The pull plate 172 drives the pull rods 171 to move. The pull rods 171 drive the second slider 161 to move. The second slider 161 drives the sliding plate 14 to move, so that the sliding plate 14 moves to the middle position of the strengthening seat 1 and is located above the base of the jack 2. Then manually rotate the knob 153. The knob 153 drives the adjusting rod 151 to rotate, causing the adjusting rod 151 to move downward. The adjusting rod 151 drives the pressing plate 152 to press on the base of the jack 2, fixing the jack 2, preventing the jack 2 from shaking, facilitating the stable support of the jack 2, and improving the support effect of the jack 2;

[0034] Then manually rotate the throttle grip 112. The throttle grip 112 drives the lead screw 111 to rotate. The lead screw 111 drives the first slider 103 to move. The first slider 103 drives the second connecting rod 102 to move. The second connecting rod 102 then drives the first connecting rod 101 to swing. The first connecting rod 101 drives the rotating rod 7 to swing. The rotating rod 7 drives the second support rod 8 to swing, thereby driving the second support plate 9 to swing and adjusting the position of the second support plate 9. In this way, when the first support plate 5 and the second support plate 9 are in contact with the ground, the leveling of the strengthening seat 1 can be achieved, and thus the leveling of the jack 2 can be achieved, facilitating the stable support of the jack 2 and improving the support effect of the jack 2.
