具体实施方式
以下结合附图和实施例对本申请进行介绍。
图1所示的作为实施例的修枝机100设置为供用户操作以切割各种灌木、绿篱等植被。为了方便说明本申请的技术方案，定义了图1中箭头所示的方向分别为：上、下、左、右、前和后。
本领域普通技术人员将理解，结合数量或条件使用的相对术语(例如，“约”，“大约”，“大体上”等)为包括所述值并且具有上下文所指示的含义(例如，该术语至少包括与特定值的测量相关的误差程度，与特定值相关的公差(例如制造，组装，使用)等)。这种术语也应被视为公开了由两个端点的绝对值限定的范围。相对术语可指代所指示的值的加或减一定百分比(例如1％，5％，10％或更多)。当然，未采用相对术语的数值，也应该被揭示为具有公差的特定值。
如图1至图4所示，修枝机100包括前端装置1、后端装置2以及连接杆组件3。其中，前端装置1包括用于输出动力的切割组件70和支撑切割组件70的前壳体20。后端装置2包括用于驱动切割组件70的马达30和支撑马达30的后壳体10。连接杆组件3连接前端装置1和后端装置2。示例性地，连接杆组件3包括沿第一轴线102方向延伸的连接杆60。修枝机100还包括供电装置40和传动组件50。其中，传动组件50设置为在马达30和切割组件70之间实现动力的传输。供电装置40设置为给马达30提供电能。本实施例中，供电装置40可以为直流的电源，例如电池包。当然，供电装置40也可以设置为交流电，如市电。
示例性地，后壳体10包括用于形成第一容纳空间111的容纳部11、用于供用户握持的主把手13以及用于连接供电装置40的结合部12。马达30和部分的传动组件50设置在容纳部11所形成的第一容纳空间111内。前壳体20设置在后壳体10的前侧，形成有第二容纳空间(图中未示)，设置为容纳部分传动组件50和部分的切割组件70。其中，切割组件70沿纵向轴线101延伸。本实施例中，前壳体20和后壳体10位于连接杆60的两端，设置为支撑连接杆60。在一些实施例中，主把手13设置为与后壳体10独立分开的结构。例如，主把手13独立套设在连接杆组件13上，即主把手13独立套设在连接杆60上。在 一些实施例中，连接杆60上直接形成有供用户握持的握持部，从而替代主把手13。可以理解为，不单独设置供用户握持的主把手13，而是利用原有的结构进行改进，从而形成握持部。
马达30设置在第一容纳空间111内，位于主把手13的后侧且位于结合部12的上侧。当供电装置40连接至结合部12后，在一个垂直于上下方向上的平面内，马达30在上述平面上的投影与供电装置40在上述平面上的投影有重叠。示例性地，马达30包括绕马达轴线301转动的马达轴31。本实施例中，马达30设置为电机。这样，马达30位置的合理布置能够提高修枝机100的整机的平衡性，提高用户体验。当然，马达30也可以选择设置在其他的位置，例如主把手13的前侧或者第二容纳空间内。
供电装置40可拆卸地连接至结合部12，设置为给马达30供电。示例性地，在前后方向上，结合部12位于主把手13的后侧。在一些实施例中，供电装置40沿第一方向可拆卸地连接至结合部12以为马达30供电。其中，第一方向平行于纵向轴线101方向。在一些实施例中，供电装置40沿第二方向可拆卸地连接至结合部12以为马达30供电。其中，第二方向与纵向轴线101方向相交。在一些实施例中，供电装置40沿第三方向可拆卸地连接至结合部12以为马达30供电。其中，第三方向与纵向轴线101方向倾斜相交。当然，当供电装置40沿第三方向可拆卸地连接至结合部12时，后壳体10上的结合部12需要适当改变，但并不影响后壳体10内，例如马达30的位置。需要理解的是，在一些实施例中，切割组件70的切割角度可调，上述的纵向轴线101应该理解为当切割组件70调节至与连接杆60平行或大致平行的状态时的，产生的纵向轴线101。
在一些实施例中，供电装置40包括一个电池包，电池包的额定输出电压大于或等于18V。示例性地，电池包的额定输出电压设置为56V。在另一些实施例中，供电装置40包括两个或两个以上的电池包。电池包例如可以为锂电池包，包括多个电性连接的电芯单元，电芯单元的数目决定了电池包的标称电压以及供电能力。本申请中，对于供电装置40的插入方向以及电池包的个数并不做限 制。在另一些实施例中，供电装置40也可以设置为内置在后壳体10内的电池包。
