Technical field:
The utility model relates to the drill chuck on the hand-held drill gun, is suitable for the standby easily accessory combining of installation or removal of normal needs transposing.
Technical background:
Single button is outer to connect hand fastening drill clutch as one of a plurality of annexes of drill gun, the replacement annex that in use often needs the transposing use, going to once has the drill chuck of multiple different structure product, be threaded as useful, steel ball sealed etc., but it is desirable not enough to meet our the annex requirement that forms a complete set of, as connect trouble, and structure is complicated, and cost of manufacture is higher, concrete actual conditions from the present according to us are produced not only practicality but also the low outer drill chuck that connects of single button of cost of manufacture.
Summary of the invention:
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, and provides a kind of single button easy to operate, that be connected firmly the outer hand fastening drill clutch that connects.It is sealed that it adopts side direction to press the location of moving on the drill gun main shaft of lockplate; Collet body rear orifice end face is shaped on " ten " word breach and matches with " ten " word breach on the drill gun main shaft.
The utility model solves the technical scheme that above technical problem takes: the outer hand fastening drill clutch that connects of single button, comprise that the front portion is provided with three inclined holes, the rear portion has the collet body of endoporus, inserts three pinches of collet body front portion, with the interior flare nut of pinch top threaded engagement; Back casing, with the tight cover of interior flare nut and interior flare nut is inlaid in the groove of collet body, the procapsid rear portion is a back casing, it is characterized in that, is provided with lockplate, spring in the described back casing; Collet body rear orifice end face is shaped on " ten " word breach, can match with " ten " word breach on the drill gun main shaft; Being shaped on square hole in the middle of the described lockplate is linked on the rear end external diameter of collet body, the inboard, middle square hole lower end of lockplate is inlaid in the through hole of the collet body back lower place, and having part to expose in hole wall, this exposed part can be entrenched in when drill chuck is installed in the groove of drill gun main shaft; Inboard, square hole upper end is embedded with spring, spring push makes moving that lockplate can reset certainly in through hole on the outer diameter flat of collet body rear end, the lug boss activity of lockplate upper end is inlaid in the side opening of back casing external diameter one side, and have part to expose on the surface, be the button of pushing for hand.
The technical measures of optimizing also comprise:
The endoporus of above-mentioned back casing end face is shaped on the plane of symmetry, and the mutual tight fit of symmetrical plane on this plane and the collet body rear end external diameter is to guarantee that lockplate is constant with the relative seat of the installation of collet body to back casing.
The through hole that is interlinked to the outside in the place, plane at above-mentioned collet body rear portion is shaped on, the part of lockplate is inlaid in the through hole, and has part to expose on hole wall; The outer face in hole is shaped on " ten " word breach, is shaped on symmetrical plane on the external diameter in hole.
Above-mentioned lockplate is tabular, the centre be near as square hole, be sleeved on the external diameter at collet body rear portion, inboard, square hole upper end is embedded with spring, inboard, square hole lower end is inlaid in the through hole at collet body rear portion, and the lockplate upper end exposes in back casing external diameter one side for button.
Be shaped on through hole on the above-mentioned back casing one side external diameter, button is exposed at above the through hole outward; The endoporus of back casing is shaped on symmetrical plane, and end face is blocked by the ring washer that is fixed on the collet body rear portion; Be placed with spring before the end face, back casing can reset certainly.
Compare with present technology, advantage of the present utility model is: lockplate is sleeved on the external diameter at collet body rear portion, the button of lockplate is exposed at outward on the side external diameter of back casing, just can reach lockplate revealing maybe on collet body rear orifice wall can be flooded as long as push button, make drill chuck of the present utility model sealed on the drill gun main shaft or separate; Be shaped on " ten " word breach at collet body rear orifice end face, so that match with " ten " word breach on the drill gun main shaft, because above design feature, the utility model installation or removal are convenient, be connected firmly, and are rational in infrastructure.
Description of drawings:
Fig. 1 is the assembling half sectional view of the utility model embodiment.
Fig. 2 is Figure 1A-A cutaway view.
Fig. 4 is the front view of drill gun front end.
Fig. 3 is the cutaway view of Figure 1B-B.
The specific embodiment:
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Structure of the present utility model sees that Fig. 1 is to shown in Figure 4.Figure grade explanation: pinch 1, collet body 2, interior flare nut 3, procapsid 4, back casing 5, side opening 501, lockplate 6, button 601, cross breach 201, through hole 202, hole 203, symmetrical plane 204, spring 7, back-up ring 8.
The outer hand drill chuck of winning in succession of single button, collet body 2 front ends are shaped on the endoporus of three inclinations, are fitted with threaded three pinches 1 in the endoporus, by the interior flare nut of procapsid 4 tight covers; Interior flare nut is entrenched in the groove of collet body 2, when rotating procapsid 4, three pinch 1 scalable moving, one side of the back face 203 of collet body 2 has the through hole 202 that is interlinked to the outside in, the square hole of lockplate 6 is sleeved on 203 external diameters of hole, inboard, square hole lower end is entrenched in the through hole 202, and have part to expose in hole 203, be fitted with spring 7 in the middle of lockplate square hole upper end is inboard, when button 601 is pressed, be inlaid in lockplate 6 through hole 202 in and on endoporus 203 walls, can reveal and can flood with the groove fastening of drill gun main shaft or separate; Collet body 2 rear orifices 203 end faces have " ten " word breach 201, and driven rotary can match with " ten " word breach on the drill gun main shaft; Back casing 5 ring bodies one side has side opening 501, and lockplate 6 is inlaid in the side opening 501 and has button 601 to expose outer surface at back casing 5.
