Abstract

The utility model belongs to the category of cultural goods, comprising a penholder made of a strip sheet by twisting crinkling and finalizing with a certain tenacity, intension and wear resistance. The utility model is deployed with a pen cap with a massage healthy function, so as the practical popularized pen with a flex length, an entering penholder, and has multiple functions of massaging and eliminating mind tire.

Description

The folding pen of spiral elastic force

The utility model belongs to stationery category, is a kind ofly to carry out helical form by sheeting and curl after the typing, has certain longitudinal elasticity and folding pen.

At present, also there is not a kind of penholder of popular style can be adjusted to the 5CM length of pocket or practical 15CM length easily on the market; The stronger vertical elastic force that self just has that does not also have a kind of penholder; If it is 15CM that a kind of pen length is in use arranged, and the length when carrying can be shrunk to 5CM, but and have penholder typing and elastic massaging health-care effect, will bring the function that greatly facilitates and overflow to use to the user so undoubtedly.

The purpose of this utility model be exactly make a kind of with material with low cost, but possess and have that length is scalable, the penholder typing by the helical form typing of curling, have the popular multipurpose pen of health care massage effect simultaneously.

The purpose of this utility model is achieved in that selects a kind of strip sheet material with better toughness, wearability, prints some text informations commonly used (as English word, mathematical formulae etc., or being printed as the address list form) thereon; Mode by the typing of curling makes sheet material become helical form, is equipped with special-purpose nib and the pen core and the pen cap, can become the multi-purpose folding pen with above-mentioned every function so.Its function is achieved in that because penholder is to be curled and curl by the sheet material of strip, and the write down area of sheet material is about more than 40 times of cylindrical penholder area, therefore can be used for practical typing fully; Simultaneously, owing to be to be rolled into helical form with the stronger sheet material of toughness, the tired operation principle that is similar to spring, therefore its structure be not only contractile, and in compression, the power of generation when be out of shape by the sheet material transmission, be rotated and push and promote the end, be equipped with the pen cap configuration design of semicircle bud shape again, can become a kind of utensil of therapeutic massage easily, benefit study and work mental relaxation afterwards.

In sum, owing to adopted spiral helicine sheet structure penholder, but make common lettering pen have that length is collapsible, the penholder typing, and have the multiple use of elastic massaging health-care effect.

The utility model is described in further detail below in conjunction with accompanying drawing:

The expansion profile of Fig. 1 strip sheet material (being reduced into 1/3)

The profile of Fig. 2 strip sheet material after the typing of curling

Fig. 3 the utility model profile in use

Profile when Fig. 4 the utility model carries

But the semicircle bud shape on the small column 6 that is used on the aperture 3 that is used on the typing position 2 among the figure 1, on the strip sheet material, the sheet material being connected with nib, nib 4, pen core 5, the nib being connected with sheet material, the profile 7 when the helical form sheet material shrinks, the pen cap 8, the pen cap designs

Below be to realize one of mode of the present utility model: at first the selecting for use of penholder sheet material (Fig. 1), because that it need possess is wear-resisting, high tenacity, certain intensity is arranged, and cost is low, therefore selects the thick PVC sheet material of 0.1MM---0.2MM for use.The size of sheet material by practice and calculating, selects for use the long 4CM of 35CM wide by the appearance and size of conventional pen, and the plastic sheet that has printed is rolled into helical form (Fig. 2), and the typing of heating promptly becomes penholder; And matched nib (Fig. 3-3), because penholder need be fixed when shrinking placement, therefore its head is provided with a small column (Fig. 3-5), also is provided with a supporting small sircle hole (Fig. 1-2) in the end of penholder simultaneously.And the pen cap (Fig. 4-7) therefore is designed to semicircular bud shape (Fig. 4-8) owing to need be used for the rubbing use.

Claims (2)

1, a kind of folding lettering pen, being linked in sequence by pen core, nib, penholder forms, and it is characterized in that: pen core is positioned among the nib, and nib is fixedlyed connected with penholder.

2, folding lettering pen according to claim 1 is characterized in that: its penholder is made through the curling typing of helical form by the flaky material of strip.
