Description

A kind of multifunctional vehicle tool and its using method

technical field

The invention belongs to the technical field of auto parts, and in particular relates to a multifunctional on-board tool and a method for using the multifunctional on-board tool.

Background technique

At present, some on-board tools are usually equipped in the car, so that when people travel, they can solve minor problems in some emergencies while driving by themselves, such as changing tires or disassembling maintenance parts by themselves. The most common on-board tools include: jack, jack rocker, tire dismounting wrench, and tow hook. But in the prior art, the jack rocker, the tire dismounting wrench, and the tow hook are basically completely separated parts, which have no connection during use and have a single function. As a result, there are many on-vehicle tool components in existing vehicles, which occupy a large space in the luggage compartment. In addition, when the vehicle tire fails and needs to be replaced, it is time-consuming and labor-intensive to lift the vehicle with a traditional hand jack. If a female car owner uses it, she will find it laborious and not very convenient and difficult to use. It is more time-consuming to tighten the tow hook assembly with other tools, and it is inconvenient, time-consuming and labor-intensive when changing tires, dismounting and tightening tire nuts.
