[0002] Currently, when mold manufacturers replace molds, two workers are required to work together to push the mold from the fork to the mold rack, or to pull the mold from the mold rack to the fork. Since the mold is heavy (200-300Kg), this operation is laborious, time-consuming and unsafe for workers.

[0003] When transporting a heavy mold, a forklift is generally used to transport the heavy mold. However, the spacing between the forklift arms of the existing forklift is fixed, and the molds to be transported are of different sizes. When the mold is small, it is inconvenient for the two forklift arms with a fixed spacing to fork and transport the mold. When the mold is large, it is inconvenient for the two forklift arms with a fixed spacing to fork and stably transport the mold. In order to solve the above problems, a picking fixture is proposed in the present application. Utility Model Content
