[0036] The above-mentioned various structures jointly constitute the general appearance structure of the utility model of an auxiliary device for automobile maintenance.

[0037] Please focus on Figure 3To further explain the specific working principle of the auxiliary device for automobile repair, the lifting device 7 comprises a servo motor 701 located at the top end of the base 1, the servo motor 701 is self-locking, and the servo motor 701 is fixedly connected to the base 1 through the motor seat 710, followed by a conical gear one 702 on the side of the servo motor 701 away from the center of the base 1, followed by two symmetrically arranged threaded columns 709 fixedly connected to the side of the receiving table 3 close to the servo motor 701 at the bottom end, then the threaded rods 708 are threadedly connected to the two threaded columns 709, when the threaded rods 708 rotate, the threaded columns 709 can drive the receiving table 3 to rise and fall, followed by a worm gear 706 fixedly connected to the bottom end of the threaded rod 708, and a rotating shaft 707 fixedly connected to the bottom end of the worm gear 706, it should be pointed out that the bottom end of the rotating shaft 707 is rotatably connected to the base 1;

[0038] At the same time, the worm gears 706 on both sides close to the servo motor 701 are engaged with the worm gears 704, that is, when the worm gears 704 drive the worm gears 706 to rotate, the worm gears 706 will drive the threaded rods 708 to rotate, followed by a rotating frame 705 rotatably connected to the outer wall of the two connecting shafts of each side worm gear 704, and the bottom end of the rotating frame 705 is fixedly connected to the base 1, and the proximal ends of the two worm gears 704 are fixedly connected with a conical gear two 703, and the two conical gears two 703 are engaged with the conical gear one 702, and the conical gear one 702 can drive the two conical gears two 703 to rotate at the same time.

[0039] The technical effects achieved by the technical scheme composed of the above technical features are that the servo motor 701 drives the conical gear one 702 to rotate, in this process, the conical gear one 702 drives the two conical gears two 703 to rotate, and the conical gear two 703 drives the worm gear 704 on the same side to rotate, since the worm gear 704 and the worm gear 706 are engaged, the worm gear 706 will drive the rotating shaft 707 and the threaded rod 708 to rotate at the same time, finally, when the threaded rod 708 rotates, the threaded column 709 threadedly connected thereto will drive the receiving table 3 to rise and fall.

[0040] Please pay attention to Figure 4As shown, in order to further explain the specific working principle of the auxiliary device for automobile maintenance, the fixing device 8 comprises a fixing plate 801 located at the top end of the receiving table 3, and the fixing plate 801 is also located between any two adjacent threaded holes 6. A threaded plate 807 is fixedly connected to the rear end of the top end of the fixing plate 801, and a lead screw 806 is threadedly connected to the threaded plate 807. The rear end of the lead screw 806 is fixedly connected to a rotating handle 808 with a locking function, and the front end of the lead screw 806 is rotatably connected to a fixing frame 805. The bottom end of the fixing frame 805 is fixedly connected to a positioning plate 804, and the bottom end of the positioning plate 804 is slidably connected to the fixing plate 801. When the rotating handle 808 drives the lead screw 806 to rotate, the fixing frame 805 drives the positioning plate 804 to displace.

[0043] The technical effects achieved by the technical scheme composed of the above technical features are as follows: after the fixing lug 802 is fixed at the top end of the receiving table 3, the rotating handle 808 drives the lead screw 806 to rotate together. The lead screw 806 is threadedly connected to the threaded plate 807, so that the lead screw 806 rotates while driving the fixing frame 805 to displace forward, and the fixing frame 805 drives the positioning plate 804 to slide forward. When the positioning plate 804 abuts against the wheel, the rotating handle 808 is stopped rotating, so that the positioning plate 804 limits the displacement of the automobile rearward.

[0044] Finally, it should be noted that after the lead screw 806 stops rotating, a limiting block with a corresponding length is inserted between the positioning plate 804 and the threaded plate 807, so that the displacement of the positioning plate 804 rearward is prevented. In addition, the lead screw 806 itself has a certain self-locking ability, so that the stable operation of the fixing device 8 is ensured.
