本发明涉及一种与摆式工具的输出轴相连的工作头， 以及当工作头与摆式 工具不适配时所采用的转接器。 背景技术

第一类： 以德国 FEIN公司生产的型号为 MSx 636 II和 MSe 636 II等产品 为代表的摆式工具， 工作头 （如锯片）或转接器与摆式工具的输出轴之间采用 摩擦阻力固定（紧固件)，工作头的安装接口或转接器的转接接口上设一中心孔 (如圆孔） 即可与摆式工具的输出轴相连接固定， 这类工作头或转接器的特点 是安装接口只设中心孔不设止转限位镂空或凹陷， 中心孔可以是圆孔， 也可以 是正多边形孔等；
第二类： 以德国 FEIN公司生产的型号为 set START和 set SELECT等 MULTIMASTER产品为代表的摆式工具 （如 ZL 01143111. 3)，提供了一种用 来将一刀具固定在驱动轴上的刀夹，具有一连接孔，它做在刀具上或驱动轴上， 并与一相应成型的、 在两个元件中的另一个上的做的凸起的连接段共同作用， 以便形成形锁合的连接， 用以在驱动轴和刀具之间传递扭矩， 其中连接孔做的 相对于一穿过连接孔的中心线旋转对称， 并且连接孔具有至少三个向外的倒圆 的尖端， 并且每两个尖端通过一向中心线前进的曲线段相互连接。 工作头 （如 锯片） 或转接器与摆式工具的输出轴之间采用限位固定， 工作头的安装接口或 转接器的转接接口上设一中心孔 （如圆孔）及与中心孔相连的连接段， 即可与 相应的摆式工具的输出轴上的限位块相限位连接固定， 这类工作头或转接器的 特点是安装接口上设一中心孔及与中心孔相连的连接段或转接段， 中心孔及与 中心孔相连的连接段或转接段是一体的；
第三类： 以德国 BOSCH公司生产的型号为 PMF 180E为代表的摆式工具 (如申请号 200580035853. 3)， 具有一个定心元件及至少一共形锁合工具， 用 于将一个可轴向插套上的刀具固定在手持式工具机的可被振荡的驱动的驱动轴 上， 其中， 定心元件被设置用于刀具相对驱动轴的定心及形锁合元件被设置用 于确定刀具相对驱动轴的转动位置。 工作头 （如锯片）与摆式工具的输出轴之 间采用限位固定， 工作头的安装接口上设一中心孔（如圆孔）及中心孔外侧的 外镂空区域， 即可与相应的摆式工具输出轴上沿轴线的周向均布的限位柱相限 位连接固定， 这类工作头的特点是安装接口设一中心孔（如圆孔）及中心孔外 侧的外镂空区域， 中心孔（如圆孔） 与中心孔外侧的外镂空区域是孤立的； 同 样， 转接器与摆式工具的输出轴之间也采用限位固定， 转接器的转接接口上设 一中心孔（如圆孔）及中心孔外侧的外凹陷区域， 即可与相应的摆式工具输出 轴上沿轴线的周向均布的限位柱相限位连接固定， 这类转接器的特点是转接接 口设一中心孔（如圆孔）及中心孔外侧的外凹陷区域， 中心孔 （如圆孔）与中 心孔外侧的外镂空区域是孤立的。
连接固定方式为上述第二类和第三类的工作头或转接器可用于第一类摆式 工具，但连接固定方式为第二类的工作头或转接器不能用于第三类摆式工具， 连接固定方式为第三类的工作头或转接器不能用于第二类摆式工具。 这样， 由 于接口不统一给使用者带来诸多不便。 特别是第三类的工作头的安装接口上中 心孔 （如圆孔） 与中心孔外侧的外镂空区域是各自孤立的， 转接器的安装接口 上中心孔 （如圆孔） 与中心孔外侧的外凹陷区域也是各自孤立的， 制造工作头 或转接器的模具上与其相对应部分也是各自孤立的， 模具整体性差、 结构强度 低、 加工精度低， 那么工作头上的安装接口和转接器上的转接接口加工精度都 难保证， 制造成本高、 通用性差。 发明的公开