如图2所示，修枝机100还包括：电路板组件81、散热板82以及风扇83。其中，电路板组件81与马达30构成电性连接，散热板82设置为给电路板组件81进行散热，风扇83设置为产生散热气流。电路板组件81、散热板82和风扇83均设置在第一容纳空间111内。后壳体10还形成有连通后壳体10内外的气流入口841和气流出口842，风扇83转动时能产生自气流入口841进入后壳体10并流经马达30的散热气流，从而对马达30进行散热。
传动组件50设置为在马达30和切割组件70之间实现动力的传输。本实施例中，传动组件50包括第一传动装置51和第二传动装置52以及传动轴53。其中，第一传动装置51与马达30相连且设置在后壳体10所形成的第一容纳空间111内。第二传动装置52设置在前壳体20所形成的第二容纳空间内。传动轴53沿第一轴线102方向延伸，设置为在第一传动装置51和第二传动装置52之间传输动力。其中，前壳体20也可以理解为第二传动装置52的箱体。
示例性地，第一传动装置51包括第一传动齿511和第二传动齿512。其中，第一传动齿511连接马达30的马达轴31，且由马达轴31驱动绕马达轴线301转动。第二传动齿512由第一传动齿511驱动绕第一轴线102转动。其中马达轴线301平行于第一轴线102。本实施例中，第一传动齿511和第二传动齿512设置为斜齿轮。这样，当修枝机100在运行时，第一传动装置51的噪音更小，传动更加平稳。这样，采用一级传动，能够大大缩短传动组件50在上下方向上的高度，从而使得用户在操作修枝机100进行工作时，整机的重心更加接近连接杆60，以提高用户的操作手感。
第二传动装置52设置在前壳体20内，设置为将马达30传递过来的转动转换成切割组件70的往复运动。第二传动装置52包括第一锥齿轮521、第二锥齿轮522以及偏心轴525。其中，第一锥齿轮521连接传动轴53，由传动轴53驱动绕第一轴线102转动。第二锥齿轮522由第一锥齿轮521驱动绕垂直于第 一轴线102的第二轴线103转动。第二锥齿轮522驱动偏心轴525绕第二轴线103同步转动。本实施例中，第一锥齿轮521具有第一锥面5211，第二轴线103到第一锥面5211的距离小于等于18mm。示例性地，第二轴线103到第一锥面5211的距离小于等于15mm。示例性地，第二轴线103到第一锥面5211的距离小于等于12mm。
偏心轴525上还形成有第一偏心轮部523和第二偏心轮部524。第一偏心轮部523和第二偏心轮部524均能以第二轴线103为轴转动。示例性地，第一偏心轮部523设置为与第一刀片71配合，第二偏心轮部524设置为与第二刀片72配合。本实施例中，第一偏心轮部523和第二偏心轮部524的圆心错开，第一偏心轮部523的圆心和第二偏心轮部524的圆心在一个平行于第一轴线102的平面上的投影间隔一定的距离。这样，第二锥齿轮522驱动第一偏心轮部523和第二偏心轮部524转动，进而使得第一刀片71和第二刀片72在沿纵向轴线101方向上产生相对运动。
本实施例中，传动组件50未作为一个整体，而是拆分为布置在修枝机100后侧的第一传动装置51和布置在修枝机100前侧的第二传动装置52。这样，将传动组件50的重量均匀分布在修枝机100的前后方向上，能够有效地提高整机的平衡性，提高用户的使用体验。另一方面，本申请中，第二传动装置52采用一级齿轮传动，能够有效地缩小传动组件50的体积，减轻整机的重量。
在一些实施例中，前壳体20上还形成有连通第二容纳空间的第一注油口22，第一注油口22在上下方向上位于第一锥齿轮521与第二锥齿轮522的啮合处。用户能够通过第一注油口22向前壳体20内的第二传动装置51注入润滑油，从而对传动组件进行润滑，可以有效降低传动组件的磨损，从而延长传动组件的使用寿命。这样，用户向前壳体20内注入的润滑油，在第一锥齿轮521和第二锥齿轮522的作用下，润滑油被快速涂抹在第一锥齿轮521和第二锥齿轮522上，具有较好的润滑效果，同时还能够避免大量的润滑油飞溅在前壳体20的内壁上。本实施例中，还包括第二注油口23，设置为给切割组件70提供润滑油。 第二注油口23的位置为常规位置，本申请中就不赘述了。
