紧固件旋动工具的插接件
                  发明领域
本发明总体涉及工具和其中所用的部件，更具体而言，涉及沿顺时针和/逆时针方向旋动紧固件的工具。
                   背景
多年来，工具的发展已经由于要实现各种目的而得以显著改进。众所周知，即使是手动工具也有了许多改进，使得其对于使用者而言更加理想和灵活。例如，现在有各种能够实现多种功能的手动工具。
更具体而言，美国伊利诺斯州芝加哥市的Eazypower公司(Eazypower Corporation of Chicago，Illinois)销售一种可为使用者提供各种不同选择的手动螺丝刀。这种螺丝刀具有一个一端带有插接件或套管的手柄，该插接件或套管中装入一根插管，该插管在其对置两端中各套装一个可以颠倒换用的螺丝刀尖头件。采用这种结构，可以以允许有选择地使用各个螺丝刀尖头件的方式将插管***插接件或套管。
当然，每个可以颠倒换用的螺丝刀尖头件在其对置两端上各有一个单独的刀尖头。这样，无论何时当螺丝刀尖头件从插管部件的外露端部伸出时它们都是可以颠倒换用的，可以根据当时的需要，使用尖头件上的任一刀尖头。由于此种结构，拥有这种单一手动工具的使用者可以容易地采用四种不同的刀尖头。
如上面所提到的，此种类型的工具通常具有一个多功能的插接件或套管。位于此种工具的手柄一端的插接件或套管必须能够传递外加在手柄上的转矩，由此将旋转运动传递给螺丝刀尖头件，此外，除了当必须卸下插管以使用另一个可以颠倒换用的螺丝刀尖头件上的某个刀尖头时，该插接件或套管必须能将夹持螺丝刀尖头件的插管固定在手柄内。为了达到这些目的，插管和插接件或套管通常以相当复杂的方式形成。
更具体而言，手动螺丝刀的插接件或套管通常在其内的轴向开孔中包括一对完全对置的槽，而该轴向开孔是用来装入插管的。该插接件或套管同时也包括一对完全对置的小孔，它们与相应的槽偏移90度。至于该插管，它通常设有一对可装在套管两个槽中的完全对置的凸出物和一个可装在套管两孔中任一孔内的弹簧制动球。
虽然该装置工作相当良好，但仍有几个非常重要的缺点。首先，由于频繁卸下和重新插上插管以使用可颠倒换用的螺丝刀尖头件上的各种刀尖头，所以套管中的槽或插管上的凸出物可能随时间的推移而损坏。凸出物比较小，槽也比较小，因此凸出物或槽的任何操作可使其以后无法通过安置套管的手柄将转矩传递到与紧固件啮合的尖头件。其次，由于相对于套管和手柄要频繁卸下和重新插上插管，因此该弹簧制动球也可能受到损坏。此外，用于“四合一”螺丝刀的插管不可能满足“二合一”螺丝刀的使用需要。
鉴于上述情况，仍然需要提供一种沿顺时针和/或逆时针方向旋动紧固件的令人完全满意的工具。需满足的主要要求包括能够不失效地直接而可靠地传送转矩，而且还能够利用一种机构将紧固件啮合部件可以脱开地固定在转动施加部件内，该机构不会暴露和损伤而同时具有足够的运动自由度来完全实现其预定样式的功能。此外，该工具应当能够以比较低的成本制造而其部件的形成方式应当使其具有极长的寿命。
本发明旨在克服一个或多个上述问题并达到一个或多个最终目的。
                    发明概述
本发明的主要目的是提供一种工具，这种工具可以优选地采取沿顺时针和/或逆时针方向旋动紧固件的手动工具的形式。本发明的另一目的是提供这样一种工具，该工具具有一个插接件或套管，用于以这样一种方式可脱开地固定一个紧固件配合部件，即：以直接而可靠的方式施加转动，同时用一个隐藏而受到保护的可膨胀/可压缩弹簧机构可脱开地夹住该紧固件配合部件。本发明的又一个目的是提供这样一种插接件或套管，它用于一种沿顺时针和/或逆时针方向旋动紧固件的手动工具。
