Abstract

一种改进的粉笔握笔器,它除具有内套、外套和 弹簧外还具有其两翼凸台穿过内套槽孔与外套内壁 螺纹套接的滑块,通过旋转外套带动滑块顶出粉笔头 并控制粉笔移动的位置,从而使之具有可使粉笔随意 顶出或退回,书写时粉笔位置稳定、使用方便的特 点。

Description

本实用新型是一种改进的粉笔握笔器。
已知的市售粉笔握笔器产品由内套、外套和装置在内套外壁台阶与外套内壁台阶之间的弹簧组成,其中内套朝向粉笔的一端套口呈梳针形。该产品解决了使用者直接手接触粉笔的不清洁、不卫生问题,但粉笔头单纯靠压迫内套顶出,由于缺少定位装置,粉笔头顶出后容易复位,使用很不方便。
本实用新型的目的是提供一种改进的粉笔握笔器,使用这种握笔器能随意移动并控制粉笔的位置,十分方便。
本实用新型的粉笔握笔器是这样改进的,在上述粉笔握笔器的内套1两侧对应开凿轴向槽孔5并在内套1内装置可在套内自由移动的滑块4,滑块4对应槽孔5设有与槽孔尺寸匹配的两翼凸台7,该两翼凸台分别穿过内套1两侧槽孔5与外套2内壁螺纹套接。由于滑块4与外套2螺纹套接,当旋转外套时,外套内螺纹传递的力矩即推动滑块旋转位移,外套转动的方向不同,滑块移动的方向也随之不同,因此插入套内的粉笔可通过滑块在旋转外套产生的作用力推动下顶出或退回。而外套停止转动,则滑块静止并因螺纹的阻碍不能上下移动而保持原位,插入的粉笔亦随之不能移动。
下面结合附图对本实用新型加以进一步说明。
附图为本实用新型粉笔握笔器一个具体实施例的结构示意图,其中1-内套,2-外套,3-弹簧,4-滑块,5-槽孔,6-空腔,7-凸台。
附图所示的粉笔握笔器包括一塑制内套1、外套2和装置在内套外壁台阶与外套内壁台阶之间的弹簧3、具有两翼凸台7的滑块4。内套1两侧对应开凿有轴向槽孔5且朝向插置粉笔的一端套口呈梳针形,滑块4由其两翼凸台7穿过内套1槽孔5与外套2内壁螺纹套接。为了使插入内套1的粉笔具有更好的稳定性,在滑块4朝向粉笔的一端制成具有与普通粉笔头大小匹配的内圆柱形空腔6。由此构成的粉笔握笔器具有可使粉笔自由顶出或退回、书写时粉笔位置稳定,使用方便的特点。

Claims (2)
