M375685 五、新型說明： 【新型所屬之技術領域】 本創作揭示一種筆筒’特別是可視書寫筆具的長度來 改變筒身長度，並具有可攜帶性的筆筒。 【先前技術】 傳統上’筆筒是放置在桌面上使用，傳統筆筒的其中 —端成開放狀，以便於書寫用筆具收納於其內部，且收納 於傳統筆筒內的書寫用筆具，其筆身的局部是從筆筒的上 述開放端外露，以便於使用者辨識與取用。換言之，傳統 的筆筒的設計’是未將「攜帶性」列入設計理念中，當使 用者欲離該座位到其他的位置辦公時，譬如開會或外出洽 公時，傳統的筆筒則無法勝任，故在上述的場合中，是採 用鉛筆盒等具有可攜性的裝置來取代傳統的筆筒。 而一般市面上常見的書寫用筆具，具有各種不同的種 類，譬如一般的鉛筆、自動鉛筆、原子筆、鋼珠筆等各式 各樣的書寫筆具。其中不乏需要刨削的書寫用筆具，譬如 一般的鉛筆等。由於該類的書寫筆具需要經刨削才能使用 ，因此筆身的長度將隨著使用次數的增加而逐漸縮短，以 致於當收納於傳統的筆筒時完全没入筆筒內。由於上述的 因素，導致使用者使用上的不便，譬如因鉛筆完全没入筆 筒內而造成取用上的不便，使用者必需將手伸入筆筒內， 或以其中一隻手握持筆筒使其傾倒以倒出鉛筆，再以另一 隻手來承接經倒出的鉛筆，而上述的行爲恐有導致使用者 -4- M375685 的手受傷之虞。 【新型內容】 [新型欲解決之課題] .如同上述的說明，傳統的筆筒在使用上仍然存在若干 * 的問題。由於傳統筆筒 - 的用途主要著眼於放置於固定的位置，因此設置上完 φ 全未考慮到攜帶性的問題，雖然鉛筆盒之類的裝置可解決 此一問題，卻仍然有不盡完善之處。舉例來說，繪畫時所 使用的彩色鉛筆’由於其用途爲繪畫，故通常一套彩色鉛 筆中包含複數支不同顏色的彩色鉛筆。當在工作內進行繪 畫時’該複數支彩色鉛筆多半是收納於傳統的筆筒內，但 — 當外出繪畫時，由於傳統筆筒的攜帶性不佳，則必須以另 外的容器收納以便於攜帶。如此一來，增加了使用上的不 便利性’且由於該類型的彩色鉛筆與一般鉛筆相同，都必 φ 需經刨削後才能使用，而經刨削的筆尖在將上述鉛筆從傳 - 統筆筒移載至額外容器的過程中，恐有刺傷使用者之虞。 [解決課題之手段] 有鑒於上述的狀態’本案的申請人乃發展出一種嶄新 的筆筒，該筆筒可用來收納書寫用筆具且具有可攜帶性， 其特徵爲具備：頭部’該頭部是由筆筒蓋、削鉛筆器及木 屑收集盒所構成，並可卡合固定於筒身部的其中一側；及 筒身部’該筒身部至少由一個外筒部與一個內筒部所構成 -5- M375685 ，並形成前述內筒部可滑動自如地收納於前述外筒部內。 此外，前述的筆筒蓋還具有：掀蓋，該掀蓋設於前述 筆筒蓋的上表面；及削鉛筆器用安裝部，該削鉛筆器用安 裝部是配置於前述筆筒蓋的內部，而與前述筆筒蓋形成一 體。 除此之外，前述內筒部於其中一端一體形成有底座部 ，且該底座部至少具有一個以上的排氣孔。不僅如此，前 述內筒部，在外周的表面上形成有2個延伸於長軸方向的 滑動槽，且在該滑動槽內，至少在上下2個位置設有定位 部。 此外，在上述內筒部的其中一側，分別形成有一對定 位用彈片，且上述的一對滑動槽的局部是形成於該一對定 位用彈片的外側面上。 另外，前述的外筒部，在其中一側的端部形成有一對 按壓用彈片。 此外，上前述的外筒部，在前述一對按壓用彈片上方 的內側面，形成有一對滑軌。 [新型的效果] 根據本創作的筆筒’由於本創作的頭部可安裝於筒身 部的開口端’進而封閉筒身部而形成密閉狀的容器，故本 創作的筆筒具有良好的攜帶性。此外，當置放於桌面上使 用時’可將上述的頭部從筒身部取下，如此一來，其使用 的方式便與傳統的筆筒相同。 -6 - M375685 此外，由於本創作的筒身部至少是由一個外筒部與一 個內筒部所構成’且本創作的筒身部構成：該內筒部可自 由滑動地收納於該外筒部內’因此’即使如同一般鉛筆或 彩色鉛筆等必需經刨削方能使用的書寫筆具，本創作的筆 筒也能藉由上述的構造’配合書寫筆具的長度來伸長或縮 短筆筒整體的長度，如此一來’可避免因上述書寫筆具過 短，致使收納於筆筒時完全沒入筆筒內而導致使用上的不 便，並可避免因使用者將手伸入筆筒內取出上述筆具時誤 遭筆尖刺傷的情形產生。 【實施方式】 接下來，參考圖面的內容來說明本創作之筆筒的其中 一種實施形態。首先，第1圖爲爲顯示本創作筆筒之其中 一例的分解示意圖。第2圖爲顯示第1圖所示筆筒之筆筒 蓋的圖面。第3圖爲顯示第1圖所示筆筒之木屑收集盒的 φ 圖面。第4圖爲顯示第1圖所示筆筒之外筒部的圖面。第 . 5圖爲顯示第1圖所示筆筒之內筒部的圖面。第6圖爲顯 示第1圖所示之筆筒的使用狀態參考圖。 如第1圖所示，本創作的筆筒1是由頭部2與筒身部 3所構成。該頭部2具備：筆筒蓋21、削鉛筆器22、木 屑收集盒23及由柔軟材質所形成的緩衝墊24。而該筒身 部3則至少由一個外筒部3〗與一個內筒部32所構成。 如第1圖所示，上述的筆筒蓋21是卡合於木屑收集 盒23的上方，而該筆筒蓋21如第2圖所示設有：開口 M375685 2Ic’該開口 21c是設於筆筒蓋21的上表面，用來安裝削 鉛筆器2 2 ’並可供一般鉛筆等需經刨削的書寫筆具插入 該削鉛筆器22內進行刨削；削鉛筆器用安裝部2 1 b，該 削鉛筆器用安裝部21b是一體形成於筆筒蓋21內，用來 安裝固定上述的削鉛筆器22;及掀蓋21a，該掀蓋21a是 可自由轉動地設於筆筒蓋21的上表面，當形成關閉狀態 時可封閉上述的開口 21c。 如第1圖所示，由於筆筒蓋21是卡合於木屑收集盒 23的開口 23a，因此當使用者利用安裝於筆筒蓋21內的 削鉛筆器22來刨削鉛筆時，所產生的木屑將直接落入木 屑收集盒23內。如此一來，可避免所產生的木屑四處飛 散。 而如第3圖所示，上述的木屑收集盒23是利用設置 於其開口 2 3 a之相反側的間隙2 3 c挾持外筒部3 1的其中 一端，而套裝固定於外筒部31。 如第4圖所示，外筒部31是兩端均成開放狀的管狀 物件’在本實施形態中，該外筒部31是可自由滑動地包 覆於內筒部32的外周，換言之，該內筒部32除了形成於 底部的底座部32e以外，整體均可收納於外筒部31內。 前述外筒部31在其中一端的端部，也就是指上述被 木屑收集盒2 3之間隙2 3 c所挾持之那一側的相反側端部 ’對稱地形成有一對按壓用彈片31a、31a (由於是對稱 性的構造，故在以下的說明中，僅針對其中一側說明）。 該一對按壓用彈片3 1 a是藉由其中一側邊與外筒部3 1形 M375685 成形成連接，在該按壓用彈片31a的外表面分別形成有複 數個防滑用的突出物（在圖式的範例中爲3個突點）。在 該外筒部31的內面，於前述按壓用彈片31a的上方形成 有導軌31b。 如第5圖所示，本創作的內筒部32於其中一端一體 ' 成型有底座部32e，該底座部32e則至少具有一個以上的 排氣孔32f。換言之，本創作的內筒部32是形成：其中 φ 一端開放，而另一端封閉的筒狀容器。 此外，本創作的內筒部32，在外周的表面上形成有2 個延伸於長軸方向的滑動槽32b、32b (由於是對稱性的 構造，故在以下的說明中，僅針對其中一側說明），且在 該滑動槽3 2b內，至少在上下2個位置分別設有上端定位 ' 部32c及下端定位部32d。