请参阅图1及图2所示，在本申请一实施例中，推拉组件32可活动安装于主手柄21上，推拉组件32可以设置在主手柄21的顶部，也可以设置在主手柄21的侧面上。推拉组件32 可以用于限定扳机开关312的活动，以避免驱动的扳机开关312使手持式电动工具被误触。当推拉组件32作用在扳机开关312上时，扳机开关312是不允许相对于主手柄21进行枢转，反之，当推拉组件32未作用在扳机开关312上时，扳机开关312是允许相对于主手柄21进行枢转。
请参阅图2、图3及图4所示，在本申请一实施例中，推拉组件32可包括推动杆321、限位柄322、弹簧安装座323以及弹簧324。其中，主手柄21上可设置有推动杆安装槽202，推动杆321可活动设置于推动杆安装槽202内。推动杆321可与限位柄322相连接，且两者之间形成有夹角，该夹角的大小可以在60°～120°的范围之间，可以为60°，也可以为90°，还可以为120°，限位柄322可以位于推动杆321靠近限位开关313的一端上。弹簧安装座323可以设置在主手柄21的内部，且弹簧324可以设置在弹簧安装座323内，且弹簧324可以与推动杆321相连。因此，当推动推动杆321时，弹簧324会被压缩，而当松开推动杆321时，弹簧324会复位，带动推动杆321返回初始位置。为了便于操作者推动推动杆321，因此可以在推动杆321的表面设有多个条纹203，以增加推动杆321与操作者手部之间的摩擦力。
请参阅图2及图3所示，在本申请一实施例中，当推动杆321活动时，会带动限位柄322同步活动。为了便于通过限位柄322对扳机开关312进行限位，扳机开关312可以设为中空结构，其内部设有一个空腔。当未推动推动杆321或推动杆321未推压到预定位置时，限位柄322与扳机开关312的尾部接触，此时扳机开关312被限位柄322卡住，无法转动，限位柄322可以对扳机开关312起到限位作用。当操作者推动推动杆321且推到预定位置时，限位柄322可移动到扳机开关312的空腔内，此时扳机开关312被解锁，操作者可以按下扳机开关312，以驱动手持式电动工具启动。手持式电动工具在使用过程中，推拉组件32一直处于解锁状态，当手掌没有离开主手柄21的抓握区，即推拉组件32一直处于解锁状态状态下时，即使限位开关313停止，只要在预定时间内，重新按压扳机开关312，则手持式电动工具可以重新启动，预定时间可以为一分钟。手持式电动工具的启动顺序为，按下上电开关311给手持式电动工具上电，推动推动杆321，使得限位柄322移动到扳机开关312的空腔中，再按下扳机开关312，扳机开关312触发限位开关313导通，此时上电开关311与限位开关313均被触发，从而手持式电动工具开始工作。当操作者松开推动杆321时，推动杆321在弹簧324的作用下返回原始状态，此时限位柄322返回到初始位置，扳机开关312返回到初始位置，从而扳机开关312与限位开关313不接触，从而手持式电动工具在经过预定时间后断电并停止工作。当然，在其他实施例中，也可不设置上电开关311，可以仅靠限位开关313 控制手持式电动工具的工作。为了防止推动杆321被误触，导致手持式电动工具被启动，因此推拉组件32可以被设置成完成至少两种动作后，扳机开关312被解锁。第一动作可以为推动杆321沿主手柄21前后滑动，表征为第一方向移动，第二动作可以为推动杆321沿主手柄21前后倾斜滑动，表征为第二方向移动。第一方向可以与主手柄21的方向基本平行，第二方向可以与主手柄21的方向之间形成一定的夹角。
请参阅图3及图4所示，在本申请一实施例中，为了防止推动杆321在活动过程中发生偏移，因此在推动杆321的两侧可设有相互对称的两个主滑动支撑块3211，在推动杆321的两侧也可设有相互对称的两个副滑动支撑块3212。两个主滑动支撑块3211可分别滑动设置在两个主滑动限位槽204内，两个副滑动支撑块3212可分别滑动设置在两个副滑动限位槽205内，主滑动限位槽204与副滑动限位槽205可以设置在主手柄21的对应位置上。通过主滑动支撑块3211与主滑动限位槽204的配合，副滑动支撑块3212与副滑动限位槽205的配合，能够在推动杆321在活动过程中起到导向的作用，防止推动杆321在活动过程中发生偏移。当然，主滑动支撑块3211与副滑动支撑块3212的结构可以相似，主滑动限位槽204与副滑动限位槽205的结构也可以相似。
