Description

Multifunctional screw driver

The utility model relates to multifunctional screw driver.Belong to operation Department of Transportation, moulding branch, hand-operated tools by International Patent Classification (IPC) (IPC) division; Portable power tools; The handle of hand instrument; Workshop appliance; The big class of manipulator, other class is not to be covered to be used for fastening, connection, dismounting or clamping tools or bench device group, big group of the part of wrench, spanner, screwdriver or annex, screw or the little technical group field of nut head lighting device.Classification number is B25B23/18.

At present, existing and once had about big group of the part of wrench, spanner, screwdriver or annex, the technology of screw or nut head lighting device group was all done very fruitful effort to the demand of multifunctional screw driver, also once designed many outstanding technical schemes.As declaring by Liu Jiangxi is flat of the Decree of Patent Office of China in 1996, Granted publication number is CN2230202Y, and China Patent No. (ZL) is: No. 95217059.0 utility model title is the utility model patent of " dual-purpose screwdriver ", the technical scheme that is adopted.Big group of the part of wrench, spanner, screwdriver or annex, screw or nut head lighting device group technical elements are routine of great value inventions, and it has solved the problem of dual-purpose screwdriver effectively.But still have some deficits, its also very difficult solution is in the dark worked and is not had lamplit problem.

The purpose of this utility model is to provide a kind of multifunctional screw driver.There is not lamplit problem to solve in the dark to work.

The purpose of this utility model is achieved in that the multifunctional screw driver of this utility model.Mainly constitute by reflector, small electric bulb, switch, battery, torch shell, handle, spring, screwdriver rod, main light hole, secondary light hole.Its reflector, spring, small electric bulb, screwdriver rod, battery are by selecting for use on the market.Its switch is the elastic sheet shape, uses the steel material, through rolling processing and manufacturing.Its torch shell is the closed cylinder shape, uses the steel material, through the casting processing and manufacturing.Its handle is a drum, uses the steel material, through the casting processing and manufacturing.Its main light hole is a toroidal, with (optics) reflectorized material, through the cutting processing manufacturing.Its secondary light hole is the cylinder sandwich shape, reserves processing and manufacturing through installing.Spring adopts the screw-in method to be installed in the bottom position of torch shell, constitutes spiral-shaped supporting construction, and function has been to compress galvanic action.Battery adopts puts into the interior location that method is installed in the torch shell, constitutes the cylindrical shape electric power-feeding structure, and function has been a power supply function.Small electric bulb adopts the screw-in method to be installed in the front end middle position of torch shell, constitutes ball shape ray structure, and function has been luminous effect.The torch shell adopts the insertion method to be installed in the bottom center of handle, constitutes cylindrical shape torch structure, and function has been the light source effect.Reflector adopts the method for being screwed into to be installed in the apical position of handle, constitutes taper seat fixed in shape structure, and function has been fixedly torch and reflection action.Switch adopts the insertion method to be installed in the external position of handle, constitutes the cube shaped control structure, and function has been the on-off action of control lamp.Screwdriver rod adopts welding method to be installed in the bottom center position of handle, constitutes cylindrical shape spiral shell knife structure, and function has been the screwdriver effect.So just realized the purpose of this utility model.

The advantage of utility model: big group of the part of the utility model and original wrench, spanner, screwdriver or annex, screw or nut head lighting device group technology have been compared three advantages and improvement;

The first, because the utility model has designed screwdriver rod in technical scheme, so can be to operations such as screws;

The second, because the utility model has designed small electric bulb and main light hole in technical scheme, so can brightly check fault;

The 3rd, because the utility model has designed secondary light hole in technical scheme, so can be in the operation of dark place; There is not lamplit problem thereby just more effectively having solved in the dark works.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the main TV structure schematic diagram of multifunctional screw driver of the present utility model;

Fig. 2 is the plan structure schematic diagram of multifunctional screw driver of the present utility model;

The numbering of parts explanation in the schematic diagram: 1 reflector, 2 small electric bulbs, 3 switches, 4 batteries, 5 torch shells, 6 handles, 7 springs, 8 screwdriver rods, 9 main light hole 10 secondary light holes

In the optimum implementation of multifunctional screw driver of the present utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:

Its static structure: as shown in the figure, multifunctional screw driver of the present utility model.Mainly constitute by reflector 1, small electric bulb 2, switch 3, battery 4, torch shell 5, handle 6, spring 7, screwdriver rod 8, main light hole 9, secondary light hole 10.Spring 7 adopts the screw-in method to be installed in the bottom position of torch shell 5, constitutes spiral-shaped supporting construction, and function has been to compress galvanic action.Battery 4 adopts puts into the interior location that method is installed in torch shell 5, constitutes the cylindrical shape electric power-feeding structure, and function has been a power supply function.Small electric bulb 2 adopts the screw-in method to be installed in the front position of torch shell 5, constitutes ball shape ray structure, and function has been luminous effect.Torch shell 5 adopts the insertion method to be installed in the bottom center of handle 6, constitutes cylindrical shape torch structure, and function has been the light source effect.Reflector 1 adopts the method for being screwed into to be installed in the apical position of handle 6, constitutes taper seat fixed in shape structure, and function has been fixedly torch and reflection action.Switch 3 adopts the insertion method to be installed in the external position of handle 6, constitutes the cube shaped control structure, and function has been the on-off action of control lamp.Screwdriver rod 8 adopts welding method to be installed in the bottom center position of handle 6, constitutes cylindrical shape spiral shell knife structure, and function has been the screwdriver effect.

Its dynamic structure: in force:

According to principle of luminosity, its small electric bulb 2 acts on main light hole 9 by reflector 1, thereby finishes the task of the work of checking.According to reflective principle, its small electric bulb 2 acts on secondary light hole 10 by reflector 1, thereby finishes the task of modification.So just realized the purpose of this utility model.There is not lamplit problem thereby just having solved in the dark works.

Below by using method, the utility model is done more detailed description:

The multifunctional screw driver of this utility model is work like this:

In use, in the time of the light dark, can use as required.According to principle of luminosity, its small electric bulb 2 acts on main light hole 9 by reflector 1, thereby finishes the task of the work of checking.According to reflective principle, its small electric bulb 2 acts on secondary light hole 10 by reflector 1, thereby finishes the task of modification.

Realize that preferred plan of the present utility model is is material with the steel, utilize the basic equipment of small-sized five metals factory, take small lot to produce by batch, the demand with supply daily life circle so just can realize practical value of the present utility model and economic worth better.
