Description

pen with adjustable barrel length

technical field

The utility model relates to a tool for writing, in particular to a pen whose length can be adjusted at will. the

Background technique:

A pen is a tool for writing or drawing, through which colored solid or liquid ink is drawn on paper or other solid surfaces to draw symbols or pictures. At present, the length of the pens on the market is fixed, and the length of the pen holder cannot be adjusted, which sometimes leads to the phenomenon that it is not convenient to carry, and it is easy to break when placed in a pocket or other places, which brings great trouble to carrying.

Utility model content

The purpose of the utility model is to provide people with a pen with arbitrarily adjustable length of the pen in view of the defects and deficiencies of the above-mentioned prior art. the

In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: the pen with adjustable length of the pen holder, which includes a pen holder, a pen core placed in the pen holder, a pen cap buckled on the upper end of the pen holder, a nib arranged at the lower end of the pen holder and The pen cap is set on the outside of the pen head, and the inside of the pen holder is equipped with an extension pen holder, the extension pen holder is located above the pen core, and two symmetrical limit blocks are arranged at the bottom of the extension pen holder, between which there is a The spring, the side wall of the pen holder is provided with a plurality of small holes for accommodating limit blocks. By adjusting the expansion and contraction of the extension pen holder, the length of the pen holder can be adjusted. It is easy to carry when the pen holder is retracted, and it is convenient to write when the pen holder is extended. The length of the pen holder can be adjusted according to the needs. The capacity of the spiral ink tube is that of an ordinary refill. Twice, thus ensuring the service life of the pen, with the advantages of simple structure and convenient use. the

As a preference, a secondary penholder is arranged inside the extended penholder, two symmetrical secondary limit blocks are arranged at the bottom of the secondary penholder, and a secondary spring is installed between the two secondary limit blocks, so The side wall of the extended pen holder is provided with a plurality of secondary small holes for accommodating the secondary limiting blocks. Further improving the adjustment size range of the pen holder can make the length of the pen holder shorter when not in use, which is more conducive to safe carrying and will not be broken. the

As a preference, the said pen core is provided with a helical ink tube communicating with the pen tip to enhance the ink capacity. The capacity of the spiral ink tube is twice that of ordinary refills, which ensures the service life of the pen to a greater extent. the

As a preference, the inner wall of the pen holder is provided with a chute for the extended pen holder to slide up and down, and the chute is provided with a limiting hole for limiting the positioning of the extended pen holder to be pulled up and retracted in place. Bit blocks match. Better realize the positioning effect when the extended pen holder is pulled up and retracted in place. the

The beneficial effects of the utility model are: the length of the penholder is adjustable, it is easy to carry when the penholder shrinks, and it is convenient to write when the penholder is stretched out, and the length of the penholder can be adjusted according to needs, and the capacity of the spiral ink tube is that of an ordinary pen core. Twice, thus ensuring the service life of the pen, with the advantages of simple structure and convenient use. the

Detailed ways

As shown in Figure 1 and Figure 2, the utility model is a pen with adjustable length of the pen holder, which includes a pen holder 9, a refill 10 placed in the pen holder 9, a pen cap 1 buckled on the upper end of the pen holder 9, and is arranged on The nib 11 at the lower end of the pen holder 9 and the pen cap 12 sleeved on the outside of the nib 11 . The pen core 10 is provided with a helical ink tube 8 communicating with the nib 11 to enhance the ink capacity. The capacity of the helical ink tube 8 is twice that of a common pen core, thus ensuring the service life of the pen. The inner side of the described penholder 9 is provided with an extension penholder 5, which is located above the refill 10, and two symmetrical stoppers 7 are arranged at the bottom of the extension penholder 5, between which two stoppers 7 are installed. The spring 6 and the side wall of the pen holder 9 are provided with a plurality of small holes for accommodating the limit block 7 . The inner wall of the pen holder 9 is provided with a chute for the extension pen holder 5 to slide up and down, and the chute is provided with a limiting hole that limits the positioning and extension of the pen holder 5 to pull up and shrink in place. Bit block 7 fits. The second-level penholder 2 can also be set in the extended penholder 5, and two symmetrical second-level limit blocks 4 are arranged at the bottom of the second-level penholder 2, and a second-level limit block 4 is installed between the two second-level limit blocks 4 The spring 3 and the side wall of the extended pen holder 5 are provided with a plurality of secondary small holes for accommodating the secondary limit block 4 . Therefore, pulling the pen cover 1 can pull out the extension pen holder 5 or the secondary pen holder 2, so that the pen holder 9 becomes longer, thereby facilitating writing. When it needs to be carried, the extended penholder 5 and the secondary penholder 2 are inserted into the penholder 9, and the penholder 9 becomes shorter, which is convenient for carrying. the
