The beneficial effects of the utility model are that pipe can rotate relatively with outer tube in the utility model made by stop collar, by outer pivoted housing and sheath interior pipe and outer tube was locked mutually, can satisfy the connecting rod spinfunction like this and can satisfy the function that connecting rod stretches again.The utility model is simple in structure, and is easy to make.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the exploded perspective view of the embodiment of the utility model telescoping tube.
Fig. 2 is the cutaway view of the utility model telescoping tube.
Wherein: 1, outer tube, 3, interior pipe, 5, sheath, 7, stop collar, 9, projection, 11, groove, 13, limited block, 15, first stopper slot, 17, the second stopper slots, 19, flexible member, 21, guide pad, 23, gathering sill, 25, outer pivoted housing, 27, the outer ring.
The specific embodiment
Shown in Fig. 1-2, a kind of telescoping tube of electric tool, comprise outer tube 1, insert interior pipe 3 in the outer tube 1, with the sheath 5 that interior pipe 3 flexibly connects, this telescoping tube also comprises stop collar 7, stop collar 7 flexibly connects with sheath 5, and stop collar 7 and sheath 5 have latch-up structure at circumferencial direction.Latch-up structure comprises having a projection 9 on the stop collar 7 at least, has two grooves 11 on the sheath 5 at least, and projection 9 stretches into groove 11 and realizes stop collar 7 and sheath 5 locking in a circumferential direction.Stop collar 7 is provided with limited block 13, and limited block 13 is fixedlyed connected with outer tube 1.Wherein, have first stopper slot 15 on the stop collar 7, limited block 13 is moved in first stopper slot 15 vertically along axis direction.Also be provided with flexible member 19 on the stop collar 7, flexible member 19 provides restoring force for limited block 13 at axis direction.In addition, sheath 5 is provided with second stopper slot 17 along sheath 5 circumferencial directions, and limited block 13 is along the circumferential direction rotated in second stopper slot 17, and the along the circumferential direction rotating angle of second stopper slot 17 is 0 degree～180 degree.Because sheath 5 inwalls have guide pad 21, interior pipe 3 outer walls have gathering sill 23 along axis direction, and guide pad 21 embeds gathering sill 23.Be with outer pivoted housing 25 on the sheath 5 and be connected with outer pivoted housing 25, and the front end outer wall of sheath 5 compresses with the front inner wall of outer pivoted housing 25 and all cooperates with the inclined-plane with screw thread.Be convenient to fixedly flexible member 19 and limited block 13, so be fixedly connected with outer ring 27 at the outer wall of stop collar 7.This electric tool can be grass-mowing machine, bar chain saw, bar shrub and hedge trimmer etc.
When the operator need stretch telescoping tube, at first outer pivoted housing 25 is rotated away from sheath 5, the sheath 5 front end outer walls and the front inner wall of outer pivoted housing 25 are unclamped, can relatively move with outer tube 1 until interior pipe 3, owing to have gathering sill 23 vertically on the interior pipe 3, pipe 3 can move axially along guide pad 21 then, when reaching the length of operator's needs, the operator rotates outer pivoted housing 25 near sheath 5, compress the locking of pipe 3 and outer tube 1 in then realizing until the front inner wall of sheath 5 front end outer walls with outer pivoted housing 25.
When the operator need be with interior pipe 3 during with outer tube 1 relative rotation, outer ring 27 is moved along the direction away from sheath 5, thereby driving stop collar 7 moves axially at first stopper slot 15 along limited block 13, leave groove 11 on the sheath 5 until the projection on the stop collar 79, stop collar 7 can be rotated relatively with sheath 5.Then, stop collar 7 is rotated at circumferencial direction, drives limited block 13 and rotates at circumferencial direction along second stopper slot 17, because limited block 13 is fixedlyed connected with outer tube 1, thereby outer tube 1 is also followed limited block 13 and is moved at circumferencial direction, thus pipe 3 and the relative rotation of outer tube 1 realization in realizing.When rotating to the angle of operator's needs, the operator unclamps outer ring 27, because the restoring force effect of flexible member 19, flexible member 19 promotes stop collar 7 and moves to sheath 5 directions, projection 9 on the limited block 13 is inserted in the groove 11, pipe 3 and the locking of outer tube 1 in realizing at circumferencial direction.
Should be appreciated that foregoing description only is in order to set forth the present invention.Those skilled in the art can make multiple replacement form and modification without departing from the invention.Therefore, the invention is intended to all these replacement forms, modification and modification is included in the protection domain of appended claims.