本实施例中，连接杆60连接前壳体20和后壳体10。连接杆60沿第一轴线102方向延伸形成有第一端61和第二端62。其中，连接杆60的第一端61由前壳体20支撑，即连接杆60的第一端61固定连接至前壳体20。连接杆60的第二端62由设置后壳体10支撑。示例性地，连接杆60的第二端62由设置在后壳体10内的用于容纳第一传动装置51的齿轮箱513支撑。即连接杆60的第二端62固定连接至后壳体10。示例性地，前壳体20形成或连接有第一连接端21，设置为连接连接杆60的第一端61。齿轮箱513的前端面5131形成或连接有第二连接端5132，设置为连接连接杆60的第二端62。本实施例中，前壳体20的第一连接端21套设在连接杆60的第一端61上，采用螺钉紧固的方式进行装配。齿轮箱513的第二连接端5132套设在连接杆60的第二端62，采用紧配合的方式进行固定安装。当然，需要理解的是，连接杆60与前壳体20以及后壳体10之间的连接方式以及连接位置，本领域的技术人员可以根据实际应用情况进行设计，本申请中对此并不做限制。
在一些实施例中，参见图5和图6所示，连接杆60沿第一轴线102方向延伸且连接杆60为中空结构。可以理解，连接杆60形成有沿第一轴线102方向延伸的第一通孔63，传动轴53沿第一轴线102方向设置在上述的第一通孔63中。在一些实施例中，传动轴53也可以设置为中空结构。本实施例中，连接杆60包括碳纤维材料，连接杆60的密度与抗拉强度的比值大于或等于4.5kg/(m3·MPa)且小于或等于15kg/(m3·MPa)。连接杆60采用异形模制工艺制造。当然，连接杆60也可以采用碳纤维材料和塑料混合的材料制成。
这样，该修枝机100的连接杆60的强度能满足前壳体20以及切割组件70的需求，同时可以降低修枝机100的前部的重量，从而能够提高用户的工作效率且有利于改善修枝机100的重心的位置。采用上述的材料能够减小修枝机100的重量，使得用户在操作时更加省力。本实施例中，连接杆60设置为圆形管状，可以理解，连接杆60也可以设置为方形管状或其他形状。
在一些实施例中，连接杆组件3还包括在连接杆60和驱动轴63之间的多个限位件64。示例性地，限位件64套设在驱动轴53上，设置为实现连接杆60与驱动轴53在垂直于第一轴线102的平面上的限位。当然，限位件64也可以是直接连接至连接杆60的内壁上。这样，当传动轴53安装至连接杆60内后，在多个限位件64的作用下，传动轴53和连接杆60在保证较高的同轴度的同时，还具有较高的稳定性，保证用户在操作修枝机100进行多角度切割时，传动轴53均能很好地固定在连接杆60内，且保证较高的同轴度。
参见图3和图4所示，切割组件70设置为执行修枝机100的切割功能。切割组件70的一部分容纳在前壳体20所形成的第二容纳空间内，另一部分沿纵向轴线101方向伸出至第二容纳空间之外。本实施例中，切割组件70包括由马达30驱动的第一刀片71、能相对第一刀片71沿纵向轴线101方向往复运动的第二刀片72以及刀片支架73和保护齿74。示例性地，切割组件70沿纵向轴线101方向延伸。第一刀片71以及第二刀片72上均布置有多个切割齿711，多个切割齿711在沿纵向轴线101方向上等间距分布。保护齿74设置为避免用户的腿、胳膊伸入至相邻的两个切割齿711之间。示例性地，刀片支架73由碳纤维材料和玻璃纤维材料混合而成。
在一些实施例中，本申请的中前壳体20还适用于图7和图8中所示的切割组件70a。与图1中的切割组件70不同的是，本实施例中的切割组件70a在需要更换时，无需打开前壳体20即可更换刀片，更加方便。
示例性地，当用户需要将切割组件70a上的第一刀片71a进行更换时，首先松开并移出第三紧固件73a上的螺钉，并沿第四方向移动第三紧固件73a，以使第三紧固件73a能够从前壳体20中移出。当第三紧固件73a移出后，沿第四方向移动第一刀片71a，当第一刀片71a上的第一孔712a移动至第四紧固件74a处时，第一刀片71a能向上移动脱离第三紧固件73a。上述为第一刀片71a取出的过程，可以理解第二刀片72a的取出步骤以及它们的安装步骤也为本领域的技术人员所熟悉，此处不再赘述。这样，本申请中的修枝机100既可以采用两 种形式的切割组件。示例性地，一种切割组件的在安装和拆卸时需要首先打开前壳体20，然后再进行操作。另一种切割组件在更换刀片时间无需打开前壳体20，更加方便快捷。