因此，本发明旨在通过提供一种沿顺时针和/或逆时针方向旋动紧固件的工具来达到这些目的。该工具包括以啮合方式配合紧固件的部件，以便于可依其本身的转动而顺时针或逆时针地旋动紧固件。该工具同时包括用于将转动施予紧固件配合部件的部件，由此将旋动运动沿顺时针和/或逆时针方向施予紧固件。采用这种结构，该工具还包括与运动施加部件成操作关系地可脱开地固定该紧固件配合部件的部件。
更具体地说，该固定部件包括可以以直接而可靠的方式将转动从运动施加部件传递给紧固件配合部件的部件，它还包括可膨胀/或可压缩的弹簧机构，其用于可以脱开地夹住该紧固件配合部件。
在示范的实施例中，该固定部件包括一个插接件或套管，该插接件或套管具有一个带外部弹簧膨胀室的外表面，该膨胀室用于容纳和调节可膨胀/或可压缩弹簧机构的膨胀。插接件或套管有利地在一端有一个轴向延伸孔而在另一端封闭，以便于限制紧固件配合部件的轴向***程度。此外，插接件或套管优选地具有一个形成有基本上沿轴向延伸的细花键槽的外表面，其通过与手柄的内表面咬合而相互配合构成该运动传递部件的至少一部分。
在一个实施例中，在一端具有一个基本上呈六角形的轴向延伸孔的插接件构成运动传递部件的至少一部分。在另一个实施例中，插接件在一端具有一个轴向延伸孔，该孔具有一个基本上呈圆筒形的第一部分和一个基本上呈六角形的第二部分。
在一个高度优选的实施例中，该工具呈一种手动工具的形式，而转动施加部件呈手柄形式，为了通过该手柄施加转矩而将其紧握。因此手柄适合于通过插接件或套管而手动地施加转动，该***件或套管有利地包括一个基本上圆筒形的手柄插接件，其适合于以直接而可靠的方式传递手动施加地手柄转动。此外，该插接件优选地具有一个带径向切口的外表面，该径向切口形成外部弹簧膨胀室，该外部弹簧膨胀室用于容纳和调节位于其中的可膨胀/或可压缩弹簧机构。
关于插接件或套管，在与轴向延伸孔对置的端部处封闭有利于隔离并预防紧固件配合部件与手柄配合。因而也可以理解，在插接件的外表面上设置基本上沿轴向延伸的细花键槽以便如上所述地啮合手柄，这样就构成运动传递部件的一部分。至于外部弹簧膨胀室，将其设置在基本上位于插接件或套管两端之间但更靠近具有轴向延伸孔的端部的某点处是有利的。
此外，外部弹簧膨胀室有利地具有一个面向外部的光滑表面，而可膨胀/可压缩的弹簧机构包括一个适合于安置在外部弹簧膨胀室内的制动件。该制动件包括一个设置在穿过该面向外部的光滑圆筒形表面的孔中的球和一个围绕该圆筒形表面设置的带，该带限制了孔中的球。由于本发明用在手动工具中，包括球和带的制动件全都被限制在手柄内并受到保护，因而使得它们的膨胀和压缩绝不会由于外部弹簧膨胀室而受到限制。
在一个实施例中，插接件一端的轴向延伸孔基本上呈六角形而构成运动传递部件的至少一部分。采用这种结构，紧固件配合部件至少有一部分为基本上六角形，以便以啮合方式装入基本上呈六角形的孔中。
更具体而言，插接件或套管的轴向延伸孔最好在其整个长度上都基本上呈六角形。紧固件配合部件最好包括一个可以颠倒换用的螺丝刀尖头件，该螺丝刀尖头件在其对置两端上具有第一和第二刀尖头。采用这种结构，可以颠倒换用的螺丝刀尖头件还具有一个位于第一和第二刀尖头之间的柄部，该柄部构成基本上呈六角形的部分。
在另一个实施例中，插接件或套管的轴向延伸孔具有一个基本上呈圆筒形的部分和一个远离该端的基本上呈六角形的部分。所述基本上呈六角形的部分还形成运动传递部件的一部分。采用这种结构，紧固件配合部件还具有基本上呈六角形的一部分，它以啮合方式装入所述孔的基本上呈六角形的部分中并与其配合。
