Description

Replacement wrench structure

The invention relates to an alternative wrench structure, in particular to a replacement wrench structure which is provided with a first body, a second body, a coupling member and a buckle, the coupling member being limited by the buckle, the buckle ring system The maximum stroke of the displacement of the coupling member is limited such that the coupling member is constrained from the buckle without being disengaged from the first body.

As previously known to us, the conventional replacement wrench structure, such as U.S. Patent No.: 7206102B1, and Taiwan Patent Application No.: I269689, patent name: plug-in tool structure (5), a plug-in tool The structure (5) is mainly composed of a tool body 1 and a triggering portion 2, wherein the handle portion 10 of the tool body 1 is provided with a connecting portion 11 at one end, and the connecting portion 11 is formed with a coupling groove 111. The accommodating portion 2 has a ferrule end 21 corresponding to the coupling groove 111, and the side of the ferrule end 21 is formed with at least one oblique abutting edge 213, and the slanting abutting edge 213 It is used to abut against the coupling groove 111 of the connecting portion 11, so that the pulling portion 2 and the connecting portion 11 can be adjusted to be combined in a laterally inclined state.

However, the missing structure of the conventional structure is that, as shown in the first figure of the U.S. Gazette, the pulling portion 2 can be freely inserted and replaced with the connecting portion 11, so that only the tool body 1 is needed. The plurality of different clamping portions 2 are assembled, and the tool body 1 can be shared in the patent structure, so that the cost of the tool body 1 can be saved, which is an advantage of the U.S. patent, but the buckle structure 211 of the pulling portion 2 is Composed of steel balls and springs, and each Each of the triggering portions 2 is required to be provided with a plurality of latching structures 211, that is, twenty latching portions 2, that is, twenty sets of latching structures 211, each of which needs to be provided with a snapping structure 211. That constitutes a considerable component cost.

In view of the lack of the above-mentioned alternative wrench structure, the inventors have been engaged in the manufacturing and design experience of related industries for many years, and finally have a product that can solve the drawbacks of the conventional replacement wrench structure.

Each of the clamping portions of the conventional device is provided with each buckle structure, and the plurality of buckle structures can be used for a considerable component cost. The present invention relates to a replacement wrench structure, and more particularly to a replacement wrench structure. The first body, the second body, the coupling member and the buckle are constrained by the buckle, and the buckle limits the maximum stroke of the displacement of the coupling member, so that the coupling member is limited to the buckle and is not The first body phase is disengaged, and the coupling member and the buckle ring system are only one.

The utility model relates to a replacement wrench structure, which comprises: a first system provided with a first coupling hole, a first ring groove and a socket groove; a second system is provided with a socket portion for receiving in the socket groove, The sleeve portion is provided with a second joint hole to be opposite to the first joint hole; a joint member is provided with a joint portion for screwing with the first joint hole, and the joint portion is provided with a second ring groove, The second ring groove is aligned with the first ring groove, the second ring groove is provided with a first side surface and a second side surface, and the bottom end of the joint portion is provided with one end portion, and the end portion is sleeved in the second portion a coupling portion is disposed on the coupling member, and the rotating portion is protruded from the first body; the two ends of the elastic member are respectively abutted against the first body and the coupling member; The second ring groove is disposed in the first ring groove, and the second side groove is limited to the buckle ring, and the second side is limited to the buckle ring. The ring groove limits the maximum stroke of the displacement of the coupling such that the coupling is constrained by the buckle without being disengaged from the first body.

The first system is provided with only one coupling member and a buckle. The first body can be sleeved with a plurality of different second bodies by the coupling member, so that one of the replacement wrenches can be combined with the buckle and the buckle. Save on component costs. During the processing of the first body, the first system drills the first bonding hole, then taps and turns the first ring groove and then punches out the socket groove. The first body processing cost is relatively low. The joint member is screwed to the first joint hole of the first body, and the tolerance between the sleeve groove and the sleeve portion is only the screwing or screwing of the joint member to make the socket portion and the socket portion Slot phase sleeving. Referring to the seventh figure, the joint is limited to the buckle and is not disengaged from the first body. The buckle limits the maximum displacement stroke of the joint, and the joint is not lost.

The structure and composition of the present invention are described in conjunction with the drawings and the drawings, and the following description is only for explaining the implementation of the present invention. For example, it is not intended to limit the invention in any way, and any modifications made by the present invention are still within the scope of the invention.
