Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is clearly and completely described.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
As shown in Figure 1, the adjustable valve rocker of specification in the utility model, including rocker body 1, rocker body 1, which has, to be pushed away
Bar interconnecting piece and valve interconnecting piece, push rod interconnecting piece include push rod link block 2 and the first adjusting screw rod 4, and the one of push rod link block 2
End opens up push rod ball-and-socket 3, and the other end is threadedly coupled with rocker body 1 by the first adjusting screw rod 4；Valve interconnecting piece includes that valve connects
Block 5 and the second adjusting screw rod 6 are connect, one end of valve link block 5 is set there are two reinforcing rib 7 is limited, and valve can be fastened in two limits
Between the reinforcing rib 7 of position, the other end is threadedly coupled with rocker body 1 by the second adjusting screw rod 6.
The assembling process of the utility model is as follows:
Adjusting screw rod is connected through a screw thread with rocker body 1, and rotating push rod interconnecting piece and valve interconnecting piece make adjusting screw rod exist