请参阅图2、图4、图5及图6所示，在本申请一实施例中，当主滑动限位槽204与副滑动限位槽205的结构相似时，以主滑动限位槽204为例进行说明，主滑动限位槽204可以包括第一槽体2041与第二槽体2042，第一槽体2041与第二槽体2042之间可形成一定的夹角，该夹角可以大于90°，以保证主滑动支撑块3211在主滑动限位槽204内顺利滑动。在本实施例中，第一槽体2041的方向与推动杆321的方向大致平行，第二槽体2042可以位于第一槽体2041的一端，第一槽体2041靠近限位开关313。第二槽体2042沿着主手柄21顶部朝向主手柄21底部的方向布置。推拉组件32可以贯穿抓握区布局于主手柄21的握持区背脊，操作者在启动推拉组件32时，只需要手掌给予推拉组件32一个前推力和握紧下压即可解锁扳机开关312。具体为，在手掌的推动作用下，向前推动推动杆321，使得推动杆321先沿第一槽体2041向前平移滑动，再握紧主手柄21，使得推动杆321沿着第二槽体2042向下方移动。而在其他实施例中，第一槽体2041的方向与推动杆321的方向大致平行，第二槽体2042可以位于第一槽体2041的另一端。第二槽体2042沿着主手柄21顶部朝向主手柄21底部的方向布置。操作者在启动推拉组件32时，只需要手掌给予推拉组件32一个前推力和握紧下压即可解锁扳机开关312。具体为，在手掌的作用下，握紧推动杆321，使得推动杆321先沿第二槽体2042先向下方移动，再向前推动推动杆321，使得推动杆321再沿着第一槽体2041向前平移滑动。这个过程仅依靠手掌就可以完成操作，即推动杆321先完成第一动作，然后 完成第二动作即可实现扳机开关312的解锁。此时扳机开关312可以被触发，激活限位开关313，扳机开关312可将启动信号传递到手持式电动工具的控制电路，将手持式电动工具启动。当推拉组件32完成对扳机开关312的解锁动作后，推动杆321位于主手柄21内，以提高操作者的舒适感。
请参阅图9及图13所示，在本申请一实施例中，刀具组件40可以包括刀板41、链轮42、链条43以及张紧器44。驱动组件与链条43之间可以通过链轮42进行传动，链轮42可以转动安装在第二壳体102向内凹陷形成的安装槽内。刀板41的一端可以位于安装槽内，并通过张紧器44与壳体组件10相连。张紧器44可以安装在第二壳体102上，可以通过张紧器44调节链条43的松紧程度。链轮42可以包括链轮盘和链轮齿，链轮齿可以固定连接在链轮盘的一侧。链条43可以沿着刀板41的周向进行布置，并且与链轮齿啮合传动。具体的，刀板41沿其周向设置有定位凹槽，链条43上的传动齿位于定位凹槽内，当驱动组件驱动链轮42转动时，链条43沿着定位凹槽移动，以完成切割。驱动组件可以为驱动电机47，在本实施例中，为了能够实现链轮42的制动，因此可以在壳体组件10的前端上设有制动手柄451，制动手柄451可控制制动钢带452工作，链轮盘的外表面圆周上设置有多条凹槽，制动钢带452可围绕设置在凹槽上，当扳动制动手柄451时，制动钢带452收紧以驱使链轮42停止转动。

请参阅图8及图9所示，在本申请一实施例中，由于手持式电动工具在工作过程中，驱动电机47会不可避免的产生一定的热量，导致壳体组件10的内部温度较高，为了能够及时对壳体组件10的内部进行散热，因此壳体组件10内还可设有散热组件50，散热组件50可以包括散热器、导风圈54以及控制器53。其中，导风圈54可以设置在驱动电机47的外圈上，导风圈54可以与壳体组件10之间形成一个风道。为了能够使风道内的热空气顺利排出，因此在壳体组件10上可分别设有进风口51与出风口52。进风口51可以位于壳体组件10后部的侧面上，具体的，进风口51可以位于壳体组件10后部的左侧，且进风口51向后且向下倾斜。出风口52可以位于壳体组件10的底部，具体的，出风口52可以位于壳体组件10内 驱动电机47的正下方，出风口52相对于壳体组件10纵向且向下开口，出风口52可以与风道相连通。需要说明的是，散热器可以安装在壳体组件10内，散热器正对进风口51。在本实施例中，上述提到的控制电路可以为控制器53，控制器53可以控制驱动电机47的工作，控制器53可以安装在散热器的一侧。当需要对壳体组件10的内部进行冷却时，外部冷空气可以从进风口51进入到壳体组件10的内部，经过散热器后，进入到风道内，可以对驱动电机47进行散热，最终热空气从出风口52排出。
