Abstract
Disclosed is a screwing-out type propelling pencil. A pencil lead can be stably and precisely controlled, and the screwing-out type propelling pencil can replace a wood pencil. According to the screwing-out type propelling pencil, a spiral drum is arranged in an outer shell, a sharp spiral line is arranged on the inner wall of the lower portion of the spiral drum, and the spiral line is tangential to one side of the surface of the pencil lead and can cut into the shallow surface of the pencil lead. The pencil lead is pushed out of a pencil point through cooperation of a lower sleeve ring and the spiral drum, the length of the pencil lead can be precisely controlled, and the pencil lead can be recovered.
Description
Technical field
A kind of writing implement using mechanical driven lead for retractable pencil, promotes the slow continuously and smoothly of lead for retractable pencil rotary-out type propelling pencil out in particular by rotation mode.
Background technology
The propelling pencil selling use in the market is made up of critical pieces such as shell, core pipe, chuck, spring, nibs substantially, lead for retractable pencil is clamped the conveying outward of a section a section by chuck and the linkage of core pipe, this structure is not easy lead for retractable pencil length adjustment to writing comparatively comfortable position, and the simultaneously recovery of lead for retractable pencil needs to prop up lead for retractable pencil with other thing and presses core pipe again and make chuck open could to regain lead for retractable pencil. Additionally this kind of pencil to hold the lead for retractable pencil of plurality of specifications, and nib outlet is set as allowing the bore of maximum lead for retractable pencil, so there will be the problem that lead for retractable pencil rocks when thinner lead for retractable pencil is write. Also has this type of pencil owing to using lead for retractable pencil more carefully can not reach the result of use that Wood pencil is write.
Summary of the invention
In order to solve the bad grasp of adjustment of existing sharpening core of propelling pencil, write lead for retractable pencil to rock and can not reach the problem that Wood pencil writes result of use, the present invention provides a kind of rotary-out type propelling pencil, this propelling pencil not only can precisely be looked after and guided pen core the best and be write length, conveniently reclaims pencil lead, and Wood pencil can be reached and write result of use, thus substitute Wood pencil completely.
The technical solution adopted for the present invention to solve the technical problems is: arrange spiral rotating cylinder in propelling pencil shell, rotating cylinder is by upper, lower collar is fixing in the enclosure, employing bias of portalling spiral rotating cylinder and lead for retractable pencil designs, the inwall of spiral rotating cylinder is provided with sharp-pointed spiral lines, spiral lines is tangent with lead for retractable pencil outer surface, when the lead for retractable pencil in spiral rotating cylinder prolongs and portals tenesmus in the middle of lower collar, the surface of the spiral lines incision lead for retractable pencil side of rotating cylinder inwall, by driving runner above spiral rotating cylinder away, rotate spiral rotating cylinder, spiral lines inside rotating cylinder promotes lead for retractable pencil to come downwards to needs length, rotating cylinder opposite direction rotates and then can be retracted in nib by lead for retractable pencil, the nib inner sleeve of micro-bullet effect it is provided with in nib, the internal diameter of inner sleeve is slightly less than the external diameter of lead for retractable pencil, so that it is more firm when lead for retractable pencil is write, more comfortable.
The present invention reaches to provide the benefit that: solve the deficiency of existing propelling pencil, reaches the result of use that Wood pencil is write, and substitutes Wood pencil.
Accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the present invention will be further described.
Fig. 1 is the front elevation view of the embodiment of the present invention
Fig. 2 is the side elevational view of the embodiment of the present invention
Fig. 3 is the A-A profile of Fig. 2
Fig. 4 is the B-B profile of Fig. 2
In figure: 1. shell, 2. lower collar, 3. cap hoop, 4. nib inner sleeve, 5. spiral rotating cylinder, 6. lead for retractable pencil, 7. go up the collar, 8. cap,
9. rotating cylinder runner
Detailed description of the invention:
Fig. 1 front elevation view can be seen that in showing that rotating cylinder runner (9) is positioned at the upper end of shell (1), cap hoop (3) is fixed on shell (1) top, cap hoop top is pressed on rotating cylinder runner (9) and prevents the upper shifting of spiral rotating cylinder (5), it is hollow in the middle of cap hoop (3), has cap (8) closure opening above.
Fig. 2 is side elevational view, and this figure has the profile of two embodiments to illustrate.
Fig. 3 A-A profile is the longitudinal sectional drawing of embodiment, figure can be seen that, lead for retractable pencil (6) is fixed on shell (1) center by nib inner sleeve (4), lower collar (2) and spiral rotating cylinder (5), nib inner sleeve (4) internal diameter is slightly less than lead for retractable pencil (6) diameter, the lead for retractable pencil it is thus possible to hold with a firm grip is so it does not rock, spiral rotating cylinder (5) is fixed by lower collar (2) and the upper collar (7), the center of circle of spiral rotating cylinder (5) and lead for retractable pencil (6) center of circle of portalling is in eccentric position, and spiral rotating cylinder (5) inner side spiral lines is tangent with lead for retractable pencil (6) side, surface; Rotating cylinder runner (9) and spiral rotating cylinder (5) are fixed as one, and cap hoop (3) middle plane props up rotating cylinder runner (9) upper end, and cap hoop (3) upper cap (8) blocks.
Fig. 4 B-B profile is one section of transverse cross-sectional view of embodiment, figure can be seen that, lead for retractable pencil (6) is fixed on shell (1) center by lower collar (2), spiral rotating cylinder (5) and lead for retractable pencil (6) are in eccentric position, the internal whorl of spiral rotating cylinder (5) is tangent with lead for retractable pencil (6) side, surface, and cuts the shallow top layer of lead for retractable pencil (6).
Claims (4)
1. a rotary-out type propelling pencil, shell arranges lead for retractable pencil and promotes device, it is characterized in that in shell, arranging rotatable spiral rotating cylinder, female thread structure is arranged at the bottom of rotating cylinder, rotate rotating cylinder, under the cooperation of female thread structure and lower collar, lead for retractable pencil is pushed out nib, reversely rotates, and lead for retractable pencil is retracted pen tip interior.
2. the rotary-out type propelling pencil according to claims 1, it is characterized in that: spiral rotating cylinder and lead for retractable pencil portal and be off structure, the spiral lines of spiral rotating cylinder inwall is tangent with the outer surface side of lead for retractable pencil, and can cut into the shallow surface of lead for retractable pencil, can promote lead core and tip inner sleeve comes and goes when rotating spiral rotating cylinder.
3. the rotary-out type propelling pencil according to claims 1, is characterized in that: the upper end of spiral rotating cylinder is provided with runner, runner some protrude from shell, it is simple to drive away with finger.
