具体实施方式
下面对本申请实施方式中的技术方案进行清楚、完整地描述，显然，所描述的实施方式仅仅是本申请一部分实施方式，而不是全部的实施方式。基于本申请中的实施方式，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施方式，都属于本申请保护的范围。
需要说明的是，当组件被称为“连接于”另一个组件，它可以直接连接于另一个组件上或者也可以存在居中的组件。当一个组件被认为是“设置于”另一个组件，它可以是直接设置在另一个组件上或者可能 同时存在居中组件。当一个组件被认为是“固定于”另一个组件，它可以是直接固定在另一个组件上或者可能同时存在居中组件。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本申请。本文所使用的术语“或/及”包括一个或多个相关的所列项目的任意的和所有的组合。
传统技术中的钳状工具的夹持范围较为固定，难以根据使用人员不同的需求更改夹持开口最大行程所限定的范围，只能夹持大小处于某一夹持范围内的物品，当需要夹持的物品大小超过该夹持范围的最大值时，使用人员就需要更换另一把钳状工具进行处理，使用较为不便。
基于此，本申请提供一种钳状工具100，钳状工具100用于夹持、弯折或者切断金属类制品。本实施方式中，钳状工具100用于夹持、弯折或者切断丝金属丝和金属薄片类产品。可以理解，在其他实施方式中，该钳状工具100也可用于夹持、弯折或者切断其他类型的物品。
请参阅图1至图10，图1为本申请提供的钳状工具100的第一个实施例的结构示意图；图2为本申请提供的钳状工具100的第一个实施例另一视角下的结构示意图；图3为图1中钳状工具100的分解结构示意图；图4为本申请中钳状工具100第一个实施例中销轴31的结构示意图；图5为图4中销轴31在另一视角下的结构示意图；图6为图1中钳状工具100的部分结构示意图；图7为图1中钳状工具100的正面结构示意图；图8为图7中钳状工具100在A-A截面处的剖面结构示意图；图9为图7中钳状工具100在B-B截面处的剖面结构示意图；图10为图7中钳状工具100在另一状态下B-B截面处的剖面结构示意图。
在本申请提供的钳状工具100的第一个实施例中，该钳状工具100包括第一钳体10、转动配合组件30及第二钳体20，转动配合组件30可活动地连接于第一钳体10，转动配合组件30包括第一配合部311；第二钳体20通过转动配合组件30与第一钳体10可转动连接；第二钳体20包括滑道21，滑道21上设有第二配合部211。
其中，转动配合组件30具有使用状态和调节状态，在使用状态下，第一配合部311定位在滑道21的某一处，且与第二配合部211相互配合；在调节状态下，第一配合部311与第二配合部211解除配合，第一钳体10能够沿滑道21的延伸方向相对于第二钳体20移动；第一钳体10与第二钳体20在力的作用下张开至大于或等于预设角度时，转动配合组件30切换至调节状态；反之，第一钳体10与第二钳体20在力的作用下收拢至小于预设角度时，转动配合组件30切换至使用状态，第一钳体10与第二钳体20能够在小于预设角度的范围内转动使用。
本申请提供的钳状工具100能够通过转动配合组件30调节第一钳体10和第二钳体20的位置，以调整钳状工具100可夹持的围度范围，示例性地，可以在第一钳体10和第二钳体20收拢至小于预设角度时，也即转动配合组件30处于使用状态，用于夹持围度相对在较小范围内的物品；当需要夹持围度较大的物品时，可直接转动第一钳体10和第二钳体20，使第一钳体10和第二钳体20相对转动的角度大于或者等于预设角度，也即使转动配合组件30从使用状态转换至调节状态，在调整至合适的夹持范围后，再将转动配合组件30切换至使用状态，第一钳体10及第二钳体20具有较大夹持口，也即此时钳状工具100可用于夹持围度大小相对较大的物品；有效增加了钳状工具100的使用灵活性，且转动配合组件30的设置使得第一钳体10和第二钳体20只需要相对转动即可直接调整夹持范围，调节更便捷、灵敏，实用性高。
