The multifunctional snow chain has both rescue and anti-slip functions. Snow chains are mainly used on icy roads in winter. A single snow chain is tied to car tires with straps so that the car can drive safely in ice and snow. The escape plate is mainly used in harsh outdoor rescue such as deserts or swamps. In a crisis, a single snow chain module can be combined into an escape plate for use. The stowage plate can be rolled up during storage, which solves the problem that the existing stray plate storage takes up a lot of space in the car.
