A mechanism of a daily commodity ejecting and retracting device includes an operating portion provided to rotate around a center line vertical to an axis line of a shaft tube in relation to the shaft tube between a first rotation position and a second rotation position. A rod portion is coupled within the shaft tube to rotate around a first axis line and is coupled to the daily commodity to rotate around a second axis line which is parallel to the first axis line. An eccentric position of the first axis line is set so that the daily commodity is immersed into the shaft tube via the rod portion when the operating portion is rotated to the first rotation position, and the daily commodity protrudes out of a leading end port of the shaft tube via the rod portion when the operating portion is rotated to the second rotation position.

A marking instrument having a plurality of removable writing nibs serially aligned so that an operator can remove a spent or fluid-affected writing nib and, thereby, access a fresh writing tip.

A writing instrument comprising a body extending along an axial direction and an erasing device comprising an eraser, the erasing device being disposed at an axial end of the body of the writing instrument, the eraser being able to assume a use position and a protection position, the eraser being configured to switch from the use position to the protection position by a displacement of the eraser by means of an actuation device of the erasing device, the actuation device being configured to be actuated along a axis perpendicular to the axial direction.

A pen structure with a glass smasher has the glass smasher mounted at the front end of a pen. When a user holds the pen and presses the front end (i.e., the smashing cone) of the smashing rod of the glass smasher forcibly against a glass obstacle, an impact block will strike the rear section of the smashing rod vigorously such that the smashing cone is instantly driven to smash the glass obstacle. A ballpoint/rollerball refill is detachably provided in the pen and is at least 6 cm long in order to contain enough ink. The overall length of the pen is at least 10 cm so that the pen can be easily held while the user writes or draws with the ballpoint/rollerball tip and while the user applies a force to a glass obstacle through the front end of the smashing rod to smash the glass obstacle.

A writing implement includes a housing for receiving a refill, an operating side and a writing side. An adjustment mechanism in the housing has a guide bushing and a cam pin concentrically arranged therein and spring-loaded along the longitudinal axis on the refill, which cam pin engages an end of the refill. The cam pin has at least two locking positions, which are offset along the longitudinal axis. The writing implement includes a control arrangement having a resetting device, a freewheel couplable with an operating unit arranged at the operating side and a cam bushing couplable with the freewheel. The resetting device exerts a resetting force onto the operating unit. The freewheel is a rotatably supported body having a circumferential recess and forms an operative connection in a region with a second body that is rotatably supported and concentrically thereto. One of the first and second rotatably supported bodies is freely rotatable around its longitudinal axis in an angle range and transfers a rotation from the operating unit to the cam bushing outside of this range.
