Description

替換式工具Replacement tool

本發明是有關於一種替換式工具。 The present invention relates to a replacement tool.

在許多作業中，常需透過輔助工具來進行，例如敲擊、鎖固、拆卸、延伸工具長度等手工具。 In many operations, it is often necessary to use auxiliary tools, such as hand tools such as knocking, locking, disassembling, and extending the length of the tool.

而一般習知手工具之本體與工作頭多為一固定為一體，雖然結構強度較佳，但不適用於多種不同規格、作業之需求，因此常需要備有多個相對應尺寸之手工具，成本較高，重量中且較佔空間。 In general, the body and the working head of the conventional hand tools are mostly fixed as a whole. Although the structural strength is better, it is not suitable for a variety of different specifications and operations. Therefore, it is often necessary to prepare hand tools of corresponding sizes. The cost is high, the weight is medium and it takes up more space.

習知另有透過螺栓及螺帽組接手工具之本體與工作頭者，藉此達到拆換功能，然而，每次拆換時皆需拆除再鎖固螺栓及螺帽，耗時費力，極為不便。 It is known that the main body and the working head of the tool are connected to the tool through a set of bolts and nuts, so as to achieve the function of disassembly and replacement. However, it is necessary to remove and re-lock the bolts and nuts every time when disassembling and replacing, which is time-consuming, laborious, and extremely inconvenient. .

因此，有必要提供一種新穎且具有進步性之替換式工具，以解決上述之問題。 Therefore, it is necessary to provide a novel and progressive alternative tool to solve the above problems.

本發明之主要目的在於提供一種替換式工具，可快速且方便地拆換。 The main purpose of the present invention is to provide a replaceable tool that can be quickly and easily replaced.

為達成上述目的，本發明提供一種替換式工具，包括：一本體，具有一接孔，該接孔沿一第一軸線延伸；及一控制件，插設於該本體且包括一卡掣凸部，可延一橫向於該第一軸線之一第二軸線移動於一鎖定位置及一釋放位置之間；其中，當該控制件位於該鎖定位置時，該卡掣凸部徑向凸入該接孔；當該控制件由該鎖定位置朝該釋放位置移動時，該卡掣凸部遠離該第一軸線。 In order to achieve the above object, the present invention provides a replacement tool, comprising: a main body with a connecting hole extending along a first axis; and a control member inserted into the main body and including a locking protrusion , which can be moved between a locking position and a releasing position along a second axis transverse to the first axis; wherein, when the control member is in the locking position, the locking protrusion radially protrudes into the connection a hole; when the control member moves from the locking position to the releasing position, the locking protrusion is away from the first axis.
