[0022] Specifically, the power device 4 can be a cylinder, which is arranged on the base plate 1, and the telescopic end of the cylinder is connected to the clamping arm 2. When the piston of the cylinder is extended, the clamping arm 2 opens, the distance between the two clamping plates 3 is shortened, and the clamping claw clamps the alloy ingot; when the piston of the cylinder is retracted, the clamping arm 2 is retracted, the distance between the two clamping plates 3 is increased, and the clamping claw releases the alloy ingot.

[0023] The bottom plate 1 is rectangular, and two protruding connecting parts 11 are provided at both ends of the bottom plate 1. The connecting parts 11 are provided with through holes, and a connecting pin is rotated in the through holes. A clamping arm 2 is fixed on the pin shaft, and the clamping arm 2 is rotatably connected to the connecting part 11 through a pin.

[0024] like Figure 2 As shown, the clamping plate 3 is in an “L” shape, the long side of the clamping plate 3 is fixed on the inner side of the clamping arm 2 , and the jaw tooth plate 5 is fixed on the inner side of the short side of the clamping plate 3 .

The clamping surface of the jaw tooth plate 5 is at an angle with the bottom surface, and the angle is between 68° and 72°. Preferably, the clamping surface of the jaw tooth plate 5 is at an angle of 70.44° with the bottom surface.

[0026] The clamping surface of the jaw tooth plate 5 is provided with an anti-slip groove 51.

In this process, since the clamping surface of the jaw tooth plate 5 is at an angle to the bottom surface, and the anti-slip groove 51 is provided on the clamping surface of the jaw tooth plate 5, the friction between the clamping surface of the jaw tooth plate 5 and the alloy ingot is increased, making the alloy ingot not easy to slip.