请参阅图7所示，在本申请一实施例中，为了提高驱动电机47的续航能力，因此在手持式电动工具上还可以设置电池组件60，电池组件60可以与驱动电机47之间电连接，用于为驱动电机47提供能源。电池组件60与壳体组件10为两个单独的个体，电池组件60可以包括电源线61、电池架62以及电池包63。其中，电池包63可以安装在电池架62上，电池架62可以设置成背负式结构，操作者可以背负电池架62。在电池架62上可设有供电接口64，供电接口64可以与电池包63电连接。在手柄组件20上可设有电源接口65，电源接口65可以与驱动电机47、控制器53等电连接，且电源接口65可以位于主手柄21的尾部一侧。供电接口64与电源接口65之间可以通过电源线61电连接，电池包63可对壳体组件10内部的电器元件进行供电。
请参阅图14、图15及图16所示，在本申请一实施例中，当不使用手持式电动工具时，电源接口65与电源线61是断开的，导致电源接口65直接暴露在空气中的，空气中的潮湿气体、灰尘等杂质可能会损坏电源接口65的结构。为了能够对电源接口65进行防护，因此在手持式电动工具上还可设有防护组件70，通过防护组件70对电源接口65进行防护。具体的，在第一壳体101与第二壳体102的尾部可各设置有半圆凹槽，当第一壳体101与第二壳体102固定安装后，两个半圆凹槽可以组合并形成一个接口安装孔72，此时电源接口65可以安装在接口安装孔72内。防护组件70可以设置在接口安装孔72的一侧，以对电源接口65进行防护。
请参阅图15及图16所示，在本申请一实施例中，防护组件70可以包括防护盖71与安装带73。其中，防护盖71的一端与壳体组件10连接，防护盖71的另一端上形成有遮盖部711，遮盖部711覆盖在电源接口65上，并与电源接口65四周的壳体组件10相贴合以形成密封面。具体的，遮盖部711可以包括贴合部7111与嵌入部7112，嵌入部7112可以嵌入到电源接口65内，贴合部7111可以设于嵌入部7112的外部，贴合部7111的外径大于电源接口65的外径，贴合部7111可以将电源接口65全部覆盖在内，使得贴合部7111与电源接口65外侧的壳体组件10的侧面紧密贴合在一起。当然，为了提高密封性，因此可在接口安装 孔72外侧的壳体组件10上设有一环形凸起结构，以便贴合部7111更好的与壳体组件10贴合在一起。

请参阅图17及图18所示，在本申请一实施例中，在操作者使用手持式电动工具时，操作者可能需要在树木的不同高度位置锯切树枝，在操作者移动位置时，双手不便于握持手持式电动工具，但手持式电动工具又必须随身携带，以便随时使用，因此可在手持式电动工具上设置挂钩组件80，以使手持式电动工具能够通过挂钩组件80随时悬挂在操作者身上。挂钩组件80可包括侧挂钩81与底挂钩86，侧挂钩81与底挂钩86可安装在壳体组件10的尾部，具体的，侧挂钩81可以位于靠近壳体组件10尾部的中间位置，底挂钩86可以位于靠近壳体组件10尾部的底部位置。侧挂钩81与底挂钩86枢转的连接到壳体组件10，且侧挂钩81与底挂钩86的枢转轴在空间上大致垂直。需要说明的是，由于壳体组件10的尾部和底面之间的过渡面为弧形，因此，底挂钩86可以设为同样的弧形结构，以和壳体组件10的尾部和底面之间的过渡面相适配。侧挂钩81与底挂钩86均与壳体组件10转动安装在一起，底挂钩86可以位于侧挂钩81的下方。在壳体组件10上设置有用于安装侧挂钩81的突出位置与收纳位置，在壳体组件10上也设置有用于安装底挂钩86的突出位置与收纳位置。
