Description

掌心型棘輪扳手之輔助裝置Auxiliary device for palm type ratchet wrench

本發明係關於一種掌心型棘輪扳手，特別係關於一種掌心型棘輪扳手之輔助裝置。The present invention relates to a palm-type ratchet wrench, and in particular to an auxiliary device for a palm-type ratchet wrench.

掌心型棘輪扳手於技術領域中亦稱為掌心雷，其包含一棘輪在內，其特點在於體積小，方便攜帶、使用，使用者在使用掌心型棘輪扳手時僅須用手握持，即可驅動掌心型棘輪扳手旋轉，以鎖固或鬆釋螺栓或螺帽。The palm-type ratchet wrench is also called a palm ratchet in the technical field. It contains a ratchet and is characterized by its small size, easy to carry and use. When using the palm-type ratchet wrench, the user only needs to hold it with his hand. Drive the palm-type ratchet wrench to rotate to lock or loosen bolts or nuts.

掌心型棘輪扳手雖具有上述優點，然而，由於並不具有任何手把等延伸之結構，故不具備足夠長的力臂，是以，在驅動螺栓或螺帽時使用者便需要施予較大的力量，因此，如果遭遇鎖固較緊的螺帽或螺栓，則可能面臨無法鬆釋的情況，為此，需要一種方便攜帶、使用，且可靈活地與掌心型棘輪扳手配合之輔助裝置。Although the palm-type ratchet wrench has the above advantages, however, since it does not have any extended structure such as a handle, it does not have a long enough force arm. Therefore, the user needs to exert a larger force when driving the bolt or nut. Therefore, if you encounter a tightly locked nut or bolt, you may be unable to loosen it. For this reason, you need an auxiliary device that is easy to carry and use and can flexibly cooperate with a palm-type ratchet wrench.

本發明提供一種掌心型棘輪扳手之輔助裝置，其主要目的在於提供一種方便使用，且可靈活地與掌心型棘輪扳手配合之輔助裝置。The present invention provides an auxiliary device for a palm-type ratchet wrench. Its main purpose is to provide an auxiliary device that is easy to use and can flexibly cooperate with the palm-type ratchet wrench.

為達成前述目的，本發明掌心型棘輪扳手之輔助裝置，包括：In order to achieve the aforementioned objects, the auxiliary device of the palm-type ratchet wrench of the present invention includes:
