Engaged with the second delay gear 20 and drive the second delay gear 20 to move, then the second delay gear 20 is driven on contact block 13
Delay rack 21 do transverse movement, when SR switch 12 is in the groove 22, SR switch 12 resets, motor
4 stop starting, and hobboing cutter 7 completes light pen action during delay rack 21 does transverse movement, sets spring 24, contact block 13
It can reset, reliability is high, and stability is high.
The described lower surface of contact block 13 is provided with guide pad 25, and case 27, described case 27 are provided with described housing 1
The lower surface of support 26 is fixed on, described contact block 13 is located in case 27, and the described inner bottom surface of case 27 is along contact block 13
Moving direction is provided with guide groove 29, and described guide pad 25 is slidably fitted in guide groove 29, laterally moved in contact block 13
When play the guiding role.
The described inner bottom surface of case 27 is provided with support block 28, and described delay rack 21 is slidably fitted in the upper of support block 28
Surface, it is play the guiding role when contact block 13 laterally moves and ensures that delay rack 21 moves smooth, reliability with position-limiting action
It is high.
The described inner bottom surface of case 27 is provided with block 30, described block 30 and one of contact block 13 away from delay rack 21
Face is bonded, and is play the guiding role when contact block 13 laterally moves and position-limiting action.
The described upper surface of block 30, which is provided with, carries out spacing pressing plate 31, described pressing plate 31 to the upper surface of contact block 13
In the top of contact block 13, spacing up and down, reliability height is carried out to contact block 13.
The first described resetting-mechanism refers to that starting the lower end of axle 9 is provided with the open slot 32 that Open Side Down, described open slot
Spring 24 also is provided with 32, simple in construction, reliability is high.

Upper end is provided with and screws the top cover 39 on knife rest cover 36, and described switch actuating bar 38 is screwed when on knife rest cover 36 in top cover 39
It is connected with safety switch 35, reliability is high, and only top cover 39 is screwed on knife rest cover 36 using top cover 39 switch actuating bar 38
Motor 4 could be started by withstanding on safety switch 35.
Specifically, principle of the invention is to be placed on pencil hole 8 using pencil to turn down knife rest 2, because knife rest 2 is with opening
Moving axis 9 contacts, and knife rest 2 promotes startup axle 9 down to move, while starts the spring 24 below axle 9 and compressed, positioned at startup axle 9
On SR switch 12 mutually extruded with contact block 13, SR switch 12 is pressed, and motor 4 starts so that motor
Gear 5 rotates, and band moving gear 3 rotates, and knife rest 2 rotates with gear 3, and hobboing cutter 7 is made planetary cutting movement around pencil and cut
The nib of pencil processed, the nib of pencil is against on a resistance block 6 after having cut, and continues to press on knife rest 2, and now knife rest 2 drives a resistance block 6
Down move together, a resistance block 6 promotes delay axle 16 down to move, and the time-delay mechanism being delayed between axle 16 and contact block 13 opens
Move, that is, the first delay gear 18 on delay axle 16 is engaged with the second delay gear 20 by opening 19 and drives second to prolong
When gear 20 move, now be delayed axle 16 on spring 24 compressed, then second delay gear 20 drive contact block 13 on
Delay rack 21 does transverse movement, and now the spring 24 of contact block 13 is compressed, when SR switch 12 is in groove 22
When, SR switch 12 resets, and motor 4 stops starting, and hobboing cutter 7 completes light during delay rack 21 does transverse movement
Pen action, SR switch 12 resets after the completion of smoothing, and motor 4 stops operating, simple in construction, it is only necessary to a SR
Switch 12, it is possible to which the startup and delay for realizing motor 4 stop, and reliability is high, after the completion of light pen action, pencil from pencil hole
8 extract out, start the spring 24 on axle 9 due to being compressed, the bullet of startup axle 9 can be come up, start axle 9 and reset, and knife rest 2 also resets,
Be delayed axle 16 on spring 24 due to being compressed, also promote delay axle 16 up move resets, now first be delayed gear 18 and
Second delay gear 20 departs from, while the spring 24 on contact block 23, due to being compressed, contact block 23 resets, the first delay gear
18 and second delay gear 20 depart from and ensure that delay rack 21 and second is delayed 20 smooth rotation of gear, SR switch 12 is simple
Be exactly for list one kind can with automatically reset switch, reset switch can be it is cylindrical or square etc., in shape
It and common switch do not have what difference, but functionally different, the difference of reset switch and self-lock switch：Reset is opened
After pass presses down, hand, which unclamps, replys original state；Self-lock switch unclamps hand after pressing down and not replied, and reset switch is opened with crawl
Close much like, strictly it is also one kind of point driving switch, but reset switch resets unlike common point driving switch and opened
The seed selection of pass is longer, and contact is not a point, but a stroke, and the side of knife rest 2 is provided with the first open slot, guide rod 17 and resistance pen
Block 6 is located in the first open slot, start the nearly gear 3 in the outer surface of axle 9 one end be provided with limited block 41, to startup axle 9 carry out it is spacing,
Prevent that startup axle 9 is up mobile too many.
Specifically, knife rest 2 be located at the part in through hole 10 cross section it is generally rectangular cross-section, preferably square, ensure knife
Frame 2 can be slidably fitted in through hole 10 can also rotate with gear 3, start axle 9 and moved up and down due to only needing, start axle
The crossbearer face of 9 part in through hole 10 is circle, and the catercorner length of rectangle is more than circular diameter, while in through hole 10
