Brief description of the drawings
Fig. 1 is the structural representation of the screwdriver of an embodiment；
Fig. 2 is that the schematic diagram after screw is taken out with the screwdriver shown in Fig. 1.
Embodiment
Referring to Fig. 1, an embodiment screwdriver 100, including screwdriver body 20 and protector 40.
Screwdriver body 20 includes knife bar 22 and is arranged at the cutter head 24 of the one end of knife bar 22.
In present embodiment, knife bar 22 and cutter head 24 are integral type structure.In a preferred embodiment, knife bar 22 and knife
First 24 are detachably connected, so as to change different types of cutter head 24 according to actual needs, to mount and dismount different type
Screw.
Knife bar 22 and being detachably connected for cutter head 24 can be accomplished in the following manner：Knife bar 22 be connected with cutter head 24 one
End offers mounting hole, and one end of cutter head 24 is contained in mounting hole and is fixed on by magnetic absorption in the mounting hole.
Knife bar 22 is cylinder shape knife rod.Cutter head 24 is a word cutter head, cross cutter head, rice word cutter head or star cutter head.This reality
Apply in mode, cutter head 24 is rice word cutter head.
Preferably, screwdriver body 20 also includes grip part 26.Grip part 26 is arranged at the one of the remote cutter head 22 of knife bar 22
End.Grip part 26 is set to be more convenient using the installation and removal screw of screwdriver 100.
Protector 40 includes fixture 42, threaded connector 44, the protective jacket 46 and elastic component 48 of both ends open.
Fixture 42 is arranged on knife bar 22.In present embodiment, the middle part of fixture 42 offers fixing hole, knife bar 22
Realize knife bar 22 with the tight fit of fixture 42 through fixing hole and be connected with fixture 42.
Two through hole (not shown) are further opened with fixture 42.
Threaded connector 44 is used for the protective jacket 46 of connection fixture 42 and both ends open.Threaded connector 44 includes connection
Portion and the head being connected with connecting portion, the one end on the remote head of connecting portion are formed with screw thread, and connecting portion is passed through on fixture 42
Through hole, the one end on the remote head of connecting portion is threadedly coupled with protective jacket 46, one end of the close connecting portion on head and fixation
Part 42 is abutted.The opposed fixed member 42 of the one end on the close head of connecting portion may move.
In present embodiment, threaded connector 44 is two.Preferably, threaded connector 44 is bolt, further preferably
For M4 bolts.
One end of protective jacket 46 offers two screwed hole (not shown).Each threaded connector 44 sequentially passes through each logical
Hole and each screwed hole and be threadedly coupled fixture 42 and protective jacket 46.Cutter head 24 stretches into anti-from an openend of protective jacket 46
In sheath 46.The internal diameter of two through holes is preferably 5mm.Screwed hole is preferably M4 internal thread holes.
In present embodiment, protective jacket 46 has been internally formed shoulder hole, and the two ends of shoulder hole are two of protective jacket 46
Openend.Shoulder hole includes macropore 462 and the aperture 464 connected with macropore 462.Macropore 462 and aperture 464 are coaxial.Screwed hole
It is opened on the jacket wall of close aperture 464 of protective jacket 46, screwed hole prolongs from the top of jacket wall to the direction close to macropore 462
Stretch.The axis of screwed hole and the diameter parallel of aperture 464.
Preferably, the big 1mm of diameter of the aperture ratio knife bar 24 of aperture 464, the aperture of macropore 462 is pacified using screwdriver 100
The big 2mm of diameter in the semicircle bulb of the screw of assembly and disassembly so that screwdriver body 20 is rotated flexibly, screw pass in and out protective jacket 46 compared with
For convenience, do not block, with the screw that is easy for installation and removal, and make the small volume of protective jacket 46 so that screwdriver 100 is applied to narrow
Small space.
Elastic component 48 is two.Each elastic component 48 is sheathed on the outside of each threaded connector 44, and each elastic component
48 one end is connected with fixture 42, and the other end is connected with protective jacket 46.Two elastic components 48 are helical spring.Preferably,
Helical spring is the little spring of elastic force, so that during installation and removal screw, protective jacket 46 is more gentle along moving for knife bar 22,
So that the screwdriver 100 will not because be provided with protector 40 and mount and dismount screw when than traditional screwdriver expense
Power.
The threaded connector 44 of said structure can connection fixture 42 and protective jacket 46, and in the effect of elastic component 48
Under, protective jacket 46 can be made to be moved along knife bar 22, and can prevent during screw is mounted and dismounted, threaded connector 44
Come off and cause protective jacket 46 to come off.
Referring to Fig. 2, in knockout screw 200, one end of the remote elastic component 48 of protective jacket 46 is fitted with lathe, another
End is close to fixture 42 due to the compression of elastic component 48, and threaded connector 44 is moved to the direction of grip part 26.Rotation is held
Portion 26 is held, because screw 200 is screwed out, protective jacket 46 is moved in the presence of elastic component 48 together with threaded connector 44, so that
Increased with the distance between fixture 42.When screw 200 is screwed out, due to the protection of protective jacket 46, it can prevent screw 200 from taking off
Fall.
In mounting screw 200, rotate the mounting screw 200 of grip part 26 during, the stress of protective jacket 46 and compress
Elastic component 48, and because threaded connector 44 is connected through a screw thread with protective jacket 46, thus drive threaded connector 44 together to
Move in the direction of grip part 26.When completing the installation of screw 200, protective jacket 46 returns to original position due to the active force of elastic component 48
Put.
Threaded connector 44 can also adjust protective jacket 46 with respect to knife in addition to can be with connection fixture 42 and protective jacket 46
First 24 overhang, so that screwdriver 100 is applied to the screw that installation and removal length differs, expands the suitable of screwdriver 100
Use scope.
Preferably, in the state of using the knockout screw 200 of screwdriver 100, screw 200 stretches out the part of protective jacket 46
Length is 2mm.
Above-mentioned screwdriver 100 includes protector 40, and protector 40 includes fixture 42, threaded connector 44, elasticity
The protective jacket 46 of part 48 and both ends open, is connected through a screw thread the connection fixture 42 of part 44 and protective jacket 46, and pass through elastic component
48 elastic force effect realizes protective jacket 46 along the displacement of knife bar 22 so that protective jacket 46 does not influence the installation and removal of screw, and by
In the protection of protective jacket 46, toner screw can be prevented.
Above-mentioned screwdriver 100 is simple in construction, can prevent toner screw, it is adaptable in narrow space and complicated housing construction
Lower installation and removal screw, it is convenient and swift, it is time saving and energy saving, maintenance time is saved, operating efficiency is improved.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope of this specification record is all considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and it describes more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that coming for one of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
