Description

Pruner long handle circuit switching construction

Technical field

The utility model relates to a kind of structure of graden machine, specifically is the circuit switching construction after the pruner lengthening connects long handle.

Background technology

Pruner is mainly used in branch or the blade of shearing trees, shrub, to reach the purpose of finishing trees and shrub shape; Pruner needs the two hand-held sets of operating personnel to operate, and is the quite high graden machine of a kind of frequency of utilization.The structure of common pruner is as shown in Figure 1 and Figure 2: annular handgrip 2 is installed on the main frame body 1, the front end of main frame body 1 is equipped with two movable tooth rows 3, electrical power in the main frame body rotates, drive two movable tooth rows and carry out linear reciprocating motion, just produce the required shearing motion of people between some serrated knives on these two movable tooth row dual-side edges.

Fig. 1, pruner shown in Figure 2 are fit to prune closely, tree-like less trees and shrub branches and leaves; In order to prune operation to higher position and at a distance trees and shrub branches and leaves, the inventor on pruner adjunction a long handle; Yet, behind the pruner lengthening, how to operate control easily and effectively, still be the problem that technology to be solved is arranged.

The utility model content

Technical problem to be solved in the utility model provides a kind of circuit switching construction of pruner long handle, this structure should be able to be when original pruner connects long handle commutation circuit effectively, and have convenient, the simple and practical characteristics of host computer control.

The technical scheme that the utility model provides is: pruner long handle circuit switching construction, comprise the long handle that annular handgrip and annular handgrip are pegged graft and connected, and the rear end of described annular handgrip is shaped on one section sleeve pipe, is shaped on external thread on the outer circumference surface of sleeve pipe again; The intubate on long handle top then with the casing inner diameter fit, then locate a rotating turncap on the outer circumference surface of intubate again, the internal thread of this turncap and described external thread fit are so that turncap is tightened on the intubate; Be provided with by-pass switch and collision block in the described sleeve pipe, act on by-pass switch when connecting so that peg graft on annular handgrip and long handle top.

Be equipped with in the intubate on described long handle top and extend to the outer chock of pipe, this chock is pegged graft on annular handgrip and long handle top and is acted on collision block when connecting, and makes the by-pass switch startup.

Also be provided with the supply socket that matches with the pruner attaching plug on the outer circumference surface on described long handle top, the tail end of long handle is provided with power switch again, other has the cable that passes through whole long handle handle bar inner chamber to connect described supply socket and power switch respectively, and power switch also connects the plug that can join with extraneous power supply.

The button of described power switch is installed in the handle inboard of the defensive position handle of long handle tail end.

The supply socket on described long handle top is provided with cover plate.

Use of the present utility model is very simple: the operator only needs the vertical long handle of placing, cooperate aiming at the mouth of pipe on long handle top in the adapter of the annular handgrip rear end of pruner down and the two being inserted, screw turncap then, can make the collision block on intubate top promote the by-pass switch action, make host switch be connect, finish circuit and switch by the side; Again the original attaching plug 24 of pruner is inserted the supply socket 23 on long handle tops then, plug 26 energized of long handle tail end, so just directly main control system operation on the defensive position handle.

The beneficial effect that the utility model produces is: owing to be provided with simple and effective circuit switching construction, operating personnel can the defensive position of the pruner long handle behind the lengthening on directly main control system operation, make more convenient to operate effectively, the scope of work of pruner also is able to remarkable expansion; And labor intensity of operating personnel is alleviated, and work efficiency also is improved, and job safety is more guaranteed.

Embodiment

As shown in the figure, pruner long handle draw bail comprises the long handle 6 that annular handgrip 2 and annular handgrip are pegged graft and connected, and the rear end of described annular handgrip is shaped on one section sleeve pipe 2-1, is shaped on the external thread that connects usefulness on the outer circumference surface of sleeve pipe again; The intubate 6-1 on long handle top realizes connecting with sleeve pipe by inserting fixing structure; Locate a rotating turncap 7 on the outer circumference surface of intubate again, the internal thread of this turncap and described external thread fit make both close-coupled so that turncap is tightened on the intubate.

The rear end of described turncap 7 is shaped on the convex 7-1 that a circle bends towards the external diameter direction; Fix one on the outer circumference surface of intubate and keep the collar 8 of a determining deviation with intubate surface, the collar top forms a circle edge 8-1 who bends towards the intubate surface, and this edge cooperates with the convex embedding of described turncap, makes turncap keep rotating positioning states.

Also being provided with by-pass switch in the described sleeve pipe is BYPASS) 21 and collision block 20, act on by-pass switch (as shown in Figure 8: the plastics chock 5 that extends to outside managing is housed in the intubate on described long handle top so that peg graft when connecting on annular handgrip and long handle top, this plastics chock is pegged graft on annular handgrip and long handle top and is acted on collision block when connecting, makes the by-pass switch startup).Also be provided with the supply socket 23 that matches with the pruner attaching plug on the outer circumference surface on described long handle top, the tail end of long handle is provided with power switch (specifically being installed in defensive position in 28 inner chambers) again, other has the cable (omitting among the figure) that passes through whole long handle handle bar inner chamber to connect described supply socket and power switch respectively, and power switch also connects the plug 26 that can join with extraneous power supply.

The button 22 of described power switch (semicircle button) is installed in the handle inboard of the defensive position handle of long handle tail end; More help easy to operate.

The supply socket on described long handle top is provided with cover plate 23-1, and other is subjected to a spring pressure, so that cover socket when the supply socket non-working condition, keeps the clean and tidy and safety at electric power connecting position.
