Embodiment:

With reference to Fig. 1, Fig. 2 and Fig. 3, backpack tea bush trimmer machine, include the power assembly of forming by miniature gasoline engine 11 1, this power assembly 1 also comprises corresponding gear, power assembly 1 is packed on the support assembly 2, the rotation output of power assembly 1 passes to blade assembly 3 through flexible axle 12, drives upper and lower blade dislocation motion.

With reference to Fig. 2, blade assembly 3 comprise be positioned on the rigidity guide card 31 on, bottom knife 32,33, rigidity guide card 31 1 ends are fixed on the cutter head housing 30, on, bottom knife 32, an end of 33 is in transmission connection with the double-track cam 350 of a gear wheel 35 mutually by hinge plate 34 respectively, pinion 360 engagements of gear wheel 35 and a commutation bevel gear 36 disjunctors, cutter head housing 30 Kinematic Positioning have a bar head 4, be fixed with an action bars 41 on the bar head 4, action bars 41 is built-in with a guide shaft 42, guide shaft 42 1 ends dock with flexible axle 12, the other end through bevel gear 43 and be installed in bar head 4 and cutter head housing 30 between the engagement of one of double end bevel gear 37 head, double end bevel gear 37 other ends and 36 engagements of commutation bevel gear.

Commutation bevel gear

36 and 30 of cutter head housings,

bevel gear

43 and 4 on bar head are respectively equipped with the bearing 6 of location.

Upper and lower blade 32,33 on rigidity guide card 31, can be regulated the gap of two blades by bolt 5 Kinematic Positioning by bolt 5.

With reference to Fig. 2 and Fig. 3, described cutter head housing 30 cooperates with the circular interface of bar head 4 linking parts, and also by a bearing pin 44 location, bearing pin 44 passes double end bevel gear 37 to intussusception mutually, and 44 of double end bevel gear 37 and bearing pins are pivoted with sliding shaft sleeve 38.Circular interface cooperates can make both under the situation that does not change inner drive connection, realizes the adjusting of both relative angles.For this reason, be provided with an angle locking mechanism at cutter head housing 30 and bar head 4 linking parts, this angle locking mechanism comprises that one is fixed on the toothed disc 7 of bar head 4 one sides and is positioned at cutter head housing 30 1

side lock hooks

71,30 of lock hook 71 and cutter head housings are pivoted with a torsion spring 72, and torsion spring 72 remains on the teeth that lock hook 71 is buckled in toothed disc 7.Be touched easily for fear of lock hook 71, lock hook 71 also is equipped with a safety fastener 73, safety fastener 73 be positioned on the cutter head housing 30 and with lock hook 71 shared torsion springs 72, torsion spring 72 can remain safety fastener 73 again and pin lock hooks 71 trend.When the need adjusting angle, open safety fastener 73 in advance, remove locking to lock hook 71, after this lock hook 71 could move, releasing is to the restriction of toothed disc 7 teeth, make bar head 4 relatively cutter head housing 30 do relative rotation adjustment angle.For the ease of the operation of angular adjustment, be fixed with one handle 39 at cutter head housing 30 rear portions, make handle 39 and action bars 41 become class shear shank relation.This handle 39 is except the need of adjusting angle operation, and it also can be used as the main lever of blade assembly 3 when cooperating short operation bar 41 to prune among a small circle, and perhaps both hands are held in respectively on handle 39 and the action bars 41, prune operation.

Action bars 41 can also can be stock or be telescopic stock as the quarter butt among the figure, and realization length can be regulated, and satisfies the pruning of different occasions, differing heights branches and leaves.For this reason, on the spacing that action bars 41 is fit to hold, be arranged with forward and backward handgrip gum cover 411,412 respectively, so that control more sane, also can alleviate the fatigue of both hands, moreover the Throttle Opening Control switch 110 of gasoline engine can be fixed on defensive position by the gum cover, convenient finger is stirred control, as Fig. 1.
