Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Shown in Fig. 1, Figure 1A, Figure 1B, Fig. 1 C, electric hedge shears with rearmounted speed changing structure, comprise electric hedge shears with rearmounted speed changing structure, comprise that the front end of cabinet inner chamber is fitted with tooth base plate 1, tooth maneuvering board 2 and the guide positioning plate 3 of the action that cooperatively interacts by bottom 8 and the loam cake 27 equipped cabinets that form and have inner chamber; Cabinet outside portion installation kit contains the motor assembly of micromachine 19 and controller 26; Motor axis 25 extensions are shaped on the inner chamber that helical gear stretches into the cabinet rear end, and are meshed with the helical gear 22 of cabinet inner chamber; Helical gear 22 is connected with tooth axle 23, and first end of tooth axle 23 is connected with clutch shaft bearing 24 inner rings, and the outer ring of this clutch shaft bearing 24 is fixed on the rear end on micromachine 19 housings; Second end of tooth axle 23 is connected with second bearing, 20 inner rings, and the outer ring of this second bearing 20 is fixed on loam cake 27 outer chambers; Second end of tooth axle 23 passes loam cake 27, and is connected with rotating disk 16, and the card eccentric distance D place of rotating disk 16 is fixed with and is used to control the connecting rod follower that tooth maneuvering board 2 carries out the front and back linear reciprocating motion; The card eccentric distance D of rotating disk 16 is 5mm to 30mm, and 26 of controllers are fixed on the front end on micromachine 19 housings.

The connecting rod follower includes first positioning guide column 14 at the card eccentric distance D place that is installed in rotating disk 16, the peripheral shaft of first positioning guide column 14 is connected to the inner ring of the 3rd bearing 12, the 3rd bearing 12 outer rings then are mounted in the connecting rod 21 back stomidiums, the outer ring of embedded intrinsic the 4th bearing 9 of the front aperture of connecting rod 21, the 4th bearing 9 inner rings then are connected with second positioning guide column 10, and tooth maneuvering board 2 rear ends that are fixed on second positioning guide column 10 are then slided in the chute that fits over the setting of cabinet inner chamber fore-and-aft direction; Maximum displacement between tooth base plate 1 fixed teeth that is involutory and the tooth maneuvering board 2 movable teeth is the twice of card eccentric distance D.

For ease of post-job cleaning, the baffle plate 5 of collecting junk is installed on the guide positioning plate 3, baffle plate 5 has vertical plane and the horizontal plane that is front wide and rear narrow shape.During use, this baffle plate is front wide and rear narrow shape can the more junk of splendid attire.

In order to obtain power resources, controller 26 has the outlet that connects accumulator jar, when the accumulator jar electric weight is not enough, carries out electric energy supplement by charger.

The back Handle of sack or bag 18 of cabinet rear end also is provided with the press button that is used to control controller 26; This press button is divided into three speed thresholds.Use for convenience, preceding Handle of sack or bag 6 is installed on the guide positioning plate 3 by handle location working of plastics crosswise fixed, 18 of back Handle of sack or bag are fixedly mounted under the micromachine of trimmer rear end and cover, and form certain sag with preceding Handle of sack or bag 6, and operation is convenient to be used so that mention.

Have only the movable tooth of tooth maneuvering board 2 to move back and forth during pruning; Guide positioning plate 3, tooth maneuvering board 2 and tooth base plate 1 connect by three gathering sills and three guide screw in the same way; Be fixed with first positioning guide column 14 on the outside card in the footpath of rotating disk 16, the size of its eccentric throw has determined the size of space width and the diameter of manipulating object.

Airtight for the safe and reliable motion that makes, by securing members such as screw screws micromachine 19 housings, cabinet are formed sealed hollow, with micromachine 19 output shafts and the rotating disk 16 of arrangement rotation, and flexible connecting rod 21.

The operation principle and the course of work:

Operation principle with electric hedge shears operation of rearmounted speed changing structure is: finish the shearing operation by the tooth maneuvering board 2 that has as the blade with fixed teeth base plate 1 acting in conjunction that has as the blade during pruning.The concrete course of work is: when the arbitrary gear in start-up control device 26 press buttones three gears, powered to controller 26 by outlet by accumulator jar, so micromachine 19 starts, drive the motor axis 25 that is installed in the output of micromachine 19 power simultaneously; Motor axis 25 extensions are shaped on the inner chamber that helical gear stretches into the cabinet rear end, and are meshed with the helical gear 22 of cabinet inner chamber; Because helical gear 22 diameters are far longer than the helical gear diameter of motor axis extension, therefore, change high rotating speed into the slow-speed of revolution,

The tooth axle 23 of helical gear 22 is coupling and drives rotating disk 16 rotations, then drivening rod 21 and the 4th bearing 9, second positioning guide column 10 at first form reciprocating motion again by first positioning guide column 14, the 3rd bearing 12, and further drive is positioned at tooth maneuvering board 2 rear ends and carries out linear reciprocating motion, because this chute is formed one with fixing cabinet, tooth base plate 1, guide positioning plate 3 and baffle plate 5, so the shearing operation has been finished in

tooth maneuvering board

2 and 1 acting in conjunction of tooth base plate; When the X button switch, accumulator jar stops power supply to controller 26, and micromachine 19 stalls after the dead electricity stop so shearing operation.

When making operation at specific plant for pruning, when manufacturing and designing according to the diameter of plant for pruning, get bigger numerical value and determine the distance of two between cog that movable tooth and fixed teeth are adjacent, but be subjected to the restriction of first positioning guide column, 14 eccentric throws on the rotating disk 16 simultaneously, so the size of eccentric throw the size of space width and the diameter of manipulating object have been determined; Shear operation with the fixed teeth acting in conjunction as having blade and cooperate appropriately for making front end have movable tooth as the blade, on guide positioning plate 3, be distributed with three gathering sills in the same way.

Most preferred embodiment of the present utility model is illustrated, and various variations or the remodeling made by those of ordinary skills can not break away from scope of the present utility model.
