Description

一种单手使用的快速棘轮扳手 技术领域
本发明属于五金工具技术领域，具体为一种单手使用的快速棘轮扳手。
背景技术
棘轮扳手是一种正转过程带动螺帽转动、反转过程棘爪相对螺帽滑动且螺帽不动的扳手工具，对于现有的双棘爪棘轮扳手，棘爪之间设置张机头，使用时，在一手握着扳手手柄的同时，还需要另一手辅助转动张机头，从而使张机头分别推开左侧或右侧的棘爪，使其中一个棘爪处于工作位置，对于这样的操作方式，势必会不利于操作棘轮扳手，影响工作效率。
发明内容
本发明的目的在于提供一种单手使用的快速棘轮扳手，使用者在手握扳手的同时就可以随时调整每个棘爪的工作状态，且一手即可完整，操作方便，有利于提高工作效率。
为实现上述目的，本发明提供如下技术方案：一种单手使用的快速棘轮扳手，包括手柄、扳手头、套孔、左棘爪、右棘爪、张机头，其中扳手头设置在手柄的顶端，扳手头上设置套孔，且在套孔内靠近手柄的位置设置左棘爪和右棘爪，棘爪可绕其后端偏转，且在棘爪和套孔壁面之间设置弹簧，所述张机头设置在左棘爪和右棘爪之间。所述张机头安装在控制机构顶端，该控制机构安装在手柄上，且在控制机构末端设置推进头，通过推动推进头，可以使控制机构前后移动，使张机头位于前后两个位置；所述左棘爪和右棘爪的相邻侧分别错位设置一个碰触头，张机头位于前后两个位置时，可分别触碰其中一个触碰头并将相应的棘爪向外顶开，另一个棘爪处于工作位置。
在上述技术方案中，用于控制左棘爪和右棘爪的张机头安装在控制机构的顶端，该控制机构可前后移动，进而控制张机头向前或向后移动，而张机头在前移或后移后，会独立碰触位于棘爪上的其中一个碰触头，张机头推动该触碰头向外偏移，从而使该触碰头对应的棘爪向外偏移，另一个棘爪自由处于工作位置，此时便可以利用处于工作位置的棘爪来转动螺帽；在握着手 柄的同时，只需反向移动推进头，即可使张机头移动并推开另一个棘爪，此时第一个棘爪处于工作位置，可以对螺帽进行反向转动，因此在使用该扳手时一手便可以对棘爪进行调整，从而满足螺帽的正向或反向转动。
优选地，所述手柄内部设置内孔，控制机构安装在内孔中，在手柄与扳手头的连接处设置通孔，该通孔连通内孔和套孔，且控制机构穿过该通孔。将控制机构安装在手柄中部的内孔中，可以保护控制机构，防止控制机构意外损坏，也可以避免控制机构内部积累灰尘等影响控制机构灵活运动的物质。
优选地，在手柄侧壁设置连通内孔的活动孔，所述推进头穿过活动孔并位于手柄外侧，人们在手握手柄时，手指可以方便地推动推进头，这不仅有利于操作，而且可以使手一直处于最佳握持状态。
优选地，所述控制机构包括顶轴和定位机构，其中张机头安装在顶轴的顶端，通过定位机构可以固定张机头的位置，该扳手的使用分为两个状态，一是逆时针转动，一是顺时针转动，在一个使用状态的整个过程中，需要两个棘爪处于稳定的状态，即张机头的位置相对不变，设置定位机构可以对张机头的位置进行定位，使该扳手的使用更加方便。
优选地，所述定位机构为棘轮伸缩机构，包括按压头、转动头、导向条、复位弹簧，其中转动头连接顶轴，所述复位弹簧套装在顶轴上，其中复位弹簧一端顶着手柄本体，另一端顶着设置在顶轴上的挡件；所述推进头设置在按压头上。采用棘轮伸缩机构，整个控制机构的调整就只有一个推动推进头的动作，操作简单，不易出现误操作。
进一步，所述导向条设置在内套内壁中，该内套安装在内孔中，且其前端设置供顶轴穿过的孔洞，所述按压头和转动头插入定位内套内。将棘轮伸缩机构内的导向条设置在内套内部，并将压头、转动头等套装在内套中，这有利于棘轮伸缩机构各部件的安装与拆卸，方便该棘轮扳手的批量生产以及后期的拆装维修。
