作为可选的实施方式，每个动滑轮组32包括两个滑轮，两个滑轮固定往同一方向运动，并分别绕有一条USB线；USB线的一端连接一块书写板2的控制模组，另一端连接智能终端。具体的，动滑轮组32配合定滑轮31与滚动轴承33的运动，能够在书写板2运动的同时，对USB线进行收纳。USB线分别与书写板2的控制模组和智能终端6连接，属于本地通信的一种连接方式，方便将书写板2上的书写笔迹转换的电信号传输智能终端6。
作为可选的实施方式，如图4所示，滚动轴承33为外径小于或等于16毫米的微型轴承，滚动轴承33的轴心分布在两个平行平面，两个平行平面之间的距离为0.1~0.5毫米。具体的，书写框12与书写板2配套连接，起固定和保护作用。书写板2通过滚动轴承33能够在推拉时滑动，从而实现该书写板2无可书写面时换至另一书写板2书写。固定式外框11的每侧都布置有滚动轴承33，其中三个为一组。三个滚动轴承33的轴心分布在两个平行平面，其中一个在固定式外框11的内侧转角处做固定杠杆使用，另外两个滚动轴承33在实际运用时，作用于书写板2。在推拉书写板2时，这两个滚动轴承33做水平或垂直运动。平行平面的距离为本实施例的优选方案。
作为可选的实施方式，书写板2还能够将书写笔迹的坐标信息发送给智能终端6。具体的，书写板2上的书写笔迹，能够被书写板2上的电容感应膜及电容感应控制模组识别，转换为能够被智能终端6所识别的坐标信息，经由智能终端6的处理，在智能终端6上显示。
作为可选的实施方式，推拉式电容白板书写系统还包括电容感应书写笔4和电容感应板擦5；电容感应书写笔4上的笔壳为导电材料，墨水含导电溶剂，笔芯直径大于2毫米，能够在书写板2上书写出各种颜色的墨迹，并能被感应到墨迹的坐标位置；电容感应板擦5的板擦面为导电材料，在擦除电容感应书写笔4的书写墨迹的同时，擦除书写墨迹的坐标位置的数字笔迹。具体的，电容感应书写笔4的笔壳、墨水、丝印和标签都设置有导电材料，是为了加强电容感应书写笔4的导电能力。电容感应书写笔4的导电能力关系着电容感应膜感应到的墨迹坐标的准确性，使书写墨迹在电容感应膜上显示的更完整、更准确。笔芯的直径大于2毫米为本实施例的优选方案。电容感应书写笔4可内置不同颜色的导电墨水，能够在书写膜上写出各种颜色的笔迹。电容感应板擦5包括板擦壳和板擦面，板擦面与板擦壳紧密连接。板擦壳由用户手持使用，板擦面与书写板2直接接触。其中，板擦面为导电体，在实际应用时与书写板2下的电容感应膜反应，擦除电容感应书写笔4在电容感应膜下感应到的墨迹的坐标位置，方便电容感应膜在书写板上定位重新书写的墨迹坐标位置。同时，将墨迹坐标显示的数字笔迹也进行擦除。板擦面为耐磨导电海绵、耐磨导电布或耐磨导电棉，能够延长电容感应板擦5的使用寿命。
作为可选的实施方式，如图5所示，书写板2包括基板、书写膜、电容感应膜及电容感应控制模组；基板的厚度小于10毫米；书写膜覆盖在基板的上表面；电容感应膜设置在基板的下表面；书写板通过电容感应控制模组与智能终端进行通信。具体的，书写板2由多结构组成，最外层是书写膜，中间是基板，基板下覆盖着电容感应膜。基板的厚度限制是为了使书写板2更轻便。用户在书写膜上书写，基板覆盖住电容感应膜，能够保护电容感应膜使用时不受破坏。电容感应控制模组通过电容感应膜感应，将电容感应书写笔4书写的坐标位置转换成电信号，并实时发送给智能终端6。智能终端6在显示的时候，同时保存显示信息在智能终端6的储存单元中，方便后续信息的调取。
