The specific embodiment:

The present invention is further described below in conjunction with accompanying drawing:

Shown in Fig. 1,2, support bar of the present invention is made of the mutual linking of the several sections bodies of rod 1, run through by elastic drag rope 2 between the body of rod and pull and support linking, and in two sections bodies of rod that are connected mutually, the cohesive end of first body of rod leaves socket 3, and the cohesive end of second body of rod is the Step Shaft 4 of bringing together, and this Step Shaft 4 just inserts and is embedded in the socket 3 of first body of rod; The epimere body of rod that is combined with handgrip is designed to the scalable body of rod, should comprise inner tube 5 and outer tube 6 by the flexible body of rod, the end of outer tube 6 is provided with tapered portion 61, and be provided with external screw thread 62 in corresponding site, one nut 7 that is socketed on inner tube 2 is connected external screw thread 62 and receives and press tapered portion 61, tapered portion 61 is shunk clamp inner tube 5.

Elastic drag rope 2 runs through and pulls and supports linking, and easy accessibility, quick only needs the two sections linking bodies of rod 1 that relatively stretch, and can realize that cohesive end separates and the folding support bar, thereby shorten support bar length, conveniently receives and keeps and carries.When needing to be connected, relieving is folding, and the cohesive end of two sections bodies of rod 1 is docked mutually, Step Shaft 4 just inserts and is embedded in the socket 3 of another body of rod, and under the effect of elastic drag rope 2, the body of rod of two sections linkings is combined closely in the axial direction, form a stock, i.e. support bar.

In the present embodiment, be combined with O shape ring 41 on the Step Shaft 4 end peripheries of second body of rod, utilize O shape ring 41, can well connect airtight the socket 3 of first body of rod, prevent from becoming flexible, improve the linearity that is connected.

The epimere body of rod that is combined with handgrip is designed to the scalable body of rod, can realize length adjustment like this.Pull out or indentation inner tube 5, the length of adjustable support bar is namely used height.Nut 7 is connected the external screw thread 62 of outer tube 6 by its internal thread, and keeps away the tapered portion 61 of pressing outer tube 6 ends by the bell of nut 7 inside, and make it to bring together and clamp inner tube 5, the position between firm inner tube 5 and outer tube 6, namely length adjustment is completed.

In the present embodiment, also have expander 8 to do inwall locking between the inner tube 5 of the epimere body of rod and outer tube 6; Utilize expander 8 spreading locking inwalls, outer wall clamps inner tube 5 by tapered portion 61 and nut 7, and stable connection, without being subject to position limitation, can realize the free-extension adjustment between inner tube 5 and outer tube 6 relatively.Outer tube 6 outer wall atresias, intensity is good, can not destroy structure, and atresia just can not rocked, good stability.

shown in Fig. 3 ~ 6, expander structure for one example of the present invention, mainly comprise a screw rod 81, a fusiform component 82 and an expanding component 83, screw rod 81 1 ends are provided with for the shaft part 811 that connects inner tube, fusiform component 82 is connected on screw rod 81 by its screwed hole 821, and fusiform component 82 peripheries are provided with two-stage expansion lug boss 822 vertically at least, expanding component 83 is constructed by halved body, and leave middle through hole, offer respectively splitting groove 831 vertically in the rear and front end of expanding component 83, cause expanding component 83 rear and front ends respectively jag be formed with several pieces expanding calvus, the calvus inside of corresponding front and back end is respectively equipped with the first bellmouth 832 and second bellmouth 833 of coaxial line, the first bellmouth 832 and the second bellmouth 833 are corresponding respectively coordinates expansion with the two-stage expansion lug boss of fusiform component 82, the halved body of expanding component 83 is pricked by elastic ring and is closed, and expanding component 83 wraps up fusiform component 82 just, external port place in the first bellmouth 832 of expanding component 83 is provided with interior ring step 834, an end that passes expanding component 83 in screw rod 81 arranges a locating part 812, locating part 812 support top expanding component 83 respective outer ends, one Metallic card 84 is connected on screw rod 81, and during assembling, Metallic card 84 is connected within expanding component 83 and encircles step, and Metallic card 84 limits expanding component 83 axial displacements together with locating part 812.

During use, the big end shaft part 811 of screw rod 81 is fixedly connected with in inner tube 5, and fusiform component 82 is sleeved on screw rod 81, and expanding component 83 halved body parcel fusiform components 82, and put elastic ring, pricked by elastic ring and close expanding component 83 halved bodies; Screw rod 81 other ends connect a locating part 812, play position-limiting action, prevent that expanding component 83 and fusiform component 82 break away from screw rod 81.Metallic card 84 is connected to the first interior interior ring step 834 of bellmouth 832 of expanding component 83, restriction expanding component 83 moves towards shaft part 811 directions, Metallic card 84 limits expanding component 83 axial displacements together with locating part 812, make thus expanding component 83 relative with screw rod 81 fixing, expanding component 83 can arbitrarily not move in use procedure.The two-stage expansion lug boss 822 of fusiform component 82 is positioned at expanding component 83 rear and front end the first bellmouth 832 and the second bellmouths 833 just, 82 liang of lateral plates 823 of fusiform component are arranged in the involutory section of expanding component 83 halved bodies just, but traveling priority, but can not rotate, thereby can realize the rotation of screw rod 81 is become the traveling priority of fusiform component 82.

Inner tube 5 is set in whole expander 8 in outer tube 6 mesopores, relatively rotate inner tube 5 and outer tube 6, utilize the threaded function of screw rod 81, fusiform component 82 axially moves forward along screw rod 81, at this moment the two-stage of fusiform component 82 expansion lug boss 822 is moved to small end by the first bellmouth 832 of expanding component 83 and the large end of the second bellmouth 833 respectively, front end calvus and the rear end calvus of realizing expanding component 83 open, thereby reach expanding component 83 rear and front end expansions, and with outer tube 6 inwalls frictions jams, inner tube 5 is fixedly connected with relatively with outer tube 6, completes linking.Relatively when revolution inner tube 5 and outer tube 6, can realize that the calvus of expanding component 83 front and back ends folds, at this moment inner tube 5 and outer tube 6 can be unclamped, realize the collapsing length adjustment, be convenient to collection, carry and use.

Fig. 7, shown in 8, the end that contacts to earth in support bar is provided with shock absorbing apparatus 9, shock absorbing apparatus 9 comprises that the first bar section 91(is one of them body of rod 1 of cane bar), the second bar section 92 and elastic drag rope 2, elastic drag rope 2 is through the first bar section 91, in the mesopore of the second bar section 92 and realize pulling and supporting and be connected the first bar section and the second bar section, be provided with interior step 911 in the hole among the first bar section 91, the interior Compress Spring 93 that arranges of tank 921 in the socket first bar section butt end of the second bar section 92, the first bar section 91 butt end docking Compress Springs 93, just make and form the relation of floating to axial between the second bar section 92 and the first bar section 91, the blocking point of laying on elastic drag rope 2 just with the first bar section 91 within step 911 clampings so that the first bar section is pulled to the second bar section during the elastic drag rope contraction.Compress Spring 93 support top the first bar section 91 and the second bar sections 92 realize axial float, obtain thus the shock-absorbing effect.

In the present invention, hold contacting to earth of support bar and also can suitably be provided with anti-vibration structure, thereby obtain desirable shock-proof effect, improve the comfortableness of using.