进一步，在手柄上设置连通内孔的螺孔，并在螺孔内安装用于固定内套的定位螺栓，通过拧紧定位螺栓，可以将内套紧紧地固定在内孔中，避免内套晃动。

具体实施方式
以下将配合附图及实施例来详细说明本申请的实施方式，借此对本申请如何应用技术手段来解决技术问题并达成技术功效的实现过程能充分理解并据以实施。
请参阅图1-3和图6，本发明提供一种实施例：该实施例以现有棘轮扳手为基本体，扳手头2设置在手柄1的顶端，扳手头2正面设置凹槽，且在凹槽前部设置套孔3，且凹槽内靠近手柄1的位置设置左棘爪41和右棘爪42。在凹槽底面后部设置定位孔21，左、右棘爪的末端设置转轴，并通过转轴安装在定位孔21中，且两个棘爪可以绕着各自的转轴偏转，另外，在棘爪和凹槽壁之间设置弹簧7，所述张机头6设置在左棘爪41和右棘爪42之间。张机头6安装在顶轴81顶端，该顶轴81安装在手柄1上，且在顶轴81末端设置定位机构，该定位机构上设置推进头5，通过推动推进头5，可以使控制机构8前后移动，并使张机头6固定停在前方或后方；所述左棘爪41和右棘爪42的相邻侧分别错位设置一个碰触头400，且左侧的碰触头400比右侧的碰触头400靠前，当张机头6位于前方时，会推动左侧的碰触头400，并使左棘爪41向左偏移，此时右棘爪42处于工作位置；当张机头6位于后 方时，会推动右侧的碰触头400，并使右棘爪42向右偏移，此时左棘爪41处于工作位置。
另外，手柄1内部设置内孔10，该内孔10贯穿整个手柄1，且在手柄1末端设置塞子，用于密封内孔端口，防止异物进入内孔10。顶轴81和定位机构安装在内孔10中，在手柄1与扳手头2的连接处设置通孔，该通孔连通内孔10和套孔3，且顶轴81穿过该通孔。且在手柄1侧壁设置连通内孔10的活动孔101，所述推进头5穿过活动孔101并位于手柄1外侧，人们在手握手柄1时，手指可以方便地推动推进头5。
所用定位机构为棘轮伸缩机构(即自动圆珠笔的伸缩机构)，如图4和图5所示，包括按压头82、转动头83、导向条84、复位弹簧85，其中转动头83连接顶轴81，所述复位弹簧85套装在顶轴81上，其中复位弹簧85一端顶着手柄1本体，另一端顶着设置在顶轴81上的挡件86；所述推进头5设置在按压头82上。采用棘轮伸缩机构，只需推动推进头5这一种动作，就可以调整推进头5的位置，操作简单，不易出现误操作。
在棘轮伸缩机构中，导向条84设置在内套87内壁中，该内套87安装在内孔10中，且其前端设置供顶轴81穿过的孔洞，所述按压头82和转动头83插入定位内套87内。将棘轮伸缩机构内的导向条84设置在内套87内部，并将压头82、转动头83等套装在内套87中，这有利于棘轮伸缩机构各部件的安装与拆卸，方便该棘轮扳手的批量生产以及后期的拆装维修。
为保证内套87的稳定性，在手柄1上设置连通内孔10的螺孔，如图3和4所示，并在螺孔内安装用于固定内套87的定位螺栓9，且在内套的前端设置环形凹槽，定位螺栓9的端部顶触该环形凹槽，用于防止内套87后移。
工作原理：以顺时针转动扳手为例，将套孔3套在螺帽11上，推动推进头5，使张机头6后移，此时右棘爪42向右偏离，左棘爪41接触螺帽11，逆时针推动手柄1，左棘爪41紧顶螺帽11侧壁，并使螺帽11转动，当逆时针回转手柄1时，螺帽11保持不动，左棘爪41相对划过螺帽11侧壁，进而可以继续顺时针转动扳手，继续转动螺帽11。
本发明采用设置在手柄内的控制机构来控制张机头的位置，进而来控制两个棘爪的位置，从而使扳手可以分别适用于拧紧和松动螺帽的过程，使用 者在手握手柄的同时，只需通过手指推动推进头就可以对张机头的位置进行调整，而且可以对张机头进行定位，因此使用起来十分方便，实现单手使用棘轮扳手的目的，给工作带来便利。