另外，本創作的內筒部32在 上述上端定位部32c的下方，形成有呈Π字型的定位用彈 片32a，該定位用彈片32a僅由其中一側邊連接於內筒部 φ 3 2而形成一體，並在連接內筒部3 2之那一側邊的相反側 - ，形成有剖面略呈三角形（請參考第5圖）的突起部32g ，該突起部是保持特定間隔地分別面向上述的上端定位部 32c。除此之外，上述形成於內筒部32外周的滑動槽32b ，是通過該定位用彈片32a的外表面，換言之，部分的上 述滑動槽3 2b是形成於上述定位用彈片3 2a的外周面上。 接下來，針對本實施形態之筆筒1的動作進行說明。 如以上所述，在本實施形態中，內筒部3 2除了形成 於底部的底座部32e以外，整體均可收納於外筒部31內 -9- M375685 。當內筒部32受納於外筒部31的內部時，形 31內側的滑軌31b，是嵌入形成於內筒部32 槽3 2b。如此一來，藉由使滑軌3115在滑動槽 ’可使外筒部31在內筒部32的外周自由滑動 當本實施形態的筆筒形成如第6圖（a ) 狀態時，是使滑軌3 lb沿著滑動槽32b滑動， 軌31b將接觸形成於定位用彈片32a之其中一 32g’由於該突起部 32g略呈三角形，且該 32a是以懸臂狀的結構連接於內筒部，因此隨 的持續滑動，使得該定位用彈片32a受到滑軌 而朝內筒部3 2的內側變形（壓入），接著 31b抵接於形成在內筒部32之滑動槽32b內 部32c時，便解除與定位用彈片32a之突起部 按壓關係，使得定位用彈片32a恢復至原來的 成外筒部31的滑軌31b被保持在內筒部32的 32c與定位用彈片32a的突起部32g之間，而 長的動作（請參考第6圖（a))。 相反地，當欲形成第6圖（b)所示的縮 則按壓外筒部31的按壓用彈片31a而令其抵 32的定位用彈片32a，並作用使外筒部31的 著內筒部32之滑動槽32b滑動的力量，接著 彈片32a受到按壓用彈片313的按壓而朝內情 側變形時’該定位用彈片32a上的突起部32g 述的變形而沒入內筒部32內，一旦該突起部 成於外筒部 外周的滑動 3 2 b內滑動 〇 所示的伸長 接著上述滑 端的突起部 定位用彈片 著滑軌31b 3 lb的按壓 ，當該滑軌 的上端定位 3 2g之間的 位置，而形 上端定位部 完成整個伸 回狀態時， 接於內筒部 滑軌3 1 b沿 ，當定位用 i部32的內 也將隨著上 32g沒入內 -10· M375685 筒部32內，將使上述「外筒部31的滑軌31b被 筒部32的上端定位部32c與定位用彈片32a 3 2g之間」的狀態解除，進而使外筒部31的滑肖 由上述的滑動力量，而沿著內筒部32的滑動槽 ，一旦該滑軌31b跨越過內筒部32外部的下 "32d，便完成整個縮回的動作。 ' 此外，上述形成於內筒部32之滑動槽32b φ 定位部32c，除了可與定位用彈片32a的突起部 發揮保持外筒部31之滑軌31b的定位功效，還 外筒部31的滑軌31b於跨越內筒部32的上端定 後繼續滑動而導致內外筒部分離的功效。 _ 再者，如圖面所示，由於上述的配置關係， _ 31的滑軌31b跨越內筒部32之定位用彈片32a 32g、或下端定位部32d時，將產生明顯的阻力 用者必須施加多一點的力量才能使外筒部3 1的 φ 順利地跨越內筒部32之定位用彈片32a的突起 • 或下端定位部32d而完成定位。換言之，當使用 /縮回本創作的筆筒1時，可清楚地感受到上述 衍生的定位效果，故本創作的筆筒1可穩定地形 (a ) 、（ b )所示的狀態。 以上的說明，僅是爲了說明上的方便所舉出 種實施形態，本創作並不侷限於此。只要在不逸 課題的範圍內，可有各種的設計變更。舉例來說 創作的筆筒在上述的實施形態中，是在內筒部的 保持在內 的突起部 仇31b藉 32b滑動 端定位部 內的上端 32g —起 具有防止 :位部32c 當外筒部 的突起部 ，因此使 滑軌31b 部 32g、 者欲伸長 的阻力所 成第6圖 的其中一 脫本創作 ，雖然本 上、下兩 -11 - M375685 端分別設有定位部而形成2段的伸縮構造，但本創作亦可 設至2處以上的定位部而形成2段以上的伸縮構造。M375685 V. New description: [New technical field] This creation discloses a pen holder, in particular a length of a visual writing instrument, which changes the length of the barrel and has a portable pen holder. [Prior Art] Traditionally, the pen holder is placed on a table, and the end of the conventional pen holder is open, so that the writing pen can be stored in the inside, and the pen for writing in the conventional pen holder is pen-shaped. The part of the body is exposed from the open end of the pen holder for user identification and access. In other words, the traditional pen holder design does not include "portability" in the design concept. When the user wants to leave the seat to other positions, such as a meeting or going out to work, the traditional pen holder is not competent. Therefore, in the above case, a portable device such as a pencil case is used in place of the conventional pen holder. In general, writing pens commonly used in the market have various kinds of writing instruments, such as general pencils, mechanical pencils, ball pens, ball pens, and the like. There are many writing instruments that need to be shaved, such as ordinary pencils. Since such a writing instrument needs to be shaved to be used, the length of the pen body will gradually decrease as the number of uses increases, so that it is completely immersed in the pen holder when it is housed in a conventional pen holder. Due to the above