When the pallet is transported to the designated workstation, the return spring resets and drives the second connecting rod to reset, thereby driving the first connecting rod to return. The rotating locking disk drives the locking block to flip and disengage from the locking groove to unlock the pallet. By setting up an automatic locking mechanism, automatic locking and unlocking can be achieved when taking and placing the pallet, so that the pallet can be accurately placed and quickly detached, thereby realizing stable and efficient switching of pallet tooling.
