Description
Technical field
This utility model relates to sucker type compass technical field, is specially a kind of Higher Mathematics Teaching sucker type compass.
Background technology
Compasses, in mathematics and drawing, are used to draw circle or the instrument of string, are usually used in construction with ruler and compasses, and making of compasses is logical
It it is often metal.And common compasses generally use syringe needle as the center of circle, on blackboard during mapping, the center of circle cannot be fixed, and causes
The circle drawn is lack of standardization, affects teaching efficiency, and common compasses are the most all to use screw to fix chalk, although fixing
The tightest, but cause chalk to fracture because of the most excessive sometimes, cause the waste of resource, and common compasses can not directly be drawn same
Heart circle and the circle of appointment radius, in-convenience in use.
Summary of the invention
The purpose of this utility model is to provide a kind of Higher Mathematics Teaching sucker type compass, to solve above-mentioned background skill
The inconvenient problem with use proposed in art.
For achieving the above object, this utility model provides following technical scheme: a kind of Higher Mathematics Teaching sucked type is round
Rule, including compasses rule head, semicolumn jacket cylinder and sucker, described compasses rule head is provided with anti-slip veins, and described compasses rule head is installed
Above regulation foot clamping plate, it is logical that described regulation foot clamping plate are arranged on left regulation foot and the top of right regulation foot, described left regulation foot and right regulation foot
Crossing rotating dog to be arranged on regulation foot clamping plate, be provided with rule between described left regulation foot and right regulation foot, one end of described rule leads to
Scaleover chi knob is arranged in left regulation foot, and the other end of described rule is arranged on right regulation foot by fixed plate and fastening screw
On, and fixed plate and fastening screw be arranged in right regulation foot, described semicolumn jacket cylinder is by being threadably mounted under right regulation foot
Side, described sucker is arranged on the lower section of ball fixing device, and described ball fixing device is arranged on the lower section of left regulation foot.
Preferably, described sucker is arranged in ball fixing device by rotational circle bat.
Preferably, described semicolumn jacket cylinder is provided with arc buckle.
Preferably, described rule is provided with standby semicolumn jacket cylinder, and standby semicolumn jacket cylinder passes through fixed plate
Installing on the scale with fastening screw, described standby semicolumn jacket cylinder is provided with chalk.
Preferably, described sucker is PVC plastic glue sucker or the one of magnetic chuck.
Compared with prior art, the beneficial effects of the utility model are: this utility model uses sucker to fix the circle of compasses
The heart, not only can prevent the center of circle from rocking, it is possible to avoid the unexpected injury that common needle-like compasses bring, convenient and practical, and chalk is inserting
Time in semicolumn jacket cylinder, fix with arc buckle, conveniently buckle and open, use arc to damage powder when chalk can be avoided to clamp
Pen, standby semicolumn jacket cylinder can be fixed on the scale, coordinates the concentric circular that can draw certain radius with semicolumn jacket cylinder,
Left regulation foot uses rotational circle bat to be rotated, and does not block sense, convenient and swift.
