Abstract
An automatic eraser pen comprises a columnar casing with two open ends. Springs are equidistantly arranged on the inner wall of the columnar casing; two semicircular clamp plates are arranged in the columnar casing and fixedly connected onto springs; an eraser strip adapting to the volume of a space formed by the two semicircular clamp plates is clamped between the semicircular clamp plates; a button is movable embedded to the end opening position of the semicircular clamp plate at an open end of the columnar casing; and the contact positions of the button 5 with the semicircular clamp plates 3 are in inverted circular jar shapes. The automatic eraser pen has the advantages of simple structure, high practicability, capability of being placed in a stationery case together with a pen body, convenience for carrying, and convenience in use as an eraser can be extended by a specified length only by pressing down the button.
Description
One, technical field
The utility model relates to a kind of rubber, particularly a kind of Automatic rubber pencil.
Two, background technology
In the actual life, existing rubber is because its volume is less, carrying inconvenience also is easier to lose, a kind of rubber pen is arranged now, be that lead for retractable pencil with general pencil changes eraser core into, need ream wooden shell, expose a rubber tip and be used for wiping with pocket knife, so just can reduce the contact area of rubber and paper, near the correct lines preventing from by mistake to wipe.This rubber carries more convenient, is the comparison difficulty but its drawback just is to cut wooden shell, and what be difficult for cutting is just right: cut oversizely, eraser core expose oversize will be very soft, be difficult to wiping; Cut to such an extent that too shortly can run low very much again, also will cut, very bothersome, because the loss rate of rubber is more faster than pencil.And to use pocket knife, if do not carry, just can't use this rubber pen.
Three, summary of the invention
The purpose of this utility model provides Automatic rubber pencil a kind of simple in structure, convenient and practical.
The utility model solves the technical scheme that the prior art problem is adopted: a kind of Automatic rubber pencil, the cylindrical shell that comprises both ends open, described cylindrical shell inwall equidistantly is provided with spring, be provided with two semicircle clamping plate in the described cylindrical shell, described semicircle clamping plate are fixedly connected on the spring, accompany the rubber bar that is suitable for two spatial volumes that semicircle clamping plate become between described two semicircle clamping plate, the semicircle clamping plate port activity of the openend of described cylindrical shell is embedded with button, and described button and semicircle fished joint synapsis are the rounding urniform.
The beneficial effects of the utility model are: the utlity model has simple in structure, practical, can in handwriting is put in writing case, be convenient for carrying and easy to use need press push button can make rubber stretch out the length of appointment, the convenient use.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, the specific embodiment
Below in conjunction with specific embodiment the utility model is described:
As shown in Figure 1, a kind of Automatic rubber pencil, cylindrical shell 1 described cylindrical shell 1 inwall that comprises both ends open equidistantly is provided with spring 2, be provided with two semicircle clamping plate 3 in the described cylindrical shell 1, described semicircle clamping plate 3 are fixedly connected on the spring 2, described two 3 on semicircle clamping plate accompany the rubber bar 4 that is suitable for spatial volume that two semicircle clamping plate 3 become, the semicircle clamping plate 3 port activities of the openend of described cylindrical shell 1 are embedded with button 5, and described button 5 is the rounding urniform with semicircle clamping plate 3 contact positions.
During actual the use, press the button, the bottom rounding urniform structure of button 5 can be oppressed two semicircle clamping plate 3 and be made between two clamping plate apart from becoming far away, at this moment put in from the bottom rubber bar 4, release button 5, two semicircle clamping plate 3 can be under the elastic force effect of spring 2 mutually near and clamp rubber bar 4, after the part of exposing when rubber bar 4 bottoms uses up, press the button 5, two semicircle clamping plate 3 can unclamp again, adjust the rubber bar 4 suitable distance that drops, 5, two semicircle clamping plate 3 of release button clamp rubber bar 4 once more again.
Above content be in conjunction with concrete optimal technical scheme to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
