Abstract
The utility model relates to a kind of labour-saving novel screwdriver, comprise screwdriver bit and handle, handle is the L shape structure be made up of long-armed and galianconism, this long-armed and outer end that is galianconism is all coaxially made one and is installed groove, equal plug-in mounting screwdriver bit in each installation groove, the model of these two screwdriver bits is different.The utility model structure is simple, low cost of manufacture, and main part directly can be produced by casting.By different moment, reaching labour-saving object, and the use under varying environment can be adapted to, by changing the autgmentability that different screwdriver bits reaches larger, and reaching labour-saving effect by the length directly increasing moment.
Description
Technical field
The utility model relates to electric power tool technical field, especially a kind of labour-saving novel screwdriver.
Background technology
Screwdriver is that a kind of being used for twists screw with the instrument forcing it in place, usually has a thin sphenocephaly, in the line of rabbet joint that can insert screw cap or recess.Mainly contain a word (negative sign) and cross (positive sign) two kinds, common also has hex(agonal)screw cutter, comprises interior hexagonal and outer-hexagonal two kinds.At present, screwdriver is as a kind of instrument generally used, and be all absolutely necessary in the work of all trades and professions one of instrument, and equally in life, screwdriver also plays important role.
But the use of screwdriver but can not reach the satisfied effect of people sometimes, such as faced by get rusty screw time, normal screws cutter is difficult to easily deal with problems; People often can run into the screw that the larger people of strength tightens in life for another example, have been difficult to when the people that strength is less dismantles; Also can run into the situation that screw can not fasteningly put in place in addition.In the face of these problems of often meeting, add the work difficulty of staff, affect operating efficiency.If adopt professional tool (such as shock driver) to solve the problem, but this professional tool price comparison is expensive, be difficult to buy.
In addition, the no screwdriver of different size, decreased food can limit it under various circumstances in use and normally use, and prepares too many different types of screwdriver simultaneously, there is again problems such as carrying inconvenience.
Summary of the invention
The purpose of this utility model be to provide a kind of design ingenious, rational in infrastructure, use flexible, easy to carry and labour-saving novel screwdriver.
The purpose of this utility model is realized by following technological means:
A kind of labour-saving novel screwdriver, comprise screwdriver bit and handle, it is characterized in that: handle is the L shape structure be made up of long-armed and galianconism, this long-armed and outer end that is galianconism is all coaxially made one and is installed groove, equal plug-in mounting screwdriver bit in each installation groove, the model of these two screwdriver bits is different.
And coaxial package insulation sleeve outside described L shape handle, the mounting groove for placing screwdriver bit for subsequent use is made on this insulation sleeve surface, and snap close is installed on insulation sleeve surface, and the bandage of this snap close is positioned at above mounting groove.
Advantage of the present utility model and good effect are:
1, this screwdriver adopts L shape structure, the upper and lower two ends of handle are all designed with the groove installing screwdriver bit, during use, the model of two screwdriver bits is usually different, be equivalent to the effect of two handle screwdrivers, be applicable to different occasion place to use, for staff provides convenience, be conducive to increasing work efficiency.
2, this screwdriver autgmentability is large, can change different screwdriver bits, both solve the problem needing a large amount of screwdriver, be convenient for carrying again, is especially applicable to outdoor study.
3, this screwdriver changes traditional staight shank shape handle into L shape, and when using short handle holding screw, long handle considerably increases moment, obviously laborsaving.
4, this screwdriver coaxial package insulation sleeve outside handle, facilitates staff's holding operation, while increase comfort, also add security, uses when being especially applicable to power department construction.
The insulation sleeve of 5, this screwdriver makes mounting groove, therefore multiple screwdriver bit for subsequent use can be placed, add the scope of application of this product, in addition, the design of snap close and bandage also can play fixation to screwdriver bit for subsequent use, it is avoided to drop out from insulation sleeve, although this design is simple, very practical.
6, this screwdriver simplicity of design is practical, and low cost of manufacture, is applicable to applying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the schematic diagram of screwdriver bit and handle.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.
A kind of labour-saving novel screwdriver, comprise screwdriver bit and handle 2, handle is the L shape structure be made into integration by long-armed 7 and galianconism 8, this long-armed and outer end that is galianconism is all coaxially made one and is installed groove, equal plug-in mounting screwdriver bit in each installation groove, the model of these two screwdriver bits is different, and it can be respectively in-line 6 and cross 1.
Coaxial package insulation sleeve 5 outside L shape handle, mounting groove 3 is made on this insulation sleeve surface, places screwdriver bit for subsequent use in this mounting groove, and snap close is installed on insulation sleeve surface, and the bandage 4 of this snap close is positioned at above mounting groove.
Using method of the present utility model is:
Before work, screwdriver bit is arranged on handle two ends.
When needing to install dissimilar screw, only screwdriver bit need be changed just passable, not needing to prepare and carry a large amount of screwdriver.
When dismounting screw compares effort, short handle holding screw can be used, utilize long handle to increase moment, reach labour-saving effect.
