Abstract
The utility model discloses a multi-purpose cross screwdriver. The middle part of the knife edge of the screwdriver is thin, the edge part of the screwdriver is thick, and the width of the knife edge gradually increases from the middle part of the knife edge to the edge part; the length of the cutter edge of the screwdriver is gradually reduced from top to bottom. The utility model discloses the design is novel, simple structure, and the screw of rotatable different specifications is used very conveniently.
Description
The utility model relates to a kind ofly uses Phillips screw driver more, is meant the Phillips screw driver that can rotate the model screw that varies in size specifically.
It is very limited that present Phillips screw driver, every handle revolve the screw specification of tool rotation, when rotation different size screw, must change and revolve tool.
The purpose of this utility model is to provide a kind of screw rotating tool of the rotatable specification that varies in size.
The utility model is design like this, and how thin with the edge of a knife middle part of Phillips screw driver, limit portion is thick, increases gradually to limit portion edge of a knife width from edge of a knife middle part, revolves the tool knife edge length and progressively reduces from top to bottom.
Below in conjunction with example shown in the drawings, the utility model is further described.
Accompanying drawing 1 is the schematic diagram of the utility model example;
Accompanying drawing 2 is the front view of screw rotating tool when rotation different size screw.
Among the figure: 1, use the Phillips screw driver edge of a knife more, 2, specification is the screw notch housing figure of 2mm, 3, specification is the screw notch housing figure of 3mm, 4, specification is the screw notch housing figure of 4mm, 5, specification is the screw notch housing figure of 5mm, 6, specification is the screw notch housing figure of 6mm, a, uses Philips screwdriver edge of a knife width more, b, uses the Philips screwdriver knife edge length more.
As can be seen, Multipurpose screw revolves tool edge of a knife middle part and approaches from accompanying drawing 2, and limit portion is thick, increases gradually to limit portion edge of a knife width from edge of a knife middle part; Revolving the tool knife edge length progressively reduces from top to bottom.And the screw of the specification that varies in size, its notch width from top to bottom increases gradually; Notch length also increases gradually.Like this, revolving the tool edge of a knife just can insert in the notch of different size screw.
From the above description as can be seen, the utility model can be designed to be applicable to the Phillips screw driver of different size scope, as 3～8mm scope, 3～10mm scope, 1～10mm scope, also can be designed to be applicable to the tool that revolves of all specification cross screws.
The utility model is novel, and is simple in structure, and the cross screw of rotatable different size uses very convenient.
