Abstract
The utility model relates to a propelling pencil, in particular to a pencil, with longitudinal open slots on the casing to ensure that a pencil core can be fed in a sliding manner. The propelling pencil comprises a pencil holder; a hollow inner chamber is formed in the pencil holder; a pencil lead is arranged in the inner chamber of the pencil holder; open slots are formed longitudinally on at least two sides of the pencil holder; the open slots are communicated with the inner chamber; a sliding clamp is sleeved on the pencil holder; a clamping platform is arranged at the lower end of the sliding clamp and is positioned in the open slots and can move along the open slots; and the pencil lead is tightly clamped by the clamping platform, so that the clamping platform can drive the pencil lead to slide synchronously. The utility model has the advantages of simple structure, convenient use, wood saving and low cost. The utility model has the benefits that the pencil core is less susceptible to fracture and contraction; the utility model is competent to replace a wooden pencil with a thick pencil lead or a propelling pencil; and the utility model makes the best of the pencil lead.
Description
Technical field
The utility model relates to a kind of propelling pencil, relates in particular to a kind of pencil by the method feeding pen core that slides in the shell of vertical fluting.
Background technology
Pencil has other incomparable correction advantage easily, is also used drawing tools such as particularly indispensable writing implement in pupil's study, and drawing, drawing up to now widely.Pencil is the most common, the most popular a kind of stationery.
Existing pencil kind is a lot, generally is divided into the Wood pencil and the slide core pencil of fixed core.The Wood pencil of fixed core has simple in structure, easily manufactured advantage, uses inconvenient defective but it has, and the pen core of pencil is being coated by wooden, needs cutting in the time of use, and is pretty troublesome.And the manufacturing of Wood pencil expended a large amount of timber resources, is unfavorable for the protection of environment.The chip that chips away in addition also severe contamination around environment.The slide core pencil has advantage easy to use, and general its structure of existing slide core pencil is made up of the shaft of a writing brush, nib, spring, collet, the cap for brush etc., and pen core is fixed by collet, by pressing the cap for brush pen core is stretched out in collet.After long-time use of this pencil process, collet will become flexible, the tight pencil-lead of folder, and the pen core of exerting oneself a little when causing writing can't be write with regard to sliding backward retraction.The pencil that adopts the chute structure is also arranged, but pen core was difficult for fixing after the pencil of this structure used a period of time, pen core can rock or withdraw when writing.
The utility model content
Technique effect of the present utility model can overcome above-mentioned defective, and a kind of propelling pencil that prevents that lead for retractable pencil from sliding is provided, and it is simple in structure, and cost is low.
For achieving the above object, the utility model adopts following technical scheme: it comprises penholder, and the end of penholder is a nib, and the penholder inner hollow forms inner chamber, and lead for retractable pencil is housed in the inner chamber; On the penholder at least both sides longitudinally be provided with open slot, open slot is communicated with inner chamber; Being with on the penholder slides blocks, and the Ka Tai of the card that slides is positioned at open slot and can slides along open slot, and Ka Tai slides lead for retractable pencil chucking and drive lead for retractable pencil synchronously.
Inner chamber and open slot can be provided with multiple mode: 1, be provided with open slot except that leaving a bit of integral body on the penholder, the card that slides can slide along open slot; 2, only be provided with open slot near a section of nib on the penholder, the Ka Tai of the card that slides is positioned at open slot and can slides along open slot, even very short still can the passing through of lead for retractable pencil surplus blocks the platform clamping like this, not only save lead for retractable pencil, and effectively fixing lead for retractable pencil; 3, penholder inside is only forming inner chamber near the part hollow of nib, on the penholder of inner chamber correspondence at least both sides longitudinally be provided with open slot, the penholder more than the inner chamber all is solid, durable in use like this; 4, above-mentioned the 2nd kind of mode, the penholder inner chamber by space bar be divided between the upper and lower every two sections, standby lead for retractable pencil is housed in the epimere inner chamber, after lead for retractable pencil used up, the inner chamber of directly standby lead for retractable pencil being packed into got final product like this.
Curve inwardly in the middle of the card platform, be bell mouth shape.Ka Tai is provided with two at least.The nib end is provided with opening, and open circumferential is provided with vertical breach, and nib is provided with screw thread, and nib is provided with outward and nib fastening cap supporting, by being threaded.Vertically the breach section is rectangle or trapezium structure, adopts which kind of structure and several breaches are set and decide according to concrete operating position, as long as guarantee can tighten lead for retractable pencil when breach inwardly shrinks, prevents that the lead for retractable pencil slip from getting final product.For guaranteeing that the screw thread between nib and the fastening cap closely cooperates, nib comprises terminal cone and the cylinder that is connected with penholder, and screw thread is arranged on the cylinder.
During use, screw thread between fastening cap and the nib is screwed, the card that slides is moved on to the top of open slot, unclamp the screw thread between fastening cap and the nib, the card that slides that moves down, the slip cassette tape moves the same moved further of lead for retractable pencil, lead for retractable pencil is adjusted to suitable length, screw the screw thread between fastening cap and the nib, make the fastening location of lead for retractable pencil, directly write and get final product.After the lead for retractable pencil of naked leakage used up, the card that will slide after moving up a segment distance along open slot unclamped the screw thread between fastening cap and the nib, lead for retractable pencil is adjusted to suitable length after, screw fastening cap and nib between screw thread get final product.After using up, lead for retractable pencil can use standby lead for retractable pencil; After all lead for retractable pencils use up, open the cap for brush, reload lead for retractable pencil and get final product.When lead for retractable pencil is installed, fastening cap is unscrewed or takes off, lead for retractable pencil is got final product along middle insertion of card platform,, can very easily lead for retractable pencil be inserted in the inner chamber because Ka Tai is bell mouth shape.
The utility model is simple in structure, and is easy to use, and pen core not frangibility and synthlipsis goes back, and can substitute wooden lead bullion pencil and propelling pencil fully, makes full use of lead for retractable pencil, save timber resources, and cost is low.