本发明的目的在于：对现有的用于摆式工具的工作头进行改进，提供一种通 用性更好工作头， 且工作头的制造模具整体性好、 结构强度高。 本发明的所有 连接段都是与中心孔相连通的， 但连接段可以与外镂空区域可以是相连通的， 也可以是不相连通的。
其次本发明提供一种转接器，其通用性更好且其制模具整体性好、结构强度 高。 本发明的所有转接段都是与转接中心孔相连通的， 但转接段可以与转接外 凹陷区域可以是相连通的， 也可以是不相连通的。
本发明的工作头是通过以下技术方案来实现的：
一种摆式工具工作头， 摆式工具的输出轴环绕其轴线振动驱动并具有固 定工作头的固定件，其中， 工作头上设有一个安装接口，用于与摆式工具上的固 定件相连接固定，工作头还设有与安装接口相连接为的功能端，安装接口上设有 一中心孔和中心孔外侧的十二个外镂空区域， 其中， 十二个外镂空区域中可插 入摆式工具输出轴上沿轴线的周向均布的十二根限位柱， 同时工作头的安装接 口上设置有至少一个与中心孔相连的连接段， 使中心孔与其中至少一个外镂空 区域相连通， 连接段为开设在安装接口上的凹槽或者通孔， 且中心孔与连接段 形成的镂空面中可插入摆式工具输出轴上一个限位块。 这样工作头的安装接口 上与中心孔孤立的外镂空区域数量就减少了， 制造这种工作头的模具整体性比 较好、 结构强度也比较高。 而且当工作头上的镂空区域与限位柱不相配， 或者 没有限位柱的情况下， 依然可以通过连接段的镂空面与摆式工具上的限位块相 配， 以此将摆式工具与工作头连接。
本发明的优点在于： 工作头的制造成本低且通用性更好， 即既可用于第三 类摆式工具， 又可用于第一、 二类摆式工具。
在本发明中， 工作头上的功能端可以是锯切器具或磨具或刃具或抛光器具 等， 则工作头可以是锯切器具、 磨具、 刃具和抛光器具。 如工作头为锯切器具， 可以是带有锯齿的锯切器具， 通过配置一定的齿形和材质能锯切木材、 塑料和 金属等材质； 也可以是附有硬质材料的锯切器具， 通过配置一定磨粒粒度和材 质的硬质合金或金刚石颗粒能锯切石材和混凝土等材质； 也可以是具有一定形 状和功能的刀刃具等。
在本发明中， 所述的工作头的安装接口上设置有至少四个均布的与中心孔 相连的连接段， 中心孔与连接段形成的镂空面中可插入摆式工具输出轴上至少 四个均布的限位块。这种工作头的安装接口可以装配到以德国 FEIN公司生产的 型号为 set START和 set SELECT等产品为代表的摆式工具输出轴上， 该摆式工 具输出轴上有四个与连接段形状相应的限位块， 工作头 （如锯片） 与摆式工具 的输出轴之间采用限位固定。
在本发明中，工作头的安装接口上至少有一个与中心孔相连的连接段与二 或三个相邻的外镂空区域之间相连接。 这是为了减少中心孔外孤立的镂空区域 数量， 提高制造这种工作头的模具整体性和结构强度。
在本发明中，工作头的安装接口上设置有四个均布的与中心孔相连的连接 段， 使中心孔与四个或八个或十二个外镂空区域相连通。 中心孔外孤立的镂空 区域数量就大大减少， 甚至没有中心孔外孤立的镂空区域。
在本发明中，工作头的安装接口上设置有八个均布的与中心孔相连的连接 段， 其中四个连接段按每个连接段与一个相邻的外镂空区域之间相连接的方式 连接， 另外四个连接段按每个连接段与二个相邻的外镂空区域之间相连接的方 式连接， 两种连接方式交错分布， 且中心孔与连接段形成的镂空面中可插入摆 式工具输出轴上八个均布的限位块。 中心孔外没有孤立的镂空区域， 制造这种 工作头的模具整体性和结构强度都较好。 由于工作头的安装接口上设置有八个 均布的与中心孔相连的连接段，这种工作头可以八种不同角度装配到德国 FEIN 公司生产的型号为 set START和 set SELECT等产品上， 这类产品输出轴上有四 个与连接段形状相应的限位块。 这是上述方案的进一步的优化。
