Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in figs. 1-12, a kind of reducing sleeve, it comprises handle 7, handle 7 matches with pedestal 1 transmitting torque, pedestal 1 inside is provided with bevel gear wheel 2, and bevel gear wheel 2 forms meshed transmission gear with three bevel pinions 3 simultaneously, and three mobile claws 4 form screw-driven with bevel pinion 3 respectively and are connected, mobile claw 4 and base plate 5 are formed and are slidably matched and are arranged on the inside of pedestal 1 by base plate 5, and base plate 5 is fixed on the bottom of pedestal 1 by screw 6.
As Fig. 5, the head of described handle 7 is installed with square toes 701, and afterbody is processed with annular knurl 702.Can to be matched with the square hole 101 of pedestal 1 head transmitting torque by square toes 701, can conveniently be pulled handle 7 by annular knurl 702.
As Fig. 6, the top of described pedestal 1 is processed with square hole 101 and matches with the square toes 701 of handle 7.Adjustment member can be installed therein by pedestal 1 thus realize the adjustment of claw 401 spacing.
As Fig. 7, the upper end of described bevel gear wheel 2 is provided with knob 201, and lower end is provided with the auger flank of tooth 202.By the rotation rotarily driving the auger flank of tooth 202 of knob 201, and then drive the rotation of the bevel pinion 3 be engaged with, thus realize the adjustment of spacing between mobile claw 4, to adapt to different bolts.
