图 2是本发明实施例第一辅助手柄与固定座分离后示意图。
图 3是本发明实施例第一辅助手柄示意图。
图 4是本发明实施例第二辅助手柄示意图。
图 5是本发明实施例电动工具的电路示意图。
具体实施方式
下面结合附图对本发明做进一步说明。
如图 1所示是本发明实施例电动工具示意图， 其是一种打草机， 其包括机体 和手柄组件， 所述手柄组件包括第一辅助手柄 5， 所述机体包括连接管 4， 连接 管 4一端设有机头 1， 机头 1内设有电机， 所述机头 1下方设有工作头 2， 电机 带动工作头 2进行作业。工作头 2后部设有护罩 3， 防止工作时从地面飞起的碎 石伤及后方的用户。 所述连接管 4另一端设有动力源 6， 给机头提供工作动力， 本实施例的动力源 6为电池。所述动力源 6前方设有握持部 7， 用户可利用握持 部 7操作打草机， 握持部 7上设有操作按钮 71。 所述动力源 6与机头 1内电机 和操作按钮 71等部件之间的电路连接线都设置在电动工具机体内部， 即电路连 接线都布置在连接管 4内部， 无电线外露， 使得机器更加美观。
如图 2和 3所示， 所述第一辅助手柄 5与机体上的固定座 9可分离或配接， 所述连接管 4上设有电连接座 8， 其设置在固定座 9中， 固定座 9固定在连接管 4上。所述电连接座 8上设有多个插孔， 本实施例中优选三个插孔， 分别为第一 插孔 81、 第二插孔 82和第三插孔 83， 所述三个插孔排列成三角插孔。 所述第 一辅助手柄 5包括 U形管 52， U形管 52上设有第一配接座 90， 第一配接座 90 固定在第一辅助手柄 5上， 所述第一配接座 90上设有第一电连接头 50。所述连 接管 4上设有通孔 54， 用于将第一辅助手柄 5固定在机体上。所述 U形管 52两 端设有操作部 51， 所述操作部 51上设有控制按钮 53， 用户可握住操作部 51操 作打草机。 所述控制按钮 53与电连接头 50之间的电路连接线设置在 U形管 52 内， 因此第一辅助手柄 5没有外露的连接线。 所述第一电连接头 50包括两个插 头， 分别为第一插头 501和第二插头 502， 所述插头能够和电连接座 8上的插孔 配接， 从而使控制按钮 53接入机体主回路中， 以控制电动工具运转。 所述手柄 组件还包括固定装置， 使得当固定座与第一配接座配接时不会脱离， 所述固定 装置可以设置在固定座和第一配接座， 例如常见的卡扣结构， 固定装置也可以 是其他形式， 只要能够实现将固定座和第一配接座固定在一起。 的本实施例中， 通过螺钉固定， 所述固定座 9和第一配接座 90上设有螺钉孔， 第一辅助手柄 5 上设有通孔 54， 螺钉 91依次穿过固定座螺钉孔、通孔 54然后打入配接座 90上 螺钉孔， 以此将固定座与配接座固定在一起， 同时使第一辅助手柄 5 固定在固 定座与配接座之间， 所述螺钉为自攻螺钉。 当需要使用第一辅助手柄 5 时， 将 所述固定座 9和第一配接座 90配接， 此时所述电连接座 8和第一电连接头 50 也配接在一起， 使得第一辅助手柄 5与电连接座 8同步实现机械连接和电性连 接。
如图 4所示是本发明实施例另一种辅助手柄， 为了满足不同用户的需求， 本 发明的手柄组件还可以配置第二辅助手柄， 所述第二辅助手柄 10为 J形手柄， 与上述 U形手柄的区别在于 J形手柄造型不同， 同时 J形手柄上可不设置控制 电动工具工作的控制按钮， 因此当电动工具使用此种手柄时， 需要使用电动工 具机体上的控制按钮， 即上述操作按钮 71来控制电动工具运作。 J形手柄上设 有第二配接座 60， 所述第二配接座 60上设有第二电连接头 103， 第二电连接头 103包括第一插头 101和第二插头 102， 第二电连接头 103可以与上述电连接座 8相配接。 由上述描述可知， 手柄组件配置的辅助手柄可以是各种形状结构， 只 要具有电连接头与电动工具机体上的电连接座配接， 即能够实现电连接和机械 连接， 当第一电连接头 50或第二电连接头 103与电连接座 8配接后， 所述固定 座 9和第一配接座 90或第二配接座 60也配接在一起， 可通过螺钉或其他方式 固定在一起。
下面结合图 5对本发明的设计做进一步说明， 所述电动工具包括手柄组件， 所述手柄组件包括第一辅助手柄 5和 /或辅助手柄 10， 所述辅助手柄 5、 10上分 别设有电连接头 50、 103， 需要使用第一辅助手柄 5时， 将所述固定座 9和第一 配接座 90配接， 此时所述电连接座 8和第一电连接头 50配接， 此时第一插头 501和第二插头 502分别插入第一插孔 81和第二插孔 82， 因此图 5电路图中的 第一节点 61和第二节点 62之间导通， 此时开关 S1可控制机器电路通断， 所述 开关 S1即为第一辅助手柄 5上的控制按钮 53。当需要使用不带控制按钮的 J形 手柄时， 将所述固定座 9和第一配接座 90分离， 此时所述电连接座 8和第一电 连接头 50也分离， 电路第一节点 61和第二节点 62之间断开， 将第二辅助手柄 10上的第二配接座 60与固定座 9配接， 第二电连接头 103与电连接座 8配接， 此时第一插头 101和第二插头 102分别插入第三插孔 83和第二插孔 82，因此图 5中第二节点 62和第三节点 63之间导通， 此时开关 S2可控制机器电路通断， 所述开关 S2即为上述操作按钮 71。 因此辅助手柄 5、 10与固定座 9配接时能够 接入不同的电路。 因此本发明不仅可以实现辅助手柄与固定座在机械结构上可 分离或连接， 同时能够实现电性连接或断开。 而且， 通过使用不同的电连接头 可实现工作电路切换， 以此来切换机器的控制方式， 而且可根据客户不同的操 作要求来配置不同的辅助手柄， 避免对各种操作方式的机器辅助手柄进行二次 开发。
需要指出的是， 上述较佳实施例仅为说明本发明的技术构思及特点， 其目的 在于让熟悉此项技术的人士能够了解本发明的内容并据以实施， 并不能以此限 制本发明的保护范围。 凡根据本发明精神实质所作的等效变化或修饰， 都应涵 盖在本发明的保护范围之内。
