Description
本創作主要係揭示一種開口扳手，尤指具有棘動功能的開口扳手。This creation mainly discloses an open-end wrench, especially an open-end wrench with a ratcheting function.
請參照美國專利號第2700315號之「OPEN-END RATCHET WRENCH」專利案，其為一種開放式棘輪扳手，在棘輪扳手的一端具有扳手頭(wrench head)，扳手頭中形成一個槽(slot 11)，槽的兩側分別設有一個棘齒塊(dog 17)，棘齒塊透過一個銷(pin 18)樞設於凹座(recess 16)中，使棘齒塊能夠相對扳手頭樞轉，並且棘齒塊的一側透過銷(pin 20)樞設有一個彈簧(spring 19)，使棘齒塊在相對扳手頭樞轉的過程中，在自然狀態下會回復到原始位置。Please refer to the "OPEN-END RATCHET WRENCH" patent of U.S. Patent No. 2,700,315, which is an open type ratchet wrench having a wrench head at one end of a ratchet wrench and a slot in the wrench head (slot 11) a ratchet block (dog 17) is respectively disposed on both sides of the slot, and the ratchet block is pivotally disposed in the recess 16 through a pin (pin 18), so that the ratchet block can pivot relative to the wrench head, and One side of the ratchet block is pivotally provided with a spring (spring 19) through the pin (pin 20), so that the ratchet block returns to the original position in a natural state during pivoting relative to the wrench head.
然而，棘齒塊透過銷件樞設於棘輪扳手的設計，致使棘輪扳手在製造時必須付出多餘的製造及組裝成本，棘輪扳手在使用時，扭轉待驅動件時所需的扭力是由銷件承受，銷件在扳手頭與棘齒塊之間的截面承受使用者扭轉待驅動件所施予扭力而造成的剪力時，因承受面積小，容易造成銷件因受力過大而破壞，同時彈簧亦是透過銷而設於棘輪扳手中，亦有徒增製造及組裝成本的問題。However, the ratchet block is pivotally disposed on the ratchet wrench through the pin member, so that the ratchet wrench must be subjected to unnecessary manufacturing and assembly costs. When the ratchet wrench is used, the torque required to twist the member to be driven is the pin member. When the cross section between the wrench head and the ratchet block is subjected to the shearing force caused by the user to twist the torque applied by the driving member, the bearing area is small, and the pin member is easily damaged due to excessive force. Springs are also placed in the ratchet wrench through the pins, which also increases the cost of manufacturing and assembly.
並且，棘輪扳手用以容納棘齒塊的凹座的形狀設計不易加工，必須耗費多餘的時間及加工成本才能完成加工，造成不必要的資源浪費。Moreover, the shape of the recess of the ratchet wrench for accommodating the ratchet block is not easy to process, and it takes extra time and processing cost to complete the processing, resulting in unnecessary waste of resources.
再者，棘輪扳手在使用時若因棘齒塊角度不正確，以尖角位置接觸待驅動件而欲直接驅動待驅動件時，會因接觸面積過小，造成棘輪扳手棘齒塊或待驅動件其中之一損壞變形。Furthermore, if the ratchet wrench is in use due to an incorrect angle of the ratchet block and contacts the to-be-driven member at a sharp angular position and directly drives the member to be driven, the ratchet wrench ratchet block or the member to be driven may be caused by the contact area being too small. One of them is damaged.

本創作開放式棘動扳手其主要目的在於，提供一種棘動件樞設於貫穿式樞轉槽的設計，棘動件直接樞設於開口扳手本體能夠有效降低開口扳手的製造及組裝成本，並且開口扳手在作動時，使用者扭轉待驅動件所施予扭力全部皆由棘動件與扳手本體之間的接觸面分擔，有效增強開口扳手的結構強度，增加開口扳手的使用壽命，同時，貫穿式樞轉槽的設計加工容易，能夠有效降低開口扳手本體的製造成本。The main purpose of the open-type ratcheting wrench is to provide a design in which the ratchet member is pivotally disposed in the penetrating pivoting groove, and the pivoting member directly pivoted on the open-end wrench body can effectively reduce the manufacturing and assembly cost of the open-end wrench, and When the open-end wrench is actuated, the torque applied by the user to twist the driven member is all shared by the contact surface between the ratchet member and the wrench body, thereby effectively enhancing the structural strength of the open-end wrench and increasing the service life of the open-end wrench. The design and processing of the pivoting groove is easy, and the manufacturing cost of the open-end wrench body can be effectively reduced.
本創作開放式棘動扳手其次要目的在於，提供一種棘動件的棘動頭呈圓形柱狀的設計，無論棘動件以任何角度接觸待驅動件，棘動件皆能夠平均分攤受力，維持棘動件的結構強度，增加開口扳手的使用壽命。The second purpose of the present invention is to provide a ratcheting member with a rounded column shape. The ratchet member can evenly share the force regardless of the angle at which the ratchet member contacts the member to be driven at any angle. Maintain the structural strength of the ratchet and increase the service life of the open end wrench.
