Description
本發明係有關於一種棘輪扳手。 The invention relates to a ratchet wrench.
按,傳統進行鎖固用之扳手,於旋動緊固件時需要有較大之活動空間,且於扳動至一定程度後,使用者需要抽離緊固件再重新調整角度插接,以進行下一次扳動,如此的操作方式不甚便利且耗時。因此,有業者開發出往復式棘輪頭,以便於讓使用者能夠於小範圍內來回扳動扳手而無須重新插接,且可切換於正轉空轉或逆轉空轉等模式之切換結構,如台灣專利I690394、M590508即屬此類。 Press, the traditional wrench used for locking requires a large space for movement when turning the fastener. After the wrench is turned to a certain extent, the user needs to pull out the fastener and readjust the angle for the next step. This operation is inconvenient and time-consuming. Therefore, some manufacturers have developed a reciprocating ratchet head so that the user can turn the wrench back and forth in a small range without re-inserting it, and can switch between forward idling or reverse idling modes, such as the Taiwan patent. I690394 and M590508 fall into this category.
然而,此類習知棘輪扳手之切換結構皆設置於棘輪頭,因此切換結構離扳手之握把較遠,使用者欲進行切換時即必須用另一手才能順利控制切換結構,如此使用方法即為不便,會大幅影響作業效率,存在即待改善之缺弊。 However, the switching structure of this type of conventional ratchet wrench is arranged on the ratchet head, so the switching structure is far away from the handle of the wrench. When the user wants to switch, he must use his other hand to smoothly control the switching structure. This is how to use it. Inconvenience will greatly affect work efficiency, and there are shortcomings that need to be improved.
因此,有必要提供一種新穎且具有進步性之棘輪扳手,以解決上述之問題。 Therefore, it is necessary to provide a novel and progressive ratchet wrench to solve the above problems.
本發明之主要目的在於提供一種棘輪扳手,使用者可僅使用握持於扳手握把之單手進行切換,以提高作業效率。 The main purpose of the present invention is to provide a ratchet wrench that the user can switch using only one hand held on the wrench handle to improve working efficiency.
為達成上述目的,本發明提供一種棘輪扳手,包括一本體、一驅動件、一棘齒組件及一切換組件。該本體包括相連接之一柄部及一頭部,該柄部沿一第一方向延伸,該頭部沿橫向該第一方向之一第二方向開設有一容室。該驅動件圍繞該第二方向轉動地設於該容室內,並設有一環齒部。該棘齒組件包括二棘齒件,該二棘齒件分別可擺動地設於該容室內並具有朝該環齒部卡抵之趨勢。該切換組件包括一轉動軸及一抵頂件,該轉動軸圍繞該第一方向轉動地設於該柄部內,該抵頂件同動連接於該轉動軸並位於該容室內,藉由該轉動軸轉動以帶動該抵頂件,該抵頂件選擇性地抵頂於該二棘齒件其中一者以脫離該環齒部。 In order to achieve the above object, the present invention provides a ratchet wrench, which includes a body, a driving member, a ratchet assembly and a switching assembly. The body includes a connected handle and a head. The handle extends along a first direction, and the head has a holding chamber along a second direction transverse to the first direction. The driving member is disposed in the container to rotate around the second direction and is provided with a ring tooth portion. The ratchet assembly includes two ratchet parts. The two ratchet parts are respectively swingably disposed in the container and have a tendency to engage with the ring tooth portion. The switching component includes a rotating shaft and a push piece. The rotation shaft is installed in the handle to rotate around the first direction. The push piece is synchronously connected to the rotation shaft and is located in the container. By the rotation The shaft rotates to drive the resisting component, and the resisting component selectively resists one of the two ratchet components to disengage from the ring tooth portion.

該切換組件4包括一轉動軸41及一抵頂件42,該轉動軸41圍繞該第一方向13轉動地設於該柄部11內,該抵頂件42同動連接於該轉動軸41並位於該容室15內,藉由該轉動軸41轉動以帶動該抵頂件42,該抵頂件42選擇性地抵頂於該二棘齒件31其中一者以脫離該環齒部21。
The
藉此,由於該轉動軸41係圍繞該第一方向13轉動地設於該柄部11內,使用者藉由控制該轉動軸41轉動即可帶動該抵頂件42轉動,該抵頂件42即可
選擇性地抵頂於該二棘齒件31其中一者,以控制該驅動件2進行順時針空轉或逆時針空轉,以達到棘輪效果。
Therefore, since the rotating
於本實施例中該棘輪扳手另包括一控制件5,該控制件5與該轉動軸41相連接,該柄部11另設有一弧形槽18,該弧形槽18沿該柄部11之周向延伸,該控制件5滑設於該弧形槽18並與該轉動軸41相連接,因此當使用者單手握持於該握把時僅需使用拇指撥動該控制件5,即可帶動該該轉動軸41轉動,即可進行切換,使用上較方便。
In this embodiment, the ratchet wrench further includes a
具體而言,該控制件5包括一撥動件51與一定位件52,該撥動件51為弧形並貼抵於該柄部11,該定位件52可滑動地插設於該弧形槽18並連接於該撥動件51與該轉動軸41之間,以使該撥動件51順利地沿該柄部11之周向滑動且不會脫離該柄部11,於本實施例中該定位件52螺接於該轉動軸41。
Specifically, the
其中,該容室15之內壁設有二凹部16,該二棘齒件31分別設有一凸軸311,該二凸軸311分別樞設於該二凹部16,以使該二棘齒件31可順利地相對於該容室15中擺動而不會滑動。
Among them, the inner wall of the
較佳地,該柄部11與該容室15之間連通設有一通孔111,該轉動軸41之一端經由該通孔111伸入該容室15,該通孔111位於該二凹部16之間,各該棘齒件31遠離該環齒部21之一端分別設有一凹槽312、另一端設有一棘齒部313,各該棘齒部313與該環齒部21相卡抵,該轉動軸41穿過該二凹槽312,該二凹槽312可避免該二棘齒件31與該轉動軸41相干涉,且可有效地減少該容室15之體積。
Preferably, a through
另外,該抵頂件42包括一連接部421及一抵頂部422,該抵頂部422橫向連接於該連接部421,該連接部421組接於該轉動軸41伸入該容室15之一端。進一步的說,該抵頂部422沿一側延伸,另一側與該連接部421形成一削平面423,
該轉動軸41之一端設有一凹階面411,該削平面423貼抵於該凹階面411並相鎖固,以使該連接部421與該抵頂部422相固定,於本實施例中該連接部421與該凹階面411藉由一鎖固件43相鎖固,以較穩固,如此藉由該抵頂件42分別大量製造出該連接部421與該抵頂部422後再進行組裝的特性可有效降低該抵頂件42之製造成本。
In addition, the resisting
值得一提的是,該抵頂部422之相對兩側分別設有一凸部424,該二凸部424凸出於該削平面423,藉由該轉動軸41轉動以帶動該抵頂件42,該抵頂件42之該二凸部424分別可選擇性地抵頂於該二棘齒件31其中一者脫離該環齒部21,因此該轉動軸41無須具有大幅度的轉動(可小於180度)角度即可使該二凸部424可選擇性地抵頂於該二棘齒件31,於操作上較方便。
It is worth mentioning that the opposite sides of the top 422 are respectively provided with a
