The outer shell comprises a lower shell and an upper shell, and the upper shell is rotatably arranged on the lower shell; the inner shell is sleeved with the outer shell in a sliding mode, and a clamping jaw is arranged at the upper end of the inner shell; the clamping driving piece is arranged between the clamping jaw and the shell; the first reset piece is arranged between the clamping jaw and the shell and connected with the clamping driving piece and the upper shell; the refill is sleeved with the inner shell in a sliding mode, and a pen point is arranged at the lower end of the refill; the upper shell and the inner shell are respectively provided with a driving part and a driving matching part which are matched with each other, and the upper shell rotates relative to the lower shell so as to drive the inner shell to move up and down relative to the outer shell. When the rotary telescopic pen is used, the upper shell and the inner shell are provided with the driving part and the driving matching part which are matched with each other respectively, so that the inner shell moves up and down relative to the outer shell, and the pen point is exposed or retracted.

The utility model discloses a length-adjustable pen, and aims to provide a length-adjustable pen which is adjustable in length and good in adjustment effect. Comprising a lower pen holder, a pen core is installed in the lower pen holder, and a sliding block is arranged at the upper end of the outer side wall of the lower pen holder; the upper penholder is connected with the lower penholder in a sleeved mode, a plurality of sliding grooves are formed in the upper penholder, guide grooves are formed among the sliding grooves and communicated with the sliding grooves, and the sliding blocks are arranged in the sliding grooves and can slide along the guide grooves. The multifunctional pen has the advantages that the sliding blocks of the lower pen holder are installed in the different sliding grooves of the upper pen holder, the length of the pen can be adjusted, and therefore it can be guaranteed that the adjusting effect is good.

This application discloses a multi-segment pen, belonging to the field of pens. A multi-segment pen includes: a pen body, which comprises: a pen tip; a pen nib threaded to one end of the pen body; a pen cap disposed at the other end of the pen body; a pen refill movably disposed on the pen body; a pen sleeve, configured as multiple segments, sequentially fitted onto the pen body; an anti-slip strip disposed on the pen sleeve; and a guide groove formed on the pen body, the guide groove corresponding to the guide strip. Multiple pen sleeves are disposed on the outside of the pen body. During installation, the pen tip can be rotated, and then the pen sleeve is fitted onto the pen body. The pen sleeve is fixed in place by the pen cap and pen tip. In practice, the pen sleeves can be made in various colors, allowing users to freely assemble them according to different color schemes, achieving personalized DIY and enhancing the fun. Meanwhile, the anti-slip strip is serrated, which on the one hand makes the grip more stable and provides a better feel, relieving hand fatigue; on the other hand, it provides better anti-slip for people with sweaty hands.

The rotary pen is characterized in that the rotary pen comprises a pen tube, a refill and a pen cap module, the refill is provided with a pen point, one end of the pen tube is conical so that the refill can be embedded in the pen tube, and the pen point can penetrate through the conical end and is exposed out of the pen tube; the pen cap module is of an inner and outer ring structure, the inner and outer ring structure comprises an inner ring layer and an outer ring layer, the inner ring layer can be arranged at the conical end in a sleeving mode so that the inner ring layer and the pen tube can form packaging of the refill, and the outer ring layer can be arranged on the inner ring layer in a sleeving mode in the mode that the outer ring layer can rotate in the axial direction of the inner ring layer.

The utility model relates to a telescopic marking pen which comprises a pen shell, a rotating plug and a pen inner container, a spiral groove is formed in the side wall of a containing cavity of the pen shell, the rotating plug is arranged on the pen shell in a rotating mode, a guide rail sleeve is arranged on the rotating plug, the pen inner container is arranged in the containing cavity, and a second end matched with the pen inner container is movably arranged in a telescopic cavity of the guide rail sleeve. When the rotating plug is rotated, the guide rail sleeve and the pen inner container in the guide rail sleeve can be driven to rotate, the guide column on the pen inner container moves in the spiral groove and the telescopic groove in the guide rail sleeve at the same time, the position of the pen inner container in the guide rail sleeve can be changed, and the pen inner container can be driven to rotate. Therefore, the first end of the pen inner container movably protrudes out of the second end of the pen shell, the length of the pen point of the telescopic marking pen is adjusted, and meanwhile under the guiding effect of the guide rail sleeve, the first end of the pen inner container can stably and movably protrude out of the second end of the pen shell.

A writing instrument (1) comprising at least two writing cores (4) received in a body (2), each writing core (4) having a support and a rotating element (5) mounted at a rear end of the body (2), the rotating element (5) and the writing cores (4) comprising complementary guide elements configured so that the rotation of the rotating element (5) advances each of the writing cores (4) in the body (2) in turn into a writing position, characterized in that the mechanical holders of the supports have at least one respective spacer projecting laterally from the front end of the mechanical holder so as to maintain a gap between the tip (7) of the writing core (4) and the body (2) in a retracted position of the writing core (4) and during the transition from the retracted position to the writing position. Figure 2

The utility model relates to a writing instrument (1), it includes being contained in main part (2) at least two writing core (4) and installing on the rear end part of main part (2) rotating element (5), each writing core (4) all have support, rotating element (5) and writing core (4) include complementary guide element, the complementary guide element is configured to make rotating element (5) the rotation can push each writing core (4) in turn to writing position, its characterized in that, the movable core frame of support has at least one corresponding strut, and the strut protrudes transversely at the front end part of movable core frame, thereby keeping the interval between the tip (7) of writing core (4) and main part (2) when writing core (4) is in retracted position and during the transformation from retracted position to writing position.

The present application discloses the double-head marker pen, and relates to the field of marker pen production technology, including a first penholder, a second penholder and a connecting tube ; one end of the first penholder is formed with a first pen head, and one end of the second penholder is formed with a second pen head; and an end of the first penholder away from the first pen head is detachably connected with an end of the second penholder away from the second pen head by the connecting tube.

To provide a writing implement capable of drawing a line by using capillary force, capable of freely adjusting the width of the line while drawing the line, and capable of drawing a line of almost the same width at the beginning and end of use of the writing implement. [Solution] The felt-tip pen 1 comprises an ink storage section 11, a collector 17, and a core 29 that uses capillary force to suck up the ink delivered by the collector 17, delivers the sucked ink from the tip, and deposits it on the paper surface; even with repeated writing, the rate of change in the width of the line drawn at the end of use compared to the width of the line drawn at the beginning of use is 10% or less.
