眾所周知，傳統之圓規結構主要包括有頂端相梅接之一定位桿及緣線 桿，該餘桿及繪線桿之底端分別設有—針具及筆具，鱗咖形時係以 该定位桿底端之針具穿刺定位於紙面上作為圓心、，然後再綱度施力旋動緣 線桿’使爾線桿底端之筆具於紙面场出卿。然，由於傳統之圓規係 以針”之穿做位作·心’其繪圓時之中心定位施力總是賴心穿刺形 成-個針孔洞’甚至刺損破壞紙張，這種針孔洞或破損現象在緣製數個同 心_更加明顯；再者，傳統圓規在繪圓時需進行刻度之旋動該繪線桿， 由於周圓贿施力之難以均衡，再加上騎線桿之可輯施力崎動相對 2置=使躲條畫錢斜，錢得線條辦勻，或魏線條無法對應接As is known, the traditional compass structure mainly includes a positioning rod and a edge rod of the top phase plum connection, and the bottom end of the remaining rod and the drawing rod are respectively provided with a needle and a writing tool, and the positioning is performed by the scale and the coffee. The needle at the bottom end of the rod is positioned on the paper surface as the center of the circle, and then the force is applied to rotate the edge rod to make the bottom end of the rod line on the paper surface. However, because the traditional compass is made by the needle, it is the center of the heart. When the circle is centered, the force is always puncture--a pinhole' or even a stab damage to the paper. Or the damage phenomenon is more obvious in the edge of the concentric _ more important; in addition, the traditional compasses need to be scaled to draw the line when drawing the circle, because the balance of the bribe is difficult to balance, plus the riding rod Can be applied to force Razaki relative to 2 sets = make the strips draw money, the money is evenly arranged, or the Wei line can not be connected

The positioning member 33 generates a braking effect in the holes 322, 324. Please refer to Fig. 4, the bolt The upper frame of the 34 can be further provided with a connecting belt 34A. The other end of the connecting belt 34A is fixed on the sliding plate 31 for facilitating the access of the bolt 34 or preventing it from falling. Please refer to FIG. 5 A modified embodiment in which the bolt 34 is coupled to the positioning member 33, wherein the upper end of the bolt 341 is provided with an external thread 3 from the bottom, and the through hole 331 of the positioning member 33 is correspondingly provided with an internal thread 331A. The bolt 34 and the positioning member 33 can be screwed together. When the bolt 34 is rotated downward, the bottom of the bolt 341 (without external thread) can be inserted into the positioning hole 322, 323 corresponding to the bottom plate 32 or 324, when the bolt 34 is rotated upward, the bottom of the bolt 341 can be disengaged from the positioning hole 322, 323 or 324 of the bottom plate 32, and the braking of the positioning member 33 can be released, so that the bolt 341 can be positioned. It is conveniently used on the sliding plate 31 and is prevented from falling and lost. Referring to FIGS. 6 and 6A, the multi-function safety compass device of the present invention first uses the center hole 312 of the sliding plate 31 to be zeroed, and then pulls the ball 34 up slightly to disengage the bolt 341 from the bottom plate. 32. At this time, the positioning member 33 can be released from the braking of the positioning teeth 214 and 215 of the two ends, and can be appropriately displaced, and then the sliding plate 31 is pushed to the center of the hole 312 to the radius of the circle to be drawn. The unit of the length unit 213A shown in FIG. 7 is further moved by the bolt 34 to move the positioning member 33 toward the end positioning tooth 215, and the positioning tooth 333 of the positioning member 33 abuts against the end positioning tooth 215 ( As shown in FIG. 7A, the plug 34 is then inserted downwardly into the positioning hole 324 of the bottom plate 32 (as shown in FIG. 8), and the positioning member 33 can be positioned and The slide plate 31 is restricted from being fixed to the ruler 21. Furthermore, in order to facilitate the application of various writing instruments, as shown in Fig. 8, the central perforation 312 is preferably composed of a circular vertebra perforation having a large upper diameter and a small perforation of a lower green width. Referring to Figures 9 and 10, at this time, the pen-heart of the ball pen (10) is inserted into the sliding plate 31, and the u-perforation 312' is placed on the edge surface ho.

In addition, as shown in the figure, the 4_TW_ board 31 towel, the empty e qi9 4 system 乂 - the pencil 1 〇 1 pen core 101A is inserted into the sliding plate 31 ~ puncturing 312, the same operation mode, - see (four) to _ To illustrate the production of the Cheng-turn line. The operation, such as Xian_show, borrowing material (not drawing the fan shape, not (not shown), inserting the center hole 312 into the zero return bolt 34 fixing the plate & The radius of f is straight to the other end position, and then the Γ = = =, then push the rotating plate 2 〇 to rotate the line to the desired angular position (depending on: stand one 'balance 0B) 'to continue the periphery The arc and the squall line (the sliding of the shackle 34 of the shackle to cancel the braking of the sliding plate 31, and using the pen, the 昼 line push _ 滑 峡 31 to the _ joint material diameter straight to the original zero position , that is, complete a shape of the 130-inch system. The shed full _ device in addition to the scale _, Lin, can also use the rule and angle units to balance the position of the measurement, and the rotation (four) (including sliding positioning The mechanism 30) can also be unloaded from the seat plate, so that the Wei can be used as a ruler or as a straight line = a system can be made, which is quite functional, and it can be borrowed as a figure. Separate design of the seat panel U and the side seat panels 12 and 13, and a thin plastic winch chain 123, 133 'by the hinges (2), 133 can be connected at the bottom of the age. The seat panel 1Q is folded and folded to facilitate its collection and carrying. ° In summary, the multi-functional safety compass device of the present invention utilizes the above structure to make the operation of the green circular shape relatively simple, convenient and highly efficient. And the line of the edge system is stable and consistent, and does not form pinholes or damaged paper on the paper, and has the security of access and painting operation, and another __ aspect can be assigned Better functionality* Enhancing the added value is indeed a rather excellent idea, and the invention patent application is filed according to law; however, the above description is only for the preferred embodiment of the present invention, and the technical means according to the present invention The present invention is intended to be included in the scope of the present invention. 200920611 417-001TWP-10/26 [Simplified Schematic] FIG. 1 is a perspective view of the present invention. 3 is a schematic view of the back of the sliding plate of the present invention.
