Abstract

The utility model discloses a pair of suction-disc-type multipurpose compasses, which consist of a handle, a main rod and an auxiliary rod. The main rod is provided with a suction-disc-type rotatable leg, a retractable positioning needle is arranged in a suction disc, the suction disc is connected onto the main rod through a rotatable part and the lower end of the positioning needle stretches out of the horizontal surface of the lower edge of the suction disc. By adopting the technical scheme, the suction-disc-type multipurpose compasses have the beneficial effects that since the lower end of the retractable positioning needle arranged below the suction disc stretches out of the horizontal surface of the lower edge of the suction disc, when the suction-disc-type multipurpose compasses are used, a circle center can be accurately positioned through the end of the positioning needle, then the suction disc is pressed downwards, the positioning needle is fully retracted till air in the suction disc is emptied, the suction disc is enabled to be stably adsorbed, operation can be started by using the compasses and the problem that the circle center cannot be accurately positioned by using the existing suction-disc-type is overcome.

Description

A kind of sucker type multipurpose way compasses

Technical field

The utility model relates to be write or the compasses in drawing appliance field, particularly as the sucked type compasses of stationery and instrument.

Background technology

Industry instruments commonly used such as compasses are that the student fulfils assignment, teachers ' teaching and building, finishing, traditional compasses are tip because of two legs, are very easy on planes such as paper, blackboard, wall, glass plate, skid, and are difficult for fixing.Occurred the sucked type compasses in recent years, but because the one of which leg is a sucker, the center of circle is difficult to confirm, cause when needing accurately to confirm the center of circle to be difficult to accomplish, and also there is the problem that turns to inconvenience easily in connecting portion.Like the patent No. is 02211888.8 sucker compass, and its sucker pin is installed in the center-pole lower position, constitutes lampshade shape overall structure, and function has been anti-skidding effect; Bolt I is installed in the centre position of body, plays fixation; Rotating shaft is installed in the centre position of center-pole, constitutes microscler shape overall structure, and function is the action usefulness that runs up.But its sucker pin is a lampshade shape, is difficult to accurately locate the center of circle, and this rotating shaft is the elongate in shape overall structure, has the problem of rotating inconvenience.Also all there is this type problem in utility model patent like the patent No. 01223552.0 in addition.

The utility model content

The purpose of the utility model provides a kind of sucker type multipurpose way compasses; These sucker type multipurpose way compasses can stably be drawn a picture at smooth surface; Convenient again definite center of circle; And can unhinderedly rotate, can also assemble with multiple instrument, can be widely used as student stationery, teacher's teaching aid, glass partition tools etc.

The technical scheme of the utility model is achieved in that a kind of sucker type multipurpose way compasses; Form by handle, mobile jib and secondary bar; Said mobile jib has the rotatable pin of sucked type, and promptly sucker is provided with telescopic pilot pin in the sucker; Sucker is connected on the mobile jib through rotatable components, and the lower edge horizontal plane of said sucker is stretched out in the lower end of said pilot pin.

Preferably; Said pilot pin comprises the hollow retracting cylinder of location division that a lower end end is a needle-like and the sealing of at least one joint upper end; Said retracting cylinder slides successively from top to bottom and is nested in the cavity of a joint; All being equiped with spring in the said cavity, slides and is nested in said retracting cylinder in the cavity of below one joint in the upper end of said location division, and the retracting cylinder of said the top is embedded on the said sucker.

Preferably, the rotatable components of said connection sucker and mobile jib is a spheroid shaft coupling.

Preferably, the rotatable components between said mobile jib and the sucker is to be sheathed on the axle sleeve that in the rotating shaft of being located at said sucker top, also can horizontally rotate, and said mobile jib and said axle sleeve are hinged.

Preferably, said secondary bar lower end is equiped with anchor clamps, removable pencil, chalk, icking tool or the diamond cutter of being equiped with on the said anchor clamps.

The beneficial effect of present technique scheme is, stretches out the lower edge horizontal plane of said sucker through the lower end that telescopic pilot pin is set under sucker, in use; Can accurately locate the center of circle with the end of pilot pin, then with sucker to pressing down, pilot pin all is withdrawn into; Up to the inner air emptying of sucker; Make stable the adsorbing of sucker, can bring into use the compasses operation then, overcome the problem that existing sucked type compasses can not accurately be located the center of circle.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition that after the content of having read the utility model those skilled in the art can do various changes or modification to the utility model, these equivalent form of values fall within the attached claims restricted portion of the application equally.

Embodiment 1

As depicted in figs. 1 and 2; A kind of sucker type multipurpose way compasses are made up of handle 1, mobile jib 2 and secondary bar 3, and said mobile jib 2 has the rotatable pin of sucked type; It is sucker 22; Be provided with telescopic pilot pin 4 in the sucker 22, sucker 22 is connected on the mobile jib 2 through rotatable components 21, and the lower edge horizontal plane of said sucker 22 is stretched out in the lower end of said pilot pin 4.

Said pilot pin 4 comprises the hollow retracting cylinder 41 of location division 42 that a lower end end is a needle-like and three joint upper end sealings; Said retracting cylinder 41 slides successively from top to bottom and is nested in the cavity of a joint; All be equiped with spring 43 in the said cavity; Slide and be nested in said retracting cylinder 41 in the cavity of below one joint in the upper end of said location division 42, the retracting cylinder 41 of said the top is embedded on the said sucker 22.The rotatable components 21 that connects sucker 22 and mobile jib 2 is spheroid shaft couplings.
