Description
Technical field
The present invention relates to the fastened tools in a kind of electromechanical tool field, be specially a kind of screwdriver with lever.
Background technology
Screwdriver is fastened tools conventional in electromechanical industries, is used for twisting screw and forces its instrument in place, conventionally has a thin sphenocephaly, can insert in the line of rabbet joint or recess of screw cap, mainly contain two kinds of a word and crosses, common hex(agonal)screw cutter in addition, comprises two kinds of interior hexagonal and outer-hexagonals.At present screwdriver mainly divides two kinds of normal screws cutter and combination type screwdrivers, wherein plain edition screwdriver is exactly that a handle is made screwdriver together, easily prepare, as long as just take out, can use, but because screw has a variety of different lengths and rugosity, sometimes need to prepare the screwdriver of a lot of Zhi Butong.Combination type screwdriver is a kind of screwdriver that cutter hub and handle are separated, and when dissimilar screw is installed, only cutter hub need to be changed, and does not need to prepare and carry a large amount of screwdrivers, and benefit is to save space, and shortcoming is easily to lose cutter hub.China Patent No. is 201120327509.9, the patent that name is called " a kind of screwdriver " arranges arc shell in cutter hub rear end, housing inner blocking type connects tool tip, a plurality of slots are offered on tool tip surface, in slot, assign cutter head, cutter head upper end is six prism structures, and lower end is cross or yi word pattern is protruding, the model of projection is different, and cutter head top is plugged in cutter hub front end groove and is adsorbed on the magnet of groove end face.During use, open bonnet, the cutter head of needs is taken out and is arranged in cutter hub front end groove and is adsorbed on magnet, hold cutter hub and select dress, owing to having stored the cutter head of Multiple Type in tool tip, can select as required, and needn't carry a large amount of screwdriver monomers, although facilitated user's use, but Shortcomings still: still need to carry in addition screw, cannot solve the problem that screw is easily lost, in addition, when twisting tighter screw, when the handle of a knife of the free-hand screwdriver of holding with a firm grip rotation are used, sometimes need to exert great efforts and screw or nail could be screwed down, if now residing working environment and oil phase close, staff's both hands are stained with oily time, when conventional screwdriver is used in rotation, have the sensation of exerting oneself nowhere, cannot tighten or unscrew screw, if need handwash operation repeatedly, greatly cause user's inconvenience.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of screwdriver with lever easy to use.The cutter head of this screwdriver set Multiple Type, saves space, easy to carry, the more important thing is and uses screwdriver process to help rotation to use with lever, to user, brings great convenience.
In order to solve the problems of the technologies described above, the present invention realizes by the following technical solutions:
A kind of screwdriver with lever, comprise that knife bar, handle and knife bar chamber form, knife bar is flexibly connected with Handle axis, knife bar chamber is for being arranged on an openable chamber on handle, it is characterized in that: described handle is provided with a through hole perpendicular to handle orientations near knife bar one end, in through hole, be provided with steel pipe or stainless steel bar, between described steel pipe or stainless steel bar and described through hole for removably connecting.
The cutter head of described knife bar can be yi word pattern or cross.
Described screwdriver knife bar segment length is set to 4-9cm, and handle segment length is set to 6-15cm; Preferably knife bar is 7cm, and handle is 13cm.
Knife bar of the present invention is flexibly connected with Handle axis, can pack a word knife bar or the cross knife bar of different model in knife bar chamber into, is convenient for changing, and also can pack screw into, solves user and carries inconvenient problem.When the tighter screw of twisting or user's both hands are stained with greasy dirt, can import steel pipe or stainless steel bar into through hole on handle, now adopt lever principle, only needing to rotate steel pipe or stainless steel bar can light turn screw, time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The 1st, knife bar, the 2nd, handle, the 3rd, knife bar chamber, the 4th, through hole, the 5th, steel pipe or stainless steel bar.
The specific embodiment
A kind of screwdriver with lever as shown in Figure 1, comprise that knife bar 1, handle 2 and knife bar chamber 3 form, knife bar 1 is flexibly connected with handle 2 axles, knife bar chamber 3 is for being arranged on an openable chamber on handle 2, one word knife bar or the cross knife bar that in knife bar chamber 3, can pack different model into, be convenient for changing, also can pack screw into, solve user and carry inconvenient problem; Handle 2 is provided with a through hole 4 perpendicular to handle 2 directions near knife bar 1 one end, in through hole 4, be provided with steel pipe 5 or stainless steel bar, 4 of described steel pipe or stainless steel bar 5 and described through holes are for removably connecting, when the tighter screw of twisting or user's both hands are stained with greasy dirt, can import steel pipe or stainless steel bar into through hole on handle, now adopt lever principle, only need rotation steel pipe or stainless steel bar to get final product light turn screw, time saving and energy saving.The cutter head of knife bar 1 is cross, and segment length is 7cm, and handle 2 is 13cm.
Above the present invention is described in detail, but the invention is not restricted to the embodiments described.The equivalence that all Spirit Essences according to the present invention are done changes or modifies, and all should be encompassed in protection scope of the present invention.
