Abstract

The utility model relates to a pair of compasses with a blade. The pair of compasses comprises a locating leg, a rotating handle, a circle drawing leg, the blade, a blade clamp, a plugging handle, clamping columns and a lead clamp, and is characterized in that two sections of clamping columns are symmetrically and fixedly arranged at two ends of the plugging handle, one blade clamp and one lead clamp are respectively and fixedly arranged at two ends of the two sections of clamping columns, the blade clamp is located on the same axis as the plugging handle, the clamping columns and the lead clamp, the circle drawing leg is a four-ridge cylinder, the circle drawing leg and the clamping columns are sleeved and connected in a matching manner, and a plurality of protrusions are arranged on the outer surface of the plugging handle. When a circle needs to be drawn by using a lead refill, the lead refill is exposed outside; when a circle needs to be obtained through cutting by using the pair of compasses, the plugging handle is held with a hand, the end with the blade is pulled out, and the other end is arranged on the circle drawing leg, so that the pair of compasses can be used for cutting a circumference; and in addition, because the circle drawing leg is hollow, the circle drawing leg can be used for storing some lead refill for later use.

Description

A kind of compasses of band blade

Technical field

The utility model relates to a kind of compasses, is specifically related to a kind of compasses of band blade.

Background technology

Compasses are one of student and scientific research personnel's common tool; Common compasses can only have the function of picture circle; If want to shear a circular scraps of paper or plastic sheet, sheet rubber; Can only on the scraps of paper that will shear or plastic sheet, sheet rubber, draw a circle earlier and use scissor cut again, even very clever people also is difficult to cut very roundly; China application (patent) numbers 200320110802.5 is called the compasses of cyclotomy " can " and China and applies for (patent) numbers 200920264959.0; Name is called " compasses of band blade anchor clamps " though improve to some extent; But without blade the time with blade can put nowhere; Have certain danger, lose easily again if be placed in other box.

Summary of the invention

The purpose of the utility model is the deficiency to prior art, and a kind of compasses of band blade are provided.

The purpose of the utility model realizes through following technological means: a kind of compasses of band blade; Comprise location leg, swing handle, picture circle leg, blade, folder cutter holder, plug handle, clamp column, the plumbous folder of folder; It is characterized in that: the two ends that are fixedly installed on the plug handle of two joint clamp column symmetries; A folder cutter holder and the plumbous two ends that are fixedly installed on two joint clamp column respectively that press from both sides of folder, the folder cutter holder is clipped on the same axis with plug handle, clamp column, folder lead.

Said picture circle leg is four distracted tubes, draws the socket of circle leg and clamp column coupling.

On the outer surface of said plug handle, be provided with several convexities.

Draw bowlder when needs with lead for retractable pencil, just lead for retractable pencil is exposed, when needs cut a bowlder with compasses; Hand-held plug handle is extracted of band blade, and it is available its cutting circumference that the other end is installed on the picture circle leg, in addition; Because it is hollow drawing the circle leg, it is subsequent use to store some lead for retractable pencils.

The utility model is simple in structure in addition, manufacturing cost and use cost are all lower, easy to manufacture, very easily promotes.Although combine accompanying drawing that the preferred embodiment of the utility model is described above; But the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, these all belong within the protection domain of the utility model.

Description of drawings

Accompanying drawing is the structural representation of the utility model;

Among the figure, the 1-draw point, 2-locatees leg, and 3-swing handle, 4-are drawn the circle leg, the 5-blade, 6-presss from both sides cutter holder, and 7-plugs handle, 8-clamp column, the plumbous folder of 9-folder, 10-lead for retractable pencil.

The specific embodiment

Below in conjunction with the description of drawings and the specific embodiment the utility model is done further to describe in detail:

As shown in the figure; A kind of compasses of band blade; Comprise location leg 2, swing handle 3, picture circle leg 4, blade 5, folder cutter holder 6, plug handle 7, clamp column 8, folder lead folder 9; It is characterized in that: the two ends that are fixedly installed on plug handle 7 of two joint clamp column 8 symmetries, folder cutter holder 6 and a plumbous folder 9 of folder are fixedly installed on the two ends of two joint clamp column 8 respectively, folder cutter holder 6 with plug handle 7, clamp column 8, folder is plumbous presss from both sides 9 on same axis.

Said picture circle leg 4 is four distracted tubes, draws circle leg 4 and clamp column 8 coupling sockets.

On the outer surface of said plug handle 7, be provided with several convexities.

Draw bowlders when needs with lead for retractable pencil 10, just lead for retractable pencil 10 is exposed, when needs cut a bowlder with compasses, hand-held plug handle 7 is extracted of band blade 5, and it is that available its cuts circumference that the other end is installed on the picture circle leg 4.