factors, the inconvenience caused by the user, such as the inconvenience caused by the pencil being completely immersed in the pen holder, the user has to put the hand into the pen holder, or hold the pen holder with one of the hands to make it fall. In order to pour out the pencil and then take the pencil that has been poured out with the other hand, the above behavior may lead to the injury of the user -4- M375685. [New content] [New problem to be solved] As with the above description, there are still several problems in the use of the conventional pen holder. Since the purpose of the traditional pen holder is mainly to focus on a fixed position, the problem of portability is not taken into account when setting up the φ. Although a device such as a pencil case can solve this problem, there are still some imperfections. . For example, the colored pencil used in painting is usually a set of color pencils containing a plurality of colored pencils of different colors because of its use for painting. When painting in the workplace, the plurality of colored pencils are mostly stored in a conventional pen holder, but — when the painting is out, the traditional pen holder must be stored in a separate container for carrying. As a result, the inconvenience in use is increased, and since the type of colored pencil is the same as a general pencil, it must be shaved before being used, and the shaved nib is used to pass the pencil from the transmission. In the process of transferring the pen holder to the extra container, there is a fear of stabbing the user. [Means for Solving the Problem] In view of the above-mentioned state, the applicant of the present invention has developed a brand-new pen holder which can be used for accommodating a writing instrument and has portability, and is characterized in that it has a head portion It is composed of a pen holder cover, a pencil sharpener and a wood chip collecting box, and can be snap-fitted to one side of the barrel portion; and the barrel portion 'the barrel portion is at least one outer tube portion and one inner tube portion The-5-M375685 is configured to form the inner tubular portion slidably housed in the outer tubular portion. Further, the above-described pen holder cover further includes: a cover provided on an upper surface of the pen holder cover; and a mounting portion for the pencil sharpener, the attachment portion for the pencil sharpener being disposed inside the pen holder cover, and the pen holder The cover is integrated. In addition, the inner tubular portion is integrally formed with a base portion at one end thereof, and the base portion has at least one vent hole. Further, in the above-described inner tubular portion, two sliding grooves extending in the longitudinal direction are formed on the outer peripheral surface, and positioning portions are provided in at least two upper and lower positions in the sliding grooves. Further, a pair of positioning elastic pieces are formed on one side of the inner cylindrical portion, and a part of the pair of sliding grooves is formed on the outer side