Abstract

The utility model relates to a multifunctional marker. The bottom part of a main body is provided with a groove. A slide board which is provided with a group of round holes is movably inserted into the groove. A pen pipe is fixed in the round holes. A handle is installed on the main body. The utility model has the advantages of simple structure, low cost, and double functions of scribing lines and making circles and can simply, conveniently and canonically realize one lattice with two lines, three lattices with four lines, four lattices with five lines, four lattices with two lines, the circles, concentric circles, etc.

Description

Multi-purpose scriber

The utility model belongs to teaching aid, is specifically related to a kind of structure of multi-purpose scriber.

At present, draw general ruler of straight line or set square in the teaching, draw the circle compasses, drawing parallel lines adopts two set squares that article one straight line is carried out the one or many translation, more " matts ", " staff " of line bar then needs multi-pass operations, not only time-consuming, and can produce than mistake, it is very numerous to draw a plurality of concentric circless in the geometric proof.

The objective of the invention is to: design a kind of multi-purpose scriber, can simple and easy, convenient, standard realize the dual-use function of ruler and compasses.

The object of the present invention is achieved like this: the bottom part body of band handle is opened the groove of a belt grooves, and the slide plate of the band fin that coincide with the main body groove inserts groove, and one group of shaft of a writing brush is fixed in the circular hole on the slide plate.

Fig. 1 is the utility model structural representation

Among the figure: 1 handle, 2 main bodys, 3 grooves, 4 slide plates, 5 circular holes, 6 shafts of a writing brush, 7 rule pin

Introduce implementation method of the present utility model below in conjunction with accompanying drawing:

The groove 3 of a belt grooves is opened in the bottom of main body 2, and the slide plate 4 of the band fin that coincide with groove inserts the groove 3 of main bodys 2, sets up one group of circular hole 5 on the slide plate 4 separately, and the shaft of a writing brush 6 is fixedly in the circular hole 5, chalk or advise pin 7 and put into the shaft of a writing brush 6, and handle 1 is installed on the main body 2.

Chalk is put into the selected two or several shafts of a writing brush 6, hold handle 1 allow chalk lean to blackboard flat from left to right draw two lines, one lattice, three-way two lattice, five lines, four lattice, on parallel three-way two lattice hard straight again draw three-way two lattice " matts ", rule pin 7 inserts in the selected shaft of a writing brush 6, and puts chalk in the suitable shaft of a writing brush 6, with rule pin 7 stand on centring place, rotate a week " circle " or " concentric circles ".

The utility model is simple in structure, and is with low cost, and a device is all rule and justified, and easy, the standard that saves time is desirable teaching aid.
