In other words, in the case where the first engaging hole 220 is formed on both sides of the first engaging hole 220, the position where the engager 100 is engaged can be varied, and if necessary, May be combined in pairs.

A first fixing knob 230 is horizontally coupled to one side surface of the center member 200 to fix and separate the magnetic member 100.

The first fixing knob 230 is coupled to one side of the center member 200 in a threaded manner by a connecting shaft projecting horizontally from one side in the axial direction so as to press one side of the arm 100.

Here, the first fixing knob 230 can be applied as a circular plate whose axial direction is horizontally positioned so as to be held by a user, but the shape of the first fixing knob 230 can be variously applied It is possible.

For example, the first fixing knob 230 may be formed with a plurality of anti-slip grooves (not shown) along the circumferential direction to prevent slippage.

When the first fixing knob 230 is rotated in the locking direction, the first fixing knob 230 presses and fixes one surface of the first fixing knob 230 while the connection shaft protruding from one surface in the axial direction is inserted into the center member.

On the other hand, when the first fixing knob 230 is rotated in the unlocking direction, the connecting shaft is retracted in a direction opposite to the center member 200, and is separated from one surface of the arm 100.

The seat member 240 is seated on the upper surface of the object to be cut 10, and the lower end of the center member is horizontally rotatably coupled to the upper end of the seat member 240.

Further, a plurality of support legs 241 may be formed at the lower end of the seating member 240 so as to be seated on the upper surface of the object 10 without shaking.

The support legs 241 are spaced along the lower edge of the seat member 240 and the lower ends of the support legs 241 extend downward to be seated on the cutting object 10.

In addition, the upper end of the center member 200 extends to a predetermined length, and a cylindrical gripping tube 250 is rotatably coupled to the outer side of the center member 200.

Since the center member 200 and the gripping tube 250 have a cylindrical shape corresponding to each other, the user can rotate the centering member 200 while holding the gripping tube 250 with one hand.

In addition, the lever 260 is further coupled to the upper end of the center member 200 so as to rotate horizontally with respect to the gripping tube 250.

The lever 260 is horizontally long and one longitudinal end of the lever 260 can be coupled to the upper end of the center member 200.

When the user rotates the lever 260 while holding the gripping tube 250 with one hand, the rotating member 200 and the person 100 coupled thereto rotate horizontally together with the lever 260 do.

At this time, the seating member 240 supports the lower portion of the rotary member 200 in a state of being placed on the cutting target 10 without shaking.

At least one bearing (270) is further coupled between the center member (200) and the gripper pipe (250).

The bearing 270 may be coupled between the lower end of the center member 300 and the seating member 240 and between the upper end of the center member 200 and the upper end of the gripper tube 250, respectively.

That is, the center member 200 can be easily rotated by the bearing 270 with respect to the seating member 240 and the gripping tube 250.

The socket 300 is installed movably along the longitudinal direction of the magnet 100. The socket 300 includes a body 310, an elevating member 320, and an elastic member 330.

The body 310 has a hollow 311 formed therein and a second engagement hole 312 is formed horizontally on one side of the body 310 so that the arm 100 is inserted into the hollow .

A pencil shim 30 for cutting a pattern or a cutting blade 20 for cutting a cutting object 10 is selectively coupled to the lower end of the body 310. [

A horizontal hole 313 is horizontally formed on the front surface of the body 310 and a vertical hole 314 extending downward from one end of the horizontal hole 313 is vertically formed.

The horizontal hole 313 forms a space in which the latching protrusion 321 is slid horizontally after the latching protrusion 321 is raised and the vertical hole 314 forms a space in which the latching protrusion 321, do.

A seating recess 313a is formed in the lower end of the horizontal hole 313 so as to allow a locking protrusion 321 to be described later to be seated in the recess 313. The seating recess 313a includes a locking protrusion 321 Do not change position by external force when seating.

The elevating member 320 is coupled to the hollow 311 of the body 310 to be elevatable and the cutting blade 20 or the pencil shim 30 is selectively coupled to the lower end of the elevating member 320.

To this end, a groove into which the upper end of the cutting blade 20 or the pencil shim 30 can be inserted is formed at the lower end of the lifting member 320 in a corresponding manner.

On one side of the elevating member 320, a locking protrusion 321 is horizontally protruded so that the user can lift the elevating member 320.

The locking protrusion 321 protrudes outward through the horizontal hole 313 and the vertical hole 314 so that the user can grasp it by hand.

For example, when the user lowered the locking protrusion 321 to the lower end of the vertical hole 314, the lifting member 320 is kept in a lowered state.

At this time, the elevating member 320 is maintained in a lowered state by the compressive elastic force transmitted from the elastic member 330, which will be described later.

On the other hand, when the user lifts the locking protrusion 321 and places the locking protrusion 321 on the upper end of the horizontal hole 313 connected to the upper end of the vertical hole 314, the lifting member 320 maintains the raised state.

