The center of the bearing installation groove 23 corresponds to the center of the through hole 22, and the rotary bearing 24 is embedded in the bearing installation groove 23. When the rotating shaft 111 passes through the through hole 22, the rotating shaft 111 can synchronously pass through the bearing installation groove 23, so that the rotating bearing 24 is sleeved on the rotating shaft 111. The power extension 26 surrounds the bearing mounting groove 23. Meanwhile, the power extension part 26 protrudes from the surface of the connecting plate 2, so that when the connecting plate 2 is connected with the power casing 1, the power extension part 26 can extend into the power casing 1. The dynamic seal groove 25 surrounds the dynamic extension part 26, and a rubber ring is embedded in the dynamic seal groove 25. One side of the connecting plate 2 close to the electric control casing 3 is provided with a mounting groove 27 and an electric control sealing groove 28. The mounting groove 27 corresponds to the through hole 22. The encoder 311 is installed in the installation groove 27. Preferably, a protective casing capable of covering the encoder 311 may be additionally disposed in the mounting groove 27 to prevent the encoder from being damaged due to impact of external force. The outer wall of the mounting groove 27 protrudes out of the connecting plate 2. When the connecting plate 2 is connected to the electronic control housing 3, the outer wall of the mounting groove 27 can extend into the electronic control housing 3. The electric control sealing groove 28 surrounds the periphery of the mounting groove 27, and a rubber ring is embedded in the electric control sealing groove 28. Meanwhile, the connecting plate 2 is further provided with a connecting through hole 29, the connecting through hole 29 penetrates through the connecting plate 2, and the connecting through hole 29 has a certain width so that a wire can pass through the connecting plate 2 through the connecting through hole 29.