参见图9所示，本实施例中，在纵向轴线101上，修枝机100的切割组件70的前端到后壳体10的后端的距离L1大于或等于1.1m且小于或等于2.2m。示例性地，修枝机100的切割组件70的前端到后壳体10的后端的距离L1大于或等于0.9m且小于或等于1.8m。示例性地，修枝机100的切割组件70的前端到后壳体10的后端的距离L1大于或等于0.7m，且小于或等于1.5m。这样，采用上述设置的修枝机，一方面能够双手操作，更加便携和安全；另一方面，采用连杆结构，使得修枝机具有较佳的切割高度，更有利于满足用户不同的切割需求。
参见图9和图10所示，修枝机100的重心G在前后方向上位于主把手13和辅助把手14之间。示例性地，当用户进行平切时(如图9所示)，用户的一只手握持主把手13、另一只手握持主握持部141，此时，在修枝机100的重心G在垂直于上下方向的平面上的投影与第一轴线102在上述平面上的投影的距离比较小，几乎为零。当用户进行平切时(如图10所示)，用户的一只手握持主把手13、另一只手握持侧握持部142，这时用户握持侧握持部142的手能够尽可能的靠近连接部143，从而使得修枝机100的重心G尽可能的靠近第一轴线102，从而修枝机100不会在左右方向上发生倾斜，进而实现更稳定的操作。本实施例中，修枝机100的重心G到第一轴线102的距离L4大于等于0且小于等于30mm。示例性地，修枝机100的重心G到第一轴线102的距离L4大于等于0且小于等于20mm。示例性地，修枝机100的重心G到第一轴线102的距离L4大于等于0且小于等于10mm。本申请中这样设置修枝机的重心，能够保证整机的平衡性，降低用户在使用时的疲劳感。
参见图2和图12所示，修枝机100还包括在第一轴线102方向位于主把手13前侧的辅助把手14。用户在操作修枝机100进行切割操作时，可以双手同时 握持辅助把手14和主把手13从而实现更稳定的操作。本实施例中，主把手13和马达30设置在辅助把手14的同侧，辅助把手14相对主把手13更靠近切割组件70。辅助把手14还与主把手13在第一轴线102方向上间隔开一定的距离，这样使得用户能够更稳定的控制修枝机100。
示例性地，辅助把手14设置为D型把手，且具有多个握持部，能够满足用户不同方向的切割需求，且操作轻松，不易疲劳。本实施例中，辅助把手14包括主握持部141、侧握持部142和连接部143。其中，主握持部141和侧握持部142分别设置为供用户在进行平切或侧切时的另一只手握持。示例性地，主握持部141还沿垂直于第一轴线102方向延伸，主握持部141在左右方向上横跨修枝机100。这样，当用户进行平切时，用户可以一只手握持主把手13、另一只手握持辅助把手14的主握持部141，从而实现稳定的切割。侧握持部142的数目为2，两个侧握持部142分别设置在主握持部141的两侧，主握持部141连接两个侧握持部142，侧握持部142的延伸方向与主握持部141的延伸方向相互垂直，侧握持部142的延伸方向还与第一轴线102倾斜相交。连接部143分别与两个侧握持部142连接，设置为将辅助把手14固定安装至修枝机100。示例性地，在一个垂直于第一轴线102的平面内，辅助把手14在平面的投影围绕形成D型区域，连接杆60在上述平面内的投影至少部分位于D型区域内。
在一些实施例中，辅助把手14通过连接部143固定至安装至连接杆60。在一些实施例中，辅助把手14通过连接部143固定安装至前壳体20的第一连接端21。在一些实施例中，辅助把手14通过连接部143同时与连接杆60和前壳体20的第一连接端21固定连接。本实施例中，辅助把手14的连接部143通过第一锁紧装置145与连接杆60连接，且通过第二锁紧装置146与前壳体20的第一连接端21连接。参见图11所示，前壳体20的第一连接端21形成有第一端面211，辅助把手14到第一端面211所在的平面的距离L5大于等于0且小于等于90mm。示例性地，辅助把手14到第一端面211所在的平面的距离L5大于等于0且小于等于70mm。示例性地，辅助把手14到第一端面211所在的 平面的距离L5大于等于0且小于等于50mm。示例性地，辅助把手14到第一端面211所在的平面的距离L5大于等于0且小于等于20mm。应当理解，距离L5是指辅助把手14的靠近第一端面211的一侧到第一端面211的距离。
