Description

English four line chis

Technical field:

The utility model belongs to educational aid field, is specifically related to a kind of English four line chis.

Background technology:

In teaching, use at present four line chis can only draw four line lattice of constant spacing, cannot draw as required four line lattice of different spacing, make troubles to English teaching.

Utility model content:

The purpose of this utility model is to use four line chis can only draw the problem of four line lattice of constant spacing in order to solve in current teaching, and a kind of English four line chis are provided, and its technical scheme is as follows:

A kind of English four line chis, it comprises straight plate, slide rail, slide block, pen clipping device, piston rod and handle, described slide rail is arranged on a side of straight plate, and slide rail is fixedly connected with straight plate, is provided with slide block on slide rail, described pen clipping device is fixedly connected with slide block, pen clipping device and straight plate are slidably connected, are provided with many pen containers on pen clipping device, the rear and front end of pen container is open end, at a piston rod of the rear end of every pen container plant, all piston rods are fixedly connected with by handle.

The beneficial effects of the utility model are: four chalks can be inserted in four different pen containers, light pressure handle hand is released chalk by piston rod, handle is moved and on blackboard, draws four line lattice along slideway simultaneously, the spacing of four line lattice can change according to the position of inserting chalk, so can draw four line lattice of different spacing.

Brief description of the drawings:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1.

Detailed description of the invention:

See figures.1.and.2, a kind of English four line chis, it comprises straight plate 1, slide rail 2, slide block 3, pen clipping device 4, piston rod 5 and handle 6, and described slide rail 2 is arranged on a side of straight plate 1, and slide rail 2 is fixedly connected with straight plate 1, on slide rail 2, be provided with slide block 3, described pen clipping device 4 is fixedly connected with slide block 3, is provided with many pen container 4-1 on pen clipping device 4, and the rear and front end of pen container 4-1 is open end, at a piston rod 5 of the rear end of every pen container 4-1 plant, all piston rods 5 are fixedly connected with by handle 6.

The quantity of described pen container 4-1 is 3n+1 root, and wherein n is more than or equal to 3 positive integer, in the time that n equals 3, has 10 pen containers, four chalks can one, interval pen container 4-1 or two, interval pen container 4-1 arrange, adjusting range is less.

Preferably, the quantity of described pen container 4-1 is more than or equal to 19, and the spacing adjusting range of chalk is larger.
