New description: [New technical field] This creation is a refill sharpening device that uses a spring to absorb excessive external force and maintain a certain pressure. The guide post and the guide groove keep the blade holder vertically moving. The material of the suction cup 'to prevent the pen from breaking. [Prior Art] Generally, the pencils of pencils and automatic feed mechanisms have different characteristics. The engineering pens combine the advantages of two types of pencils. They can not only draw the strokes of ordinary pencils, but also facilitate the replacement of refills and adjustment of refills. Length, therefore: is gradually used by X-pass personnel in various fields, and the upper end of the guard pen is usually a small refill sharpener. Rotating grinding, but the volume and weight of the engineering pen and refill are larger than the conventional pen repeater'. Therefore, the direction of force and the force are not easy to control. When the force is too large or the direction of the force is inclined, the outer layer of the I core is not The xylem protection of the pen is easy to break, and the inner hole of the small pen is straight π: equivalent to the pen's case. Therefore, it is often difficult to take out and cause inconvenience, so further improvement is needed. M363397 [New Content] In view of the above various situations, the creator has developed a refill sharpener that is more suitable for such refills to prevent breakage of the refill. The invention is a refill sharpening device, the bottom surface of the base is provided with a spring fixing cover, the inner part is provided with a guiding column, and the inner side of the guiding column is provided with a guiding groove; a spring is arranged between the spring fixing cover and the blade fixing frame, and the blade is fixed The protrusion of the frame can be matched with the guide groove on the inner side of the guide post. When the pen core penetrates into the refill hole, the following pressure is applied to the blade holder and the external force is rotated. The spring under the blade holder can not only absorb excessive dusting force. And the blade provided with the blade holder is fixed to maintain a fixed grinding force, and the guide post and the guide groove are matched with the upper cover and the fixed sleeve to correct the non-vertical component of the skew, and the spring is fixed under the cover. The suction cup of the material can be fixed on the plane for one-handed operation, and can withstand the overall structural angular offset 'to prevent the broken core from being broken; and the creation of the upper cover is not only the main purpose of preventing the refill from breaking, but also using the spring. The force can make the slider automatically close after the transfer, (4) stop (four) ❹ 'So this creation not only has (4) anti-breaking work, but also anti-smashing. [Embodiment] The following is a description of the structure and function of the creation of the masterpiece of the creation, with the detailed description of the schema, the gentleman's understanding of the creation; this creative department - the kind of sharpener sharpener Referring to the first to _r plane, the main structure 4 M363397 comprises a base 1, a blade holder 13, a blade 14, an upper cover 2, a slider 22, a top cover 23, a fixing sleeve 24 and a suction cup 3, wherein Referring to the first to second figures, the base is internally provided with a guide post 12'. The inner side of the guide post 12 is provided with a guide groove 121, and the bottom surface is provided with a spring fixing cover. ^ The spring solid cover 11 is provided with a suction cup 3 The blade holder 13 is disposed between the two guide posts 12, and is internally provided with a blade 14. A spring is disposed between the blade holder 13 and the spring fixing cover 11. The upper cover 2 can be covered on the base 丨, and the side surface is provided. The card 掣 21 has a slider 22 in the upper groove, a spring inside the slider 22, a top cover 23 on the top surface, and a fixing sleeve 24 in the center of the top cover 23 to match the cross-sectional shape of the pen. . For the month, as shown in Fig. 1 to Fig. 6, the pen tip sharpener of this creation can be fixed to the plane with one hand for convenient one-hand operation by using the suction cup 3. For example, the pen pen of the engineering pen is extended, and the pen 8 extends the length of the pen to the length. 1 The refill is made by the fixing sleeve, pushing the slider 22' to open it to the sides, and the suction cup 3 of the soft material can make the whole structure can withstand the angular displacement of the pen to avoid the refill: The angle is the breakage before grinding, when the refill penetrates the blade holder coffee " 彳 pen contact blade 14 'user applies the following pressure to rotate the force 'blade solid frame 13 below ^ pressure spring in addition to can withstand If the external force is too large, the vertical magazine will also provide the blade 14 to maintain a fixed grinding force, and the protrusion 131' disposed on the side β of the blade holder 13 can be moved by the guide 12 and the guide groove 121. Correct the oblique knife force, so that the pen holder and the refill can maintain the vertical mouth pressure to rotate the Hanma, to avoid the broken core due to improper force, and 5 M363397 in order to increase the use of the single refining of the refill Degree, the finished tip of the reed is in a tiny plane 'not finished Fully sharp cone; after grinding, 'Pick the pen out' the spring provided inside the slider 22 is held to the sides, providing the reaction force of the slider 22 to the center, closing the refill hole to prevent the debris from falling out Pollution, because it also has a better example of the prevention of lead scraping, when it can not be used
