Surface, fastening spring lower end be supported on the upper surface of fastening ring set, the medial surface of fastening ring set be equipped with one week it is annular and
Cross sectional shape is arc-shaped card slot, is equipped with several matched sliding steel balls in card slot, every elastic claw item it is outer
The sliding slot being arranged along its length is equipped on side, the cross sectional shape of the sliding slot is and slides the matched arc-shaped of steel ball,
And the sliding steel ball in sliding slot and card slot corresponds；
The lower fixture includes fixing seat, compact heap, drive link and lifting linking member, and the fixing seat passes through its lower end
Support rod is fixed on bottom plate, is equipped with semicircular mounting groove on the medial surface of fixing seat, the mounting groove and fixing seat it is upper
End face connection on the medial surface of fixing seat and is located at the lower section of mounting groove equipped with the sliding shoe crossed out, the compression
The lower part of block be equipped with lateral direction penetrating and with the matched sliding eye of sliding shoe, compact heap by sliding eye be sleeved on sliding shoe simultaneously shape
At sliding pair, towards the pressure head crossed out is equipped on the side of mounting groove on compact heap, which is corresponding with mounting groove
And matched semi-cylindrical.
The drive link swung in vertical plane, the freedom of the drive link are hinged on the lateral surface of the compact heap
End is hinged on the upper end of lifting linking member, and the lower end of the lifting linking member runs through bottom plate vertically and forms the sliding pair slided up and down.
It is set with reset spring on the lifting linking member, the upper end of the reset spring is fixed in the middle part of lifting linking member laterally

The course of work and principle of the invention
Upper fixture clamps the nozzle at the straight tube end of copper pipe: the elastic claw item of the sleeve lower end of upper fixture is gradually sleeved on downwards nozzle
On, since the inside of elastic claw lower end is equipped with guiding incline, when it entangles the straight tube end of copper pipe, elastic claw item can be gradually swollen
It opens to promote to fasten ring set upward sliding, but since the effect of fastening spring makes the resistant effect of upward sliding of ring set,
And the bigger resistance of distending is bigger, to play the role of clamping, tube expansion formed punch moves down from the inside of sleeve and completes tube expansion,
When copper pipe needs to extract, sleeve is moved up, and lower end elastic claw distending is smaller and smaller, is finally restored to original state；
The U-shaped end of lower clamp copper pipe: the mounting groove being arranged in the fixing seat of lower fixture is matched with the U-shaped end of copper pipe, by copper
The U-shaped end of pipe is correspondingly placed in mounting groove vertically, pulls downward on lifting linking member, drive drive link then push compact heap to
Fixing seat moves closer to, and the pressure head on compact heap gradually protrudes into mounting groove, and the clamping that U-shaped is formed between mounting groove and pressure head is empty
Between, so that the copper pipe being placed in mounting groove be clamped, the drawing downward to lifting linking member need to be only removed after the completion of tube expansion work
The reset work of compact heap can be completed by the elastic force of reset spring for power.
