Described eccentric shaft is made up of interior axle, eccentric block set, outer shaft and eccentric upper shield that order fuses, in axle diameter and the internal diameter of interior pipe is suitable and be fixedly linked with interior pipe, the diameter of eccentric block set greater than the diameter of interior axle and with concentric linking to each other of interior axle, the diameter of outer shaft links to each other less than the diameter of interior axle and with eccentric block set is eccentric, the slightly larger in diameter of eccentric upper shield links to each other in the diameter of outer shaft and with outer shaft is concentric, and described eccentric bushing activity is nested on the outer shaft and by eccentric block set and eccentric upper shield is located.
Described eccentric bushing is the elastic opening structural member, and the diameter of the eccentric block set on its external diameter and the eccentric shaft is suitable, and the diameter of its trepanning and the diameter of the outer shaft on the eccentric shaft are suitable, and its opening is arranged on a thicker side of the collar.
The outer wall of described eccentric bushing is provided with the gear shape anti-skid structure.
Also comprise an anti-sliding sleeve, this anti-skidding cover is connected the mouth of pipe of outer tube, and the nose end bread of outer tube is firmly formed a fore shaft, and this fore shaft can prevent that interior pipe and the eccentric lock mechanism integral body that is connected thereof from skidding off from outer tube.
Flexible pipe structure of the present invention is simple, and is in light weight, is easy to carry.The two ends of telescopic pipe can connect the device of multiple different purposes, form the expansion bend of multiple different purposes.

Embodiment
Referring to Fig. 1, telescopic pipe of the present invention comprises outer tube 1, interior pipe 2, eccentric lock mechanism 3 and anti-sliding sleeve 4.Interior pipe 2 stretches in the outer tube 1 and can move along outer tube wall, the external diameter of interior pipe 2 is slightly less than the internal diameter of outer tube 1, eccentric lock mechanism 3 is made up of eccentric shaft 31 and the eccentric bushing 32 that is nested on this eccentric shaft, the inner of eccentric shaft 31 is connected the front end that stretches into the interior pipe 2 in the outer tube 1, eccentric shaft 31 can move and rotate with interior pipe, and eccentric bushing 32 activities are nested in the outer end of eccentric shaft and can closely contact to link to each other with outer tube and form locking.Anti-sliding sleeve 4 is connected the mouth of pipe of outer tube 1, and the nose end bread of outer tube is firmly formed a fore shaft, can prevent that interior pipe 2 and eccentric lock mechanism 3 integral body that connected thereof from skidding off from outer tube.
Referring to Fig. 2, Fig. 3, eccentric shaft 31 among the present invention is made up of interior axle 311, eccentric block set 312, outer shaft 313 and eccentric upper shield 314 that order fuses, in the internal diameter of axle 311 diameter and interior pipe 2 suitable and be fixedly linked with interior pipe 2, present embodiment is to connect (cooperating referring to Fig. 1) by bearing pin 5, the diameter of eccentric block set 312 greater than the diameter of interior axle 311 and with concentric linking to each other of interior axle, the diameter of outer shaft 313 links to each other less than the diameter of interior axle 311 and with eccentric block set 312 off-centre, and the slightly larger in diameter of eccentric upper shield 314 links to each other in the diameter of outer shaft 313 and with outer shaft is concentric.Eccentric bushing 32 activities are nested on the outer shaft 313 and by eccentric block set 312 and eccentric upper shield 314 and are located.
Referring to Fig. 4, Fig. 5, eccentric bushing 32 among the present invention is the elastic opening structural member, the diameter of the eccentric block set 312 on its external diameter and the eccentric shaft is suitable, and the diameter of its trepanning 321 and the diameter of the outer shaft on the eccentric shaft 313 are suitable, and its opening 322 is arranged on a thicker side of the collar.Outer wall at eccentric bushing is provided with gear shape anti-skid structure 323.
The working principle of telescopic pipe of the present invention can be described as follows in conjunction with Fig. 6, Fig. 7:
During release, the degree of eccentricity complementation of eccentric shaft 31 and eccentric bushing 32, form assembled state as shown in Figure 6, be eccentric bushing 32 just integral seat drop on the eccentric block set 312 of eccentric shaft, eccentric bushing 32, eccentric block set 312 and interior axle 311 threes form concentric combination, the eccentric lock mechanism 3 of pipe 2 and connection thereof can move freely in outer tube 1 together in this moment, stretches.
Flexible when needing position and lock when finishing, then by pipe 2 in the rotation, drive eccentric shaft 31 by interior pipe 2 and rotate an angle, form assembled state as shown in Figure 7, to be eccentric bushing 32 promoted by the eccentric outer shaft on the eccentric shaft 31 313 and protrude to a side, one side of this protrusion surpasses the border of eccentric block set 312, make after 312 combinations of eccentric bushing 32 and eccentric block set size greater than wherein either party, link to each other with tight conflict of inwall of outer tube, thereby pipe 2 forms locking with respect to outer tube 1 in making, and can not move easily.