请再次参见图3，需要说明的是，第一钳体10包括相互连接的第一转动柄130和第一钳头140，第二钳体20包括相互连接的第二转动柄230和第二钳头240，转动配合组件30安装于第一转动柄130和第二转动柄230相对靠近第一钳头140和第二钳头240的一侧。
进一步的，在本实施例中，第一转动柄130开设有安装空间12，安装空间12沿平行于第一钳体10转动面的方向贯穿所述第一转动柄130；第二转动柄230至少部分能够设于安装空间12内，以通过转动配合组件30与第一钳体10可转动连接。
需要说明的是，第一钳体10转动面指第一钳体10与第二钳体20相对转动时所经过的区域形成的平面。
具体的，第一钳体10与第二钳体20通过转动配合组件30相互连接转动的部位包括两层第一钳体 连接部13，两层第一钳体连接部13中间具有安装空间12，第二钳体20与第一钳体10通过转动配合组件30相互连接转动的部位包括一层第二钳体连接部23，第二钳体连接部23至少部分能够设于安装空间12，以通过转动配合组件30与第一钳体10转动连接。
进一步的，在本实施例中，第一转动柄130还包括第一握持部14，第一握持部14连接于两层第一钳体连接部13相对远离第一钳头140的一侧，第二转动柄230还包括第二握持部24，第二握持部24连接于第二钳体连接部23相对远离第二钳头240的一侧。
如此设置，第一钳体连接部13和第二钳体连接部23便于安装转动配合组件30，第一握持部14和第二握持部24便于使用人员握持转动第一钳体10和第二钳体20，以便于第一钳体10和第二钳体20与转动配合组件30相互配合实现钳状工具100夹持范围的调整及使用。
可以理解，钳状工具100的第一钳体10和第二钳体20以转动配合组件30处的转动支点交错连接，以使第一握持部14和第二握持部24相对远离转动时，第一钳头140和第二钳头240能够相对靠近夹持物品。在本实施例中，第一钳体10和第二钳体20实现交错连接的方式是：第二握持部24穿过安装空间12，以使第二转动柄230和第二钳头240分别位于第一转动柄130相对背离的两侧，第一转动柄130和第一钳头140分别位于第二转动柄230相对背离的两侧，继而实现转动夹持功能。
请再次参见图1及图2，进一步的，第一钳头140和第二钳头240之间的夹持中心与滑道21的中心之间的连线垂直于滑道21的延伸方向。如此设置，钳状工具100使用过程中，更易控制第一钳头140和第二钳头240之间的张合角度和夹持力度。
请再次参见图1至图3，进一步的，滑道21的延伸形状为直线形。在本实施例中，滑道21的延伸方向与所述钳状工具100的长度方向相互垂直。如此设置，第一钳头140和第二钳头240张开和收合的朝向能够朝向使用人员的正前方，较符合大部分使用场景和使用习惯，便于控制。
可以理解，在其他实施例中，滑道21的延伸方向与钳状工具100的长度方向之间的角度也可小于或者大于90度，如此可以相对延长滑道21的延伸长度，使调节状态下钳状工具100可调节的夹持范围更大，适用性更广。
进一步可以理解的是，在其他实施例中，滑道21的延伸形状也可以是具有预设弧度的弧形，只要不影响第一钳体10和第二钳体20通过转动配合组件30可转动地连接及可转动地调节夹持范围即可。
进一步的，第一钳头140和第二钳头240相互靠近的一侧均为夹持面(图中未标示)，只要两个夹持面之间能够配合夹持物品，两个夹持面可以是平面也可以是带有齿的齿面，在本申请中不作限制。
示例性地，参见图2，在本实施例中，第一钳头140的夹持面和第二钳头240的夹持面均为带有齿的齿面，且第一钳头140与第二钳头240之间仅部分夹持面相互贴合，部分夹持面之间能够形成夹持间隙(图中未标示)，夹持间隙便于夹持管状、或者不规则形状的物品。
