Description

A kind of Multifunctional compasses

Technical field

This utility model is related to a kind of Multifunctional compasses, belongs to mathematics teaching aid technical field.

Background technology

In education activities, in order to education activities are smoothly efficiently carried out, education activities need teaching aid often Auxiliary is carried out, it is often necessary to various mathematics teaching aid especially in maths teaching activities, compasses are exactly one kind therein, tradition Compasses be difficult in use to determine the radius of drawn circular arc, need ruler to be assisted, in-convenience in use, traditional compasses In use, compasses bipod is not fixed easily, and two foot distance defection during drawing circle changes, and can not draw the circle of closing, Traditional compasses use only as compasses, no other any functions, and practicality is single.

Therefore, it is necessary to propose a kind of Multifunctional compasses, can accurately adjust the radius of drawn circular arc, closing can be drawn Justify and use moreover it is possible to be split into ruler and pen.

Content of the invention

In order to overcome the problem in background technology, the utility model proposes a kind of Multifunctional compasses, structure design letter Single rationally the graduation mark that can pass through on ruler intuitively adjust the radius determining circular arc to be drawn, without extraneous measurement auxiliary Instrument, easy to use, after adjusting radius, fixed knob II radii fixus can be passed through, radius will not change in drawing processes Become, the fixing circular arc of radius can be drawn, picture pen and long chi can split, and long chi can use as survey tool it can also be used to draw Line segment, picture pen can use as writing pen, and using flexible and changeable, feature is strong.

To achieve these goals, this utility model is to realize according to technical scheme below：Described Multifunction circle Rule include long chi, angle, the pen cap, picture pen；Long chi side is provided with graduation mark, and centre position is provided with a T groove along long chi, Handle and foot pin are had on angle, the pen cap is provided with sleeve, fixed knob I, indicator, transverse slat, fixed knob II, T-type structure, Fixed knob I is located above sleeve, and transverse slat is located at below sleeve, and T-type structure is located at below transverse slat, and fixed knob II is located at transverse slat On, indicator is located at sleeve bottom dead ahead；Long chi left end is fixedly linked with angle, and long chi passes through T groove, T junction with the pen cap Structure is movably connected, and the pen cap can move left and right on long chi, can fix pen cap position by fixed knob II, and picture pen is arranged on set In cylinder, fixing by fixed knob I.

Described foot pin is collapsible in angle.

Described long chi adopts transparent organic glass.

The diameter of described picture pen is identical with the internal diameter size of sleeve.

The beneficial effects of the utility model：This utility model structure design advantages of simple, can be by the graduation mark on ruler Intuitively adjust the radius determining circular arc to be drawn, without extraneous measurement aid, easy to use, adjusting radius Afterwards, fixed knob II radii fixus can be passed through, radius will not change in drawing processes, the fixing circular arc of radius can be drawn, draw Figure pen and long chi can split, and long chi can use as survey tool it can also be used to setting-out section, and picture pen can make as writing pen With using flexible and changeable, feature is strong.

Brief description：

Fig. 1 is this utility model structure chart；

Fig. 2 is pen cap structure chart；

Fig. 3 is a structure chart of drawing.

In figure, the long chi of 1-, 2-T groove, 3- angle, 4- handle, 5- foot pin, 6- graduation mark, the 7- pen cap, 8- sleeve, 9- are solid Determine knob I, 10- indicator, 11- transverse slat, 12- fixed knob II, 13-T type structure, 14- picture pen.

Specific embodiment

In order that this utility model understands, understands, below in conjunction with accompanying drawing, this utility model is described in detail, with Facilitate the technical staff to understand.

As Figure 1-3, this utility model discloses a kind of Multifunctional compasses, and its technical scheme is：Described new many Function compasses include long chi 1, angle 3, the pen cap 7, picture pen 14；Long chi 1 side is provided with graduation mark 6, adjusts picture for directly perceived The radius of circular arc；Centre position is provided with a T groove 2 along long chi 1, and angle 3 has handle 4 and foot pin 5, and angle 3 is used for The center of circle of fixing circular arc, handle 4 is used for hand-held multifunctional compasses；The pen cap 7 be provided with sleeve 8, fixed knob I 9, indicator 10, Transverse slat 11, fixed knob II 12, T-type structure 13, fixed knob I 9 is located above sleeve 8, and fixed knob I 9 is used for fixing picture Pen 14；Transverse slat 11 is located at below sleeve 8, and T-type structure 13 is located at below transverse slat 11, and T-type structure 13 is used for being movably connected with T groove 2； Fixed knob II 12 is located on transverse slat 11, and fixed knob II 12 is used for fixing the position in long chi 1 for the pen cap 7；Indicator 10 is located at Sleeve 8 bottom dead ahead, for indicating the position of picture pen 14；Long chi 1 left end is fixedly linked with angle 3, for fixing fixed Position foot 3；Long chi 1 and the pen cap 7 pass through T groove 2, T-type structure 13 is movably connected, and the pen cap 7 can move left and right on long chi 1, by solid Determine knob II 12 and can fix the pen cap 7 position, picture pen 14 is arranged in sleeve 8, fixing by fixed knob I 9.
