Embodiment

Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.

The utility model electric shrub and hedge trimmer is mainly used in the pruning of tree branch.To shown in Figure 7, the utility model electric shrub and hedge trimmer comprises battery pack 1 as Fig. 2, the jockey group 2 of battery pack and motor, left side casing 3, discharge cock push button spring 4, discharge cock push button 5, discharge cock 6, hexagon socket head cap screw 7, ledger-plate 8, knife section 9, lock(ing) bolt 10, microswitch 11, helical gear set bolt 12, spiral canine tooth wheels 13, helical pinion 14, switch 15, switch spring 16, shift knob 17, motor 18, motor fixing plate 19, change gear box 20, gear-box baffle plate 21, the left front shell 22 of power, helical gear baffle plate 23, helical gear baffle plate screw 24, main shaft 25, needle bearing 26, roller cup 27, deep groove ball bearing 28, gear-box baffle plate screw 29, bearing 30, motor fixing plate screw 31, the right front shell 32 of power, right casing 33, spacer screw 34, spacer 35 and lock nut 36.

Battery pack 1 provides kinetic energy, the jockey group 2 of battery pack and motor guarantees that battery pack and motor are communicated with, the jockey group 2 of battery pack 1, battery pack and motor is positioned at a side of left casing 3, and discharge cock push button spring 4, discharge cock push button 5 and discharge cock 6 are formed a combination and guaranteed that switch resets and is communicated with; Hexagon socket head cap screw 7, ledger-plate 8, knife section 9, lock(ing) bolt 10 and microswitch 11 are formed a blade unit, and ledger-plate 8 is fixed on the left casing 3 by hexagon socket head cap screw 7, and microswitch 11 makes knife section 9 that position-limiting action is provided; Motor 18, change gear box 20, helical gear set bolt 12, spiral canine tooth wheels 13, helical pinion 14, main shaft 25, needle bearing 26, roller cup 27, deep groove ball bearing 28, gear-box baffle plate screw 29 and bearing 30 are formed transmission mechanism, bearing 30 fixed main shafts 25, and guarantee main shaft 25 smooth rotations; Switch 15, switch spring 16 and shift knob 17 form switch combination, and switch spring 16 is given 15 reset responses of switch.Motor 18 is fixed on the motor fixing plate 19, gear-box baffle plate 21 is between change gear box 20 and the left front shell 22 of power, helical gear baffle plate 23 is fixed on the right front shell 32 of power by helical gear baffle plate screw 24, and spacer 35 is between spacer screw 34 and lock nut 36.