请再次参见图3至图6，进一步的，第一钳体10包括驱动部11，转动配合组件30包括销轴31，销轴31上设置有驱动配合部313及第一配合部311，第一钳体10与第二钳体20相对转动时，驱动部11与驱动配合部313相互配合，使得销轴31相对于第二钳体20运动，从而使得第一配合部311与第二配合部211相互配合或解除配合。
进一步的，第一钳体10上开设有第一通孔101，驱动部11包括设置在第一通孔101的驱动斜面111，驱动配合部313包括设置在销轴31周壁的驱动配合面3131。
请再次参见图7至图10，销轴31穿设第一通孔101及滑道21；当第一钳体10与第二钳体20相对转动时，销轴31在驱动部11与驱动配合部313的驱动作用下能够沿轴向运动，以使第一配合部311与第二配合部211相互配合或解除配合。换言之，第一钳体10和第二钳体20在小于预设角度内相对转动时，第一配合部311与第二配合部211处于相互配合的状态，第一钳体10和第二钳体20之间可相对转动，但不能沿滑道21的长度方向相对移动；当第一钳体10和第二钳体20相对转动角度大于或者等于预设角度时，第一配合部311与第二配合部211转换至解除配合的状态，此时第一钳体10与第二钳体20之间能够沿滑道21的长度方向相对移动，以改变钳状工具100夹持口的大小。
需要说明的是，第一通孔101纵向贯穿两层第一钳体连接部13，以使销轴31能够穿过第一通孔101在第一通孔101及滑道21内活动。
在本实施例中，驱动斜面111的数量为两个，驱动配合面3131的数量与驱动斜面111的数量相等， 在其他实施例中，驱动斜面111的数量也可根据需求相应的增加或者减少，每个驱动斜面111的延伸长度也可根据需求自由设定，驱动配合面3131的数量及长度只要能够配合驱动斜面111即可，在此不作限定。
在本实施例中，驱动斜面111为倾斜向上延伸的平面，驱动倾斜面也为倾斜延伸的平面。
在本实施例中，第一配合部311与第二配合部211之间为齿配合，滑道21为腰型的长条状滑道。示例性地，销轴31的周壁沿轴向方向依次设有第一配合部311及光轴部312，第一配合部311包括销轴31的周壁上设置的第一周齿3111，第二配合部211包括滑道21的内周壁上设置的第二周齿2111；在使用状态下，销轴31运动至第一周齿3111与第二周齿2111相啮合；在调节状态下，销轴31运动至光轴部312与第二配合部211相对应。可以理解，在其他可行的实施例中，滑道21也可以是弧形滑道或者V型等异形滑道。
需要说明的是，上述周齿是指设置在周壁上的齿，示例性地，第一周齿3111指设置在销轴31外周壁上的多个连续的齿牙，第二周齿2111是指第二钳体20上滑道21的内周壁上的多个连续的齿牙。第一周齿3111的齿牙能够与第二周齿2111的齿牙相互啮合。
进一步的，第一周齿3111由两组第一子周齿构成，两组第一子周齿相背对称设置于销轴31的周壁上。第二周齿2111也包括两组第二子周齿，两组第二子周齿分别设置于滑道21内周壁相对的两侧壁上。可以理解，第一子周齿的齿牙数量和第二子周齿的齿牙数量可以根据需求设置即可，在此不作具体限制。
可以理解，在其他实施例中，只要不影响销轴31在驱动部11与驱动配合部313的驱动作用下使得第一配合部311与第二配合部211在相互配合和解除配合之间相互转换，第一配合部311和第二配合部211之间也可以为槽柱配合，槽柱配合是指可在滑道21内壁开设卡槽，通过销轴31上的柱形部与卡槽之间进行配合。示例性地，参见图11及图12，图11为本申请其中一个实施例中钳状工具100的部分结构示意图；图12为本申请其中一个实施例中销轴31的结构示意图；第一配合部311为销轴31上的柱状部，第二配合部211为滑道21两侧的内周壁上开设有大致半圆形的卡槽，销轴31上的柱状部可在第一钳体10与第二钳体20相对转动过程中对应卡设于两个相对的大致半圆形卡槽内或者从两个相对的大致半圆形卡槽内脱离。可以理解，在其他实施例中，只要不影响与销轴31相互配合，卡槽的形状也可为半圆形或者椭圆形等。
