[0038] Working principle:

[0039] First, place the pick to be clamped into the inner end of the clamping rod 12, and then turn on the electric telescopic rod 9 to retract the rod body so as to drive the movable frame 10 to move inward. When the movable frame 10 slides, the sliding frame 14 will slide at the end of the movable frame 10.

The tooth block 20 at the end of the rotating disk 3 and the internal limit block 23 of the outer frame 2 form an engaging structure under the action of the spring 22, which can effectively position the rotating disk 3 after rotation.

[0042] The pick rotating clamping tool of the utility model uses a rotatable rotating disk to adjust the plane angle of the upper clamping structure, and cooperates with the engagement of the limit blocks at the four corners of the outer frame to position the rotating disk after rotation. At the same time, the clamped pick can be rotated by cooperating with the driving motor at the end of the first side plate and the connecting frame, so as to uniformly overheat the pick;
