So, often by the elastic force pressure of spring 47, as shown in figure 12, with handle member 41 left direction suppress, and be connected under the aspect of the 40a of wall portion of rake 40 of retaining member 33 position of restrictions handle member 41 with the 45a of the wall portion retaining of the rake 45 of handle member 41.At this moment, the pin 38 that is contained in recess 42 is to be tilted the 40a of the wall portion pushing of portion 40 and to move to the direction of window 39, and steps up the rake 45 of handle member 41, charges into arbitrary engaging ditch 9 to interior pipe 2 from window 39, and steps up the flat of handle member 41.
Thus, pin 38 is to be fixed between handle member 41 and the retaining member 33, makes pin 38 link the window 39 of retaining member 33 and the ditch that engages of interior pipe 2, and therefore interior pipe 2 promptly is fixed under this state.Again because of the edge portion 34 of retaining member 33 is connected to the segment difference section 1a of outer tube 1 via stopper element 36 and liner 35 retainings, and opposition side is that the covering member 31 that mat is fixed in outer tube 1 is closed, so retaining member 33 is the openends that are fixed in outer tube 1.Thus, interior pipe 2 is via retaining member 33, and pin 38 and handle member 41 are fixed in outer tube 1.
From this state, when the elastic force pressure that handle portion 46 is being revolted spring 47 moved to the direction of covering portion member 31 of outer tube 1, then the flat of handle member 41 broke away from from window 39, and recess 42 is promptly below window 39, therefore sell 38 and promptly come off, slide rake 45 and move to recess 42 by window 39.
By this, the stationary state of interior pipe 2 promptly is disengaged, therefore, and pipe 2 in can sending from outer tube 1, and interior pipe 2 can be inserted in outer tube 1, the overhang that pipe 2 is given prominence to from outer tube 1 in can adjusting.
As mentioned above in the present embodiment, because handle portion 46 is integrally formed in handle member 41, can reduces the number of spare parts of operating portion 5, and can reduce the cost, and can improve assembling.The structure of operating portion 5 becomes simple, and compares when constituting operating portion 5 with most parts, positively commence operation.
Owing to connect airtight the 45a of wall portion of the rake 45 of the 40a of wall portion of rake 40 of retaining member 33 and handle member 41, therefore be contained in the pin 38 of recess 42, become from recess 42 step up rake 45 and reach till the window 39 during the motion of pin 38 to become polar circle sliding, can avoid when the turnover operation of interior pipe 2, feeling having the improper phenomenon of resistance etc.
Because of with handle portion 45 same side spring 47 being set, the elastic force pressure of mat spring 47 can prevent with the motion of pin 33 as fulcrum twist grip member 41 grades again.
Now the example with the distribution mechanism of present embodiment is shown in Figure 19 to 22.
In an end of coil tension spring 10,11, be connected with the lead 14 of the Wiring construction element that becomes linking part 4,15 a wherein side end, and in the other end of coil tension spring 10,11, be connected with the lead 52,53 of connector contact member 51 of a key element of the Wiring construction element that becomes linking part 6.
The coil tension spring 10,11st of the main distribution mechanism of pipe 2 in constituting is as Figure 20 (a), (b), (c) shown in, the appearance and size of its central portion forms than cylindrical portion 16a, the size that the internal diameter of 16b is slightly little, and its both ends dwindle gradually and make outermost end form the pushing and drawing shape that continuous most turning minor diameter part is become, and a final circle of end is to curve to hold up 90 degree, connects lead 14 and constitute, 15,52,53 used shackle 10a, 10b, 11a, 11b.Again, lead 14,15,52,53rd is entangled in shackle 10a, 10b, and 11a behind the 11b, fixes with scolding tin.
Again, connector contact member 51 and be connected in the shackle 10b of the coil tension spring 10,11 of this connector contact member 51, the end of 11b side is as shown in figure 21, is contained in the lead covering portion 55 of the insertion opening that is formed with connector 29.
