So screwdriver long is more laborsaving than short screwdriver, screwdriver make use of the operation principle of wheel shaft when being followed closely for the turn of the screw, when taking turns bigger
It is more laborsaving, thus it is more laborsaving during the carefully screwdriver the turn of the screw of handle than using using the screwdriver of slightly handle, and electricity screws many at present
Knife can only match somebody with somebody a kind of edge of a knife, thus using being restricted, user experience is not high.
The content of the invention：
The technical problems to be solved by the invention are：A kind of simple structure is provided, it is easy to use and can effectively change various differences
The electricity screwdriver of type cutter head.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：
A kind of electricity screwdriver with interchangeable bit interface, includes handle body and cutter, and the handle body includes tail
End fixed part and anterior rotation section, the tail end fixed part are set to column surface structure and are provided with it for cutter afterbody
Fixed cutter fixing hole, the cutter is detachably connected fixation with cutter fixing hole, and the cutter fixing hole is set to interior many
The fixing hole of side shape, and resilient key is provided with the fixing hole, the afterbody of the cutter is set to outer with what fixing hole coordinated
Polygonal gland, and the pin-and-hole coordinated with resilient key is provided with gland, the anterior rotation section includes two activities
Bar, the lower end of the motion bar is movably connected in the cylindrical end portions of tail end fixed part, and two motion bars are with the post of tail end fixed part
Body axis are symmetrical arranged, and the motion bar does fan-shaped turning with the cylindrical end portions of tail end fixed part as support shaft in perpendicular
It is dynamic.
Preferably, the fixing hole of the cutter is set to inner hexagonal hole, the gland is set to outer-hexagonal gland.
Preferably, being provided with multiple crossover subs between the gland and fixing hole.
Preferably, the motion bar is set to cross section ovalize bar.
Preferably, the movable rod outer surface is provided with frosted layer.
Preferably, being provided with the attachment means that can be detachably connected both between two motion bar opposite side bodies of rod.
Preferably, the attachment means are set to connect the elastic noose in the middle part of a body of rod for motion bar wherein.
Preferably, being hinged fixation between the motion bar and tail end fixed part.
Compared with prior art, usefulness of the present invention is：The electricity screwdriver with interchangeable bit interface
Using the cutter being detachably connected with can change to handle and mutually the transformational structure docked, thus effectively realize cutter
Quick-replaceable, improves the scope of application, in addition, the motion bar design of handle effectively can apply rotary action power to handle so that turn
It is dynamic more laborsaving, using more convenient, thus with practicality higher, it is adapted to popularization and application.
Brief description of the drawings：
The present invention is further described below in conjunction with the accompanying drawings：
Fig. 1 is positive structure schematic of the invention；
Fig. 2 is the present invention looks up structural representation of handle body of the invention.
Specific embodiment：
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only
It is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
All other embodiment that personnel are obtained under the premise of creative work is not made, belongs to the scope of protection of the invention：
A kind of electricity screwdriver with interchangeable bit interface as shown in Figure 1 and Figure 2, including handle body and cutter 1,
The handle body includes tail end fixed part 2 and anterior rotation section, the tail end fixed part 2 be set to column surface structure and
The cutter fixing hole 3 fixed for the afterbody of cutter 1 is provided with it, the cutter 1 is detachably connected fixation with cutter fixing hole 3,
The cutter fixing hole 3 is set to internal polygon fixing hole, and resilient key is provided with the fixing hole, the cutter 1
Afterbody is set to the outer polygonal gland 4 coordinated with fixing hole, and the pin coordinated with resilient key is provided with gland 4
Hole, the anterior rotation section includes two motion bars 5, and the lower end of the motion bar 5 is movably connected in the cylinder of tail end fixed part 2
End, two motion bars 5 are symmetrical arranged with the column axis of tail end fixed part 2, and the motion bar 5 is with the post of tail end fixed part
Fan-shaped rotation is done in perpendicular for support shaft in body end portion.
Thus in actual applications, inner hexagonal hole is set to by by the fixing hole of the cutter 1, the gland 4 sets
Outer-hexagonal gland is set to, is conveniently made and the stability between cutter and fixing hole is more preferable.
