A multi-purpose combination writing instrument is provided. The instrument can comprise a writing instrument holder, with 2 casing members connected together by a retractable unwinding tool. The retractable unwinding tool can be automatically retractable. One or more removable individual writing instruments can be reversibly attached to the writing instrument holder. An individual writing instrument is provided that comprises a male connector adapted to be mated to a corresponding female connector or that comprises an external screw thread. A casing member of a writing instrument holder is provided, comprising an automatic retracting mechanism stored in the casing member and adapted to be attached to a retractable unwinding tool and adapted to allow the retractable unwinding tool to automatically retract. Another multi-purpose combination writing instrument is provided, comprising a writing instrument holder that is fan-shaped (like a hand-held fan). Yet another multi-purpose combination writing instrument is provided, comprising a writing instrument holder comprising zero, one, or two casing members comprising a hinge assembly, which comprises a hinge.

The present invention relates to a lift-pull pen, which includes a pen point tube, an outer tube, a refill and a return spring. The pen point tube and the outer tube are nested to form an outer pen shell. The refill is located in the outer pen shell. The return spring is located in the pen point tube and specifically located between a pen point end of the refill and the pen point tube. The pen point tube extends to be provided with one or a plurality of buckle extension bodies and one or a plurality of fixed extension columns extend from the pen point tube.

A stylus suitable for an electronic device is provided. The stylus comprises a pen barrel and a pen core. The pen barrel has a sidewall and at least one first protrusion, and the first protrusion is located at an inner side of the sidewall. The pen core movably passes through the pen barrel. The pen core has a pen tip and at least one second protrusion. Under a first status, the first protrusion and the second protrusion are dislocated from each other. Under a second status, the first protrusion and the second protrusion are aligned with each other to make a part of pen barrel expand and deform.

A writing instrument extending between a first end and a second end, the writing instrument including a writing element, a first housing member extending between the first end and the second end and oriented about at least a portion of the writing element, and a second housing member extending between the first end and the second end and oriented about at least a portion of the first housing member, the second housing member being configured to move relative to the first housing member, between a first relative position and a second relative position, and at least a portion of the second housing member being configured to move radially with respect to the first housing member, wherein the relative movement of the second housing member automatically transitions the writing instrument from a writing state toward a non-writing state.

A writing instrument may include an elongated tubular casing, an elongated writing medium cartridge and a tubular elastic spring element. The tubular elastic spring element comprises a first portion and a second portion. The second portion comprises a wall comprising a plurality of apertures.

A writing instrument includes a body, a nosecone, and an adaptor each being of generally hollow tubular shape. The body, the nosecone, and the adaptor each have a first end and a second end. The first end of the adaptor is configured to slidably couple to the nosecone second end. The second end of the adaptor is coupled to the first end of the body. The writing instrument includes a writing element with a mounting end and a writing end where the mounting end is removably coupled to the second end of the body. The writing instrument includes a locking mechanism configured to selectively lock the nosecone in a storage position or a writing position. In the storage position, the nosecone extends and covers the writing end. In the writing position, the nosecone retracts and the writing end of the writing element extends beyond the nosecone.

A writing instrument for alternating between an active stylus tip and an ink pen tip which is retractable from and displaceable through an annular opening at one end of the writing instrument.
