[0002] The finished product of emulsion explosive needs to be loaded after being boxed, and a handling mechanical arm is generally used for loading during loading. The clamp on the existing handling mechanical arm cannot position the object, so that the object position deviates when the clamp directly clamps the object, which easily causes the object to fall during clamping, thereby causing damage to the object.
