[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model proposes a combined commutator that is easy to disassemble and assemble, including a fixing ring 1 and a copper sheet 2. A plurality of copper sheets 2 are adhered to the outer surface of the fixing ring 1. The fixing ring 1 provides fixing points for the copper sheets 2 and the fixing rods 4 installed on its outer surface, and is simultaneously mounted on the outer surface of the external fixed shaft to complete the initial fixation of the commutator. The copper sheets 2 are adhered to the outer surface of the fixing ring 1. When the commutator as a whole rotates under the influence of external force, the copper sheets 2 come into contact with the external brushes to convert alternating current into direct current. Mica sheets 3 are installed on the inner side of the copper sheets 2. The mica sheets 3 are installed on the inner side of the copper sheets 2 to separate the copper sheets 2.

[0022] The working principle of a combined commutator that is easy to disassemble and assemble based on the first embodiment is: first, the fixed shaft is inserted into the inner side of the fixed ring 1, and the fixed shaft is fixed through the extension rod 5, the spring 6, the clamping block 7 and the rough layer 8, and the armature winding is inserted into the inner side of the connecting hole 10 through external force, and the armature winding is bent to complete the fixation of the commutator. The copper sheet 2 is adhered to the outer surface of the fixed ring 1. When the commutator as a whole rotates under the influence of external force, the copper sheet 2 comes into contact with the external brush, thereby converting alternating current into direct current.

Compared with the first embodiment, this embodiment also includes: a fixing ring 1 and a fixing rod 4. A plurality of fixing rods 4 are installed on the inner side of the fixing ring 1. The fixing rod 4 is installed to the inner side of the fixing ring 1 to provide a connection point for an extension rod 5 that is embedded and connected to the inner side thereof, and at the same time to provide a fixing point for a spring 6 installed inside thereof. An extension rod 5 is embedded and connected to the inner side of the fixing rod 4. Driven by the spring 6, the extension rod 5 drives a clamping block 7 installed at its tail end to move inward. A spring 6 is installed inside the fixing rod 4, and the tail end of the spring 6 is connected to the inside of the extension rod 5. The spring 6 accumulates elastic potential energy inside it, and the spring 6 transmits the elastic force to the inside of the extension rod 5. A clamping block 7 is installed at the tail end of the extension rod 5, and the clamping block 7 is installed to the extension rod 5. The tail end of the extension rod 5 generates a clamping force on the external fixed shaft under the drive of the extension rod 5, thereby completing the fixation of the fixed shaft and providing a fixing point for the rough layer 8 installed on its outer surface. The outer surface of the clamping block 7 is installed with a rough layer 8, and the rough layer 8 is made of rubber material and installed on the outer surface of the clamping block 7, thereby improving the roughness of the clamping block 7 when in contact with the external fixed shaft, thereby improving the stability of the external fixed shaft after fixation. Two groups of connecting plates 9 are installed on the outer surface of the copper sheet 2, and the connecting plates 9 provide fixing points for the connecting holes 10 penetrated through the outer surface of the connecting plates 9.
