[0002] As we all know, starter rods are often used in motorcycles and are the starting devices of motorcycles. In order to improve the mechanical strength, wear resistance, fatigue resistance and corrosion resistance of parts, motorcycle starter rods are shot peened during preparation. That is, shots are used to bombard the surface of the workpiece and implant residual compressive stress, thereby improving the fatigue strength of the workpiece through a cold processing process.

[0003] After searching, it was found that a motorcycle starter rod surface treatment device is disclosed with application number CN202321656860.1, which mechanically clamps the motorcycle starter rod through a clamping assembly, and then performs shot peening on the clamped workpiece through high-speed spraying of pellets. However, the clamping assembly is clamped on the outer wall of the starter rod, and the clamping assembly partially blocks the outer wall of the starter rod, resulting in uneven treatment of the outer wall of the starter rod.