更具体而言，紧固件配合部件包括一个基本上呈圆筒形的插管以作为其一部分，在该插管对置的每一端具有一个基本上呈六角形的轴向延伸孔。采用这种结构，紧固件配合部件在其插管的每个轴向延伸孔中也包括一个可以颠倒换用的螺丝刀尖头件，该尖头件在其对置两端具有第一和第二刀尖头而在两尖头之间具有中间柄部。
关于该实施例，每个可以颠倒换用的螺丝刀尖头件的柄部还基本上为六角形，该柄部的长度当完全***管中时足以从插管中凸出。结果，该插管适用于***该插接件的轴向延伸孔中，而使得可颠倒换用的螺丝刀尖头件的柄部凸出部分与该插接件中孔的基本上呈六角形的部分相配合。
结合附图考虑下述说明书，可以清楚本发明的其它目的、优点和特点。

               优选实施例详述
在给定的附图中，首先参照图1，标号10总体表示一种沿顺时针和/或逆时针方向旋动紧固件的工具。可以理解，工具10包括图示实施例中的手动工具，它包括用于以啮合方式配合紧固件的部件12，以便随转动而顺时针和/或逆时针地旋动紧固件，同时该工具也包括手柄形式的部件14，用于将转动手动地施加给紧固件配合部件12，以便沿顺时针和/或逆时针方向施予紧固件旋动转动。如图1-4中所示，该工具10包括部件16，该部件以基本上呈圆筒形手柄插接件的形式而与手柄14成操作关系地可脱开地固定紧固件配合部件12。
如将从图2-4中所理解的，基本上呈圆筒形的手柄插接件16非常适合于以直接而可靠的方式将手动施予手柄14的转动传递给紧固件配合部件12。也可以看出，插接件16包括可膨胀/可压缩的弹簧机构18，后者用于可脱开地夹住紧固件配合部件12。更具体地说，插接件16具有一个带径向切口22的外表面20，该径向切口22形成一个外部弹簧膨胀室24以用于容纳和调节其中可膨胀/可压缩弹簧机构18的膨胀。
如图2中最清楚地示出，插接件16同时在一端28具有一个沿轴向延伸的孔26而在另一端30封闭，以便可以脱开地装入紧固件配合部件12而又避免后者与手柄14相配合。插接件16的轴向延伸孔26具有一个基本上圆筒形的部分32和一个远离端部28的基本上六角形的部分34，以便与手柄14结合而形成运动传递部件的一部分，而紧固件配合部件12具有一个基本上六角形的部分36(见图2)，以便于以啮合方式装入孔26的基本上呈六角形的部分34中。在图1至4例示的实施例中，可以理解，紧固件配合部件12包括一个基本上呈圆筒形的细长管38及一对总体由40和42表示的可颠倒换用的螺丝刀尖头件。
具体参照图2，该基本上圆筒形的插管38具有轴向延伸孔44和46，它们适合于在各对置端部48和50中基本上呈六角形，使得可颠倒换用的螺丝刀尖头件40和42被设计成置于其中。可以颠倒换用的螺丝刀尖头件40和42各在其对置两端上具有第一和第二刀尖头40a、40b和42a、42b，同时还在两端之间具有相应的中间柄部40c和42c。可以颠倒换用的螺丝刀尖头件40和42是这样形成的，即：柄部40c和42c基本上为六角形且其长度当完全***时能从插管38中凸出。由于这些特点，插管38适合于***该插接件16的轴向延伸孔26中，而将可颠倒换用的螺丝刀尖头件如40和42的柄部如40c和42c的凸出部安置在插接件16之孔26的基本上呈六角形的部分34中。
