Abstract
The utility model relates to a bushing assembly of an electric drill chuck, which comprises a body connected with a spindle of an electric drill motor, wherein, the body tilts axially and is provided with a plurality of clamping jaws. An open end of the body is tightly sheathed with a container liner; a thin rod part of a tool sleeve penetrates into the container liner to be incorporated into the body and clamped by the clamping jaw; the other end of the tool sleeve is provided with a tool inserting part for a tool head to be inserted on. The bushing assembly is used for making the electric drill capable of using a drill bit, a screwdriver or a sleeve and making the use of tools quick, labor-saving and convenient.
Description
The utility model is relevant with the clamping device of electric drill, refers to a kind of sleeve assembly of electric drill chuck especially.
Electric drill commonly use clamp structure, as shown in Figure 1, it mainly has a body that is connected with motor spindle, this body peripheral hardware one can only rotate in the original place turns a shell 2 and a fixed housing 3, and the interior ring of this body is established the jaw 4 of several squints, this jaw 4 can or be turned shell 2 and control it and obliquely advance or shrink back by the nut of this clamp structure inside, reaches drill bit or bottle opener 5 clampings or unclasps.
The electric drill clamp structure of commonly using, its scope of application generally is only limited to clamping drilling bit, and the clamping face of jaw 4 can clipping in the round body of drill bit, when power or torsion became big if drill bit is hampered, maximum jaws 4 trackslipped in drill bit circle body surface, are unlikely destruction jaw 4.But if will be with these jaw 4 clamping hex tool heads (as screwdriver head), owing to the folder face of this jaw and the hex surface of inapplicable corresponding instrument body, so its clipping strength probably has deficiency; And if clamping reluctantly, when tool heads is hampered power or torsion when becoming big on, this jaw can't grip tool heads, the phenomenon that jaw slides in the hexagonal body surface of tool heads takes place, the clamped surface of this jaw 4 can be destroyed by the hexagonal body of instrument, even strength will make jaw expand, be out of shape, walk improperly, the clipping precision of jaw be reduced, even can't re-use.
Main purpose of the present utility model provides a kind of sleeve assembly of electric drill chuck, make the electric drill instrument no longer only limit to apply mechanically drill bit, also can be bottle opener and sleeve barrel tool, meet the design that most now instruments have the many merits of a thing, it is quicker, more laborsaving, more convenient that hand tools is used.
The purpose of this utility model is achieved in that a kind of sleeve assembly of electric drill chuck, has a body that is connected with the drill motor axle, this body axioversion is established several jaws, there is a shell to be coated outside it, be characterized in: the tight cover of this body open end one groove cover, the central authorities of groove cover have hole wholeheartedly to pierce into for the clamping end of this jaw, and an end of this groove cover is a sleeve part, and this sleeve part is established a polygonal notch; One instrument covers this groove cover of insertion and gos deep in this body, by this jaw clipping; The one end central authorities of this instrument cover extend and establish a thin rod part, and this thin rod part inserts in the heart hole of this groove cover and gripped by this jaw; The other end of this instrument cover is an instrument sleeve portion, for a tool heads sleeve on it.This instrument sleeve portion is arranged with a polygonal trepanning, and this tool heads is a screwdriver head, inserts in this polygonal trepanning; The end that this instrument cover portion that inserts lies in this instrument cover is extended and is protruded out one pulloverly, and this tool heads is a sleeve, this sleeve be placed in this pullover on; This instrument cover end face of this groove cover is relatively established one polygonal, for the polygonal notch that embeds this groove cover; A magnet is established in the deep of the polygonal trepanning of this instrument cover.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is illustrated.
Fig. 1 is a stereo appearance figure of commonly using electric drill.
Fig. 2 is the three-dimensional exploded view of the utility model first embodiment.
Fig. 3 is the assembled sectional view of the utility model first embodiment.
Fig. 4 is the three-dimensional exploded view of the utility model second embodiment.
Fig. 5 is the assembled sectional view of the utility model second embodiment.
See also Fig. 2, Fig. 3, electric drill chuck structure of the present utility model mainly has a body 10 that is connected with the drill motor axle, and these body 10 axioversions are established several jaws 11; Its peripheral hardware one shell 20 is coated.This jaw 11 can make axle drive when drill motor is started and control its advance and retreat when this body 10 rotates by a nut that is placed in outside it; Also can reach the action that control jaw 11 is advanced and retreat by rotating this shell 20.Above-mentioned technology and structure are located by prior art, and non-patent emphasis of the present utility model, do not add to give unnecessary details at this.
The tight sheathed groove cover 30 of these body 10 open end, the central authorities of this groove cover 30 are that wholeheartedly hole 31 supplies the clamping end of this jaw 11 to pierce into, one end of this groove cover 30 is a sleeve part, the inside and outside edge of this sleeve part forms a polygonal notch 33 and a spacing ring 34 respectively, can be respectively for doing the dismounting of nut and the axial location of this shell 20.
The heart hole 31 of this groove cover 30, a drill bit to these body 10 central authorities of can planting are inserted and put by this jaw 11.The instrument of also can in this heart hole 31, planting cover 40.
One end of this instrument cover 40 is established one polygonal 41, supplies to embed the polygonal notch 33 of this groove cover 30, and a thin rod part 42 extends in these end of polygonal 41 central authorities, grips for this jaw 11 in the heart hole 31 of this this groove cover 30 of thin rod part 42 insertions.The other end of this instrument cover 40 is an instrument sleeve portion, for sleeve one tool heads.
As Fig. 2,3, this instrument sleeve portion is arranged with a polygonal trepanning 43, and this tool heads is a screwdriver head 50, and the deep of this polygonal trepanning 43 fills a magnet 44 absorption and fixes this screwdriver head 50.
Fig. 4, Fig. 5 are the utility model second embodiment.This instrument cover 40 ' an end also be one polygonal 41 ' in the polygonal notch 33 of establishing this groove cover 30, its center also extend a thin rod part 42 ', the heart hole of the groove cover 30 of planting enters in the body 10 by these jaw 11 clippings; This instrument cover 40 ' instrument sleeve portion extend be convexly equipped with a rectangular block shape pullover 45 ', this tool heads is a sleeve 51, be placed in for sleeve 51 that this is pullover 45 ' on.
By above-mentioned design, this body 10 is driven by motor spindle, this jaw 11 can clamp this instrument cover 40,40 ', drive this instrument cover 40,40 ' rotation, simultaneously because of this instrument cover 40,40 ' go into polygonal notch 33 of this groove cover 30 by its polygonal 41,41 ' embedding system, therefore this groove cover 30 also has the auxiliary functions that this instrument cover 40 ' 40 rotates that drive, and this instrument cover 40,40 is rotated smoothly and can not get loose.
This instrument of pine oil cover 40,40 ' mode must decide on the clamp structure of electric drill.Can drive the counter-rotating of this motor spindle, make this jaw 11 shrink back can loosening this instrument cover 40,40 '.This shell 20 these jaws 11 of control that can reverse are shunk back.This also is a located by prior art partly, so do not add to give unnecessary details.
By above-mentioned structure, electric drill no longer only limits to the person of commonly using and uses drill bit, also can be bottle opener and sleeve barrel tool, meets the design that most now instruments have the many merits of a thing, and it is quicker, more laborsaving, more convenient that hand-held tool is used.
