The automatic Song Bi mechanism of penknife of the present utility model, the front-rear side walls of described support 1 is equipped with fixing card convex 17 near bottom end.
The automatic Song Bi mechanism of penknife of the present utility model, the mesopore inwall of described end-tooth pad 8 is provided with spline bar 18, and the outer wall of roller shaft 4 is provided with the keyway 19 matched with spline bar 18.
The automatic Song Bi mechanism of penknife of the present utility model, the left plate of described support 1 is provided with two fixing holes 20 for fixed idler whell axle 4, the right side wall top of support 1 is provided with two jacks 21, the top of jack 21 is equipped with the first semi-circular hole 22, locating dowel 23 is provided with in the middle part of the bottom face of described briquetting 3, the both sides of locating dowel 23 are equipped with the second semi-circular hole 24, the both sides of the second semi-circular hole 24 are equipped with the pin 25 inserting jack 21 inside, the tip-end-side of pin 25 is equipped with positioning table 26, after briquetting 3 and support 1 grafting, the first semi-circular hole 22 and the second semi-circular hole 24 fasten mutually for fixed idler whell axle 4, positioning table 26 mainly plays positioning action when carrying out screw connection.
The automatic Song Bi mechanism of penknife of the present utility model, is fixed by screw 27 after described briquetting 3 is connected with support 1.
The automatic Song Bi mechanism of penknife of the present utility model, described in roll pen wheel 5 outer wall be provided with annular recess, roll pen wheel 5 adopt elastomeric materials make.
The automatic Song Bi mechanism of penknife of the present utility model, the outer wall of described toothed wheel 7 is provided with tooth-like recesses, and toothed wheel 7 adopts elastomeric material to make.
The automatic Song Bi mechanism of penknife of the present utility model, when described rotating disk 2 is rotated counterclockwise, drive the toothed wheel 7 be fixed in wheel case 6 to rotate, the wheel case 6 on two roller shafts 4 is close to rolls pen wheel 5, the effect of frictionally, the pen wheel 5 that rolls be fixed on roller shaft 4 drives lower rotation by wheel case 6, pencil 28 feeding is driven to cut pen, when cutting after pen puts in place, pencil 28 no longer feeding, rubbing surface skids, and is unlikely to force feeding and makes nib broken.When rotating disk 2 turns clockwise, under the effect that wheel case 6 rotates in toothed wheel 7, wheel case 6 on two roller shafts 4 is away from rolling pen wheel 5, the teeth groove 10 of wheel case 6 end face outside engages with the end-tooth 9 of end-tooth pad 8, spline bar 18 by end-tooth pad 8 acts on, wheel case 6 drives roller shaft 4 to rotate, and the pen wheel 5 that rolls be fixed on roller shaft 4 rotarily drives pencil 28 and exits penknife.
The automatic Song Bi mechanism of penknife of the present utility model, the part pyramid like configuration of rotating disk 2 upper surface, when feeding, toothed wheel 7 is more and more nearer with rotating disk 2 conical surface distance, and toothed wheel elastic deformation is increasing, and frictional force is increasing; During feeding, wheel case 6 is near rolling pen wheel 5, and circular cone rotating disk 2 drives the linear velocity of toothed wheel 7 more and more less, and toothed wheel 7 rotating speed is just more and more lower; When to move back, toothed wheel 7 is more and more far away with rotating disk 2 conical surface distance, toothed wheel 7 elastic deformation is more and more less, frictional force is more and more less, active force is more and more just little, but because lean on the effect of end-tooth pad 8, the end-tooth 9 of end-tooth pad 8 engages with the teeth groove 10 of wheel case 6 end face outside, toothed wheel 7 drives roller shaft 4 to rotate, and then pen wheel 5 rotation is rolled in drive, forces pencil to move back pen, more reliable performance; When to move back, wheel case 6 is away from rolling pen wheel 5, and circular cone rotating disk 2 drives the linear velocity of toothed wheel 7 large, and toothed wheel 7 rotating speed is just high, and it is high to move back pen speed degree, thus moves back pen and enter pen speed degree different, easy to operate.
Penknife of the present utility model send a mechanism structure reasonable in design automatically, can with manually, electro-motion pencil sharpener structure with the use of, can be quickly assembled on penknife housing by fixing card convex, turntable rotation is driven by pencil sharpener cutter rest, pencil 28 is driven to retreat finally by rolling pen wheel, the top of rotating disk is the part pyramid like configuration projected upwards, when to enter, penknife structure drives turntable rotation, frictional force due to bar shaped convex tendon makes toothed wheel to rotating disk medial movement, the teeth groove of wheel case departs from the end-tooth (as shown in Figure 8) of end-tooth pad, and toothed wheel reduces gradually to linear velocity during rotating disk medial movement, enter a speed goes slow, toothed wheel rotating speed is lower, when nib encounters gear pen position, toothed wheel and rubber roll pen and take turns end face and skid, thus be unlikely to make nib broken, inner side fluted disc is high, and frictional force is just large.When to move back, penknife structure drives rotating disk reversion, bar shaped convex tendon frictional force makes toothed wheel move outside rotating disk, the teeth groove of wheel case is engaged (as shown in Figure 9) mutually with the end-tooth of end-tooth pad, and toothed wheel when moving outside rotating disk linear velocity increasing, move back a speed goes fast, toothed wheel rotating speed is just more and more higher, outside fluted disc is low, frictional force is just little, move back pen laborsaving also quick, reliable in order to make to move back pen, be provided with the end-tooth pad be connected with the keyway of roller shaft, the keyway of roller shaft forces roller shaft to rotate under the effect of spline bar, thus make into time roller cover with roll the frictional force feeding that pen takes turns, when to move back, toothed wheel forces roller shaft to rotate, this institution staff is reliable, easy to operate, Quick labor-saving, noise is little, after briquetting and support grafting, the first semi-circular hole and the second semi-circular hole mutually fasten and become a complete circle post holes for fixed idler whell axle in addition, and positioning precision is high, dimensionally stable is reliable, assembling is quick, the bottom of support arranges the card convex of two fixing automatic Song Bi mechanisms, and easy to assembly quick reliable, efficiency of assembling improves obviously.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
