Double-blade multifunctional pencil sharpener convenient to disassemble
Technical Field
The utility model belongs to the technical field of the stationery technique and specifically relates to a multi-functional ware of cutting of double knives convenient to dismantle.
Background
The pencil sharpener, also called a pencil sharpener or a pencil sharpener, is a tool for sharpening a pencil, and the pencil sharpener is divided into an electric sharpener and a manual sharpener, wherein the manual sharpener is divided into a hand sharpener and a manual sharpener without hand cranking. Hand pencil sharpener passes through the twist grip, can accomplish and dig a function, can make closed structure usually, and the bits box is the mode of horizontal pull for the pencil piece is difficult for scattering.
There is a need in the art for a dual-blade multifunctional pencil sharpener that is easy to disassemble and replace a pencil sharpening assembly or clean a pencil scrap box.
SUMMERY OF THE UTILITY MODEL
The utility model provides a convenient to detach's multi-functional ware of cutting of double knives of realizing above-mentioned purpose.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a multi-functional ware of cutting of double knives convenient to dismantle, include the shell, set up in two advance a subassembly and a bits box in the shell and set up in the outer handle of shell, the shell include the casing with can dismantle connect in the back lid of casing rear end, the gear train set up in back is covered, the handle passes through the gear train drive accomodate in two in the shell cut a subassembly, it has three knob mounting hole to open on the casing, back is covered the activity and has been worn to put three one end and insert threely the knob in the knob mounting hole, this a little relatively be provided with two draw-in grooves on the knob mounting hole, this a little be equipped with on the knob with corresponding two draw-in groove matched with two archs.
Compared with the prior art, the beneficial effects of the utility model are that:
due to the adoption of the structural design, the protrusions on the knob are matched with the clamping grooves in the knob mounting hole, and the rotary clamping structure is formed, during mounting, the knob is pushed into the knob mounting hole to rotate for a certain angle, so that the protrusions and the clamping grooves can be clamped, the rear cover is fixed with the shell, during dismounting, the knob and the rear cover can be successively taken down by reversely rotating for a certain angle, the mounting and dismounting convenience of the rear cover is greatly improved, and the replacement of the pencil sharpening assembly and the cleaning of the pencil scrap box are facilitated.
