Description

Multifunctional vehicle-mounted tool

Technical Field

The utility model belongs to the technical field of automobile maintenance facility equipment, and particularly relates to a multifunctional vehicle-mounted tool.

Background

When the situation that the tire is damaged and leaked is frequently encountered in the running process of the automobile, the tire pressure is insufficient, the tire is required to be inflated or corresponding repairing operation is required, and when the situation happens, the automobile is often not near a repair shop, and sometimes on some roads with larger traffic flow, the automobile tire is required to be quickly and reliably subjected to emergency repair work. The existing emergency repair method mainly uses an inflator pump and tire repair liquid, specifically, the inflator pump is required to input high-pressure gas into the tire, meanwhile, the tire repair liquid is required to be pressed in together, after the tire repair liquid and air are pressed into the automobile tire, the tire repair liquid can be atomized under the action of compressed air, and the atomized tire repair liquid is covered on the inner wall of the whole tire along with the rolling of the wheel under the action of centrifugal force, so that the tire repair liquid is finally adhered to the broken part of the automobile tire, and the repair operation of the automobile tire is realized.
