Abstract
The utility model discloses a screwdriver bit, which comprises a handle part, and a cutter head part, wherein the handle part is clamped by a clamping device of an electric power tool so as to be driven to rotate, and is provided with a polygon column; the cutter head part is provided with a polygonal hole matched with the polygon column, and can be driven by the handle part to rotate; the handle part and the cutter head part are separable; and a permanent magnet is arranged on the handle part. Through the screwdriver bit with magnetism, a screw can be stabilized by an operator conveniently.
Description
Technical field
The application relates to a kind of screwdriver bit, relates in particular to the magnetic screwdriver bit of a kind of tool.
Background technology
Screwdriver bit is the tool heads part of hand screwdriver or electric screw driver and power drill.While using screwdriver bit to turn screw, conventionally first need to stablize screw, to prevent that screwdriver bit from skidding or preventing screw displacement.During use, operator can use one or two finger to stablize screw conventionally, then with screwdriver bit, turns screw.But along with the rotation of screw, screw likely can skid at surface of the work, and from operator is hurt.In addition, screw is being back-outed and made from workpiece, screw often drops from screwdriver bit, thereby makes operation inconvenience.
For addressing the above problem, conventional way is in the industry, makes screwdriver bit have magnetic.So, when using screwdriver bit to turn screw, can make screw be adsorbed on screwdriver bit, can make like this screw by the stable workpiece that is screwed into.And when screw is screwed out workpiece, it can be adsorbed on screwdriver bit, can not drop.
Therefore, making screwdriver bit have magnetic, is a kind of very important function.
At this, the application will provide a kind of new tool magnetic screwdriver bit.
Utility model content
The application aims to provide the magnetic screwdriver bit of a kind of tool.
For this reason, the application provides a kind of screwdriver bit, and it comprises, shank, and in order to be driven and to rotate by the clamping of the clamping device of electric tool, it is provided with polygon post; Cutter head portion, is provided with the polygonal hole coordinating with the polygon post of shank, can be driven and rotate by shank; Wherein, above-mentioned shank and cutter head portion are detachable, are provided with permanent magnetic patch on shank.
Therefore, the application, for user provides a kind of tool magnetic screwdriver bit, makes screwdriver bit have magnetic by permanent magnetic patch, can make operator be convenient to stablize screw.
Accompanying drawing explanation
Fig. 1 is according to the stereogram of the first screwdriver bit of the first embodiment of the application;
Fig. 2 is according to the profile of the first screwdriver bit of the first embodiment of the application;
Fig. 3 is according to the stereogram of the second screwdriver bit of the second embodiment of the application;
Fig. 4 is according to the stereogram of the second screwdriver bit of the second embodiment of the application;
The specific embodiment
As shown in Figure 1-2, the first screwdriver bit 10, the first screwdriver bits 10 for the first embodiment of the present invention comprise the first shank 12, the first cutter head portion 14 and the first permanent magnetism piece 16.Wherein the first shank 12 and the first cutter head portion 14 are divided into two parts.
The first shank 12 comprises the first retained part 124 in order to be clamped by the clamping device of electric tool and is used to the hexagonal prism of the first order 122 that the first cutter head portion 14 coordinates.The medium position of the first shank 12 is also provided with a shrinkage pool 126.Wherein above-mentioned the first permanent magnetism piece 16 is contained in above-mentioned shrinkage pool 126.
The first cutter head portion 14 comprises for the cutter head 144 of adaptive screw and the first hexagonal hole 142 of coordinating with the first protuberance 122 of above-mentioned the first shank 12.
During assembling, the hexagonal prism of the first order 122 of the first shank 12 inserts in the first hexagonal hole 142 of the first cutter head portion 14.After insertion, the first shank 12 can drive the first cutter head portion 14 to rotate, thereby turn screw, rotates.
In the shrinkage pool 126 of the first shank 12, contain one first permanent magnetism piece 16, so, the hexagonal prism of the first order 122 at the first shank 12 inserts after the first hexagonal hole 142 of the first cutter head portion 14, the first screwdriver bit 10 of present embodiment will integral body have magnetic, so, screw just can be adsorbed on the first cutter head portion 14 of the first screwdriver bit 10.So, making operator turn very easily screw rotates.
As shown in Figure 3-4, the second screwdriver bit 20, the second screwdriver bits 20 for the second embodiment of the present invention comprise the second shank 22, the second cutter head portion 24 and the second permanent magnetism piece 26.Wherein the second shank 22 and the second cutter head portion 24 are divided into two parts.
The second shank 22 comprises the second retained part 224 in order to be clamped by the clamping device of electric tool and is used to the second hexagonal prism 222 that the second cutter head portion 24 coordinates.Wherein, above-mentioned the second permanent magnetism piece 26 is magnet ring, is sheathed on above-mentioned the second hexagonal prism 222.
The second cutter head portion 24 comprises for the cutter head 244 of adaptive screw and the second hexagonal hole 242 of coordinating with the second protuberance 222 of above-mentioned the second shank 22.
During assembling, first the second permanent magnetism piece 26 of magnet ring shape is sheathed on the second hexagonal prism 222, and then the second hexagonal prism 222 is inserted in the second hexagonal hole 242 of the second cutter head portion 24.After insertion, the second shank 22 can drive the second cutter head portion 24 to rotate, thereby turn screw, rotates.
Between the second shank 22 and the second cutter head portion 24, be provided with the second permanent magnetism piece 26 of magnet ring shape.So, the second screwdriver bit 20 of present embodiment will integral body have magnetic, and screw just can be adsorbed on the second cutter head portion 24 of the second screwdriver bit 20.So, making operator turn very easily screw rotates.
The equal two-part of the second screwdriver bit of the first screwdriver bit of above-mentioned the first embodiment and the second embodiment, is comprised of shank and cutter head portion two parts.By the hexagonal prism of shank and the hexagonal hole of cutter head portion, work in coordination.In other embodiments, other polygonized structure also can, as long as can allow shank drive cutter head rotation.Above-mentioned permanent magnetism piece is all arranged on shank, in the occasion that does not need magnetic, magnetic block can be taken off.Above-mentioned the first screwdriver bit and the second screwdriver bit can be all casting.
About a plurality of embodiment of the present invention, be described above, but the present invention is not intended to be limited to the embodiment of description above and accompanying drawing signal.The feature of describing about an embodiment is equally applicable to other embodiments of the invention, and the feature of different embodiment can mutually combine and form new embodiment.In the situation that do not depart from essence and the scope being limited by claim below, those skilled in the art can carry out various modifications and variation to above-described embodiment.