请参阅图19、图20、图21及图22所示，在本申请一实施例中，当侧挂钩81处于收纳状态和/或突出状态时，此时侧挂钩81可以位于侧收纳槽82内，侧收纳槽82可以设置在壳体组件10的尾部的中间位置。操作者可通过操作侧挂钩81，使其位于不同的位置，以使侧挂钩81位于不同的工作状态。侧挂钩81可包括第一侧转轴811、第二侧转轴812、第一连接件813、第二连接件814以及侧操作件815，其中，第一侧转轴811、第一连接件813、侧操作件815、第二连接件814以及第二侧转轴812可依次连接并形成一个近似框形的结构，构成侧挂钩81。在本实施例中，可通过对一根长杆依次进行折弯，以达成侧挂钩81所需的形状，或者，也可通过一体成型的方式对侧挂钩81进行生产。
请参阅图19及图20所示，在本申请一实施例中，第一连接件813的形状为圆柱体形， 然不限于此，第一连接件813也可以为长方体形，三棱柱形等，第一连接件813的具体形状可不加限制，可根据实际需求进行设定，只要能够满足侧挂钩81整体能与侧收纳槽82相配合，以实现对侧挂钩81的突出状态的限位即可。第二连接件814的形状为圆柱体形，然不限于此，第二连接件814也可以为长方体形，三棱柱形等，第二连接件814的具体形状可不加限制，可根据实际需求进行设定，只要能够满足侧挂钩81整体能与侧收纳槽82相配合，以实现对侧挂钩81的突出状态的限位即可。侧操作件815的形状为圆柱体形，然不限于此，侧操作件815也可以为长方体形，三棱柱形等，侧操作件815的具体形状可不加限制，可根据实际需求进行设定，只要能够满足侧挂钩81整体能与侧收纳槽82相配合，以实现对侧挂钩81的收纳状态的限位即可。
请参阅图19及图20所示，在本申请一实施例中，第一侧转轴811与第一连接件813的连接处可以为弯曲形，然不限于此，第一侧转轴811与第一连接件813也可直接相连，第一侧转轴811与第一连接件813的连接处可形成一定的角度。第一连接件813与侧操作件815的连接处可以为弯曲形，然不限于此，第一连接件813与侧操作件815也可直接相连，第一连接件813与侧操作件815的连接处可形成一定的角度。侧操作件815与第二连接件814的连接处可以为弯曲形，然不限于此，侧操作件815与第二连接件814也可直接相连，侧操作件815与第二连接件814的连接处可形成一定的角度。第二连接件814与第二侧转轴812的连接处也可以为弯曲形，然不限于此，第二连接件814与第二侧转轴812也可直接相连，第二连接件814与第二侧转轴812的连接处可形成一定的角度。在本实施例中，第一侧转轴811与第一连接件813的连接处为弯曲形，第一连接件813与侧操作件815的连接处为弯曲形，侧操作件815与第二连接件814的连接处为弯曲形，第二连接件814与第二侧转轴812的连接处为弯曲形，可便于通过侧收纳槽82对侧挂钩81进行限位。
请参阅图19、图21及图22所示，在本申请一实施例中，第一侧转轴811与第二侧转轴812可分别枢转连接到开设于壳体组件10内的两个转动孔内，两个转动孔可相互连通，也可相互不连通。当侧挂钩81处于突出位置时，为了能够实现对侧挂钩81的定位，以防止侧挂钩81返回收纳位置，此时第一侧转轴811、第一连接件813的连接处与第二侧转轴812、第二连接件814的连接处之间的间距记为第一间距，第一连接件813、侧操作件815的连接处与第二连接件814、侧操作件815的连接处之间的间距记为第二间距，其中，第一间距小于第二间距，即侧挂钩81的整体可以近似为一个等腰梯形，且第一侧转轴811、第二侧转轴812位于等腰梯形的两个平行边中较短的一条边上。当第一连接件813与第二连接件814的一端的间距增加时，侧挂钩81内部会产生一定的弹力，以驱使第一连接件813与第二连接件814 返回到突出位置。
请参阅图23所示，在本申请一实施例中，为了能够对侧挂钩81进行限位，防止侧挂钩81在使用过程中从突出状态自动变为收纳状态，因此可在上述其中一个转动孔的一侧设有侧突出限位槽83，侧突出限位槽83可与第二连接件814的一端相配合，当侧挂钩81从收纳状态转换为突起状态时，此时可转动侧挂钩81，侧挂钩81开始从侧收纳槽82内脱离，此时由于第一连接件813的一端与第二连接件814的一端之间的间距大于第一间距，即第一连接件813与第二连接件814受到内部弹力的影响，第一连接件813的一端与第二连接件814会有相互接近的趋势，即第一连接件813与第二连接件814能够相对于侧操作件815发生弹性形变，当第一连接件813与第二连接件814发生弹性形变时，则第一侧转轴811与第二侧转轴812之间的间距可随之发生相应的变化。