下面结合附图对本发明做进一步说明。 应该清楚， 附图 中所描述的本发明的具体实施方式仅为说明本发明用， 并不 构成对本发明的限制。 本发明的保护范围由所附的权利要求 书进行限定。
图 1为本发明中一种可替换工具头的多用途组合工具的 装配分解示意图。 如图 1所示， 本发明中的多用途组合工具 100包括工具柄 10和工具头 20。 所述的工具柄 10的一端带 有装配插槽 101， 所述的工具头 20带有包塑装配端 201， 包 塑装配端 201的形状和尺寸和装配插槽 101的形状和尺寸相 适应； 在所述的装配插槽 101的壁及包塑装配端 201上分别 带有至少两个装配孔 30， 在包塑装配端 201和装配插槽 101 配合到位时所述的装配孔对准并采用螺钉 50拧紧固定。
所述的装配插槽 101 内设置多个定位销 102， 而在包塑 装配端 201上设置相应的多个定位槽 202，所述的定位销 102 和定位槽 202在工具头 20插入工具柄 10时相互吻合， 从而 起到限位作用。
所述的工具柄 10与带有装配插槽 101 —端相对的另一 端优选带有 TDT型手把 103。TTD型手把 103设计中溶入了 两个 T型手把和 D型手把的优点， 在铲物体时， 操作者可以 用手握住手把中间的 D型圈， 操作方便， 得心应手。 而在挖 土作业时， 又可用双手左右分别握住两个 T手把的两侧， 向 后用力， 使挖土变得轻松省力。
图 2为图 1中可替换工具头的多用途组合工具装配插槽 从一角度观察得到的立体示意图。 从图 2中可以看出， 在所 述的装配插槽 101 的一个壁上带有 4个定位销 102， 所述的 定位块和所述的包塑装配端 201上相应的四个定位槽在安装 到位时相互吻合。 当然， 所述定位块和定位槽的数量可以改 变， 但至少为一个。
图 3为图 1中已装配好的可替换工具头的多用途组合工 具。 将包塑装配端 201插入装配插槽 101并配合到位， 然后 采用螺钉 50插入装配孔 30拧紧固定就得到本发明中的一种 组合工具， 如图 2中所示的组合锹。 在需要替换其它工具头 时， 只需将螺钉 50松开， 从装配孔 30中取出， 将包塑装配 端 201从装配插槽 101中取出， 然后将需要的带有包塑装配 端的其它工具头， 如但不限于除草锹， 各型方锹、 尖锹、 三 齿叉、 四齿叉等， 按照前面描述的方法固定到工具柄的装配 插槽内即可。
图 4为本发明中又一种可替换工具头的多用途组合工具 的装配分解示意图。 图 3中的组合工具是对图 1中组合工具 的改进。 除了图 1中示出的结构外， 图 4中的组合工具在工 具头 20包塑装配端 201和装配插槽 101配合部位还带有前 盖 60和后盖 80， 所述的前盖 60、 后盖 80、 装配插槽 101壁 和工具头包塑装配端 201各带有至少两个相互对准的装配孔 30, 在前盖 60上的装配孔 30为预置的沉头镙孔， 后盖 80 上的装配孔 30为预置的镙钉自锁孔， 紧固镙钉 50穿过所述 的装配孔 30 旋紧固定。 这种紧固方法使得镙钉紧固时不会 产生因加力位移。
所述的前盖 60和后盖 80的形状设计成装配完成时使组 合工具具有宽且防滑的肩部 70， 如图 5示， 从而使操作者踩 挖时舒适省力。
图 6为图 5中可替换工具头的多用途组合工具从一角度 观察得到的防滑肩部立体示意图。 如图 6所示， 装配完成时 组合工具防滑的肩部 70优选带有多个具有防滑纹路的筋条。 带有防滑紋路筋条的前盖 60和后盖 80优选采用橡胶或塑料 注塑成型， 但并不局限于此。
装配插槽 101和柄体 10在使用金属柄时， 可整体焊接。 若使用由塑料、 含玻璃纤维成份的塑料、 含碳纤维的塑料或 木质材料等制成的柄， 装配插槽 101和柄体 10可做成分离 的， 使用时需要将装配插槽 101 和柄体 10连接固定。 图 7 为本发明中可替换工具头的多用途组合工具装配插槽 101与 柄体 10装配固定示意图。 装配插槽上部有安装库 40， 把装 工具头的柄端插入安装库 40， 置入穿心铆钉 90固定。
基于对本发明优选实施方式的描述， 应该清楚， 由所附 的权利要求书所限定的本发明并不仅仅局限于上面说明书 中所阐述的特定细节， 未脱离本发明宗旨或范围的对本发明 的许多显而易见的改变同样可能达到本发明的目的。
