2nd, the utility model in fixed seat by setting arc groove, and connecting plate is rotated with the axle in arc groove and connected
Connect, be effectively reduced the damage to the base of carried bottom jack, the otic placode on fixed block is also configured to bi-lug plate, is hinged more
Firm, flexibility is stronger, while increases the lifting surface area between jointed shaft, and the abrasion to jointed shaft is small, increases jointed shaft
Intensity, it is more firm, achieve beneficial effect reasonable in design, safe and reliable；
3rd, the utility model fixes carried bottom jack by setting retainer ring between fixed cylinder and fixed seat in fixed cylinder
While, and fixed plus retainer ring, double insurance is formed, effectively prevents carried bottom jack stress from deviating from afterwards backward, is not easy partially
Tiltedly rock, it is more firm, and radially occupy little space, effectively solve the difficult problem in sealing bottom type base lift bottom, lift bottom effect
Fruit is good, achieves and occupies little space, safe and reliable beneficial effect.
