Description of drawings
Fig. 1 is the utility model clamp structure schematic diagram.
Among the figure: 1, base; 2, datum tooth holder; 3, datum tooth; 4, locking tooth; 5, bulb spacer pin; 6, spacer pin holder; 7, locking tooth holder; 8, ball screw; 9, lock-screw; 10, dial; 11, locking handwheel; 12, handwheel holder; 13, pressing plate; 14, sheet spring; 15, locking tooth fixed head.
The specific embodiment
As shown in Figure 1, these anchor clamps comprise base 1, datum tooth holder 2, datum tooth 3, locking tooth 4, bulb spacer pin 5, spacer pin holder 6, locking tooth holder 7.The bottom surface of datum tooth holder 2 and locking tooth holder 7 all is fixed on the base 1; A side of datum tooth holder 2 has a mounting groove, and datum tooth 3 is installed in this mounting groove, and its tooth portion protrudes from this mounting groove; A side of locking tooth holder 7 also has a mounting groove, and locking tooth 4 is installed in this mounting groove, and its tooth portion protrudes from this mounting groove.Spacer pin holder 6 is fixed on the base 1, and bulb spacer pin 5 is fixed on the spacer pin holder 6.
Locking tooth holder 7 is installed on the base 1 by locking tooth fixed head 15.Be installed in both connecting portions by two sheet springs 14 between locking tooth holder 7 and the locking tooth fixed head 15 and be connected, two pressing plates 13 are installed in the surface of one of sheets spring 14, fix by screw and locking tooth holder 7 and locking tooth fixed head 15 respectively.Fix by two screws between locking tooth fixed head 15 and the base 1, screw along with shown in the vertical direction of mounting groove have amount of movement.
In another side of locking tooth holder 7 ball screw 8, handwheel holder 12, locking handwheel 11, dial 10, lock-screw 9 are installed.Ball screw 8 is connected with locking handwheel 11, is installed in the both sides of handwheel holder 12 respectively, and dial 10 is installed in the handwheel outer ring.The axle of locking handwheel passes handwheel holder 12 and contacts with ball screw 8, and lock-screw is installed in the upper surface of handwheel holder 12, contacts with the axle of locking handwheel.