At this time, the elevating member 320 maintains the elevated state while overcoming the compressive elastic force of the elastic member 330, which will be described later.

That is, when the elevating member 320 is lowered, the lower end of the cutting blade 20 or the pencil shim 30 protrudes to the lower end of the body 310 and is switched to the use state.

On the other hand, when raising the elevating member 320, the lower end of the cutting blade 20 or the pencil padding 30 is inserted into the body 310 and is switched to the non-use state.

For example, when the pencil padding 30 is joined to the lower end of the lifting member 320, a sketch (original plate, donut, etc.) for cutting can be drawn on the upper surface of the cutting target 10.

Thereafter, when the cutting blade 20 is coupled to the lower end of the lifting member 320, the cutting object 10 can be cut while rotating the socket 300 along the sketch previously drawn.

The elastic member 330 is inserted between the upper portion of the hollow portion 311 of the body 310 and the upper end of the lifting member 320 so that a compressive force is applied between the upper portion of the hollow portion 311 and the upper end of the lifting member 320 A coil spring shape can be used.

A second fixing knob 340 is horizontally coupled to one side surface of the body 310. The second fixing knob 340 has a connecting shaft horizontally protruded from one axial surface of the body 310, Or on a top surface thereof in a threaded manner so as to press one side surface of the magnet 100.

Here, the second fixing knob 340 can be applied to a circular plate shape in which the axial direction is horizontally positioned so that the user can hold it by hand, but the shape of the second fixing knob 340 can be variously applied It is possible.

For example, the second fixing knob 340 may be formed with a plurality of anti-slip grooves (not shown) along the circumferential direction to prevent slippage.

The second fixing knob 340 presses and fixes one surface of the second fixing knob 340 while inserting the connection shaft projected from one axial surface of the second fixing knob 340 into the center member 200 when the first fixing knob 340 rotates in the locking direction.

On the contrary, when the second fixing knob 340 is rotated in the unlocking direction, the connecting shaft is retracted in a direction opposite to the center member 200, and is spaced from one surface of the arm 100.

A roller 315 is further coupled to the lower end of the body 310. The roller 315 is seated on the upper surface of the object 10 to be cut.

The roller 315 is rotated about the vertical rotation center C1 when the socket 300 is rotated with respect to the vertical rotation center C of the center member 200. [

That is, since the roller 315 rollably supports the lower end of the socket 300, the frictional force with the cutting target 10 can be reduced when the socket 300 moves.

The socket 300 may be coupled to at least one side of the magnet 100 with respect to the center member 200 or may be coupled to at least one side of the magnet 100.

For example, when one socket 300 is coupled to one side of the ruler 100 with respect to the center member 200, the cutting target 10 is cut into a disk shape using one cutting edge 20 .

In this case, when a plurality of sockets 300 are coupled to one side of the cutter 100 with respect to the center member 200, a plurality of cutting blades 20 moved along the same line are used to cut the cut target 10 Can be cut into donut form.

Alternatively, when the socket 300 is coupled to both sides of the ruler 100 with respect to the center member 200, and the sockets 300 are coupled to the corresponding positions, a plurality of cutting edges (20) can cut the object to be cut (10) into a disc shape.

At this time, when the socket 300 is coupled to both sides of the ruler 100 with respect to the center member 200, and the sockets 300 are coupled to different positions, a plurality of cutting edges (20) can cut the object to be cut (10) into a donut shape.

As a result, in the present invention, the length of the socket 300 is measured, and then the socket 300 can be rotated with respect to the vertical rotation center C1 to draw and cut the sketch, It is possible to perform various types of cutting by adjusting the number of cuts, so that it is possible to draw and cut a sketch by using a single mechanism, so that convenience of use can be ensured and the cutting object 10 can be cut in various forms .

The present invention can also selectively couple the pencil shim 30 or the cutting blade 20 to one socket 300 and can hide the cutting blade 20 or the pencil shim 30 when not in use Structure, it is possible to reduce the risk of a safety accident when the socket 300 is replaced or stored.

In addition, since the present invention can separate the magnet 100 from the center member 200 and the socket 300 when not in use, the volume of the compass can be reduced, and storage is easy.

In addition, according to the present invention, a socket having a long length 100 is used to connect a socket, thereby obtaining a disk or donut-shaped cut having a diameter larger than that of a conventional compass.

Although a specific embodiment of the compass according to the present invention has been described, it is apparent that various modifications can be made without departing from the scope of the present invention.

Therefore, the scope of the present invention should not be construed as being limited to the embodiments described, but should be determined by the scope of the appended claims as well as the scope of the following claims.

It is to be understood that the above-described embodiments are illustrative and non-restrictive in all aspects and that the scope of the present invention is indicated by the appended claims rather than the foregoing description, And all changes or modifications that come within the spirit and scope of the appended claims are intended to be embraced within their scope.
