[0020] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0021] Example:

[0022] like Figure 1-4 As shown, a cylinder 1 is fixedly mounted on an L-shaped mounting plate 2, a connecting rod 4 is connected to the telescopic end of the cylinder 1, and a circular ring plate 15 is fixedly connected to one end of the connecting rod 4 away from the cylinder 1, and the circular ring plate 15 is in a circular ring shape.

[0023] Two first side plates 5 are fixedly connected to the top of the L-shaped mounting plate 2, a first pin 6 is rotatably connected between the two first side plates 5, and two rod connections of the folding connecting rod 7 are fixedly connected to the outer wall of the first pin 6. A notch 13 is provided at the bottom of the folding connecting rod 7, a rotating column 14 is connected between the two side walls of the notch 13, and a circular plate 15 is sleeved on the outer wall of the rotating column 14. The inner diameter of the circular plate 15 is larger than the outer diameter of the rotating column 14, so that the folding connecting rod 7 can rotate stably when the cylinder 1 is extended.

[0024] The second side plates 8 are fixedly connected to both sides of the bottom of the shoe fixing plate 12 , a second pin shaft 9 is rotatably connected between the two second side plates 8 , and the top of the folding connecting rod 7 is fixedly connected to the outer wall of the second pin shaft 9 .

[0025] The top of the shoe fixing plate 12 is fixedly connected with a brake shoe 10 , and a concave surface 11 is formed in the middle of the brake shoe 10 .

[0026] Side protection plates 3 are fixedly connected to both sides of the L-shaped mounting plate 2 , and a connecting rod 4 is located between the two side protection plates 3 .

[0027] In the specific implementation, in order to ensure that the whole vehicle is installed on the chassis dynamometer before the test, the hub is prevented from rotating and the vehicle is smoothly installed on the hub. This device is designed. First, the device is placed at the bottom of the hub. At this time, the solenoid valve switch of the cylinder 1 is started so that the cylinder 1 drives the connecting rod 4 to extend. At this time, the connecting rod 4 drives the folding connecting rod 7 to rotate through the circular ring plate 15. The concave surface 11 on the top of the folding connecting rod 7 presses the hub to stop the hub. The rotatable brake shoe 10 prevents the hub from being damaged.

[0028] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
