[0021] See Figures 1-5 As shown, an automobile body lifting device in an embodiment of the present utility model includes a transmission rod 1. One end of the transmission rod 1 is fixedly connected with a handle 2. A storage groove 3 is opened at the central position of the transmission rod 1. A limiting groove 4 is opened at the top end of the storage groove 3. A guiding groove 5 is opened at one side of the top end of the storage groove 3. Circular grooves 6 are opened on both sides of the tail end of the guiding groove 5. A return spring 7 is fixedly connected to one side of each circular groove 6. A pressing ball 8 is fixedly connected to the opposite side of the two return springs 7. The pressing ball 8 is slidably connected with the circular groove 6. One side of the top end of the transmission rod 1 is fixedly connected with a first support rod 9. The top end of the first support rod 9 is fixedly connected with a first bearing block 10. Circular shafts 11 are fixedly connected to both lateral sides at one end of the transmission rod 1. Rollers 12 are rotatably connected to the circular shafts 11. A second support rod 13 is slidably connected in the storage groove 3. A limiting block 14 is fixedly connected to the bottom end of the second support rod 13. One end of the second support rod 13 is fixedly connected with a second bearing block 15. A transmission ring 16 is rotatably connected to the end of the second support rod 13 away from the second bearing block 15. An adjusting rod 17 is fixedly connected to the transmission ring 16.

[0022] The guiding groove 5 is designed with an L-shaped structure. The adjusting rod 17 is slidably connected with the guiding groove 5, which is convenient for the adjusting rod 17 to move along the guiding groove 5. The top end of the first bearing block 10 is designed with a concave structure, and the concave part corresponds to the reinforcement part of the car lifting mark at the bottom end of the car, which is convenient for lifting the automobile body. Reinforcing ribs are provided at the angle between the transmission rod 1 and the first support rod 9, and reinforcing ribs are provided at the angle between the transmission rod 1 and the circular shaft 11, which is convenient for the first support rod 9 to evenly conduct the pressure to the transmission rod 1 and the circular shaft 11, enhancing stability. The two pressing balls 8 are arranged corresponding to the adjusting rod 17, which is convenient for the pressing balls 8 to block and limit the adjusting rod.

[0023] When using the utility model, the groove of the first pressure-bearing block 10 is aligned with the lifting mark reinforcement at the bottom of the vehicle. After alignment, the transmission rod 1 is pressed down through the grip 2. The transmission rod 1 then drives the round shaft 11 to move towards the bottom of the vehicle body. The round shaft 11 then drives the roller 12 to move towards the bottom of the vehicle body through the roller 12. At this time, the transmission rod 1 and the first support rod 9 form a 90-degree lever to lift a corner of the vehicle body. The adjusting rod 17 drives the transmission ring 16 to rotate. The rotating adjusting rod 17 squeezes the extrusion ball 8. The squeezed extrusion ball 8 squeezes the return spring 7. At the same time, the extrusion ball 8 is received in the round groove 6 under the action of the squeezing force. The adjusting rod 17 slides along the guiding groove 5. The adjusting rod 17 drives the second support rod 13 to extend from the receiving groove 3 of the transmission rod 1 through the transmission ring 16. The second support rod 13 then drives the second pressure-bearing block 15 to move. At this time, the transmission rod 1, the round shaft 11 and the second support rod 13 form a cross-shaped structure, which can stably support the vehicle body.
