[0009] Through the above technical solutions, the support plate can effectively prevent the first connecting rod and the second connecting rod from rotating downward, and can also play a certain supporting role during the installation process.

[0010] As a further improvement of the above solution, a limiting plate is fixedly connected to the outer wall of the fixed column. The bottom of the limiting plate is fixedly connected to the top of the first rotator. The top of the support disc is fixedly connected to a top plate. The bottom of the top plate contacts the top of the first connecting rod. The bottom of the top plate contacts the top of the second connecting rod. The outer wall of the top plate contacts the limiting plate.

[0011] Through the above technical solution, the limiting plate can prevent the top plate from swaying back and forth after installation, which affects the vehicle driving.

[0015] As a further improvement of the above solution, the diameter of the installation groove is larger than the diameter of the second threaded hole, and the second threaded hole is directly above the first threaded hole.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] In the present utility model, by pulling the fixed column to move away from the support disc, the support disc will drive the bottom end of the fixed rod to move, so that the top end of the fixed rod moves downward. The fixed rod pushes the support disc downward, and the support disc pushes the support column downward, so that the support column contacts the bottom surface. At the same time, the fixed column will drive the first rotator to move, and the first rotator drives the first connecting rod and the second connecting rod to move, so that the bottoms of the first connecting rod and the second connecting rod contact the support plate. The support plate will limit the first connecting rod and the second connecting rod, so as to ensure that the first connecting rod and the second connecting rod are in a horizontal state, and the device can be opened. On the contrary, the device can be folded for easy transportation.

[0018] In the present utility model, by placing the top plate on the support disc, the top plate is located inside the four limiting plates. At the same time, the second threaded hole is aligned with the first threaded hole. Then the bolt is screwed into the first threaded hole and the second threaded hole, so as to fix the top plate on the top of the support disc. At the same time, the fixed rod and the support disc will support the top plate, and the support plate will support the fixed rod. The support column will support the support disc, which can effectively improve the stability of the device. Description of the Drawings
