Description
Technical field
The utility model is related to a kind of instructional device, specially a kind of servicing unit of mathematical education, belongs to education section
Grind field.
Background technology
Need teaching of use instrument that auxiliary view is done on blackboard during mathematical education, what auxiliary view did can make well student
It is easier to understand, but some figures is the difficult picture of comparison in auxiliary view, are such as justified, teachers is often used when circle is drawn
To compasses, general compasses for teaching all than larger, and using when circle can not disposably be finished, need it is hand-off, very
Trouble, increased the teaching load of teachers, and the deformation of compasses also results in mapping failure when mapping.In order to solve these
Problem, we have proposed a kind of servicing unit of mathematical education.
Utility model content
The technical problems to be solved in the utility model is the defect for overcoming prior art, there is provided a kind of mathematical education it is auxiliary
Help device.
In order to solve above-mentioned technical problem, the utility model provides following technical scheme：
A kind of servicing unit of mathematical education of the utility model, including motor rack and round bearing, motor rack are fixed on
On round bearing, motor on motor rack, is fixedly connected, motor is arranged on the center of motor rack, and motor output end is fixedly connected
Switch block, the side of switch block are fixedly connected ruler, and ruler is provided with slide block, and slide block is slidably connected with ruler, slide block side centre bit
Put and be fixedly connected chalk clamp, the other end of ruler is arc end, the inner side edge of round bearing is provided with and is slided with the arc end of ruler
The chute of contact, round bearing are provided with four supports, and the bottom of support is provided with magnet, highly identical, the bottom of switch block of support
Portion is fixedly connected rotary head, and rotary head is turbination, and the bottom of the bottom of rotary head and four supports is at grade.
Further, round bearing upper center position is fixedly connected supply unit.
Further, the outer side edges of round bearing are provided with motor switch.
Further, locking pin is provided with above slide block, locking pin is threaded connection with slide block.
The beneficial effect reached by the utility model is：After diameter of a circle determines, slided on ruler by slide block
Corresponding position, then locking pin locking sliding block, can determine round home position by rotary head, and the support of round bearing is pasted
To on blackboard (blackboard now mostly adopts magnetic material), allow round bearing to be attached on blackboard, teacher is made without always
Device is lifted, the labour intensity of teacher is reduced, motor switch is then opened, motor is rotated and drives ruler to rotate, and is fixed on cunning
Chalk clamp on block can draw the circle of comparison rule with chalk.

Specific 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.
As shown in Figure 1-2, a kind of servicing unit of mathematical education, including motor rack 1 and round bearing 2, motor rack 1 are solid
It is scheduled on round bearing 2, on motor rack 1, is fixedly connected motor 3, motor is arranged on the center of motor rack 1, and motor 3 is exported
End is fixedly connected switch block 4, and the side of switch block 4 is fixedly connected ruler 5, and ruler 5 is provided with slide block 6, and slide block 6 is slided with ruler 5 and connected
Connect, 6 side center of slide block is fixedly connected chalk clamp 7, the other end of ruler 5 is arc end, the inner side edge of round bearing 2 sets
There is the chute with the arc end sliding contact of ruler 5, so can ensure that ruler 5, in a rotation with surface, makes picture bowlder
More preferably, round bearing 2 is provided with four supports 8 to stationarity, and the bottom of support 8 is provided with magnet 9, highly identical, the switch block of support 8
4 bottom is fixedly connected rotary head 10, and rotary head 10 is turbination, and the bottom of rotary head 10 is with the bottom of four supports 8 same flat
On face, drawing bowlder can make teacher only need to, with hand steered device, determine home position, and the work for reducing teacher is strong
Degree.
2 upper center position of the round bearing is fixedly connected supply unit 11, can provide electric power for motor 3, described
