以下僅以實施例說明本發明可能之實施態樣，然並非用以限制本發明所欲保護之範疇，合先敘明。 The following examples are only used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, and are described together first.

請參考圖1至圖6，其顯示本發明之一實施例，本發明之套筒扳手包括：一套接部1、一連接臂2、一操作桿3及一插銷4。 Please refer to FIG. 1 to FIG. 6 , which show an embodiment of the present invention. The socket wrench of the present invention includes: a socket 1 , a connecting arm 2 , an operating rod 3 and a plug 4 .

該套接部1沿一第一方向6貫設有一套接孔13，該套接孔13係為多角邊形用以套接於螺絲、螺帽、螺栓等緊固件。該連接臂2橫向該第一方向6地一體延伸於該套接部1，以期有較佳之結構強度。該插銷4為單一構件，該插銷4非垂直該第一方向6地穿設連接該連接臂2與該操作桿3，進而該操作桿3可以該插銷4為軸地相對該套接部1擺動。 The socket portion 1 is provided with a socket hole 13 along a first direction 6 , and the socket hole 13 is polygonal in shape for socketing with fasteners such as screws, nuts and bolts. The connecting arm 2 integrally extends to the socket portion 1 transversely to the first direction 6, so as to have better structural strength. The plug 4 is a single component, the plug 4 is not perpendicular to the first direction 6 and passes through and connects the connecting arm 2 and the operating rod 3 , and the operating rod 3 can swing relative to the socket portion 1 with the plug 4 as the axis .

於本實施例中，如圖3所示，該插銷4係沿平行該第一方向6地串接該連接臂2與該操作桿3，即該插銷4之延伸方向等同於該套接孔13之開口方向，故當該套接部1套接於緊固件沿轉動方向進行旋動時，該操作桿3之作用力係沿該插銷4之徑向作用於該插銷4上，進而該插銷4有足夠之接觸面積承受來自該操作桿3之作用力，且可均勻地將作用力再分散傳遞予該連接臂2，使得該插銷4較能夠維持結構之完整性不易有應力集中毀損之情況發生。 In this embodiment, as shown in FIG. 3 , the plug 4 is connected in series with the connecting arm 2 and the operating rod 3 parallel to the first direction 6 , that is, the extension direction of the plug 4 is equal to the socket hole 13 . Therefore, when the socket 1 is socketed on the fastener and rotates in the rotating direction, the force of the operating rod 3 acts on the plug 4 along the radial direction of the plug 4, and the plug 4 There is enough contact area to withstand the force from the operating rod 3, and the force can be uniformly redistributed and transmitted to the connecting arm 2, so that the plug 4 can maintain the structural integrity and is less prone to stress concentration damage. .

較具體地說，該連接臂2包含有二樞耳21，二該樞耳21呈間隔配置而定義出一插接空間22，該操作桿3之部分伸入該插接空間22，二該樞耳21分別貫設有一穿孔23及一螺孔24，該插銷4係穿設過該穿孔23及該操作桿3地螺接於該螺孔24，故在操作時，該插銷4可將來自該操作桿3之作用力分散傳遞至該二樞耳21，達到均勻對稱地驅使該套接部1之目的與確保該插銷4之結構完整。 More specifically, the connecting arm 2 includes two pivot ears 21 , the two pivot ears 21 are spaced apart to define an insertion space 22 , a portion of the operating rod 3 extends into the insertion space 22 , and the two pivot ears 21 are spaced apart to define an insertion space 22 . The ears 21 are respectively provided with a through hole 23 and a screw hole 24. The plug 4 is passed through the through hole 23 and the operating rod 3 and is screwed to the screw hole 24. Therefore, during operation, the plug 4 can pass through the through hole 23 and the operating rod 3 to the screw hole 24. The force of the operating lever 3 is distributed and transmitted to the two pivot ears 21 to achieve the purpose of driving the socket portion 1 evenly and symmetrically and to ensure the structural integrity of the latch 4 .

更具體地說，該連接臂2另包含有一本體25，該本體25連接於該二樞耳21與該套接部1之間，該操作桿3另包含有相連接之一頭部31及一身部32，該頭部31伸入該插接空間22，該身部32位於該插接空間22外且徑向尺寸大於該二樞耳21之垂直距離；其中，如圖4所示，該頭部31呈板狀，該身部32呈圓柱形，當該操作桿3相對該套接部1擺動至極限位置進行旋動時，該身部32係壓抵於該本體25及該二樞耳21其中至少一者，藉此使用者施力予該操作桿3所產生的作用力可經由二路徑傳遞至該連接臂2，路徑一為透過該身部32直接作用於該本體25，路徑二為透過該頭部31、該插銷4作用於該二樞耳21，如此一來，可以有效降低該插銷4的總受力，故當該操作桿3受到較大驅動力作用時，該插銷4依然能夠保有完整結構。 More specifically, the connecting arm 2 further includes a main body 25 , the main body 25 is connected between the two pivot ears 21 and the socket portion 1 , and the operating rod 3 further includes a head portion 31 and a body connected to each other. part 32, the head part 31 extends into the insertion space 22, the body part 32 is located outside the insertion space 22 and the radial dimension is greater than the vertical distance between the two pivot ears 21; wherein, as shown in FIG. The body 31 is plate-shaped, and the body 32 is cylindrical. When the operating rod 3 rotates relative to the socket portion 1 to the limit position, the body 32 is pressed against the main body 25 and the two pivot ears At least one of 21, whereby the force generated by the user applying force to the operating rod 3 can be transmitted to the connecting arm 2 through two paths, the first path is to directly act on the body 25 through the body 32, and the second path is to pass through the body 25. The head 31 and the plug 4 act on the two pivot ears 21, so that the total force of the plug 4 can be effectively reduced, so when the operating lever 3 is acted by a large driving force, the plug 4 can still be Keep the complete structure.