由于侧收纳槽82的形状与侧挂钩81的形状相匹配，且其中一个转动孔上设有侧突出限位槽83，当侧挂钩81开始从侧收纳槽82内脱离时，第一连接件813与第二连接件814会自主向内收缩，直至第二连接件814的一端卡入侧突出限位槽83内，此时第一连接件813的一端与第二连接件814的一端之间的间距会减少，同时，当第二连接件814的一端卡入侧突出限位槽83内时，第二连接件814的一端会与侧突出限位槽83产生碰撞，会产生声音，以提示操作者侧挂钩81已处于突起状态。在本实施例中，侧突出限位槽83是与第二连接件814的一端相配合的，在其他实施例中，侧突出限位槽83也可以安装在另一个转动孔的一侧，侧突出限位槽83可与第一连接件813的一端相配合，当然，两个转动孔的一侧均可设有侧突出限位槽83，第一连接件813、第二连接件814可分别与两个侧突出限位槽83相配合，也可实现对侧挂钩81的突起状态的限位。
请参阅图23、图24及图25所示，在本申请一实施例中，当侧挂钩81需要从突起状态转化为收纳状态时，此时可转动侧挂钩81，侧挂钩81开始从侧突出限位槽83内脱离，随着侧挂钩81的转动，第一连接件813的一端与第二连接件814的一端之间的间距会增大，侧挂钩81内部会产生一个弹力。为了能够实现对侧挂钩81的限位，因此可在远离转动孔的侧收纳槽82的一侧上设有侧收纳限位槽84，当侧挂钩81转动时，侧挂钩81开始从侧突出限位槽83内脱离，第一连接件813与第二连接件814会自主向外张开，直至侧操作件815沿着侧收纳槽82的一侧转动并卡入到侧收纳限位槽84内，此时可实现对侧挂钩81的收纳状态的限位。同时，当侧操作件815卡入侧收纳限位槽84内时，侧操作件815会与侧收纳限位槽84产生碰撞，会产生声音，以提示操作者侧挂钩81已处于收纳状态。
请参阅图24及图25所示，在本申请一实施例中，当侧挂钩81处于收纳状态时，由于侧挂钩81的侧操作件815是卡在侧收纳限位槽84内的，此时操作者不好直接将侧操作件815 从侧收纳限位槽84内分离。为了便于操作者转动侧挂钩81，因此可在壳体组件10上开设有侧操作槽85，侧操作槽85可位于侧收纳限位槽84中，同时侧操作槽85的深度与宽度可大于侧收纳限位槽84的深度与宽度，操作者通过侧操作槽85可将侧操作件815从侧收纳限位槽84内取出，以使侧挂钩81从收纳状态变化为突起状态。此时侧挂钩81所处的平面可与壳体组件10的侧面所处的平面形成一定的角度，该角度可以为90°，也可以为85°、80°等。当然，侧挂钩81的旋转方向也可不加限制。

请参阅图26所示，在本申请一实施例中，具体的，第一前腿8631的形状为圆柱体形，也可以为长方体形，三棱柱形等。第二前腿8641的形状为圆柱体形，也可以为长方体形，三棱柱形等。第一后腿8632的形状为圆柱体形，也可以为长方体形，三棱柱形等。第二后腿8642的形状为圆柱体形，也可以为长方体形，三棱柱形等。
请参阅图26及图28所示，在本申请一实施例中，具体的，第一底转轴861与第一前腿8631的连接处可以为弯曲形，第一底转轴861与第一前腿8631的连接处可形成一定的角度。第一前腿8631与第一后腿8632的连接处可以为弯曲形，第一前腿8631与第一后腿8632的连接处可形成一定的角度，其中，第一前腿8631与第一后腿8632之间的夹角大于90°，且小于170°，第一前腿8631与第一后腿8632连接处的弯曲角度、壳体组件10的侧面与底面连接处的弯曲角度可以相同。第一后腿8632与底操作件865的连接处可以为弯曲形，第一后腿8632与底操作件865的连接处可形成一定的角度。底操作件865与第二后腿8642的连接处可以为弯曲形，底操作件865与第二后腿8642的连接处可形成一定的角度。第二后腿8642与第二前腿8641的连接处可以为弯曲形，第二后腿8642与第二前腿8641的连接处可形成一 定的角度，其中，第二后腿8642与第二前腿8641之间的夹角大于90°，且小于170°，第二后腿8642与第二前腿8641连接处的弯曲角度、壳体组件10的侧面与底面连接处的弯曲角度可以相同。第二前腿8641与第二底转轴862的连接处可以为弯曲形，第二前腿8641与第二底转轴862的连接处可形成一定的角度。
