New description: [New technical field] This creation is a two-stage refill sharpening device that uses different cutting inclinations of the first tool holder and the second tool holder to pencil The xylem and refill segments are ground and matched with a variety of different tip thicknesses to reduce grinding wear and increase the write endurance. Φ [Prior Art] Generally, pencils and pencils with automatic feed mechanisms have different characteristics. Among them, general pencils can not only change various thicknesses and techniques in drawing, but also enable students to experience different strengths and strokes when they are learning characters. relationship. However, in the use of the refill, the front end often wears out passivation, so it is necessary to use a sharpener to maintain the proper taper of the front end of the refill, and the edge of the blade or the rake of the conventional sharpener is usually at a single angle with the center of the refill. And the end of the blade will exceed the centerline of the refill. When grinding, the wood and the refill have a single slope, except that a large amount of xylem is cut off. The sharp anger is easy to break during the grinding process. Therefore, the user needs to repeatedly grind several times to have the opportunity to grind out the appropriate taper of the lead core. Based on the above defects, the conventional sharpener can easily reduce the durability and efficiency of the pencil, and therefore requires further Improvement. 3 M384109 [New Content] In view of the above various situations, the creators have developed a two-stage refill sharpener that can improve pencil durability and efficiency. The creation is a two-stage refill sharpening device, and an adjustment cam is arranged below the inner side of the base, and the upper part of the base is provided with an upper cover. The upper cover is provided with a guide post, and the guide groove below the guide post is provided. The second tool holder has a .th tool holder on the upper side; the second tool holder corresponds to and contacts the adjustment cam, and the top cover is disposed above the upper cover. In order to improve the defects of the conventional sharpener, this creation uses the first tool holder and the first: the knife holder to divide the pencil into two segments. 1 First, put the pencil into the pencil of the first knife holder: 'Put the pencil Rotate and press the external force to remove part of the wood part, so that the core is convex and then use the knob to drive the adjustment cam so that the second tool holder can adjust the tip of the pen, and also apply the external force of the rotation and depression, alone m am μ. ^ •"Dry words... This method of segmental grinding mainly relies on labor saving and reducing the consumption of the wrong pen. The secondary purpose is to produce a pencil with different taper of the xylem and the refill.

Please sign as shown in the fourth to fifth figure, before grinding the pencil 5, you can adjust the lowermost knob 43 to drive the adjustment cam 42 to rotate. At this time, because the surface of the adjustment cam 42 has different height difference, it can make the second The tool holder 4 cooperates with the guide groove to move up and down to set the pen tip; while grinding the ship pen 5, please refer to the fifth figure to the seventh figure. This creation mainly uses the first tool holder 3 and the first The second tool holder 4 grinds the wrong pen 5 points in two stages. First, the pencil 5 is placed in the pencil perforation 30 of the first tool holder 3 through the hole of the top cover 21, and the pencil 5 is subjected to a rotation and depression. Since the center distance of the edge of the first blade 31 to the pencil perforation 30 is equal to the radius of the refill 5 i, the first blade 31 can be cut only part of the wood portion 52 until the refill 51 can enter the second tool holder 4; 5 Continue to apply a force to rotate and press down to maintain a stable pressure grinding refill 51; in this segmented grinding mode, 5 M3841〇y Dijon and the first knife of the program can retain the complete refill 51, The second tool holder 4 of the second-stage program allows the contact area of the blade and the grinding object to be small during grinding, in addition to being labor-saving 'Also can reduce the loss of pencil grinding, in addition, because the first knife month and 帛 - the blade 41 has a different slanting 'to make the taper of the wooden part larger than the taper of the refill' with the lower adjustment cam 42 and the rotary (four) set refill After the sharpness, this creation can not only increase the duration of the writing of the refill or the painting, but also apply to the color of the singer.