示例性地，连接部143形成有一能够容纳连接杆60的凹槽1431。在装配过程中，首先将连接杆60放置在第二锁紧装置146中，然后再将它们放置在上述的凹槽1431中，最后通过第一紧固件1461固定安装至前壳体20的第一连接端21上，同时，通过第二紧固件1462将第二锁紧装置146、第一锁紧装置145以及辅助把手14的连接部143在上下方向上进行固定。这样，通过第一锁紧装置145和第二锁紧装置146将辅助把手14固定安装至连接杆60的同时，还将辅助把手14固定至前壳体20的第一连接端21，实现辅助把手14在各个方向上的限位，提高了辅助把手14的稳定性，提高整机的安全性能。
修枝机100还包括操作组件，设置为供用户操作以控制修枝机100的状态。参见图1所示，操作组件至少包括第一开关131和第二开关144。第一开关131具有释放状态和触发状态，同样地，第二开关144也具有释放状态和触发状态。用户能够操作第一开关131和第二开关144在释放状态和触发状态之间切换。修枝机100还包括控制装置，当第一开关131和第二开关144均处于触发状态时，控制装置控制马达30启动。本实施例中，第一开关131设置为扳机。需要理解的是，第一开关131只是一个外部的构件，其应该还连接有电路组件，电路组件设置在主把手13所形成的空间内。
参见图10所示，在前后方向上，第一开关131到切割组件70的第一切割齿7111的距离L2大于等于0.12m且小于等于1000mm。示例性地，其中，切割组件70的第一切割齿7111可能是第一刀片71上的位于最后端的切割齿，也可能是第二刀片72上的位于最后端的切割齿。示例性地，在前后方向上，第一开关131到切割组件70的第一切割齿7111的距离L2大于等于0.2m，且小于等于0.9m。本实施例中，在前后方向上，辅助把手14到切割组件70的第一切割齿7111的距离L3大于等于0.3m且小于等于0.8m。示例性地，在前后方向 上，辅助把手14到切割组件70的第一切割齿7111的距离L3大于等于0.4m且小于等于0.6m。
在一些实施例中，第一开关131到第一切割齿7111的距离与第二开关144到第一切割齿7111的距离的比值大于等于1，且小于等于8.5。示例性地，第一开关131到第一切割齿7111的距离与第二开关144到第一切割齿7111的距离的比值大于等于2，且小于等于6。第一开关131到第一切割齿7111的距离与第二开关144到第一切割齿7111的距离的比值大于等于3，且小于等于5。
示例性地，第一开关131安装至主把手13且与主把手13构成转动连接。用户握持主把手13的手能够操作第一开关131转动，使其在释放状态和触发状态之间切换。本实施例中，第一开关131设置为扳机。第二开关144安装至辅助把手14且与辅助把手14构成滑动连接。用户握持辅助把手14的手能够操作第二开关144滑动，使其在释放状态和触发状态之间切换。参见图13所示，辅助把手14形成有第三容纳空间146，设置为容纳部分的第二开关144。第二开关144设置在辅助把手14的内侧且大致沿辅助把手14的延伸方向设置。这样，用户在操作修枝机100时，在各种切割角度均能够轻松地触发第二开关144。第二开关144还连接有用于输出信号的信号线或提供电能的电源线。本实施例中，上述的电源线和信号线采用塑料件进行包裹且位于连接杆60的外部，沿第一轴线102的方向延伸至后壳体10内的电路板组件81上。在一些实施例中，第二开关144还可以设置为无线开关，即第二开关144与控制装置之间不设置信号线，而是通过无线通信的方式进行信号传输。
在一些实施例中，第二开关144也可以设置在连接杆60上。示例性地，当修枝机100不设置辅助把手14的情况下，或者供用户握持的握持部位设置在连接杆60上时，第二开关144也相应地设置在连接杆60上。
在一些实施例中，参见图1所示，操作组件还包括调速单元、显示单元以及蓝牙模块等控制界面。上述的控制界面可以设置在后壳体10上且位于主把手13的前侧。当然，上述的控制界面也可以设置在其他的位置。示例性地，调速 单元至少包括调速开关，用户通过调速开关控制马达30的转速。显示单元可以设置为显示供电装置40的当前电量。蓝牙模块可以设置为与其他外部设备之间进行通信或内部设备之间进行通信。
