Abstract

A double push type propelling pencil comprises a pencil holder, a pencil neck, a sharp sleeve, a press lead, a rotor, a coupling sleeve, a core sharp sleeve, a lead storage tube, a press button, a gripper, a clamp ring, a lead protection tube, a lead withdrawal spring, a core spring, a pencil clamp, a sheath and a damping ring. When in normal use, the press button is pressed to drive the lead storage tube, the press lead and the gripper to move forward till the clamp ring touches a stage arranged in the core sharp sleeve, at that time the gripper being relieved from the clamp ring and being open to let the lead extend out. When pressing is stopped, by the agency of the core spring the gripper retracts to match with the clamp ring and thereby the lead is gripped. When the press button is fully pressed down, the press lead drives the rotor to depart from three shallow grooves in a guide rail of the pencil neck, the rotor rotating across a certain angle and entering three deep grooves in the guide rail of the pencil neck by the agency of the lead withdrawal spring and the press lead bevel. When the press button is released, the whole core including the gripper, the lead protection tube and etc. withdraws to the plane stage of the guild rail in the pencil neck, at that time the core including lead protection tube withdrawing into the pencil neck.

Description

Two pressing propelling pencils

Technical field

The utility model belongs to the stationery field, specifically, relates to a kind of two pressing propelling pencil.

Background technology

The lead for retractable pencil of propelling pencil is thinner, and in use in order to make lead for retractable pencil be difficult for being fractureed, the front end of propelling pencil all is equipped with retaining core pipe.Usually the retaining core pipe of propelling pencil is divided into fixed and movable two kinds.Fixed retaining core pipe can be protected lead for retractable pencil effectively, and is also more stable when writing.But the retaining core pipe that exposes (needle tube type) is shouting pain hand or damage clothing easily; Though and movable retaining core pipe can be withdrawn in the point cover of propelling pencil in time spent not, guarantee safe in utilizationly, because movable retaining core pipe and sharp trepanning are gapped, are easy to generate when writing and rock, there is instability to feel.

Summary of the invention

The purpose of this utility model is to provide a kind of two pressing propelling pencil, by pressing ball-point pen structure is combined with propelling pencil, is maintained fixed the advantage of formula retaining core pipe and movable retaining core pipe.

For achieving the above object, the technical solution of the utility model is:

Two pressing propelling pencils comprise, penholder, and a neck, the one end is provided with each three of dark, shallow grooves pressing the structure guide rail with screw thread and penholder its inwall that links; Point cover is connected in a neck other end, one end inwall form supply back the core spring against step; Press core, be arranged in the neck, comprise first body and second body, one end outer edge bulge of first body forms a step, and leans with a neck, and other end outer wall is provided with convex tendon, and the end becomes dentation, also sheathed movement spring on this first body, and it is between step, convex tendon; Second body is connected in first body, one end, and its external diameter is less than first body; Runner, its outer wall is provided with convex tendon, and end one-tenth dentation, is sheathed on first body of pressing core, cooperates with the dentalation of the second body end; Coupling sleeve, its outer wall is provided with convex tendon, is sheathed on first body of pressing core, and one end and runner lean; The movement point overlaps, and is connected in the other end of coupling sleeve; Core storage tube is positioned at and is connected in penholder, a neck, and an end is connected in presses core, and the other end cooperates with the rubber seat; Press head and comprise, body, it is a hollow structure, and inwall is provided with a projection, forms two cavitys, and wherein an end is connected in the core storage tube end, and the other end is for placing the space of rubber; Lid is sheathed on body one end, and the other end stretches out penholder; Chuck, the one end is fixed in the end of pressing core second body, and cooperates with clamp ring; Clamp ring is sheathed on the chuck end; Retaining core pipe is arranged at the end that the movement point overlaps; Return the core spring, be sheathed on coupling sleeve, between the step of coupling sleeve convex tendon and point cover inwall.

In addition, described neck inwall is provided with and presses dark, the shallow grooves of structure guide rail for being provided with at interval.

Described neck inwall is provided with each three of dark, shallow grooves pressing the structure guide rail.

Again, the utility model propelling pencil also comprises pen clip, and this pen clip is arranged on the penholder.

The utility model propelling pencil also comprises sheath, and this sheath is sheathed on a neck outside.

With place, retaining core pipe end damped ring is housed also in the described movement point of the utility model propelling pencil cover.

The utility model propelling pencil is made the movement of propelling pencil more complete operable, at point cover front end fixed retaining core pipe is housed all, what similar pressing ball pen was equipped with in the outside of movement presses core and runner, match with guide rail and chute in the propelling pencil neck, when this pen does not use, the movement of propelling pencil comprises that fixed retaining core pipe all is retracted in the neck, guarantees safety; Only need press during use and press head with big slightly power, the point cover of propelling pencil movement is all stretched out outside the neck, and under the mating reaction of pressing core, runner, guide rail and time core spring, making it fixing, flicking is pressed head and is opened the interior chuck output lead for retractable pencil of movement then, reaches the purpose of use; Finish using return lead for retractable pencil in the retaining core pipe after, still only need press and press head with big slightly power, comprise that fixed retaining core pipe is all in the withdrawal neck pressing core, runner, guide rail and return the point cover that makes the propelling pencil movement under the mating reaction of core spring.

The beneficial effects of the utility model:

1. because more complete the having a style of one's own of movement of propelling pencil, solve movement flexible press serviceability and the quality that structure can not influence propelling pencil;

2. this structure has the spring of two kinds of different elastic force, as long as being in, the movement of propelling pencil do not have under the fixing situation, press arbitrarily and press head and only movement is slided up and down in penholder, and the chuck in the movement can not opened the output lead for retractable pencil, guarantee lead for retractable pencil and safe in utilization;

3. assemble very conveniently, the complete movement of penholder of only need outwarding winding just can be taken out easily.