在本发明中， 工作头的安装接口上设置有八个均布的与中心孔相连的连接 段， 其中四个连接段按每个连接段只与中心孔相连接而不与任何一个外镂空区 域之间相连接的方式连接， 另外四个连接段按每个连接段与二个相邻的外镂空 区域之间相连接的方式连接， 两种连接方式交错分布， 且中心孔与连接段形成 的镂空面中可插入摆式工具输出轴上八个均布的限位块。 中心孔外只有四个孤 立的镂空区域， 制造这种工作头的模具整体性和结构强度都较好， 工作头的结 构强度也都较好。 由于工作头的安装接口上设置有八个均布的与中心孔相连的 连接段， 这种工作头可以有八种不同角度装配到德国 FEIN公司生产的型号为 set START和 set SELECT等产品上， 这类产品输出轴上有四个与连接段形状相 应的限位块。 这也是上述方案的进一步的优化。
在上述方案中， 工作头上安装接口的中心孔形状是可以的圆形， 也可以是 正多边形、 8星形、 12星形等； 工作头上安装接口的连接段形状是与摆式工具 输出轴上限位块的截面形状相应的， 中心孔与连接段形成的镂空面中可插入摆 式工具输出轴上的限位块， 即中心孔与连接段形成的镂空面能包容限位块横截 面， 连接段既可以做成与限位块起限位作用， 也可以做成不与限位块起限位作 用， 即把镂空面与限位块的间隙取大些； 工作头上安装接口的中心孔外侧的外 镂空区域形状是与摆式工具输出轴上的限位柱形状相应的， 外镂空区域中可插 入摆式工具输出轴上的限位柱， 即外镂空区域能包容限位柱截面， 连接段既可 以做成与限位柱起限位作用， 也可以做成不与限位柱起限位作用， 即把镂空面 与限位块的间隙取大些； 限位柱截面可以是圆形、 椭圆形、 长圆形和矩形等形 状， 因此工作头的安装接口上的外镂空区域也可以是圆形、 椭圆形、 长圆形和 矩形等形状。
其次，本发明的转接器是通过以下技术方案来实现的：
一种转接器， 用于将工作头的安装接口的形状与摆式工具输出轴上的限位 柱或限位块的形状不相匹配的工作头固定到摆式工具的输出轴上，在转接器的 第一面上设有与摆式工具输出轴相连接固定的转接接口，转接接口上设有一转 接中心孔和转接中心孔外侧的十二个转接外凹陷区域， 在转接器的第二面上可 固定工作头， 其特征在于： 所述的转接器的转接接口上设置有至少一个与转接 中心孔相连的转接段， 所述的转接段开设在转接接口上的凹槽或者通孔， 使转 接中心孔与其中至少一个转接外凹陷区域相连通， 且转接中心孔与连接段形成 的凹陷面中可插入摆式工具输出轴上一个限位块。 这样转接器的转接接口上与 中心孔孤立的的转接外凹陷区域数量就减少了， 制造这种转接器的模具整体性 比较好、 结构强度也比较高。 当然这种转接器可以装配到第二类摆式工具的输 出轴上， 输出轴上的有一与连接段形状相应的限位块。
本发明的优点在于： 转接器的制造成本低且通用性更好， 即既可用于第三 类摆式工具， 又可用于第一、 二类摆式工具。
在本发明中，转接器的安装接口上至少有一个与转接中心孔相连的转接段 与二或三个相邻的转接外凹陷区域之间相连接。 这是为了减少转接中心孔外孤 立的凹陷区域数量， 提高制造这种转接器的模具整体性和结构强度。
