After that, the first motor 51 drives the connecting frame 12 to a vertical state, thereby reducing the length and promoting convenient transportation.

[0027] Further, such as Figure 1 and 3 -4, the connecting frame 12 is fixedly connected with a second motor 41; the rotating shaft 21 and the output end of the second motor 41 are both fixedly connected with a first gear; a plurality of chains 43 are installed on the first gears; when in use, when the connecting frame 12 is rotated and placed horizontally, the second motor 41 drives the chain 43 to move through the first gear, thereby driving the plurality of connecting frames 12 to move accordingly, so that the connecting frame 12 is in a horizontal state, which is convenient for placing and fixing the steering gear of the vehicle.

[0028] Further, such as Figure 1 and 4 As shown, the top of the connecting frame 12 is rotatably connected to a support shaft 62; a second gear 42 is fixedly connected to the support shaft 62; the chain 43 is connected to the second gear 42; both ends of the support shaft 62 are fixedly connected to support legs 61; when in use, when the connecting frame 12 is rotated and placed horizontally, the chain 43 will drive the second gear 42 to rotate, so that the support shaft 62 and the support leg 61 can rotate and unfold, and the unfolded support leg 61 can support the end of the connecting frame 12 away from the frame 11, thereby improving stability.

[0030] Working principle: when in use, in the initial state, the placement frame 14 is parallel to the connecting frame 12, and the staff puts the automobile universal joint into the lower seat 15, and then rotates the placement frame 14. During the rotation, the shaft rod 22 contacts the top wheel 23, and the top wheel 23 pushes the shaft rod 22 to move downward, thereby pulling the moving frame 24 to move downward. During the downward movement, the slide seat 25 slides on the moving frame 24 and pulls the pull rod 16 and the top seat 17 to move downward. The oblique rod is inclined to make the top seat 17 close and close with the lower seat 15, so as to fix the automobile universal joint, so as to reduce the shaking of the automobile universal joint during transportation, thereby reducing the collision of the automobile universal joint during transportation. When in use, the vertical rod 31 is used to guide and position the movement of the moving frame 24, the spring is used to drive the moving frame 24 to move upward, and then drive the top seat 17 to move upward and open, and the pulley 32 is used to lower the shaft rod 22 and the top wheel 23.

Then the first motor 51 drives the connecting frame 12 to become a vertical state again, so as to reduce the length and promote convenient transportation. During the process of rotating and horizontally placing the connecting frame 12, the second motor 41 drives the chain 43 to move through the first gear, and then drives multiple connecting frames 12 to move accordingly, so that the connecting frame 12 is in a horizontal state, which is convenient for storing and fixing the automobile steering machine. When the connecting frame 12 is rotated and placed horizontally, the chain 43 will drive the second gear 42 to rotate, so as to rotate the support shaft 62 and the support leg 61 to unfold, and the unfolded support leg 61 can support the end of the connecting frame 12 away from the frame 11 to improve stability.
