Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIGS. 1 and 2, a pen 100 according to the present invention includes a pen case 10, a pen core 20, and a stretching device 30. The pen 100 is inserted into the pen case 20 through the extension device 30 or the length of the pen case 20 extended from the pen case 10 or the length of the pen case 20 inserted into the pen case 10. [ It is easy to use because you can adjust the length of the wire accurately.

The pen case 10 is a hollow case and accommodates the pen core 20 and the expansion and contraction device 30. The pen case 10 has a through hole 101 through which one end of the pen core 20 can be drawn or drawn. In the present embodiment, the pen case 10 is composed of a plurality of parts that can be disassembled.

A pen tip 201 is provided at one end of the pen core 20 for writing, and the other end of the pen core 20 is connected to the expanding / contracting device 30 in the opposite direction. And the nib 201 is exposed to the outside through the through-hole 101. In the present embodiment, for easy exchange of the pen core 20, the pen core 20 is detachably connected to the expansion device 30. The pen nib 201 is pulled out of the pen case 10 through the through hole 101 under the driving of the expansion device 30 or into the pen case 10 through the through hole 101 .

The expansion device 30 is fixed to the inside of the pen case 10 and connected to one end of the pen case 20 to drive the pen case 20 to rotate the pen case 10, (20).

3 to 5, the expansion device 30 according to the present invention includes a controller 301, a stepper motor 302, a speed reducing device 303, a screw shaft 304, a tube 305 and a movable rail (slip) 306.

The controller 301 is electrically connected to the stepper motor 302 and can send control signals to control the rotation direction and the rotation angle of the stepper motor 302. In the present embodiment, the control signal is a pulse signal.

The stepper motor 302 is fixed inside the pen case 10 and is connected to one end of the screw shaft 304 and drives the screw shaft 304 to rotate the screw shaft 304 Rotate. The stepper motor 302 is connected to one end of the screw shaft 304 through a speed reducing device 303 and the stepper motor 302 drives the speed reducing device 303 The decelerator 303 rotates. The speed reduction device 303 can lower the rotation speed of the stepper motor 302 and increase the torque of the stepper motor 302 and further increase the torque of the stepper motor 302 by interlocking the screw shaft 304, 304 rotate.

A screw thread 3041 is formed at one end of the screw shaft 304 that is spaced apart from the decelerator 303. One end of the tube 305 is mated with the screw thread 3041 A screw hole 3051 is formed. The tube 305 is covered with the screw thread 3041 of the screw shaft 304 through the screw hole 3051 so that the tube 305 and the screw shaft 304 are fixed. In the present embodiment, a receiving hole 3053 is formed in the other end of the tube 305 located opposite to the end where the screw hole 3051 is located, and is paired with the pen core 20, One end of the pen core 20 remote from the nib 201 is detachably accommodated in the receiving hole 3053.

The tube 305 moves along the movable rail 306. In the present embodiment, the movable rail 306 is at least one groove portion 1021 provided in the inner wall 102 of the pen case 10. The tube 305 is formed with at least one protrusion 3052 paired with the groove portion 1021. The protrusion 3052 is received in the groove portion 1021 and extends along the groove portion 1021 Move. In the present embodiment, the number of grooves 1021 and the number of protrusions 3052 are two in each case.

The stepper motor 302 drives the screw shaft 304 through the decelerator 303 so that when the screw shaft 304 is drawn or drawn through the screw hole 3051 of the tube 305, The screw shaft 304 interlocks with the tube 305 and the tube 305 is moved along the movable rail 306 in the direction of approaching the stepper motor 302 or in a direction away from the stepper motor 302 You can move. Accordingly, the screw shaft 304 interlocks the pen tip 201 of the pen core 20 so that the pen tip 201 is pulled out or drawn in from the pen case 10 through the through hole 101.

More specifically, in this embodiment, when the stepper motor 302 rotates in the counterclockwise direction, the speed reduction device 303 interlocks the screw shaft 304, and the screw shaft 304 rotates And enters the screw hole 3051. The screw shaft 304 interlocks with the tube 305 and moves in the direction of approaching the screw shaft 304 along the movable rail 306. The nib 201 of the pen stem 20 is moved And moves in a direction to approach the pen case 10. On the other hand, when the stepper motor 302 rotates in the clockwise direction, the speed reducing device 303 is pulled out from the screw hole 3051 by interlocking the screw shaft 304. At this time, the screw shaft 304 interlocks with the tube 305, the tube 305 moves in a direction away from the screw shaft 304, and the pin stem 20 is interlocked with the tube shaft 305, The pen tip 201 of the pen case 10 is pulled out of the pen case 10.

The controller 301 controls a rotation direction and a rotation angle of the stepper motor 302 through a control signal and controls the rotation of the screw shaft 304 drawn or drawn in the screw hole 3051, The length of the pen shaft 20 drawn out or drawn from the pen case 10 is controlled by controlling the length of the pen shaft 10 (e.g., the moving direction and the moving distance of the screw shaft 305 in the movable rail 306). More specifically, in the present embodiment, the controller 301 sends out a pulse signal to ablate the stepper motor 302 at a predetermined angle in the counterclockwise or clockwise direction. Therefore, the screw shaft 304 is driven, and the screw shaft 304 can be pulled out or drawn in accordance with a predetermined number of threads of the screw hole 3051. In addition, the tube 305 can be interlocked and moved up and down by a predetermined distance from the movable rail 306, and can be adjusted to a predetermined length of the pen core 20 drawn or drawn in from the pen case 10 have.

In another embodiment, the speed reducing device 303 may be omitted. At this time, one end of the screw shaft 301 is directly connected to the stepper motor 302.

The expansion device 30 according to the present invention switches the power of the stepper motor 302 to the linear motion of the tub 305 and the pen 100 having the expansion device 30 is rotated by the stepper motor 302 The length of the pen core 20 drawn or drawn from the pen case 10 can be precisely controlled through the rotation speed and the rotation angle of the pen case 10. The expansion device 30 is small in volume, small in noise during use, and easy to use.
