[0010] Further configuration: the rack is slidably connected to the base.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] Through the setting of the pressing component and the feeding component of the crimping mechanism, during the pressing process, the mounting plate and the rack of the pressing component are engaged with the gear to drive the rotating rod to rotate, so that the rotating rod pushes the placement seat to move to the lower side of the die. After moving into place, the rack enters the toothless stage, and the mounting plate continues to move downward, so that the die applies pressure to the wiring harness terminal. Then the cylinder contracts, first driving the die and the rack to move upward, and then the rack engages with the gear to rotate, so that the gear drives the rotating rod to reverse and push the placement seat forward, so that the whole process can be realized by the cylinder to move up and down and forward and backward, thereby improving the simplicity of operation and facilitating the picking and placing of the wiring harness.
