Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment comprises:
A fast fixture for hand-hold power tool, working head 32 and the swinging axle 30 for driving working head 32 to swing.
As shown in Figure 3 and Figure 4, the inner concentric of axis hole of described swinging axle 30 is equipped with steel ball cutting ferrule, tiltedly guide pin bushing 26 and fastening spring 29,2 steel balls 28 are loaded in the transverse waist circular hole of described steel ball cutting ferrule, oblique guide pin bushing 26 covers at and is equipped with outside the steel ball cutting ferrule 27 of steel ball 28, and fastening spring 29 is located at below steel ball cutting ferrule 27.
Described swinging axle 30 fit beneath has terminal pad 31 and Working-Clip seat 33, described terminal pad 31 is fixedly connected with swinging axle 30, described Working-Clip seat 33 extends through terminal pad 31 two steel balls 28 in swinging axle 30, and described working head 32 is located between terminal pad 31 and Working-Clip seat 33.
Wherein, the inclined-plane that the inner surface of described oblique guide pin bushing 26 is up-narrow and down-wide.Spacing hole back-up ring 25 is provided with above described oblique guide pin bushing 26.Described swinging axle 30 is also equipped with bearing 24 and axle sleeve 23.
Steel ball 28 is loaded in steel ball cutting ferrule 27 transverse waist circular hole, outer mask tiltedly guide pin bushing 26 and is loaded together with fastening spring 29 in swinging axle 30 hole, when steel ball cutting ferrule 27 moves up and down with steel ball 28, steel ball 28 is along under the up-narrow and down-wide ramp effect of oblique guide pin bushing 26 inner surface, and while moving up and down, lateral attitude also changes simultaneously, namely when steel ball cutting ferrule 27 is moved, steel ball 28 can produce lateral displacement, outwards moves and loosens, move inward clamping.
Described Working-Clip seat 33 is provided with clamping position, concaved circular cambered surface in described clamping position is corresponding with steel ball 28.
As shown in Figure 1, Figure 2 with shown in Fig. 5, be connected above described steel ball cutting ferrule 27 with one end of last item 9, the axle body of described last item 9 is equipped with spring, and the other end of last item 9 is connected with the spanner 1 moved up and down for controlling last item 9.
When spanner 1 rotates forward and pulls open, last item 9 moves down, withstand steel ball cutting ferrule 27 to overcome fastening spring 29 elastic force and move down, when steel ball cutting ferrule 27 moves down, namely steel ball cutting ferrule 27 increases with the space of oblique guide pin bushing 26, gap between 2 steel balls 28 becomes large, can hold the space that Working-Clip seat 33 enters.
When spanner 1 rotates backward and turns back, last item 9 moves up, owing to there is no the pressure of last item 9, steel ball cutting ferrule 27 is used at the elastic force of fastening spring 29 and is moved up, thus drive steel ball 28 to move up, while steel ball 28 moves up, in the inclined-plane acting in conjunction of oblique guide pin bushing 26, 2 steel balls 28 upwards move inwards, clamp the interior concaved circular cambered surface part of Working-Clip seat 33, under the elastic force effect of fastening spring 29, steel ball cutting ferrule 27 has the trend up walked always, therefore 2 steel balls 28 are under oblique guide pin bushing 26 acting in conjunction of fastening spring 29 steel ball cutting ferrule 27, steel ball 28 is upwards clamped Working-Clip seat 33 firmly, thus realize working head 32 and be securely fixed between terminal pad 31 and Working-Clip seat 33.
Swinging axle 30 is driven by motor, drives structure is provided with between described motor and swinging axle 30, described drives structure comprises the eccentric shaft 15 being located at motor output end and the shift fork 22 be assemblied on swinging axle 30, described eccentric shaft 15 is also equipped with ball bearing 16, and described shift fork 22 is connected with ball bearing 16.
During revolution, drive eccentric shaft 15 and ball bearing 16 to rotate, and then drive shift fork 22 to realize rotary oscillation, thus make swinging axle 30 do rotational oscillating motion.Wherein, swinging axle 30 end is provided with the larger terminal pad of diameter 31, terminal pad 31 is provided with the square hole passed for Working-Clip seat 33, terminal pad 31 and swinging axle 30 can be one-body molded, also can be fixedly mounted on swinging axle 30, in the utility model preferred embodiment, terminal pad 31 is fixedly mounted on swinging axle 30.
As shown in Figure 2, spanner 1 untie-sell that rotates rotates forward when pulling open, spanner 1 is when rotating, use at cam mechanism, last item 9 is moved down, under the pressure of last item 9, the elastic force that steel ball cutting ferrule 27 overcomes fastening spring 29 moves down, steel ball 28 moves down under steel ball cutting ferrule 27 drives simultaneously, because the inner surface of oblique guide pin bushing 26 is inclined-planes, steel ball cutting ferrule 27 and steel ball 28 move down, and namely between steel ball cutting ferrule 27 and oblique guide pin bushing 26, space becomes large gradually, namely reserves the space passed for Working-Clip seat 33 between steel ball 28.Now, working head 32 is arranged on below terminal pad 31, and Working-Clip seat 33, through working head 32, extend in the Quick-clamped structure of swinging axle 30 inside.
As shown in Figure 1, spanner 1 untie-sell that rotates rotates when turning back backward, spanner 1 is when rotary motion, under cam mechanism effect, last item 9 is moved up, owing to there is no the pressure of last item 9, steel ball cutting ferrule 27 moves up under the elastic force effect of fastening spring 29, steel ball cutting ferrule 27 drives steel ball 28 to move up together, 2 steel balls 28 inwardly clamp gradually along oblique guide pin bushing 26 inward hole slope simultaneously, 2 steel balls 28 have clamped the circular arc portion of Working-Clip seat 33, under the elastic force effect of fastening spring 29, steel ball cutting ferrule 27 has the trend up walked always, therefore 2 steel balls 28 are under oblique guide pin bushing 26 acting in conjunction of fastening spring 29 steel ball cutting ferrule 27, steel ball 28 is upwards clamped the interior concaved circular cambered surface of Working-Clip seat 33 firmly, thus realize working head 32 and be securely fixed between terminal pad 31 and Working-Clip seat 33.Realize Quick-clamped Working-Clip seat 33.
Working head 32 is fastened on swinging axle 30 by simple and reliable mode by the fast fixture of the utility model hand-hold power tool, and without the need to using the aid of such as spanner etc.Can have the clamping force that realization is stronger, even if such as by heavy duty situation, this clamping force is also enough to guarantee reliably and securely to make working head 32 clamp; The fast fixture compact conformation of this multifunctional saw, cost is low, can clamping quickly and efficiently.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
