At this time, the axis L1 of the rod body 50 forms an angle θ1 with the central axis L2 of the through hole 21.

Similarly, when the adjusting block 60 is located at the second position P2, as shown in FIG. 4A, if the operator applies an external force in the Y-axis direction to move the rod 50, the rod 50 will also be in the through hole 21 The inner left and right yaw (as shown in FIG. 4B), when the rod 50 is biased to the limit, as shown in FIG. 4B, the small diameter portion 653 of the adjusting block 60 abuts against the hole edge of the through hole 21. 211. At this time, the axis L1 of the rod 50 forms an angle θ2 with the central axis L2 of the through hole 21, and the angle θ2 is greater than the angle θ1. In other words, as shown in FIG. 3B and FIG. 4B, when the adjustment block 60 is located at the first position P1, when the adjustment block 60 is located at the second position P2, the rod 50 may have a larger The yaw limit.

Therefore, the operator can make the rod 50 have a yaw limit of a minimum/maximum amplitude by changing the position of the adjustment block 60 (at the first/second position P1, P2). Moreover, due to the push-out body portion 55 of the adjustment block 60, the operator can make the rod body 50 different by placing the adjustment block 60 at any position between the first and second positions P1, P2. The yaw limit of the amplitude.

In addition, as shown in FIG. 5, in the rocker 10 of the limitable stroke of the present invention, a fixing means 70 for fixing the adjusting block 60 to the rod 50 may be further included. In detail, the fixing means 70 may be a meltable material or an extrudate, and the foregoing meltable material may be, for example, a solder, a plastic, a candle or the like, and an example of the foregoing adhesive may be as Adhesive, resin or the like. So, the operator can melt The molten material or the extrudate covers the junction of the adjustment block 60 and the rod 50 to fix the position of the adjustment block 60, thereby maintaining the rod 50 at a desired yaw limit. It is avoided that the position of the adjusting block 60 is moved by repeatedly pushing the rod 50, and the yaw limit of the rod 50 is changed.

In summary, since the rocker 10 of the limitable stroke of the present invention has an adjustment block 60 axially displaceable along the shaft 50, the rod can be adjusted by changing the position of the adjustment block 60 according to actual needs. The limit of the yaw in the perforation 21 is such that the rod 50 can be deflected with a small or large amplitude. Therefore, the rocker 10 of the present invention which can limit the stroke has high practicability. Further, since the adjustment block 60 has a push-up configuration, the rod body 50 can also have a yaw limit of a different magnitude. Moreover, the rocker 10 of the limitable stroke of the present invention can also fix the position of the adjusting block 60 through the fixing means 70, thereby avoiding changing the yaw limit of the rod 50.
