Creation Instructions (1) [Technical Field of New Type] This creation is related to a pencil sharpener, more specifically, a pencil sharpener that can improve cutting quality, reduce product weight, and reduce production costs. Improved machine cutting mechanism. [Previous technology] Press, please cooperate with the first and second figures shown. The cutting mechanism 10 of the conventional pencil sharpener generally includes a metal crossbar bracket 11 with two pivot ears 111 protruding from each end thereof. A spiral cutter 1 3 is pivoted obliquely between the two pivot ears 111 through a pivot shaft 12 and a clasp body 1 1 2, and a convex shaft 11 3 is extended on the outer side of the pivot ear 1 1 1 and can be connected with a The handles 20 are consolidated with each other (see the third figure), so that the handles 20 can drive the spiral cutter 1 3 of the crossbar bracket 1 1 to rotate, and the other pivot ear 1 1 1 has a through The extending hole 1 1 4 further extends inwardly with a tapered groove 1 1 5 opened upwards, so that the pen to be cut can extend through the extending hole 1 1 4 into the tapered groove 1 1 5 and The rotary handle 20 is linked with the spiral cutter 1 3 to perform helical cutting, and the top stopper 1 1 6 in front of the tapered groove 1 1 6 is convexly provided with a vertical top stopper surface 1 1 7 to make the end of the pen shaft turning In the process, it has a function of continuously shifting forward against the pen shaft to complete the pen shaft with a conical inclined surface. [Content] (Technical problem to be solved) However, the cutting mechanism of the conventional pencil sharpener still has the following points that need to be improved: 1. The conventional crossbar bracket 1 1 is designed to bear the spiral cutter 1 3 pen

However, at the end of the spinning process, the pen shaft 1 4 is against the top stop surface 1 1 7 At this time, because the crossbar bracket 11 is contained in the casing and cannot be clearly seen from the outside, it will generally exceed the rotation, and the top stop surface 1 1 7 can only provide a pen 14 The lateral positioning of 1 4 1 caused the pen 14 to continue to send the pen between the grip 15 and the grip 16 as a result of the handle 20, and the force formed by the spiral cutter 1 3 turning the pen 14 Therefore, it is easy to cause the vertical movement of the pen center 1 4 1 toward the top of the top stop surface 1 1 7, which leads to excessive cutting of the entire pen 14 and waste. In view of this, the creator created an improvement of the cutting mechanism of a pencil sharpener based on a long-term research and understanding of various pencil sharpener structures, mainly by adopting the top stop surface of the top stop block of the cutting mechanism appropriately. The design of the slanting surface consists of a flat square structure with several reinforcing ribs on the side of the crossbar bracket between the two pivot ears. From the above description, I know that this work "The cutting mechanism of a pencil sharpener is modified ~
第6頁 M249835 四、創作說明（3) 良」相較於先前技術，確可達到如下之若干功效： 1 .由於本創作頂掣塊之頂掣面係採往下内斜之設計， 故當筆桿切削後之筆心頂抵該斜向頂掣面時，其不 論螺旋切刀旋削於筆桿任一傾斜面，該頂掣面均會 產生一向下之分力，使筆心可保持於水平狀態而不 致朝頂掣面上方處產生翹起之現象，故可確保筆桿 被均勻旋削，並防止筆桿過度切削之狀況。 2. 由於本創作橫桿支架之本體，係為鋁鑄材質一體成 _ 型，且其高度係與樞耳之厚度約略相等，使其橫桿 ~ 支架具有一扁平方狀之結構，其不僅可降低鋁鑄材 料之使用與高成本之負擔，且可改善原較笨重之缺 β 點，進而提昇產品之競爭力者。 3. 由於本創作在二樞耳間之側身二預定部位分別一體 成型有一加強肋，故可藉此加強肋提高橫桿支架之 抗扭強度，使其長期旋削亦不致產生任何扭轉變形 之情形。 【實施方式】 首先，請配合第四、五、六圖所示，本創作實施例中 削鉛筆機之切削機構，主要係包含有一鋁鎢材質一體成型 而成之橫桿支架30，其二端各凸設有一樞耳31，可藉一樞 _ 軸4 0將一螺旋切刀5 0樞設其上，且一樞耳3 1外側延伸有一 凸軸3 2，可與一旋把6 0相互固結（請參第八圖所示），使 _ 該旋把6 0可帶動橫桿支架3 0及其上之螺旋切刀5 0旋轉，另 >Page 6 M249835 IV. Creation Instructions (3) Good "Compared with the previous technology, it can indeed achieve the following effects: 1. The top stop surface of the top stop block of this creation is designed to be inclined downward and inward, so When the pen core cuts against the oblique top surface after cutting, the top surface of the pen will generate a downward force regardless of whether the spiral cutter is rotated on any inclined surface of the pen barrel, so that the pen center can be maintained in a horizontal state. It does not cause the phenomenon of tilting towards the top of the top stop surface, so it can ensure that the pen is evenly cut and prevent the pen from cutting excessively. 2. Because the body of this creative crossbar bracket is made of aluminum cast material and its height is about equal to the thickness of the pivot ear, the crossbar ~ bracket has a flat and square structure, which can not only Reduce the burden of the use of aluminum casting materials and high costs, and can improve the original bulky lack of β points, thereby enhancing the competitiveness of the product. 3. Since this creation has a reinforcing rib integrally formed at the two predetermined positions of the sideways between the two pivot ears, the reinforcing rib can be used to increase the torsional strength of the crossbar bracket, so that long-term turning will not cause any torsional deformation. [Embodiment] First, please match the fourth, fifth, and sixth figures. The cutting mechanism of the pencil sharpener in this creative embodiment mainly includes a cross-bar bracket 30 integrally formed of an aluminum tungsten material. Each convex is provided with a pivot ear 31, and a spiral cutter 50 can be pivoted on it by a pivot _ shaft 40, and a convex shaft 3 2 is extended outside the pivot ear 31, and can be mutually connected with a handle 6 0 Consolidate (see Figure 8), so that _ the handle 60 can drive the crossbar bracket 3 0 and the screw cutter 50 on it to rotate, another >

