[0002] A jack is a simple lifting device with a small lifting height (less than 1m). It uses a rigid lifting piece as a working device and lifts heavy objects within the stroke through a top support or a bottom claw. There are two types: mechanical and hydraulic. Jacks are mainly used in factories, mines, transportation and other departments for vehicle repairs and other lifting and supporting work.

[0003] The existing electric jacks used for car repair are large in size due to the heavy weight of the car, and can lift a high weight, but are not easy to move. The existing jacks are portable and movable through universal wheels, but when supporting heavy objects, the universal wheels have insufficient supporting force, and long-term use can easily cause the universal wheels to break, affecting subsequent use, and there are certain safety hazards. Therefore, it is necessary to redesign an electric jack for car repair to address the above problems. Utility Model Content

The top end of one of the threaded rods 12 passes through the top wall of the installation cavity 13 and is extended to be installed with a motor 2, and the motor 2 is fixedly installed on the upper end surface of the installation base 1 through a fixing frame. It should be noted that the motor 2 can be used to drive the threaded rod 12 to rotate, and the synchronization component can be used to make the two threaded rods 12 rotate synchronously.

[0023] The synchronization assembly includes a first synchronization wheel 10 and a second synchronization wheel 9, and the first synchronization wheel 10 and the second synchronization wheel 9 are respectively fixedly installed on the upper end surface of a threaded rod 12 at corresponding positions, and a synchronization belt 11 is fixedly connected between the first synchronization wheel 10 and the second synchronization wheel 9. It should be noted that the first synchronization wheel 10 can drive the second synchronization wheel 9 to rotate synchronously through the synchronization belt 11.

[0024] The supporting device includes a mounting plate 8, and the mounting plate 8 is threadedly connected to two threaded rods 12, and the mounting plate 8 is slidably clamped on the inner wall of the mounting cavity 13, and a plurality of fixing columns 7 are fixedly installed on the lower end surface of the mounting plate 8, and one end of each fixing column 7 away from the mounting plate 8 passes through the bottom wall of the mounting cavity 13 and extends outward to be installed with a load-bearing block 3.

[0025] Each buffer device includes a spring 5, and the spring 5 is fixedly connected in the slide groove. One end of the spring 5 is fixedly connected to a connecting block 6, and the connecting block 6 is slidably clamped in the slide groove, and the universal wheel 4 is fixedly installed at the bottom end of the connecting block 6.
