[0002] In new energy motors, the motor oil pipe space is small and the installation precision is high, and the oil pipe is fixed by the bracket plate during installation. Figure 1 , which is a schematic diagram of the structure of an existing double arc bracket plate. It includes a middle part A1, a first connecting part A2 and a second connecting part A3, wherein: one end of the middle part A1 is vertically connected to the first connecting part A2, and the other end of the middle part A1 is connected to the second connecting part A3. The second connecting part A3 is a double arc shaped grabbing part. The reason why the second connecting part A3 is a double arc shaped grabbing part is that the motor oil pipe that needs to be connected to the second connecting part A3 is also double arc shaped, such as Figure 2 , that is, both the X and Y directions are arcs.
