The method of clamping of conventional electric drill is generally claw clamping.Electric drill comprises chuck, arranges the claw of three radial equipartitions in this chuck, utilize the key actuated spindle lock of peripheral hardware or activity to clamp screwdriver bit, or the tapered sleeve relative movement that driving itself is provided with is to clamp screwdriver bit.Adopt the structure of the chuck of above-mentioned prior art, when being replaced with screwdriver bit or other tool heads of other types, need to utilize key actuated spindle mobility or manually drive tapered sleeve to change, comparatively loaded down with trivial details, change efficiency lower; The chuck of jack catchs type in addition, utilize frictional force by screwdriver bit or tool heads clamping, its steadiness is poor, in use easily breaks down.
Therefore, in prior art, people have developed a kind of electric drill extension apparatus, and this electric drill extension apparatus is installed on the chuck of electric drill.It comprises chuck installation cavity, hollow connecting rod and screwdriver bit installation cavity, and chuck installation cavity outer wall shrinks the one end forming hollow connecting rod, and the other end outer wall of hollow connecting rod shrinks and forms screwdriver bit installation cavity.The flaky magnet that diameter equals screwdriver bit installation cavity inner diameter is provided with in this screwdriver bit installation cavity, the distance of this flaky magnet and screwdriver bit installation cavity accent is less than the length of screwdriver bit, when being installed to screwdriver bit installation cavity after screwdriver bit is replaced, a sucking action is arranged at the bottom of flaky magnet to screwdriver bit, fixing of further reinforcement screwdriver bit, improves the steadiness that screwdriver bit is installed.Even if be provided with flaky magnet, but it carries out spacing to the bottom of screwdriver bit, and the situation of micro-angular slope often can occur the screwdriver bit after installation, therefore needs the apparatus for correcting researching and developing a kind of rectification screwdriver bit for electric drill extension apparatus.
Utility model content
The purpose of this utility model is to provide a kind of apparatus for correcting for electric drill extension apparatus, and the screwdriver bit after installation is not tilted, and also improves the steadiness that screwdriver bit is installed, easy to use.
In order to realize above-mentioned utility model object, technical solutions of the utility model are as follows:
For an apparatus for correcting for electric drill extension apparatus, be installed on electric drill extension apparatus, it comprises a ringshaped magnet and corrects sleeve, and described ringshaped magnet is installed on rectification sleeve, and described jacket jacket casing is connected to electric drill extension apparatus.
Further, the external diameter of described ringshaped magnet equals the internal diameter correcting sleeve, and the internal diameter of described ringshaped magnet equals the external diameter of screwdriver bit.
Further, described rectification sleeve is provided with the first symmetrical otch and the second otch, described first otch and the second otch are arranged at one end of the rectification sleeve near electric drill extension apparatus.
Further, the other end of described rectification sleeve is provided with anti-skidding friction striped.
Further, described rectification sleeve is also provided with the buckle for coordinating with the draw-in groove of electric drill extension apparatus near one end of electric drill extension apparatus.
The apparatus for correcting for electric drill extension apparatus that the utility model proposes, when being installed to the screwdriver bit installation cavity of electric drill extension apparatus after screwdriver bit is replaced, a sucking action is arranged at the bottom of flaky magnet to screwdriver bit, strengthen the fixing of screwdriver bit, improve the steadiness that screwdriver bit is installed, meanwhile, utilize ringshaped magnet and the rectification upper end of sleeve to screwdriver bit to fix, ringshaped magnet also further enhances the fixing of screwdriver bit, improves the steadiness that screwdriver bit is installed.Rectification sleeve and electric drill extension apparatus are slidably matched, and it slides up and down as linear slide, and then can correct the setting angle of screwdriver bit, make screwdriver bit keep straight line, avoid the situation of the micro-angular slope of screwdriver bit, be convenient to the proper use of of screwdriver bit, improve the service life of screwdriver bit.
Accompanying drawing explanation
Fig. 1 is the structural representation after electric drill extension apparatus of the present utility model installs apparatus for correcting.
Fig. 2 is the schematic diagram that electric drill extension apparatus of the present utility model installs apparatus for correcting.
In figure, Reference numeral is: 1, electric drill extension apparatus, 2, flaky magnet, 3, draw-in groove, 4, ringshaped magnet, 5, correct sleeve, 6, buckle, and the 7, first otch, the 8, second otch, 9, screwdriver bit, 10, anti-skidding friction striped.
Detailed description of the invention
Be described in further details technical solutions of the utility model below in conjunction with drawings and Examples, following examples are not formed restriction of the present utility model.
As illustrated in fig. 1 and 2, the apparatus for correcting for electric drill extension apparatus of the present utility model, is installed on electric drill extension apparatus 1.Comprise a ringshaped magnet 4 and correct sleeve 5.
Wherein, the external diameter of ringshaped magnet 4 equals the internal diameter correcting sleeve 5, and the internal diameter of ringshaped magnet 4 equals the external diameter of screwdriver bit 9.When in the screwdriver bit installation cavity that screwdriver bit 9 is installed on electric drill extension apparatus 1, ringshaped magnet 4, to its limited location effect, makes it keep straight line, and the general material of screwdriver bit 9 is iron, can magnetic attraction with ringshaped magnet 4, strengthens the installation steadiness of screwdriver bit 9 further.
Correct on sleeve 5 and be provided with the first symmetrical otch 7 and the second otch 8, this first otch 7 and the second otch 8 are arranged at one end of the rectification sleeve 5 near electric drill extension apparatus 1.When rectification sleeve 5 is inserted in electric drill extension apparatus 1, the first otch 7 and the second otch 8 slightly softened, make rectification sleeve 5 have micro-elasticity, can not damage correct sleeve 5.
Correct sleeve 5 to be socketed with electric drill extension apparatus 1, correcting sleeve 5 can linear slide on electric drill apparatus for correcting 1, and make screwdriver bit 9 keep straight line, therefore, in order to slide conveniently, the one end away from electric drill extension apparatus 1 of correcting sleeve 5 is provided with anti-skidding friction striped 10.Certainly, anti-skidding friction striped 10 is wherein a kind of embodiment of the present utility model just, can also have the embodiment of other types, such as, and nonskid coating etc.
Correct after sleeve 5 be socketed with electric drill extension apparatus 1, correct sleeve 5 and be also provided with buckle 6 for coordinating with the draw-in groove 3 of electric drill extension apparatus 1 near one end of electric drill extension apparatus 1, spacing for rectification sleeve 5.Specifically, this buckle 6 be correct sleeve 5 edge extend internally formed projection.
Above embodiment is only in order to illustrate the technical solution of the utility model but not to be limited; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
