Abstract

The invention relates to a multifunctional drawing pencil which belongs to stationery and mainly solves the problem of a single function of a traditional pencil. The multifunctional drawing pencil comprises a pencil body, wherein the pencil body is composed of an angle gauge, a support, an eraser, an eraser bracket, an outer pencil shell, a pin shaft, a compasses leg, a lengthening bar, a steel needle and a pencil lead. The center of the annular angle gauge is provided with the support, and the support is fixedly arranged on the eraser bracket; a longitudinal groove is formed in the outer pencil shell under the eraser bracket, and two sides of the outer pencil shell of the uppermost side of the groove are provided with convex lifting lugs; the compasses leg hinged by the pin shaft is arranged between the two lifting lugs, and the surfaces of the outer pencil shell, or the compasses leg and the lengthening bar are provided with scale lines. When the multifunctional drawing pencil is used, in order to realize convenient working, the support fixing the angle gauge can also be taken down from the outer pencil shell. The multifunctional drawing pencil integrates various functions of writing, measuring, drawing lines, altering and the like so as to realize one pencil with multiple functions. The multifunctional drawing pencil has the advantages of simple structure, small size and safety and convenience in use, storage and carrying, does not occupy space, and is especially suitable for primary and secondary school students to use.

Description

A kind of Multifunctional drawing pen

Technical field

The present invention relates to a kind of stationery, specifically a kind of Multifunctional drawing pen.

Background technology

Pen is that people work, study, be usually used in the stationery of writing in life, therefore range of application is very extensive, and no matter be in work or study, also be unable to do without compasses during drawing, ruler, protractor, the instruments such as rubber, these stationery volumes are little, easily lose, deposit and carry all very inconvenient, especially compasses, it in mathematics and drawing, is the instrument for picture circle and circular arc, needle point place as center of circle anchor point is too sharp-pointed, the accident that often can scratch other article or stab the people, there is certain potential safety hazard, especially for the students of the junior years, sense of self-protection is poor, occur that dangerous probability is also higher, if the supporting leg of compasses is hidden in to the pen the inside, measuring, setting-out, the function of altering all concentrates in together, above problem just can easily solve.

Summary of the invention

The technical problem to be solved in the present invention is for the deficiencies in the prior art, and a kind of Multifunctional drawing pen is provided, and this has the function of measurement, setting-out, correction simultaneously and uses safety, is difficult for losing, being convenient to deposit and carry.

The present invention solves the technical scheme that its technical problem takes: a kind of Multifunctional drawing pen, by protractor, support, rubber, the rubber carriage, shell body, bearing pin, the compasses supporting leg, extension bar, draw point and pen core form, the protractor center of annular is provided with support, this support is inserted into the rubber center of hollow tubular and is fixed on the rubber carriage, the rubber carriage is positioned at the top of a shell body, be provided with groove on a shell body below the rubber carriage, a shell body both sides of groove top side are protruding hanger, the hinged compasses supporting leg of bearing pin is housed between two hangers, this supporting leg and extension bar are that two sections or the different hollow pipe intussusception of multistage diameter form, the draw point of sharp needle is housed at the extension bar end, compasses supporting leg after contraction, the length of extension bar and draw point is less than a shell upper groove length, pen core is arranged in a shell body, be provided with the size scale line at a shell body or compasses supporting leg and extension bar surface.

The invention has the beneficial effects as follows: integrate write, the several functions such as measurement, setting-out, correction, really realized a multipotency, simple in structure, volume is little, does not take up room, and uses, deposits, safe to carry, convenient, applied widely.

The accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

In figure: 1 protractor, 2 supports, 3 rubbers, 4 rubber carriages, 5 shell bodies, 6 bearing pins, 7 compasses supporting legs, 8 extension bars, 9 draw points, 10 pen cores.

The specific embodiment

As shown in Figure 1.A kind of Multifunctional drawing pen, comprise a body, the structure of described body is by protractor 1, support 2, rubber 3, rubber carriage 4, shell body 5, bearing pin 6, compasses supporting leg 7, extension bar 8, draw point 9 and pen core 10 form, protractor 1 center of annular is provided with support 2, this support 2 is inserted into rubber 3 centers of hollow tubular and is fixed on rubber carriage 4, rubber carriage 4 is positioned at the top of a shell body 5, be provided with the degree of depth and width longitudinally on a shell body 5 below rubber carriage 4 and all do not affect the groove that pen core 10 is installed, a shell body 5 both sides of groove top side are protruding hanger, the hinged compasses supporting leg 7 of bearing pin 6 is housed between two hangers, this supporting leg 7 and extension bar 8 are that two sections or the different hollow pipe intussusception of multistage diameter form, length can be stretched arbitrarily, the draw point 9 of sharp needle is housed at extension bar 8 ends, compasses supporting leg 7 after contraction, the length of extension bar 8 and draw point 9 should be less than a shell body 5 upper groove length, pen core 10 is arranged in a shell body 5, be provided with the size scale line at a shell body 5 or compasses supporting leg 7 and extension bar 8 surfaces.During use, the support 2 of fixed amount hornwork 1 also can take off on a shell body 5; While writing, by compasses supporting leg 7, extension bar 8 and draw point 9 rotations, to the groove in a shell body 5, holding a pen writes gets final product; As when needing picture circle or drawing arc, from bearing pin, 6 places rotate compasses supporting leg 7, make it to be with a shell 5 junctions the angle that is less than 90 degree, pull out extension bar 8, make length basically identical with the length of pen, hold the top of the pen that bearing pin 6 places are housed, using draw point 9 as the fixing center of circle, carry out setting-out with the nib of pen core 10 and get final product; Use 3 pairs of wrong places of rubber to be altered; The present invention integrate write, the several functions such as measurement, setting-out, correction, really realized a multipotency, simple in structure, volume is little, does not take up room, and uses, deposits, safe to carry, convenient, is particularly useful for students in middle and primary schools and uses.
