With this design, the user can further adjust the suitable hand position according to his own use habits, the posture of holding the pen or the angle of cutting, so that the user can perform the cutting work more comfortably. If you use it for a long time, you can also avoid the hand posture caused by the fixed posture and position by continuously adjusting the holding posture. Make damage. In addition, the grip can also be enhanced by different materials.

The present inventors also provide a technical feature as follows: A pen-type cutting device as described above, wherein the cutting assembly and the pen holder are designed to exhibit an inclination angle of less than 90 degrees. It can be seen from the general grip posture that the pen end usually presents a tilt angle with the writing paper. Therefore, the author also considers that when the user uses the artificial hand-held cutter, the tilt angle of the technical feature can help the user to normally hold the pen posture. The cutting end of the cutting assembly is perpendicular or nearly perpendicular to the cutting object, allowing the user to apply force to maximize the transmission to the cutting object, which is more labor-saving and comfortable. And the end of the cutting assembly can be a fixed or replaceable wheel cutter, designed by a wheel cutter.

The creator also provides a technical feature as follows: As with the pen-type cutting device described above, the cutting assembly end can be a replaceable cutting member. With this technical feature, when the cutting member is worn due to long use time or improper use, the cutting member can be easily replaced to extend the service life of the creation.

The cutting member of the foregoing technical features may be a general blade or a round knife. If the cutting member is a wheel cutter, its wheel design allows the user to use the pen-type cutting device of the creation to cut the pen, and the pen will be smoother, and when the cutting direction is changed, it is easier to match the cutting direction. .

It can be seen from the above technical means that the present invention can indeed improve the problems existing in the prior art and provide a pen-type cutting device which is more comfortable and convenient to use.
