Description

素描专用卷笔刀
技术领域
本实用新型涉及一种卷笔刀,特别是公开一种素描专用卷笔刀。
背景技术
目前,公知的卷笔刀由基座、基座上的卷笔锥桶、刀片和固定刀片用的螺丝组成,其卷笔锥桶的底面最大圆直径为0.75~0.85cm,刀片的长度为2~3cm,卷削铅笔时,削出来的铅笔笔头锥体部分较短,只能满足写字用铅笔的削笔需求,而无法满足素描用铅笔的削笔要求。素描写生时一般使用横握的握笔方式,为避免横卧时笔杆头会摩擦画面,因此相应要求铅笔笔头的锥体长度较写字用铅笔的长。由于目前的卷笔刀是为写字铅笔而设计的,因此素描铅笔无法使用现有技术中的卷笔刀,只能采用刀具进行手工削制。
发明内容
本实用新型的目的是解决现有技术中卷笔刀只能满足写字用铅笔的削笔的问题,提供一种满足素描用铅笔削笔要求、高效、安全的素描专用卷笔刀。
本实用新型是这样实现的:一种素描专用卷笔刀,包括基座、基座上的卷笔锥桶、刀片和刀片固定器,所述刀片的长度等于卷笔锥桶的锥边长度,所述卷笔锥桶的底面最大圆直径为0.75~0.85cm,所述刀片的长度为大于3cm小于5.5cm。
所述刀片固定器还包括:刀片两端设有卡槽,所述基座上设有能嵌在上述刀片两端卡槽里的卡点,以起到固定刀片,避免刀片在卷削铅笔时发生移动的作用。
本实用新型的有益效果是:避免了刀具的使用,减少安全隐患,使得在削素描铅笔时更加高效、安全。
附图说明
图1是本实用新型刀片示意图;
图2本实用新型结构示意图。
图中:1、卡槽;2、卡点;3、基座;4、卷笔锥桶;5、刀片。
具体实施方式
根据图1、图2,本实用新型包括基座3、卷笔锥桶4、刀片5,刀片5两端分别设有卡槽1,基座3上设有用于卡住卡槽1的卡点,以增加刀片5在基座上的牢固度。刀片5的长度等于卷笔锥桶4的锥边长度,卷笔锥桶4的底面最大圆直径为0.75~0.85cm,刀片5的长度为大于3cm小于5.5cm。相对于现有技术,在卷笔锥桶4的底面最大圆直径保持不变的情况下,本实用新型增加了刀片5的长度,并相应增加卷笔锥桶4的锥边和锥高的长度,从而使削出的铅笔笔头的锥体较长,符合素描用铅笔的削笔要求。
