Abstract
The utility model relates to a telescopic pencil shell, which is designed for solving the technical problems of poor stability of adjusting way and single structure of similar products in prior arts. A shell body of the telescopic pencil shell comprises a front cover, a pencil body and a rear screw; and the pencil body is of a cylinder shape. The key points of the telescopic pencil shell comprise the facts that the front cover is arranged at one end of the pen body and is of a cone shape; the rear screw is arranged in the pencil body; the inner diameter of the pencil body is in threaded connection with the outer diameter of the rear screw; and a center shaft in the rear screw is provided with a gel pen refill hole. A short pencil stub is fixed in the pencil body through the front cover and the rear screw and also can be replaced with a gel pen refill, and the gel pen refill extends in the gel pen refill hole in the rear screw. The telescopic pencil shell is reasonable in structural design, convenient to use, good in stability, multiple in uses and novel in appearance, and is suitable for the extended use of the short pencil stub, the use of a gel pen and the structural improvement of the similar products.
Description
Technical field
The utility model relates to the pencil pen cap, is a kind of telescopic pencil shell.
Background technology
Pencil is that a kind of pen core adopts graphite material to process, and the writing implement that a body adopts wood materials to process is a type of pen.After need layer of wood being pruned through instruments such as pencil-knifes when it uses, make the graphite pen core expose pen and can use after one's death; But in use often since the wood materials of a body prune too much, only stay short nib, and difficulty grips and writes.For this reason, like the patent No. ZL200720091043.0 that discloses in the Chinese patent document, July 9 2008 Granted publication day, utility model title " pencil stub lengthening cover "; This pencil stub lengthening cover main feature is that the socket end at the pencil shaft overcoat is provided with the pencil cranse, uses the hand adjustment bolted, and pencil cap is fastened on the socket of overcoat, and the pencil cranse can be fixed on length pencil (pencil stub) in the overcoat.The mode less stable that the mode of above-mentioned cranse locking pencil stub and like product sleeve prolong pencil stub is subjected to displacement pencil stub stressed after big easily; This type of product function is comparatively single simultaneously.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of the utility model is to this area a kind of screw adjusting, multiduty telescopic pencil shell to be provided, and makes it solve existing like product regulative mode poor stability, the technical problem that structure is single.Its objective is and realize through following technical scheme.
A kind of telescopic pencil shell, the housing of this pencil shell comprise protecgulum, a body, back screw rod, and a body is cylindrical; Its structural design main points are that an end of said body is provided with protecgulum, and protecgulum is tapered, are provided with the back screw rod in the body, are threaded between the external diameter of the internal diameter of a body and back screw rod.Open protecgulum, in a body, put into the short pencil head, the short pencil head is fixed in the body through the tapering point of protecgulum, prevents that the short pencil head from dropping out a body when using; Then, make the nib of short pencil head stretch out protecgulum, promptly prolong the length of short pencil head through a body through the back screw rod in the pen with rotary body.The profile of this pencil shell is syringe-type.
Central shaft in the screw rod of said back is provided with the Neutral ball-point for ball-point pen hole.The tip of the brushstyle of a writing or painting circle of Neutral ball-point for ball-point pen is fixed in a body through protecgulum, and Neutral ball-point for ball-point pen penetrates a body and back screw rod, and this pencil shell promptly can be used as gel ink pen and uses; Simultaneously, through back screw rod moving in a body, the length of adjustment housings.
The utility model reasonable in design, easy to use, good stability, purposes is various, and profile is novel; The prolongation that is applicable to the short pencil head is used and is used as gel ink pen, and the architecture advances of like product.

Fig. 2 is the improved structure sketch map of Fig. 1.
Fig. 3 is the Neutral ball-point for ball-point pen user mode structural representation of Fig. 2.
Figure number and title: 1, protecgulum, 2, the short pencil head, 3, a body, 301, the Neutral ball-point for ball-point pen hole, 4, the back screw rod, 5, Neutral ball-point for ball-point pen, 501, tip of the brushstyle of a writing or painting circle.
The specific embodiment
Combine accompanying drawing at present, to the structure of the utility model with make as further describing.Embodiment as shown in Figure 1, the protecgulum 1 of this pencil shell is connected with an end of a body 3, screws in back screw rod 4 in the other end of a body, is threaded between the external diameter of the internal diameter of a body and back screw rod; Above-mentioned protecgulum, a body, back screw rod are formed housing, and said body is cylindrical, and protecgulum is tapered.During use, open protecgulum, in a body, put into short pencil head 2, the protecgulum of screwing, short pencil head are fixed in the body; Then through the back screw rod in the pen with rotary body, make the nib of short pencil head eject protecgulum, said short pencil head gets final product installation, and after a body of length prolongs, is used to write.
Like Fig. 2, shown in Figure 3, the foregoing description is carried out architecture advances, promptly the central shaft in the screw rod of back is provided with Neutral ball-point for ball-point pen hole 301.Said structure improves the prolongation that does not influence the short pencil head and uses; Simultaneously, when this pencil shell uses as gel ink pen, take out the short pencil head in the body, put into Neutral ball-point for ball-point pen 5 in the body, the tip of the brushstyle of a writing or painting circle 501 of Neutral ball-point for ball-point pen is the same with existing Neutral ball-point for ball-point pen, is held between a body and the protecgulum, and this gel ink pen can use.
