Abstract
The utility model discloses a multi-purpose automatic ends for compass. The utility model is composed of a casing, a spring, an automatically interchanging mechanism, a miniature propelling pencil, and a miniature needle tube pen. The multi-purpose automatic ends for compass has two holes used for inserting pens. The miniature propelling pencil with 0.3 and 0.9 size lead cords or the needle tube pen whose thimble is 0.2 and 0.7 can be simultaneously inserted. A converting button is pressed to realize converting according to the requirement of the thickness of the drew wire.
Description
The utility model relates to a kind of drawing instrument.
Present general compasses of use of people institute, its head can only be inserted a kind of lead for retractable pencil, in the time of drawing the figure of different thicknesses line, can only change lead for retractable pencil in addition, both loses time, and disperses energy and thinking again.
The purpose of this utility model is, the prior art in the drawing field is applied on the compasses head, and it is little to make a kind of volume, can draw the Napier's compasses head of different thicknesses line graph.
The purpose of this utility model is achieved in that it is by two miniature propelling pencils or two miniature needle tubing pens, shell, spring, interchange mechanism etc. is formed automatically.Its operating principle is, before the use, connecting rod (1) is inserted on the compasses frame, as at this moment be equipped with the lead bullion core the pen (9) in user mode, and need use thin lead for retractable pencil, then by the change-over switch (14) on the bottom right pen (8), the right-hand member of interchange mechanism (5) is under the effect of (14), the clockwise direction rotation breaks away from right side bayonet socket (16) in the works, and the left end of (5) also breaks away from the upper latch notch (13) of left side pen, right pen is under the effect of (14), move down 5mm, the right-hand member of (5) enters a right upper latch notch (12), and left side pen is because the effect of spring (23) makes left side pen to top offset 5mm, (5) left end also enters left side bayonet socket (17) in the works, spring leaf (7) has the moment that (5) are rotated counterclockwise, and makes (5) two ends, the left and right sides enter (12), and is no longer mobile after (17).Otherwise operating principle is identical.Have wearing and tearing to shorten as lead for retractable pencil, only need press (10) or (11) can meet the requirements of length (the same propelling pencil of its principle).When needing needle tubing, at first to take out miniature pencil as tracing.Its principle is, presses change-over switch (14) downwards and turns right behind the bottom of (43), and the crossheading mouth takes out right propelling pencil then, and it is identical that left side pen takes out principle.Can use in the pen container (4) according to packing into during dress needle tubing with above-mentioned opposite order.
The utility model has the advantages that when drawing the different thicknesses line graph, the conversion speed of pen is fast, does not interrupt people's thinking, saves the drawing time.
