[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a retractable automobile traction device, including: a support frame 2, a rotating shaft 11 movably penetrates the top of the support frame 2, a disc 6 is fixedly connected to the top of the rotating shaft 11, a sliding rod 13 symmetrically and movably penetrates the top of the disc 6, a connecting ring 12 is fixedly connected between the bottoms of the two sliding rods 13, a plurality of limiting rods 10 are fixedly connected to the bottom of the connecting ring 12 at equal intervals, a plurality of limiting holes 15 are equidistantly opened on the top of the support frame 2, a rotating disk 5 is fixedly connected to the outer surface of the rotating shaft 11, a traction rope 3 is fixedly connected to the outer surface of the rotating disk 5, and the traction rope 3 is fixedly connected to the outer surface of the rotating disk 5. A traction ring 4 is fixedly connected to the left end face, the inner surfaces of the multiple limit holes 15 are respectively slidably arranged with the outer surfaces of the multiple limit rods 10, the bottom of the rotating shaft 11 is rotatably connected to the inner bottom of the support frame 2, the top of the two sliding rods 13 is fixedly connected to a connecting block 14, the top thread of the connecting block 14 is penetrated by a threaded rod 9, the bottom of the threaded rod 9 is rotatably connected to the top of the disc 6, the top of the threaded rod 9 is fixedly connected to a turning handle, the turntable 5 is located on the inner side of the support frame 2, the top of the disc 6 is fixedly connected to a handle 7 near the edge, and the right surface of the support frame 2 is fixedly connected to a connecting head 8.

[0024] The effect achieved by the entire embodiment 1 is that when in use, it is connected to the car through the connecting head 8. When the towing ring 4 is needed to tow the external car, the threaded rod 9 can be rotated by turning the handle to make the threaded rod 9 rotate on the disc 6, thereby driving the connecting block 14 to move upward, driving the sliding rod 13 to rotate upward along the disc 6, so that the connecting ring 12 and the limiting rod 10 move upward, so that the multiple limiting rods 10 will be disengaged from the limiting holes 15, so that they are no longer engaged, so that the disc 6 can rotate, and then the towing ring 4 is dragged to make the rotating disk 5 rotate along the rotating shaft 11, so that the winding The traction rope 3 wound around the turntable 5 is unfolded to move the traction ring 4 outward. When the traction ring 4 is connected to the external car, the threaded rod 9 is rotated in the opposite direction to drive the connecting block 14 to move downward, so that the sliding rod 13 and the connecting ring 12 move downward, so that the limiting rod 10 will be inserted into the limiting hole 15, and the disc 6 is limited so that it cannot rotate. By fixing the disc 6 and the rotating shaft 11, the turntable 5 will not rotate either. Therefore, the telescopic position of the traction ring 4 can be adjusted as needed. This telescopic adjustment allows the device to be used for cars of various sizes, increasing its flexibility and practicality.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, a spring hook 1 is fixedly connected to the left surface of the support frame 2, and the spring hook 1 is matched with the traction ring 4.

[0026] The effect achieved by the entire embodiment 2 is that when the traction ring 4 needs to be stored, the limit rod 10 is disengaged from the limit hole 15, and then the handle 7 is rotated to rotate the disc 6 and the turntable 5 to wind and store the traction rope 3. After the storage is completed, the threaded rod 9 is rotated to insert the limit rod 10 into the limit hole 15, and then the traction ring 4 is fixed by the spring hook 1 to complete the storage of the device, which has high usability.

[0027] Working principle: When in use, it is connected to the car through the connecting head 8. When the towing ring 4 is needed to tow the external car, the threaded rod 9 can be rotated by turning the handle to make the threaded rod 9 rotate on the disc 6, thereby driving the connecting block 14 to move upward, driving the sliding rod 13 to rotate upward along the disc 6, so that the connecting ring 12 and the limiting rod 10 move upward, so that the multiple limiting rods 10 will disengage from the limiting holes 15, so that they are no longer engaged, so that the disc 6 can rotate, and then drag the towing ring 4 to make the turntable 5 rotate along the rotating shaft 11, so that the towing rope 3 wrapped around the turntable 5 is unfolded, so that the towing ring 4 moves outward. After the towing ring 4 is connected to the external car, the threaded rod 9 is rotated in the opposite direction to drive the connecting block 14 to move upward. The block 14 moves downward, causing the sliding rod 13 and the connecting ring 12 to move downward, so that the limiting rod 10 will be inserted into the limiting hole 15, limiting the disc 6 so that it cannot rotate, and the turntable 5 will not rotate by fixing the disc 6 and the rotating shaft 11, so that the towing work can be carried out. Therefore, the telescopic position of the traction ring 4 can be adjusted as needed. When the traction ring 4 needs to be stored, the limiting rod 10 is disengaged from the limiting hole 15, and then the handle 7 is turned to rotate the disc 6 and the turntable 5, and the traction rope 3 is wound and stored. After the storage is completed, the threaded rod 9 is turned to insert the limiting rod 10 into the limiting hole 15, and then the traction ring 4 is fixed by the spring hook 1 to complete the storage of the device, which has high usability.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