在本发明中，转接器的转接接口上设置有四个均布的与中心孔相连的转接 段， 使转接中心孔与四个或八个或十二个转接外凹陷区域相连通。 转接中心孔 外孤立的转接外凹陷区域数量就大大减少， 甚至没有转接中心孔外孤立的转接 外凹陷区域。
在本发明中，转接器的转接接口上设置有八个均布的与转接中心孔相连的 转接段， 其中四个转接段按每个转接段与一个相邻的转接外凹陷区域之间相连 接的方式连接， 另外四个转接段按每个转接段与二个相邻的转接外凹陷区域之 间相连接的方式连接， 两种连接方式交错分布， 且转接中心孔与转接段形成的 凹陷面中可插入摆式工具输出轴上八个均布的限位块。 转接中心孔外没有孤立 的转接外凹陷区域， 制造这种工作头的模具整体性和结构强度都较好。 由于转 接器的转接接口上设置有八个均布的与转接中心孔相连的转接段， 这种转接器 可以有八种不同角度装配到德国 FEIN公司生产的型号为 set START和 set SELECT等产品上， 这类产品输出轴上有四个与转接段形状相应的限位块。这是 上述方案的进一步的优化。
在本发明中， 转接器的转接接口上设置有八个均布的与转接中心孔相连的 转接段， 其中四个转接段按每个转接段只与转接中心孔相连接而不与任何一个 转接外凹陷区域之间相连接的方式连接， 另外四个转接段按每个转接段与二个 相邻的转接外凹陷区域之间相连接的方式连接， 两种连接方式交错分布， 且转 接中心孔与转接段形成的凹陷面中可插入摆式工具输出轴上八个均布的限位 块。 转接中心孔外只有四个孤立的转接外凹陷区域， 制造这种转接器的模具整 体性和结构强度都较好， 转接器的结构强度也都较好。 由于转接器的转接接口 上设置有八个均布的与转接中心孔相连的转接段， 这种转接器可以有八种不同 角度装配到德国 FEIN公司生产的型号为 set START和 set SELECT等产品上， 这类产品输出轴上有四个与转接段形状相应的限位块。 这也是上述方案的进一 步的优化。
在上述方案中， 转接器上转接接口的转接中心孔形状是可以的圆形， 也可 以是正多边形、 8星形、 12星形等； 转接器上转接接口的转接段形状是与摆式 工具输出轴上限位块的截面形状相应的， 转接中心孔与转接段形成的凹陷面中 可插入摆式工具输出轴上的限位块， 即中心孔与转接段形成的凹陷面能包容限 位块横截面， 转接器上转接接口的转接中心孔外侧的转接外凹陷区域形状是与 摆式工具输出轴上的限位柱形状相应的， 转接外凹陷区域中可插入摆式工具输 出轴上的限位柱， 即转接外凹陷区域能包容限位柱截面， 转接段既可以做成与 限位柱起限位作用， 也可以做成不与限位柱起限位作用， 即把凹陷面与限位块 的间隙取大些； 限位柱截面可以是圆形、 椭圆形、 长圆形和矩形等形状， 因此 转接器的转接接口上的转接外凹陷区域也可以是圆形、 椭圆形、 长圆形和矩形 等形状 附图说明

实现本发明的最佳方法
下面通过实施例， 并结合附图， 对本发明技术方案作进一步具体的说明。 实施例：
如图 2所示： 摆式工具 10输出轴 12环绕其轴线 14以 0. 6〜7° 的小回转 角和每分钟 5000〜25000次的高频率运行。
图 2中的工作头 20以安装接口的纵剖面示出。 输出轴 12上具有固定工作 头 20的固定件，其中， 例如它可以是一个螺纹盲孔与螺钉 30， 将工作头 20穿 过工作头 20上的安装接口固定在输出轴 12上。
不言而喻， 可以用其它形式的固定件将工作头 20与输出轴 12连接。 例如 也可以是内六角等紧固件。
