The specific embodiment
See also Fig. 1, Fig. 2, embodiment of the present utility model comprises a hexagonal body of rod 1, one end of this body of rod 1 has a drive division 11, this body of rod 1 has one away from this drive division 11 and is connected section 12 to be connected with a switching portion 13, this linking section 12 is an angle with switching portion 13, in the present embodiment, this linking section 12 is to be 90 degree with switching portion 13.
The above-mentioned body of rod 1 is provided with an adjustment part 14 at these drive division 11 centers, these 14 centers, adjustment part have a cone tank 141 for a ccontaining circular cone 142 towards this linking section 12, and the notch radius of this cone tank 141 is greater than this bottom radius, and the circular cone 142 of this adjustment part 14 is provided with a resetting means 145 towards these cone tank 141 bottom land directions.In the present embodiment, this resetting means 145 is a screw rod 144 sheathed compression springs 146 that stretch through, and is screwed at the set screw 143 of bottom land with this cone tank 141.
Above-mentioned adjustment part 14 has the groove 15 that is provided with and matches with circular cone 142 peripheries at interval at these cone tank 141 peripheries towards this linking section 12, and in the present embodiment, each groove 15 is to be arranged on this body of rod 1 equidistributed plane.By moving of this circular cone 142, make the two side of each groove 15 expand outwardly distortion.
When workpiece or die nut in use for some time, as shown in Figures 3 and 4, constantly unscrewing or revolving in the process of lock, cause the containing hole at workpiece top to produce distortion, perhaps the corner wear of respectively holding of die nut is out of shape, even do not have the end angle or the plane of ending on any top, and make the workpiece can't rotary lock or unscrew and recess.At this moment, can adjust the adjustment part 14 of this die nut, earlier this drive division 11 is inserted in the containing hole at workpiece top, press down towards the workpiece direction again, circular cone 142 in this adjustment part 14 is moved towards the bottom land direction of this cone tank 141 because of being stressed, then can make the sidewall of each groove 15 expand outwardly distortion, and when these 14 tops, adjustment part are ended to the width that is fit to and the degree of depth, can manipulate.Behind end of operation, the drive division 11 of die nut can be loosened, utilize the elastic-restoring force of the compression spring 146 of this resetting means 145, with these circular cone 142 outside pushing tows, and make the sidewall of each groove 15 inwardly tighten recovery once again.Since die nut be expanded to respectively hold angle or plane Ke Ding stop the workpiece top containing hole respectively hold angle or plane, and can pull strained bolt or sleeve easily.
See also Fig. 5 and Fig. 6, it is second embodiment of the present utility model, this resetting means 145 is for being arranged on the magnet 147 that this circular cone 142 is inhaled towards the two-phase of an end of these cone tank 141 bottom land directions and this cone tank 14 2 bottom lands, and each groove 15 is to be arranged on the end angle that these body of rod 1 two relative adjacent planes are constituted.When workpiece can't rotary lock or unscrew and recess, also this drive division 11 can be inserted in the containing hole at workpiece top, press down towards the workpiece direction again, circular cone 142 in this adjustment part 14 is moved towards the bottom land direction of this cone tank 141 because of being stressed, then can make the sidewall of each groove 15 expand outwardly distortion, and when these 14 tops, adjustment part are ended to the width that is fit to and the degree of depth, can manipulate.Behind end of operation, the drive division 11 of die nut can be loosened, because inwardly tightening once again, the sidewall of each groove 15 restores, then circular cone 142 outer rims of this resetting means 145 will outwards move along this cone tank 141, and the magnet 147 that this two-phase is inhaled will make this circular cone 142 this cone tank 141 that can not drop.Since die nut be expanded to respectively hold angle or plane Ke Ding stop the workpiece top containing hole respectively hold angle or plane, and can pull strained bolt or sleeve easily.
In sum, structural improvement of the present utility model can reach the practical effect of pulling strained bolt or sleeve easily really.