请参阅图27所示，在本申请一实施例中，壳体组件10上可设有底收纳槽871、底突出限位槽872、限位块874以及底收纳限位槽873。其中，底收纳槽871可设于壳体组件10的侧面与底面的连接处，底挂钩86可转动设于底收纳槽871内，底收纳槽871上可设有底突出限位槽872、限位块874以及底收纳限位槽873，底突出限位槽872位于底收纳槽871与限位块874的一端的相接处，底收纳限位槽873位于底收纳槽871与限位块874的另一端的相接处。底突出限位槽872与底收纳限位槽873可分别与底挂钩86相配合，使得底挂钩86可具备不同的限位状态，例如当底挂钩86与底突出限位槽872相配合时，底挂钩86处于突出状态，当底挂钩86与底收纳限位槽873相配合时，底挂钩86处于收纳状态。
请参阅图26及图27所示，在本申请一实施例中，第一底转轴861与第二底转轴862可分别枢转连接到开设于底收纳槽871内的两个转动孔内，且第一底转轴861的一端与第二底转轴862的一端相互远离。当底挂钩86处于底突出限位槽872的位置时，即底挂钩86处于突出状态时，为了能够实现对底挂钩86的定位，此时第一底转轴861与第二底转轴862之间的间距记为第三间距，当底挂钩86处于底收纳限位槽873的位置时，即底挂钩86处于收纳状态时，此时第一底转轴861与第二底转轴862之间的间距记为第四间距，其中，第三间距大于第四间距。
请参阅图26、图27及图28所示，在本申请一实施例中，底收纳槽871的一个转动孔的一侧可设有底突出限位槽872，底突出限位槽872可与第一前腿8631的一端相配合。当转动底挂钩86时，底挂钩86从底收纳限位槽873内脱离。此时第一前腿8631、第二前腿8641、第一后腿8632以及第二后腿8642会受到内部弹力的影响，能够相对于底操作件865发生弹性形变。当底挂钩86经过限位块874后，第一前腿8631会自主向外展开，直至第一前腿8631的一端卡入到底突出限位槽872内时，第一前腿8631的一端会与底突出限位槽872的内壁产生碰撞，会产生声音，以提示操作者底挂钩86处于突出状态。在另一实施例中，底突出限位槽872也可设置在另一转动孔的一侧，底突出限位槽872可与第二前腿8641的一端配合。在另一实施例中，底收纳槽871的两个转动孔的一侧均可设有底突出限位槽872，两个底突出限位槽872也可分别与第一前腿8631与第二前腿8641相配合。限位块874、底收纳限位槽873的安装位置与数量均可随着底突出限位槽872的设置的位置与数量而变化。当底突出限 位槽872的数量为一个时，底突出限位槽872、限位块874以及底收纳限位槽873的安装位置需要位于其中一个转动孔的一侧。
请参阅图26、图27及图28所示，在本申请一实施例中，当将底挂钩86收起时，操作者可向内挤压第一前腿8631与第二前腿8641，第一前腿8631和/或第二前腿8641可从底突出限位槽872内分离。通过转动底挂钩86，当第一前腿8631经过限位块874后，第一前腿8631会卡入到底收纳限位槽873内，底挂钩86被收起，底挂钩86贴合在底收纳槽871内，不会影响操作者的正常操作。需要将底挂钩86从收纳状态转化为突出状态时，为了便于操作者转动底挂钩86，底操作件865可设置成弧形杆，底操作件865的凸出的部分可与底收纳槽871分离。底挂钩86内的第一前腿8631与第二前腿8641所处的平面可与壳体组件10的侧面所处的平面形成一定的角度，该角度可以为90°，也可以为85°、80°等。底挂钩86的旋转方向也可不加限制，底挂钩86的旋转方向所处平面可与手持式电动工具的链条43的旋转方向所处平面相互垂直、相互平行或者形成一定的夹角，该夹角可以为85°、80°、20°等。
请参阅图29、图30及图31所示，在本申请一实施例中，当操作者将手持式电动工具悬挂到身上时，可通过侧挂钩81和/或底挂钩86与操作者身上的工具扣88配合。以底挂钩86为例进行说明，可将底挂钩86与工具扣88相连，实现手持式电动工具的悬挂。工具扣88可包括钩体881和转动件882，钩体881可固定在操作者的身上，转动件882可转动设置在钩体881上，可通过底操作件865与转动件882的配合，实现手持式电动工具的悬挂或分离。
