Description

A kind of compasses

Technical field

The utility model is related to a kind of drawing tool, especially a kind of compasses.

Background technology

Compasses are a kind of common drawing tools, and still, existing compasses can only install a kind of drawing pen of color, because This, can only a kind of circle of color then need to disassemble original drawing pen, then weigh to draw the circle of other colors The drawing pen of other colors is newly installed, can just draw the circle of other colors later, it is very inconvenient to operate.

Invention content

Problem to be solved in the utility model is：A kind of simple in structure, easy to operate, energy quick-replaceable different colours are provided Drawing pen to Fast Drawing different colours circle compasses.

To solve the above-mentioned problems, the compasses of the utility model, including shaft seat, the shaft seat are equipped with shaft, institute It states and is hinged with left rule leg and right compass leg in shaft, fixed on the top surface of the shaft seat there are one handrail, the bottoms of the left rule leg Portion is set there are one slide opening, sets that there are one sliding blocks in the slide opening, and a buffering is connected between the sliding block and the bottom surface of slide opening Spring, it is fixed there are one compasses needle on the bottom surface of the sliding block, inserted with a bolt on the right compass leg, covered on the bolt It connects there are one cylindrical sleeve, is respectively and fixedly provided with a block baffle at left and right sides of the sleeve, on the bolt there are one sockets The fixing nut of fixes sleeve, the fixing nut are posted by the baffle on the right side of sleeve, on the periphery of the sleeve Several hoodle holes are furnished with, a support spring are equipped in each hoodle hole, there are one the top fixations of the support spring Hoodle, on the sleeve socket be evenly equipped with several hemispheric location holes, institute on the periphery of the turntable there are one turntable It states and is evenly equipped with several pens cap in the disk of turntable, the drawing pen inserted with a different colours in each pen cap, the positioning The quantity in hole, hoodle and the pen cap is equal and corresponds, and the location hole is mutually matched with hoodle, the corresponding pen cap and positioning Hole is located at the same of turntable diametrically.

In order to compress the drawing pen in the pen cap, the compasses of the utility model are pressed inserted with one on each pen cap The outer end of tight bar, the compressor arm is fixed there are one block, and tension bullet is socketed on the compressor arm between the block and the pen cap One end of spring, the back-moving spring is connected in block, and other end is connected with the pen cap.

It is displaced outwardly for the ease of pulling block and compressor arm, the compasses of the utility model, is respectively and fixedly provided on the block One draw ring.

Turntable is deviate from from sleeve in order to prevent, the compasses of the utility model, the baffle be circle, the baffle it is straight Diameter is more than the diameter of sleeve.

For the ease of being rotated and being adjusted to fixing nut, the compasses of the utility model, the fixing nut is ingot Nut.

The utility model obtain advantageous effect be：(1) simple in structure；(2) when the circle for needing to draw a certain specific color When, the drawing pen of the color is turned to the bottom of turntable by rotary turnplate, then according to the half of the circle to be drawn Diameter adjusts the distance between drawing pen and compasses needle of the color, keeps the distance equal with the radius of the circle to be drawn, later It holds the handrail, centered on compasses needle, rotates a circle, you can the circle for drawing the color, when needing to draw another color When circle, rotary turnplate rotates the drawing pen of another color to the bottom of turntable, you can draw another face The circle of color, and so on, according to the method described above, a variety of different colours circles can be drawn, compared with existing compasses, this practicality is new The compasses of type, the drawing pen of the energy a variety of different colours of rapid translating, draw the circle of a variety of different colours, and conversion speed is fast, draw It is efficient；(3) it is set in slide opening there are one sliding block, a buffer spring is connected between sliding block and the bottom surface of slide opening, compasses needle is solid Due on sliding block, during drawing circle, compasses needle can be moved up and down with sliding block along slide opening, and have good resiliency Can, it thus can be adjusted according to the highly automated height to compasses needle of drawing pen, make the needle point and drawing pen of compasses needle Pen tip is in same level, to the drawing of more accurate completion circle；(4) if being evenly equipped on the periphery of sleeve A hoodle is done, is evenly equipped with several location holes on the periphery of turntable, location hole matches with hoodle, the pen cap, location hole and bullet Pearl quantity is equal and corresponds, thus by the cooperation of hoodle and location hole, the drawing pen of each color on turntable To be locked to the position of bottom, so that it is guaranteed that the drawing pen of each color will not be rotated arbitrarily during drawing circle, To preferably complete to paint sired results work；(5) inserted with a compressor arm on the pen cap, thus pass through the pulling force of back-moving spring, energy Make tie rod is firm to be pressed on drawing pen, drawing pen is avoided to be slided along the pen cap；(6) draw ring is respectively and fixedly provided on block, Convenient for pulling compressor arm that the pulling force of back-moving spring is overcome to be displaced outwardly, and then facilitate opposite position between adjustment drawing pen and the pen cap It sets；(7) baffle is circle, and the diameter of baffle is more than the diameter of sleeve, thus can effectively be blocked to turntable, avoids turntable Deviate from from sleeve；(8) fixing nut is wing nut, thus convenient for rotation and adjustment.
