此作品是根据传统木工制作时所用的手工轻钻孔器演变而来的。其原理是借助左右拉动绳子、带动钻杆旋转、产生摩擦力,使钻头逐步钻穿木板或者竹板。我们借其原理,结合孩子的特点与能力改装成孩子感兴趣的操作玩具一“魔钻”。此作品主体材料是采用废旧木材改装而成,成本低、牢固且便于操作,固定转盘上的活动转盘材料能随意更换。既经济实惠、牢固、便于操作又能锻炼孩子的动手操作能力,激发孩子探索各种科学现象的兴趣。此玩具功能多变,
This work evolved from a hand-made light drill used in traditional carpentry. The principle is that by pulling the rope around, the drill rod is driven to rotate to generate friction, so that the drill bit gradually drills the wooden board or the bamboo board. We borrow its principle, a combination of the child’s characteristics and ability to be converted into a toy “magic diamond” interested in children. The main body of this work is made from discarded wood, which is low cost, firm and easy to operate. The material of the movable turntable on the fixed turntable can be freely changed. It is economical, firm, easy to operate and can exercise children’s hands-on ability to stimulate children’s interest in exploring various scientific phenomena. This toy features changeable,
