A connecting rod 5 is fixedly connected to the upper side of the connecting plate 2. An output top plate 6 is fixedly connected to the top of the connecting rod 5. The output top plate 6 is fixedly connected to the output end of the hydraulic cylinder 3. A fixed platform 7 is fixedly connected to the bottom of the hydraulic cylinder 3. A hydraulic connector 8 is provided on the surface of the hydraulic cylinder 3. The hydraulic connector 8 is connected to the hydraulic station 1 through a hydraulic pipeline. An extension plate 9 is provided on the outer side of the surface of the fixed platform 7. A fixed support rod 10 is provided at the end of the extension plate 9, connecting the connecting plate 2 and the motor drive plate. Pulling is achieved by using the hydraulic cylinder 3 as the driving force. Combining advanced electric and hydraulic technologies, it has a powerful pulling force, precise control capability, and stable performance. Its structure is compact, easy to operate, and can adapt to the complex working environment of the maintenance workshop, ensuring work efficiency.

[0022] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, fixing holes 4 are distributed on the surface of the connecting plate 2, and the size of the fixing holes 4 is different. There are five connecting rods 5 arranged in a ring array. The connecting rods 5 and the fixing platform 7 are slidably connected. The bottom of the fixing platform 7 is provided with a reinforcing frame, which is adapted to the extension plate 9. The hydraulic cylinder 3 drives the output top plate 6 to move. Through the connection of the connecting rods 5, the connecting plate 2 drives the drive plate to move outward, or the hydraulic cylinder 3 retracts to install the drive plate onto the drive shaft, realizing the pull-out operation, which facilitates the installation and disassembly of the drive plate and improves convenience.

[0023] Please see Figure 2 and Figure 4 In this embodiment, two hydraulic connectors 8 are provided, forming a circulating oil circuit with the hydraulic cylinder 3. The top of the fixed support rod 10 is fixedly connected to the extension plate 9. A support rod is provided between the upper end of the extension plate 9 and the hydraulic cylinder 3.

In use, the connecting plate 2 is first fixed by connecting the fixed bracket 10 to the operating surface to facilitate connection with the drive plate. The hydraulic cylinder 3 is connected to the hydraulic station 1 through a flexible hose. By opening and closing the hydraulic station 1, the operator can accurately control the pulling force, improving practicality and providing strong pulling force, precise control capability, and stable performance. Its structure is compact, easy to operate, and can adapt to the complex working environment of the maintenance workshop.

Then, the hydraulic cylinder 3 and the hydraulic station 1 are connected by a hose. The multiple fixing holes 4 on the connecting plate 2 are adapted to different drive plate structures. During pulling, the extension and retraction of the hydraulic cylinder 3 drives the output top plate 6 to move, realizing the pulling operation. This facilitates the installation and disassembly of the drive plate. At the same time, the operator can precisely control the pulling force by opening and closing the hydraulic station 1, improving practicality.
