[0002] After the heat shrink tube is put on the wiring harness terminal, it needs to be heated by a heat shrink machine. Conventional heat shrink machines can easily fail to fully fit the heat shrink tube on the wiring harness terminal after heating, resulting in gaps between the tube sleeve and the wiring harness terminal, which affects the heat shrink effect and makes it impossible to guarantee the production quality of the product.

[0003] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the utility model and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are described in the background technology section of the utility model.

When the sleeve sleeved at the wiring harness terminal is heated in the heat shrink machine and heat-shrunk, the plastic sleeve sleeve can be squeezed by the galvanized pressing rod to allow the sleeve to fully fit the wiring harness terminal, thereby improving the effect of the wiring harness heat shrink sleeve and ensuring the production quality of the product.

[0007] Furthermore, the pressing rod is arranged in parallel with the jig tray on which the wire harness is placed, and the pressing rod is located above the jig tray. When the pressing rod descends, all the tube sleeves on a row of wire harnesses in the jig tray can be squeezed at the same time; the pressing rod arranged horizontally and parallel to the jig tray can simultaneously squeeze the heat shrink tubes on the wire harnesses arranged in a row in the jig tray when pressed down, thereby improving work efficiency. The placement position of the wire harness in the jig tray can be achieved through the positioning structure so that all the wire harnesses are placed consistently, so that the heat shrink tubes of the wire harnesses can also be arranged in a row.
