M246180 IV. Creation instructions (2), the structure of the pen core moving down requires a slight shaking to make the pen core move down into the slider 3 0 0 before writing, because the user does not understand the situation and rubs the slider 3 0 〇, causing wear and failure, and it is quite inconvenient to use. In addition, when the refill of 12 cm is manufactured, it is bent due to its long length, cannot be moved down smoothly, and even breaks and jams. The spare pen cannot be accommodated in the mechanical pencil. Refills and refills need to be carried separately, causing user distress. [New content] The main purpose of this creation is to provide a structural improvement of a mechanical pencil. It extends from a cylinder at the bottom of the cover. A sleeve is set at the bottom of the cylinder, and a plug and a lower end respectively protrude. The top surface of the plug block is also provided with a tapered hole. When the barrel is used to cover the cover, the pen core protruding from the top of the catheter is pressed down with the top surface of the tapered hole or the plug to make the pen core slip smoothly. Into the slider and protrude from the slider for the user to write. The secondary purpose of this creation is to provide a spare pen core in the aforementioned cylinder. The pen J does not need to be carried separately to avoid breakage and seizure, and is easy to use and fill quickly. [Embodiment] First of all, I would like to invite your reviewing committee to refer to the second, third, fourth, and fifth figures. This creative system consists of a shaft cylinder 10, a pen tip sleeve 20, a clamping ring 30, a slider 40, A core 50, a catheter 60, and a cover 70 with a rubber wiper 7 1 are assembled. The cover 70 is a cover provided on the top of the shaft cylinder 10, and the upper end of the nib sleeve 20 is convexly provided. The cylinder 21 is internally inserted with a sliding member 40 that can be moved in the axial direction. A constraining ring 45 and two clamping members 4 1 are arranged in the sliding member 40, and the tensioning member 41 and the sliding member 40 are interposed between each other.

M246180 IV. Creation instructions (3) One spring 42 sets, two clamping pieces 41 set one clamping ring 30, clamping ring 30 and sleeve 2 1 card set, two clamping pieces 4 1 outside There are recesses 4 4 for the steel balls 4 3 to be inserted, the clamping ring 30 and two sets of clamping members 41 from the top to the bottom, so that the steel balls 43 are fitted on the inner inclined surface 31 of the clamping ring 30, and a total of two can be contracted. The inner diameter of the clamping member 41 is to hold the pen core 50, the top surface of the clamping ring 30 is provided with a duct 60, and the duct 60 is formed by the two semi-circular pipe bodies 61, and the inside is a square The guide hole 62 and the square guide hole 62 are set into the slider 40 through the clamping ring 30 and the clamping member 41, and the restraint ring 4 5 sets of the pen core 50 are used to make the slider 40 use the spring 4 2 The reaction force is generated by the elastic force, and the pen core 50 is automatically pushed out; the improvement lies in that: the bottom of the cover 70 projects a cylinder 7 2, the bottom of the cylinder 7 2 is closed with a plug 7 3, and the plug 7 3 The upper and lower ends respectively protrude a plug rod 74 and a plug column 75. The top surface of the plug rod 74 is recessed with a tapered hole 76. The outer diameter of the plug rod 74 and the plug column 75 is the same as the inner diameter of the cylinder 72, and the plug sleeve 73 is The plug 7 4 is inserted into the bottom of the cylinder 7 2 and the cylinder 7 2 is sealed. And the inner cylinder 72 may be provisioned with a capacity cartridge 50, the cartridge 50 and the inner contact 75 disposed (as in the second figure) into the taper hole. When in use, first remove the cover 70 from the shaft cylinder 1, set the pen core 50 through the inner arc portion 6 3 of the catheter 60, and slide the pen core 50 through the guide hole 6 2 into the two clamping members 4 1 Inside, with the pen core 50 protruding from the top end of the catheter 60 (as shown in the sixth figure), and then the cover 70 is placed on the top of the shaft cylinder 10, so that the bottom face of the plug 7 5 of the plug sleeve 7 3 is pressed. The refill 50 is set down in the slider 40 to overcome the clamping force of the two clamping members 41, as shown in the second figure, so that the refill 50 is protruded from the nib of the slider 40, and For users to write;

