Multiple types of tools is used in use to complete a kind of task, very complicated.
Utility model content
The utility model proposes a kind of multipurpose high school student mathmatical ruler, solves mathmatical ruler function list in the prior art
One, inconvenient problem with use is carried, function is more, carries and use is more convenient.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
A kind of multipurpose high school student mathmatical ruler of the utility model, including main scale, the uniform imprinting in side of the main scale have
Multiple length scale lines, one end of the main scale are movably connected on secondary ruler by rotating shaft, and the uniform imprinting in outer ring of the rotating shaft has
Angle index line, the side of the rotating shaft and is correspondingly provided with standard water flat spot positioned at one end of secondary ruler, the standard water flat spot
The other end offers chalk hole, and one end of the main scale and the secondary ruler is equipped with extension plate, the other end installation of the main scale
There is an infrared lamp, one end on the main scale back side is provided with sucker, and the side of the sucker is provided with button cell, the knob
The side of button battery is electrically connected at shift knob.
As a kind of optimal technical scheme of the present utility model, the shift knob is electrically connected at the infrared lamp.
As a kind of optimal technical scheme of the present utility model, zero quarter of the standard water flat spot and the angle index line
Degree alignment.
As a kind of optimal technical scheme of the present utility model, the main scale is accommodating provided with what is be adapted with the secondary ruler
Groove.
As a kind of optimal technical scheme of the present utility model, the length scale line is made up of fluorescent material.
The beneficial effect that the utility model is reached is：By carrying out yardstick measurement provided with main scale and length scale line,
By facilitating provided with rotating shaft, angle index line, standard water flat spot and secondary ruler according to angle index line come picture triangle, circular arc
Deng figure, special angle measuring scale is eliminated the need for, by being fixed provided with sucker and chalk hole by main scale and passing through revolute pair
Chi draws circular arc, by provided with infrared lamp and shift knob, when teacher under platform can by infrared lamp come as teaching rod come
Make instruction explanation to the content on blackboard.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and a part for constitution instruction, with this practicality
New embodiment is used to explain the utility model together, does not form to limitation of the present utility model.In the accompanying drawings：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is rearview of the present utility model；
In figure：1st, extension plate；2nd, standard water flat spot；3rd, angle index line；4th, length scale line；5th, rotating shaft；6th, secondary ruler；7、
Chalk hole；8th, main scale；9th, infrared lamp；10th, shift knob；11st, button cell；12nd, sucker.
Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As shown in Figure 1-2, the utility model provides a kind of multipurpose high school student mathmatical ruler, including main scale 8, main scale 8
The uniform imprinting in side has multiple length scale lines 4, and one end of main scale 8 is movably connected on secondary ruler 6, the outer ring of rotating shaft 5 by rotating shaft 5
The uniform angled graduation mark 3 of imprinting, the side of rotating shaft 5 and is correspondingly provided with standard water flat spot 2, standard water positioned at one end of secondary ruler 6
The other end of flat spot 2 offers chalk hole 7, and one end of main scale 8 and secondary ruler 6 is equipped with extension plate 1, the other end installation of main scale 8
There is an infrared lamp 9, one end on the back side of main scale 8 is provided with sucker 12, and the side of sucker 12 is provided with button cell 11, button electricity
The side in pond 11 is electrically connected at shift knob 10.
Further, shift knob 10 is electrically connected at infrared lamp 9, for controlling the break-make of infrared lamp 9, standard water
Flat spot 2 aligns with the zero graduation of angle index line 3, is advantageous to accurate reading, and main scale 8 is accommodating provided with what is be adapted with secondary ruler 6
Groove, facilitate secondary ruler 6 to be retracted on main scale 8, avoid hindering to use, be also convenient for carrying, length scale line 4 is by fluorescent material system
Into being advantageous to see scale clearly.
This kind of multipurpose high school student's mathmatical ruler, when in use, main scale 8 and its table can directly be passed through by if desired drawing straight line
The length scale line 4 in face accurately draws straight line, if desired draws triangle, can deploy secondary ruler 6, Ran Hougen by rotating shaft 2
