在一种实施方案中，驱动机构m还包括变速箱m4，变速箱m4安装在驱动安装区1.10，丝杆上端、减速齿轮m2以及传动齿构件安装在变速箱m4内，电机m1与变速箱m4固定连接。采用上述结构，驱动机构m整体的体积更小。传动齿构件为蜗杆，减速齿轮m2为蜗轮，这样可以进一步减少驱动机构m的厚度，从而进一步减少上支座1.1的厚度。
参见图1、7和图8，在一种实施方案中，电机m1水平布置。通过这样的设置，可以合理利用上支座1.1水平方向的空间，使上支座1.1的高度更小。
参见图7和图8，在一种实施方案中，变速箱m4包括上下布置的第一箱件m41和第二箱件m42，第一箱件m41内壁设置有第一轴承安装部m411，第二箱件m42内壁对应设置有第二轴承安装部m421以及贯穿第二轴承安装部m421中部的丝杆装配孔m422，丝杆R1上端穿出减速齿轮m2上侧，并且丝杆R1上端位于减速齿轮m2的上侧和下侧分别连接有第一平面轴承m51和第二平面轴承m52，第一平面轴承m51装配在第一轴承安装部m411，第二平面轴承m52装配在第二轴承安装部m421。丝杆R1上端采用第一平面轴承m51和第二平面轴承m52与第一箱件m41和第二箱件m42装配，利用第一平面轴承m51和第二平面轴承m52的轴向承托特性与第一轴承安装部m411和第二轴承安装部m421装配，实现对丝杆R1的轴向定位，这样可以采用通用的丝杆R1而无需在丝杆R1上加工轴向定位结构，经济性更好。
为了保持丝杆R1的同心度，在丝杆装配孔m422下部还装配有径向轴承m53，丝杆R1安装在径向轴承m53，径向轴承m53是指可以实现同轴度保持的轴承，如滚子轴承。为了方便安装径向轴承m53，在丝杆装配孔m422下部设置有下侧开口的第三轴承安装部m423，径向轴承m53安装在第三轴承安装部m423内并且通过螺钉固定下侧。
在一种实施方案中，减速齿轮m2由塑料制成，通过注塑固定在丝杆R1上，丝杆R1连接减速齿轮m29的部位设置有销孔R10，销孔R10内安装有销（未示出），采用这种结构可以使减速齿轮m29和丝杆R1注塑连接更稳固。
在一种实施方案中，热压板组件H包括连接盘H1、电热板组件H2和若干弹性缓冲件H3，连接盘H1中部与螺母R2固定连接，连接盘H1和电热板组件H2通过若干弹性缓冲件H3连接；电热板组件H2上侧设有围绕连接盘H1外侧的下围壁H211，上支座1.1下侧设有与下围壁H221活动嵌合的上围壁1.11。通过配置活动嵌合的下围壁H221和上围壁1.11，隐藏热压板组件H与丝杆螺母副R，使产品外观整体性更好，更美观。
上围壁1.11顶部设置有连接孔，上围壁1.11的连接孔通过螺钉与上支座1.1连接。
连接盘H1设置两个以上的导向座H4，上支座1.1对应设置有与导向座H4配合的导向杆H5，导向杆H5和导向座H4除了起到导向作用之外，还可以对连接盘H1起到角向定位作用。
在一种实施方案中，电热板组件H2包括发热基体H21以及上盖H22，下围壁H221与上盖H22分体设置，上盖H22设置有围壁连接凹槽H220，下围壁H221下端适配地连接在围壁连接凹槽H220内。由于使用者观察角度在上支座1.1上方，采用这种结构在使用过程中下围壁H221和上围壁上围壁1.11接合端不容易看到，使产品的美观性更好，而且下围壁和上围壁之间不容易进异物。
在一种实施方案中，下围壁H221与围壁连接凹槽H220之间通过扣结构k1和扣位k2可拆卸连接。采用这种结构，方便装配和拆卸。
弹性缓冲件弹性缓冲件H3包括连接件H31和弹性件H32，连接件H31下端与发热基体H21固定连接，连接件H31上端与连接盘H1具有竖向活动空间地连接，弹性件H32套设在连接件H31外并弹性作用在连接盘H1和电热板组件H2之间，优选下端作用在发热基体H21上。本实施例中，连接件H31为螺柱，连接盘H1上设置有连接孔，螺柱可活动穿过连接孔与热基体H21螺接，弹性件H32为弹簧。
实施例1和实施例2的一些技术特征和技术效果可以相应的组合和体现，在此不作重复描述。
根据上述说明书的揭示和教导，本实用新型所属领域的技术人员还可以对上述实施方式进行变更和修改，本实用新型并不局限于上面揭示和描述的具体实施方式，对本实用新型的一些修改和变更也应当落入本实用新型的权利要求的保护范围内。