surface of the pair of positioning elastic pieces. Further, in the outer tubular portion, a pair of pressing elastic pieces are formed at one end portion. Further, in the outer tubular portion described above, a pair of slide rails are formed on the inner side surface above the pair of pressing elastic pieces. [New effect] According to the pen holder of the present invention, since the head of the present invention can be attached to the open end of the tubular body portion and the body portion is closed to form a sealed container, the pen holder of the present invention has good portability. In addition, the above-mentioned head can be removed from the barrel when placed on a table, so that it is used in the same manner as a conventional pen holder. -6 - M375685 In addition, since the barrel portion of the present invention is composed of at least one outer tube portion and one inner tube portion, and the body portion of the present invention is constituted: the inner tube portion is slidably received in the outer tube Even if it is a writing instrument that can be used for shaving, such as a general pencil or a colored pencil, the pen holder of the present invention can extend or shorten the overall length of the pen holder by the above-described configuration 'cooperating with the length of the writing instrument. In this way, it can avoid that the writing pen is too short, so that it is completely in the pen holder when it is stored in the pen holder, which causes inconvenience in use, and can avoid being mistaken when the user puts the hand into the pen holder to take out the pen. A situation in which a pen tip is stabbed. [Embodiment] Next, an embodiment of the pen holder of the present invention will be described with reference to the contents of the drawings. First, Fig. 1 is an exploded perspective view showing an example of the pen holder of the present invention. Fig. 2 is a view showing the pen holder of the pen holder shown in Fig. 1. Fig. 3 is a view showing the φ plane of the sawdust collection box of the pen holder shown in Fig. 1. Fig. 4 is a view showing the outer tubular portion of the pen holder shown in Fig. 1. Fig. 5 is a view showing the inner tubular portion of the pen holder shown in Fig. 1. Fig. 6 is a view showing the state of use of the pen holder shown in Fig. 1. As shown in Fig. 1, the pen holder 1 of the present invention is composed of a head portion 2 and a barrel portion 3. The head 2 includes a pen holder cover 21, a pencil sharpener 22, a wood chip collecting case 23, and a cushion pad 24 made of a soft material. The tubular body portion 3 is composed of at least one outer tubular portion 3 and one inner tubular portion 32. As shown in FIG. 1, the above-described pen holder cover 21 is engaged above the wood chip collecting box 23, and the pen holder cover 21 is provided as shown in Fig. 2: an opening M375685 2Ic' is provided in the pen holder cover 21 The upper surface is used to mount the pencil sharpener 2 2 ' and can be inserted into the pencil sharpener 22 for shaving by a general pencil or the like; the pencil