Label among the figure is: 1. drill body, 2. back cover, 3. jump ring, 4. gear, 5. bearing, 6. screw, 7. nut sleeve, 8. protheca, 8-1. groove, 9. spring leaf, 10. jaw.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of band of the utility model rings manually fastened drill chuck, includes drill body 1, back cover 2, screw 6, jaw 10, nut sleeve 7, protheca 8, bearing 5, jump ring 3.Nut sleeve 7 is fixedlyed connected with screw 6, protheca 8 is connected with nut sleeve 7 keys, back cover 2 is fixedlyed connected with drill body 1, there are screwed hole or taper hole in the drill body rear portion, three jaws 10 are installed in respectively in three five equilibrium inclined holes of drill body 1, screw 6 is installed in the screw groove of drill body 1, and screw 6 forms thread transmission with the screw thread of jaw 10, drives that jaw 10 is protruding to come clamping tool.The pass of said structure and coupled parts is a prior art, and this does not describe in detail.
Characteristics of the present utility model are: be provided with a gear that can rotate on drill body 4 between drill body 1 end face and the bearing 5, gear 4 and drill body 1 matched in clearance, the position of protheca 8 inboard corresponding gear is provided with groove 8-1, spring leaf 9 is installed among the groove 8-1, spring leaf 9 contacts with gear 4, and relatively rotates with gear under protheca drives, and spring leaf produces strain, with gear 4 bumps, send " click click " sound.
The said gear 4 of the utility model can be provided with symmetrical double wedge, and said spring leaf 9 can be " V " font elasticity profile, and " V " word slope angle 9-4 contacts with gear, and consistent with the double wedge shape of gear 4.As shown in Figure 2.The position of protheca 8 inboard corresponding gear is provided with the groove 8-1 of two symmetries, and " V " font flexure strip is installed in wherein, can rotate along with the rotation of protheca 8.Its course of work is: when clamping tool, protheca 8 drives screw 6 rotations, screw 6 and jaw 10 are formed to relatively rotate, drive that jaw 10 is protruding to come clamping tool, the spring leaf 9 of while in two grooves of protheca 8 driving gear 4 and together rotating, when jaw 10 is clamped instrument, gear 4 is subjected to axial compressive force, produce frictional force between the end face of gear 4 and drill body 1 contact, gear 4 stops operating under the effect of frictional force, for clamping tool continues rotation protheca 8, spring leaf 9 relatively rotates with 4 formation of sounding gear under the driving of protheca 8, spring leaf 9 produces strain repeatedly, and clashes into sounding gear 4, sends " click click " sound.When back off tool, protheca 8 drives screw 6 and spring leaf 9 reverse rotations, this moment, gear 4 maintained static under the effect of frictional force, spring leaf 9 clashes into generation gear 4 repeatedly and sends " click click " sound, continue the rotation protheca, axial compressive force between gear 4 and the drill body 1 and the frictional force between the end face reduce gradually until disappearance, and gear 4 together rotates with spring leaf 9 under the elastic force effect of spring leaf 9 like this.Screw 6 drives jaw 10 and inwardly shrinks back off tool.
The said gear 4 of the utility model also can be provided with unidirectional ratchet, as shown in Figure 4.Spring leaf also can in the middle of the camber sheet of band positioning convex 9-1, an end is elastic pawl 9-2, an end is balance ratchet 9-3, contact with gear respectively, the unidirectional ratchet engagement of elastic pawl 9-2 and gear 4, balance ratchet 9-3 also is provided with " V " shape slope angle, like this, it can conveniently slide on gear 4.As shown in Figure 3.The position of protheca 8 inboard corresponding gear is provided with the groove 8-1 of symmetry, and the band positioning convex 9-1 in the middle of the spring leaf 9 is installed in wherein, can rotate along with the rotation of protheca 8.For the needs of back off tool operation, spring leaf 9 and protheca groove 8-1 will have certain interval, that is to say the width of the width of positioning convex 9-1 less than groove 8-1.Like this, when clamping tool, protheca 8 drives screw 6 rotations, screw 6 and jaw 10 are formed to relatively rotate, drive that jaw 10 is protruding to come clamping tool, the spring leaf 9 of while in the groove of protheca 8 driving gear 4 and together rotating, when jaw 10 is clamped instrument, gear 4 is subjected to axial compressive force, produce frictional force between the end face that itself and drill body 1 contact, gear 4 stops operating under the effect of frictional force, and for clamping tool continues rotation protheca 8, spring leaf 9 relatively rotates with gear 4 formation under the driving of protheca 8, elastic pawl 9-2 on the spring leaf 9 is unidirectional on gear 4 to slip over several teeth, produce strain repeatedly, and clash into, send " click click " sound with gear 4.Balance ratchet 9-3 is used for the strength of balance sounding elastic pawl 9-2.When back off tool, protheca 8 drives screw 6 reverse rotations, and this moment, gear 4 maintained static under the effect of frictional force, spring leaf 9 also maintains static, because spring leaf 9 and protheca 8 have certain interval, continue the rotation protheca, spring leaf 9 can along the circumferential direction rotate to an angle in groove.Like this, axial compressive force between gear 4 and the drill body 1 and the frictional force between the end face reduce gradually until disappearance, and gear 4 together rotates with spring leaf 9 under the elastic force effect of the elastic claw 9-2 on the spring leaf 9.Inwardly shrink back off tool until jaw 10.
