Abstract
The utility model belongs to the field of pencil sharpening devices, and particularly relates to a hand-cranking pencil sharpening device with a labor-saving device of an internal meshing gear structure. The hand-cranking pencil sharpening device with the labor-saving device of the internal meshing gear structure saves time and labor, is simple in structure and comprises a main box body, a conveying device, a cutting device and a pencil sharpening box. The conveying device, the cutting device and the pencil sharpening box are all arranged inside the main box body. The cutting device comprises an installation frame, an operating handle, a rotary body, a sharpener and the speed-reduction labor-saving device, wherein the speed-reduction labor-saving device enables the operating handle to save labor and enables force to be transmitted to the rotary body, the speed-reduction labor-saving device is an internal meshing gear, the internal meshing gear comprises an internal gear body and an external gear body, the internal gear body is connected with the rotary body, and the external gear body is connected with the operating handle. The hand-cranking pencil sharpening device with the labor-saving device of the internal meshing gear structure has the advantages that the rotation speed of the operating handle is reduced through the speed-reduction labor-saving device, rotation of the operating handle is transmitted to the rotary body to enable the rotary body provided with the sharpener to rotate with large rotary force, meanwhile, the number of rotation times of the operating handle is decreased, and the structure is also simplified.
Description
Technical field
The utility model belongs to pencil sharpener field, is specifically related to a kind of hand pencil sharpener of work-saving device of inside engaged gear structure.
Background technology
Pencil sharpener comprises organic main body, pencil holding mechanism, pencil sharpener structure and bits box, wherein considers to be worth doing to turn round bear pencil sharpener portion at the bottom of box and be provided with the groove that a pencil sharpener can accommodating penknife, and a penknife plugs and is positioned in groove.User can select the main penknife work in pencil sharpener pencil sharpener structure, or the penknife taking out on bits box utilization bits box is cut pen; If the main penknife of pencil sharpener is flat knife, after its passivation, the penknife in bits box can be taken out, replace main penknife, form the pencil sharpener that an edge of a knife is sharp.The utlity model has reasonable in designly, not destroying on the basis of pencil sharpener structure and bits kit function, set up a penknife, one is convenient to the penknife tool that user changes passivation, extends the life-span of pencil sharpener, reduces discarded object quantity; Two can form and have complementary functions with spiral hobbing cutter, and different demands all can be met.
In patent documentation 1 (6-No. 48094 communiques of Unexamined Patent), shown the Manual pencil sharpener that operation handlebar is housed.The rotating shaft of cutter is housed in this pencil sharpener and the center of operation handlebar is connected, with hand, makes operation handlebar rotation, by the cutter together rotating with rotating shaft, sharpen a pencil.Yet, as the rotating shaft that cutter is housed in patent documentation 1 and the direct pencil sharpener linking of operation handlebar, when sharpening a pencil, need larger strength just can make operation handlebar rotation.Therefore, for the child of strength deficiency particularly, wait, the operation of rotary manipulation handle can become burden.
A kind of pencil sharpener is disclosed patent documentation 2(CN201110270133.X), the rotating shaft that cutter is housed in this pencil sharpener is connected with the center of operation handlebar by the gear by upper and lower three layers, although this pencil sharpener utilizes upper and lower three layers of gear to alleviate the strength that child sharpens a pencil, when sharpening a pencil due to by three layers of gear driven, so the number of revolutions of rotating operation handle can be a lot, more time-consuming and structure is also complicated.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of hand pencil sharpener of work-saving device of a kind of inside engaged gear structure time saving and energy saving and simple in structure is provided.For realizing technique scheme, the utility model is the hand pencil sharpener of the work-saving device of so a kind of inside engaged gear structure realizing, comprise main cartridge, conveyer, topping machanism, the box of pleasing correct, described conveyer, topping machanism and the box of pleasing correct are all located in main cartridge, described topping machanism comprises installing rack, operation handlebar, rotary body and sharpener, described topping machanism also comprises deceleration work-saving device, this deceleration work-saving device makes operation handlebar laborsaving and conduct to rotary body, it is characterized in that, described deceleration work-saving device is inside engaged gear.
Described inside engaged gear is an internal gear and an external gear, and described internal gear is connected with rotary body, and external gear is connected with operation handlebar, and described operation handlebar rotates around the longitudinal axis, and described cutting combination and the box of pleasing correct are arranged on main body box in dismounting mode.
Technique scheme is done further to analyze, described deceleration work-saving device consists of inside engaged gear, described external gear is located in installing rack and is connected with operation handlebar, described internal gear is connected with rotary body, when the clockwise longitudinal axis rotation of operation handlebar, owing to being so that inside engaged gear becomes same direction rotation with operation handlebar direction of rotation, the rotary body being connected with internal gear and sharpener will with internal gear centered by rotate, and, the now internal gear phase interlock on the planet screw portion of sharpener and rotary body, sharpener rotates centered by axle thus.And, when now sharpener revolves round the sun centered by the external thread part of rotary body, autobiography centered by axle, by the blade of sharpener, the head of the pencil inserting in above-mentioned support tube is sharpened.
The utility model has the advantages that: thereby the utility model slows down the rotation of operation handlebar by deceleration work-saving device, conduct to rotary body, the child of strength deficiency etc. the rotary body that sharpener is housed can be rotated with larger revolving force, even also can sharpen a pencil simply.Meanwhile, the number of revolutions that has reduced operation handlebar also simplifies the structure.
