[0025] The limiting mechanism 7 includes a limiting groove 71, a card slot 72, a locking block 73, a sliding rod 74, a card block 75 and an unlocking unit. The limiting groove 71 is horizontally arranged on the base 1, the card slot 72 is arranged on one side of the crimping plate 6, the locking block 73 is fixed on the crimping plate 6 and is located at one end of the card slot 72, the sliding rod 74 is slidably connected in the base 1, the card block 75 is fixed on the sliding rod 74, and the card block 75 abuts against the locking block 73, and the unlocking unit is arranged on the crimping plate 6.

[0026] It should be noted that, since the outer cavity and the crimping cavity of the existing heavy-duty crimping molds are mostly of an integrated design, during the crimping process, it is often necessary to replace different types of crimping cavities according to actual conditions and different standards for crimping operations. However, due to the integrated structure, the crimping mold needs to be replaced as a whole, which is cumbersome and costly. In order to solve this problem, a base 1, a crimping plate 6 and a limiting mechanism 7 are provided in the present scheme. The automobile wiring harness is crimped by the crimping plate 6, and at the same time, the crimping plate 6 is quickly limited and locked on the base 1 by the limiting mechanism 7, and the unlocking unit provided in the limiting mechanism 7 allows the crimping plate 6 and the base 1 to be quickly unlocked and separated, so that when the staff performs crimping operations on the automobile wiring harness, they can select the appropriate type of crimping plate 6 to connect with the base 1 according to actual conditions, and can also quickly disassemble and assemble, thereby reducing costs and greatly improving work efficiency.

[0027] Specifically, in this embodiment, the scheme mainly includes a base 1, a guide rod 2, a pressure plate 5, a crimping plate 6 and a limiting mechanism 7.
