摘要： An expandable writing instrument has a writing end body section and a rear body section mounted to the writing end body section for relative axial and non-rotational movement between an extended position with the rear body section spaced away from the writing end body section, and a retracted position with the rear body section closer to the writing end body section. A spring in the writing end body section biases the cartridge upwardly. A helix cylinder is mounted for rotation and axial movement in the rear body section with a peg of the rear body section sliding in a track of the helix cylinder. The track is a closed loop with left and right hand helixes so that axial movement of the rear body section causes rotation of the helix cylinder continuously in one rotational direction. A shuttle receives a cartridge body and is mounted for axial movement in the helix cylinder. A shuttle cam on the shuttle is mounted for axial non-rotational movement to the writing end body section. Shuttle cam surfaces slidably engage cam surfaces of the helix cylinder and the cam surfaces include a high point that engages a flat portion of another cam surface for moving the shuttle with rotation of the helix cylinder, to project a writing tip of a cartridge out of the bottom opening in the extended position.
摘要翻译：可扩展书写工具具有书写端主体部分和后体部分，安装到书写端主体部分，用于在与书写端主体部分间隔开的延伸位置与后主体部分之间进行相对的轴向和非旋转运动;以及缩回位置，后体部分靠近书写端本体部分。书写端主体部分中的弹簧将盒向上偏置。螺旋缸被安装成用于在后体部分中的旋转和轴向运动，后体部分的钉在螺旋缸的轨道中滑动。轨道是具有左右螺旋线的闭环，使得后体部分的轴向运动导致螺旋缸在一个旋转方向上连续旋转。梭子接收盒体并安装成在螺旋缸中轴向移动。梭子上的往复凸轮被安装用于轴向非旋转运动到书写端本体部分。梭形凸轮表面可滑动地接合螺旋圆柱体的凸轮表面，并且凸轮表面包括接合另一个凸轮表面的平坦部分的高点，用于通过螺旋圆柱体的旋转来移动梭子，以将墨盒的书写尖端突出到底部开口处于延伸位置。
