(EN) The invention discloses a pen change device used for slab stone engraving. The pen change device comprises a front plate, a rear plate, a rotary disc, a connecting bracket, a pen sleeve, a marking penand an actuator, wherein the front plate, the rotary disc and the rear plate are sequentially arranged in parallel; the front plate is fixed to the rear plate by the connecting bracket; the surface of the front plate is provided with a circular ring shaped bulge; an opening is formed in the circular ring shaped bulge; a first inclined surface for guiding the pen sleeve to rotate is arranged on the side wall of the opening; a plurality of mounting parts are arranged in the peripheral direction of the rotary disc, and the pen sleeve is rotatably arranged on the mounting parts; the radial bulgedposition of the rear plate is provided with a limiting block to limit rotation at the opening of the position of the pen sleeve; the actuator is arranged on the front plate or the rear plate, and isconnected to the rotary disc; the actuator is utilized to drive the rotary disc to rotate; and the marking pen is detachably arranged in the pen sleeve. The pen change device utilizes a rail formed between the front plate and the rear plate, and utilizes the rotary disc, so that the marking pen moves along the rail, and therefore, the pen change function is realized, work efficiency is improved, and pen change time is shortened.
(ZH) 本发明公开了一种用于石板雕刻的换笔装置，包括前板、后板、转盘、连接支架、笔套、划线笔和致动器，前板、转盘和后板依次平行设置，利用连接支架将前板和后板固定，前板表面设置圆环形凸起，在圆环形凸起上设置开口，并开口侧壁上设置引导笔套转动的第一斜面；转盘周向设置若干个安装部，笔套转动设置在安装部上，后板径向突出设置限位块，以限制笔套位置开口处时转动，致动器设置在前板或者后板上，并且与转盘连接，利用致动器驱动转盘转动，划线笔可拆卸的设置在笔套内。换笔装置利用前板和后板之间形成的轨道，利用转盘的转盘，使得划线笔沿轨道移动，实现换笔功能，提高了工作效率，减少了换笔时间。
