Description

木工虎钳 技术领域
本发明涉及夹具技术领域，尤其是涉及一种木工虎钳。
背景技术
木工在进行作业时，经常需要将工件夹持在工作台上。比如，将工件夹持在木工虎钳上。常见的木工虎钳在使用时，在钳口将工件夹紧后，往往通过手动的方式拉动相关部件继而实现锁止。其缺陷在于：操控较为繁琐，且极为费力。
发明内容
本发明的目的是提供一种木工虎钳，它具有操作方便、轻松的特点。
本发明所采用的技术方案是：木工虎钳，包括机架，该机架上设有夹具组件以及和该夹具组件相配的连杆，该连杆的前端铰连在该机架上，
所述连杆的后端设有向上延伸的延伸架，有一锁紧件的前端铰连在该延伸架的上端，有一翘板的中部铰连该延伸架的上端部且位于该锁紧件的下方，该锁紧件上设有配合孔，且该锁紧件配有使其具有顺时针旋转趋势的扭簧，该机架的后部设有向下延伸的锁紧杆，该锁紧杆穿设在该配合孔内，该翘板的后端和该锁紧件相配；
所述连杆的后端连接有向下延伸的支架，且该支架相对于该连杆不可顺时针旋转，有一踏板的中部铰连在该支架的下端，该踏板的前端连接有一连动杆，该连动杆上端连接该翘板的前端。
所述连动杆配有使其具有向上位移趋势的压簧。
所述翘板的后端设有支撑轮，该支撑轮支撑在该锁紧件的下方。
所述延伸架上固定有一向上延伸的可伸缩件，该可伸缩件的上端铰连有一摆动臂，该锁紧件铰连在该摆动臂上。
所述可伸缩件包括一螺套和一螺接在该螺套内的螺杆。
采用上述结构后，本发明和现有技术相比所具有的优点是：操作方便、较为轻松。本发明的木工虎钳在使用时，通过脚跟部向下踩踏板的后部，可带动连杆顺时针旋转，对夹具组件实施锁紧，且连杆无法自行复位；当需要连杆复 位时，仅需用脚掌部向下踩踏板的前部，配合孔和锁紧杆即会失去相互之间的锁止，连杆会自行复位，极为方便和轻松。
附图说明
下面结合附图和实施例对本发明进一步说明：
图1是本发明的实施例的木工虎钳的立体示意图(以下各图相对于图1均进行了放大)；
图2是本发明的实施例的木工虎钳的局部图(局部剖视)；
图3是图2的A部放大图；
图4是本发明的锁紧件的主视图(局部剖视)；
图5是本发明的翘板的主视图；
图6是本发明的实施例的木工虎钳的部分部件的连接图；
图7是本发明的实施例的包含有压簧的木工虎钳的部分部件的连接图；
图8是本发明的实施例的木工虎钳的部分部件的右视图；
图9是图8的B部放大图。
具体实施方式
实施例，见图1至图9所示：木工虎钳，包括机架10。该机架10上设有夹具组件20以及和该夹具组件20相配的连杆30，该连杆30的前端铰连在该机架10上。即，该连杆30顺时针旋转后，对该夹具组件20实施锁紧；反之，该连杆30逆时针旋转后，该夹具组件20解锁。当然，该连杆30最好配有使其逆时针旋转的复位弹簧(图上未示出)。
进一步的讲：
该连杆30的后端设有向上延伸的延伸架31。即，从侧面看，该连杆30以及延伸架31可以呈“L”字形，且该延伸架31可以为一筒状。有一锁紧件40的前端铰连在该延伸架31的上端，有一翘板50的中部铰连该延伸架31的上端部且位于该锁紧件40的下方。同时，该锁紧件40上设有配合孔41，且该锁紧件40配有使其具有顺时针旋转趋势的扭簧42。该机架10的后部设有向下延伸的锁紧杆60，该锁紧杆60穿设在该配合孔41内。以及，该翘板50的后端和该锁紧件40相配。即，该翘板50的后端顶在该锁紧件40的下方。在一般情况下，该扭簧42使该锁紧件40趋于非水平状态，从而该配合孔41卡紧该锁紧杆60使该锁紧件40无法上下移动，表现为该连杆30无法旋转，从而实现锁止；反 之，一旦该锁紧件40在外力作用下趋于水平，则该配合孔41不再卡紧该锁紧杆60，该锁紧件40即可上下自由移动，表现为该连杆30能够自由旋转，从而实现解锁。
该连杆30的后端连接有向下延伸的支架70，且该支架70相对于该连杆30不可顺时针旋转。比如，该连杆30上固定有向右延伸的限位杆，该支架70上设有条形且在上下方向上进行延伸的限位孔，该限位杆穿在该限位孔内，且该限位杆在上下方向上具有一定的活动余量。有一踏板80的中部铰连在该支架70的下端，该踏板80的前端连接有一连动杆81，该连动杆81上端连接该翘板50的前端。
这样，由于在一般情况下，该锁紧杆60对该锁紧件40实施了锁止，故而仅需用脚根部向下踩踏该踏板80的后部，该连杆30即会顺时针旋转且无法自行复位，故而对该夹具组件20实施了锁紧；当需要释放该夹具组件20时，仅需用脚掌部踩踏该踏板80的前部，该连动杆81即会带动该翘板50的前端向下移动，该翘板50的后端上移，顶着该锁紧件40趋于水平，该配合孔41和该锁紧杆60无法再行锁止，该连杆30即会立即顺时针旋转，对该夹具组件20实施解锁。
优化的：
该连动杆81配有使其具有向上位移趋势的压簧82。即，该压簧82能够使该踏板80及时复位，且使该翘板50的后端始终趋向下行，确保该锁紧杆60对该锁紧件40的锁止。
该翘板50的后端设有支撑轮51，该支撑轮51支撑在该锁紧件40的下方。这样，确保操控的顺畅。
继续优化：
该延伸架31上固定有一向上延伸的可伸缩件90，该可伸缩件90的上端铰连有一摆动臂93，该锁紧件40铰连在该摆动臂93上。本实施例中，该可伸缩件90可以包括一螺套91和一螺接在该螺套91内的螺杆92。此时，该螺套91的上端可以铰接在该93摆动臂上、该翘板50的中部可以铰连在该延伸架31上。这样，当该配合孔41的孔径因磨损而变大后，可以通过调整该可伸缩件90的长度，使该锁紧件40和水平面能够具有更大的夹角，确保该锁紧杆60能够始终较好的锁止该配合孔41。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
