Abstract
The utility model relates to rechargeable electric shears, belonging to the technical field of an electric tool. An electric source is arranged in the rear part of a shell body, and an output shaft of the electric source is fixedly connected with a driving spiral bevel gear in a coaxial manner; a bracket is fixed at the front part of the shell body; a driven spiral bevel gear which is meshed with the driving spiral bevel gear is supported at the rear part of the bracket, and the driven spiral bevel gear is fixedly connected with a middle gear in a coaxial manner; a lower shear blade is fixed at the front part of the bracket, and an upper shear blade which is jointed with the lower shear blade is supported at the front part of the bracket by a hinge; the lower shear blade is fixedly connected with a segment gear, and the segment gear is meshed with the middle gear; and a second-class gear speed-reducing transmission mechanism is composed by the driving spiral bevel gear, the driven spiral bevel gear, the middle gear and the segment gear. When in working, the electric source drives the upper shear blade to rotate winding a hinge-supporting center by the transmission of the second-class gear speed-reducing mechanism, so as to finish the shearing action with the lower shear blade; therefore, strong torque can be output, thus smoothly finishing the shearing operation with large resistance, such as shearing branches and the like.
Description
Technical field
The utility model relates to a kind of electronic cutting implement, and especially a kind of rechargeable electric clippers belongs to the electric tool technical field.
Background technology
Understand according to the applicant, electronic cutting implement such as original electric clippers generally adopts the reciprocating mechanism of crank block and so on to carry out transmission of power, and its output torque is limited, when carrying out operation such as branch pruning, often is short of power, and is difficult to finish required operation.
The utility model content
The purpose of this utility model is: the deficiency at above-mentioned prior art exists proposes the powerful rechargeable electric clippers of a kind of output torque, thereby satisfies the bigger shearing manipulation needs of resistance such as branch.
In order to reach above purpose, settle electronic source in the housing rear portion of rechargeable electric clippers of the present utility model, the output shaft in described electronic source is connected with spiral bevel driving gear is coaxial; The front portion of described housing is fixed with support; The bevel driven of the back support of described support and spiral bevel driving gear engagement, described bevel driven is connected with idler gear is coaxial; Described support front portion is fixed with bottom knife, and hingedly has and the involutory cutter of described bottom knife; Described bottom knife and sector gear are connected, described sector gear and idler gear engagement; Described active and bevel driven and idler gear and sector gear formation secondary gear reduction gearing mechanism.
During work, electronic source drives cutter and rotatablely moves around hinged center by the transmission of second gear reduction unit structure, finishes shear action with bottom knife, therefore can export powerful moment of torsion, finishes the bigger shearing manipulations of resistance such as branch smoothly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the blast structural representation of an embodiment of the utility model.
Fig. 2 is the opening schematic diagram of Fig. 1 embodiment.
Fig. 3 is the closure state schematic diagram of Fig. 1 embodiment.
The specific embodiment
Embodiment one
The rechargeable electric clippers of present embodiment is settled the electronic source of motor 1 and planetary reducer 13 formations, the output shaft in this electronic source and spiral bevel driving gear 3 coaxial being connected as shown in Figure 1 in the housing rear portion.The front portion of housing is fixed with support 6, and the rear portion of this support is shaped on and the vertical central through hole of electronic source output shaft, supports the bevel driven 4 that meshes with spiral bevel driving gear 3 in this through hole, this bevel driven and idler gear 5 coaxial being connected.The front portion of support 6 is fixed with bottom knife 7, and by hinge 10 is hinged the cutter 8 involutory with bottom knife 7 is arranged.The rear end of bottom knife 7 and sector gear 8 are connected, this sector gear and idler gear 5 engagements.Initiatively the diameter of helical gear 3 is less than bevel driven 4, and therefore the diameter of idler gear 5 constitutes the secondary gear reduction gearing mechanism less than sector gear 8.
During use, this electric clippers relies on the energy of the electric energy of rechargeable battery pack as direct current generator, by direct current generator electric energy is converted into kinetic energy, and the output back descends speed by the planetary reducer that is connected on the motor, and output torque is increased.Afterwards, drive bevel driven through spiral bevel driving gear, idler gear is rotated, the sector gear rotation downwards thereupon with the idler gear engagement drives cutter and opens.
Because initiatively spiral umbrella gear 3 middle parts are fixed with small magnet, be fixed with the extreme position Hall element on the wiring board 11 that support 6 one sides are connected, therefore after opening, cutter can produce hall signal, by control circuit motor will be stopped operating, cutter keeps dehiscing maximum, gets ready for shearing branch.(referring to Fig. 2)
When pressing upper and lower switch 2 and 12 simultaneously, the sector gear rotation that makes progress is ordered about in the motor reverse rotation, drives cutter and makes edge of a knife closure, shears branch, until being installed in the Hall element (referring to Fig. 3) that small magnet on the spiral bevel driving gear runs into opposite side.Control circuit is controlled motor once more and is stopped operating.After unclamping upper and lower switch, the motor forward rotation, cutter opens again, gets ready for shear branch next time.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
