Abstract
The utility model relates to a drill chuck of adjustable length, bore the fixed drill chuck connecting rod A that sets up in collet body rear end, drill chuck connecting rod A goes up the equipartition and sets up through -hole A relatively, drill chuck connecting rod A goes up the slip cap and establishes drill chuck connecting pipe B, drill chuck connecting rod A rear end sets up outer convex ring, drill chuck connecting pipe B front end sets up inner convex ring, outer convex ring and inner convex ring cooperate, drill chuck connecting pipe B sets up through -hole B in the front portion relatively, the bolt passes upside through -hole B in proper order, with downside through -hole B threaded connection behind the relative through -hole A, the drill chuck connecting pipe B front end outside sets up the connection lagging, drill chuck connecting pipe B goes up the slip cap guard shield of seting up defences, the protection casing with be connected lagging threaded connection, still set up the air vent on the drill chuck connecting pipe B. The utility model discloses beneficial effect: convenient to use according to the length that the in -service use needs, adjusts the connecting length between drill chuck connecting rod A, the drill chuck connecting pipe B, has improved the work efficiency of drilling on long and narrow region or narrower pipeline.
Description
Technical field
This utility model is related to a kind of drill chuck, more particularly to a kind of length-adjustable drill chuck.
Background technology
Drill chuck is mounted in electric drill front end for the fixture of fixed drill bit, in some long and narrow regions or narrower pipeline
Upper drilling, because brachium is not enough and body can not be passed in and out flexibly, causes bore operation very inconvenient, and commonly used brill
The connection handle of chuck is shorter, just shorter in the rotating shaft of motor, drills on the pipeline in long and narrow region or narrower
Waste time and energy, work efficiency is relatively low.
Utility model content
Technical problem to be solved in the utility model is：A kind of length-adjustable drill chuck is provided, is solved above-mentioned
Technical problem.
This utility model is by solving the problems, such as the technical scheme for adopting set forth above：
A kind of length-adjustable drill chuck, including drill chuck body 1, drill chuck connecting rod A2, drill chuck connecting tube B3, spiral shell

It is upper uniformly to open up through hole A7 relatively, slide in drill chuck connecting rod A2 and be arranged drill chuck connecting tube B3, after drill chuck connecting rod A2
End arranges outer bulge loop 8, and drill chuck connecting tube B3 front end arranges internal projecting ring 9, and outer bulge loop 8 is engaged with internal projecting ring 9, and drill chuck connects
Adapter B3 is anterior relative to open up through hole B10, bolt 4 sequentially pass through after side through hole B10, relative through hole A7 with lower side through hole
B10 is threadedly coupled, and drill chuck connecting tube B3 front end outer side arranges connection sleeve plate 5, and slip cap is set up defences shield in drill chuck connecting tube B3
Cover 6, protective cover 6 is threadedly coupled with connection sleeve plate 5, and passage 11 is also opened up in drill chuck connecting tube B3.
Described bolt 4 is hexagon socket head cap screw, is easy to be threadedly coupled bolt with drill chuck connecting tube B.
Skid resistant course 12 is set on described protective cover 6, and be easy for installation and removal protective cover.
Described skid resistant course 12 is rubber antiskid layer, with preferable skidproof effect.
Operation principle of the present utility model：According to the length needed during actually used, adjust drill chuck connecting rod A,
Connecting length between drill chuck connecting tube B, is connected drill chuck connecting rod A, drill chuck connecting tube B by bolt.
The beneficial effects of the utility model are：1st, it is easy to use, can according to the length needed during actually used,
The connecting length between drill chuck connecting rod A, drill chuck connecting tube B is adjusted, is improve in long and narrow region or narrower pipeline
The work efficiency of upper drilling.2nd, bolt is hexagon socket head cap screw, is easy to be threadedly coupled bolt with drill chuck connecting tube B.3rd, protect
Skid resistant course is set on cover, and be easy for installation and removal protective cover.4th, skid resistant course is rubber antiskid layer, with preferable skidproof effect.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1- drill chucks body, 2- drill chuck connecting rod A, 3- drill chuck connecting tube B, 4- bolts, 5- connection sleeve plates,
6- protective covers, 7- through hole A, 8- evaginations, 9- internal projecting rings, 10- through hole B, 11- passages, 12- skid resistant courses.
Specific embodiment
Embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings.
With reference to Fig. 1, a kind of length-adjustable drill chuck described in this specific embodiment, including drill chuck body 1, drill point
Head connecting rod A2, drill chuck connecting tube B3, bolt 4, connection sleeve plate 5 and protective cover 6, the rear end of drill chuck body 1 is fixedly installed brill
It is uniform in chuck connecting rod A2, and drill chuck connecting rod A2 to open up through hole A7 relatively, slide in drill chuck connecting rod A2 and be arranged brill
Chuck connecting tube B3, the outer bulge loop 8 of drill chuck connecting rod A2 rear end setting, drill chuck connecting tube B3 front end setting internal projecting ring 9, and outward
