Description

The link-type compasses

Technical field

The utility model relates to compasses.

Background technology

Existing compasses are no matter be utilization centre slice, gear or other modes, and its structure mainly all is made up of compasses head and stitch and plumbous pin.As shown in Figure 5, this compasses 1 upper end is formed with a compasses head 10, and respectively a hinged stitch 11 and a plumbous pin 12, adjusts between the two distance by pulling stitch 11 and plumbous pin 12.Pen core folder 13 is inserted in these lead pin 12 bottoms, it runs through by a bolt 14 and utilizes nut 140 spiral shell fixed bits, be positioned at pen core and press from both sides 13 bottoms and then be provided with pen core 130, protrude out the pilot pin 110 of the usefulness that is useful on the location in stitch 11 bottoms, in addition this compasses head top and be provided with one handle 101.During use, adjust earlier drawn radius of a circle, then with pilot pin 110 centerings point, turning handle 101 makes plumbous pin 12 along with moving in a circle, and utilizes pen core 130 that pen core the presss from both sides 13 bottoms required circular arc that draws.

Another existing compasses, not to utilize to pull open the opening angle that mode is adjusted stitch and plumbous pin, as shown in Figure 6, these compasses 2 are made up of compasses head 20 and stitch 21, plumbous pin 22 equally, difference is that

plumbous pin

22 and 21 of stitch pass through and has been horizontally set with a screw rod 23, and be provided with one in screw rod 23 central authorities and adjust gear 230, and screw rod 23 runs through stitch 21 and plumbous pin 22 places are with swivel nut 210 and 220.When wanting to change the opening angle of stitch 21 and plumbous pin 22, rotation is earlier adjusted gear 230 and is done clockwise or counterclockwise rotation.Because of the hand of spiral difference of screw rod 23 both sides, when rotating, can drive stitch 21 and plumbous pin 22 moves in or out synchronously, and reach the purpose of control opening angle with swivel nut 210,220.This angle is not allowed to be subject to collision or user and is changed because of carelessness before not rotating adjustment gear 230.In order to adjust the opening angle of stitch 21 and plumbous pin 22, the length of screw rod 23 should be that the longer the better, but the long more both sides of screw rod 23 protrude out too much, and the packing of compasses and collection are inconvenient, and overall appearance is also influenced.

Summary of the invention

The purpose of this utility model is to provide a kind of stable link-type compasses of adjusting.

The purpose of this utility model can realize like this, designs a kind of link-type compasses, comprises compasses head, plumbous pin and stitch, and the end of plumbous pin is provided with paintbrush device, and the end of stitch is provided with pilot pin; Be respectively equipped with an axle bed on described stitch and the plumbous pin, and connect a sheet respectively, the other end of axle sheet is connected a side of a piece, the diaxon sheet is connected to the both sides of a piece, form a linkage, this piece centre has screw, is provided with one and can be screwed into the axis of rotation that screw rotates, this axis of rotation is with clockwise or rotate counterclockwise direction, and the Control Shaft piece is done upper and lower motion.

That the utility model not only possesses is stable, adjust performance easily, and the design by connecting rod, can exempt the side-prominent drawback of compasses two, instant packed and collection.

The specific embodiment

The utility model will be further described below in conjunction with embodiment.

As shown in Figure 1 and Figure 2, a kind of link-type compasses comprise compasses head 30, plumbous pin 32 and stitch 31, and compasses head 30 is hinged with plumbous pin 32 and stitch 31, and the end of plumbous pin 32 is provided with paintbrush device, and the end of stitch 31 is provided with pilot pin; Be respectively equipped with an

axle bed

311 and 321 on described stitch 4 and the plumbous pin 3, and connect a sheet 5 respectively, the other end of axle sheet 5 is connected a side of a piece 4, diaxon sheet 5 is connected to the both sides of a piece 4, form a linkage, these piece 4 centre have screw 40, are provided with one and can be screwed into the axis of rotation 6 that screw 40 rotates, this axis of rotation 6 is with clockwise or rotate counterclockwise direction, and Control Shaft piece 4 is done upper and lower motion.

As shown in Figure 1, compasses 3 comprise compasses head 30, stitch 31, plumbous pin 32, compasses head 30 tops are arranged with sleeve 33 on the other hand, grip rotation in the time that painting and calligraphy can being supplied, for the motion mode of stitch 31 and plumbous pin 32 and axis of rotation 6, as shown in Figure 2, this stitch 31 and plumbous pin 32 are respectively equipped with

axle bed

311 and 321, described axle bed 311,321 has respectively for axle sheet 5 with axle piece 4 inserts the clip slot that is connected, and has through hole 323 on clip slot; The central authorities of axle piece 4 have screw 40.Both sides utilize lug to be formed with

clip slot
