所述保持块13包括保持块连接部13-1和具有U形开口的保持块止挡部13-2，其中所述保持块连接部13-1通过所述紧固螺栓连接到所述支架支撑部 12-2，所述保持块止挡部13-2限制异物(例如乘客的手部)进入所述壳体4内部的程度。
所述保护块13处于所述转动支架12和所述毛刷基体7之间。
根据本公开内容的上述各个实施例，如图14所示，所述异物防夹装置的第二保护组件还包括制动开关14。
在所述转动支架12的下面设置有制动开关14。
当异物(也可以是乘客的手部)通过所述毛刷基体7与所述扶手带2之间的间隙进入所述壳体4内部并且按动所述保护块13时，所述转动支架12转动。
随着所述转动支架12的转动，当所述制动开关14被所述转动支架12(支架支撑部12-2)按动时，所述制动开关14发出制动信号，所述自动扶梯1停止运行。
根据本公开内容的上述各个实施例，如图1所示，在所述壳体前部面板4-2上安装有雷达15。
所述雷达15的安装位置靠近所述自动扶梯1的出入口的地板。
所述雷达15通过发射雷达波和接收反射的雷达波判断是否有乘客进入或离开所述自动扶梯1。
根据本公开内容的上述各个实施例，在所述壳体侧部面板4-3的至少一个上设置有至少一个紧急制动按钮16。在出现任何紧急状况时，通过按动紧急制动按钮16能够使自动扶梯1立即停止。
所述紧急制动按钮16的安装位置靠近所述自动扶梯1的出入口的地板。
通过将雷达15和紧急制动按钮16整合在清洁装置3中，避免了因为安装清洁装置在传统位置上无法安装雷达和紧急制动按钮的技术问题，并且根据本公开内容的这种整合设计在扩展了具有安全装置的清洁装置的功能的同时还实现了清洁装置在结构上的紧凑性。
根据本公开内容的另一个实施例，提出一种自动扶梯1(如图1所示)，所述自动扶梯1包括如上所述的安全装置3。
基于本公开内容的自动扶梯和清洁装置在一起工作，其中扶手带是移动部件，清洁装置固定的。异物易于进入扶手带和清洁装置之间的间隙而被夹住。基于本公开内容的异物防夹装置可以防止异物进入。另外，基于本公开内容的异物防夹装置也可以保护例如乘客的手部不会被卡住。
前述公开内容提供了说明和描述，但并不旨在穷举或将实施方式限制为所公开的精确形式。可以根据以上公开内容进行修改和变化，或者可以从实施方式的实践中获得修改和变化。
即使在权利要求中叙述和/或在说明书中公开了特征的特定组合，但这些组合并不旨在限制各种实施方式的公开。实际上，许多这些特征可以以权利要求中未具体叙述和/或说明书中未具体公开的方式组合。尽管下面列出的每个从属权利要求可能仅直接依赖于一个权利要求，但各种实施方式的公开包括与权利要求集中的每个其他权利要求相结合的每个从属权利要求。
除非明确说明，否则本文中使用的任何元件、动作或指令都不应解释为关键或必要的。另外，如本文所用，冠词“一”和“一个”旨在包括一个或多个项目，并且可以与“一个或多个”互换使用。此外，如本文所用，冠词“该”旨在包括结合冠词“该”引用的一个或多个项目，并且可以与“一个或多个”互换使用。此外，如本文所用，术语“集”旨在包括一个或多个项目(例如相关项目、不相关项目、相关和不相关项目的组合等)，并且可以与“一个或多个”互换使用。在仅意图一项的情况下，使用短语“仅一项”或类似语言。另外，如本文所用，术语“具有”及其变体等旨在是开放式术语。此外，短语“基于”旨在表示“至少部分地基于”，除非另有明确说明。另外，如在本文所用，术语“或”在被串联使用时意图是包括性的，并且可以与“和/或”互换使用，除非另有明确说明(例如，如果与“或者”或“仅其中之一”结合使用)。
