A writing instrument includes a body, a nosecone, and an adaptor each being of generally hollow tubular shape. Each the body, the nosecone, and the adaptor each have a first end and a second end. The first end of the adaptor is configured to slidably couple to the nosecone second end. The second end of the adaptor is coupled to the first end of the body. The writing instrument includes a writing element with a mounting end and a writing end where the mounting end is removably coupled to the second end of the body. The writing instrument includes a locking mechanism configured to selectively lock the nosecone in a storage position or a writing position. In the storage position, the nosecone extends and covers the writing end. In the writing position, the nosecone retracts and the writing end of the writing element extends beyond the nosecone.

A push button consists of component parts including a plunger, a retainer, a spring and an end cap. The plunger reciprocates within the retainer which has three main portions: an upper portion closely holds the button on the top of the plunger and includes a rectilinear recess that can receive a square midsection of the plunger. A middle portion of the retainer comprises an enlarged cavity that provides the side clearance for the plunger pin's enlarged square midsection to rotate. The cavity is bounded above and below by opposing roof and floor camming structures which engage the corners of the plunger midsection that causes it to rotate. A spring within the retainer biases the plunger upward. An end cap affixed to the bottom of the retainer captivates the plunger and spring assembly and provides attachment means to affix the push button assembly to a supporting structure.

An adjustment pen, including a pen body, the pen body including a pen tip, wherein the adjustment pen further includes a light emitting unit, a control switch and a power supply module which are carried by the pen body, the light emitting unit is connected with the control switch and the power supply module to form an illumination circuit, the control switch is configured to control ON and OFF of the illumination circuit, and the light emitting unit is configured to emit a light beam toward the pen tip.

An input touch pen includes a digitizer refill contained inside a shaft tube and including a contact tip and a stepped tip portion rearward thereof, and a knock member protruding from an opening at a rear end of the shaft tube. The contact tip can protrude and retract through an opening at a tip end of the shaft tube. The stepped tip portion has a larger diameter than the opening at the tip end. A relationship A>X>Y is satisfied, wherein X represents a knock stroke of the digitizer refill, A a distance from the stepped tip portion to an inner surface at the tip end side when the contact tip is sunken inside the opening, and Y a distance that the contact tip is moved by operation of the knock member from a state of protruding from the opening to a state of being sunken inside the opening.

A thermochromic writing instrument capable of causing curiosity and interest of a user by configuring an eraser to be easily separated from the main body of the thermochromic writing instrument and to be shaped into various character dolls. A rotation member is inserted into a pen body and a hollow upper cover is detachably coupled to an outside of the upper portion of the pen body, a first eraser is connected to the rotation member by a connection member, a connection portion of an operation member is disposed in a groove formed at one side of the side wall of the pen body, the first body portion of the operation member is inserted into the pen body and a clip portion of the operation member is exposed to the outside of the pen body.
