Specific embodiment
As can be seen that a kind of closefisted drill chuck with lock of releasable deformation force from Fig. 1, Fig. 6, Fig. 5 comprising drill body
02, clamping jaw 03, screw 06, nut sleeve 07, bearing 05, bearing gasket 04, protheca 09 and rear enclosure 01 etc..There are three on drill body 02
The screw thread of inclined hole, screw thread and screw 06 inside of the clamping jaw 03 in inclined hole by side engages movement, and nut sleeve 07 is interference fitted
On screw, protheca and nut sleeve cooperation, protheca rotation drive nut sleeve rotation, and nut sleeve drives screw rotation, and screw drives
Clamping jaw is mobile.The 01 front end outer circle of drill body has unidirectional ratchet, and elastic slice 08 is housed on nut sleeve 07, has one on elastic slice 08
There are a pawl 084, protheca in positioning protrusion 081 and a lock projection 082 and an imposed deformation position 083, lock projection side
Have to unclamp elastic slice groove 091 and lock elastic slice positioning groove 096 inside 09 and be matched with the protrusion on elastic slice.On protheca 09
It is additionally provided with locking elastic slice protrusion 094.07 front end of nut sleeve is equipped with driving claw or driving groove 071, goes back in nut sleeve circumferential wall
If there are two symmetrical driving mouth 074, driving mouth 074 is corresponding with the protrusion on elastic slice.Above-mentioned composed structure and specific connection
Relationship and use process are identical as the hand-tight drill chuck with locking function of US5765839A, belong to the prior art, repeat no more.
The invention has the characteristics that the centre of two driving mouths 074 on the nut sleeve 07 is equipped with a release force and opens
Mouthful 072,07 upper open end outer circle position of nut sleeve is equipped with one or two elastic bumps 73, and the elastic bumps 73 are in screw
It puts on and is located above or below corresponding driving mouth 74；As shown in Fig. 4 or Fig. 9.
The corresponding position of the protheca 09 is equipped with locking positioning groove 093 and unclamps positioning groove 092.Such as Fig. 2, figure
3 or Fig. 7, Fig. 8 shown in.
Protheca is different with the assembly grafting of nut sleeve in described two schemes, and principle is the same.Correspondingly, nut sleeve front end
It is equipped with driving claw 071 or driving groove 071.Driving claw 071 is the protrusion stretched out, and driving groove is a kind of 071 groove knot
Structure.
The present invention is in use, protheca 09 drives nut sleeve 07 and elastic slice 08 to rotate together, the positioning protrusion of elastic slice 08
081 and lock projection in 082 be inserted on nut sleeve 07 two symmetrical driving mouths 074, the convex of elastic slice 08
It rises 081 in the release elastic slice positioning groove 095 of protheca 09, the release of the lock projection 082 of elastic slice 08 in protheca 09
In elastic slice groove 091, the elastic bumps 073 of nut sleeve 07 are in the release positioning groove 092 of protheca 09, on elastic slice 08
Imposed deformation position 083 nut sleeve 07 release force opening 072 in, when clamping drilling tool, protheca 09 is continued to rotate,
When rotatory force increases, greater than the elastic force of the elastic bumps 073 on the elastic force and nut sleeve 07 of the positioning protrusion 081 of elastic slice 08
When, protheca 09 rotates, and nut sleeve 07 and elastic slice 08 do not rotate, pine of the positioning protrusion 081 on elastic slice 08 from protheca 09
It opens and is moved in elastic slice positioning groove 095 in locking elastic slice positioning groove 096, the lock projection 082 of elastic slice 08 is from protheca
09 release elastic slice groove 091 is moved to raised 094 position of locking elastic slice of protheca 09,084 quilt of pawl of elastic slice 08
It is pressed into the ratchet 021 on drill body 02, in the process, 08 stress deformation of elastic slice, the imposed deformation position on elastic slice 08
083 is moved outwards in the release force opening 072 of nut sleeve 07, improves the stress condition of elastic slice 08.On nut sleeve 07
Elastic bumps 073 are moved to locking positioning groove 093 from the release positioning groove 092 of protheca 09, if rotatory force is sufficiently large,
Protheca 09 drives the driving claw of nut sleeve 07 or driving groove 071 to continue to rotate, and nut sleeve 07 and elastic slice 08 are followed together
Rotation, pawl 084 can slide on another ratchet 021 from a ratchet, and until 09 turn of protheca motionless, tool is pressed from both sides
Tightly.When back off tool, 09 opposite direction of protheca is rotated, and the pawl 084 on elastic slice 08 is stuck on ratchet 021, elastic slice 08 and silk
Mother set 07 is motionless, and protheca 09 needs first to overcome the elasticity on the elastic force and nut sleeve 07 of the positioning protrusion 081 on elastic slice 08
Protrusion 073, this just increases unlocking torque than the prior art, and the elastic force of the elastic bumps 073 on nut sleeve 07 influences
The size of unlocking torque, protheca 09 compress the elastic bumps 073 on positioning protrusion 081 and nut sleeve 07 on elastic slice 08,
The elastic bumps 073 of nut sleeve 07 are moved to from the locking positioning groove 093 of protheca 09 unclamps positioning groove 092, elastic slice
The release elastic slice positioning that 08 positioning protrusion 081 is moved to protheca 09 from the locking elastic slice positioning groove 096 of protheca 09 is recessed
In slot 095, the lock projection 082 of elastic slice 08 is moved to the release of protheca 09 from the locking elastic slice protrusion 094 of protheca 09
In elastic slice groove 091, the pawl 084 on elastic slice 08 is popped into position by elasticity, and the ratchet 021 being detached from drill body 02 reaches
It uncages purpose.
By above-mentioned improvement, the intermediate of two driving mouths 074 on nut sleeve 07 increases a release force and opens the present invention
Mouth 072, release of the purpose for the elastic slice 08 during locking by the oppressive force of protheca 09, reduces the part of elastic slice 08
Imposed deformation increases the service life of elastic slice 08；Outside any one open end side of two open ends of nut sleeve 07
Circle position increases one or more elastic bumps 073, while increasing locking positioning at the corresponding position of corresponding protheca 09
Groove 093 and release positioning groove 092, this structure play increase anti-loose effect in product locking process, improve the use of product
Performance.
