Detailed description of the invention
The utility model is further described by specific embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, described a kind of penknife structure, comprise the penknife housing 1 being provided with and pinching a mechanism 2 and handle 3, pinch a mechanism 2 and be provided with pen-laying hole 21, be provided with in described penknife housing 1 and be interconnected and the planing frame 4 of synchronous axial system with handle 3, handle 3 described in the utility model and planing frame 4 are for being threaded, so that mounting or dismounting are convenient, as Fig. 4, shown in Fig. 5, planing frame 4 is arranged with the adz block 5 of a band blade 51, offer the penholder corresponding with pen-laying hole 21 in adz block 5 to lead taper hole 52, blade 51 on described adz block 5 is arranged on the conical surface of penholder guiding taper hole 52, the blade of described blade 51 is parallel with the conical surface and embed penholder and lead in taper hole 52, as shown in Figure 2, described planing frame 4 is cylindrical structural near one end of pen-laying hole 21 and inside is provided with a ratchet 6, described ratchet 6 is the structure of one end and the fit inside of planing frame 4 cylindrical structural wherein, the other end adopts the mode of matched in clearance to be fixed on the pencil porch of penknife housing 1 inside, the inside of described ratchet 6 offers the corresponding screwed hole 61 of the taper hole 52 that to lead with penholder, the diameter of screwed hole 61 is greater than the diameter of pencil 7 penholder, the described outer ring pinching the pen-laying hole 21 of close planing frame 4 side in a mechanism 2 is provided with several elastic arms 231 stretched out to planing frame 4 direction, the end of described elastic arm 231 external part is mutually gathered and is respectively arranged with external screw thread, and described elastic arm 231 and screw thread form corresponding with the screwed hole 61 of ratchet 6 inside matches.
Described in the utility model pinch that a mechanism 2 comprises that a pencil holding mechanism 22 and one fixes with it draw pen stand 23, described side of drawing pen stand 23 to be arranged on close planing frame 4, as shown in Figure 3, described elastic arm 231 is arranged on and draws on pen stand 23, with convenient elastic arm 231 go wrong need to change time we only need to change separately and draw pen stand 23 just can, and need not the whole mechanism 2 that pinches be changed, save maintenance cost;
The periphery of ratchet 6 other end described in the utility model is provided with several snap fits 62 stretched out, the porch corresponding the inside pencil of penknife housing 1 is provided with the round boss 11 that has through hole, boss 11 offers a circle groove 111, the snap fit 62 of described ratchet 6 is fastened on the interior formation matched in clearance of groove 111 of boss 11, this cooperation fixed form is conducive to the mounting or dismounting of ratchet 6, be convenient to carry out maintaining to it, and snap fit 62 and groove 111 matched in clearance are the rotations in order to not affect ratchet 6.
During use, pencil 7 is inserted pen-laying hole 21 until in penknife housing 1, pinch a mechanism 2 to clamp pencil 7 and pulled open outward, under the spring action pinching a mechanism 2, pencil 7 is along with pinching a mechanism 2 by past lira, hand cranking handle 3 rotates clockwise, drive the adz block 5 equidirectional rotation together on planing frame 4 and planing frame 4, just starting, the decrement of spring is larger, so elastic force is comparatively large so that can will pinch a mechanism 2 toward lira, thus complete leading portion cutting, when being cut to below, amount of spring compression reduces, elastic force reduce thereupon so that do not have enough power again by pencil 7 toward lira, now continue hand cranking handle 3, as shown in Figure 6, because the front end of elastic arm 231 struts by pencil 7 in pen-laying hole 21 already, the screw thread of elastic arm 231 front end is matched with the screw thread of ratchet 6 inside, under the effect of threaded engagement, become guide screw movement, thus the whole mechanism 2 that pinches is continued toward lira, finally complete cutting, after cutting completes, extract pencil 7, now elastic arm 231 front end recovers to gather state and depart from the screw thread of ratchet 6 inside and coordinate, thus pinches a mechanism 2 and just can again be pulled open outward, carries out next round cutting.
The utility model planing tool instead of hobboing cutter traditional, thus reduces the cost of penknife, and it is more easy to change cutter, only new adz block directly need be replaced old planing tool toilet can, energy-conserving and environment-protective, usability is high, can Long-Time Service, and chip is functional.
