[0002] The rocker arm assembly helps to open and close the intake valve and exhaust valve regularly in an automobile engine. This function directly affects the normal operation of the engine, and thus directly affects the gas exchange efficiency of the engine. The rocker arm assembly includes components such as a rocker arm, a rocker shaft, a support seat, and a valve clearance adjusting screw. Among them, the rocker shaft converts the rotational motion of the camshaft into the reciprocating motion of the rocker arm, and then pushes the valve to open and close. When assembling the rocker arm assembly, it is necessary to first assemble the components of the rocker shaft to complete the overall assembly. At the same time, in order to facilitate the later installation, a plurality of positioning blocks need to be arranged on the rocker shaft. However, the fixing method of the positioning blocks cannot adopt the bolt and nut structure used by other components. Therefore, it is difficult to fix the positioning blocks on the rocker shaft. The traditional fixing method is cumbersome to operate, time-consuming and laborious, and has a large working intensity. Content of the Utility Model

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0014] It should be noted that like reference numerals and letters refer to like items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0015] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the figures, or the orientation or positional relationship in which the utility model product is customarily placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0016] The terms "first", "second", "third", etc. are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0017] The terms "parallel", "perpendicular", etc. do not mean that the components are required to be absolutely parallel or perpendicular, but can be slightly inclined. For example, "parallel" only means that its direction is more parallel relative to "perpendicular", and does not mean that the structure must be completely parallel, but can be slightly inclined.
