Abstract
The utility model relates to a push-button full-automatic pencil which comprises a lead (1), a copper head (2), a lead-protection body (3), a spring I (4), a pointed sheath (5), a front cover (6), a locking pipe (7), a spring II (9), a clamping head (10), a lead-protection pipe (11), a lead-feeding pipe (12), an elastic rear stopper (13), a rear cover (14), a spring III (15), a baffle loop (16), a lead-storage pipe (17), a pen holder (18), a pen hanger (19), a hexagon (20), a press-head intermediate section, a press head and the like. The utility model is characterized in that the inner wall of a lead-clamped axial hole (25) of the clamping head (10) is smooth. The inner wall of the lead-clamped axial hole (25) of a prior full-automatic pencil clamping head (10) is spiral and easily abraded, and once the inner wall is abraded, the inside diameter of the axial hole increases, the lead-clamped ability of the clamping head (10) is weakened, when in writing, the pencil lead retracts and can not be used for writing, but the inner wall of the axial hole in the utility model is improved and cannot be easily abraded.
Description
Technical field
The utility model relates to full automatic pencil, relates in particular to pencil-lead and can give the knock-type full automatic pencil of mending automatically.
Background technology
Existing knock-type full automatic pencil is more convenient and time-saving than the Semi-propelling pencil of pressing pen top ability supply lead for retractable pencil.But when using, reality still has shortcoming: because the lead for retractable pencil chuck of existing full automatic pencil, the hole wall of its folder lead for retractable pencil is a screw thread, easy pinch off lead for retractable pencil, and the lead for retractable pencil screw thread that also can wear and tear, so that use a period of time, the chuck clamping force weakens, be difficult for clamping lead for retractable pencil, when consequently writing, contract in the lead for retractable pencil, can't write, finish service life.
Summary of the invention
The purpose of this utility model be to avoid above-mentioned weak point and provide the folder lead for retractable pencil power of chuck do not subtract for a long time not can the pinch off lead for retractable pencil the knock-type full automatic pencil.
The purpose of this utility model can reach by following technical solution: the utility model knock-type full automatic pencil, by lead for retractable pencil, protect core retainer plate, the point cover, the locking pipe, retaining core pipe, chuck, send the core pipe, back-up ring, fill in after the elasticity, protecgulum, bonnet, core storage tube, penholder, hexagonal, press in the head and save, press skull and spring I, spring II, compositions such as spring III, pressing skull cover connection presses in the head and saves, press joint cover connection hexagonal in the head, hexagonal cover connection core storage tube, fill in after the elasticity, bonnet, spring III snare send the core pipe, by the flange that send core Guan Yiduan, the back-up ring of the other end blocks, send core Guan Yiduan grafting core storage tube, the other end links with chuck by retaining core pipe, chuck be divided into two and half lobes close be embedded in locking pipe in, locking Guan Qianlian protecgulum, connection spring I before the protecgulum, connection protects core retainer plate before the spring I, and lead for retractable pencil runs through the central shaft hole of the utility model full automatic pencil, and the folder lead for retractable pencil shaft hole inner wall of chuck is an even surface.
The utility model advantage: chuck can the pinch off lead for retractable pencil, the long-term use, and its folder lead for retractable pencil power can not weaken, and prolongs pencil service life.

Fig. 2 is Fig. 1 critical piece structural representation.
Specific embodiments
As Fig. 1, shown in 2, the utility model is by a kind of knock-type full automatic pencil, by lead for retractable pencil 1, protect core retainer plate, point cover 5, locking pipe 7, retaining core pipe 11, chuck 10, send core pipe 12, back-up ring 16, fill in 13 after the elasticity, protecgulum 6, bonnet 14, core storage tube 17, penholder 8, hexagonal 20, press and save 21 in the head, press skull 22 and spring I4, spring II9, compositions such as spring III15, pressing skull 22 cover connection presses and saves 21 in the head, press joint 21 cover connection hexagonals 20 in the head, hexagonal 20 cover connection core storage tubes 17, fill in 13 after the elasticity, bonnet 14, spring III15 snare send the core pipe, by the flange that send core pipe 12 1 ends, the back-up ring 16 of the other end blocks, send the core pipe 12 1 end grafting core storage tubes 17, the other end links with chuck 10 by retaining core pipe 11, chuck 10 is divided into two and half lobes and closes and be embedded in the locking pipe 7, connection protecgulum 6 before the locking pipe 7, connection spring I4 before the protecgulum 6, connection protects core retainer plate before the spring I4, lead for retractable pencil 1 runs through the central shaft hole of the utility model full automatic pencil, and folder lead for retractable pencil axis hole 25 inwalls of chuck 10 are even surface.The sandwich power of 10 pairs of lead for retractable pencils 1 of chuck is produced by two and half lobes of chuck 10 lead for retractable pencil of closely filling the span of a man's arms, in case the folder lead for retractable pencil axis hole 25 of chuck 10 enlarges because of wearing and tearing, 10 pairs of lead for retractable pencils 1 of chuck are filled the span of a man's arms just not tight, its sandwich power promptly weakens, contract in the lead for retractable pencil when causing writing, can't write, existing folder lead for retractable pencil shaft hole inner wall is a screw thread, and screw thread is easy to wear, and folder lead for retractable pencil axis hole 25 inwalls of the utility model chuck 10 are even surface, than the difficult wearing and tearing of screw thread, thereby write for a long time and use the aperture not enlarge sandwich power not weaken, chuck 10 is made by PPS highly abrasion-resistant material, in addition, protect core retainer plate by ferrule 2, protecting core body 3 forms, metal is copper or stainless steel etc., and having now and protecting core retainer plate is the integral body that plastic material is made, its lead for retractable pencil port of export, easy to wear because of writing friction, change ferrule into, can obtain improvement.Steel ball 8 is seated in the cave 26, steel ball location of chuck 10, and cave 26 be oval, presses 22, presses that joint 21 can be made of one in the head, and point overlaps 5 grafting penholders 18,19th, pen hanging.