M246180 IV. Creation Instructions (4) ^ When using a longer refill 50, set the refill into the guide hole 6 2 and the refill 5 0 0 protrudes from the duct 60 0, and reverse the sleeve 7 3 to The plug 7 5 plugs the bottom of the cylinder 7 2 so that the top of the pen core 50 extends into the tapered hole 76 and presses the pen core 50 down with the top surface of the tapered hole 7 6 to slide into the slider 40. The same can be achieved for users to write smoothly (as shown in Figure 13). The main structure of the mechanical pencil can be roughly divided into a unidirectional clamping mechanism and a sliding mechanism. The clamping mechanism is composed of the clamping ring 30, the inner inclined surface 31, the steel ball 4 3, and a set of clamping. As for the component 41, only the pen core 50 is allowed to move toward the pen tip, and the pen core 50 is not allowed to move in the reverse direction; the sliding mechanism is composed of the above-mentioned sliding mechanism and the above-mentioned slider _ 4 4 0 When bearing the reaction force exerted by the paper, the pen core 50 must be pulled down to an appropriate length, and the core length is the same as the stroke of the slider 40 when it is forced to move. The following is a list of action methods for filling the automatic pencil with the refill and the automatic refill: As long as there is no refill 50 in the pencil, first remove the cover 7 0 from the shaft 10 and then plug it. Remove the sleeve 7 3, take out the refill 50 in the cylinder 7 2 and insert it into the square guide hole 62, and then plug the sleeve 7 3 into the closed cylinder 7 2 so that the four ends of the refill 50 Side against the inner side wall of the square guide hole 62, increasing the friction between the pen core 50 and the square guide hole 62, when the user's stomach applies a force A to push the pen core 50 down (such as the first As shown in the second figure), the friction force between the pen lead 50 and the square guide hole 62 and the center of gravity of the clamping member itself make the clamping member 4 1 move down a small distance, resulting in the steel ball 4 3 along The inner inclined surface 3 1 slides into a wider place, causing the clamping members 4 1

M246180 Hook, creation instructions (5) Slightly flared outward, and lost 50 can be pushed down smoothly and stopped at about 1 ~ 2 ππη. Other external forces act on the frictional resistance of the refill 5 45, but when the user holds the existing 50, which has lost its writing function due to the reaction force b of the unidirectional braking refill 50, the force B although Greater than restraint refill 50 and refill grip 4 1 with the refill 5 〇 upward to the inner inclined surface 3 1 slide upwards into the refill 5 which is able to move upwards; due to 50 and the clamp 4 1 The upward direction is almost negligible, and the clamping mechanism of the book clamping ring 30 and the inner bevel allows only the pen to move. The nib sleeve 2 of this creation is formed on the top surface of the sleeve 2 of the nib sleeve 20— ^ slot 3 2 (shown in Figure 10), so that the catheter stands against the pen core 5 until the pen anger Q stops after the pen anger stops. Overcome the gravity of the pen's brake of the pen core 50; and Yu Shang sliding as shown in the figure, the friction effect of the ring 4 5 on the pen moves a small narrow place 'and then the steel ball 4 3 is clamped inward by the moving distance of the writer There is no duty, the bottom end of the steel ball 4 3 core 50 0 down 0, 50 0 ^, the pen core will not go wrong automatically without fail (such as the friction force applied to the pen core, with distance, so that these forces The stroke is only about 0. Feeling and clamping movement, 0 Another embodiment (such as 1 card set clamping ring 3 0 and catheter 60 set into card 60 0 set is more stable and tight, so that the pen core slightly exposed the tip of the pen Outside only by gravity 'and no 50's are subject to constrained ring slip. When writing with a pen, the refill is applied to the paper P as shown in the two figures). The tightness causes the steel ball 4 3 to be aligned along the clamping part 4 1 so that the refill 50 is not short, so the refill is within Q 1 mm. That is, the clamp 4 1 and so on, but not allowed to go up, as shown in the seventh figure), rear ’clamping ring 3 〇 groove 3 2 (as in the ninth; the nib sleeve 2 〇