在图 1中， 摆式工具工作头 20上设有一个用于与摆式工具上的固定件相 连接固定的安装接口，工作头 20还设有与安装接口相连接的功能端 26， 安装接 口上设有一中心孔 21和中心孔 21外侧的十二个外凹陷区域 22， 其中， 十二个 外凹陷区域 22 中可插入摆式工具输出轴上沿轴线的周向均布的十二根限位柱 15， 安装接口上设置有一个与中心孔 21相连的连接段 23， 使中心孔 21与其中 一个外凹陷区域 22相连通，且中心孔 21与连接段 23形成的镂空面中可插入摆 式工具输出轴上一个限位块 16。这种工作头能十二个角度装配到输出轴的相应 部位上有均布的十二根限位柱的摆式工具上； 同理， 这种工作头能十二个角度 装配到以下摆式工具上： 输出轴的相应部位上有均布的一根或二根或三根或四 根或六根限位柱的摆式工具及限位柱按均布十二根方式排列但有几个限位柱位 置未设限位柱的； 这种工作头能以一个特定角度装配到输出轴相应部位上有一 个限位块的摆式工具上； 这种工作头能以任意角度装配到输出轴相应部位上无 限位柱和无限位块的摆式工具上。
在图 3中， 工作头 20的安装接口上设置有四个均布的与中心孔 21相连的 连接段 23， 中心孔 21与连接段 23形成的镂空面中可插入摆式工具输出轴上四 个均布的限位块 16。这种工作头能以四个特定角度装配到输出轴相应部位上有 一个或二个或四个限位块或限位块按均布四个限位块方式排列但有几个限位块 位置未设限位块的的摆式工具上。
在图 4、 图 5中， 工作头 20的安装接口上有一个与中心孔 21相连的连接 段 23分别与二个或三个相邻的外镂空区域 22之间相连接。
图 6、 图 7、 图 8、 图 9和图 10分别示出进一步优化的实施方式的工作头。 在图 6、图 7和图 8中，工作头 20的安装接口上设置有四个均布的与中心孔 21 相连的连接段 23， 使中心孔 21与四个或八个或十二个外镂空区域 22相连通， 且中心孔 21与连接段 23形成的镂空面中可插入摆式工具输出轴上四个均布的 限位块 15。 中心孔外孤立的镂空区域数量就大大减少， 甚至没有中心孔外孤立 的镂空区域。 提高了制造这种工作头的模具整体性和结构强度。
在图 9和图 10中， 工作头 20的安装接口上设置有八个均布的与中心孔 21相连的连接段 23，其中四个连接段 23按每个连接段 23与一个相邻的外镂空 区域 22之间可连接也可不连接，另外四个连接段 23按每个连接段 23与二个相 邻的外镂空区域 22之间相连接的方式连接，两种连接方式交错分布，且中心孔 21与连接段 23形成的镂空面中可插入摆式工具输出轴上八个均布的限位块 16。 从图中可以知道， 制造这种工作头的模具整体性和结构强度都较好， 工作头的 结构强度也都较好。 这种工作头能以八个特定角度装配到输出轴相应部位上有 一个或二个或四个或八个限位块的摆式工具上或限位块按均布八个限位块方式 排列但有几个限位块位置未设限位块的的摆式工具上。 当然， 这种工作头能以 十二个特定角度装配到输出轴相应部位上有均布的十二根限位柱的摆式工具 上； 这种工作头也可以任意角度装配到输出轴无限位柱和无限位块的摆式工具 上。 工作头可多角度装配到摆式工具上， 方便操作， 减少工作的劳动强度。
