Description

  The present invention relates to a hexagonal wrench used for tightening and removing a hexagonal socket bolt, and in particular, facilitates tightening and removal of a hexagonal socket bolt driven by a ratchet wrench and screwed into a very narrow gap. In addition, the present invention relates to a hexagonal wrench ratchet adapter in which power loss is suppressed by a structure in which component parts are integrated by integral molding, and component management at the time of storage is easy.

  The hex socket bolt is tightened and removed using an L-shaped hexagonal wrench with a bent part, but insert the tip of the hexagonal wrench into the hexagonal hole of the bolt and rotate, and remove each time It takes time and labor and is very complicated because it requires repetitive manual work such as reinsertion and rotation. In particular, when tightening and removing a hexagonal socket bolt screwed into a very narrow gap, the height of the L-shaped hexagonal wrench is large and it may not be possible to work with obstacles around it. Also, in some cases, the tip of the hexagonal wrench could not be properly engaged in the hexagonal hole of the bolt, resulting in vague tightening.

  In order to solve the above-mentioned problems, conventionally, proposals have been made to enable easy tightening and removal of bolt and nut using a ratchet wrench. For example, a "ratchet wrench adapter" (Patent Document 1) has been proposed which can perform the same work as the handle of a socket wrench by attaching the ratchet wrench as an adapter. Specifically, in order from the top, place a wing nut, flat washer, full screw bolt, regular hexagonal column, thin circular plate, regular square pole on top and bottom extending center line, and one is a wing nut and flat washer. In the proposal of the adapter of the ratchet wrench which put together the center lines of the respective center lines and make them one piece, and put the center lines of the whole screw bolt, regular hexagonal column, thin disc and regular square pole together. is there.

  However, the proposal of the “ratchet wrench adapter” is limited to the purpose of fastening the bolt and nut by the use of the interchangeable box wrench, and the hexagonal socket bolt screwed into the extremely narrow gap portion It was not intended to tighten or remove the

  In addition, it is used for screwing in and loosening screws and the like in a very narrow working space, and "Ratchet driver" (patent document 2) that can also be used for tightening bolts and nuts etc. is proposed. It is done. Specifically, a holder socket having a bit detachably mounted is detachably mounted on a wrench having a ratchet mechanism provided at at least one end of the lever, and the holder socket can be rotated forward and reverse by the ratchet mechanism. In addition, on the lower side of the lever, it is a proposal of a ratchet driver having a knob for quick rotation attached to the side of the holder socket.

  However, the proposal of such a "ratchet driver" is limited to the purpose of using the application for fastening a screw by a holder socket (a function that can also be used for fastening bolts, nuts, etc. simply utilizes a ratchet wrench) The part management and assembly work occur because the parts configuration is more than one, so the purpose is to tighten and remove the hex socket bolt screwed into the very narrow gap. In addition, there is a problem that parts management at the time of storage becomes complicated.

  Furthermore, "hexagon wrench-less adapter" (Patent Document 3) has been proposed, which makes it possible to work with a spanner without using a hexagonal wrench and has various hexagonal wrench functions with one type of spanner. Specifically, it has been proposed that a wrench and flanges and a spanner hook are provided in the wrench to fit in a small space.

  However, in the configuration of such a “hexagon wrench-less adapter” proposal, the flange portion has substantially the same diameter as the spanner hook portion, and therefore the adapter can not be rotated by a screwdriver via the flange portion. Also, since the tip of the wrench portion is not chamfered in a tapered manner, it is assumed that the tip of the wrench portion may not be properly engaged with the hexagonal hole of the hexagonal socket bolt screwed into the extremely narrow gap portion. As a result, there is a problem that it becomes vague tightening.

  The applicant has focused on the bolt nut and screw tightening / removing means using a ratchet wrench, and can simply and reliably work on the tightening / removing of the hexagonal socket bolt screwed into the very narrow gap. It is easy to fasten and remove hexagonal socket bolts in extremely narrow gaps under the idea of impossible heels, and at the time of storage, control of power loss (power loss) by the structure where components are integrated by integral molding In the present invention, a ratchet adapter is easily developed, and leads to the proposal of the “hexagon wrench ratchet adapter” according to the present invention.
