then starting the direction limiting mechanism, and screwing the rotating handle to enable the jack to move only in the direction far away from the shallow pit;

then the jack is lifted, so that the rubber pad of the contact block is contacted with the fin or the reinforcing rib of the automobile chassis;

then, continuously lifting the jack to jack the chassis of the automobile to a proper position, so that the wheels are lifted to a proper height;

then driving or pushing the automobile to go straight to enable the wheels to leave the shallow pit;

if the two wheels are both sunk into a shallow pit and can not be driven away, two sets of automobile rescue devices can be adopted according to specific actual conditions.

Note: 1. the support points (the support positions for jacking by the jacks) of the household vehicle are usually on the inner side of the side skirt, similar to two fins on two sides of the chassis, and are about 20 cm behind the front wheel and about 20 cm in front of the rear wheel. The fins are protruded out of the steel plate of the chassis and can bear relatively large pressure compared with other places. The reinforcing ribs are thin plates which are connected with the two fins on the same side, and can also be used for supporting automobiles.

2. If the automobile is driven forwards or backwards, if the wheels sunk into the pit are driving wheels and the automobile slips, and the automobile is not provided with a differential lock, the automobile can be pushed to leave the shallow pit only by force and cannot be driven to leave the shallow pit by using the invention.
