The utility model discloses a hairpin pen which comprises a pen body and a hairpin. A connecting base extending in the length direction of the pen body is arranged at the end, away from a pen point, of the pen body. The hairpin comprises two hinged clamping plates, namely a first clamping plate and a second clamping plate, an elastic piece is arranged between the first clamping plate and the second clamping plate, and the elastic piece enables one ends of the two clamping plates to always have the movement tendency of relative clamping; the first clamping plate is detachably connected with the connecting base. The hairpin pen not only has a hairpin function, but also enables the hairpin to be convenient to wear, light in weight and not easy to fall off.

A partition plate dividing a cavity into an upper pen cavity and a lower pen cavity is arranged in a pen body, a fixing groove is formed in the outer side of the upper portion of the pen body, lens wiping cloth is fixed in the fixing groove, and a pen clip detachably connected to the outer end of the upper pen cavity is arranged at the top of the pen body. The pen further comprises a contained piece, a supporting piece arranged at one end of the contained piece and a pen point arranged at the other end of the contained piece, the contained piece is in interference connection with the outer end of the lower pen cavity, the supporting piece is located in the lower pen cavity, the pen point is located outside the pen body, the pen point is sleeved with a pen cap, and a touch control head is arranged at the outer end of the pen cap. The multifunctional pen container is novel in structural style, has multiple functions, and is wide in applicable occasion and diversified in purpose.

The invention relates to a pen, comprising a pen body (12) elongated in the direction of a pen longitudinal axis (L), on a first axial end region (18) of the pen body (12) a pen functional unit (20), on a second axial end region (24) of the pen body (12) a pen connection unit (34) exposed on an axial end face (42) of the pen body (12) for producing an electrical plug-in connection, and a clip unit (52) which can be releasably attached to the second axial end region (24) of the pen body (12) by axially plugging to the pen body (12) and has a clip body (46) and at least one fastening clip (52) extending from the clip body (46), wherein when the clip unit (26) is attached to the pen body (12), the pen connection unit (34) is covered by the clip body (26), and the at least one fastening clip (52) extends substantially in the direction of the pen longitudinal axis (L) along the pen body (12).

To provide a manufacturing method for producing a resin molding including a clip part of a writing instrument, capable of enhancing shape accuracy of the clip part.SOLUTION: The present invention relates to a manufacturing method for producing a resin molding including a clip part of a writing instrument, which uses a right side auxiliary member which constitutes a part of a cavity side inner surface defining a right side cavity of a right side mold and is capable of protruding and moving inward of the right side cavity, and a left side auxiliary member which constitutes a part of a cavity side inner surface defining a left side cavity of the left side mold and is capable of protruding and moving inward of the left side cavity. After the molding step, the right side mold and the left side mold are separated from each other to separate the right side cavity and the left side cavity from each other, and the left side auxiliary member is projected to the inside of the left side cavity while the right side auxiliary member is projected to the inside of the right side cavity to maintain the resin molded molding sandwiched between the right side auxiliary member and the left side auxiliary member.SELECTED DRAWING: Figure 14
