Periphery be equipped with annular groove, the end of the montant is stretched into annular groove.
Pilot hole using stepped hole as montant, can be in the ladder of stepped hole while montant moves in stepped hole
Spring is installed, cooperation annular slab uses so that montant is by the elastic force far from annular groove at variation.
Further, the quantity of the spring fixing portion can be individually or multiple, and single spring fixing portion is convenient
Processing, the fixed effect of multiple spring fixing portions is more preferable, and connection is more firm.
Further, the end of the montant is equipped with round end.Montant can be made to be easier to enter in annular groove using round end,
And montant will not damage the outer surface of metal tube because of friction.
Further, the periphery of the fixed section is equipped with external screw thread, and the fixed section periphery passes through external screw thread and spiral shell
Mother is fixedly connected.Screw thread on fixing end periphery can compress montant, and montant moves downward so that montant is stuck in annular groove.
Further, fixed section is additionally provided with tightening piece fixed part, and tightening piece fixed part is arranged in the end of metal tube and spring
Between fixed part, the tightening piece fixed part includes the through-hole being arranged on fixed section, and the end of the metal tube is equipped with tensioner
Block.
The tightening piece fixed part of use can utilize the fixed metal tube of plastic deformation and fixing end, can be squeezed from through-hole
Pressure tightening piece makes tightening piece be detached from from through-hole.
Further, the outer diameter of the fixed section is less than the outer diameter of thread segment.
Compared with prior art, the utility model has the beneficial effects that：
1) use spring fixing portion, when using the elastic force of spring nut being unscrewed from fixing end, montant straight up with
Annular groove is detached from, and when nut is tightly screwed in fixing end, montant stretches into annular groove, limits metal tube and the fortune of fixing end radially
It is dynamic.
2) tightening piece fixed part is used, is entered in through-hole after tightening piece fixed part plastic deformation, to make tensioner fix
Portion is disconnected with metal tube, and tightening piece is squeezed from through-hole.
