Abstract
Foldable compasses belong to study supplies and mainly solve the problem that normal compasses are inconvenient to carry as pinpoints are exposed outside. The foldable compasses comprise a rotary shank and supporting legs, a fixed supporting leg is connected below the rotary shank, and a lead is fixed to the bottom end of the fixed supporting leg. The foldable compasses are characterized in that the fixed supporting leg with two sides open is designed hollow, one end of a movable supporting leg penetrates through the inside of the fixed supporting leg to be connected with the fixed supporting leg through a fastening knob, the middle of the movable supporting leg is provided with a transverse hollow groove, and a pinhead is mounted at the other end of the movable supporting leg through a fastening knob. The movable supporting leg can be folded into the hollow of the fixed supporting leg after the foldable compasses are not used, and the pinhead is not exposed, so that the foldable compasses are safe and convenient to carry.
Description
Technical field
The utility model relates to a kind of compasses, specifically a kind of folding compasses.
Background technology
Compasses are the stationery that people often use when drawing, and convenience is provided when drawing circle for people, but compasses have a shortcoming, exactly since needle point expose, dangerous when carrying.
The utility model content
The purpose of the utility model is to provide a kind of folding compasses, and these compasses can fold, convenience safe to carry.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of folding compasses, comprise handler and supporting leg, and described handler below connects fixed supporting leg; The fixed supporting leg bottom is fixed with pen core, it is characterized in that, described fixed supporting leg is a hollow design; Both-side opening, movable supporting legs one end passes from fixed supporting leg inside, and is connected with fixed supporting leg through tightening knob; A horizontal groove is established at the movable supporting legs middle part, and the other end of movable supporting legs is installed a syringe needle through tightening knob.
The beneficial effect of the utility model is: these folding compasses can fold movable leg in fixed supporting leg into hollow after using, and syringe needle does not expose, convenience safe to carry.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 handler, 2 movable supporting legs, 3 fixed supporting legs, 4 tightening knobs, 5 syringe needles.
The specific embodiment
As shown in Figure 1.A kind of folding compasses comprise handler 1 and supporting leg, and described handler 1 below connects fixed supporting leg 3; Fixed supporting leg 3 bottoms are fixed with pen core, and described fixed supporting leg 3 is a hollow design, both-side opening; Movable supporting legs 2 one ends pass from fixed supporting leg 3 inside, and are connected with fixed supporting leg 3 through tightening knob 4, and a horizontal groove is established at movable supporting legs 2 middle parts; Tightening knob 4 can slide in groove, and the other end of movable supporting legs 2 is installed a syringe needle 5 through tightening knob 4, when tightening knob 4 is unscrewed; Syringe needle 5 and movable supporting legs 2 all can take up solid knob 4 rotations between movable supporting legs 2 and the fixed supporting leg 3.
Should fold compasses in use, and can through tightening knob 4 movable supporting legs 2 laterally slided in fixed supporting leg 3 according to the size of drawn circle, to regulate the distance between needle point and the pen core; After using up, tightening knob 4 is unscrewed, syringe needle 5 is revolved to turn 90 degrees with movable supporting legs 2 tightening knob 4 is tightened after overlapping, movable supporting legs 2 is folded in fixed supporting leg 3 into hollow again, tighten tightening knob 4, syringe needle does not expose, convenience safe to carry.
