Description
The utility model relates to novel screwdriver.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), moulding branch, hand-operated tools, portable power tools, the big class of the handle of hand instrument, being used for that other class is not wrapped is fastening, connection, dismounting or clamping tools or bench device group, the screwdriver technical group field.Be numbered B25B 15/00.
At present, the technology about screwdriver existing and that once had was all done very fruitful effort to the demand of novel screwdriver, also once designed many outstanding technical schemes.As expensively bravely declaring by hundred million of the Decree of Patent Office of China in 1996, Granted publication number is CN2232822Y, and China Patent No. (ZL) is: No. 95216712.3 utility model title is the utility model patent of " general-purpose screwdriver ", the technical scheme that is adopted.At the screwdriver technical elements is a routine of great value invention, and it has solved the problem of screwdriver general-purpose effectively.But still have some deficits, its also be difficult to solve very little slit screwdriver can't with the problem of machined surface vertical centering control tighten the screws.
The purpose of this utility model is to provide a kind of novel screwdriver.With solve very little slit screwdriver can't with the problem of machined surface vertical centering control tighten the screws.
The purpose of this utility model is achieved in that the novel screwdriver of this utility model.Mainly constitute by rotary cutter, immovable support, handle, hold-down screw, draw bail.Its major part hold-down screw is by selecting for use on the market.Its rotary cutter is optional shape, makes material with steel, through the heat treatment process manufacturing.Its immovable support is a cylindrical shape, makes material with steel, through the heat treatment process manufacturing.Its handle is a cylindrical shape, makes material with timber, through the processing and forming manufacturing.The rotary cutter of its optional shape adopts hinge method to be installed on the immovable support of cylindrical shape.Form the rotary cutter structure of an optional shape.The immovable support of its cylindrical shape adopts screw pair method to be installed on the handle of cylindrical shape.Form the immovable support structure of a cylindrical shape.Swivelling tool-holder one end of its flat pattern adopts the screw tightening method to be installed on immovable support one side of groove shapes, forms the swivelling tool-holder syndeton of a flat pattern.The first end of the rotating knife of its flat pattern adopts the screw method to be installed on the immovable support of groove shape shape.Form the rotary cutter syndeton of a flat pattern.Its swivelling tool-holder is by the hinged rotary cutter that acts on.Thereby make rotary cutter satisfy the requirement of processing.Its handle passes through the screw side effect in swivelling tool-holder.Thereby make handle finish the task of rotation.So just realized the purpose of this utility model.
The utility model has been compared three advantages and improvement with original screwdriver technology;
The first, because the utility model has designed rotary cutter in technical scheme, so solved rotatable removable problem;
The second, because the utility model has designed hold-down screw in technical scheme, so solved the fixedly problem of the anglec of rotation;
The 3rd, because the utility model has designed handle in technical scheme, so but solved the problem that screw is tightened in the dead axle rotation.Thereby just can more effectively solve very little slit screwdriver can't with the problem of machined surface vertical centering control tighten the screws.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the agent structure schematic diagram of novel screwdriver of the present utility model;
Fig. 2 is the local amplification profile structural representation of novel screwdriver of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 rotary cutter, 2 immovable supports, 3 handles, 4 hold-down screws, 5 draw bails
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, novel screwdriver of the present utility model.Mainly constitute by rotary cutter 1, immovable support 2, handle 3, hold-down screw 4, draw bail 5.Its major part hold-down screw 4 is by selecting for use on the market.Its rotary cutter 1 is optional shape, makes material with steel, through the heat treatment process manufacturing.Its immovable support 2 is cylindrical shapes, makes material with steel, through the heat treatment process manufacturing.Its handle 3 is cylindrical shapes, makes material with timber, through the processing and forming manufacturing.The rotary cutter 1 of its optional shape adopts hinge method to be installed on the immovable support 2 of cylindrical shape.Form the rotary cutter structure of an optional shape.The immovable support 1 of its cylindrical shape adopts screw pair method to be installed on the handle 3 of cylindrical shape.Form the immovable support structure of a cylindrical shape.Swivelling tool-holder one end of its flat pattern adopts the screw tightening method to be installed on immovable support 2 one sides of groove shapes, forms the swivelling tool-holder syndeton of a flat pattern.The first end of the rotating knife of its flat pattern adopts the screw method to be installed on the immovable support 2 of groove shape shape.Form the rotary cutter syndeton of a flat pattern.Its swivelling tool-holder is by the hinged rotary cutter 1 that acts on.Thereby make rotary cutter 1 satisfy the requirement of processing.Its handle 3 passes through the screw side effect in swivelling tool-holder 1.Thereby make handle 3 finish the task of rotation.So just realized the purpose of this utility model.Thereby just can solve very little slit screwdriver can't with the problem of machined surface vertical centering control tighten the screws.
Below by embodiment, the utility model is done more detailed description:
Realize that preferred plan of the present utility model is is material with steel, timber, utilize the basic equipment of machining factory, take heat treatment to produce in batch, the demand with supply daily life circle so just can realize practical value of the present utility model and economic worth better.
