Here is omitted.
Referring to Fig. 1 to Fig. 8, the operational approach that the rotary and telescopic that above-described embodiment is provided cuts lead pencil is as follows：
Tail is turned penholder 1 to turn clockwise on earth, now the clamping outer tube 9 of lead for retractable pencil grip block 2 is withstood on placket 7, due to
Outer cylinder diameter and outer cylinder diameter more than cored inner core 10 of the interior barrel dliameter of placket 7 less than clamping outer tube 9, so 10 meeting of cored inner core
Move forward, therefore the spring 8 at middle part can compress, due to without the clamping effect for clamping outer tube 9,10 meeting of cored inner core
As the opening of both sides opens, as shown in figure 3, lead for retractable pencil 15 put in cored inner core 10 from written mouth again, then that tail is turned penholder 1 is inverse
Hour hands rotate, and lead core gripper can be driven to move to the opposite direction of nib, and make clamping outer tube 9 to nib from the elastic force of spring 8
Direction is moved, and so as to clamp lead for retractable pencil 15, reaches suitable length to lead for retractable pencil head as shown in Fig. 2 continuing rotate counterclockwise tail and turning penholder 1
Degree；
When nib writes flat needs to carry out cutting, tail is turned into 1 rotate counterclockwise of penholder first, core device 11 is stretched into lead for retractable pencil head
Inside, then the slide block 121 connected on propelling sleeve 12 is slid into 42 bottom of chute of L-shaped to written direction, then slide to L-shaped
42 the right notch of chute is locked, during drive propelling sleeve 12 to written end motion so that core device from slide block 121
11 close up tapered, as shown in figure 4, then rotating clockwise tail turns penholder 1, when lead for retractable pencil 15 also rotates with advance and core device
Can be carried out cutting lead during 11 contact；
Cut after lead terminates, slide block 121 slid back to into home position along chute 42, now propelling sleeve 12 is moved therewith backward,
No longer extruded core device 11 will be returned to open configuration due to its own resilient, as shown in figure 5, being further continued for turning clockwise
Tail turns penholder 1, makes lead for retractable pencil be retractable to appropriate length to the outside of written mouth, you can be operated.