请再次参见图7至图10，转动配合组件30还包括第一弹性件32，第一弹性件32弹性作用于第一钳体10及销轴31，第一弹性件32用于使第一配合部311与第二配合部211复位至相互配合的状态。
进一步的，第一钳体10开设有容置槽102，第一弹性件32的一端位于容置槽102内，另一端抵接于第一钳体10。可以理解，容置槽102与第一通孔101相连通，容置槽102的槽宽大于第一通孔101的底部的孔径。第一通孔101连通于容置槽102的中心，换言之，容置槽102的底壁能够环向与第一弹性件32的一端抵接。第一弹性件32为弹簧，该弹簧的周径从该弹簧的一端向另一端逐渐缩小。
转动配合组件30包括卡接件33，卡接件33与销轴31固定连接，第一弹性件32套设销轴31，第一弹性件32的一端抵接于第一钳体10，另一端抵接于卡接件33。
在本实施例中，弹簧周径较大的一端抵接于第一钳体10，弹簧周径较小的一端抵接于卡接件33。
在本实施例中，卡接件33被实施为扁圆柱形，卡接件33的中部开设有卡接槽，销轴31沿轴向在光轴部312的底部还依次设置有套接部314和卡接部315，第一弹性件32套接于套接部314，卡接件33通过卡接槽套接固定在销轴31的卡接部315。进一步的，套接部314为圆柱，卡接槽优选为腰型槽，卡接部315优选为腰型柱，且腰型柱其中一侧的宽度小于光轴部312的直径，如此设置，第一弹性件32套接在销轴31的套接部314后，该第一弹性件32的一端能够更加稳定与卡接件33的上表面相互抵持，另一端能够与容置槽102的底壁相对抵持，可以理解，容置槽102的底壁指容置槽102与卡接件33上表面相互平行并相对的一侧槽璧。
请参见图13至图17，图13为本申请提供的钳状工具100的第二个实施例的部分结构示意图；图14为本申请中钳状工具第二个实施例中销轴31的结构示意图；图15为图14中销轴31在另一视角下的结构示意图；图16为本申请中钳状工具100第二个实施例中第一安装件40的结构示意图；图17为图16中第一安装件40在另一视角下的结构示意图。本申请还提供有第二个实施例，第二个实施例与第一个实施例属于同一个发明构思，且大部分结构与第一个实施例的结构相同，区别在于：
钳状工具100还包括第一安装件40，第一安装件40固设于第一钳体10，且第一安装件40上凸设有驱动块43；第一钳体10上开设有第一通孔101，驱动块43伸入第一通孔101中；转动配合组件30包括销轴31，销轴31上设置有第一配合部311；
驱动块43相对靠近销轴31的一端设置有驱动部11，销轴31相对靠近驱动块43的一端设置有驱动配合部313；第一钳体10与第二钳体20相对转动时，驱动部11与驱动配合部313相互配合，使得销轴31相对于第二钳体20运动，从而使得第一配合部311与第二配合部211相互配合或解除配合。
可以理解，在其他实施例中，驱动部11可以设置在第一钳体10上，也可以设置在其他元件上，换言之，可以由第一钳体10配合驱动配合部313发挥驱动作用，也可以是第一钳体10之外的其他元件(例如第一安装件40)与驱动配合部313配合发挥驱动作用；也即，在本申请中，只要设置有驱动部11，且该驱动部11能够与驱动配合部313配合使第一配合部311和第二配合部211在调节状态和配合状态之间能够正常进行转换即可。
进一步的，驱动部11包括驱动斜面111，驱动配合部313包括驱动配合面3131；进一步的，驱动块43为至少两个，至少两个驱动块43环形均布；驱动斜面111与驱动配合面3131的个数与驱动块43的个数相同。
请再次参见图14至图16，在本实施例中，第一安装件40包括本体部41及设置于本体部41的两个固定耳42，第一安装件40通过两个固定耳42固定连接于第一钳体10的顶壁；本体部41靠近转轴的一侧开设有凹槽411，驱动块43由凹槽411的底壁向第二钳体20方向凸设，且驱动块43仅部分位于凹槽411内。
