4. Description of Creation (1) [Technical Field to which the New Type belongs] This creation relates to a mechanical pencil structure, especially a mechanical pencil structure, which is cleverly designed through a barrel, a cone and a large eraser. 'Achieving the advantages of both in-finger pressing and pressing the cone of the pen to output ^ heart, diversified pen core replenishment pipeline, and long pen eraser. [Prior art] As shown in the ninth and tenth drawings, it is a conventional automatic wrong pen structure, which includes a stroke portion 70, a pressing portion 71, a stroke transmission portion 72, a wipe portion 80, a slider η, a The guide tube 82, a wiper receiving table 83, and a rear cap 90; Among them: The pen barrel portion 70 is used to accommodate various components in the mechanical pencil, especially the pressing portion 71, so the pen barrel portion 70 The design of the diameter is relatively large; and the pen barrel portion 70 has an inner edge surface and an outer edge surface; the pressing portion 71 is pivotally disposed between the inner and outer edge surfaces above the pen barrel portion 70. The pen core conveying portion 72 is accommodated in an inner edge surface of the pen barrel portion 70 and protrudes from a pen tip portion of the pen barrel portion 70. The pen erasing portion 80 is accommodated above the pen core transmitting portion 80 on the inner peripheral surface of the pen barrel portion 70; the pen erasing portion 80 is first accommodated in the pen invitation portion 7 with the slider 81 The inner edge surface of the upper half of 0, and then insert the guide tube 82 'in the slide member 8 丨, and the guide tube μ must also be provided with a wiper receiving table 83' in order to allow the pen to be wiped. 6 2 在The pen wiper receiving table 8 3 protrudes from the rear cap 90 on the inner edge surface above the pen barrel portion 70 via the guide barrel 82 and the slider 81 ′. When a user's finger presses the pressing portion 7 丨, the pressing portion 7 丨

4. Description of creation (2) The outer surface of the pen barrel part 70 makes a radial displacement inward, transparent touch, and pressurizes the pen core conveying part 72, so that the pen value, f, f is connected to an inclined plane. In the shifted state, the inner circle of a stroke of 60 is set to j, but it is sharpened for use. The mechanical pencil used in the pen barrel part 70 is used for conventional pencils. There are several components with complex structure and transmission [1]. Only the two elements of the slider and the guide barrel in the pen barrel can be in an angular shape (such as octagonal). Type) in order to avoid movement, because as long as these two elements rotate the spiral rotation of the pen barrel, that is, in addition, the stationery that is very important for a beginner to write is used because of the high proportion of beginners who write. The pen eraser is located in the pen structure, which not only consumes space, but also is a major deficiency in reducing the conventional structure. [2] Inconvenient refill output The refill output is required for the refill. The pressing part must be pressed when the upper part is located above the pen barrel. When the finger is usually located outside the lower part of the pen barrel, the original position of the pen must be changed. Missing thoughts and feelings affecting writers The conventional pen eraser needs to act through the telescopic movement in the inner surface of the compound. In particular, the corresponding part of the pen eraser must be turned between the sliding member and the guide cylinder, that is, the pen eraser socket cannot be placed in the pen cylinder. Telescopic. Here, the eraser can be said to be a degree of writing errors, which must occupy a considerable portion of the tube, but it needs such a complicated less space that the eraser can hold. As far as the conventional structure is concerned, I want to make the pressing part on the side of the pen barrel part, but the side, and when I usually hold the pen, the side of the hand, so I want to press the pressing part repeatedly to change the posture of the pen, which makes it annoying Use

The design that the pressing portion is provided on the side of the pen barrel portion also makes the pen barrel portion inevitable.

First, 'the user keeps the original holding pen posture and eats, middle finger = moving =' # can directly push the pasta and middle finger that were originally pressed on the pen cone 20 toward the second chamber 12 (ie palm: move Face 25 shrinks and applies pressure, and moves 丨 ❿ ^ ^ ※ After pushing a small distance, the f-pressing part 28 inside the movable tube 27 will contact the tightening ring 242 (as shown in the fourth figure B). At this point, the pen core 60 protrudes from the wheel exit portion 2 6 a short time. Then, while the movable tube 27 continues to retract (please refer to the fifth A and fifth β diagrams), the push in the movable tube 27 is pushed. When the pressing portion 28 pushes the tightening mount 242 ′, the tightening ring 242 is displaced on a plane distance b of the plurality of clips 241 and moves to a slope distance c, the plurality of clips 24i are borrowed Due to its inertially opened elastic force, the tightening ring 242 springs back without being pressed by the pressing portion 28, that is, the clip 241 does not cool the pen core 60 at this time. When the pen core 60 has extended out of the output portion 26 for a predetermined length (conventional techniques, will not be described in detail), finally, the fingers are relaxed, and the compressed elastic element 243 will The tightening ring 242 is pushed back, and the clip 241 grips the pen core 60, completing the action of sending out the pen core by retracting the fingers. As for using the long pen 33, just rotate the The extension seat 3 j, that is, the plurality of claw portions 311 of the extension seat 31 drives the long pen eraser 33 to rotate, and indirectly drives the guide portion 321 of the movable base 32 according to the spiral of the second chamber 12 The groove 122 rotates upward, so that the long pen 33 is pushed in the direction of the extending seat 31 from the inner cylinder surface of the second receiving chamber 12, and extends out of the second receiving chamber 1 through the claw portion 311. 2 for use, its component structure is simple, and the action is direct.

M261381 IV. Creation Instructions (9) Please refer to the sixth picture, this is the part about how the automatic wrong writing of this creation supplements the pen core 60. Because the convex member 22 and the positioning member 14 are locked, the force of the convex member 22 and the positioning member 14 can be greater than that, and the pen cone portion 20 can be pulled away from the first chamber of the pen barrel portion 10, Then, the pen core 60 can be supplemented by the opening 21 of the pen cone 20. , ≫ As the seventh drawing #, this is another embodiment of supplementing the pen core 60. In this embodiment, the force is greater than that of the long pen 33 connected by the movable base 32, and The long pen eraser 33 is detached from the movable base 32, so that the pen core 60 can be fed into the through hole 13 through the hole 322 of the movable base 32, and then the pen 13 passes the pen through the pen 13 The opening 21 of the tapered portion 20 enters the accommodating portion 23 and is provided for storage or use. Please refer to the eighth figure, on the outer edge surface of the pen barrel section, or the outer edge surface of: = 31, a clip bar can be set (the number is not shown on the surface, Bai Xianchenming), The clip is convenient for fixing the pen body to an easy-to-access place such as a briefcase. The functions of a book are as follows: [1] Controlling the design of a large pen with a single element on the movable base of the pen barrel can drive the large-scale = spiral motion of the upward movement of the valley interior.