下面针对修枝机品类之一的长杆式修枝机提出另一改进方案，以改善长杆式修枝机内组件间的脱离和/或磨损问题，进而提高长杆式修枝机的使用寿命。
如图14所示的长杆式修枝机200作为一种园林工具，其可以驱动刀片组件10运动，长杆式修枝机200可以供用户修剪灌木、绿篱、树枝等植被。
如图14至图15所示，一种长杆式修枝机200：主机200a和能量源300，主机200a包括，机壳组件60、动力组件、开关组件40、传输装置30、刀片组件10和切换组件70。在本实施例中，能量源300为电池包，电池包可拆卸连接至主机200a。作为其他实施方式，电池包可以是与主机200a分离设置，即电池包与主机200a之间通过连接线实现供电。
为了清楚的说明本申请的技术方案，定义了如图14所示的前、后。其中需要说明的是，在无特别说明的情况下，下文中所述的长杆式修枝机200是如图14所示的前后全伸展状态。
机壳组件60为构成长杆式修枝机200外形的主要构成部分，主机200a壳体形成有容纳空间，开关组件40、动力组件、传动装置和刀片组件10至少部分设置在容纳空间内。机壳组件60形成或者连接有可供用户握持的把手部和握持部50。用户可以通过一手握持把手部，另一只手握持部50来操作长杆式修枝机200。
动力组件设置为给长杆式修枝机200提供动力，动力组件包括电机20，电机20包括输出动力的电机轴21。作为其他实施方式，动力组件可以采用引擎或其他能够输出动力的零件。
开关组件40设置为控制电机20的启动或关闭，开关组件40包括用于供用户驱动的扳机41，扳机41能够绕一中心轴线103转动，从而启动电机，开关组件40邻近握持部50设置，这样用户握持在握持部50上时，可以很方便的启 动扳机41。
机壳组件60还形成有长杆组件61，长杆组件61沿第一方向延伸，长杆组件61设置在动力组件和刀片组件10之间。长杆组件61在第一方向上具有一定的长度，这样用户站在地面上时，用户就可以操作长杆式修枝机200对高处的树枝进行修剪。长杆组件61可以采用碳纤维材料制成，这样能较好的减轻长杆式修枝机200的重量，从而更加方便用户的操控。
切换组件70设置为切换刀片组件10的切割方向，可以理解的，即刀片组件10能够相对长杆组件61可保持的转动，用户可以根据实际情况切换刀片组件10的切割方向，以便用户更好的切割。如图14所示为长杆式修枝机全伸展状态，此时刀片组件10的延伸方向与长杆组件61的延伸方向基本平行。
传输装置30设置在动力组件和刀片组件10之间，设置为将电机20输出的动力传递至刀片组件10。
如图14至图21所示，刀片组件10包括第一刀片11和第二刀片12，电机20驱动第二刀片12与第一刀片11之间产生相对运动，即第二刀片12能够沿第一直线101方向相对于第一刀片11往复运动，从而实现修枝机的切割功能。第一刀片11包括主体部111和切割部112，主体部111基本沿第一直线101方向延伸，切割部112自主体部111沿垂直于第一直线101方向延伸。切割部112在沿第一直线101方向上的前后两侧分别形成有前切割刃113和后切割刃114。一个切割部112的前切割刃113和位于该切割部112前侧且相邻的另一个切割部112之间形成有一个允许灌木、绿篱等待切割物至少部分进入至这两个相邻的切割部112之间的区域，该区域定义为单元切割区域115，单元切割区域115在沿第一直线101方向上具有第一长度L1。
可以理解的，前切割刃113沿垂直于第一直线101方向上具有与主体部111连接的根部和与根部相对的顶部，后切割刃114在沿垂直于第一直线101方向上具有与主体部111连接的根部和与根部相对的顶部，单元切割区域115在沿第一直线101方向上的第一长度L1，事实上也即是一个切割部112的前切割刃 113的顶部与位于该切割部112的前侧且相邻的另一个切割部112的后切割刃114的顶部之间的距离。在本实施例中，长杆式修枝机200指的是拆卸能量源300的主机200a的重量，长杆式修枝机200是供用户在地面或者是在低处对高处树枝进行修剪的一种园林工具，因此修枝机的切割效率、主机200a的重量对于用户来说是及其重要的，其中，作为一种实施方式，第一长度L1与主机200a重量的比值大于等于4.5mm/kg且小于等于7mm/kg，将第一长度L1与主机200a重量的比值设置在上述范围内，这样，使得长杆式修枝机200的主机200a的重量比较轻，同时刀片组件10的单元切割区域115的尺寸还比较大，从而使得长杆式修枝机200的重量轻且切割能力强，进而能够使得用户使用一种重量轻的长杆式修枝机200依然能够切割比较顽固、粗壮的植被。示例性的，第一长度L1与主机200a重量的比值大于等于5毫米/千克且小于等于6.5毫米/千克。