Creation instructions (4)-The pivot ear 3 1 has a penetrating hole 3 3 on the outside, and the penetrating hole 3 3 extends inwardly with a tapered groove 34 opened above, for the pen shaft to pass through the penetrating hole. 33 protrudes into the conical groove 3 4 and is rotated by the upper spiral cutter 50. The conical groove 3 4 is convexly provided with a top stopper 3 5 in front. The top stopper 3 5 is opposite to the conical groove 3 4 The side is convexly provided with a top stop surface 3 5 1 which can be used for timely positioning against the positioning of the pen center. Among them: the cross bar bracket 30 top stop block 35 is a downward displacement point which can force the center of the pen to push downward. The top stop surface 351 of the force is formed with a concave rotary cut portion 3 6 at the bottom of the two pivot ears 31. The height of the concave rotary cut portion 3 6 is approximately equal to the thickness of the pivot 3 1. And at the two predetermined positions of the sideways are respectively surrounded by 〆 reinforcement ribs 37 ′ are buckled by a c-shaped ring buckle 42 on the pole shaft 40 ring groove 41 on the inside of the pen's penetrating and extending end pivot ear 31, so that the spiral cut Knife 50 can be stably pivoted between 31 dipoles.

People, the horizontal The height of the pole bracket 50 is about the same as that of the pivot ear M249835 4. The thickness of the creative instructions (5) 31 is about the same, which can make the transverse pole bracket 50 have a flat and square structure and be integrated in two predetermined positions on its side. The model has a reinforcing rib 3 7 so as to improve the torsional strength of the crossbar bracket 50 0. From the above, this creation provides an effective reduction in weight and a reduction in material costs through the improvement of the overall cutting mechanism of the pencil sharpener. And the cutting mechanism of the pencil sharpener to improve the cutting quality, so that the use of the pencil sharpener is more convenient. Therefore, the design of this creation should comply with the new patent requirements and be applied in accordance with the law.
