In order to improve the high problem of above-mentioned cost, please refer to shown in Figure 2ly again, have the spanner 2 of elongated handle body for another kind.Described spanner 2 be connect respectively in the two ends of hollow handle body 3 establish one and half pull the end 4, can exempt the shortcoming that above-mentioned utilization forging mode is made by this, and also can save employed material.Yet described two pull the end 4 and hollow handle body 3 between be to connect in friction tight mode to establish, so on reality is used, can pull the problem of end 4 slippages in handle body 3, that is get loose or the shortcoming of retraction handle body 3, so plant design improved space is arranged still.
Summary of the invention
The object of the present invention is to provide a kind of lengthened type wrench joining structure, the technical problem that its desire solves is to be, existing spanner structure with elongated handle body, material consumption forms the too high problem of cost of material, and the degree of difficulty that is forged again is higher, forms the burden that system is produced cost, utilizes friction tight mode then to have to get loose easily or the problem of retraction handle body, be difficult to for the industry utilization, so urgently await improving.
To achieve these goals, the invention provides a kind of lengthened type wrench joining structure, it includes one first pulling piece, one second pulling piece and is received part; Described first pulling piece, one end is provided with a pulling part in order to switching screw or nut, and the end that first pulling piece differs from pulling part then forms a junction, and described connecting portion offers a fixed groove; One end of described second pulling piece is provided with a pulling part, and the other end then forms a connecting portion that is provided with fixed groove; The described part two ends of receiving all are provided with a link slot, described two link slots are to supply the connecting portion of described two pulling pieces to plug, then be equipped with a fixed portion with respect to the position of the fixed groove of described first pulling piece in described two link slots, in the fixed groove that is incorporated into described two pulling pieces; Make lengthened type wrench obtain a firm integrated structure by this, and in conjunction with after the part of receiving still have sliding suitable outer surface, not only be beneficial to gripping, have more product appearance attractive in appearance, effective stimulus consumer's desire to purchase.
The present invention has following advantage:
1. lengthened type wrench joining structure of the present invention, wherein said pulling piece is provided with fixed groove in connecting portion, is provided with fixed portion and receive part in link slot, and the described fixed portion of mat is incorporated in the fixed groove, obtains a firm integrated structure.
2. lengthened type wrench joining structure of the present invention, wherein said fixed groove can be made as and run through the connecting portion design of both sides up and down, and the both sides up and down in the described link slot are respectively equipped with a fixed portion, to be incorporated into the both sides up and down of fixed groove respectively, reach more firm in conjunction with effect.
3. lengthened type wrench joining structure of the present invention, wherein said receive part only a termination establish one first pulling piece, also but two ends connect respectively and establish first, second pulling piece, and the part of receiving after the combination still has sliding suitable outer surface, not only be beneficial to gripping, have more product appearance attractive in appearance, effective stimulus consumer's desire to purchase.