第二刀片12的结构与第一刀片11的结构基本相同，第二刀片12包括与主体部111和切割部112结构相同的第二主体部111和第二切割齿，在此不再赘述。
继续参考图14至图21，刀片组件10在沿第一直线101方向上具有第二长度L2，其中第二长度L2与主机200a的重量的比值大于等于110毫米/千克且小于等于145毫米/千克。其中刀片组件10的长度指的是，第一刀片11在沿第一直线101方向上的长度，第一刀片11在沿直线方向上的长度越长，在单元切割区域115的距离一致的情况下，第一刀片11上能够设置的单元切割区域115越多，也就是说，在同等条件下，刀片长度越长，长杆式修枝机200能够修剪的单元切割区域115越多，同时需要注意的是，刀片长度越长这刀片组件10的重量越重，那么主机200a的重量也就更重，对于用户而言，长时间进行修剪时，用户更容易疲劳，从而影响工作效率。因此将第二长度L2与主机200a的重量的比值设置在上述范围内，既能够保证长杆式修枝机200的效率，同时又兼顾主机200a的重量，使长杆式修枝机200的人机工程较好。示例性的，第二长度L2与主机200a的重量的比值大于等于120毫米/千克且小于等于130毫米/千克， 将第二长度L2与主机200a的重量的比值设置在上述范围内，效果更好。
请一并参考图22至图26，动力组件、长杆组件61、传动装置和刀片组件10依次设置形成长杆式修枝机200的主体，长杆式修枝机200具有一重心G，其中长杆式修枝机200的重心至扳机41中心轴线103的距离大于等于55cm且小于等于70cm。其中，长杆式修枝机200的重心指的是长杆式修枝机200处于未安装能量源300时的状态，在本实施例中，主机200a的重心G不会因安装不同容量的电池包而受到影响，而长杆式修枝机200的重心会因安装不同容量的电池包而向靠近电池包的方向移动，进而更好的便于用户控制长杆式修枝机200。长杆式修枝机200在进行工作时，用户需要一手握持在把手部上，一手握持在握持部50上，并将长杆式修枝机200抬起，通过握持在把手部和握持部50上的双手控制长杆式修枝机200的切割方向，从而实现对长杆式修枝机200的控制，重心的高低影响重力势能，重力势能的大小直接影响用户在使用时对长杆式修枝机200施加的力的大小，因此在设置重心时，将重心尽可能的靠近长杆式修枝机200的后端，这样用户可以对长杆式修枝机200施加的力较小，方便用户操作长杆式修枝机200。
请参考图25至图26，传输装置30包括第一壳体31、第二壳体32、传动组件33和紧固组件34。第一壳体31和第二壳体32连接形成一容纳腔。传动组件33设置在容纳腔内，传动组件33用于电机轴21和刀片组件10之间实现动力的传递。紧固组件34设置为紧固第一壳体31和第二壳体32，也就是说紧固组件34设置为将第一壳体31连接至第二壳体32上。紧固组件34包括连接杆341、第一紧固件342、第二紧固件343和垫圈36，连接杆341，贯穿连接第二壳体32、第一壳体31和至少部分传动组件33。第一紧固件342连接至连接杆341上，以限制第一壳体31发生位移。第二紧固件343连接至连接杆341上，以限制第一紧固件342发生位移。垫圈36设置在第一壳体31和第一紧固件342之间。
传动组件33包括第一传动组331和第二传动组332，第一传动组331和第 二传动组332之间能够相互配合。电机20的电机轴21驱动第一传动组331运动，从而使第二传动组332一并运动，第二传动组332驱动刀片组件10运动。第一传动组331包括第一传动件333和第二传动件334，第一传动件333能够被电机轴21驱动从而转动，第二传动件334与第一传动件333啮合。第二传动组332包括第三传动件335和第四传动件336，当第二传动件334运动时，第三传动件335能够与之一并运动，第四传动件336与第三传动件335啮合，第四传动件336与刀片组件10连接。