Description

 Elastic hard pen with adjustable elastic strength

 The present invention relates to an elastic hard pen that can adjust elastic strength.

Background technique

 At present, the elastic hard pen is made of an elastic material such as rubber or wire spring from the end of the pen tip to the finger holding portion of the pen (see the patent number of 98216642. 7 invented by Xu Genhua). Smooth elastic pen"), but the elastic pen can write more smoothly, the font is more beautiful, and the fatigue of writing is reduced. The elastic strength of the pen is exactly matched with the writing strength of the user. Otherwise, it is too hard. When the ordinary hard pen is used, it is too soft, and the writing stroke is inaccurate, difficult to control, and even difficult to write. The elastic strength of the pen that matches the writing strength of the user is different from person to person, and one kind of elastic hard pen, The elastic strength of the pen may be just right for some people, but it may be too hard for some people, but too soft for some people. At the same time, the same user's requirements for the elastic strength of the pen under different writing conditions will be different. Even sometimes, an elastic hard pen is required to be converted into a normal hard pen with no elasticity of the pen. Therefore, at this time, the elastic pen with a single elastic strength cannot satisfy the different requirements of the elastic strength of the pen under different writing conditions by different users or the same user, and a flexible pen suitable for the writing strength is needed. Summary of the invention

 SUMMARY OF THE INVENTION It is an object of the present invention to provide an elastic hard pen which can adjust the elastic strength, which can meet the different requirements of different users or the same user for the elastic strength of the pen under different writing conditions.

The technical content of the invention comprises: a pen holder having a length of elastic body, the pen holder is internally provided with an elastic refill, and the pen holder is also coupled to move in front and rear directions along the axis of the pen shaft to adjust The adjusting rod device for bending the working length of the elastic segment body.

 The invention has the beneficial effects that: the elastic strength of the elastic hard pen can be freely adjusted, and the elastic pen can be conveniently converted between the elastic hard pen and the pen with no elasticity, which can satisfy different users or the same user. Under the different writing conditions, the different requirements of the elastic strength of the pen are truly smoother, the font is more beautiful, and the writing fatigue is relieved.

detailed description

 Embodiment 1 of the present invention, as shown in FIG. 1, includes a pen holder 2 having a length of elastic body 1. The pen holder 2 is internally provided with an elastic refill 3, and the pen holder 2 is also coupled to move forward and backward along the axis of the pen axis. The adjusting rod device for adjusting the bending working length of the elastic segment body, the pen holder 2 is a hollow pen holder, and the inner wall of the rear portion of the pen holder is provided with an internal thread, and is connected with the external thread of the adjusting rod 4 through which the rear side opening penetrates, the working process: Rotating the adjusting rod causes the length of the front end of the adjusting rod to extend into the elastic body to change, and the bending working length of the elastic segment body also changes accordingly, and the elasticity of the pen piece changes. When the front end of the adjusting rod passes through the elastic body, the pen piece elastically disappears, thereby Real 3⁄43⁄4' adjusts the elastic strength of the elastic hard pen holder.

Embodiment 2 of the present invention, as shown in FIG. 2, includes a pen holder 2 having a length of elastic body 1. The pen holder 2 is internally provided with an elastic refill 3, and the pen holder 2 is also coupled to move forward and backward along the axis of the pen axis. The adjusting rod device for adjusting the bending working length of the elastic segment body, the outer circumference of the rear side portion of the pen holder 2 is provided with the anti-slip annular rib 5, and the adjusting rod 4 disposed around the periphery of the pen holder The inner wall is correspondingly provided with an annular recess 6 which is matched with the non-slip annular rib 5, and the working process: through the telescopic adjustment rod, the length of the elastic body is changed at the front end of the adjusting rod, and the bending working length of the elastic segment body is also followed. Correspondingly, the elasticity of the pen bar changes. When the front end of the adjusting rod passes through the elastic body, the elasticity of the pen bar disappears, thereby achieving the purpose of adjusting the elastic strength of the elastic hard pen pen.

 Embodiment 3 of the present invention, as shown in FIGS. 3 and 4, includes a pen holder 2 having a length of elastic body 1. The pen holder 2 is internally provided with an elastic refill 3, and the pen holder 2 is also coupled to the front and rear of the pen axis. An adjusting rod device for adjusting a bending working length of the elastic segment body, wherein the pen holder is a hollow pen holder, and the hollow pen holder body is provided with a sliding sleeve 7 which can slide along the axial direction of the axial line, and the outer peripheral wall of the sliding sleeve 7 is provided with a slide rail 9 parallel to the axis line, the inner peripheral wall of the hollow 'pen is correspondingly provided with a slide rail 8 embedded in the slide rail 9, and the inner wall of the sleeve 7 is provided with an internal thread and extends from the rear side opening of the hollow stem The external screw of the adjusting screw 12 is connected, and the adjusting screw 12 is supported by the bearing body 10 at the rear side of the hollow pen holder, and is axially positioned by the axial limiting recess 11 of the adjusting screw body. Working process: Rotating the adjusting screw, the adjusting screw limits the axial movement of the adjusting screw due to the axial limit of the limiting groove of the adjusting screw, adjusting the axial movement of the screw driving sliding sleeve, and the length of the sliding sleeve extending into the elastic body changes, the elastic segment body Qu working length also will be a corresponding change in the elastic sheath is changed, when the sleeve distal end run through the elastomer, elastic pen disappears, thus achieving the purpose of adjusting the elastic strength of the elastic sheath is Pen.

 The invention not only has the advantages of simple structure, stable and reliable operation, but also convenient adjustment and use, and can greatly reduce the writing fatigue of the user.
