Shape is consistent with the shape of first gap, and the lower semisection of piston adjustment axle is in the inside of the piston, and its upper semisection is naked
It is exposed at the upper end of the piston.
Also include being arranged on the axle sleeve on the piston adjustment axle top, the axle sleeve is wrapped in the top that the piston adjusts axle
End, is provided with small locking nut below the axle sleeve, and the small locking nut has two, adjusts axle positioned at the piston respectively
Both sides, be provided with adjustment swivel nut below the small locking nut, the adjustment swivel nut be two, respectively positioned at the piston
Adjust the both sides of axle.
Further technical scheme of the invention is that big locking nut is provided with above the bearing, the big locking screw
Mother has two, and it is cylindrical structural, and the big locking nut is located at the both sides that the piston tightly adjusts axle respectively.In the piston
Locking nut is provided with the right side of adjustment axle, the locking nut is fixed on the upper end of the piston by rotation, and in the locking
Clamping screw is connected with nut, the clamping screw is used in combination with the locking nut.The piston adjustment axle lower semisection
Length is the height and the piston upper end thickness sum of the internal piston hollow-core construction.
The advantage of the invention is that:The piston retention mechanism adjusts axle to adjust the length of internal piston cavity by piston
Degree, so as to produce different power when ensureing that connecting rod rotates up and down, improves operating efficiency, and the piston retention mechanism passes through lifter plate
The height of piston can be adjusted, facilitates operating personnel to use in a variety of contexts.
