图 1为现有技术一个实施例的结构示意图。 图中显示，现有技术中，伸缩式电动推杆主要由杆体 1.1、 电源 2、 手控器等构件组成， 杆体 1上设置有电机 1.1、 伸缩杆 1.2， 杆体内部设置有传动组件、 螺杆、 行 程控制开关， 伸缩杆 1.2上设置有安装孔 1.21 (负载通过安装孔与伸缩杆连接固定）， 还设置有安装座 4， 杆体 1通过安装座 4安装固定， 电机 1.1通过传动组件驱动螺杆转动并驱动伸缩杆 1.2伸缩。 图中显示， 现今的伸缩式电动推杆没有设置力检测元件， 因而不能对作用在负载上的推拉力进行实时检测， 因而难以 满足更高的要求。
由于属于现有技术， 本文中， 设置在杆体内部的传动组件、 行程控制开关没有在图上显示出来。 图 2、 图 3为本发明第一个实施例的结构示意图， 其中图 3为局部结构放大示意图。 图中显示， 本例 提出的伸缩式电动推杆， 主要由杆体 1.1、 电源 2、 手控器等构件组成， 杆体 1上设置有电机 1.1、 伸缩杆 1.2， 杆体内部设置有传动组件、 螺杆、 行程控制开关， 还设置有安装座 4， 杆体 1 通过安装座 4安装固 定， 电机 1.1通过传动组件驱动螺杆转动并驱动伸缩杆 1.2伸缩。 与现有技术不同的是， 在所述伸缩杆 1.2 的端头上还设置有力传感器 3， 所述力传感器 3—端与伸缩杆连接而另一端与负载连接， 伸缩杆 1.2通过 力传感器 3将力传递至负载。
图 3为传感器的结构放大示意图， 图 3显示， 力传感器 3的一端设置有伸缩杆连接端 3A、 力传感器 3 的另一端设置有负载连接端 3B， 在伸缩杆连接端 3A上设置有杆端安装孔 3. 1， 在负载连接端 3B上设置有 负载端安装孔 3. 2， 在力传感器 3上设置有检测元件 3. 3。 图 2显示， 力传感器 3的伸缩杆连接端 3A插接 在伸缩杆 1. 2的端头上并通过固定螺栓 5安装固定。
图 2显示， 本例中， 在伸缩杆 1. 2端头上设置力传感器 3， 使其作为伸缩杆 1. 2与负载之间的力传递 件和检测件， 通过力传感器 3可以对负载的受力情况进行实时检测， 以便满足更高的使用要求。 比如， 除 了可以实时检测力的大小之外， 还可以将与其它配套仪器配合， 比如利用力传感器的峰值测试仪， 通过设 置峰值来限定电动推杆的最大工作推拉力， 达到保护负载和实现更高控制的目的。
