Abstract
The utility model relates to an anti-reversing mechanism in a pencil sharpening device which comprises a winding shaft, wherein the winding shaft is arranged in an outer shell of the pencil sharpening device, one end of the winding shaft is provided with a transmission wheel, at least one spring is arranged outside the transmission wheel, a rotating wheel is arranged outside the transmission wheel, the rotating wheel and the transmission wheel are homocentric, a plurality of teeth are arranged along the circumferential direction on an inner ring of the rotating shaft, tooth edges are arranged unidirectionally, the outer surface of each tooth is composed of an arc surface and a panel, and the outer end portion of a spring is arranged in tooth grooves which are adjacent to the teeth. The anti-reversing mechanism in the pencil sharpening device enables the rotating wheel to rotate forward to drive a pencil sharpener to rotate and the pencil sharpener keeps still when the rotating wheel reverses. The anti-reversing mechanism in the pencil sharpening device solves the problems of low efficiency caused by structure constraint and rattling in the process of reverse and enables a boring sharpening process to be interesting.
Description
Technical field
The utility model relates to the penknife technical field, refers to especially the anti-reverse mechanism in a kind of penknife.
Background technology
Traditional penknife has hob type penknife and pencil sharpener formula penknife, these two kinds of penknifes are when cutting, all adopt and shake swing arm, so that the rotation of swing arm drives spool and is arranged on hobboing cutter or pencil sharpener on the spool, thereby reach the purpose that cuts, this mode that cuts can only one-directional rotation cut, and it is lower to cut efficient, and process is uninteresting.Penknife is because structural limitations, and swivelling cover can not the turn over rotation usually, so have unavoidably reverse rotation, rotates so that cut the position, waits to cut the position and gets back to the blade cutting edge place and just can cut, and this process can cause and cut Efficiency Decreasing.
The utility model content
Technical problem to be solved in the utility model is: a kind of anti-reverse mechanism that can improve in the penknife that cuts efficient is provided.
For addressing the above problem, the technical solution adopted in the utility model is: the anti-reverse mechanism in the penknife, comprise the spool that is arranged in the penknife shell, spool one end is provided with drive, and the drive outside is provided with an elastic arm at least, and the drive outer setting has the moving runner mutually concentric with drive, the moving runner inner ring is along being arranged circumferentially several teeth, tooth is along unidirectional array, and the outer surface of each tooth is made of an arc surface and a plane, and the elastic arm outer end is arranged in the teeth groove of adjacent teeth.
The drive arranged outside has two elastic arms, and two elastic arms are about the drive Central Symmetry.
The beneficial effects of the utility model are: the anti-reverse mechanism in the above-mentioned penknife is so that drive pencil sharpener during the moving runner forward rotation and rotate, keep pencil sharpener motionless during backward rotation, solved the Efficiency Decreasing that causes because of structural limitations, " clatter clatter " sound during counter-rotating is also so that the uninteresting process that cuts has recreational.
Description of drawings
Fig. 1 is the anti-reverse mechanism schematic diagram in the penknife.
Among the figure: 1, spool, 2, drive, 3, elastic arm, 4, moving runner.
The specific embodiment
Below by specific embodiment the anti-reverse mechanism in the utility model penknife is described in further detail.
As shown in Figure 1, anti-reverse mechanism in the penknife, comprise the spool 1 that is arranged in the penknife shell, spool 1 one ends are provided with drive 2, and drive 2 arranged outside have two about drive 2 centrosymmetric elastic arms 3, and drive 2 outer setting have the moving runner 4 mutually concentric with drive 2, moving runner 4 inner rings are along being arranged circumferentially several teeth, tooth is along unidirectional array, and the outer surface of each tooth is made of an arc surface and a plane, and elastic arm 3 outer ends are arranged in the teeth groove of adjacent teeth.
When moving runner 4 forward, drive drive 2 forwards, when moving runner 4 counter-rotating, elastic arm 3 is compressed, drive 2 can not and then rotate, skipping a unidirectional tooth when shell fragment simultaneously just has " clatter " one, just forms continuous " clatter clatter " sound during fast rotational, so that the uninteresting process that cuts has recreational.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (2)
1. the anti-reverse mechanism in the penknife, comprise the spool that is arranged in the penknife shell, it is characterized in that: described spool one end is provided with drive, the drive outside is provided with an elastic arm at least, the drive outer setting has the moving runner mutually concentric with drive, and the moving runner inner ring is along being arranged circumferentially several teeth, and tooth is along unidirectional array, the outer surface of each tooth is made of an arc surface and a plane, and the elastic arm outer end is arranged in the teeth groove of adjacent teeth.
2. the anti-reverse mechanism in the penknife according to claim 1, it is characterized in that: described drive arranged outside has two elastic arms, and two elastic arms are about the drive Central Symmetry.
