The utility model discloses a kind of pressing mechanism of automatic pressing pen, belong to automatic pressing pen field, including pen body and pressing rod;Driving ring, rotatably set in pen body;Elastic reset piece, set on driving ring;Buckle piece, set on elastic reset piece, plug-in part, set on pressing rod and can be slidably inserted into buckle piece and buckle piece and buckle in buckling;Buckle piece is used to limit plug-in part, to prevent pressing rod from appearing false touch, elastic reset piece is used to provide elastic tension for buckle piece, so that it maintains current state.The pressing mechanism of automatic pressing pen of the utility model, through the limiting design of buckle piece to plug-in part, effectively prevent pressing rod false touch, simultaneously using the cooperation of driving ring, elastic reset piece and other structures, release limiting when needed, ensure normal pressing function, compared with prior art, significantly improve the stability and reliability of pressing pen use.

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.

To provide a writing utensil which enables stable writing by preventing a refill from rotating around an axial center in a cylindrical case.SOLUTION: A writing instrument in which a refill is housed in a cylindrical case, wherein the refill does not rotate around an axial center.SELECTED DRAWING: Figure 1

The utility model discloses a pressing pen which comprises an outer shell, a refill structure, a reset piece and a rotating ring rotatably arranged on the outer shell in a sleeved mode, the outer shell is arranged at the lower end of the refill structure in a sleeved mode, an annular structure is arranged in the middle area of the refill structure, and the annular structure is arranged outside the rotating ring in a sleeved mode in a sliding mode. A pressing telescopic structure is arranged on the outer side of the rotating ring, and a pressing telescopic matching structure is arranged on the inner side of the annular structure. When the pressing pen is used, a user presses the refill structure and the shell, and pressing stretching and retracting of the refill structure are achieved through cooperation of the pressing stretching and retracting structure and the pressing stretching and retracting matching structure. Compared with a traditional pressing pen, the upper end of the refill structure of the pressing pen is not provided with a pressing telescopic structure and the like, and the pressing telescopic structure and the pressing telescopic matching structure are both located on the outer side of the refill structure, so that the length of the refill structure can be basically the same as that of the whole pen; therefore, the ink storage amount of the refill structure is improved.

According to the writing pen with the rotatable inner tube, the front end of an outer pen holder is detachably connected with a pen point cap, the inner tube is contained in an inner cavity of the outer pen holder, a pen core is contained in the inner tube, the pen point end of the pen core is close to the pen point cap, and the non-pen-point end of the pen core abuts against a rotating module so that the pen core can be pushed when the rotating module rotates, and the pen point can be exposed out of the pen point cap; the rotating module comprises a rotating pressing head, a first-stage rotating transmission structural member and a second-stage rotating transmission structural member, the rotating pressing head is exposed out of the pen cap so as to receive applied rotating operation, one end of the first-stage rotating transmission structural member is connected with the rotating pressing head, and the other end of the first-stage rotating transmission structural member is connected with one end of the second-stage rotating transmission structural member; when rotating operation is applied to the rotating pressing head, the rotating pressing head is driven to rotate and drives the second-stage rotating transmission structural part to rotate, one end of the second-stage rotating transmission structural part abuts against the inner tube, and therefore when the second-stage rotating transmission structural part rotates, the inner tube is pushed, and the pen point is driven to be exposed out of the pen point cap.

This utility model discloses a pen, including a shell, an unlocking component, a first resetting component, and a pen refill with a tip. The shell has a receiving cavity that matches the pen refill. The upper and lower ends of the shell each have a first opening and a second opening that matches the pen tip, respectively. The side wall of the shell has an installation port. The pen refill is inserted into the receiving cavity through the first opening. The first resetting component connects the shell and the pen refill, and the first resetting component causes the pen refill to tend to move away from the shell. The unlocking component is movably disposed at the installation port. The outer side wall of the pen refill has a locking part that matches the unlocking component. The unlocking component moves relative to the shell, thereby locking or unlocking the unlocking component and the locking part. When the pen refill is used up, simply moving the unlocking component relative to the shell unlocks the unlocking component and the locking part, allowing a new pen refill to be inserted into the receiving cavity through the first opening, locking the unlocking component and the locking part, thus completing the pen refill replacement.

The utility model discloses a kind of pens, including shell and refill with nib;Shell is equipped with the accommodating cavity matched with refill in, and the upper and lower ends of shell are equipped with first opening and second opening matched with nib respectively;Refill is loaded into accommodating cavity from first opening;The outer side wall of refill is equipped with locking portion, and the inner side wall of shell is equipped with locking portion matched with locking portion. This pen when using, when refill is used up, only needs to operate refill relative to shell movement, i. e. locking portion and locking portion cooperation portion can be unlocked, new refill is loaded into accommodating cavity from first opening again, and operate refill relative to shell movement again, i. e. locking portion and locking portion cooperation portion can be locked, shell and refill are locked together, the replacement of refill is completed, and it is more convenient to use.
