Abstract
The utility model relates to an electric double-hole pencil sharpener for sharpening leads, which comprises a casing body, a rolling sharpening device which is arranged on the casing body and is used for sharpening the wooden part of a pencil, and a lead sharpening device is composed of a battery, a miniature motor, a lead sharpening wheel and a switch all arranged in the casing body. The utility model has the essential technical scheme that one end of the miniature motor in the lead sharpening device is movably connected with a directional hinge seat in the casing body, and the other end is used for forming a floating sharpening device through a spring support fixed to the casing body. In this way, stable sharpening operation is realized, sharpening force is fundamentally constant, and the sharpening taper and the sharpening quantity of leads can be freely controlled.
Description
The utility model belongs to a kind of pencil sharpener that cuts pencil, particularly a kind of electronic core grinding diplopore pencil sharpener.
Chinese patent communique the 10th volume discloses a kind of " electronic core grinding pencil sharpener " No. 8, the patent No. is 2L93203511.6, is provided with battery, micro machine, switch in the housing of this electronic core grinding pencil sharpener and is fixed on the grinding attachment that the knife shaped tooth metal wheel is formed that has on the micro machine output shaft; Be fixed with the volume turning device of forming by chip area, blade, conical bore on the housing.The lead for retractable pencil that rolls out on the winding apparatus is just in time corresponding with the knife shaped tooth metal wheel.Since the structural limitations of this device, easily broken core during the grinding lead for retractable pencil, and the pen core tapering can not arbitrarily be controlled.
The disclosed another kind of above-mentioned communique " manually diplopore multitool sword pencil sharpener ", its shell are provided with a volume turning device and one and cut core apparatus, and the stream oriented device branch is arranged, and its weak point is that the cutting tapering of lead for retractable pencil can not arbitrarily be controlled.
It is steady that the purpose of this utility model provides a kind of grinding lead for retractable pencil, can control the electronic core grinding diplopore pencil sharpener of lead for retractable pencil tapering.
Above-mentioned electronic core grinding diplopore pencil sharpener, it comprises the volume turning device of the wooden part of pencil of pruning that is provided with on a housing, the housing, the core grinding device of forming by battery, micro machine and switch that is provided with in the housing, wherein: the directed hinge seat of fixing in an end of micro machine and the housing in the core grinding device flexibly connects, the other end is supported by the elasticity thing that is fixed on the housing, and core grinding wheel fixedly connected on the output shaft of micro machine is corresponding with the core grinding pilot hole.
The utility model has the advantages that owing on pencil sharpener, will roll up turning device and core grinding device branch is arranged, and the directed hinge seat in an end of the micro machine in the core grinding device and the housing flexibly connects, the spring of the other end through being fixed on the housing supports the unsteady grinding of composition, so just realized that grinding is steady, the cutting force substantially constant, and can control tapering after the lead for retractable pencil grinding.
Following accompanying drawing has been described an example of the present utility model
Fig. 1 is a structure scheme of erection of the present utility model
Among the figure: housing 1 is the injection moulding piece of a rectangular hollow, is processed with a volume turning device 2 of being made up of chip area, blade, conical bore in one end, only the prune wooden part of pencil and expose lead for retractable pencil of this device 2.In housing 1, be set with a directed hinge seat 1, and be connected with micro machine 3 through connecting pin, supported by the spring 5 that is fixed on the housing 1 along the motor 3 axial other ends, at the fixedly connected tapered core grinding wheel 6 of the output axle head of micro machine 3, core grinding wheel 6 is corresponding with core grinding pilot hole 7, battery and switch are arranged in the housing 1, when opening switch, power turn-on, micro machine 3 rotations, with pencil 7 insertions from the core grinding hole that volume is cut, lead for retractable pencil just can contact with the core grinding wheel 6 that rotates and realize grinding.Because motor 3 is that the guaranteed lead for retractable pencil that floats contacts with the good flexibility of core grinding wheel 6, realize that grinding is steady.The control of the tapering of lead for retractable pencil then is that housing is provided with one and adjusts screw 8, and this screw 8 can directly withstand on the micro machine 3 and be corresponding with spring 5.But adjust the grinding angle and the stock removal of the lead for retractable pencil in screw 8 cone governor shape core grinding wheels 6 and the core grinding pilot hole 7.
Claims (2)
1, a kind of electronic core grinding diplopore pencil sharpener, the volume turning device (2) that comprises the wooden part of pencil of pruning that a housing (1), housing (1) upward are provided with, directed hinge seat (4) flexible connection of fixing in the core grinding device of forming by battery, micro machine (3) and switch that is provided with in the housing (1), an end that it is characterized in that the micro machine (3) in the core grinding device and housing (1); The other end is supported by the elasticity thing (5) that is fixed on the housing (1), and core grinding wheel (6) fixedly connected on micro machine (3) output shaft adapts to hole (7) with core grinding.
