Further, the outer wall of inner sleeve 2 has multiple the first inserted part 12 axially arranged along it; Limited part 5 comprise can along outer sleeve 1 move radially with can with the first inserted part 12 clamping or the second inserted part be separated, extension and contraction control seat 8, by the flexible pressure ring 9 of bolt 11 stationary gland on extension and contraction control seat 8 and be located between flexible pressure ring 9 and extension and contraction control seat 8 for regulating the adjusting portion of the second position, inserted part, second inserted part is located between adjusting portion and extension and contraction control seat 8, and wherein extension and contraction control seat 8 has the center hole 10 through with outer sleeve 1.As shown in Figure 4 and Figure 5, the cross section of the extension and contraction control seat 8 in the present embodiment is circular, and its global shape is approximate in funnel-like.Flexible pressure ring 9 coordinates gland on one end that extension and contraction control seat 8 cross sectional area is larger by many bolts 11.Wherein, above-mentioned many bolts 11 arrange a circle along the outer rim of the endoporus of flexible pressure ring 9 respectively.
Particularly, continue shown in composition graphs 2 and Fig. 6, the first inserted part 12 is for being opened in the wedge slot on inner sleeve 2 excircle, and namely this wedge slot is ring.Second inserted part is that multiple flexible fixture block 13 (is only described for three flexible fixture blocks 13 in the present embodiment, certainly more flexible fixture block 13 also can be set), this flexible fixture block 13 is provided with straight pin 17 towards the side of flexible pressure ring 9, extension and contraction control seat 8 has the mounting groove 16 (mounting groove 16 in the present embodiment is three, respectively with above-mentioned three flexible fixture block 13 one_to_one corresponding) for installing each flexible fixture block 13 respectively that multiple radial direction along inner sleeve 2 is arranged.Each mounting groove 16 is uncovered towards the side of inner sleeve 2, that is, mounting groove 16 side is communicated with the center hole 10 of extension and contraction control seat 18, and the one side of each flexible fixture block 13 corresponding mounting groove 16 closed side (side relative with its open-position-side) is provided with spring 14.When flexible fixture block 13 is installed in corresponding mounting groove 16, its spring 14 abuts with the closed side of mounting groove 16.When spring 14 is in compressive state, in flexible fixture block 13 retraction mounting groove 16 not with wedge slot clamping; When spring 14 drives flexible fixture block 13 to move to make its side not being provided with spring 14 stretch out mounting groove 16 and then stretch in wedge slot, with wedge slot clamping to the direction near inner sleeve 2 by its elastic force effect.
Each flexible fixture block 13 in the present embodiment is provided with two springs 14 all side by side, certainly also only can arrange a spring 14, or arranges multiple spring 14.The shape of mounting groove 16 preferably rocks displacement to avoid flexible fixture block 13 with the form fit of flexible fixture block 13 in mounting groove 16, affects the contact clamping of itself and wedge slot.As shown in Figure 5, the plurality of mounting groove 16 is uniformly distributed along the outer rim of the center hole 10 of extension and contraction control seat 8 respectively, can make when flexible fixture block 13 is with a wedge slot phase clamping on inner sleeve 2 like this, multiple flexible fixture block 13 can be close to and surround this wedge slot, to make this wedge slot circumference uniform force and then to make the more firm of the two clamping.
Preferably, flexible fixture block 13 is rectangular block, and the shape that each flexible fixture block 13 is not provided with the side of spring 14 is inserted in wedge slot with wedge slot form fit coordinating, that is, make flexible fixture block 13 can be meshed with wedge slot, increases clamping dynamics.Wherein, the angle of wedge of above-mentioned wedge slot is towards the first end of inner sleeve 2, can only move outside outer sleeve 1 with the inner sleeve 2 when not rotating extension and contraction control plate 15 (will introduce in detail below), and can not move in outer sleeve 1, and then when flexible rod of the present invention is applied in object support, provide support force that is stable and that continue.
Further, adjusting portion is can around the extension and contraction control plate 15 of the axial rotation of outer sleeve 1.As shown in Figure 4, extension and contraction control plate 15 has the through hole 18 passed for inner sleeve 2, multiple the first pilot hole 19 supplying the straight pin 17 of each flexible fixture block 13 to wear respectively and the second pilot hole 20 worn for bolt 11.The plurality of first pilot hole 19 is arranged according to the position of each straight pin 17 respectively, multiple second pilot hole 20 is arranged according to the distributing position of bolt 11 respectively, the quantity of the second pilot hole 20 in the present embodiment is equal with the quantity of bolt 11, and one_to_one corresponding is arranged, and also can wear many bolts 11 in certainly each second pilot hole 20.Rotate extension and contraction control plate 15 or when inner sleeve 2 moves outside outer sleeve 1, each bolt 11 slides along the second pilot hole 20 of correspondence, each straight pin 17 along the first pilot hole 19 of correspondence slide to drive each flexible fixture block 13 along inner sleeve 2 move radially so that with corresponding wedge slot clamping or be separated.