sharpener is mounted by the mounting portion 2 1 b, the pencil sharpening The mounting portion 21b is integrally formed in the pen holder cover 21 for mounting and fixing the above-mentioned pencil sharpener 22; and a cover 21a which is rotatably provided on the upper surface of the pen holder cover 21 when formed to be closed The above-mentioned opening 21c can be closed in the state. As shown in Fig. 1, since the pen holder cover 21 is engaged with the opening 23a of the wood chip collecting box 23, when the user uses the pencil sharpener 22 mounted in the pen holder cover 21 to shave the pencil, the generated wood chips will It falls directly into the sawdust collection box 23. In this way, the generated wood chips can be prevented from flying around. Further, as shown in Fig. 3, the above-mentioned sawdust collecting box 23 holds one end of the outer tubular portion 31 by a gap 2 3 c provided on the opposite side of the opening 2 3 a thereof, and is fitted and fixed to the outer tubular portion 31. As shown in Fig. 4, the outer tubular portion 31 is a tubular member that is open at both ends. In the present embodiment, the outer tubular portion 31 is slidably covered on the outer circumference of the inner tubular portion 32, in other words, The inner tubular portion 32 can be housed in the outer tubular portion 31 as a whole except for the base portion 32e formed at the bottom. The outer tubular portion 31 is symmetrically formed with a pair of pressing elastic pieces 31a, 31a at the end portion of one end thereof, that is, the opposite side end portion of the side held by the gap 2 3 c of the wood chip collecting box 2 3 . (Because it is a symmetrical structure, in the following description, only one side is explained). The pair of pressing elastic pieces 3 1 a are formed by connecting one side to the outer tube portion 31 1 M375685, and a plurality of anti-slip protrusions are formed on the outer surface of the pressing elastic piece 31a (in the figure). In the example of the formula, there are 3 bumps). On the inner surface of the outer tubular portion 31, a guide rail 31b is formed above the pressing elastic piece 31a. As shown in Fig. 5, the inner tubular portion 32 of the present invention is integrally formed with a base portion 32e at one end thereof, and the base portion 32e has at least one or more vent holes 32f. In other words, the inner cylindrical portion 32 of the present invention is formed into a cylindrical container in which one end of φ is open and the other end is closed. Further, in the inner cylindrical portion 32 of the present invention, two sliding grooves 32b and 32b extending in the longitudinal direction are formed on the outer peripheral surface (since the structure is symmetrical, in the following description, only one side is used. In addition, in the sliding groove 32b, the upper end positioning portion 32c and the lower end positioning portion 32d are provided at at least two upper and lower positions. Further, in the inner tubular portion 32 of the present invention, a U-shaped positioning elastic piece 32a is