And make circular hole inner ring surface and the complete buckle-like of outer shroud of corrugated tube A21 (inner or left end) that end socket 5 end face arranges, make end socket simultaneously
5 outer faces become vertical flush state with (the inner or left end) of corrugated tube A21, and the inner ring surface then utilizing end socket 5 central bore is pre-
The groove (groove is to open outside 30 degree of angles, i.e. left side chamfering, such as Fig. 5) first set makes the interior of end socket 5 endoporus by welding manner
Anchor ring is welded and fixed firmly with the outer ring surface of corrugated tube A21 (inner or left end)；Then corrugated tube C17 (outer end or right-hand member) is overlapped
It is anchored to the indent (left low right high stepped outer shroud, such as Fig. 9) that frame member A9 inner end outer shroud is arranged, and passes through welding manner
Corrugated tube C17 (outer end or right-hand member) and frame member A9 is made to be welded and fixed firmly；Include end socket 5, corrugated tube A21, short circuit at this moment
The tubular flexibility that head A20, corrugated tube B19, short circuit head B18, corrugated tube C17 and frame member A9 define an axially deformable is whole
Body, hereinafter referred to as (tubular flexibility is overall)；As shown in structural representation Figure 13.
3rd step (Figure 14): this (tubular flexibility is overall) is overlapped with steel ball C6 and steel ball D8 in being anchored to outside inner tube 12
The appointment position in portion, and make corrugated tube A21 (inner or left end) outer shroud be anchored to reducer pipe D section 22 with one end set of end socket 5
Place, and by welding connecting mode, end socket 5 is pre-with (outer end or right-hand member) outer ring of reducer pipe C section 24 near the outer end of internal ring
It is welded and fixed at the groove being first provided with firmly；Then pass through welding connecting mode and utilize corrugated tube C17 (inner or left end) integrally
With the outer end of frame member A9 inside the groove that arranges frame member A9 is weldingly fixed on the appointment position of inner tube 12 outer shroud；
(as shown in structural representation Figure 14).
Being the formation of inner tube 12 (inner or left end) at this moment can be at reducer pipe D section 22, reducer pipe C section 24 and reducer pipe
The inner side of B section 25 is with this (tubular flexibility is overall) corresponding structure of carrying out left and right shift reciprocately coaxial with reducer pipe A section 1；Need
Illustrate is to make this inner tube 12 of reduction (stretch in the inner side of reducer pipe D section 22, reducer pipe C section 24 and reducer pipe B section 25
Frictional resistance when contracting or left and right displacement), the inner side of this reducer pipe D section 22, reducer pipe C section 24 and reducer pipe B section 25 and inner tube 12
The gap that 2-4mm does not waits it has been reserved with between outer ring surface；This reducer pipe C section 24 includes setting inside short circuit head A20 and short circuit head B18
A plurality of steel ball A2 of putting, combination seal 3, steel ball B4, steel ball C6, steel ball D8 and inner tube 12 outer shroud in encircling contact shape,
The structure of rolling friction it is when inner tube 12 carries out (flexible or left and right displacement) deformation with this (tubular flexibility overall), but not
Mistake axiality controls；
4th step (Figure 15): by outer annular recess with a plurality of steel ball E10 and end face with the frame of a plurality of struts 14
Component B16 set is anchored to the appointment position of inner tube 12 outer shroud, refers to the structural representation of Fig. 1；Then by trocar sheath 7 from frame member B16
One end start to overlap the outside being anchored to the parts such as frame member B16, corrugated tube C17, corrugated tube B19 and corrugated tube A21 the most successively, and
Make one end (or left end) of trocar sheath 7 close to end socket 5 the inner (termination of the horizontal ends of right angle arcuate structure) in the outer part, simultaneously
The corresponding groove utilizing both terminations to pre-set by the way of being welded to connect carries out being welded and fixed firmly；Then will
The slope that the inner side of the other end (or right-hand member) of trocar sheath 7 is arranged with the outer shroud of frame member B16 outer end by the way of being welded to connect
Mouth is welded and fixed；(as shown in structural representation Figure 15).
