Technical Field

The invention relates to the field of stationery, in particular to a method for locking the distance between two feet of compasses.

Background

In order to overcome the technical problems, the distance between the two feet of the compass is usually maintained by directly controlling the feet of the compass in the prior art, most commonly, a pre-tightening force of the head of the compass is increased or threaded holes are formed in the two feet of the compass, and a limiting device such as a screw and the like for limiting the opening and closing of the two feet of the compass is additionally arranged, so that the two feet of the compass are not easily opened when the pre-tightening force is increased, the resistance of the two feet of the compass is large when the two feet of the compass are opened and closed, and the compass is very strenuous to use, and the mode of increasing the screw rod needs to rotate the screw rod to adjust when using, and the regulation is slower, and the operation is inconvenient.

Disclosure of Invention

In view of the above, the present invention aims to provide a method for locking the distance between two compasses feet, which is less likely to slide relative to each other during drawing, and is more labor-saving and convenient to operate.

In order to achieve the above purpose, the solution of the invention is:

a method for locking the distance between two feet of a compass is characterized by comprising the following steps:

the compasses comprise a compasses head, a handle, a mechanism and a pair of compasses feet, wherein the compasses head is connected with the handle in a linear sliding manner, the handle is connected with the two compasses feet of the compasses in a transmission manner through the mechanism, and the handle slides in the compasses head when the distance between the two compasses feet is changed.

And step two, after the distance between the two compasses feet is adjusted to the required distance, the handle and the compasses head are fixed together, and the handle and the compasses head are kept relatively immovable.

Further, the mechanism includes screw, center plate and card post, center plate and handle body coupling, the card post sets up on the compasses foot, the lamellar body of center plate for seting up the through-hole, the cross section of through-hole is the cross, the through-hole includes crossing transverse hole of mutually perpendicular and vertical hole, the slip of card post sets up in the transverse hole, the double-screw bolt of screw wears to locate one of them in proper order the compasses foot through-hole and another set up the compasses foot, the screw with vertical hole cooperatees, two the compasses foot with the screw rotates for the pivot.

Further, the head has a clamping means, and in the second step, the clamping means clamps the handle so as to keep the handle and the head relatively stationary.

Further, the compass head has a locking device, and in the second step, the locking device presses the handle against the compass head from one side in the width direction or one side in the thickness direction of the handle so as to keep the handle and the compass head relatively stationary.

Further, the method comprises the following steps: and the side surfaces of the two sides of the handle in the width direction or the side surfaces of the two sides of the handle in the thickness direction are provided with anti-skidding structures.

Furthermore, the anti-skid structure is a sawtooth structure arranged on two sides of the handle in the width direction.

Furthermore, the sawtooth structure comprises a plurality of sawtooth units with the same shape, and the sawtooth units are one of square sawtooth units, hook-shaped sawtooth units, arc-shaped sawtooth units and strip-shaped sawtooth units.

Furthermore, the sawtooth structure comprises a plurality of sawtooth units, and the sawtooth units are at least two of a square sawtooth unit, a hook-shaped sawtooth unit, an arc sawtooth unit and a strip sawtooth unit.

After the structure is adopted, the method for locking the distance between the two feet of the compasses has the following beneficial effects: when the distance between two compasses feet is adjusted to required distance, with the handle with the compasses head is together fixed, keep the handle with the compasses head is motionless relatively and then locks the distance between two compasses feet, and when breaking off the compasses both feet off with the fingers, the handle is not together fixed with the compasses head, and the handle slides at the compasses head internal straight line of compasses, consequently adjusts the compasses feet distance and receives the in-process two compasses feet of receipts and break off with the fingers easily, and is more laborsaving during the use, when adjusting the distance between the compasses feet, the handle does not receive the restriction, and the compasses foot can realize opening and shutting fast, fixes handle and compasses head when locking the compasses feet distance again, and it is more convenient to use.
