Detailed description of the invention
From Fig. 1, Fig. 6, Fig. 5, can find out, a kind of closefisted drill chuck with lock that discharges deformation force, it comprises drill body 02, jaw 03, screw 06, nut sleeve 07, bearing 05, bearing gasket 04, protheca 09 and rear cover 01 etc. On drill body 02, have three inclined holes, jaw 03 moves by the screw thread of a side and the screw-threaded engagement of screw 06 inner side in inclined hole, and nut sleeve 07 is interference fitted on screw, protheca and nut sleeve coordinate, protheca rotates and drives nut sleeve to rotate, and nut sleeve drives screw to rotate, and screw drives jaw to move. Described drill body 01 front end cylindrical has unidirectional ratchet 021, shell fragment 08 is housed on nut sleeve 07, on shell fragment 08, there are a positioning convex 081 and lock projection 082 and an imposed deformation position 083, lock projection side has a sour jujube, 084, protheca 09 inside has unclamps shell fragment groove 091 and locks shell fragment detent 096 and match with the projection on shell fragment. On protheca 09, be also provided with locking shell fragment projection 095. Nut sleeve 07 front end is provided with driving claw or drives groove 071, is also provided with two symmetrical driving mouths 074 in nut sleeve circle wall, drives mouth 074 corresponding with the projection on shell fragment. Above-mentioned composition structure and concrete annexation are identical with the hand-tight drill chuck with locking function of US5765839A with use procedure, belong to prior art, repeat no more.
Feature of the present utility model is: two on described nut sleeve 07 drive the centre of mouth 074 to be provided with a release force opening 072, nut sleeve 07 upper open end cylindrical position is provided with one or two elastic bumps 73, and described elastic bumps 73 is positioned at above or below corresponding driving mouth 74 on nut sleeve; As shown in Fig. 4 or Fig. 9.
The corresponding position of described protheca 09 is provided with locking positioning groove 093 and unclamps detent 092. As shown in Fig. 2, Fig. 3 or Fig. 7, Fig. 8.
In described two schemes the assembling of protheca and nut sleeve peg graft different, principle is the same. Accordingly, nut sleeve front end is provided with driving claw 071 or drives groove 071. Driving claw 071 is the projection of stretching out, and driving groove is 071 1 kinds of groove structures.
When the utility model uses, protheca 09 drives nut sleeve 07 to rotate together with shell fragment 08, the positioning convex 081 of shell fragment 08 and lock projection are in 082 two symmetrical driving mouths 074 that are inserted on nut sleeve 07, the positioning convex 081 of shell fragment 08 unclamps in shell fragment detent 095 protheca 09, the lock projection 082 of shell fragment 08 is unclamped in shell fragment groove 091 protheca 09, the elastic bumps 073 of nut sleeve 07 unclamps in detent 092 protheca 09, imposed deformation position 083 on shell fragment 08 is in the release force opening 072 of nut sleeve 07, in the time clamping drilling tool, protheca 09 is rotated further, when rotatory force increases, while being greater than the elastic force of the elastic bumps 073 on elastic force and the nut sleeve 07 of positioning convex 081 of shell fragment 08, protheca 09 rotates, nut sleeve 07 and shell fragment 08 do not rotate, positioning convex 081 on shell fragment 08 moves in locking shell fragment detent 096 from unclamping in shell fragment detent 095 of protheca 09, the lock projection 082 of shell fragment 08 is from locking shell fragment projection 094 position of unclamping shell fragment groove 091 and move to protheca 09 of protheca 09, the ratchet 084 of shell fragment 08 is pressed in the ratchet 021 on drill body 02, in this process, shell fragment 08 stress deformation, imposed deformation position 083 on shell fragment 08 is outwards moved at release force opening 072 internal diameter of nut sleeve 07, improve the stressing conditions of shell fragment 08. elastic bumps 073 on nut sleeve 07 moves to locking positioning groove 093 from the detent 092 that unclamps of protheca 09, if rotatory force is enough large, protheca 09 drives the driving claw of nut sleeve 07 or drives groove 071 to be rotated further, nut sleeve 07 rotates together with following with shell fragment 08, ratchet 084 can slide into another ratchet 021 from a ratchet, until protheca 09 turns motionless, instrument is clamped. when back off tool, protheca 09 counter-rotation, ratchet 084 on shell fragment 08 is stuck on ratchet 021, shell fragment 08 and nut sleeve 07 are motionless, protheca 09 need to first overcome the elastic bumps 073 on elastic force and the nut sleeve 07 of the positioning convex 081 on shell fragment 08, this has just increased than prior art the moment of unblanking, the elastic force of the elastic bumps 073 on nut sleeve 07 affects the size of the moment of unblanking, protheca 09 compresses the elastic bumps 073 on positioning convex 081 and the nut sleeve 07 on shell fragment 08, the elastic bumps 073 of nut sleeve 07 moves to and unclamps detent 092 from the locking positioning groove 093 of protheca 09, the positioning convex 081 of shell fragment 08 moves to unclamping in shell fragment detent 095 of protheca 09 from the locking shell fragment detent 096 of protheca 09, the lock projection 082 of shell fragment 08 moves to unclamping in shell fragment groove 091 of protheca 09 from the locking shell fragment projection 094 of protheca 09, ratchet 084 on shell fragment 08 pops into position by elasticity, depart from the ratchet 021 on drill body 02, reach the object of uncaging.
The utility model is by above-mentioned improvement, in the middle of two driving mouths 074 on nut sleeve 07, increase a release force opening 072, object is subject to the release of the oppressive force of protheca 09 for the shell fragment 08 of locking process, reduce the P-Coercive distortion of shell fragment 08, increases the service life of shell fragment 08; Any one cylindrical position, openend side at two openends of nut sleeve 07 increases one or more elastic bumps 073, increase locking positioning groove 093 and unclamp detent 092 at the corresponding position of corresponding protheca 09 simultaneously, this structure plays and increases locking effect in product locking process, improves the serviceability of product.
