Abstract
A screw device is provided on a surface of one end of the screw shaft which is separated from the stepper motor, and a screw thread is provided on the surface of the one end of the screw shaft, Wherein one end of the tube is provided with a screw hole mating with the screw thread, the tube is connected to the screw shaft through the screw hole, the stepper motor drives the screw shaft, And the tube is moved in the direction of approaching or departing from the stepper motor.
Description
BACKGROUND OF THE INVENTION [0002] The present invention relates to a telescopic device, and more particularly to a pen having a telescopic device.
Depending on the changes in the surrounding environment, the pen tip preferably automatically withdraws from the pen case or enters the pen case. However, since the driving device installed in the conventional smart pen can not control the stretching length of the pen shim accurately, it is necessary to adjust the stretching length through the position restricting device. Therefore, the volume of the driving device is increased and the volume of the pen case is also increased. In addition, when the driving device is driven, a large vibration and a large noise are generated.
The present invention has been devised in view of the above points, and it is an object of the present invention to provide a stretching device which can precisely adjust an extension / contraction length of a pen shim, has a small volume and is small in vibration and noise at the time of use, .
According to an aspect of the present invention, there is provided an expansion device including a stepper motor, a screw shaft, and a tube, the stepper motor being connected to one end of the screw shaft, Wherein a threaded hole is provided at one end of the tube, and the tube is connected to the screw shaft through the screw hole, and the stepper motor drives the screw shaft So that the screw shaft can be pulled out or drawn out from the screw hole, and the tube moves in a direction approaching or moving away from the stepper motor.
In order to achieve the above object, the pen according to the present invention has a hollow pen case, a pen core accommodated in the pen case, and a stretching device. The pen case has a pen tip for writing, Wherein said stepper motor is connected to one end of said screw shaft and said stepper motor is connected to said one end of said screw shaft, Wherein a screw thread is provided on a surface of the one end of the screw shaft which is distant from the motor, and a screw hole paired with the screw thread is formed at one end of the tube, Wherein one end of the pen shim remote from the pen tip is detachably connected to one end of the tube, Emitter by driving the screw shaft and the screw shaft is pulled out or be drawn from the hole of the screw, the tube may be drawn out or drawn from the pen point is the pen case by moving according to the direction away from or close to the said stepper motor.
The expansion device according to the present invention and the pen having the expansion and contraction device can precisely adjust the length of the pen shim extended from the pen case or the length of the pen shim entered into the pen case, , And it is easy to use because vibration and noise are small during use.