Continue shown in composition graphs 4, the first pilot hole 19 and the second pilot hole 20 are the arc-shaped hole that the periphery along through hole 18 is arranged.Further, first pilot hole 19 reduces gradually to the direction away from inner sleeve 2 from its one end in the radial direction of inner sleeve 2, its two ends are made to form stub end and little head end respectively, namely the distance of this stub end and little head end distance inner sleeve 2 is not etc., relatively little head end is closer to inner sleeve 2 (namely in the radial direction of inner sleeve 2 for this stub end, the first pilot hole 19 in the present embodiment is approximately wedged hole, specifically refer to Fig. 4, certainly, first pilot hole 19 also can be other shape, as long as its two ends have spacing in the radial direction of extension and contraction control plate 15).When extension and contraction control plate 15 rotates and drives straight pin 17 to slide towards this little head end, flexible fixture block 13 moves to be separated (now flexible fixture block 13 extrusion spring 14 with the first inserted part 123 along the radially outward of inner sleeve 2, and the movement of flexible fixture block 13 realizes by artificially rotating extension and contraction control plate 15, or push away realization by the crowded of inner sleeve 2 towards the direction movement away from outer sleeve 1), and then inner sleeve 2 can be moved relative to outer sleeve 3, such as make inner sleeve 2 be reset to its initial position; And straight pin 17 when sliding towards this stub end under the elastic force effect of spring 14, flexible fixture block 13 radially-inwardly moving so that (now spring 14 resets with the first inserted part 3 clamping along inner sleeve 2, if when now extension and contraction control plate 15 does not have other External Force Actings, extension and contraction control plate 15 can rotate under the drive of Returnning spring 21, this Returnning spring 21 will introduce below), thus inner sleeve 2 and outer sleeve 1 relative position are fixed.The object namely the first pilot hole 19 being set to not wait with the distance between inner sleeve 2 respectively at two ends be in order to when inner sleeve 2 moves relative to outer sleeve 1 can guide extension fixture block 13 to away from or the direction of close inner sleeve 2 move.And the setting of extension and contraction control plate 15 is for when the inner sleeve 2 being in spacing state for moving in outer sleeve 1, rotation by extension and contraction control plate 15 self slides into the little head end of this pilot hole to drive the straight pin 17 of each flexible fixture block 13 along the first pilot hole 19 of correspondence, each flexible fixture block 13 is separated with wedge slot and thinks that the movement of inner sleeve 2 provides space.
Extension and contraction control plate 15 in the present embodiment is circular plate (certainly also can be the plate of other shape), its radius is greater than the radius of flexible pressure ring 9 and extension and contraction control seat 8, namely its outer rim protrudes flexible pressure ring 9 and extension and contraction control seat 8, so that user rotates extension and contraction control plate 15.
Preferably, adjusting portion also comprises and being located between flexible pressure ring 9 and extension and contraction control plate 15 for the Returnning spring 21 of the extension and contraction control plate 15 that resets and in circular guidance tape 22.This Returnning spring 21 is torsion spring, and its one end is connected with flexible pressure ring 9, and the other end is connected with extension and contraction control plate 15, specifically on flexible pressure ring 9 and extension and contraction control plate 15, can arrange spliced eye respectively.Particularly, when flexible fixture block 13 is with wedge slot clamping, Returnning spring 21 is in just torsion state; When rotating extension and contraction control plate 15 and making flexible fixture block 13 move in mounting groove 16, spring 14 forced compression of flexible fixture block 13, Returnning spring 21 produces moment of torsion further, when cancellation puts on the external force of extension and contraction control plate 15, extension and contraction control plate 15 rotates backward by the elastic force of Returnning spring 21, and simultaneous retractable fixture block 13 moves to the direction away from mounting groove 16 by the restoring force of its spring 14.Guidance tape 22 is located in the through hole 18 of extension and contraction control plate 15, and its side towards extension and contraction control seat 8 is posted by extension and contraction control seat 8, and the setting of this guidance tape 22 is the rotations for limiting inner sleeve 2, prevents inner sleeve 2 from shaking when moving along its axis.In order to better fixed guide band 22, also special in the present embodiment the restraining groove 24 of a circle for the annular of spacing guidance tape 22 is set on extension and contraction control seat 8.
During specific operation, by pulling the first link 3 to be extracted out by inner sleeve 2, in the process of withdrawing inner sleeve 2, the crowded thrust that the flexible fixture block 13 of limited part 5 was subject to inner sleeve 2 before this makes it move in mounting groove 16, namely flexible fixture block 13 moves to notch direction until be separated with wedge slot towards the side of inner sleeve 2 gradually along the inclined-plane of wedge slot, now flexible fixture block 13 abuts towards the side of inner sleeve 2 with the outer surface of inner sleeve 2, namely abut with the part of inner sleeve 2 between adjacent two wedge slots, continuation along with inner sleeve 2 moves, next wedge slot moves to the open-position-side opposite position with each mounting groove 16, now each flexible fixture block 13 moves until both are meshed to reach the effect of spacing inner sleeve 2 to this wedge slot by the elastic force of its spring 14.When making the inner sleeve 2 being in spacing state move in outer sleeve 1, such as, when needing shortening inner sleeve 2 to be positioned at the length outside outer sleeve 1, rotatable extension and contraction control plate 15, making it pass through to promote straight pin 17 drives flexible fixture block 13 to move in mounting groove 16 along the slip of the first pilot hole 19 of correspondence, and then each flexible fixture block 13 is separated with corresponding wedge slot, think that the movement of inner sleeve 2 provides sliding space.When inner sleeve 2 is adjusted to desired location place, unclamp extension and contraction control plate 15, extension and contraction control plate 15 resets under the drive of Returnning spring 21, simultaneously each flexible fixture block 13 resets under the effect of its spring 14 and extension and contraction control plate 15, namely, engage with corresponding wedge slot, complete the spacing of inner sleeve 2.