formed below the upper end positioning portion 32c, and the positioning elastic piece 32a is connected to the inner cylindrical portion φ 3 2 only by one side thereof. Formed integrally, and on the opposite side of the side to which the inner cylindrical portion 3 2 is connected, a projection 32g having a slightly triangular cross section (refer to FIG. 5) is formed, and the projections are respectively faced at a predetermined interval The upper end positioning portion 32c. In addition, the sliding groove 32b formed on the outer circumference of the inner cylindrical portion 32 passes through the outer surface of the positioning elastic piece 32a, in other words, the sliding groove 32b is formed on the outer circumferential surface of the positioning elastic piece 32a. on. Next, the operation of the pen holder 1 of the present embodiment will be described. As described above, in the present embodiment, the inner tubular portion 3 2 can be housed in the outer tubular portion 31 -9- M375685 as a whole except for the base portion 32e formed at the bottom portion. When the inner tubular portion 32 is received inside the outer tubular portion 31, the slide rail 31b on the inner side of the shape 31 is fitted into the inner tubular portion 32 groove 3 2b. In this manner, the outer tube portion 31 can be freely slid on the outer circumference of the inner tube portion 32 by the slide rail 3115 in the sliding groove '. When the pen holder of the present embodiment is formed in the state of Fig. 6(a), the slide rail is made. 3 lb slides along the sliding groove 32b, and the rail 31b contacts one of the 32g' formed in the positioning elastic piece 32a. Since the protruding portion 32g is slightly triangular, and the 32a is connected to the inner cylindrical portion in a cantilever structure, The continuous sliding of the positioning elastic piece 32a is deformed (pressed in) toward the inner side of the inner cylindrical portion 32 by the slide rail 32a, and then the 31b abuts against the inner portion 32c of the sliding groove 32b formed in the inner cylindrical portion 32, and is released. The sliding portion 31b of the positioning elastic piece 32a returned to the original outer cylindrical portion 31 is held between the inner tube portion 32 32c and the protruding portion 32g of the positioning elastic piece 32a, and the projection portion 32a of the positioning elastic piece 32a is pressed. Long movements (please refer to Figure 6 (a)). On the other hand, when the pressing elastic piece 31a of the outer tubular portion 31 is pressed, the positioning elastic piece 32a is pressed against the 32, and the inner cylindrical portion of the outer cylindrical portion 31 is acted upon. When the elastic piece 32a is pressed by the pressing elastic piece 313 and deformed toward the inner side, the spring 32a is deformed by the protrusion 32g on the positioning elastic piece 32a, and is immersed in the inner tube portion 32. The protrusion is formed in the sliding of the outer circumference of the outer cylinder portion 3 2 b, and the extension shown by the sliding 接着 is