Description
Technical field
The utility model belongs to educational aid field, is specifically related to a kind of mathematical education line drawing ruler.
Background technology
The line drawn on blackboard during teaching is longer, and in order to line drawing is straight, the chi that teaching at present uses is longer, is inconvenient to carry.
Summary of the invention
The purpose of this utility model is that provide a kind of mathematical education line drawing ruler, its technical scheme is as follows in order to solve the longer problem of chi that at present teaching uses:
A kind of mathematical education line drawing ruler, it comprises two blocks of chi plates, two blocks of chi plates are slidably connected by slide rail, every block chi plate is provided with four or more wheel, one block of chi plate is provided with handle wherein, and the front side of handle is provided with pen container, in pen container, be provided with nylon brush hair, on the upside of one block of chi plate, an Antenna Type expansion link be respectively set near two ends place wherein.
The beneficial effects of the utility model are: both hands respectively hold one block of chi plate, during mobile one block of chi plate above, to maintain static by one block of chi plate below, before two blocks of chi plates are separated, block chi plate of is above maintained static, mobile one block of chi plate below, two blocks of chi plates can alternately linearly move on blackboard, a chalk is inserted in pen container, nylon brush hair effectively can clamp chalk when hand does not pin chalk, during attachable mechanical stage plate, chalk is pushed down with thumb, just continuous print straight line can be drawn on blackboard, expansion link can measure the distance with upper straight line, conveniently draw many equidistant straight lines, so this structure can by chi plate make shorter, also longer straight line can be drawn, be convenient for carrying.
accompanying drawing illustrates:
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the top view of Fig. 1.
detailed description of the invention:
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of mathematical education line drawing ruler, it comprises two blocks of chi plates 1, two blocks of chi plates 1 are slidably connected by slide rail 2, every block chi plate 1 is provided with four or more wheel 3, one block of chi plate 1 is provided with handle 4 wherein, and the front side of handle 4 is provided with pen container 5, in pen container 5, be provided with nylon brush hair 6, on the upside of one block of chi plate 1, an Antenna Type expansion link 7 be respectively set near two ends place wherein.
Described slide rail 2 adopts ball slide rail, and sliding effect is good, laborsaving.
Described wheel 3 is embedded into setting in chi plate 1, reduces chi plate 1 and the distance of blackboard, increases stability.
Handle 4 and pen container 5 can be all provided with on two blocks of chi plates 1, just two straight lines can be drawn simultaneously.
Expansion link 7 is provided with scale.
