An ink-type pointer is provided, including a housing, a circuit unit, a pen and ink writing module, and an electromagnetic unit. The housing includes an end opening and an accommodation space. The end opening is in communication with the accommodation space. The circuit unit is disposed inside the accommodation space. The pen and ink writing module is disposed inside the accommodation space, and includes a cartridge, a nib, and liquid ink. The cartridge includes a chamber, the nib is connected to the cartridge and extends out of the end opening, and the liquid ink is accommodated in the cartridge and is output through the nib. The electromagnetic unit is disposed inside the accommodation space and includes a magnet and a coil. The magnet includes a through hole, the coil is wound round the magnet and is electrically connected to the circuit unit, and the cartridge passes through the through hole.

The writing instrument comprises a first barrel, a second barrel, and a self-blocking assembly system for assembling the first barrel with the second barrel. The self-blocking assembly system includes a blocking device for blocking the first barrel with respect to the second barrel in a longitudinal direction and a locking device for locking the blocking device. The locking device includes a slot formed in the first barrel and two ramps carried by the second barrel. The slot extends in the longitudinal direction and has two longitudinal edges. The two ramps are configured to part the two longitudinal edges of the slot progressively in a circumferential direction as the first and second barrels are assembled. A window extends in the longitudinal direction formed between the two ramps, and a lateral button is housed at least partially in the window that includes guide surfaces for guiding the lateral button.

A writing, drawing, marking and/or painting utensil or cosmetics implement or input device for contact-sensitive surfaces, wherein the utensil/implement/device includes at least one shank element made of plastics material or a plastics-containing wood substitute. The at least one shank element has a surface, or in that the at least one shank element has a surface which is sheathed in a material layer having a cover surface. The surface of the shank element or the cover surface of the material layer is in the form of a haptic and/or non-slip layer. The haptic and/or non-slip layer has a structure formed in one piece with the shank element and/or the material layer. The structure is formed by corrugation.

The present invention discloses a novel soft collet including a gripping part made of an elastic material and a connection part. The gripping part includes at least two fingertips matched with each other for gripping. A finger gap is formed between the fingertips, and a finger cavity is arranged inside each fingertip. The connection part includes a communication chamber which is communicating with each finger cavity. The connection part is provided with a communication port communicating with the communication chamber. The fingertip includes an inner wall close to the finger gap and an outer wall remote from the finger gap. The thickness of the inner wall is smaller than that of the outer wall, or the elastic modulus of the inner wall is smaller than that of the outer wall.

A writing instrument assembly has a writing instrument with a body and a working tip extended or extendable from the body. A holder has a landing spot for the writing instrument. The writing instrument is magnetically and detachably retained at the landing spot when attached to the holder. The working tip is sheathed or covered automatically when the writing instrument is attached to the holder and is unsheathed or uncovered when detached from the holder.

Provided is an aqueous ink composition for a writing instrument which is excellent in a drying property of drawn lines and a low temperature stability of the ink while inhibiting the pen tip from drying and which prevents the drawn lines from causing feathering and strike-through. The aqueous ink composition for a writing instrument described above contains at least a colorant, trimethylglycine, pentaerythritol, 10% by mass or less of a water-soluble organic solvent and water.

The anti-stress pen is designed in a way that its body is divided into two equal parts or proportional to the hand in two unequal parts and is capable of stimulating the nerves of the palm. By moving the pocket head clamp downwards, the lower part of the pen body, which has a small tooth, is moved by transfer and rotation. The pen is designed focusing on a population of pen users who are accustomed to playing with the pen body. The nerves in the fleshy part of the palm were considered. When we work with the pen pocket head clamp, the lower part of it massages the palm. Scientifically, the palmar nerves are related to digestive glands which reduce stress; then, by producing the pen, we can improve digestive function and reduce stress via stimulating the nerves.
