Abstract

The utility model provides a convenient compass, which comprises a locating leg and a pen leg. Wherein, a moveable pen sheath is arranged at a lower end of the pen leg and provided with a large and a small pen sheath tube vertical with each other, which are mounted into a pen sheath holder at a lower end of the pen leg through a pen sheath folding and unfolding gear. In the convenient compass, a common writing pen is plugged into the pen sheath tube of the moveable pen sheath. The pen sheath folding and unfolding gear rotated to drive a fixing screw rod of the moveable pen sheath to push the pen sheath tube to move towards the pen sheath holder. The pen is clamped by a concave pen clip opening to draw. Drawing pens of two different diameters can be clamped and inserted by changing direction of the pen sheath tube of the moveable pen sheath. The compass ensures flexible and convenient drawing and adapts to different occasions.

Description

A kind of Convenient compasses

Technical field

The utility model belongs to a kind of Geometric figure drawing instrument.

Background technology

Existing compasses, its leg generally are to adopt fixing supporting good sandwich head or ink nib, close at some field boundary and use inconvenience, especially adorn the ink inconvenience.For this reason, some have occurred and can press from both sides the compasses of general writing pen, but can only press from both sides a kind of pen of specification, needed picture different thicknesses lines at some, and need to use the field boundary of the different penholders of thickness to close so inconvenient in addition at a leg.

Summary of the invention

The purpose of this utility model provides a kind of its leg can press from both sides a Convenient compasses of drawing of inserting two kinds of diameter specifications that vary in size.

This makes things convenient for its structure of compasses to have a pilot pin leg and leg, a movable pen cap is equipped with in the lower end that it is characterized in that said leg, this activity pen cap has small one and large one two orthogonal pen cap tubes, and has a standing screw, the movable pen cap is assemblied in the pen cap seat of a leg lower end by a pen cap folding and unfolding gear, said pen cap seat is by U type pen container cover for seat, pen cap folding and unfolding gear cover for seat and screw rod cover constitute, the standing screw of the movable pen cap passes the screw hole on the U type pen container cover for seat, insert among the screw rod cover after passing the screwed hole that is contained in the pen cap folding and unfolding gear centre in the pen cap folding and unfolding gear cover for seat again, have the pen clip recess at the two ends up and down of U type pen container cover for seat.

Make things convenient in the compasses at this, in the pen cap tube with the general lettering pen insertion activity pen cap, the standing screw that rotates the pen cap folding and unfolding gear drive activity pen cap makes pen cap tube pass to U type pen container cover for seat, and the pen clip recess at two ends is tight with pen clip about U type pen container cover for seat, can draw.The direction of the pen cap tube of the conversion activity pen cap can be pressed from both sides the drawing pen of inserting another kind of diameter specifications.It is flexible that these compasses are inserted drawing, can adapt to various use field boundary and close.

Description of drawings

Fig. 1 makes things convenient for the three-dimensional structure diagram of a kind of user mode of compasses (but plug-in mounting is than major diameter drawing pen) for this;

Fig. 2 makes things convenient for the three-dimensional structure diagram of the another kind of user modes of compasses (but plug-in mounting is than minor diameter drawing pen) for this;

Fig. 3 makes things convenient for the movable pen cap parts three-dimensional structure diagram of compasses for this;

Fig. 4 makes things convenient for a pin components three-dimensional structure diagram of compasses for this.

Among the figure, 1 is the pilot pin leg of compasses, and 2 is a leg of compasses, and 3 is the movable pen cap, 4 is pen cap folding and unfolding gear, 5 is compasses head, and 6 is size folding and unfolding gear, and 21 is the U type pen container cover for seat of the movable pen cap, 22 is the pen cap folding and unfolding gear cover for seat of the movable pen cap, 23 is the screw rod cover of the movable pen cap, and 211 are the pen clip recess, and 31 is the standing screw of the movable pen cap.

The specific embodiment

As Fig. 1 or shown in Figure 2, this makes things convenient for compasses to have a pilot pin leg 1 and a leg 2, a pilot pin leg 1 and a leg 2 are assemblied among the compasses head 5, size folding and unfolding gear 6 is in order to adjust the opening and closing size of compasses two legs, the lower end of leg 2 has by U type pen container cover for seat 21, pen cap folding and unfolding gear cover for seat 22 and screw rod cover 23 pen cap seats that constitute, as shown in Figure 4.The movable pen cap 3 is installed on the pen cap seat by pen cap folding and unfolding gear 4, pen cap folding and unfolding gear 4 is installed in the pen cap folding and unfolding gear cover for seat 22 of pen cap seat, the standing screw 31 of the movable pen cap 3 passes the screw hole on the U type pen container cover for seat 21, insert among the screw rod cover 23 after passing the screwed hole at pen cap folding and unfolding gear 4 centers that are installed in the pen cap folding and unfolding gear cover for seat 22 again, rotate the standing screw that pen cap folding and unfolding gear can the driving activity pen cap pen cap tube passed to U type pen container cover for seat, and make U type pen container cover for seat up and down the pen clip recess 211 at two ends shift to pen cap tube.On the movable pen cap mutually perpendicular small one and large one two pen cap tubes are arranged, can adjust the direction of pen cap tube as required, as be adjusted to plug-in mounting shown in Figure 1 state, perhaps be adjusted to as shown in Figure 2 plug-in mounting than the state of minor diameter drawing pen than the major diameter drawing pen.