示例性地，在本实施例中，驱动块43为两个。两个驱动块43沿本体部41的中轴线环向对称设于本体部41的底壁，驱动斜面111为环向弯曲延伸的驱动斜面111。两个驱动斜面111的延伸曲线均具有螺旋上升规律和趋势。
此外，本申请提供的第二个实施例与第一个实施例的区别在于，销轴31未设有卡接部315，转动配合组件30也未设置有卡接件33，在本实施例中，销轴31的内部纵向开设有第一抵接槽301，第一通孔101贯穿第一钳体10位于上层的第一钳体连接部13，第一钳体10位于下层的第一钳体连接部13开设有槽口向上的第二抵接槽(图中未标示)，第一抵接槽301的槽口朝向远离第一安装件40的一侧，第二抵接槽的槽口朝向第一通孔101，第一弹性件32的一端位于第一抵接槽301内，另一端位于第二抵接槽内，换言之，第一弹性件32的一端抵接于销轴31，另一端抵接于第一钳体10，第一配合部311与第二配合部211复位至相互配合的状态是通过第一弹性件32的弹性作用实现的，第一配合部311与第二配合部211之间解除配合则是通过驱动块43与驱动配合面3131之间的联动实现的。
换言之，转动第一钳体10和第二钳体20，当第一钳体10和第二钳体20张开的角度大于或者等于预设角度时，驱动块43的驱动斜面111与销轴31的驱动配合面3131之间相互作用，能够驱动销轴31向靠近第二钳体20的方向移动，进而使第一配合部311与第二配合部211相互分离，解除配合；且销轴31还能够在向靠近第二钳体20移动的过程中压缩第一弹性件32，进而在夹持范围调整到所需范围后，第一配合部311能够跟随销轴31在第一弹性件32的弹性作用下复位，以使第一配合部311能够重新与第二配合部211卡接配合。
请参见图18至图20，图18为本申请提供的钳状工具100的第三个实施例的结构示意图；图19为图18中钳状工具在B-B截面处的剖面结构示意图；图20为本申请中钳状工具100第三个实施例中销轴31的结构示意图；本申请还提供有第三个实施例，第三个实施例与第一个实施例也属于同一个发明构思，且大部分结构与第一个实施例的结构相同，区别在于：
在本实施例中，钳状工具100还包括调节件112，调节件112设于第一钳体10，调节件112形成驱动部11；销轴31上开设有驱动配合槽3132，驱动配合槽3132形成驱动配合部313。
调节件112的一端伸入驱动配合槽3132中，第一钳体10与第二钳体20相对转动时，驱动部11与驱动配合部313相互配合，使得销轴31相对于第二钳体20运动，从而使得第一配合部311与第二配合部211相互配合或解除配合。进一步的，在本实施例中，驱动配合槽3132优选为螺旋槽或者近似螺旋槽的曲向延伸槽，换言之，只要该驱动配合槽3132能够在第一钳体10与第二钳体20相对转动时配合驱动部11使得销轴31相对于第二钳体20运动，进而驱使第一配合部311与第二配合部211能够相 互配合或者解除配合即可。
在本实施例中，调节件112为滚针；可以理解，在其他实施例中，调节件112也可被实施为其他能够伸入驱动配合槽3132内，并能够在驱动配合槽3132内运动与驱动配合槽3132共同发挥驱动作用的工件。
请再次参见图19及图20，在本实施例中，钳状工具100还包括第二弹性件50，第一钳体10上开设有安装槽103，第二弹性件50及部分调节件112位于安装槽103内，且第二弹性件50弹性作用于调节件112。如此设置，第二弹性件50能够抵持调节件112，继而保持第二弹性件50与驱动配合槽3132稳定的配合，同时也能够避免调节件112与驱动配合槽3132内壁在第一钳体10与第二钳体20相对转动过程中摩擦力过大出现断裂或者损伤的风险。可以理解，第二弹性件50可以但不限于被实施为弹簧，在其他实施例中，第二弹性件50也可以是其他具有弹性的元件，只要第二弹性件50具有的弹性作用能够驱动调节件112稳定的在驱动配合槽3132内运动，与驱动配合槽3132正常配合发挥驱动作用即可。
