Connection structure and pen implement

ActiveCN224335364UPropelling pencilsBall-point pensStructural engineeringLarge deformation
The application provides a connecting structure and a pen, and relates to the technical field of pens. The connecting structure comprises a first connecting part and a second connecting part connected with each other. The second connecting part comprises a receiving groove, and the first connecting part is arranged in the receiving groove. The first connecting part comprises a plurality of first connecting arms capable of elastically deforming. The plurality of first connecting arms are arranged to form a slot. The first connecting part is connected with a first structural member outside the connecting structure through the slot, and each first connecting arm is clamped to the first structural member. The outer periphery of the second connecting part is connected with a second structural member outside the connecting structure. In the connecting structure provided by the application, the second connecting part is connected with the second structural member alone, and each first connecting arm does not need to be connected with the second structural member. The first connecting arms can avoid being limited by the second structural member, have a larger deformation space, can better wrap the first structural member, i.e. a pen core, and can reduce the size precision requirements of the connecting structure and the pen core, and are more beneficial to production.

A portable pencil

ActiveCN224375195UPropelling pencils
This utility model belongs to the field of stationery technology, specifically relating to a portable pencil, including a pencil barrel with a rotating handle rotatably mounted on it, and a pencil tip threadedly connected to the rotating handle; it also includes: a lifting cylinder slidably disposed within the pencil barrel, the lifting cylinder being threadedly connected to the rotating handle, and a pencil tip disposed at the lower end of the lifting cylinder; a lead feeding mechanism disposed within the lifting cylinder; and a pressing handle slidably disposed on the lead feeding mechanism. This portable pencil, through the threaded connection between the rotating handle and the threaded portion of the lifting cylinder, combined with a sliding limit design of a sliding strip on the lifting cylinder within the pencil barrel, allows for easy and flexible adjustment of the pencil tip extension or retraction by simply rotating the rotating handle during use. When the pencil is not in use, the pencil tip can be retracted, effectively preventing damage from impacts; during writing, the pencil tip can be adjusted to a suitable length according to personal usage habits.

Mounting structure and writing instrument having this mounting structure

ActiveJP7863459B2Propelling pencilsStructural engineeringMechanical engineering
To suppress damage to a magnet in a mounting structure using the magnet.SOLUTION: A mounting structure 20 includes a main body 30 and a handwriting changing tool 80 that changes handwriting. One of the main body 30 and the handwriting changing tool 80 has a magnetic member 87. The other of the main body 30 and the handwriting changing tool 80 has a magnet 50 facing the magnetic member 87 in an axial direction da, and a protective member 60 that prevents the magnet 50 and the magnetic member 87 from coming into direct contact. The handwriting changing tool 80 is detachably attached to the main body 30 by the magnetic force of the magnet 50.SELECTED DRAWING: Figure 2

Mechanical pencil

ActiveJP7882749B2Propelling pencils
To provide a mechanical pencil provided with a rotational drive mechanism for rotating a writing lead, in which a retreating amount of the writing lead is further reduced.SOLUTION: A mechanical pencil 1 includes: a barrel 5; a chuck unit 10 that allows a writing lead to advance and prevents it from retreating; and a rotational drive mechanism 30 that has a rotor 40, and rotates and drives the rotor 40 in one direction by receiving a retreat operation in an axial direction by writing pressure received by the writing lead held by the chuck unit 10 and an advance operation in the axial direction by release of the writing pressure. A retreating amount m due to the retreating operation is within a range of 0.05 to 0.3 mm.SELECTED DRAWING: Figure 7
