Background

At present, along with the continuous expansion of urban greening areas, green belts of parks, roads and public places are spread all over the country, and because the growth of green plant branches needs to be frequently trimmed for ordered formation, the electric pruning shears are increasingly applied, and the electric pruning shears are widely used as a garden tool due to small and exquisite shapes and convenient carrying. The electric pruning shears comprise a pair of blades extending from a housing, one of the blades being fixedly mounted to the housing and the other blade being pivotally connected to a fixed blade and driven by a motor to oscillate back and forth. When the trigger is pulled, the motor rotates forwards to drive the movable blade to swing towards the fixed blade, so that branches are cut, and the blade edge is closed; when the trigger is loosened, the motor rotates reversely to drive the movable blade to swing towards the direction away from the fixed blade, the knife edge is opened, the scissor head assembly of the existing electric pruning shears is troublesome to mount, the scissor head assembly needs to be arranged on the outer side of the fixing seat, the overall structure of the pruning shears is complex and large, the blade is fixedly mounted on the machine shell, the service life of the pruning shears can be influenced due to pressure impact during pruning for a long time, the overall appearance is not attractive, the internal structure is unreasonable, the existing blade is mounted on the other side of the gear and is not on the same straight line with the center of the grab handle, and the use is inconvenient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an electric pruning shear to overcome the above-mentioned not enough that exists among the prior art.

In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows:

the utility model provides an electric pruning scissors, which comprises a housin, the afterbody inboard of casing is equipped with the motor, the head outside of casing is equipped with the blade lid, the motor links with the battery electricity, the output shaft of motor has the reducing gear box, the output shaft of reducing gear box has the gear train, the gear train is connected with the tool bit subassembly, the tool bit subassembly is including the fixed blade support of locating on the reducing gear box casing, the fixed blade of locating on the blade support and the movable blade of locating on the blade support, the one end an organic whole of blade is provided with the rack, the gear train includes the first bevel gear with reducing gear box output shaft, rotate the second bevel gear of locating blade support one side and the straight-teeth gear with the coaxial setting of second bevel gear, first bevel gear and second bevel gear mesh, straight-teeth gear and rack mesh mutually.

Furthermore, the shell comprises a tail seat cover, a holding cover and a cutter head cover, the motor, the reduction gearbox and the gear set are arranged in the holding cover, and the cutter head assembly is arranged in the cutter head cover.

Furthermore, a transmission switch corresponding to the gear set is arranged on the holding cover and connected with and controls the motor.

Further, the shape of the rack is fan-shaped.

The utility model has the advantages that: the integral structure is simpler, the disassembly and the maintenance of a user are more convenient, the occupied space inside the electric pruning shears can be reduced, the internal structure is more reasonably arranged, the straight gear and the first gear are arranged, the external pruning effect of the cutter head component is ensured by utilizing the matching of the straight gear and the cutter head component, the cutter head component and the straight gear are arranged on one side of the first gear, the integral appearance is more attractive, the stability of the cutter head component during working is better, in addition, the cutter head component and the gear component are arranged on the same side of the blade support and are kept on the same vertical line with the grab handle, and the operation and the use of the user are more convenient; set up the tool bit lid, on the one hand can reduce the blade because of the probability that accident damaged, on the other hand also can avoid because the blade fish tail human condition that accident appears.
