The assembly is characterized in that a thread head of the extension hard shaft is screwed into a thread head of the extension connecting shaft, the extension hard shaft support and the spacer sleeve are respectively sleeved on the extension hard shaft, a support sleeve is embedded into the extension aluminum pipe, the extension connecting sleeve is sleeved on the extension aluminum pipe, and a positioning screw of the extension connecting shaft is inserted into a positioning hole in the extension aluminum pipe. The extension rod assembly manufactured by the technical scheme is convenient to use, so that the clip operational range of garden machines is increased, the use of other assistant tools is reduced, and the work efficiency of operators is remarkably improved.

Description

A kind of extension rod combination

Technical field

The utility model relates to the graden machine field, particularly a kind of segmented extension rod structure.

Background technology

At present, averruncator, minute segmentation graden machine such as Gao Zhiju adopts two sections combinations, the aluminum pipe combination of cutting head part namely, the aluminum pipe combination of rear engine part, the graden machine that forms different purposes, two sections middle syndetons that do not have extension function of facility, because its active length is limited in scope, when long-pending broad and highly higher gardens crop is pruned operation over there, also need by increasing some aids such as instrument, not only brought inconvenience to practical operation, operating efficiency is low, and operation effectiveness is poor, has also increased the potential safety hazard when pruning operation, therefore, be badly in need of a kind ofly can pruning operation by broad and highly higher gardens crop to area, operating efficiency is high, and operation effectiveness is good, the gardens Work machine that security is good.

The utility model content

The purpose of this utility model provides a kind of extension rod combination, be used for being connected to the centre of segmented facility, increased the entire length of facility, increased the pruning job area of minute segmentation graden machines such as averruncator, Gao Zhiju, this extension rod combining structure belongs to segmented, can carry out according to actual needs many group assemblings, be connected firmly, reliably, accurate positioning, dismounting is simple and easy, easy to carry, greatly improved operating efficiency and security.

The technical scheme that the utility model is taked is:

The combination of a kind of extension rod is by Hose Jacket, prolong that hard axle, interstage sleeve, the hard axle of prolongation support, prolong aluminum pipe, prolong the adapter sleeve combination, couple-extended shaft forms; It is characterized in that: the hard axle of described prolongation two ends are respectively equipped with square spigot, thread head; Described couple-extended shaft two ends are respectively equipped with square hole in screwed hole and the couple-extended shaft, and described thread head screws in the screwed hole; The hard axle of described prolongation supports and comprises oiliness bearing and cover support set externally, and oiliness bearing and interstage sleeve all are sleeved on and prolong on the hard axle, and support set is inlaid in the described prolongation aluminum pipe; Described prolongation adapter sleeve is provided with dog screw, tightens screw, set lever one, prolongs aluminum pipe and is provided with locating hole, prolongs adapter sleeve and is sleeved on and prolongs on the aluminum pipe, and dog screw inserts in the locating hole.

Described interstage sleeve is between square spigot and oiliness bearing.

Described prolongation adapter sleeve is provided with opening tightening the screw link.

The beneficial effects of the utility model are: the extension rod combination of adopting this technical scheme to make, increased the pruning job area of graden machine, use and easy to carry has reduced the use of other aids, significantly improve operator's operating efficiency, improved security.

Sequence number explanation in the accompanying drawing: 1, Hose Jacket; 2, square spigot; 3, prolong hard axle; 4, interstage sleeve; 5, support set; 6, oiliness bearing; 7, prolong aluminum pipe; 8, dog screw; 9, couple-extended shaft; 10, square hole in the couple-extended shaft; 11, prolong adapter sleeve; 12, set lever one; 13, connecting axle; 14, square hole in the connecting axle; 15, adapter sleeve; 16, set lever two; 17, tighten screw; 18, thread head; 19, screwed hole; 20, locating hole; 21, hard axle square spigot; 22, aluminum pipe; 23, opening.

The specific embodiment

Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, Hose Jacket 1, prolong hard axle 3 (square spigot 2, thread head 18), interstage sleeve 4, prolong that hard axle supports (support set 5, oiliness bearing 6), prolongs aluminum pipe 7 (locating hole 20), prolongs adapter sleeve 11 (dog screw 8, tighten screw 17, set lever 1, opening 23), couple-extended shaft 9 (square hole 10 in screwed hole 19, the couple-extended shaft) forms.

Oiliness bearing 6 is contained in the support set 5, and is sleeved on the hard axle 3 of prolongation, and interstage sleeve 4 is enclosed between the square spigot 2 and oiliness bearing 6 that prolongs hard axle 3, and the thread head 18 that prolongs hard axle 3 screws in the screwed hole 19 of couple-extended shafts 9, and support set 5 is packed into and prolonged in the aluminum pipe 7.

Dog screw 8 and tighten screw 17 and be positioned at an end that prolongs adapter sleeve 11, set lever 1 is positioned at the other end, prolonging adapter sleeve 11 is enclosed within on the prolongation aluminum pipe 7, dog screw 8 inserts in the locating hole 20, tighten screw 17 and pass opening 23 and will prolong adapter sleeve 11 and be fastened on and prolong on the aluminum pipe 7, Hose Jacket 1 is enclosed within the other end that prolongs aluminum pipe 7.

Specific works process of the present utility model: extension rod is made up A be connected with B section, the C section of segmented facility, take off pipe box 1, cooperate with it in the square hole 14 in the connecting axle of square spigot 2 insertion connecting axles 13, the set lever two 16 of cover on 15 is rotatably connected, make it to hold out against long aluminum pipe 7, namely finish the connection that A is connected with B; In square hole 10 in the hard axle square spigot 21 insertion couple-extended shafts, rotational lock handle 1 makes it to hold out against aluminum pipe 22, namely finishes the connection that A is connected with C, A, B, the assembling of C three parts are finished, and have reached the effect of the utility model increase segmented facility entire length.Can assemble organizing extension rod according to the actual job needs more.

Because single group or many groups of extension rod combination are used, increased flexibly the entire length of facility, increased the pruning job area of minute segmentation graden machines such as averruncator, Gao Zhiju, be connected firmly, reliably, accurate positioning, dismounting is simple and easy, packs easy to carryly, has greatly improved operating efficiency and security.
