The invention relates to a pin with at least one sleeve-shaped component having a longitudinal axis and a base. According to the invention, the wall thickness of the base changes along a closed line which lies on the surface of the base facing the interior of the sleeve-shaped component and runs concentrically to the longitudinal axis.

The invention relates to a pen with a refill and a rotary mechanism for adjusting the refill in the longitudinal direction of the pen, wherein the rotary mechanism comprises a spindle and a threaded nut and the internal thread of the threaded nut is divided at least in sections into first thread segments which each extend over less than 360° in the circumferential direction. According to the invention, it is provided that the external thread of the spindle is divided at least in sections into second thread segments which extend over less than 360° in the circumferential direction, the distance in the circumferential direction between second thread segments that are adjacent in the circumferential direction is lesser than the extension in the circumferential direction of the first thread segments and the distance in the circumferential direction between first thread segments that are adjacent in the circumferential direction is lesser than the extension in the circumferential direction of the second thread segments.

The present invention relates to a marking device comprising an elongated body defining a holding axis and a first marking end at a distal end. A first marking means is arranged to extend from the bod

A pen with a lead (18) and a rotary mechanism for adjusting the lead in the longitudinal direction of the pen, wherein the rotary mechanism has a spindle (16) and a threaded nut (22) and the internal thread of the threaded nut is divided at least partially into first thread segments (24, 26, 28) which each extend over less than 360° in the circumferential direction, characterized in that the external thread of the spindle (16) is divided at least partially into second thread segments (30, 32) which extend over less than 360° in the circumferential direction, the distance (A) in the circumferential direction between circumferentially adjacent second thread segments is smaller than the extent (B) in the circumferential direction of the first thread segments (24, 26, 28) and the distance (C) in the circumferential direction between circumferentially adjacent first thread segments is smaller than the extent (D) in the circumferential direction of the second thread segments.

A double-color pen, comprising a pen body (1), a rolling body (2) rollably provided on the head of the pen body, at least a pair of ink feed assemblies provided in the pen body, and reset devices (5)

The utility model discloses a refill holder which comprises an annular body, a first clamping part and a second clamping part, the first clamping part and the second clamping part are oppositely arranged on the two sides of the body, and a clamping channel is formed by the first clamping part, the body and the second clamping part. The first clamping part is obliquely folded in the direction close to the center shaft of the body, and when the refill is inserted into the clamping channel, the first clamping part is expanded to drive the second clamping part to be folded in the direction close to the center shaft of the body and to be clamped on the outer wall of the refill; the utility model further discloses a writing pen. According to the writing pen, through the arrangement of the refill holder, after the first clamping part is opened by the refill, the second clamping part can be driven to be close to the refill, so that the refill is clamped by the second clamping part, the refill is prevented from shaking in the pen holder to influence the writing experience, and the use comfort of the writing pen is improved.
