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, comprising: working head 32 and the swinging axle 28 for driving working head 32 to swing.As shown in Figure 3 and Figure 4.
Be provided with two mutual involutory inner clip slide blocks 26 in the axis hole of described swinging axle 28, described inner clip slide block 26 fit beneath has fastening spring 27, and the spacing back-up ring 25 in hole is equipped with in top.
Described swinging axle 28 laterally offers four long oval holes, and on described inner clip slide block 26, corresponding long oval hole offers eight oblique oval holes, and four holding pins 30 respectively first through long oval hole, then pass oblique oval hole.
The both sides of described inner clip slide block 26 are also provided with spacing alignment pin 29.Described swinging axle 28 is also equipped with bearing 24 and axle sleeve 23.
Be provided with terminal pad 31 and Working-Clip seat 33 below described swinging axle 28, described working head 32 is located between terminal pad 31 and Working-Clip seat 33, and described Working-Clip seat 33, through working head 32 and terminal pad 31, extends between four holding pins 30 in swinging axle 28.
Assembled by 2 pieces of identical inner clip slide blocks 26 one overall, load together with fastening spring 27 in swinging axle 28 hole, by four holding pins 30 through the long oval hole of swinging axle 28 and the oblique oval hole of inner clip slide block 26.In the long oval hole of transverse direction that four holding pins 30 are contained in swinging axle 28, holding pin 30 only has transverse shifting may.Simultaneously four holding pins 30 are also through in the oblique oval hole of inner clip slide block 26, inner clip slide block 26 alignment pin 29 spacing under, can only move up and down, namely the oblique oval pore area of inner clip slide block 26 moves holding pin 30 moving laterally in swinging axle 28 transverse waist circular hole.
As shown in Fig. 1,2 and 5, the top of described inner clip slide block 26 is connected with one end of last item 9, and 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, and withstands inner clip slide block 26 and moves down, and drives holding pin 30 laterally outwards mobile, reserves the space that Working-Clip seat 33 enters between holding pin 30.
When spanner 1 rotates backward and turns back, last item 9 moves up, and owing to not having last item 9 pressure, inner clip slide block 26 is used at the elastic force of fastening spring 27 and moved up, thus drives holding pin 30 laterally inwardly to move, and realizes Quick-clamped Working-Clip seat 33.Under the elastic force effect of fastening spring 27, holding pin 30 clamps Working-Clip seat 33 firmly, thus realizes working head 32 and be securely fixed between terminal pad 31 and Working-Clip seat 33.
Described terminal pad 31 is one-body molded with swinging axle 28 or be fixedly connected with.The preferred structure of the utility model is fixedly mounted on swinging axle 28 by terminal pad 31.
Swinging axle 28 is driven by motor, the swinging axle 28 driven by motor and the working head 32 be arranged on below swinging axle 28 and terminal pad 31, Working-Clip seat 33 stretches in swinging axle 28 hole through after working head 32, thus working head 32 is fixed on swinging axle 28 and terminal pad 31, and move under the drive of swinging axle 28.
Drives structure is provided with between described motor and swinging axle 28, described drives structure comprises the eccentric shaft 15 being located at motor output end and the shift fork 22 be assemblied on swinging axle 28, 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 28 do rotational oscillating motion.
Figure 1 shows that 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 inner clip slide block 26 overcomes fastening spring 27 moves down, and 4 holding pins 30 are under inner clip slide block 26 has oblique oval hole and the constraint of swinging axle 28 transverse holes, holding pin 30 outwards movement, between reserve the space passed for Working-Clip seat 33.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 28 inside.
Figure 2 shows that 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 not having the pressure of last item 9, inner clip slide block 26 moves up under the elastic force effect of fastening spring 27, and four holding pins 30 are under inner clip slide block 26 has oblique oval hole and the constraint of swinging axle 28 transverse holes, holding pin 30 moves inward, Quick-clamped Working-Clip seat 33.Now, under the elastic force of fastening spring 27,4 holding pins 30 can clamp Working-Clip seat 33 firmly, when working head 32 works, there will not be the sliding phenomenon of Working-Clip seat 33 pine.
Working head 32 is fastened on swinging axle 28 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 1 grade.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 hand-hold power tool, 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.