作为一种实施方式，传输装置30还包括驱动杆，驱动杆至少部分设置在长杆组件61内，驱动杆连接电机轴21和第一传动件333，例如，驱动杆一端与第一传动件333固定连接或者一体成型，驱动杆的另一端与电机轴21配合。在本实施例中，驱动杆与第一传动件333之间为花键连接。驱动杆的另一端与电机轴21为齿轮连接，即驱动杆上连接有大齿轮，电机轴21上连接有小齿轮，大齿轮和小齿轮之间啮合连接。通过这样设置可以将电机轴21输出的动力传递至第一传动件333。第一传动件333与第二传动件334啮合连接，即第一传动件333转动，第二传动件334随之转动，第二传动件334转动的过程中，第三转动件随之转动。第三传动件335与第四传动件336啮合连接，即第四传动件336能够被第三传动件335驱动。第三传动件335与第二传动件334一体成型，第三传动件335与第二传动件334上还形成有贯穿第三传动件335与第二传动件334的通孔，连接杆341可以穿过上述通孔。也就是说连接杆341穿过第二壳体32、通孔、第一壳体31后与第一紧固件342连接，连接杆341大致呈T型，连接杆341穿过第二壳体32后，连接杆341的T型端与第二壳体32抵接。
在本实施例中，第一传动件333、第二传动件334、第三传动件335和第四传动件336均为锥齿轮。也就说长杆式修枝机200采用两级传动，切割传动组件33的结构设置简单，易于实现。其中第一传动组331的传动比大于等于3且小于等于4。第二传动组332的传动比大于等于2且小于等于3。在此范围内，第一传动组331和第二传动组332能实现较好的传动功能，同时还能延长主机 200a的使用寿命。在一种实施例中，第一传动组331的传动比为3.44。第二传动组332的传动比为2.7。
作为一种实施方式，连接杆341上形成有外螺纹，第一紧固件342上形成有与连接杆341上的外螺纹相配合的第一内螺纹，第二紧固件343上形成有与连接杆341上的外螺纹相配合的第二内螺纹346，也就是说，第一紧固件342与第二紧固件343均与连接杆341螺纹连接。其中，第二内螺纹346至外螺纹在沿连接杆341的周向上的距离不一致。长杆式修枝机200在工作时会产生比较大的振动，因此需要将第一壳体31、第二壳体32、传动组件33之间稳定连接，从而保证长杆式修枝机200工作时的稳定性，避免因其产生振动而造成紧固件脱落，从而避免出现工具在运动时突然解体的情况。长杆式修枝机200在长时间运行后，势必会出现工具内部零部件出现损坏，这样维修工人可能需要拆除安装紧固组件34，从而移除第一壳体31，但是目前市面上的修枝机，维修工人在拆除第二紧固件343时，会出现需要破坏第二紧固件343，导致第二紧固件343无法再使用，这样维修工人需要重新更换一个新的第二紧固件343；或者即便不需要破坏第二紧固件343，在将第二紧固件343拆卸的过程中也会导致连接杆341被破坏，从而缩短了长杆式修枝机200的使用寿命，将第二内螺纹346至外螺纹在沿连接杆341的周向上的距离不一致，这样维修工人在拆除第二紧固件343时既不会损坏第二紧固件343，也不会损坏连接杆341上的外螺纹。在本实施例中，第二紧固件343在沿第二方向的截面上，第二内螺纹346基本呈椭圆形。第二方向基本垂直于连接杆341的延伸方向。
如图16、图26至图27所示，传输装置30还包括衬套35，衬套35设置在连接杆341和第一壳体31之间，第二传动件334和第三传动件335套在连接杆341上，当长杆式修枝机200在运行时，第二传动件334和第三传动件335高速运转时，势必会让连接杆341产生振动，连接杆341与第一壳体31之间会产生摩擦，长时间后会影响第一壳体31的寿命，进而影响长杆式修枝机200的寿命。在第一壳体31和连接杆341之间设置衬套35，能够有效的延长第一壳体 31的寿命，进而延长整机的使用寿命。示例性的，在沿连接杆341的延伸方向上，第一壳体31在朝向传动组件33的方向上凹陷形成一凹槽311，衬套35设置在凹槽311内，示例性的，垫圈36设置在衬套35和紧固组件34之间。垫圈36设置为减少衬套35对第一紧固件342磨损，保证紧固组件34与第一壳体31和第二壳体32之间连接的稳定性，从而延长传输装置30的使用寿命，延长长杆式修枝机200的使用寿命。在本实施例中，衬套35可以采用耐磨的金属材质制成。
