There is piston rod, fluted a opened up in the leading section of piston rod, groove a is detachably connected with tube expander by return pull bar,
The rearward end of tube expander is located in the body of guide pipe；The rearward end of the return pull bar radially offers annular groove,
The leading section of piston rod is provided with the spacer pin with spring, and the spacer pin is against in the annular groove under the action of the spring,
The rear of annular groove offers at least one and moves back cotter way from what annular groove was exited for spacer pin vertically.
In above-mentioned tube expander and sliding sleeve tightener Quick Connect Kit, the groove width L of the annular groove is more than described
The cross-sectional width H of spacer pin in the longitudinal direction.
It is described to move back that cotter way has two or more and its is equal in above-mentioned tube expander and sliding sleeve tightener Quick Connect Kit
It is even to be distributed on the excircle in return back end of tie rod portion.
In above-mentioned tube expander and sliding sleeve tightener Quick Connect Kit, the cotter way that moves back is with two.
In above-mentioned tube expander and sliding sleeve tightener Quick Connect Kit, the least significant end of the return pull bar is provided with slope
Spend angle θ.
In above-mentioned tube expander and sliding sleeve tightener Quick Connect Kit, the spacer pin with spring passes through nut lock
Tightly in the leading section of piston rod.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：When in use, in the front end of piston rod
Portion's upper tube expander of connection can carry out pipe expanding, convenient to disassembly, make tube expanding function and tighten up function to be integrated in one, and make work
Has the convenience of cost reduction, lifting carrying and operation.
