Abstract

The invention relates to a pencil sharpener transmission structure which comprises a hob head connected with a pencil sharpener handle and rotates with the same synchronously. A hob and a hob gear arranged on the hob head. A driving gear is fixedly connected to the outer ring of a transmission end of the hob head. A hob driving gear capable of rotating freely and a transmission gear are also arranged on the outer ring of the transmission end of the hob head, and are connected with each other fixedly and capable of rotating synchronously. The transmission gear and the driving gear correspond to each other in position, and the diameter of the transmission gear is larger than that of the driving gear. At least one idler is fixedly arranged between the transmission gear and the driving gear, and respectively matched with internal teeth of the transmission gear and external teeth of the driving gear. Internal teeth of the hob driving gear mesh with external teeth of the hob gear. Relative rotation between the hob driving gear and the hob gear accelerates rotation of the hob, thereby improving sharpening efficiency of pencil sharpeners.

Description

A kind of drive mechanism of penknife
Technical field
The present invention relates to a kind of drive mechanism of penknife.
Background technology
As shown in Figure 1, hob head 1 is fixed on housing 2 prior art by hobboing cutter fixed mount and left support, and handle 3 is connected with hob head 1, drives hob head 1 to rotate around its center when handle 3 rotates; Hobboing cutter 5 is fixed on hob head 1 again by hobboing cutter steady pin 4, hobboing cutter 5 can be rotated around hobboing cutter 5 Pivot Point Center on hobboing cutter fixed mount, because hobboing cutter 5 has gear, hob head fixed block 6 also there is corresponding gear, so, when hob head 1 rotates, the gears meshing on the tooth on hobboing cutter 5 and hob head fixed block 6, hobboing cutter 5 is rotated, thus blade on hobboing cutter 5 can chip pencil; But because the hob head fixed block 6 of this type of penknife is fixed on housing 2 motionless, during chip, the number of turns that penknife handle 3 needs turn can be many, the rotating speed of hobboing cutter 5 is also comparatively slow, so chip efficiency is relatively low.
Summary of the invention
Technical problem to be solved by this invention is: the drive mechanism providing a kind of penknife that penknife chip efficiency can be made to improve.
For solving the problem, the technical solution used in the present invention is: a kind of drive mechanism of penknife, comprise and being connected and the hob head of synchronous axial system with penknife handle, described hob head is provided with hobboing cutter and hobboing cutter gear, hobboing cutter gear is external tooth, the outer ring being positioned at hob head driving end is fixedly connected with a driven wheel, described driven wheel be external tooth and with hob head synchronous axial system, the outer ring of described hob head driving end is also provided with a rotatable hobboing cutter driven wheel and a travelling gear, described hobboing cutter driven wheel and travelling gear are connected to a fixed and synchronous axial system, described hobboing cutter driven wheel and travelling gear are internal tooth, described travelling gear and the diameter of travelling gear corresponding with the position of driven wheel is greater than the diameter of driven wheel, an idle pulley is at least fixedly installed between described travelling gear and driven wheel, described idle pulley coordinates with the internal tooth of travelling gear and the external tooth of driven wheel respectively, described hobboing cutter driven wheel and diameter of hobboing cutter driven wheel corresponding with the position of hobboing cutter gear on hob head is greater than the diameter of hobboing cutter gear, the internal tooth of described hobboing cutter driven wheel matches with the external tooth of hobboing cutter gear.
Preferably, two idle pulleys can be provided with between described travelling gear and driven wheel.
Preferably, described hobboing cutter driven wheel and travelling gear can be formed in one.
Preferably, described hobboing cutter driven wheel and travelling gear can also be coordinated by assembling.
Preferably, described penknife handle and hob head can be threaded connection.
The invention has the beneficial effects as follows: the rotation of hobboing cutter driven wheel of the present invention accelerates the geared speed of hobboing cutter gear and hobboing cutter driven wheel internal tooth, thus accelerates the rotation of hobboing cutter, therefore improve the chip efficiency of penknife, and structure is simple.

Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, the invention will be further described.
As shown in Figure 2, the drive mechanism of described a kind of penknife, comprise and being connected and the hob head 2 of synchronous axial system with penknife handle 1, penknife handle 1 of the present invention is threaded connection with hob head 2, be threaded and install and manufacture homogeneous phase to convenient, described hob head 2 is provided with hobboing cutter 3 and hobboing cutter gear 4, hobboing cutter gear 4 is external tooth, the outer ring being positioned at hob head 2 driving end 21 is fixedly connected with a driven wheel 5, described driven wheel 5 be external tooth and with hob head 2 synchronous axial system, the outer ring of described hob head 2 driving end 21 is also provided with a rotatable hobboing cutter driven wheel 6 and a travelling gear 7, as shown in Figure 3, described hobboing cutter driven wheel 6 and travelling gear 7 are connected to a fixed and synchronous axial system, described hobboing cutter driven wheel 6 and travelling gear 7 are internal tooth, described travelling gear 7 and diameter of travelling gear 7 corresponding with the position of driven wheel 5 is greater than the diameter of driven wheel 5, an idle pulley 8 is at least fixedly installed between described travelling gear 7 and driven wheel 5, described idle pulley 8 coordinates with the internal tooth of travelling gear 7 and the external tooth of driven wheel 5 respectively, described hobboing cutter driven wheel 6 and diameter of hobboing cutter driven wheel 6 corresponding with the position of hobboing cutter gear 4 on hob head 2 is greater than the diameter of hobboing cutter gear 4, the internal tooth of described hobboing cutter driven wheel 6 matches with the external tooth of hobboing cutter gear 4, as shown in Figure 5.
The present invention does not do concrete restriction to the number of idle pulley 8, when preferentially selecting, be provided with two idle pulleys 8 between described travelling gear 7 and driven wheel 5, as shown in Figure 4, not only can not additionally increase too many cost but also the rotation of handle 3 can be made relatively lighter;
Hobboing cutter driven wheel 6 of the present invention and travelling gear 7 can be formed in one, one-body molded easily manufactured, easy for installation; Also can be coordinated by assembling, after hobboing cutter driven wheel 6 and travelling gear 7 wherein have one to be damaged, only need change the gear of damage, need not change simultaneously, decrease maintenance and repair cost comparatively speaking; Concrete condition can be determined according to specific needs.
During use, penknife handle 1 rotates, hob head 2 rotates with penknife handle 1 together, hobboing cutter gear 4 now on hob head 2 just starts to revolve round the sun around the center of hob head 2, and constantly engage with the internal tooth of hobboing cutter driven wheel 6 simultaneously, therefore hobboing cutter gear 4 also starts rotation, thus drives hobboing cutter 3 to start to rotate, and now just starts chip; Meanwhile, when penknife handle 1 rotates, driven wheel 5 drives the reverse of travelling gear 7 by idle pulley 8, therefore hobboing cutter driven wheel 6 also starts to reverse, and now, the rotation of hobboing cutter driven wheel 6 accelerates the geared speed of hobboing cutter gear 4 and hobboing cutter driven wheel 6 internal tooth, thus accelerates the rotation of hobboing cutter 3, therefore improves the chip efficiency of penknife.
