Description
本發明是關於一種手工器具,特別是關於一種用於鎖固及拆卸螺件的棘輪扳手結構改良。 This invention relates to a hand tool, and more particularly to a structural improvement of a ratchet wrench for locking and removing a screw.
目前棘輪扳手是一種常見的手工器具之一,且棘輪扳手又可分為單向棘輪扳手與雙向棘輪扳手,其主要用於鎖固及拆除螺件。 At present, the ratchet wrench is one of the common hand tools, and the ratchet wrench can be divided into a one-way ratchet wrench and a two-way ratchet wrench, which are mainly used for locking and removing the screw.
依中華民國智財局之新型專利說明書公告號「M241173」,新型名稱「具高扭力值之棘輪扳手結構」,其揭露定義之元件,由圖式「第五圖」、「第六圖」,該驅動部(圖中標號31)側端並形成一容置槽(圖中標號32),且該容置槽(圖中標號32)係供容置一摯動塊(圖中標號50)及彈性件(圖中標號34),其中該容置槽(圖中標號32)一端具有內螺紋段,能以利用一具外螺紋段之鎖固件(未標號)固定,且避免內部的摯動塊(圖中標號50)與彈性件(圖中標號34)掉出該容置槽(圖中標號32),在安裝順序上,必須先將摯動塊(圖中標號50)裝入該容置槽(圖中標號32)再依序裝設彈性件(圖中標號34)後,再由位於該容置槽(圖中標號32)外段的內螺紋(未標號)螺組一鎖固件(圖中未示)來限位摯動塊(圖中標號50)彈性件(圖中標號34)。 According to the new patent specification bulletin No. "M241173" of the Republic of China Intellectual Property Office, the new name "ratchet wrench structure with high torque value", which reveals the components of the definition, is shown in the figure "fifth figure" and "sixth figure". The accommodating portion (reference numeral 32 in the figure) is formed at a side end of the driving portion (reference numeral 31 in the figure), and the accommodating groove (reference numeral 32 in the figure) is for accommodating a swaying block (reference numeral 50 in the figure) and An elastic member (reference numeral 34 in the figure), wherein the receiving groove (reference numeral 32 in the figure) has an internal thread segment at one end, which can be fixed by a fastener (not numbered) of an externally threaded segment, and avoids internal turbulent blocks (the reference numeral 50 in the figure) and the elastic member (reference numeral 34 in the figure) fall out of the accommodating groove (reference numeral 32 in the figure), and in the installation sequence, the tampering block (reference numeral 50 in the figure) must first be loaded into the accommodating The slot (reference numeral 32 in the figure) is then sequentially mounted with an elastic member (reference numeral 34 in the figure), and then an internal thread (not labeled) located in the outer portion of the receiving groove (reference numeral 32 in the figure) is a set of lock fasteners ( The figure is not shown) to limit the elastic block (reference numeral 50 in the figure) to the elastic member (reference numeral 34 in the figure).
然而,上揭習知專利結構中,該容置槽(圖中標號32)外段的內螺紋(未標號)很容易在螺組該鎖固件(未標號)過程中,因為施力不當及頻繁拆裝下的磨損而無法有效結合鎖固件(未標號)而造成鬆退,進而影響扳手 的操作使用功能,是為習知專利使用上的缺點之一。 However, in the above-mentioned patented structure, the internal thread (not labeled) of the outer section of the receiving groove (reference numeral 32 in the figure) is easily in the process of screwing the fastener (not labeled) because of improper application and frequent Wear under disassembly and assembly can not effectively combine the lock (not labeled) and cause the loosening, which affects the wrench The operational use function is one of the disadvantages of the use of the conventional patent.
再者,在前述鎖固件(未標號)鬆退情形下,甚至會因為鎖固件(未標號)可能鬆脫掉落,造成摯動塊(圖中標號50)與彈性件(圖中標號34)也陸續掉出而瓦解,而使扳手喪失使用功能,是為習知專利使用上的缺點之二。 Moreover, in the case that the aforementioned fastener (not labeled) is loosened, even the lock (unlabeled) may be loosened and dropped, causing the swaying block (reference numeral 50 in the figure) and the elastic member (reference numeral 34 in the figure). It also fell out and collapsed, and the use of the wrench to lose the function is the second disadvantage of the use of the patent.
所以,如何針對上述習知前案結構該容置槽外段的內螺紋因為施力不當及頻繁拆裝下的磨損,而無法結合鎖固件與造成鬆退,以及因為鎖固件鬆脫掉落造成摯動塊與彈性件陸續掉出而瓦解而喪失使用功能等缺點而進行創新發明者,是為本案所欲行解決的困難點所在。 Therefore, how to solve the above-mentioned conventional structure of the outer thread of the accommodating groove is not able to combine the lock and the looseness due to improper application and wear under frequent disassembly, and because the lock is loosely dropped The inventors who invented the inventors and the elastic parts to fall out and collapse, and lose the use of functions, etc., are the difficult points to be solved in this case.
