The specific embodiment:

See shown in accompanying drawing 1～accompanying drawing 3, present embodiment by lead for retractable pencil 1, retaining core pipe 2, sleeve pipe 3, retaining core pipe spring 4, retaining core pipe end socket 5, damping 6, send lead for retractable pencil spring 7, steel ball 8, lock tube 9, card spring 10, card 11, lock tube seat 12, back-moving spring 13, capping 14, lead core pipe 15, lead core base 16 and combine.

Referring to accompanying drawing 1 as can be seen " full automatic pencil machine core " be cylinder, the center is a lead for retractable pencil 1.Lead for retractable pencil 1 passes retaining core pipe 2 dampings 6 cards 11 always and leads core pipe 15 and lead core base 16 at the center.Retaining core pipe 2 is installed in the front end of sleeve 3, can do axially and move flexibly.Retaining core pipe spring 4 is installed in the rear end of retaining core pipe 2, and retaining core pipe spring 4 is positioned in the retaining core pipe end socket 5.Send lead for retractable pencil spring 7 to be installed between retaining core pipe end socket 5 and the lock tube seat 12.Steel ball 8 is in the groove of totally two both sides that are installed in card 11, can be flexibly in lock tube 9 inclined-plane axially roll, lock tube 9 is installed in the front end of lock tube seat 12.Card spring 10 is installed between lock tube 9 and the card 11.Lock tube seat 12 rear ends are by capping 14 location, and lock tube seat 12 can axially move in sleeve 3 flexibly.Lead core pipe 15 and be installed in the front end of leading core base 16, stretch out part and be inserted in the back stomidium of card 11.Back-moving spring 13 is installed in leads between core base 16 and the lock tube seat 12.Capping 14 designs have assembling self-locking position, directly assemble with sleeve 3, get final product auto lock.

With reference to accompanying drawing 2 the present invention according to the explanation of first adding lead for retractable pencil; Put into lead for retractable pencil from leading core base 16, lead for retractable pencil drops in the circular hole of the rear end of card 11 by leading core pipe 15.Because the chucking of card 11 partly will be urinated in chucking lead for retractable pencil 1, so lead for retractable pencil 1 can't pass than the diameter of lead for retractable pencil 1.Press and lead core base 16 and the bigger back-moving spring 13 promotion lock tube seats 12 of elastic force, together with lock tube 9, the downward together less lead for retractable pencil spring 7 that send of compression elasticity of steel ball 8, card 11 and lead for retractable pencil 1 stops to spacing place.Continue to push and lead core base 16, because lock tube seat 12 is place, location halted state, lead core pipe 15 and be inserted in and continue in the circular hole of card 11 downwards, promoted card 11 and moved down, formerly abutted against in the lock tube 9 on the inclined-plane to the steel ball 8 of card 11 both sides of pulling by card spring 10.Move down through leading 15 actuating cards 11 of core pipe, steel ball 8 moves to the inclined-plane general goal, and card 11 has just separated both sides.Because card 11 openings make card 11 front hole enlarged diameter, lead for retractable pencil 1 has dropped to the top in damping 6 holes smoothly.Lead for retractable pencil 1 has stopped again advancing.The rubber raw materials of damping 6 makes damping 6 existing big friction that fine elasticity be arranged again.Automatically send core when damping 6 is write in order to reach, wear to pass by so lead for retractable pencil 1 is provided with pressure less than lead for retractable pencil 1 diameter in the hole of damping 6.Owing to push and lead core base 16 on earth.Have only earlier and unclamp, carry out again pushing the second time.Card 11 when unclamping, steel ball 8, and lock tube seat 12 is led core pipe 15, leads core base 16, has got back to original position under the promotion of back-moving spring 13.First step card 11 when push the second time of carrying out has tightened lead for retractable pencil 1 and has sent into damping 6.Delivered to outside the retaining core pipe 2 through the lead for retractable pencil 1 of pushing several times of one-way only operation several times like this.Finished the functional requirement of sending lead for retractable pencil 1 smoothly.

Automatically going out plumbous principle with reference to accompanying drawing 3 the present invention when writing elaborates: when retaining core pipe 2 is subjected to writing problem when writing, pressure retaining core pipe 2 has been run into stressed retraction on the paper, during retaining core pipe 2 retraction because lead for retractable pencil 1 is subjected to card 11, lock tube 9, the unidirectional function that tightens of steel ball 8 can not be return, and this also is an important indicator of propelling pencil: clamping force.When writing pressure relieve or not having, retaining core pipe 2, damping 6 is got back to original position under the promotion of retaining core pipe spring 4, lead for retractable pencil 1 comes out to having set aside one section because the friction of damping 6 and the effect of aperture elastic force have been held with a firm grip, and lock tube 9, steel ball 8, the one-way performance of card 11 is downwards an opening mode to lead for retractable pencil 1, therefore lead for retractable pencil 1 has been transferred in damping 6 smoothly, has finished to go out plumbous task for the first time automatically.Because constantly lifting pen when writing writes with starting to write.Therefore the present invention's " full automatic pencil machine core " is exactly the intermittent pressure that has utilized when writing.Accomplished to go out automatically lead, and the just right abrasion that replenished lead for retractable pencil have reached designing requirement.

The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
