After that, the pull rod is released. Under the action of the spring, the pressure plate can be reset and the wiring harness can be compressed, which can prevent the wiring harness from falling off the socket when it is pulled.

[0007] Optionally, a connecting block is fixedly connected to the top end of the pull rod.

[0008] By adopting the above technical solution, the pull rod can be pulled more flexibly through the connecting block.

[0009] Optionally, an anti-slip layer is glued and fixed to the inner bottom end of the limiting frame.

[0010] By adopting the above technical solution, the anti-slip layer can increase the friction between the limit frame and the wire harness, preventing the wire harness from falling off when being pulled.

[0011] Optionally, a fixing block is fixedly connected to the outer wall of the airbag hairspring body, a screw is passed through the fixing block, and the screw is threadedly connected to the base.

[0012] By adopting the above technical solution, under the action of the fixing block and the screws, the firmness of the connection between the airbag hairspring body and the base can be improved.

[0013] Optionally, the base is provided with four mounting holes, and the four mounting holes are distributed in a ring shape.

[0014] The adoption of the technical solution is beneficial to the installation of the base.

[0015] Optionally, there are two springs in total, and the two springs are symmetrically arranged on the left and right.

[0016] The adoption of the technical solution is conducive to the smooth lifting and lowering of the pressing plate and avoids unevenness on both sides of the pressing plate.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] The technical solution of the present application first pulls the pressure plate up through the pull rod, then the wiring harness passes through the limit frame and is located under the pressure plate, and then the pull rod is released. Under the action of the spring, the pressure plate can be reset to tighten the wiring harness, which can prevent the wiring harness from falling off the socket when it is pulled.
