Description

一种新型多功能折叠工具 技术领域
本发明涉及一种五金工具，具体地涉及一种新型多功能折叠工具，特别是涉及一种新型折叠螺丝刀。
背景技术
作为一种常用的五金工具，螺丝刀给人们的生活和工作带来了极大的方便，节省了劳动力成本，提高了劳动效率。根据螺丝刀的刀头形状，螺丝刀一般又可分为一子螺丝刀和十字螺丝刀，在日常的工作和生活中，人们会根据螺丝钉头的形状来选择使用什么样的螺丝刀。
最早期的螺丝刀是按不同型号规格制成的单个螺丝刀，这样就造成工作时要携带大量不同型号规格的螺丝刀，使用很麻烦。目前市场上有多种组合式螺丝刀，配有多种不同型号的刀头，在使用时根据需要挑选合适的刀头装上，使用时存在刀头更换麻烦，易丢失而且刀头容易松动的问题，并且在换头时很容易由于操作失误把刀头掉到工作环境中，尤其是在机电器械维修中，掉下去的刀头会使电路板上的元器件短路，从而造成巨大的经济损失。为了克服这一缺点，有人设计了一种刀头和手柄连接在一起的螺丝刀，在使用时通过旋转手柄上不同的刀头来调配要使用的刀头，但是刀头在使用时无法将刀头进行固定，刀头可能会由于用力不均通过原路径反折回刀柄，使用起来较麻烦，通用性降低。由于刀头无法固定在某一固定位置，在拧螺丝用力不能过大，从而导致螺丝拧不紧或卸不下来，有时甚至会碰伤手部或造成事故。
发明内容
本发明的目的是克服现有技术的不足，设计出一种新型多功能折叠工具。
为达到上述目的，本发明所采用的技术方案是：
一种新型多功能折叠工具，包括刀壳、固定片、固定轴、刀头、扣环，所述固定片固定在刀壳的内壁上，固定轴分别固定在固定片的上下两端，扣环的一端套在固定轴上，刀头通过扣环与固定轴活动连接，还包括刀头槽片、主动锁片、转轴、手动拨轮、凸轮片，所述刀头槽片固定在扣环上，刀头槽片上设置有与主动锁片配合来固定刀头的卡槽，凸轮片上设置有相对于凸轮片的中心位置对称的两个弧形卡槽，主动锁片为左右两端对称的“π”形，主动锁片上部的左右两端固定在固定片上，下部的左右两端分别穿过在手动拨轮和凸轮片的弧形卡槽并卡在固定片的滑槽内，手动拨轮与凸轮片分别套在转轴的两端，转轴与固定片活动连接。
进一步地，还包括主动锁片固定片，所述主动锁片固定片为“工”字形或逆时针旋转90°的“H”形，主动锁片固定片的左右两端固定在固定片上，主动锁片为左右两端对称的“π”形或“几”字形，主动锁片的上部夹在两个主动锁片固定片之间，下部的左右两端分别穿过在手动拨轮和凸轮片的弧形卡槽并卡在固定片的滑槽内。
一种新型多功能折叠工具，包括刀壳、固定片、固定轴、刀头、扣环，所述固定片固定在刀壳的内壁上，固定轴分别固定在固定片的上下两端，扣环的一端套在固定轴上，刀头通过扣环与固定轴活动连接，还包括刀头槽片、锁紧件、转轴、手动拨轮、凸轮片，所述刀头槽片固定在扣环上，刀头槽片上设置有与带弯钩的锁紧件配合来固定刀头的卡槽，凸轮片上设置有相对于凸轮片的中心位置对称的两个弧形卡槽，锁紧件的弯钩穿过固定片的滑槽分别卡在手动拨轮和凸轮片的弧形卡槽内，手动拨轮与凸轮片分别套在转轴的两端，转轴与固定片活动连接。
进一步地，所述多功能折叠工具为折叠螺丝刀。
进一步地，所述扣环具有两个端部，通过将相邻装配的刀头设置在所述扣环的不同端部，使得相邻装配的刀头分别位于所述固定轴的两侧，从而使相邻装配的刀头之间存在间隙，以便操作时取出所述刀头。
进一步地，手动拨轮与凸轮片的中央位置分别设置有孔，该孔的形状被设置成与转轴的横截面形状相同并且适于将转轴装配到孔中，在转轴上设置有套管，该套管的长度被设置成使手动拨轮与凸轮片分别位于转轴的两端。
进一步地，所述锁紧件为带弯钩的开口矩形钢丝条或钢丝杆，所述钢丝条或钢丝杆为2-4mm。
进一步地，所述转轴为棱柱体。
进一步地，所述刀头包括一字刀头、十字刀头、内六角刀头、各种异型螺丝刀头、开瓶器、小刀、锉刀、开口扳手、锥子、剪刀、钻头、钢锯，刀头的规格大小各不相同。
进一步地，所述刀头的锁紧角度为90°、135°或180°。
进一步地，所述刀头中的每个能够同时以不同的锁紧角度锁紧。
进一步地，所述刀头与扣环为一体的。
进一步地，所述刀头为可拆卸替换刀头。
本发明的积极有益效果：
本发明结构简单、使用携带方便，通过在扣环上焊接刀头槽片，用手旋转手动拨轮，以带动转轴和凸轮片旋转，使主动锁片或锁紧件卡在刀头槽片的卡槽内，将刀头固定在某一角度，避免刀头因用力不均按原路径反折回刀柄。
刀头能够固定在多个角度，适用性更广，使用更加方便，且安全性较高。
刀头种类较多，且规格大小不同，且刀头损坏后可更换。
