[0030] As the instruction manual Figure 1 , 2 As shown in Figures 4 and 5, a second connecting shaft is fixedly provided on one side of the sliding member 3.4, and a second connecting rod 3.7 is rotatably connected to the corresponding second connecting shaft. A pair of sliding members 3.4 penetrates the corresponding horizontal plate 2, and a sliding groove for sliding the sliding member 3.4 is provided on the horizontal plate 2. A threaded column is provided at one end of the sliding member 3.4, and a first threaded groove for threaded rotation connection of the threaded column is provided at one end of the threaded shaft 3.5. The threaded shaft 3.5 is matched with the threaded rotation of the threaded column through the first threaded groove, so that the threaded shaft 3.5 can be fixedly provided on the sliding member 3.4. A second threaded groove for threaded rotation connection of the threaded shaft 3.5 is provided on the rotating member 3.6. The threaded rotation of the threaded shaft 3.5 and the second threaded groove is matched, so that the rotating member 3.6 can move along the threaded shaft 3.5. A rubber sleeve is provided at the bottom of the threaded shaft 3.5, so that the threaded shaft 3.5 and the brake drum are separated by the rubber sleeve to reduce the wear on the brake drum.

[0031] As the instruction manual Figure 1 , 2 As shown in Figures 3 and 4, a connecting assembly 4 is provided on the transverse board 2. The connecting assembly 4 includes a first connecting rod 4.1 rotatably arranged between adjacent transverse boards 2, a motor 4.2 fixedly arranged on one of the brackets 1, and the motor 4.2 drives the corresponding transverse board 2 to rotate. A pair of rotating wheels 5 are provided at the bottom of a pair of brackets 1, and a stopper is provided on the rotating wheels 5. The stopper can lock the rotating wheels 5.

[0032] The working principle of this utility model:

[0033] Start the motor 4.2, and drive the rotating shaft on one side of the bottommost horizontal plate 2 to rotate through the output shaft of the motor 4.2, so that the horizontal plate 2 rotates around the rotating shaft, and then the first connecting rods 4.1 on both sides are driven to move through the third connecting shaft on the horizontal plate 2. Since the other end of the first connecting rod 4.1 is rotatably set on the adjacent horizontal plate 2, it will drive the adjacent horizontal plate 2 to rotate around the corresponding rotating shaft, and then the adjacent horizontal plate 2 is driven to rotate through the first connecting rod 4.1 on the other side, and finally all the horizontal plates 2 are in an inclined state, which is convenient for the subsequent placement of the brake drum.

[0034] The brake drum is placed on the horizontal plate 2, and then the motor 3.2 is started. The output shaft of the motor 3.2 drives the turntable 3.3 to rotate, and the turntable 3.3 drives the corresponding sliding member 3.4 to move through the second connecting rod 3.7, so that the sliding member 3.4 slides along the sliding groove on the horizontal plate 2. Since the sliding member 3.4 is provided with a threaded shaft 3.5 for rotation, the threaded shaft 3.5 is driven to move, so that the threaded shaft 3.5 contacts the inner side of the brake drum, and then the rotating member 3.6 is rotated, so that the rotating member 3.6 moves along the threaded shaft 3.5, so that the bottom of the rotating member 3.6 contacts the brake drum, thereby limiting the position of the brake drum.

[0035] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
