Description
本發明與鋸柄結構有關，特別是指一種鋸柄改良之結構。 The present invention relates to a saw handle structure, and particularly to an improved structure of a saw handle.
如第9圖所示，為習知的鋸柄9之構造，其具有一握部91以及一與握部91呈間隔設置之護弓92，並於鋸柄9上樞設有一與護弓92位於同側之擺臂93，且護弓92具有一可供擺臂93側向擺入之容室921，而於擺臂93上設置有至少一可供一鋸片接設之擋桿94，鋸柄9上具有一與護弓92位於同側之插槽，另於鋸柄9上樞設有一控制件96和一扣件97，且控制件96有一扳動部961在鋸柄9的底部露出，擺臂93具有一對應扣件97而設之勾部931；而欲將鋸片組裝至鋸柄9上時，先將鋸片與該擺臂93之擋桿94接設，再以手將擺臂93樞擺至容室921內，並以扳動部961之扣件97勾著勾部931，接著再扳動扳動部961使其扣件97將勾部931扣住而定位擺臂93，即可完成鋸片組裝而可鋸切。 As shown in FIG. 9, the structure of the conventional saw handle 9 includes a grip portion 91 and a guard bow 92 disposed at a distance from the grip portion 91, and a bow guard 92 is provided on the saw handle 9. The swing arm 93 located on the same side, and the guard bow 92 has a receiving chamber 921 for swinging the swing arm 93 laterally, and at least one blocking rod 94 is provided on the swing arm 93 for a saw blade to be connected. The saw handle 9 has a slot on the same side as the guard bow 92, and a control member 96 and a fastener 97 are pivotally provided on the saw handle 9. The control member 96 has a trigger portion 961 at the bottom of the saw handle 9. As shown, the swing arm 93 has a hook portion 931 provided corresponding to the fastener 97; and when assembling the saw blade to the saw handle 9, firstly connect the saw blade with the blocking rod 94 of the swing arm 93, and then use the hand The swing arm 93 is pivoted into the receiving chamber 921, and the hook portion 931 is hooked by the fastener 97 of the trigger portion 961, and then the trigger portion 961 is moved to make the fastener 97 buckle the hook portion 931 to position the swing portion. The arm 93 can complete the saw blade assembly and can be cut.
然而，習知的鋸柄9於鋸片組裝時，須先將鋸片固定於擺臂93上，並將擺臂93之勾部931與扣件97勾扣，接著扳動扳動部961將擺臂93固定方能完成組裝，因此在鋸片組裝上因工序複雜且不順暢；此外，擺臂93與扳動部961皆僅以其一端與鋸柄9樞接，導致擺臂93與扳動部961若未以扣件97相互勾扣時，擺臂93與扳動部961之另一端容易懸 擺於鋸柄9外而缺乏保護，當受到外力撞擊時，容易導致擺臂93與扳動部961變形損傷，甚至是斷裂，進而使鋸柄9無法與鋸片組裝。 However, when the conventional saw handle 9 is assembled in the saw blade, the saw blade must be fixed on the swing arm 93, and the hook portion 931 of the swing arm 93 and the fastener 97 are hooked, and then the trigger portion 961 is moved to The swing arm 93 can only be assembled before it is fixed, so the assembly of the saw blade is complicated and not smooth. In addition, the swing arm 93 and the trigger portion 961 are only pivotally connected to the saw handle 9 with one end, resulting in the swing arm 93 and the trigger. If the moving part 961 is not hooked with each other by the fastener 97, the other end of the swing arm 93 and the pulling part 961 is easily suspended It is placed outside the saw handle 9 and lacks protection. When it is impacted by an external force, the swing arm 93 and the trigger portion 961 are easily deformed and damaged, or even broken, thereby preventing the saw handle 9 from being assembled with the saw blade.
有鑑於此，如何解決上述問題即為本發明所欲解決之首要課題。 In view of this, how to solve the above problems is the primary problem to be solved by the present invention.