值得一提的是，該插銷4包含有相對之一驅動部41及一螺接部42，該穿孔23位於該驅動部41與該螺孔24之間，該螺接部42穿設過該穿孔23地螺接於該螺孔24，該驅動部41之部分嵌入該穿孔23，其中，於該驅動部41之端面及該螺接部42之端面其中至少一者設有一組接部以驅使該插銷4旋動。 It is worth mentioning that the plug 4 includes a driving part 41 and a screwing part 42 opposite to each other, the through hole 23 is located between the driving part 41 and the screw hole 24 , and the screwing part 42 passes through the through hole 23 is screwed to the screw hole 24, a part of the driving part 41 is inserted into the through hole 23, wherein at least one of the end surface of the driving part 41 and the end surface of the screwing part 42 is provided with a set of connecting parts to drive the The latch 4 is turned.

於該驅動部41設有一第一組接部51，於該螺接部42設有一第二組接部52，該第一組接部51及該第二組接部52供分別連接工具以受其驅使旋動，換言之，透過該第一組接部51可以將完整地該插銷4旋入或旋出該二樞耳21，而當該插銷4發生斷裂之情況時，可以透過工具將該第一組接部51與該第二組接部52分別自該二樞耳21取出。 The driving portion 41 is provided with a first assembling portion 51, and the screwing portion 42 is provided with a second assembling portion 52. The first assembling portion 51 and the second assembling portion 52 are respectively used for connecting tools to receive It drives the rotation, in other words, through the first assembling portion 51, the bolt 4 can be completely screwed into or out of the two pivot ears 21, and when the bolt 4 is broken, the second bolt 4 can be screwed through a tool. The first assembly portion 51 and the second assembly portion 52 are respectively taken out from the two pivot ears 21 .

較進一步地說，該驅動部41之徑向尺寸大於該螺接部42之徑向尺寸，故該第一組接部51之型態較佳異於該第二組接部52之型態，以便可配合該驅動部41與該螺接部42之結構強度不同來相對應變化。更進一步地說，該第一組接部51及該第二組接部52分別係為凹槽，且該第一組接部51之截面積大於該第二組接部52之截面積，以期該螺接部42可以保有較多完整連續結構地進行螺接。於本實施例中，該第一組接部51係為六角凹槽，該第二組接部52係為直線凹槽，以可配合日常生活中常見的六角扳手與一字起子使用。 More specifically, the radial dimension of the driving portion 41 is larger than the radial dimension of the screwing portion 42 , so the shape of the first assembling portion 51 is preferably different from that of the second assembling portion 52 . In order to adapt to the different structural strengths of the driving portion 41 and the screwing portion 42, corresponding changes can be made. Furthermore, the first set of The part 51 and the second assembling part 52 are respectively grooves, and the cross-sectional area of the first assembling part 51 is larger than that of the second assembling part 52, so that the screwing part 42 can keep more integrity Bolted in a continuous structure. In this embodiment, the first assembling portion 51 is a hexagonal groove, and the second assembling portion 52 is a straight groove, which can be used with a hexagonal wrench and a flat-blade screwdriver commonly used in daily life.

該套接部1之一第一側部11與該驅動部41係位於該操作桿3之同一側，較佳地，於該第一方向6上，該第一側部11係凸出於該連接臂2且高於該驅動部41，於障礙物多的環境中，該第一側部11於伸入過程中可確保該驅動部41不會受到撞擊，確保該插銷4之結構穩定性及完整性。並且，較高的該第一側部11可以增加該套接部1於該第一方向6之長度，進而可適用於更多種長度的緊固件。 A first side portion 11 of the socket portion 1 and the driving portion 41 are located on the same side of the operating rod 3 . Preferably, in the first direction 6 , the first side portion 11 protrudes from the operating rod 3 . The connecting arm 2 is higher than the driving part 41 . In an environment with many obstacles, the first side part 11 can ensure that the driving part 41 will not be impacted during the process of extending, ensuring the structural stability of the latch 4 and completeness. In addition, the taller first side portion 11 can increase the length of the socket portion 1 in the first direction 6, thereby being applicable to fasteners with more lengths.

該套接部1另包含有一第二側部12，該第二側部12位於該第一側部11之相反側，該第二側部12與該螺接部42位於該操作桿3之同一側，該第二側部12與該連接臂2齊平，該螺接部42之端面未凸出該連接臂2以有效防止非預期碰撞。 The socket portion 1 further includes a second side portion 12 , the second side portion 12 is located on the opposite side of the first side portion 11 , and the second side portion 12 and the screwing portion 42 are located on the same side of the operating rod 3 . The second side portion 12 is flush with the connecting arm 2 , and the end surface of the screwing portion 42 does not protrude from the connecting arm 2 to effectively prevent unexpected collisions.