请参阅图29、图30及图31所示，在本申请一实施例中，操作者将手持式电动工具悬挂在工具扣88上时，可单手提起电动工具，并向工具扣88的方向移动。底挂钩86的底操作件865与工具扣88的转动件882接触，由于底挂钩86被底突出限位槽872限位，底挂钩86无法转动。底操作件865会推动转动件882转动，以使底挂钩86能够位于工具扣88内，实现单手对手持式电动工具的悬挂。
请参阅图32、图33及图34所示，在本申请一实施例中，操作者将手持式电动工具从工具扣88分离时，可单手提起手持式电动工具，并控制底操作件865向转动件882的方向移动。当底操作件865位于转动件882的下方一侧时，操作者可转动手持式电动工具，第一后腿8632或第二后腿8642会与转动件882接触。第一后腿8632或第二后腿8642会推动转动件882向内转动，操作者可单手向上提起手持式电动工具底挂钩86从工具扣88内分离。
请参阅图35及图36所示，在本申请一实施例中，为了能够对手持式电动工具的电源线61进行整理，防止操作者在使用手持式电动工具时，过长的电源线61对操作者的正常操作 产生影响，因此还可在手持式电动工具上设置挂圈组件90，挂圈组件90可对电源线61进行整理。挂圈组件90可包括悬挂主体91、第一固定主体92、第二固定主体93以及第一开口94。悬挂主体91上可设有第一开口94，可通过第一开口94对悬挂主体91进行定位。悬挂主体91可以为圆环形、椭圆环形或者方形等，悬挂主体91的具体形状可根据实际需求进行设定。第一开口94可以为圆形、椭圆形或者矩形等，第一开口94的具体形状可根据实际需求进行设定，只要能够满足通过第一开口94对悬挂主体91进行定位即可。
请参阅图35所示，在本申请一实施例中，具体的，第一固定主体92和第二固定主体93可固定在悬挂主体91的一端，且第一固定主体92与第二固定主体93位于悬挂主体91的同一侧。第一固定主体92与悬挂主体91之间、第二固定主体93与悬挂主体91之间可以是一体成型的，也可通过卡扣、螺栓或粘接的方式进行连接。
请参阅图35、图37及图38所示，在本申请一实施例中，第一固定主体92与第二固定主体93之间为分体结构。第一固定主体92和第二固定主体93可以为半圆弧形或者半椭圆形。第一固定主体92的开口一侧可与第二固定主体93的开口一侧相配合形成第二开口95。第一固定主体92与第二固定主体93的结构可不相同，例如，第一固定主体92可为半椭圆形，第二固定主体93可为半圆弧形，第一固定主体92与第二固定主体93的具体结构可不加限制，只要能够满足第一固定主体92的开口一侧与第二固定主体93的开口一侧可相配合形成第二开口95即可。第二开口95可以为圆形、椭圆形或者矩形等，第二开口95的具体形状可根据实际需求进行设定，只要能够满足通过第二开口95对电源线61进行夹持即可。第一固定主体92与第二固定主体93之间可设置第一间隙98，当第一固定主体92与第二固定主体93发生弹性形变时，第一间隙98的大小是随之变化的，电源线61可从第一间隙98内穿到第一固定主体92与第二固定主体93之间，通过第二开口95对电源线61进行整理。
请参阅图35、图37及图38所示，在本申请一实施例中，当需要将电源线61放置在第二开口95内时，电源线61可通过第一固定主体92与第二固定主体93之间的第一间隙98卡入第二开口95内。当然，由于操作者使用手持式电动工具时，会不可避免的带动电源线61运动，为了避免电源线61从第一固定主体92与第二固定主体93之间的第一间隙98内脱落，可在第一固定主体92和第二固定主体93的一端都设置限位挂钩96，通过两个限位挂钩96对电源线61进一步限位，能够防止电源线61从第一固定主体92与第二固定主体93之间的第一间隙98内脱落。
请参阅图37、图38及图42所示，在本申请一实施例中，第一开口94与第二开口95之间是不连通的，此时第一开口94可悬挂在安全绳97上，电源线61仅能通过第一固定主体 92与第二固定主体93之间的第一间隙98放入至第二开口95内，以实现对电源线61的整理。然不限于此，第一开口94与第二开口95之间也可以是连通的，此时第一开口94可悬挂在安全绳97上，电源线61不仅能够通过第一固定主体92与第二固定主体93之间的第一间隙98放入至第二开口95内，也能通过第一开口94放入到第二开口95内，能够在一定程度上提升泛用性。
