By fixing multiple installed oil pump push rods through the clamping groove 5 between the front positioning block 2 and the rear positioning block 4, and fixing multiple oil pump push rods through multiple clamping grooves 5, the efficiency of spare parts assembly is improved, and the efficiency of production is improved.

[0021] Reference Figure 1 The pushing assembly includes a push rod 12 fixedly connected to one side of the rear positioning block 4, a fixed block 9 is fixedly connected to the top surface of the connecting plate 8, a sleeve 11 is provided on the fixed block 9, the push rod 12 slides in the sleeve 11, a connecting rod 13 is provided between the push rod 12 and the connecting rod 14, the connecting rod 13 is located on both sides of the push rod 12 and the connecting rod 14, and the two ends of the connecting rod 13 are rotatably arranged on the push rod 12 and the connecting rod 13 respectively. Through the rotation of the connecting rod 14, the connecting rods 13 on both sides of the connecting rod 14 push the push rod 12 in the sleeve 11 to move toward the front fixed block 9, so that the clamping groove 5 between the front fixed block 9 and the rear fixed block 9 fixes the oil pump push rod parts.
