Abstract

The utility model discloses an elastic pen which is composed of a pen pipe, a pen holder, a back seat and a plug, wherein, the pen holder and the back seat are elastically connected and the pen holder can betelescopic according to the strength of writing. If the pen holder is pressed by the plug after the elastic pen is used, the elastic pen can also be used as an ordinary pen.

Description

A kind of spring pen

The utility model belongs to articles for writing, relates to a kind of spring pen.

Existing pen and ball pen have a variety of, but which kind of pen no matter after its nib paper, can firmly not reclaim because of the people that writes.Like this, a lot of people are arranged, firmly press down when writing and nib is damaged because the dynamics of writing support is held badly.Particularly concerning the children that just learned to write, the dynamics of writing also needs oneself to grope, and others is bad to explain in words.

The purpose of this utility model is the defective that overcomes prior art, provides a kind of can the elephant to use the conventional pen, the pen that also can arbitrarily stretch with the people's that writes dynamics.

The utility model is achieved in that it has a shaft of a writing brush, and the upper end of the shaft of a writing brush is equipped with a back seat, and penholder passes back seat and is installed in the shaft of a writing brush, and penholder upper end is connected with back seat elasticity, also is processed with internal thread and by the plug that has been threaded on back seat.

Advantage of the present utility model is to resemble to be used the conventional pen, nib is changed with the people's that writes dynamics stretch, and dynamics that reminds people holds a pen and the dynamics that nib contacts with paper make and write merrily and lightheartedly, the service life of prolongation nib.

Fig. 1 is the structural representation of the utility model embodiment 1;

Fig. 2 is the structural representation of the utility model embodiment 2.

Describe in detail below in conjunction with accompanying drawing.

The utility model has a shaft of a writing brush 1, and there is internal thread the upper end of the shaft of a writing brush 1, and by the back seat 4 that has been threaded, there is a hole at the middle part of back seat 4, and a penholder 2 is arranged in the hole; Be set with a spring 3 on the top of penholder 2, the upper end of spring is connected with back seat, also is processed with internal thread on the top of back seat 4, and is connected with a plug 5 by internal thread.

Embodiment 2: as shown in Figure 2: by the back seat 4 that has been threaded, in back seat 4 lower ends a resilient spring leaf 3 is installed in the shaft of a writing brush 1 upper end, in the middle of the spring leaf 3 hole is arranged, penholder 2 passes spring leaf 3.In back seat 4 upper ends by the plug 5 that has been threaded.

During use, be example with structure shown in Figure 1, when being in position shown in Figure 1, if the dynamics of writing is excessive, surpass the elastic force of spring, penholder will be withdrawn, and points out the people that writes with this.If do not wish its retraction, then rotatable plug 5 makes it that penholder 2 is pushed down, and like this, even the dynamics of writing is big again, nib can not be withdrawn, and promptly resembles to use the conventional pen.

Claims

1, a kind of spring pen comprises the shaft of a writing brush, penholder, back seat and plug, it is characterized in that, is connected for elasticity between penholder and the back seat; The upper end of back seat is by the plug that has been threaded.
