The compasses solve the problems that when the traditional compasses are used, people always use the ruler to fix the radius, the radius is fixed, the radius is required to be measured again due to the fact that the radius of a foot of the compasses is changed due to stress, a plurality of tools are needed to be matched during drawing, time is wasted, and efficiency is influenced.

Description

Multifunctional compasses

Technical Field

The utility model belongs to the technical field of the compasses, concretely relates to multifunctional compasses.

Background

Compasses are used for drawing circles or strings in mathematics and drawing, and are commonly used for drawing rulers and compasses. When the traditional compasses are used for drawing, the distance between two feet of the compasses is measured by a ruler to be used as the radius of a circle, then one end with a needle is fixed at one place to be used as the center of the circle, then one end with a pencil is rotated for one circle, and after the rotation is finished, one circle appears. When the traditional compasses are used, people always use the ruler to fix the radius, the radius is fixed, the radius change of the foot of the compasses caused by stress is frequently met, the radius needs to be measured again, and a plurality of tools are needed to be matched during drawing, so that the time is wasted, and the efficiency is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a multi-functional compasses, when solving and using traditional compasses, people always use the ruler to fix the radius earlier, fix the radius, often meet meeting the compasses foot and lead to the radius change because of the atress, and need measure the radius again, need a lot of instrument cooperations when mapping like this, waste time, the problem of efficiency of influence.

In order to solve the technical problem, the utility model discloses a technical scheme as follows:

the utility model provides a multifunctional compass, includes the mobile jib, the mobile jib top is connected with the handle, and mobile jib fixed connection main scale one end is located main scale top main scale bolted connection crossbeam one end, the main scale other end and head rod one end bolted connection, the crossbeam other end and head rod other end bolted connection are located sliding connection on the crossbeam and are had the crossbeam movable block, and sliding connection has the vernier on the main scale, and second connecting rod both ends are connected respectively to crossbeam movable block and vernier, the mobile jib bottom is connected with first measuring claw, and first measuring claw bottom is connected with the compasses steel needle, the vernier bottom is connected with the second and measures the claw, and the second is measured the claw bottom and is connected the pen core piece.

Preferably, knurling hand screwing bolts are arranged at the pen core block and the compass steel needle.

Preferably, the handle is provided with anti-skid lines.

Preferably, the main scale is provided with a scale.

Compared with the prior art, the utility model has the advantages of it is following:

the utility model discloses a multifunctional compass can be when rotating the compasses through being equipped with anti-skidding line, increases frictional force, stability when guaranteeing to rotate, through setting up second connecting rod fixed connection crossbeam movable block and vernier, can remove the vernier through removing the movable block, still be used for supporting beam and main scale, measure the claw through setting up first measurement claw and second, can be used for measuring the interior outer footpath of target, twist the bolt through being equipped with the annular knurl hand in refill piece and compasses steel needle department, mainly be used for fixed pen core piece and compasses steel needle.