可以理解，在其他实施例中，钳状工具100也可不设置第二弹性件50，驱动配合槽3132底部侧端可以是开放式结构。
请参见图21至图25，图21为本申请提供的钳状工具100的第四个实施例的剖面结构示意图；图22为图21中X处的放大结构示意图；图23为钳状工具100在第四个实施例中第二钳体20的部分结构示意图；图24为第四个实施例中第二钳体20的部分结构在另一视角下的结构示意图；图25为钳状工具100在第四个实施例中配合件35及联动件34的结构示意图。本申请还提供有第四个实施例，第四个实施例与第一个实施例也属于同一个发明构思，且大部分结构与第一个实施例的结构相同，区别在于：
在本实施例中，转动配合组件30还包括联动件34及配合件35，联动件34套设销轴31，配合件35套设联动件34，且销轴31、联动件34及配合件35之间固定连接；第二钳体20朝向配合件35的表面上设置有第一端齿22，配合件35朝向第二钳体20的表面上设置有第二端齿351；在使用状态下，销轴31带动配合件35运动至第一端齿22与第二端齿351相啮合；在调节状态下，销轴31带动配合件35运动至第一端齿22离开第二端齿351。
需要说明的是，第一端齿22是指第二钳体20下表面朝向配合件35上表面(沿图示纵向方向上)凸设的一个或者多个齿牙，第二端齿351是指配合件35上表面朝向第二钳体20下表面(沿图示纵向方向上)凸设的一个或者多个齿牙。
进一步的，可以理解，销轴31、联动件34和配合件35可以一体也可以分体设置，分体设置更便于各部件的成型，一体设置更便于各部件的装配。
进一步的，销轴31包括相互连接的扩径部316及轴部317，第一弹性件32套设轴部317，且第一弹性件32的一端抵接于扩径部316，另一端抵接于第一钳体10。需要说明的是，在本实施例中，驱动部11设置于扩径部316上，驱动部11为位于扩径部316内侧的内螺旋面。
请参见图26至图36，本申请还提供有第五个实施例，第五个实施例与第一个实施例也属于同一个发明构思，且大部分结构与第一个实施例及第二个实施例的结构相同，区别在于：
请再次参见图26及图27，在第五个实施例中，第一转动柄130和第一钳头140分体成型，第一钳头140可转动地连接于第一转动柄130，且第一钳头140可活动地连接于第二钳体20；其中，第一转动柄130设置有传动部104，第一钳头140设置有传动配合部105，第一钳头140通过传动部104与传动配合部105的配合可转动地连接于第一转动柄130；转动第一转动柄130，传动部104能够通过传动配合部105推动第一钳头140在第二钳体20上移动。
如此设置，能够使第一钳头140的设计更加多样化、安装更加方便，进而能够使第一钳头140和第二钳头240的夹持方式和夹持方向更加灵活，以适应多种环境下的夹持需求。
进一步的，为了保证第一钳头140在第二钳体20上移动稳定性，在其中一个实施例中，第二钳体20开设有限位滑槽106，第一钳头140凸设有与限位滑槽106相配合的滑动块107，转动第一转动柄130，第一钳头140能够通过滑动块107沿限位滑槽106的延伸方向滑移。
如此设置，限位滑槽106能够提供导向作用，限位滑槽106配合滑动块107能够有效提高第一钳头140在第二钳体20上移动的稳定性以及移动方向的精确性。
可以理解，限位滑槽106的延伸形状和滑道21的延伸形状相同。如此，能够使第一转动柄130、第一钳头140、第二转动柄230及第二钳头240之间的配合更加顺畅、协调。
进一步的，在本实施例中，第二钳体20的第二转动柄230和第二钳头240一体成型设置。如此便于第二钳体20的加工。
进一步需要说明的是，限位滑槽106为开设于第二钳头240表面的盲槽，限位滑槽106相对的两端贯穿第二钳头240的两侧，如此,便于第一钳头140的滑动块107安装至限位滑槽106中。
可以理解，在其他实施例中，限位滑槽106也可以为开设于第二钳头240的通槽，如此设置时，限位滑槽106的延伸长度小于第二钳头240的宽度。