followed by the pressing of the projection portion of the sliding end by the sliding piece 31b 3 lb, when the upper end of the sliding rail is positioned between 3 2g Position, and when the upper end positioning portion completes the entire extended state, it is connected to the inner cylinder portion rail 3 1 b edge, and when the positioning portion i portion 32 is also immersed in the upper 32g - 10, M375685 cylinder portion 32 In the above, the state in which the slide rail 31b of the outer tubular portion 31 is between the upper end positioning portion 32c of the tubular portion 32 and the positioning elastic piece 32a32g is released, and the sliding of the outer tubular portion 31 is further caused by the above sliding Strength, along the sliding groove of the inner tubular portion 32, once the sliding rail 31b spans the inner tubular portion 3 2 External lower "32d, complete the entire retracting action. In addition, the sliding groove 32b φ positioning portion 32c formed in the inner tubular portion 32 can maintain the positioning effect of the slide rail 31b of the outer tubular portion 31 and the sliding of the outer tubular portion 31 in addition to the projection portion of the positioning elastic piece 32a. The rail 31b continues to slide after crossing the upper end of the inner tubular portion 32 to cause separation of the inner and outer tubular portions. Further, as shown in the figure, due to the above-described arrangement relationship, when the slide rail 31b of the _31 spans the positioning elastic piece 32a32g or the lower end positioning portion 32d of the inner cylindrical portion 32, significant resistance will be generated by the user. A little more force enables the φ of the outer tubular portion 3 1 to smoothly straddle the projections of the positioning elastic piece 32a of the inner cylindrical portion 32 or the lower end positioning portion 32d. In other words, when the pen holder 1 of the present creation is used/retracted, the above-described derivative positioning effect can be clearly felt, so that the pen holder 1 of the present creation can stabilize the state shown by the topography (a) and (b). The above description is merely illustrative of the convenience of the description, and the present invention is not limited thereto. There are various design changes as long as they are within the scope of the problem. For example, in the above-described embodiment, the pen holder is formed by the upper end 32g of the projection portion of the inner end portion of the inner cylinder portion, and the upper portion 32g of the sliding end portion is prevented from being raised: the projection portion 32c is a protrusion of the outer cylinder portion. Therefore, the slide rail 31b portion 32g and the resistance to be stretched are formed into one of the six drawings, although the upper and lower two -11 - M375685 ends are respectively provided with positioning portions to form a two-stage telescopic structure. However, this creation may be provided in two or more positioning portions to form two or more telescopic structures.
