Description
Technical field：
This utility model is related to a kind of mathematical function instructional device, belongs to mathematics appliance technical field.
Background technology：
Mathematics originates from the production activity of mankind's early stage, and Chaldaic have accumulated certain from remote ages
Mathematical knowledge, and practical problem can be applied. from mathematics in itself, their mathematical knowledge is also simply observed and experience gained, does not have
There are comprehensive conclusion and proof, but also will affirm fully the contribution that they make to mathematics institute.
The knowledge of background mathematics and utilization are personal with indispensable in group life parts. the essence of its basic conception
Refining is just considerable in the ancient mathematics text in ancient Egypt, Mesopotamia and ancient Gingko to be seen. from then on, its development
Just continuously there is progress by a small margin.But algebra at that time and geometry are for a long time still in independent state.
Algebra can be described as " mathematics " that people the most accept extensively.It may be said that everyone starts to learn number from as a child
Several, the mathematics touching at first is exactly algebra.And mathematics as one research " number " subject, algebra be also mathematics
One of important ingredient.Geometry is then the branch of mathematics that early start is studied by people.
Existing mathematical function instructional device, in-convenience in use adjusting, and complex operation, wastes regulating time, efficiency
Low.
Utility model content：
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of mathematical function instructional device.
A kind of mathematical function instructional device of the present utility model, it comprises framework, support feet, slide plate, screw rod, locking screw
Mother, arc block, drawstring, wire spool, mounting blocks, screw regulator；The bottom of framework is provided with support feet, and the upper and lower side of framework is equal
Slide plate is installed, slide plate is provided with chute, wear in chute and be connected to several screw rods, screw rod is provided with two locking nuts, and
Two locking nuts are respectively arranged with the interior outside of slide plate, and the inner side of screw rod is provided with arc block, the outer surface setting of arc block
Have drawstring stopper slot, one end of drawstring is connected with the left inside wall of framework, the other end of drawstring around being connected on wire spool, the right side of framework
Upper end is provided with mounting blocks, and mounting blocks are provided with screw regulator, and the lower end of screw regulator is provided with wire spool.
Preferably, the inner surface setting of described drawstring stopper slot has wearing layer.
Preferably, the outer surface of described slide plate is provided with rule.
The beneficial effects of the utility model are：Facilitate implementation quick regulation, easy to use, easy and simple to handle, high working efficiency,
Time-consuming.
Brief description：
For ease of explanation, this utility model is embodied as and accompanying drawing is described in detail by following.

Specific embodiment：
For making the purpose of this utility model, technical scheme and advantage of greater clarity, shown in accompanying drawing
Specific embodiment is describing this utility model.However, it should be understood that these descriptions are simply exemplary, and it is not intended to limit this reality
With new scope.Additionally, in the following description, eliminate the description to known features and technology, to avoid unnecessarily mixing
Confuse concept of the present utility model.
As shown in Figure 1-2, this specific embodiment employs the following technical solutions：It comprises framework 1, support feet 2, slide plate 3,
Screw rod 4, locking nut 5, arc block 6, drawstring 7, wire spool 8, mounting blocks 9, screw regulator 10；The bottom of framework 1 is provided with
Support feet 2, the upper and lower side of framework 1 is mounted on slide plate 3, slide plate 3 is provided with chute 31, wears and be connected to several screw rods in chute 31
4, screw rod 4 is provided with two locking nuts 5, and two locking nuts 5 is respectively arranged with the interior outside of slide plate 3, screw rod 4 interior
Side is provided with arc block 6, and the outer surface of arc block 6 is provided with drawstring stopper slot, and one end of drawstring 7 is connected with the left inside wall of framework 1
Connect, around being connected on wire spool 8, the upper right side of framework 1 is provided with mounting blocks 9 to the other end of drawstring 7, and mounting blocks 9 are provided with spiral shell
Bar actuator 10, the lower end of screw regulator 10 is provided with wire spool 8.
Further, the inner surface setting of described drawstring stopper slot has wearing layer.
Further, the outer surface of described slide plate 3 is provided with rule.
The operation principle of this specific embodiment is：During regulation, unclamp locking nut 5, screw rod 4 slides on slide plate 3
The lateral separation of adjusting screw rod, the longitudinal direction height of screw rod 4 is adjusted by tightening nut 5, and the screw rod 4 of such as downside is adjusted up
When, two locking nuts 5 are rotated down can be so that arc block 6 be coordinated with drawstring 7, when all of arc block 6 has all been adjusted
Cheng Hou, drawstring 7 formation function curve, rotate wire spool 8 and drawstring 7 is strained, wire spool 8 is adjusted by screw regulator 10 simultaneously
Highly, easy to use, easy and simple to handle, high working efficiency.
