In order to provide good support and fixation for the oil pump, the oil pump is usually fixed on the oil pump bracket, and then the oil pump bracket is fixed to the blister oil storage tank. The commonly used fixing method is screw tightening, which uses the screws to pass through the blister oil storage tank and the oil pump bracket from top to bottom, and then screw them into the threaded holes of the oil pump bracket for fastening. Due to the small opening of the blister oil storage tank, it is difficult to align the oil pump bracket with the mounting holes of the blister oil storage tank during assembly, which makes the installation of the oil pump difficult. Especially when the screws are removed and the oil pump is ready to be taken out for maintenance, the oil pump will fall to the bottom of the blister oil storage tank and is difficult to take out, which makes assembly, repair and maintenance inconvenient.
