[0021] The first C-shaped rod 16 is rotatably mounted on the opposite side of the four truncated tables 15, and the first support plate 17 is fixedly mounted on the upper side of the four first C-shaped rods 16. Two support columns 18 symmetrically distributed on the left and right sides are fixedly mounted on the lower side of the four truncated tables 15. The side walls of the four support columns 18 close to the bidirectional screw 11 are rotatably mounted with the first connecting rod 19. The upper sides of the four first connecting rods 19 are hinged to the lower sides of the corresponding four first C-shaped rods 16. The four first C-shaped rods 16 are provided with a first elliptical groove 20. The second C-shaped rod 21 is rotatably mounted on the side of the four truncated tables 15 away from the bidirectional screw 11. The second support plate 22 is fixedly mounted on the upper side of the four second C-shaped rods 21. The side walls of the four support columns 18 away from the bidirectional screw 11 are rotatably mounted with the second connecting rod 23. The upper sides of the four second connecting rods 23 are hinged to the lower sides of the corresponding four second C-shaped rods 21. The four second C-shaped rods 21 are provided with a second elliptical groove 24.
[0022] During the use of the utility model, when different types of vehicles need to be hoisted, the operator controls the rotating assembly, and the rotating assembly controls the round table 15 to rotate, and the round table 15 drives the first C-shaped rod 16 and the second C-shaped rod 21 to rotate synchronously, and the positions of the first C-shaped rod 16 and the second C-shaped rod 21 are interchanged. The first connecting rod 19 and the second connecting rod 23 both increase the supporting force of the first C-shaped rod 16 and the second C-shaped rod 21. At the same time, by rotating the bidirectional screw 11, the two square rods 12 are moved synchronously, so as to adjust the distance between the two square rods 12, so as to hoist vehicles of different types;
[0023] The utility model rotates the round table by a rotating component, and the rotation of the round table drives the first C-shaped rod and the second C-shaped rod to rotate, so that the first C-shaped rod and the second C-shaped rod are switched, and different car models are hoisted, thereby improving the production efficiency of the car and reducing the production cost.
[0024] The rotating assembly includes a through groove matching the disc 14 on the upper side of the truncated table 15, a gear 25 is rotatably mounted on the upper side of the disc 14, a plurality of tooth grooves 26 distributed in a circumference are arranged on the upper side of the truncated table 15, and the plurality of tooth grooves 26 are meshed with the gear 25, a first motor 27 is mounted on the upper side of the disc 14, and the output shaft of the first motor 27 is transmission-connected with the upper side of the gear 25;
[0025] When controlling the rotating assembly, the output shaft of the first motor 27 drives the gear 25 to rotate, and the gear 25 engages with the tooth groove 26, synchronously driving the round table 15 to rotate. The rotation angle of the round table 15 is controlled by the gear 25, making the rotation of the round table 15 more precise, thereby ensuring the smooth operation of the device.
[0026] The lower sides of the four vertical rods 13 are each provided with a control member matching the first C-shaped rod 16 and the second C-shaped rod 21. The control member includes a circular cover 30 fixedly provided on the lower side of the vertical rod 13. A slide groove 31 is provided on the side wall of the circular cover 30. The slide groove 31 is composed of two semi-annular grooves 32 and two inclined grooves 33. The two semi-annular grooves 32 are symmetrically arranged on the side wall of the circular cover 30 and staggered up and down. The two inclined grooves 33 are connected end to end with the two semi-annular grooves 32. The upper sides of the first C-shaped rod 16 and the second C-shaped rod 21 are rotatably equipped with a long rod 34. The side wall of the circular cover 30 is slidably equipped with two blocks 35 symmetrically distributed on the left and right sides.

[0028] When it is necessary to switch the first C-shaped rod 16 and the second C-shaped rod 21, when the round table 15 rotates under the control of the first motor 27, the round table 15 synchronously drives the first C-shaped rod 16 and the second C-shaped rod 21 to rotate around the vertical rod 13, and at the same time drives the two long rods 34 to rotate, and the two long rods 34 synchronously drive the block 35 and the round shaft 36 to rotate, and the long rod 34, the block 35 and the round shaft 36 on the upper side of the first C-shaped rod 16 rotate from the semi-annular groove 32 on the lower side through the inclined groove 33 to the upper side. The first C-shaped rod 16 is tilted by the pull of the long rod 34, and the second C-shaped rod 21 rotates to drive the upper block 35 and the circular shaft 36 to rotate from the upper semi-annular groove 32 through the inclined groove 33 to the lower semi-annular groove 32. Under the synchronous control of the upper long rod 34, the second C-shaped rod 21 is in a completely horizontal state, ensuring the stability of the vehicle hoisting, and at the same time making the inclination angle of the first C-shaped rod 16 reach the maximum, so that the volume of the device is smaller and the weight is lighter;
[0029] Furthermore, the circular cover 30 prevents debris from falling onto the upper side of the disc 14 , thereby ensuring the normal rotation of the gear 25 .
[0030] A second motor 40 is installed at the front side of the frame 1 , and the output shaft of the second motor 40 is drivingly connected to the front side of the bidirectional screw 11 , so as to facilitate the control of the bidirectional screw 11 to rotate.
