The pen barrel 1 has a second sliding member 7 inside its cavity. The second sliding member 7 is located directly above the first sliding member 4. A second spring 71 is provided between the second sliding member 7 and the pen barrel 1 to apply a force to the second sliding member 7 that extends into the pen barrel 1. The two ends of the second spring 71 abut against the second sliding member 7 and the pen barrel 1, respectively. The side of the second sliding member 7 has a second protrusion 72 that corresponds one-to-one with the strip hole 11. The outer end of the second protrusion 72 passes through the strip hole 11 and is located between the rotating tube 2 and the pen barrel 1. The rotating tube 2 has a second guide groove 81 that is symmetrically arranged vertically with the first guide groove 51 and a second limiting groove 82 that is symmetrically arranged vertically with the first limiting groove 52. The top end of the second sliding member 7 passes through the pen barrel 1 and protrudes from the pen barrel 1. A detachable shaping member 9 is installed on the top end of the second sliding member 7. When the pen core 3 is in the retracted state, the shaping member 9 is located inside the cavity of the rotating tube 2 and the second protrusion 72 abuts against the wall of the second guide groove 81 from top to bottom.
[0037] In the process of rotating the rotating rod relative to the pen barrel 1, the second protruding column 72 can move between the second guide groove 81 and the second limiting groove 82 in sequence, so that the second sliding piece 7 reciprocatingly slides relative to the pen barrel 1, the effect of switching between the two states of the styling piece 9 extending out of the pen barrel 1 and retracting into the pen barrel 1 is realized, so as to achieve the purpose that the state of the pen core 3 on the pen barrel 1 corresponds to the styling piece 9 (i.e. when the pen core 3 on the pen barrel 1 is in the retracted state, the styling piece 9 is retracted in the cavity of the rotating tube 2, and when the pen core 3 is in the extended state, the styling piece 9 extends out of the rotating tube 2), so that the user can directly know the state of the pen core 3 on the pen barrel 1 by checking the positional relationship between the styling piece 9 and the pen barrel 1, and the risk of damage of the pen core 3 caused by long-time exposure when the pen is not used is reduced.
[0038] In the embodiment, the connection between the styling piece 9 and the second sliding piece 7 can be achieved in the form of interference fit.
[0039] Referring to Figures 5-6 , the first guide groove 51 and the first limiting groove 52 are both left-right symmetrical structures, which not only reduce the processing difficulty, but also ensure the stability and smoothness of the first protruding column 41 moving along the first guide groove 51 and the first limiting groove 52 during the switching process of the use state of the pen core 3.
[0040] Referring to Figure 2 , Figure 7 , the bottom surface of the second sliding piece 7 is provided with a second slot hole 73, and the two second protruding columns 72 are arranged left-right symmetrically relative to the second slot hole 73, the top end of the pen barrel 1 is sleeved and detachably connected with a cover 63, the top end of the second sliding piece 7 is penetrated through the cover 63, and the spring is located between the second sliding piece 7 and the cover 63, thereby preventing the second sliding piece 7 from being separated from the pen barrel 1.
[0041] Among them, the side surface of the cover 63 is provided with a pattern, and the side surface of the rotating tube 2 is provided with a through hole 21 for exposing the pattern, in the process of rotating the rotating tube 2 relative to the pen barrel 1, the pattern exposed on the through hole 21 can be changed, which not only increases the richness of the visual effect of the appearance of the pen, but also improves the interestingness of the use of the pen.
[0042] In the embodiment, the through hole 21 has two, and the two through holes 21 are arranged left-right symmetrically relative to the pen barrel 1.
[0043] The above described in the specification of the present application is only an example of the present application. Those skilled in the art of the present application can make various modifications or supplements or use similar ways to replace the described specific embodiments, as long as they do not deviate from the content of the specification of the present application or exceed the scope defined by the claims, and they should belong to the protection scope of the present application.
