Fig. 2 is front section view of the present invention.
In figure: 1: jaw block; 2: lever; 3: roller; 4: overcoat; 5: alignment pin; 6: screw rod; 7: feeding cone.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, the clip claw assembly, the feeding cone 7 that the present invention includes overcoat 4 and be arranged on overcoat 4; Overcoat 4 front portion is provided with multiple clip claw assembly, and multiple clip claw assembly is contained in the anterior outer wall of overcoat 4 along overcoat 4 ambient separation is uniform, forms bare terminal end.
Clip claw assembly comprises jaw block 1, lever 2 and roller 3, jaw block 1, lever 2 and roller 3 become a clip claw assembly by pinned connection, in the middle part of lever 2 by hinge on the pole of the anterior outer wall of overcoat 4, jaw block 1 is hinged on the front end of lever 2, in the middle part of lever 2, hinge place is provided with for keeping roller 3 to contact torsion spring all the time with the conical surface of feeding cone 7, the bearing pin and the torsion spring that connect jaw block 1 and lever 2 make jaw block 1 can swing around lever 2 end, and limit jaw block 1 and can only necessarily freely swing in pivot angle.
The rear end of lever 2 is provided with roller 3, the front end of lever 2 is provided with jaw block 1, and feeding cone 7 is equipped with in inside, overcoat 4 rear end, and feeding cone 7 front portion is frustum cone structure, small end is towards clip claw assembly, and the roller 3 of clip claw assembly rolls with the conical surface outer wall of feeding cone 7 through the fluting of overcoat 4 wall and is connected.
As shown in Figure 2, feeding cone 7 is enclosed within overcoat 4 by alignment pin 5, feeding cone 7 sidewall is provided with bar-shaped trough vertically, the through hole that alignment pin 5 passes overcoat 4 is inserted into the radial rotary of spacing feeding cone 7 in bar-shaped trough, feeding cone 7 is moved vertically, ensure that feeding cone 7 can move but can not rotate in overcoat 4.
On the one hand, the present invention is connected with screw rod 6 by clip claw assembly rear end, and screw rod 6 is coordinated by the screw thread pair of self-locking with the endoporus of feeding cone 7, makes to apply to rotate peripheral force, form axial advance power, increase clamping force by screw structure.Another fermentation, lever of the present invention is fold-line-shaped, formation obtuse angle, front-end and back-end, the long bar be less than on rear side of bearing pin of the bar on front side of lever bearing pin is long, makes feeding cone 7 power be applied on lever 2 rear end roller 3 be delivered to lever 2 front end to increase clamping force further.
Specific works process of the present invention is as follows:
As shown in Figure 2; the inclined-plane of feeding cone 7 is applied on jaw block 1 by roller 3 and lever 2; moved axially in overcoat 4 by feeding cone 7 and promote lever 2 and to rotate around bearing pin and then to drive jaw block 1 to move; three jaw blocks 1 are made to close up or open; simultaneously by leverage, clamping force is amplified.
As shown in Figure 1, screw rod 6 rotates and feeding cone 7 is moved in overcoat 4, is fixed by screw rod 6, drives moving axially of feeding cone 7 by rotary sleeve 4 in concrete enforcement.Drill handle part is extend between three jaw blocks 1, then rotary sleeve 4, three jaw blocks 1 just can be made to close up and clamp; On the contrary, reversely rotate overcoat 4, just can unclamp jaw block 1, take out drill bit.
Thus the relatively rotating of overcoat 4 and screw rod 6 can control jaw block 1 and open and clamp, and by leverage, clamping force is amplified.The screw thread pair formed due to screw rod 6 and feeding cone 7 has auto-lock function, makes drill jig of the present invention have auto-lock function.
Present invention achieves amplification clamping force, drill bit can be clamped fast, clamping operation very convenient, there is self-locking performance, device simple for structure, processing cost is low.
