Abstract

The utility model discloses a compass, protractor and ruler three-in-one multi-functional tool, which comprises a compass, a protractor and a handle, and is characterized in that an arc hole is arranged within a degree graduation line of the protractor so as to facilitate two screws on the compass to make circular motion, and when the inner sideline of one leg of the compass is coincided with a zero graduation line, and the other leg is opened at an angle of any degree, the screws are tightened and the graduation number can be read from the inner sideline; particularly, when the compass opens at an angle of 180 degrees, the screws are tightened, and the handle is pulled down, the compass can be matched with the length unit of the compass and the protractor to be used as a ruler. The utility model is a multi-functional tool integrating the compass, the protractor and the ruler, has simple use, can be used as an ordinary tool, and achieves multiple purposes by buying one tool, thereby saving money and easily carrying; and the utility model is an ideal multi-functional tool, and is widely used in daily life.

Description

Compasses, protractor, ruler three-in-one multifunctional instrument

Technical field

The utility model compasses, protractor, ruler three-in-one multifunctional instrument relate to a kind of multi-purpose tool, especially can be used on aspects such as school instruction and machine-building.

Background technology

Now compasses, protractor, the ruler of being sold on the market all is independent, all get purchase piecemeal in daily life and carries, and just makes people spend more economy and carries a lot of instruments.Be with a certain instrument then can't carry out daily teaching and work if forgotten.

The utility model content;

It is the multi-purpose tool of one that the technical problem that the utility model compasses, protractor, ruler three-in-one multifunctional instrument will solve is to provide a kind of compasses, protractor, ruler of collecting, carry a lot of instrument inconveniences when avoiding using, also avoid leaving behind certain instrument and the worry of cisco unity malfunction.

The utility model compasses, protractor, ruler three-in-one multifunctional instrument comprise compasses, protractor, ruler.Protractor has a semicircular arcuate socket in the formed circular arc of number of degrees graduation mark, the intersection point of the line that the zero graduation line of protractor and an angle of 90 degrees intersect is made hollow, and the axis coinciding that rotates with the bipod of compasses, the handle of compasses is positioned at a side, and with a tubular rivet successively with compasses, protractor, the overlapping riveting of handle together.

This protractor also has a semicircular arcuate socket that is positioned at the formed circular arc of number of degrees graduation mark except the graduation mark and the number of degrees that 180 conventional degree are arranged.The straight line of protractor is along indicating long measure.

The bipod of these compasses is marked with long measure, and inclined to one side round end is made on the top of compasses, and its thickness is half of thickness of the pin of compasses, and making the overlapping back of the inclined to one side round end thickness of bipod is the thickness of a pin, and partially on the interior straight line of center when closing the feet of round end.Compasses hand rivet(ing) in a side, pull down during ruler easy to use below, do not influence the use of ruler.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model compasses, protractor, ruler three-in-one multifunctional instrument are described in further detail.

Fig. 1 is for having the compasses of screw on the utility model bipod.

Fig. 2 is for the utility model band arcuate socket and indicate long measure and the protractor of the number of degrees.

Fig. 3 is the three-in-one multifunctional instrument of compasses of the present utility model, protractor, handle composition.

The specific embodiment

Shown in Figure 3, compasses of the present utility model, protractor, ruler three-in-one multifunctional instrument are made up of protractor 1 and compasses 2 and handle 3.Protractor 1 has an arcuate socket 5 that moves in a circle for compasses at the formed circular arc of number of degrees graduation mark with interior except the conventional number of degrees graduation mark and the number of degrees are arranged.At this moment the two ends of arcuate socket 5 can just make till bipod flare up 180 degree of compasses 2, with the edge formation straight line that indicates long measure of protractor 1, pull down handle 3, the long measure on cooperation compasses 2 and the protractor 1 just is used as ruler and has been used.

Near the arcuate socket place two screws are arranged on the compasses 2 in Fig. 3.Be used for the compasses bipod and be tightened in when arbitrarily angled on the protractor 1 and nonvoluntary slip opening, bipod is loosening when particularly making ruler using when flare up 180 is spent, and is convenient to the use of ruler.

Overlapping order among Fig. 3 is compasses 1, protractor 2, handle 3 from the bottom to top.Use a tubular rivet 6 together then with their riveting.

The utility model compasses, protractor, ruler three-in-one multifunctional instrument are not limited to above-mentioned embodiment; no matter on its size, shape or structure, do any variation; every utilize compasses, protractor overlapping after; with all dropping in the protection domain of the present utility model that a tubular rivet riveting is formed together; in addition, metal material being become plastics or other hard materials also all drop on originally is in the protection domain of utility model.