工作头上安装接口的中心孔形状是可以的圆形， 也可以是正多边形、 8 星 形、 12星形等， 优选圆形和正多边形； 工作头上安装接口的连接段形状是与摆 式工具输出轴上限位块的截面形状相应的， 中心孔与连接段形成的镂空面中可 插入摆式工具输出轴上的限位块， 即中心孔与连接段形成的镂空面能包容限位 块横截面， 连接段既可以做成与限位块起限位作用， 也可以做成不与限位块起 限位作用； 工作头上安装接口的中心孔外侧的外镂空区域形状是与摆式工具输 出轴上的限位柱形状相应的，外镂空区域中可插入摆式工具输出轴上的限位柱， 即外镂空区域能包容限位柱截面， 连接段既可以做成与限位柱起限位作用， 也 可以做成不与限位柱起限位作用。 限位柱截面可以是圆形、 椭圆形、 长圆形和 矩形等形状， 因此工作头的安装接口上的外镂空区域也可以是圆形、 椭圆形、 长圆形和矩形等形状， 优选矩形。 以便与与截面为圆形、 椭圆形、 长圆形和矩 形等形状的限位柱配。
不言而喻， 安装接口的形状也可以在上述实施例的基础上进行简单变通， 对安装接口的一些部位进行镂空处理， 这也是业内技术人员都能设计的， 就不 叙述。
总而言之，本发明的工作头，能多角度装配到各类摆式工具中，方便操作， 减少工作的劳动强度。 同时制造这种工作头的模具整体性和结构强度都较好， 工作头的结构强度也都较好， 便与产品低成本、 高品质制造。
图 12中的转接器 40以安装接口的纵剖面示出。转接器 40装配到摆式工具 状态时的纵剖图，其中，示意出将安装接口的形状与摆式工具输出轴 12上的限 位柱 15或限位块 16的形状不相匹配的工作头 20a通过转接器 40固定到输出轴 12上，摆式工具的输出轴 12环绕其轴线振动驱动并具有固定工作头 20a和转接 器 40的固定件； 其中， 固定件可以是一个螺纹盲孔与螺钉 30， 固定件将工作 头 20a通过转接器 40安装固定在输出轴 12上。
不言而喻，可以用其它形式的固定件将工作头 20a、转接器 40与输出轴 12 连接。 例如也可以是内六角等紧固件。
在图 11中，转接器 40的第一面 45上设有一个用于与摆式工具输出轴 12 上的固定件相连接固定的转接接口， 转接接口上设有一转接中心孔 41 和转接 中心孔 41外侧的十二个转接外凹陷区域 42， 其中， 十二个转接外凹陷区域 42 中可插入摆式工具输出轴 12上沿轴线的周向均布的十二根限位柱 15， 转接器 40的安装接口上设置有一个与中心孔 41相连的转接段 43， 使转接中心孔 41 与其中至少一个转接外凹陷区域 42相连通，且转接中心孔 41与转接段 43形成 的凹陷面中可插入摆式工具输出轴 12上一个限位块 16。
这种转接器 40能十二个角度装配到输出轴 12的相应部位上有均布的十二 根限位柱 15的摆式工具上； 同理， 这种转接器 40能十二个角度装配到以下摆 式工具上:输出轴 12的相应部位上有均布的一根或二根或三根或四根或六根限 位柱 15的摆式工具及限位柱 15按均布十二根方式排列但有几个限位柱 15位置 未设限位柱 15的； 这种转接器能以一个特定角度装配到输出轴 12相应部位上 有一个限位块 16的摆式工具上；这种工作头能以任意角度装配到输出轴相应部 位上无限位柱 15和无限位块 16的摆式工具上。
图 13是图 11示出的转接器 40的后视图，在转接器 40的第二面设有凸起 的连接工作头段 47，图中以正六边形示意出凸起的连接工作头段 47， 以便与安 装接口形状与此相匹配的工作头 20a相连接固定。 连接工作段的形状可以多种 多样， 只要与工作头的安装接口形状相匹配即可。
在图 14、 图 15中， 转接器 40的转接接口上有一个与转接中心孔 41相连 的转接段 43分别与二个或三个相邻的转接外凹陷区域 42之间相连接。
