The built-in float pinrod comprises a hard and a soft slide rod, and moves only in the hollow holding handle, the bending spring, and the hollow casing for the rod body.
In some cases the small end of the rod is clamped to the pin or has a bushing in it to allow the pin and rod oscillation.
在一些情况下，连杆小端夹定在活塞销上或在连杆里有一套管，这样可以使得活塞销与连杆能够共同摆动。