请参阅图36及图39所示，在本申请一实施例中，第一固定主体92与第二固定主体93之间为整体结构。第一固定主体92的一端固定在悬挂主体91上，第二固定主体93的一端也固定在悬挂主体91上，第一固定主体92的另一端与第二固定主体93的另一端相互连接，第一固定主体92与第二固定主体93之间形成第二开口95。电源线61可从第二开口95内穿过，以对电源线61进行整理。第一固定主体92与第二固定主体93之间可以是一体成型的，也可通过卡扣、螺栓或粘接的方式进行连接。
请参阅图39所示，在本申请一实施例中，第一固定主体92和第二固定主体93均可包括相互连接的圆弧形结构与L形结构。第一固定主体92的圆弧形结构的一端可安装在悬挂主体91上，第二固定主体93的圆弧形结构的一端也可安装在悬挂主体91上，第一固定主体92的L形结构的一端可与第二固定主体93的L形结构的一端相连，第一固定主体92的圆弧形结构的开口一侧可与第二固定主体93的圆弧形结构的开口一侧相互配合以形成第二开口95。在本申请另一实施例中，第一固定主体92和第二固定主体93的L形结构的一端可安装在悬挂主体91上，第一固定主体92的圆弧形结构的一端可与第二固定主体93的圆弧形结构的一端相连，第一固定主体92的圆弧形结构的开口一侧可与第二固定主体93的圆弧形结构的开口一侧相互配合以形成第二开口95。
请参阅图39所示，在本申请一实施例中，第一固定主体92和第二固定主体93可仅包括圆弧形结构，第一固定主体92和第二固定主体93的一端可安装在悬挂主体91上，且第一固定主体92的另一端与第二固定主体93的另一端相连，第一固定主体92的圆弧形结构的开口一侧可与第二固定主体93的圆弧形结构的开口一侧相互配合以形成第二开口95。在本申请另一实施例中，第一固定主体92和第二固定主体93可仅包括L形结构第一固定主体92和第二固定主体93的一端可安装在悬挂主体91上，且第一固定主体92的另一端与第二固定主体93的另一端相连，第一固定主体92的L形结构的一侧可与第二固定主体93的L形结构的一侧相互配合以形成第二开口95。
请参阅图39所示，在本申请一实施例中，第一开口94与第二开口95之间可连通，第一固定主体92固定在悬挂主体91的一端与第二固定主体93固定在悬挂主体91的一端之间可 形成第二间隙99，第二间隙99的宽度可不大于电源线61的直径，第二开口95的内径也可不大于电源线61的直径，且第二间隙99的宽度小于第二开口95的内径，将电源线61夹持在第二开口95内。电源线61的接头可穿过第一开口94，并可将电源线61放入第二开口95内，实现对电源线61的整理。第二开口95可对电源线61进行夹紧，且通过第二间隙99对电源线61进行限位，可进一步将电源线61夹紧。
请参阅图40及图41所示，在本申请一实施例中，当操作者不使用手持式电动工具时，需要对手持式电动工具的电源线61进行收纳，此时可将电源线61围绕在悬挂主体91的第一开口94上，以完成收纳，或者可将电源线61多次折叠后放入至第一开口94内，通过第一开口94对多次折叠的电源线61进行限位。
请参阅图42所示，在本申请一实施例中，当需要对过长的电源线61等进行整理时，安全绳97可悬挂在墙壁上，或者固定在其他地方，安全绳97可套设有多个挂圈组件90，悬挂主体91挂设在安全绳97上，电源线61可依次穿过多个挂圈的第二开口95，实现对电源线61的整理。
综上所述，通过本申请提供的一种手持式电动工具，推动杆贯穿主手柄，且启动推拉组件只需要手掌给推动杆一个前推力和握紧下压即可解锁开关扳机，推动杆运行轨迹是先沿主手柄向前平移滑动，再沿着主手柄斜面或引导筋向下方移动，这个过程均在手掌的推力下就可以完成操作，能够改善通过拇指解锁扳机开关，导致使用时舒适度不佳的问题。同时设置挂钩组件和挂圈组件，操作者可以通过挂钩组件将电动工具悬挂在身上，通过挂圈组件对电源线进行收纳整理，能够提升电动工具使用的便捷性。