图 16、 图 17、 图 18、 图 19和图 20分别示出进一步优化的实施方式的转 接器。
在图 16、 图 17和图 18中， 转接器 40的转接接口上设置有四个均布的与 转接中心孔 41相连的转接段 43，使转接中心孔 41与四个或八个或十二个外凹 陷区域 42相连通，且转接中心孔 41与转接段 43形成的凹陷面中可插入摆式工 具输出轴 12上四个均布的限位块 15。转接中心孔 41外孤立的转接外凹陷区域 42数量就大大减少， 甚至没有转接中心孔 41外孤立的转接外凹陷区域 42。 提 高了制造这种转接器的模具整体性和结构强度。
在图 19和图 20中，转接器 40的转接接口上设置有八个均布的与转接中心 孔 41相连的转接段 43， 其中四个转接段 43按每个转接段 43与一个相邻的转 接外凹陷区域 42之间可连接也可不连接，另外四个转接段 43按每个转接段 43 与二个相邻的转接外凹陷区域 42之间相连接的方式连接，两种连接方式交错分 布， 且转接中心孔 41与转接段 43形成的凹陷面中可插入摆式工具输出轴上八 个均布的限位块 16。从图中可以知道， 制造这种转接器的模具整体性和结构强 度都较好， 转接器的结构强度也都较好。 这种转接器能以八个特定角度装配到 输出轴相应部位上有一个或二个或四个或八个限位块的摆式工具上或限位块按 均布八个限位块方式排列但有几个限位块位置未设限位块的摆式工具上。当然， 这种转接器能以十二个特定角度装配到输出轴相应部位上有均布的十二根限位 柱的摆式工具上； 这种转接器也可以任意角度装配到输出轴相无限位柱和无限 位块的摆式工具上。 该转接器可多角度装配到摆式工具上， 方便操作， 减少工 作的劳动强度。
在图 21中 ，在转接器 40的第二面设有三个齿尖朝向工作头 20a凸起的齿 段 48，齿尖高出转接器 40与工作头 20a的装配面。 将转接器 40和工作头 20a 紧固到摆式工具的输出轴上时， 齿段 48与工作头 20a小面积接触， 齿段 48的 齿尖可部分嵌入到工作头 20a中， 提高连接强度。 同是对工作头 20a的安装接 口形状要求降低， 不必一一对应， 常规的工作头就能通过该转接器固定到摆式 工具的输出轴上， 方便操作者购买使用。
转接器上转接接口的中心孔形状可以是圆形， 也可以是正多边形、 8星形、 12星形等， 优选圆形和正多边形； 转接器上转接接口的连接段形状是与摆式工 具输出轴上限位块的截面形状相应的， 转接器与转接段形成的凹陷面中可 插入摆式工具输出轴上的限位块， 即转接中心孔与转接段形成的凹陷面能包容 限位块横截面， 转接段既可以做成与限位块起限位作用， 也可以做成不与限位 块起限位作用； 转接器上转接接口的中心孔外侧的外凹陷区域形状是与摆式工 具输出轴上的限位柱形状相应的， 外凹陷区域中可插入摆式工具输出轴上的限 位柱， 即外凹陷区域能包容限位柱截面， 转接段既可以做成与限位柱起限位作 用， 也可以做成不与限位柱起限位作用。 限位柱截面可以是圆形、 椭圆形、 长 圆形和矩形等形状，因此转接器的转接接口上的转接外凹陷区域也可以是圆形、 椭圆形、 长圆形和矩形等形状， 优选矩形。 以便与截面为圆形、 椭圆形、 长圆 形和矩形等形状的限位柱配。 另外， 转接外凹陷区域可以部分贯穿到转接器的 第二面。
不言而喻， 转接器的转接接口的形状也可以在上述实施例的基础上进行简 单变通， 对转接器的转接接口的一些部位进行凹陷处理， 这也是业内技术人员 都能设计的， 就不叙述。
