317, eliminate the gap between the hanging ring adjusting screw rod 312 and mounting groove 311.Due on the hanging ring adjusting screw rod 312
316 holding tank of hanging ring is coherent spiral shape arc groove, therefore after lifting utensil is sling entire tongs by hanging ring 316, into
When row balance adjustment, it can directly rotate the hanging ring adjusting screw rod 312 and the position of hanging ring 316 is adjusted, without repeatedly
Entire tongs is lifted by crane, the time of adjustment is greatly saved；And once regulated, it can pass through adjusting nut 317
The position is locked, is retained, subsequent use is facilitated.
Further, in the hanging ring adjusting screw rod 312 and the 311 side wall contact surface of mounting groove and the adjusting spiral shell
Mother 317 and the 311 side wall contact surface of mounting groove, are coarse rubbing surface 319, are realized by the frictional force of two contact surfaces
It is locking.
Further, spanner operation portion is equipped on the hanging ring adjusting screw rod 312, conveniently by spanner come to hanging ring tune
The rotation of section screw rod 312 is operated, and when also conveniently tightening the adjusting nut 317, is preferably locked.In general, this is pulled
Hand operation portion can be set on the body of rod of hanging ring adjusting screw rod 312 and 311 side wall of mounting groove contact side, and spanner operation portion can
To be designed to square, it is also possible to hexagon, as long as convenient wrench blocks, is operated, thus it is not enterprising in schematic diagram
Row is shown.
The preferred embodiment created to the utility model above is illustrated, but the utility model is created not
It is only limitted to the embodiment, those skilled in the art go back under the premise of without prejudice to the utility model creative spirit
Various equivalent variation or replacement can be made, these equivalent modifications or replacement are all contained in the claim of this application and are limited
In the range of.