进一步的，传动部104和传动配合部105中的一者被配置为凸块1041，另一者被配置为凹槽1051。如此，凸块1041和凹槽1051易加工成型，凹凸配合的方式均较为简便可靠。
具体的，在本实施例中，传动部104为凸设于第一转动柄130端部的凸块1041，传动配合部105为开设于第一钳头140的凹槽1051。为了保证凸块1041和凹槽1051之间转动配合的顺畅性，凸块1041与凹槽1051连接的外周壁为弧形，凹槽1051具有与凸块1041外周壁弧度相匹配的内周壁。
进一步需要说明的是，第一钳体10和第二钳体20实现交错连接的方式是：将第一转动柄130与所述第二钳体20相连，再将第一钳头140与第一转动柄130相连，以使第二转动柄230和第二钳头240分别位于第一转动柄130相对背离的两侧，第一转动柄130和第一钳头140分别位于第二转动柄230相对背离的两侧。
请再次参见图26至图28，在本实施例中，第二钳体20的滑道21的延伸方向与钳状工具100的长度方向之间具有夹角，该夹角的范围小于90度或者大于90度。如此设置，可以相对延长滑道21的延伸长度，使调节状态下钳状工具100可调节的夹持范围更大，适用性更广。换言之，第二钳体20的滑道21能够倾斜延伸，滑道21的延伸长度相比于第一个实施例中钳状工具100滑道的延伸长度更长，使得钳状工具100在调节状态下可调节的夹持范围更大，钳状工具100的使用更加灵活，适用范围更广。
可以理解，在其他实施例中，滑道21的延伸形状也可以是具有预设弧度的弧形，只要不影响第一钳体10和第二钳体20通过转动配合组件30可转动地连接及可转动地调节夹持范围即可。
请再次参见图1，需要说明的是，在该实施例中，第一钳头140和第二钳头240张开和收合的朝向能够朝向使用人员的侧前方，该钳状工具100能够从侧方伸入一些狭窄不易进入的空间中夹持所需处理的物品。
请再次参见图29至图36，进一步的，在本实施例中，销轴31的底部开设有第一抵接槽301，卡接件33开设有第三抵接槽302，第三抵接槽302的底壁凸设有配合凸起331，销轴31通过配合凸起331与第一抵接槽301的插接与卡接件33相连；第一弹性件32套设于销轴31的套接部314，第一弹性件32的一端能够抵接于销轴31，另一端能够抵接于第三抵接槽302的底壁；如此设置，销轴31在向靠近第二钳体20移动的过程中压缩第一弹性件32，第一配合部311就能够跟随销轴31在第一弹性件32的弹性作用下复位，使第一配合部311能够重新与第二配合部211卡接配合。
本申请提供的钳状工具100能够通过转动配合组件30转换钳状工具100的可夹持的围度范围，示例性地，可以在第一钳体10和第二钳体20收拢至小于预设角度时，也即转动配合组件30处于使用状态时，使得钳状工具100用于夹持围度相对在较小范围内的物品；当需要夹持围度较大的物品时，可直接转动第一钳体10和第二钳体20，使第一钳体10和第二钳体20相对转动的角度大于或者等于预设角度，也即，使转动配合组件30从使用状态转换至调节状态，在调整至合适的夹持范围后，再将转动配合组件30切换至使用状态，钳状工具100可用于夹持围度大小相对较大的物品；有效增加了钳状工具100的使用灵活性，且转动配合组件30的设置使得第一钳体10和第二钳体20只需要相对转动即可直接调整夹持范围，调节更便捷、灵敏，实用性高。
以上所述实施方式的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施方式中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
本技术领域的普通技术人员应当认识到，以上的实施方式仅是用来说明本申请，而并非用作为对本申请的限定，只要在本申请的实质精神范围内，对以上实施方式所作的适当改变和变化都落在本申请要求保护的范围内。
