Abstract

The utility model discloses a multipurpose compass, comprising a four-core propelling pencil, a screw head, a compass pin with a graduated scale and a handle with an eraser. The convenience is that the four-core propelling pencil is provided with four different types of core ink pencils and the corresponding toggling button can be toggled according to the required pencil types. A screw cap at the top of the compass can be combined with the screw head of the head of a compass main body and also can be taken off to separately serve as a pen. Scales are marked on the outer edge of a pin rod of the compass pin with the graduated scale, so measurement is facilitated. The pin head part is designed into a moveable pin, so the tightness degree can be controlled by rotating the small screw head. When the pin is not used, the small screw head is rotated, the moveable pin is loosened and the pin is turned over towards the inner edge of the lower end of the pin rod. The handle with the eraser is a hollow cylinder and the high-quality eraser is placed in the hollow cylinder, so error is corrected conveniently.

Description

A kind of Multifunctional compasses

Technical field

The utility model relates to a kind of stationery, relates to more specifically a kind of Multifunctional compasses.Serve many purposes, simple and direct, practicality is for length of schooling figure, art class student have brought facility.

Background technology

Existing compasses all only have picture circle function, when relating to the work such as overstriking outline line, drawing, tolerance, modification, then need to adopt other stationery, and catch up with class or outdoor drawing, to carry multiple stationery when making picture very inconvenient.

Therefore, be necessary to design a kind of Multifunctional compasses, so that only use a kind of stationery can realize the work such as overstriking outline line, drawing, tolerance, modification.

Summary of the invention

The utility model relates to a kind of Multifunctional compasses, serves many purposes, and is simple and direct, and practicality is for length of schooling figure, art class student have brought facility.

Adopt for achieving the above object following technical scheme:

A kind of Multifunctional compasses comprises four-core propelling pencil (1), screw terminal (2), with the needle of compasses (3) of rule, with the squeezing handle (4) of erasing rubber, it is characterized in that:

Four plastic core pipes are equipped with in four-core propelling pencil (1) the inside, are equipped with in each core pipe respectively that formulated core is black by a certain percentage by the carbon element of HB, 2B, 4B, 6B and other materials, and this kind core China ink can be wiped by erasing rubber.The button handsetting of respective core pipe is installed at the pencil shell, can stirs corresponding button handsetting according to required pencil model, and stir arbitrary other button handsettings, the button handsetting of originally having transferred to can rebound automatically.At the pencil shaft top hollow cylinder is arranged, inwall is carved with screw thread, is similar to the cap nut shape, and convenient screw terminal from the compasses body head takes off.This kind pencil can arbitrarily be transferred to required model pencil-lead, is used for picture, overstriking outline line, drawing.

Screw terminal (2) is installed in the subtended angle position of compasses body head, can be combined with the cap nut of four-core propelling pencil club head.

Shank outer with the needle of compasses (3) of rule indicates scale, is used for tolerance.Its syringe needle position is designed to movable stitch, and rotatable primary screw head is controlled its elasticity.Without stitch the time, rotation primary screw head is transferred loose movable stitch, with the groove turnover on stitch edge in the shank lower end; When using stitch, again stitch to be routed up from groove, rotation primary screw head tightens movable stitch.This kind design is convenient to draw, tolerance.

Squeezing handle (4) with erasing rubber is hollow circular cylinder, can put a cylindric erasing rubber in its inside, is used for revising mistake.

Compared with prior art, the utility model stationery has following advantage and beneficial effect:

The utility model has been accomplished a kind of instrument multiple use specially for length of schooling figure, art class student design, and simple and direct, practicality is for length of schooling figure, art class student have brought facility.

Description of drawings

Fig. 1 is a kind of Multifunctional compasses structural representation, and Fig. 2,3,4 is STRUCTURE DECOMPOSITION figure.

Wherein: (1)------screw terminal, (3)---with needle of compasses, (4) of rule---are with the squeezing handle of erasing rubber for four-core propelling pencil, (2).

The specific embodiment

Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Four-core propelling pencil (1) can be stirred corresponding button handsetting according to required pencil model, and stir arbitrary other button handsettings with the core China ink pencil of four kinds of different models, and the button handsetting of originally having transferred to can rebound automatically.Cap nut at its top can be combined with the screw terminal of compasses body head, draws bowlder and uses, and also can use as pencil separately when taking off;

Screw terminal (2) is installed in the subtended angle position of compasses body head, can be combined with the cap nut of four-core propelling pencil club head;

Shank outer with the needle of compasses (3) of rule indicates scale, is used for tolerance.Its syringe needle position is designed to movable stitch, and rotatable primary screw head is controlled its elasticity.Without stitch the time, rotation primary screw head is transferred loose movable stitch, with the groove turnover on stitch edge in the shank lower end; When using stitch, again stitch to be routed up from groove, rotation primary screw head tightens movable stitch.This kind design is convenient to draw, tolerance;

Claims

1. Multifunctional compasses comprises four-core propelling pencil (1), screw terminal (2), with the needle of compasses (3) of rule, with the squeezing handle (4) of erasing rubber, it is characterized in that:

Four-core propelling pencil (1) is with the core China ink pencil of four kinds of different models, can stir corresponding button handsetting according to required pencil model, cap nut at its top can be combined with the screw terminal of compasses body head, draws bowlder and uses, also desirable use as pencil separately down;

Shank outer with the needle of compasses (3) of rule indicates scale, be used for tolerance, its syringe needle position is designed to movable stitch, and rotatable primary screw head is controlled its elasticity, without stitch the time, rotation primary screw head is transferred loose movable stitch, with the groove turnover on stitch edge in the shank lower end, when using stitch, stitch is routed up from groove, rotation primary screw head tightens movable stitch again;