现在参照图2和3，插接件16的外表面20形成有多个与手柄配合的基本上沿轴向延伸的细花键槽52，后者与手柄14配合构成该运动传递部件的至少另一部分。外部弹簧膨胀室24沿外表面20设置在基本上位于插接件16两端28和30的中间但更靠近具有轴向延伸孔26的端部28的某点处，该室具有面向外部的平滑圆筒形表面54。采用此种结构，可膨胀/可压缩的弹簧机构18包括一个制动件，该制动件包括一个安置在穿过圆筒形表面54的孔58中的球56和一个围绕圆筒形表面54安置的带60，后者将球56限制在孔58中。
在端部30处通过插接件或套管16将转动从手柄14传递给紧固件配合部件12，而可膨胀/可压缩的弹簧机构18的位置远离端部30，通过这样设置弹簧机构18，该可膨胀/可压缩的弹簧机构18产生夹紧作用的位置与使用工具10时将显著的力传递给紧固件配合部件12的位置相当远离。
现在参照图5-8，图中充分地例示沿顺时针和/或逆时针方向旋动紧固件的手动工具10′的另一实施例的特点。该实施例在许多方面与图1至4中所示的手动工具10相似，但其不同之处在于：插接件16′在一端28′处的轴向延伸孔26′基本上为六角形，而孔26′的基本六角形形状与手柄配合构成运动传递部件的至少一部分。如图1-4中例示的实施例一样，紧固件配合部件12′至少有一部分12c′基本上为六角形，以用于以啮合方式装入基本上呈六角形的孔26′中。
在图5-8中所示的实施例优选形式中，插接件16′中的轴向延伸孔26′在其整个长度上基本上为六角形。该紧固件配合部件12′可以有利地包括一个可以颠倒换用的螺丝刀尖头件，后者在其对置两端上具有第一和第二刀尖头12a′、12b′。采用这种结构，可以颠倒换用的螺丝刀尖头12′还具有一个位于第一和第二刀尖头12a′、12b′之间的柄部12c′，该柄部构成基本上呈六角形的上述部分。
采用本发明的任一实施例，得到的优点与先前已知的部件相比是明显的。该插接件或圆筒形套管是独有的，可以有利地使用包括具体图示的手动工具而同时具有其结构固有的许多显著优点的任何工具。对先前工具的特别重要的改进是本发明独有的固位和驱动特性。
更具体地说，应当很好地理解，安置在外部弹簧膨胀室中的制动件有许多显著优点。插接件或圆筒形套管的这一部分通常被限制在手柄14的一个孔内并在其中受到保护，在那里它不会受到由于细花键槽52与手柄孔的内表面之间相互作用而产生的转矩，插接件或圆筒形套管被压配在该手柄孔中，此外，不会有外部的接触或力施加到带上，那种力易于使带从其围绕并弹性夹住面向外部的光滑圆筒形表面54的位置上移开，在该位置上此带将球56固定在孔58中。可以理解，孔58的直径小于球56的直径，使得球56仅有一部分穿过孔58而凸现在轴向延伸孔26中。
可以理解，封闭端部30对插接件或圆筒形套管16的功能是重要的，因为它用于隔开刀尖头、如可以颠倒换用的螺丝刀尖头件40的刀尖头40a。更具体地说，封闭端部30用于隔开刀尖头、如***轴向延伸孔26中的可以颠倒换用的螺丝刀尖头件40的刀尖头40a，以避免尖头与手柄14接合，即：防止诸如40a的刀尖头被埋入手柄14的如木头或塑料的材料中，在那里尖头可能不能移出来。当然，图5和6中例示的实施例可能遇到同样问题，该实施例中在插接件或圆筒件套管中没有封闭端部。
还应指出，本发明例示为沿顺时针和/或逆时针方向旋动螺钉用的螺丝刀。可以理解，这仅仅例示了可以有利利用本发明优点的许多用途中的一个，因为本发明非常适合于通过做成下列形式的紧固件配合部件来旋动任何紧固件，例如做成螺母固定器、棘轮机构、固定紧固器拆除尖头等。虽然本发明作为螺丝刀可以有广泛的用途，但上述描述绝不能看作将其限定于该用途。
虽然上面提出了本发明的优选实施例，但可以理解，本领域的熟练人员可以改变本文中给出的细节而并不偏离所附权利要求中的真正精神和范围。
