Description
Technical field
The invention belongs to technical field of tools, relate to a kind of screwdriver and protective jacket, particularly a kind of Foldable screwdriver and protective jacket.
Background technology
Existing screwdriver mostly is single head, user needs to prepare multiple screws cutter could meet productive life needs, and therefore manufacturer develops multi-bit screwdriver, is wherein divided into Foldable screwdriver and bit screwdriver of living, live when bit screwdriver uses and need to change cutter head, use inconvenience and processing cost is high; Foldable screwdriver usually in the handle between the knife bar of multiple band different size cutter head is set, difficulty of processing is low and easy to use, but in use, owing to not arranging the fixed structure to knife bar, therefore in use, knife bar easily overturns, and reduces production efficiency, simultaneously easily damages user.
Summary of the invention
The object of this invention is to provide a kind of structure simple, easy to operate and the Foldable screwdriver that cost is low and protective jacket.
For achieving the above object, the present invention by the following technical solutions: Foldable screwdriver, comprises a pair fixed head, is provided with segmentation axle between fixed head mid point, and fixed head is provided with fixed axis between end, and two fixed axis are all rotatably connected to some knife bars; Arbitrary knife bar side is connected with pad, and pad is provided with several draw-in grooves; The axis matched with draw-in groove is also connected with between fixed head.
Further, axis two ends are connected with the slide that fixed head is arranged; One end of chute is provided with installing hole.
Further, fixed head is provided with torsion spring draw-in groove, and be provided with torsion spring in torsion spring draw-in groove, torsion spring matches with axis; Chute is also provided with the semifixed groove of axis of arc.
Further, axis is arranged with axis pad; The diameter of installing hole is greater than the diameter of axis pad and axis.
Further, handle is provided with outside fixed head.
Further, two groups of knife bars are connected to respectively cruciate flower cutter head peace cutter head.
Further, Foldable screwdriver protective jacket is the bag shaped structure of one end open, and its side is provided with depressed part, is provided with survey electric installation in depressed part.
Further, bag shaped structure is soft insulating material.
Compared with prior art, beneficial effect of the present invention is as follows: be provided with separation axis between fixed head mid point, and two groups of knife bars separate by separation axis, saves space, avoids two groups of knife bars influence each other and can make knife bar marshalling, more attractive in appearance; Arbitrary knife bar side is connected with pad, pad is provided with several draw-in grooves, the axis matched with draw-in groove is also connected with between handle, when needing to use a certain cutter head, can axis be stuck in draw-in groove, user use screwdriver work time, because knife bar is fixed by axis, knife bar can not overturn when stressed, increases work efficiency and avoids knife bar upset injury user in work; Axis two ends are connected with the slide that fixed head is arranged, and axis can along slide, and structure is simple and easy to use; Fixed head is provided with torsion spring draw-in groove, torsion spring is provided with in torsion spring draw-in groove, torsion spring matches with axis, torsion spring pushes down axis, makes the axis when not working be in being fixed by knife bar foremost of chute, and during work, user stirs axis and makes it depart from draw-in groove, when knife bar turns to operating position, unclamp axis, reset to chute at torsion spring effect lower fastening axle and be stuck in foremost in draw-in groove, structure is simple and easy to use; One end of chute is provided with installing hole, and the diameter of installing hole is greater than the diameter of axis pad and axis, can directly axis and pad be installed through installing hole, easy to operate; Chute is also provided with the semifixed groove of axis of arc, axis can be moved in use in the semifixed groove of axis, now due to torsion spring effect, axis can rest in the semifixed groove of axis, when knife bar is turned to operating position, move in chute by axis from the semifixed groove of axis, axis can be got back to chute and be fixed knife bar foremost under torsion spring effect, easy to operate; Two groups of knife bars are connected to respectively cruciate flower cutter head peace cutter head, the cutter head of the many specifications of multiple types can be provided for user, easy to use; Protective jacket is the bag shaped structure of one end open, its side is provided with depressed part, survey electric installation is provided with in depressed part, arrange depressed part to match with the non-usage space in Foldable screwdriver, reduce volume of the present invention, survey electric installation simultaneously and can carry out livewire work, improve security, increase the scope of application; Protective jacket is soft insulating material, effectively can improve security.

Detailed description of the invention
Foldable screwdriver, comprises a pair fixed head 5, and be provided with segmentation axle 8 between fixed head 5 mid point, fixed head 5 is provided with fixed axis 7 between end, and two fixed axis 7 are all rotatably connected to some knife bars 10; Arbitrary knife bar 10 side is connected with pad 1, and pad 1 is provided with several draw-in grooves 2; The axis 6 matched with draw-in groove 2 is also connected with between fixed head 5.The chute 16 that axis 6 two ends and fixed head 5 are arranged is slidably connected; One end of chute 16 is provided with installing hole 15.Fixed head 5 is provided with torsion spring draw-in groove 12, is provided with torsion spring 9 in torsion spring draw-in groove 12, and torsion spring 9 matches with axis 6; Chute 16 is also provided with the semifixed groove 14 of axis of arc.Axis 6 is arranged with axis pad 13; The diameter of installing hole 15 is greater than the diameter of axis pad 13 and axis 6.Handle 4 is provided with outside fixed head 5.Two groups of knife bars 10 are connected to respectively the peaceful cutter head 11 of cruciate flower cutter head 3.Foldable screwdriver protective jacket 17 is the bag shaped structure of one end open, and its side is provided with depressed part 18, is provided with and surveys electric installation 19 in depressed part 18.Bag shaped structure is soft insulating material, and bag shaped structure is provided with opening and survey electric installation 19 can be contacted with Foldable screwdriver.
When not using screwdriver, upset knife bar 10, knife bar 10 and cutter head are in the spatial accommodation that fixed head 5 formed, when needing to use screwdriver, axis 6 is stirred backward and is stuck in the semifixed groove 14 of axis, unclamp axis 6, now axis 6 is pressed in the semifixed groove 14 of axis by torsion spring 9, rotate selected knife bar 10, make it with fixed axis 7 for axle center spins out, and stop in place, if the angle between fixed head 5 is 90 °, 135 ° or 180 °, now axis 6 is released from the semifixed groove 14 of axis, under torsion spring 9 acts on, axis 6 reset to chute 16 foremost and be stuck in draw-in groove 2, complete fixing knife bar 10, after finishing using, again axis 6 is moved in the semifixed groove 14 of axis, rotating knife bar 10 makes it pack up.When not using screwdriver, screwdriver can be placed in protective jacket 17, when needing hot line job or survey electricity, first protective jacket 17 is taken off, when knife bar 10 forwards use location to, then by protective jacket 17 on screwdriver, now survey electric installation 19 and contact with screwdriver, screwdriver all the other each parts except handle all adopt conductive material, can carry out carrying out survey electricity by cutter head.
