At this time, the lower clamping plate 22 is rotated so that the lower clamping plate 22 and the upper clamping plate 21 are offset from each other, and the offset angle is generally about 50 °, so that the offset lower clamping plate 22 cannot interfere with the electrode copper rod 1. Then wholly remove the frock, through the clamping part 23 of punch holder 21 for the frock is unsettled to realize preliminary hanging. After hanging, the labor force can be relieved, and the weight of the whole tool is not required to be borne.
Second,: as shown in fig. 5 and 6, the lower clamp plate 22 is pulled downward, the spring 5 is compressed so that the lower clamp plate 22 and the upper clamp plate 21 have a certain gap, and then the lower clamp plate 22 is rotated so that the lower clamp plate 22 and the upper clamp plate 21 are restored to be aligned, and thus the alignment installation of the upper clamp plate 21 and the lower clamp plate 22 can be completed.
Third,: as shown in fig. 7, the lock nut 24 is screwed until the bottom end of the lower clamping plate 22 is tightly attached to the upper end surface of the rod frame 31, thereby completing the locking, and the spring 5 always provides elastic support, so that even if the lock nut 24 is loosened to some extent later, the upper clamping plate 21 and the lower clamping plate 22 can be connected stably and reliably all the time through the compensation of the spring 5.
The design of this kind of structure can allow whole frock to hang on electrode bar copper 1 through punch holder 21 earlier, then carries out fixed operation, promptly in the operation of second step and third step need not go through the manpower and support the weight of frock, labour saving and time saving.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
