Iron plate type spanners

Abstract

The invention relates to an iron plate type wrench, comprising a body which is punched and formed directly by an iron plate; an upper press sheet and a lower press sheet which are respectively pressed and arranged at two sides of the body and which are respectively provided with a hole and a fixing hole which are respectively corresponding to a containing hole and a fixing hole in the body; a driving part with a flange at one end and a buckling slot at the other end, and the driving parts sequentially penetrate the hole in the upper press sheet, the containing hole in the body and the hole in the lower press sheet, the flange is blocked and arranged on the upper press sheet, and a fastener is buckled and arranged in the buckling slot to ensure that the driving part is combined with the body and the two press sheets, thus avoiding the shedding; a ratchet block which is arranged in the containing hole in the body; a fixing part which penetrate the fixing holes of the body and the two press sheets. The wrench of the invention has the advantages of reducing the processing cost of the wrench, having a longer griping part and being capable of bearing relatively large driving force as the thickness of the lower press sheet is more than that of the upper press sheet.

Description

technical field [0001] The invention relates to a wrench, in particular to a wrench capable of reducing labor costs, quick assembly and reduced machining. Background technique [0002] With reference to the Chinese patent application No. 200520063477.0 "Ratchet screwdriver", it includes a handle made by forging, at least one end of the two ends of the handle is provided with a ratchet structure, and the ratchet structure is made of It is composed of a shift block, a ratchet block and a trigger body; the forged handle is suitable for professional use, but the processing cost of forging is relatively high. Generally speaking, the single processing amount of forging is about 20,000 pieces , it is easy to have the problem of backlog of inventory. Moreover, this kind of wrench is processed by hot forging. After the hot forging is completed, it needs a lot of follow-up processing, and the delay of production time will greatly increase the processing cost, and the processing of pro...

Problems solved by technology

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an iron plate wrench, which improves the lack of the existing forged wrench, which is high in cost and consistent with the thickness of the plate wrench, and cannot provide the best effect of the wrench. At the same time, in order to satisfy the general consumer Low cost and taking into account the demand for quality of use
