Abstract
The utility model relates to a propelling pencil which belongs to the technical field of stationery and is used for providing a design scheme that a lead cord can be regulated continuously and a propelling pencil has the advantages of simple structure and convenient use. The structure of the utility model is composed of a pen rod, a pen mouth, a core regulating rotary rod and a movable lead cord clamping sleeve, wherein, the pen rod is a hollow circular tube of which the inner circumference is provided with screw threads, and screw threads which are meshed with the inner screw threads on the pen rod are arranged on the outer circumference of a spiral tube; a lead cord clamping mouth forms a cylinder shape and is positioned in the hollow tube of the spiral tube, and the front end of the lead cord clamping mouth is provided with an elastic hole for clamping and holding a lead cord; the back part of the lead cord clamping mouth is provided with a longitudinal bulge which is connected with the inner tube wall of the spiral tube, and the core regulating rotary rod is a hollow circular tube which is provided with a long-striped gap along the longitudinal axis of the tube; the movable lead cord clamping sleeve is inserted in the hollow circular tube of the core regulating rotary rod. Users only need to rotate a rotary cap on the back end of the core regulating rotary rod, and the core regulating rotary rod can drive the movable lead cord clamping sleeve to move fore-and-aft in the pen rod so as to regulate the extended length of the lead cord on the pen mouth point. Because the regulation depends on screw threads, the utility model can achieve the aim of fine regulation.
Description
Technical field
The utility model relates to a kind of propelling pencil, belongs to the stationery technical field.
Background technology
Advantages such as Writing instrument has varied, and pencil is still inexpensive with it in numerous writing implements, correction is convenient are used widely, particularly indispensable especially writing implement in pupil's study.Pencil also has multiple propelling pencil except traditional Wood pencil, it is numerous that its structure has letter to have, and pluses and minuses are respectively arranged, and price also has no small difference, and wherein, most widely used is a kind of propelling pencil of push type output lead for retractable pencil.This propelling pencil is whenever pushed, just makes lead for retractable pencil spue one section from nib, pushes continuously, just can adjust reveal lead for retractable pencil to suitable length.But this structure, the adjusting of lead for retractable pencil are unit change with the section, can't accomplish continuous variation, particularly when needs are finely tuned.
Summary of the invention
Technical problem to be solved in the utility model provides a kind ofly can adjust lead for retractable pencil, propelling pencil simple in structure, easy to use continuously.
The technical scheme that addresses the above problem is: a kind of propelling pencil, it is by penholder, mouth, transfer the core swing arm, movable lead for retractable pencil chuck is formed, described penholder is a hollow circular tube, its inwall is provided with screw thread, described movable lead for retractable pencil chuck is made of helix tube and lead for retractable pencil dop, helix tube is the short pipe of hollow, its excircle is provided with the screw thread that matches with the internal thread of penholder, the lead for retractable pencil dop is a cylindrical shape, be positioned at the hollow tube of helix tube, its front end is provided with springhole clamping lead for retractable pencil, and back segment raises up and is connected with the inner tubal wall of helix tube, leaves the gap between the inwall of cylinder body wall other parts and helix tube; Described accent core swing arm is a hollow circular tube, and there is a rectangular gap on the top of pipe from the longitudinal axis of the mouth of pipe to the pipe tail along pipe, and the width of gap is slightly larger than the width of the projection on the lead for retractable pencil dop, and described movable lead for retractable pencil chuck is inserted in the hollow circular tube of transferring the core swing arm.
Above-mentioned propelling pencil, the right part of described accent core swing arm connects a turncap, and turncap is enclosed within on the penholder, and the excircle of its internal diameter and penholder is complementary.
Above-mentioned propelling pencil, a described penholder and a mouth place connect for spiral between the two for dividing body structure.
Above-mentioned propelling pencil, the width of the projection on the described lead for retractable pencil dop is the 2-3 millimeter.
Adopt the propelling pencil of this structure, have simple in structure, easy to use and non-damageable advantage.The user only need rotate the turncap of transferring core swing arm rear portion, and transfer the core swing arm will drive movable lead for retractable pencil chuck and in penholder, move forward and backward, thus the length of regulating a lead for retractable pencil that stretch out at the mouth place, because this adjusting is by threaded adjusting, so can reach the purpose of fine setting.

The specific embodiment
As we can see from the figure, major part of the present utility model is penholder 1, movable lead for retractable pencil chuck and transfers core swing arm 3.Penholder 1 is a hollow circular tube, and circumference is provided with internal thread within it.Movable lead for retractable pencil chuck is made up of helix tube 5 and the lead for retractable pencil dop 4 that is attached thereto, and helix tube 5 also is a tube, but its length is much smaller than the length of penholder 1, and its excircle is provided with screw thread and matches with the internal thread of penholder 1.Lead for retractable pencil dop 4 is little cylindrical shapes, and its left end has a springhole, can clamp lead for retractable pencil 6, and right end portion is connected with helix tube 5.Connected mode is to be provided with a projection 8 on the top of small cylinder, and its width is the 2-3 millimeter, and this projection 8 is connected with the inwall of helix tube 5, and formation one annular gap, centre of cylindrical remainder and helix tube 5 encloses 10.Transferring core swing arm 3 is hollow circular tubes, is provided with a rectangular gap 9 along the top y direction of pipe, and the width of gap 9 is identical with protruding 8 width.
During use, lead for retractable pencil 6 usefulness lead for retractable pencil dops 4 are clipped, movable lead for retractable pencil chuck is put into penholder 1, make helix tube 5 and the engagement of penholder 1 internal thread from the rear of penholder 1.Then the gap 9 of transferring core swing arm 3 is aimed at connection bump 8 places of lead for retractable pencil dops 4 and helix tube 5, is allowed and pass the annular gap circle 10 of other parts among helix tube 5 of transferring core swing arm 3, so just can accent core swing arm 3 insertion penholders 1 in.Rotation transfers core swing arm 3 just can drive helix tube 5 and lead for retractable pencil dop 4 rotates together, and helix tube 5 is rotated along the internal thread of penholder 1, moves forward and backward thereby drive lead for retractable pencil dop 4, and lead for retractable pencil 1 can stretch out or indentation from a mouth 2, and is very easy to use.Penholder 1 of the present utility model is that spiral is connected with a mouth 2, also can be made into plug-in or other connected modes certainly.Transfer the affixed turncap 7 in rear portion of core swing arm 3, rotate turncap 7 accent core swing arm 3 is rotated.
